  • The “Audit Trap”: Why Misconfigured Tax Software Is Building a Silent Debt for Your Business

    By Christian Fillion E-Commerce Strategist & Founder, Marketing Media


    Growth is dangerous.

    When you started, you likely only collected sales tax in your home state. It was simple. It was manual.

    But then you grew. You started shipping to California, Texas, New York, and Florida. The orders poured in. You celebrated the revenue.

    But while you were celebrating, a silent counter was ticking in the background.

    Since the South Dakota v. Wayfair ruling, you don’t need a building in a state to owe them taxes. You just need “Economic Nexus” (usually $100k in sales or 200 transactions).

    Suddenly, you look at your Avalara or Vertex dashboard—or worse, a letter from a State Department of Revenue—and realize:

    You have been selling tax-free when you should have been collecting.

    Now, you owe that money. And since you didn’t collect it from the customer, it comes out of your profit margin. Plus interest. Plus penalties.

    You are paying an “Ignorance Tax.”

    You installed the tax software, but you didn’t configure the logic. You assumed it would “just work.”

    • You are under-collecting (creating debt).
    • You are over-collecting (inviting class-action lawsuits).
    • You are selling “General Goods” when you should be selling “Apparel.”

    You are driving 100mph with your eyes closed.

    This is why we audit the “Tax Engine” immediately. We ensure your configuration matches your actual footprint.

    1. The “Zip Code Guess” vs. The “Rooftop Precision”

    This is the most common configuration error we see.

    • The Friction: Your store calculates tax based on a 5-digit Zip Code. But in states like Colorado or Texas, a single zip code can contain three different tax districts (City, County, Special District). You charge 5% because the zip code says so, but the customer’s house is actually in a 7.5% zone.
    • The Fix: Geo-Spatial Targeting. We configure Avalara/Vertex to ignore the Zip Code and use “Rooftop” geolocation. We pinpoint the exact latitude/longitude of the delivery address to determine the precise jurisdiction.

    You pay exactly what is owed, not a penny less or more.

    The Optimization ROI: We audited a client who was under-collecting by 1.5% on every order in California due to zip-code averaging. By fixing the geolocation, we stopped them from accruing $30,000/year in back-tax liability.

    2. The “Nexus Blindspot” vs. The “Early Warning System”

    Growth creeps up on you.

    • The Friction: You think you only have nexus in 3 states. But last month, your Black Friday sale pushed you over the $100,000 threshold in Georgia and North Carolina. You didn’t flip the switch in your software. You kept selling tax-free. The liability is now building up silently.
    • The Fix: Automated Threshold Monitoring. We configure your tax engine to track sales against individual state thresholds in real-time. We set alerts: “You are at 90% of economic nexus in Illinois.”

    You turn the tax switch on before you get fined, not after.

    3. The “General Goods” Lazy Setting vs. The “Product Code Logic”

    Not all products are created equal.

    • The Friction: You mapped all your products to the default “General Tangible Goods” tax code. But you sell clothing (tax-exempt in some states), supplements (often lower tax), or digital downloads (totally different rules). You are charging tax on items that should be tax-free.
    • The Fix: UPC Mapping. We map your specific SKUs to the correct Avalara/Vertex tax codes. If you sell a t-shirt to a customer in Pennsylvania, the system automatically knows it is tax-exempt, while the mug in the same cart gets taxed.

    You stop over-charging your customers and losing sales to competitors who calculate it correctly.

    Stop The Silent Debt

    In the physical world, if you opened a new store location, you would register for taxes on Day 1. You wouldn’t just hope the government didn’t notice.

    In the digital world, hitting an “Economic Nexus” threshold is opening a new store.

    • You control the compliance.
    • You control the margins.
    • You control the risk.

    If you are selling across state lines and haven’t audited your tax settings in the last 12 months, you are likely carrying a debt you don’t know about yet.

    • Error Handling:
      • [ ] If a user makes a mistake, is the error message specific (e.g., “Invalid Zip Code”) rather than generic (e.g., “Error processing”)?
      • [ ] Does the page preserve the data already entered if the page reloads due to an error?

    IV. Marketing & Recovery (The “Safety Net”)

    Focus: Are we capturing data to save the sale?

    • Email Capture Position:
      • [ ] Is the Email Address field at the very top of the checkout process?

  • Who is Best Suited for PrestaShop?

