What We Test on an Ecommerce Platform
A checkout that takes the money, keeps stock right, and works on the phones that already buy.
Checkout and Payment Gateway
Does the customer pay, and does the store capture that payment when Stripe, PayPal or Adyen is slow, fails or returns a partial response. A broken checkout is abandoned revenue sitting in the cart.
Cart, Promotions and Discounts
This is where most silent revenue loss lives: stacking rules, gift cards, BOGO, threshold discounts and coupons that apply twice or not at all. The store looks fine. Margin and conversion are not.
Catalogue and Search
Wrong price, missing variant, search that cannot find the SKU the ads promised. The customer leaves before a cart exists. Relevance is a sales problem, not a nice-to-have.
Order, Inventory and Fulfilment
Including the failure cases when stock runs out mid-order, a warehouse is late, or the OMS and the storefront disagree. Oversell and ghost stock become chargebacks and support load.
Account, Returns and Refunds
Login, address books, wishlists, RMA and refunds that never hit the gateway. A return path that fails is a repeat customer you will not get back, and a finance reconciling problem.
Cross-Device and Browser
The matrix comes from your analytics: the phones and browsers that actually buy. A checkout that works on desktop Chrome and dies on iOS Safari is a peak-season surprise you can find in week one.

Book a CallPlatform Coverage
The defects that only show up on Shopify Plus, Magento, WooCommerce or a headless stack. Not a generic store test.
Shopify and Shopify Plus
You do not control the hosted checkout core. We test what your theme, apps, checkout extensibility and Plus scripts actually do around it: payments, shipping, discounts, validation and the thank you path. Plus changes the surface: checkout customisation, Launch, and B2B. If a flow is locked by Shopify, that is in the design before the quote, not a surprise in week two.
Magento
Multi-store views, catalog indexing and cache behaviour are where Magento breaks under load. A store that is fine at 50 concurrent sessions can stall when indexers lag or a second storefront shares the same catalog. We test those joins, not only the Luma or Hyva theme.
WooCommerce
Plugin conflicts are the dominant defect class: payment, shipping, membership and page-builder plugins that pass on their own and fail together at checkout. We treat the plugin set as the product, because that is what your customer actually runs.
Headless and Custom
The front end and the commerce API fail independently. We test both: the storefront the shopper sees, and the cart, checkout and inventory APIs it calls. A green UI on a stale API is how custom stacks lose orders without an error on screen. Build work, when you need it, sits on ecommerce solutions.
Peak-Season Readiness: Load Testing Before Black Friday
Checkout under last year's peak, six to eight weeks before the sale, so there is time to fix what fails.
What We Load
Traffic is modelled from last year's own analytics, not a flat script. The checkout and payment path runs under peak concurrency, not the home page. The promotion that will actually run is in the test. We also test the failure mode: what the site does when the payment provider slows down, rather than when it fails cleanly.
When It Has to Start
Six to eight weeks before Black Friday, Cyber Monday or your own sale. The test is the short part. The fixes, the retest and the payment-provider conversation take the rest. Starting in November for a late-November peak is how stores find the bottleneck on the day.
A Real Peak-Load Result
A Mumbai supplements retailer: 40% faster pages and 50% more mobile conversions after performance work ahead of peak traffic. The same discipline applies to a US sale day: checkout first, then the rest of the site.
Payments, PCI DSS and Security Testing
The gateway you run, the scripts on the payment page, and evidence that would stand a PCI DSS conversation. We do not certify anyone.
Payment Integration
Authorise, capture, fail, refund and timeout on the gateway you run. Tokenisation and what is stored on your side versus the provider. A stored PAN you did not mean to keep is the finding that matters.
Checkout Under Attack
Injection and session attacks on the checkout, plus the third-party scripts on the payment page. Those scripts are the most common route to a card-skimming incident. Agreed in-scope assets only.
PCI DSS