    By Christian Fillion E-Commerce Strategist & Founder, Marketing Media


    PrestaShop is a powerful, open-source engine, but it is not a “one-size-fits-all” solution. Because it offers total architectural freedom, it is best suited for merchants who have moved past the “hobby” phase and require a platform that can be engineered to fit their specific business logic, rather than forcing their business to fit a template.

    Here is the profile of the merchant who will see the highest ROI from a PrestaShop implementation.

    1. The High-Complexity Catalog Manager

    If you sell products that aren’t just “Standard” items—meaning you have thousands of SKUs or products with hundreds of combinations (Size, Color, Material, Voltage, Fitment)—PrestaShop is built for you. Its database structure handles relational data (attributes and features) much more efficiently than SaaS platforms, which often hit “variant limits.”

    2. The International & Multi-Store Retailer

    PrestaShop is arguably the best platform for Global Commerce. It features native, robust support for:

    • Multi-Store Management: Run five different localized stores from a single back office.
    • Precise Localization: Granular control over taxes, currencies, and languages per country.
    • Geographical Compliance: Built-in tools for GDPR and European tax laws that are often an afterthought on North American platforms.

    3. The B2B & Specialized Merchant

    For businesses with “non-standard” workflows, PrestaShop’s open-source nature is a massive advantage. It is the ideal choice if you need:

    • Custom Pricing Rules: Different prices for different customer groups (Wholesale vs. Retail).
    • Quoting Engines: Systems that allow customers to request a quote rather than “Buy Now.”
    • Specific Technical Logic: Such as the Year/Make/Model fitment engine for automotive parts or restricted “Net 30” payment gates.

    4. The “Data Sovereignty” Advocate

    If you believe that you should own your data and your code, PrestaShop is your platform.

    • No Revenue Tax: You don’t pay “transaction fees” to your platform provider.
    • No Platform De-platforming: You host the site where you choose. No one can shut your store down or change the API rules overnight.
    • Full Access: You have direct access to the SQL database and the PHP source code, allowing for infinite customization.

    The Verdict: Is it for You?

    • Choose PrestaShop if: You are a growing business that needs a scalable, owned, and highly customized sales engine.
    • Avoid PrestaShop if: You are a solo-entrepreneur looking for a “zero-maintenance” drag-and-drop builder and don’t mind paying monthly app fees and transaction taxes.

    PrestaShop is for the merchant who treats their e-commerce site as a strategic asset, not just a digital brochure.

  • The Reconciliation Gap: Troubleshooting GA4 Revenue Mismatches in PrestaShop

    By Christian Fillion E-Commerce Strategist & Founder, Marketing Media


    One of the most critical technical challenges for a PrestaShop merchant is the divergence between backend database revenue and Google Analytics 4 (GA4) reporting. While a 5% margin of error is common due to ad-blockers and cookie consent, a “serious” discrepancy (15%+) usually indicates a breakdown in the data layer or the asynchronous transmission of the purchase event.

    When GA4 fails to capture the true value of your transactions, your ROAS (Return on Ad Spend) data becomes unreliable, leading to poor budget allocation and a distorted view of your store’s performance.

    The Technical Root: Event Triggers and Data Layers

    In GA4, revenue tracking relies on the purchase event, which must be populated with specific parameters (transaction_id, value, currency, items). Mismatches in PrestaShop typically stem from three failure points:

    • The “Thank You” Page Dependency: Most PrestaShop GA4 modules trigger the purchase event when the order-confirmation page loads. If a customer closes their browser after a successful payment but before the redirect to the “Thank You” page, the event never fires, and the revenue is lost to GA4.
    • Currency Conversion Loops: If your PrestaShop store operates in multiple currencies, the module must pass the currency ISO code correctly. If the backend records an order in CAD but the GA4 event defaults to USD without a conversion parameter, the totals will never align.
    • Duplicate Event Firing: If a user refreshes the order confirmation page or returns to it via their browser history, the purchase event may trigger a second time. Without a robust transaction_id deduplication check, GA4 will double-count the revenue.

    Technical Execution: Hardening the Data Stream

    To bridge the gap between your SQL database and GA4, we implement server-side verification and data layer hardening.

    1. Server-Side GTM (Google Tag Manager): Instead of relying solely on the browser (client-side), we use Server-Side GTM to intercept the order at the server level. This ensures that even if a user has an ad-blocker or closes the tab, the server sends the purchase data directly to Google’s Measurement Protocol.
    2. Hook Optimization: Ensure your GA4 module is hooked into displayOrderConfirmation for the front-end, but also consider actionValidateOrder for back-end tracking. This ensures that even “Manual” or “Bank Wire” orders are captured once validated by an admin.
    3. Strict Parameter Mapping: Verify that the value passed to GA4 excludes shipping and tax if your reporting standards require “net” revenue. In PrestaShop, this involves pulling the total_products_wt (with tax) or total_products (without tax) variables specifically.

    PrestaShop Diagnosis: Identifying the Leak

    • Real-Time Debug View: Use the GA4 DebugView while placing a test order. Check if the transaction_id in the console matches the id_order in your PrestaShop back office.
    • Database Audit: Compare the ps_orders table against your GA4 “Transactions” report for a specific 24-hour window. Identify which specific Order IDs are missing. If they are all from a specific payment method (e.g., PayPal or Stripe), the issue is likely with the redirect return-path of that specific module.

    Data accuracy is the foundation of scale. By synchronizing your backend and your analytics, you transform your data from “estimated” to “actionable.”

  • The Invisible Ceiling: Why Stale Carts are Stunting Your Average Order Value

    By Christian Fillion E-Commerce Strategist & Founder, Marketing Media


    One of the most common technical oversights in PrestaShop is treating the “Cart” page as a purely functional destination rather than a high-stakes sales environment. When a customer adds an item to their basket, they have already crossed the psychological threshold of intent. If your cart page is a “sterile” list of products with no dynamic cross-sell or upsell prompts, you are effectively hitting an invisible ceiling on your revenue.

    Low Average Order Value (AOV) is often not a product problem, but a Display Hook problem. Without automated nudges, you rely entirely on the customer to find everything they need—a strategy that leaves significant money on the table.

    The Technical Gap: Underutilized Hooks and Static Logic

    In PrestaShop, the lack of upsells usually stems from a failure to leverage the platform’s native hook system or a lack of data-driven recommendation logic.

    • Abandoned displayShoppingCartFooter: Native themes often leave this hook empty or fill it with generic “Related Products” that aren’t actually related to what is currently in the cart.
    • Lack of Dynamic Filtering: Without a specialized module, PrestaShop struggles to calculate “Frequently Bought Together” pairs in real-time. If a customer buys a camera, but your cart only suggests “New Arrivals” (like a dress), the cross-sell fails because it lacks contextual relevance.
    • The “One-Click” Barrier: Even if products are suggested, if the user has to leave the cart to view the product and then add it, the friction is too high. A technical solution must allow a “One-Click Add-to-Cart” directly within the summary view.

    Technical Execution: Activating the Revenue Engine

    To break through the AOV ceiling, we move from static pages to Intelligent Cart Logic.

    1. Contextual Cross-Selling: We implement modules like Cross Selling Pro or Automatic Related Products that analyze the id_product currently in the ps_cart table. The system then queries the ps_order_detail table to find items historically purchased with that product, presenting them as a “Complete the Set” offer.
    2. Tiered Progress Bars: One of the most effective technical “nudges” is a dynamic shipping bar. By injecting a script into cart-detailed-totals.tpl, we can show a live calculation: “Add $15 more to unlock Free Shipping!” This creates a functional reason for the customer to engage with cross-sell suggestions.
    3. Post-Purchase Upsells: The cart isn’t the only opportunity. By using the displayOrderConfirmation hook, we can offer a “one-time-only” discount on the Thank You page. This allows customers to add a complementary item to their order without re-entering payment details, leveraging the high-dopamine moment of the completed purchase.

    PrestaShop Diagnosis: Is Your Cart Leaving Money?

    • The AOV/Traffic Ratio: If your traffic is increasing but your AOV remains flat, your “in-journey” marketing is failing.
    • Hook Audit: Check your back office under Design > Positions. Look for the displayShoppingCartFooter and displayCartGridBody hooks. If no modules are attached here, your cart is functionally “silent.”
    • Mobile Friction Check: Test your cart on mobile. If cross-sell thumbnails are too large and push the “Checkout” button below the fold, they may be hurting your conversion rate more than they are helping your AOV.

    Don’t let your customers finish their journey with half-empty baskets. By implementing smart, automated prompts, you turn your PrestaShop cart into an active salesperson that never misses an opportunity.

  • The Hidden Trap of “Free”: Understanding the Total Cost of Ownership (TCO)

    By Christian Fillion E-Commerce Strategist & Founder, Marketing Media


    Choosing PrestaShop simply because it is “free” is one of the most common misconceptions in e-commerce. While the core software is open-source and has no licensing fees (unlike Shopify or BigCommerce), the Total Cost of Ownership (TCO) for a serious store is never zero.

    In the world of high-growth retail, “free” refers only to the entry point. To build a stable, high-converting asset, you must account for the specialized infrastructure and expertise required to maintain a competitive edge.

    The “Free” vs. Real Cost Breakdown

    PrestaShop is free to download, but to run a professional business, you will encounter these essential technical costs:

    • Hosting & Infrastructure: Unlike SaaS platforms, you must pay for your own servers. For a fast store, you need VPS or Dedicated hosting with optimized PHP-FPM and MariaDB settings to ensure low latency.
    • Modules & Addons: The “Free” version is a skeleton. To add basic features like advanced SEO, specialized payment gateways, or a blog, you will likely spend $50–$200 per module for professional-grade code.
    • Themes: Standard free themes are rarely optimized for high conversion. A professional, responsive theme typically costs $80–$150, and often requires custom CSS to align with your brand.
    • Maintenance & Security: You are responsible for security patches, backups, and version updates. This requires hiring an experienced developer to prevent “Development Debt” and ensure your database remains performant.

    The Strategic Advantage of Ownership

    Despite the costs, PrestaShop is often the superior choice for “serious” stores because it moves you from a rental model to an ownership model.

    1. Zero Transaction Taxes: Unlike SaaS platforms that take a percentage of your revenue, PrestaShop allows you to keep your margins. The more you grow, the more cost-effective the platform becomes.
    2. Complex Catalog Handling: PrestaShop is uniquely engineered to manage large catalogs with thousands of SKUs and unique combinations, providing a level of granular control that “simple” platforms cannot match.
    3. Bespoke API Integrations: Because the code is open, you can build deep, custom integrations with your ERP, CRM, or specialized tools like the YMM Fitment Engine.

    Strategic Diagnosis: Is PrestaShop Right for Your Budget?

    • The TCO Test: Have you calculated your hosting, module, and dev costs over a 24-month period? In many cases, PrestaShop is significantly cheaper than SaaS for stores doing over $1M/year.
    • The Customization Need: Does your business model require a “unique” checkout or product structure that standard templates can’t handle?
    • The Ownership Priority: Do you want full control over your customer data and source code without the risk of a platform-wide price hike or policy change?

    Choose PrestaShop if you want control, scalability, and ownership. Do not choose it if you are looking for a “no-cost” hobby site. A “cheap” setup often leads to broken modules and slow performance, which costs more in lost sales than a professional implementation.

  • The False Economy: Generic vs. Custom PrestaShop Themes for High-Growth Stores

    By Christian Fillion E-Commerce Strategist & Founder, Marketing Media


    For an emerging e-commerce brand, the price tag of a $90 “best-seller” theme from a marketplace is incredibly tempting. However, for a serious retailer, that $90 purchase is often the most expensive mistake they will make.

    The choice between a generic “cookie-cutter” theme and a custom-designed PrestaShop architecture isn’t just an aesthetic debate; it is a choice between a rigid, bloated framework and a high-performance sales engine. For a store doing $1M+ in annual revenue, the “cost” of a theme is measured in conversion rate drops, technical debt, and inflated ad spend.

    The Hidden Costs of Generic Themes

    Generic themes are designed to be “everything to everyone.” To appeal to the widest possible audience, developers pack them with every conceivable feature—sliders, countdown timers, mega-menus, and complex animations.

    • The Bloat Tax: Because they are “feature-rich,” generic themes load massive libraries of JavaScript and CSS, 90% of which your specific store will never use. This results in poor Core Web Vitals and high TTFB (Time to First Byte), which directly penalizes your search rankings.
    • The “Hacker” Vulnerability: Popular marketplace themes are high-value targets for exploits. Because thousands of stores use the exact same code, a single vulnerability in a theme’s built-in “Quick View” or “Newsletter” module can lead to a mass compromise of customer data.
    • Technical Rigidity: When you want to implement a specific B2B workflow—like a “Net 30” gate or a custom Sales Rep attribution field—generic themes often “break.” Their code is so tightly coupled with their own styling that custom development becomes a nightmare of “patching” rather than “building.”

    The Investment Value of Custom Design

    A custom PrestaShop theme is built from the ground up (often using a lean framework like the PrestaShop “Classic” starter or a clean Tailwind-based engine) to serve your specific customer journey.

    • Architectural Speed: Custom themes only load the scripts necessary for your specific functionality. By optimizing the Largest Contentful Paint (LCP), you provide the “instant” feel that high-end shoppers expect, leading to higher conversion rates and lower bounce rates.
    • Quality Score Optimization: For stores running aggressive Google Ads, a custom theme allows for the creation of “Tunnel” landing pages. These pages strip away distractions and align perfectly with ad intent, boosting your Quality Score and lowering your Cost-Per-Click (CPC).
    • Scalability and Maintenance: Custom themes follow PrestaShop’s “Override” standards. This means when you update PrestaShop core or add a new payment module, your theme remains stable. You aren’t constantly fixing CSS conflicts created by a third-party developer’s “creative” coding.

    The Bottom Line: ROI Over Initial Price

    If a generic theme results in a 1% lower conversion rate than a custom-optimized site, and your store generates $100,000 in monthly traffic, you are losing $1,000 in revenue every single month. Within a year, the “cheap” theme has cost you more than the investment in a professional custom design.

    • Generic Themes are for testing a concept or launching a hobby.
    • Custom Themes are for scaling a business and protecting your margins.

    Serious retailers don’t look for the lowest entry price; they look for the highest technical ceiling.

  • The Cost of “Cheap”: Why the Least Expensive Developer is Often the Costliest

    By Christian Fillion E-Commerce Strategist & Founder, Marketing Media


    In e-commerce, the “Lowest Hourly Rate” is a siren song that leads many PrestaShop merchants toward technical bankruptcy. Hiring an inexperienced or “budget” developer might seem like a way to save on initial overhead, but in a complex ecosystem like PrestaShop, you aren’t paying for their time—you are paying for their education.

    The “least expensive” developer is almost always the costliest because they lack the architectural foresight to build for scale. They provide temporary patches that eventually fail, leading to lost sales, security vulnerabilities, and “Development Debt” that costs five times more to fix than it would have cost to build correctly the first time.

    The Hidden Expenses of Low-Cost Development

    When you hire based on price rather than expertise, your “savings” are quickly eroded by three specific technical failures:

    • The “Re-Fix” Cycle: Budget developers often treat symptoms rather than root causes. You might pay $20 to fix a checkout bug today, but because they didn’t resolve the underlying hook conflict, the bug returns next week—along with a new invoice.
    • Core File Contamination: Inexperienced developers often modify PrestaShop core files directly instead of using the Override system. This makes your store impossible to update. When a critical security patch is released, your “customized” core will break, requiring a total (and expensive) rebuild.
    • Performance Degradation: A cheap fix often involves “heavy” code—unoptimized SQL queries or redundant JavaScript libraries. This bloats your Time to Interactive (TTI), hurting your SEO rankings and driving away mobile shoppers who won’t wait more than three seconds for a page to load.

    The Marketing Media Advantage: Architectural Stability

    At Marketing Media, we believe that true economy is found in doing it right once. We focus on architectural integrity, ensuring that every line of code adds value rather than debt.

    1. Clean, Standardized Code: We follow the official PrestaShop Coding Standards. This ensures your store remains “upgrade-ready” and that any future developer can easily understand the work, reducing long-term maintenance costs.
    2. Strategic Problem Solving: We perform Root Cause Analysis on every bug. We don’t just hide an error message; we fix the structural conflict that caused it, ensuring the “zombie bug” never returns to haunt your bottom line.
    3. Scalable Infrastructure: We build for where your business is going, not just where it is today. Our solutions are designed to handle high SKU volumes, complex B2B pricing, and heavy traffic surges without requiring constant “emergency” repairs.

    [Image: The “Vicious Cycle” of Cheap Development vs. The “Growth Cycle” of Professional Engineering]

    Strategic Diagnosis: Are You Paying the “Cheap Tax”?

    • The Recurring Invoice: Are you paying for the same technical issues month after month?
    • The “Fragile” Site: Are you afraid to install a new module or update your theme because you know the whole site might “break”?
    • The Invisible Leaks: Is your conversion rate lower than the industry average despite having high-quality traffic? Your “budget” code might be creating friction you can’t see.

    Investment in a highly experienced partner like Marketing Media is an investment in certainty. Stop paying for “patches” and start investing in a platform that actually supports your growth.

  • The Conversion Blind Spot: Why Your PrestaShop Sales Aren’t Reaching Your Ads

    By Christian Fillion E-Commerce Strategist & Founder, Marketing Media


    The most dangerous scenario for a digital retailer is “blind spending”—a state where your PrestaShop store is actively generating revenue, but your advertising platforms (Google Ads, Meta, LinkedIn) report zero conversions. This disconnection creates a catastrophic feedback loop: because the ad algorithm “thinks” it is failing, it stops optimizing for buyers and begins wasting your budget on low-intent traffic, or worse, shuts down your best-performing campaigns entirely.

    When your tracking is broken, you aren’t just missing data; you are losing the ability to calculate Return on Ad Spend (ROAS), effectively flying your business into a storm without instruments.

    The Technical Breakdown: The Silent Failure of Signals

    In a PrestaShop environment, conversion tracking failure is rarely a total blackout; it is usually a breakdown in the “handshake” between the server and the browser.

    • The Redirect Trap: Most tracking pixels trigger on the order-confirmation page. If a payment gateway (like a third-party hosted checkout) fails to redirect the user back to your store, or if the user closes the window during the processing delay, the “Purchase” signal is never sent.
    • JavaScript Execution Blocks: Modern browsers and privacy-focused extensions (Ad-Blockers) frequently target the specific scripts used by conversion pixels. If your tracking relies solely on client-side JavaScript without a server-side backup, a significant percentage of your “real” sales will remain invisible to your ads manager.
    • The ID Mismatch: Advertising platforms require a unique transaction_id to deduplicate and verify sales. If your PrestaShop module generates IDs that don’t match the format expected by the ad platform—or if it sends a generic “checkout” event instead of a specific “purchase” event—the platform will reject the data as invalid.

    The Data Layer Disconnect

    The “Data Layer” is the invisible bridge that carries order details (Value, Currency, Items) from your SQL database to the tracking pixel.

    • Variable Corruption: If a theme update or a new module modifies the order-confirmation.tpl file, it can break the variables that populate the Data Layer. When the ad platform receives an event with a “Null” value for price or currency, it treats the conversion as a non-event.
    • Consent Mode Interference: With the rise of GDPR and CCPA, “Consent Mode” acts as a gatekeeper. If your consent banner is improperly integrated with your PrestaShop hooks, it may block the conversion signal even for users who have opted in, leading to massive under-reporting of successful sales.

    Operating an e-commerce store with broken tracking is like running a marathon with your eyes closed. You might be moving forward, but you have no idea if you’re still on the path to the finish line.

    • JavaScript Execution Blocks: Modern browsers and privacy-focused extensions (Ad-Blockers) frequently target the specific scripts used by conversion pixels. If your tracking relies solely on client-side JavaScript without a server-side backup, a significant percentage of your “real” sales will remain invisible to your ads manager.
    • The ID Mismatch: Advertising platforms require a unique transaction_id to deduplicate and verify sales. If your PrestaShop module generates IDs that don’t match the format expected by the ad platform—or if it sends a generic “checkout” event instead of a specific “purchase” event—the platform will reject the data as invalid.

    The Data Layer Disconnect

    The “Data Layer” is the invisible bridge that carries order details (Value, Currency, Items) from your SQL database to the tracking pixel.

    • Variable Corruption: If a theme update or a new module modifies the order-confirmation.tpl file, it can break the variables that populate the Data Layer. When the ad platform receives an event with a “Null” value for price or currency, it treats the conversion as a non-event.
    • Consent Mode Interference: With the rise of GDPR and CCPA, “Consent Mode” acts as a gatekeeper. If your consent banner is improperly integrated with your PrestaShop hooks, it may block the conversion signal even for users who have opted in, leading to massive under-reporting of successful sales.

    Operating an e-commerce store with broken tracking is like running a marathon with your eyes closed. You might be moving forward, but you have no idea if you’re still on the path to the finish line.
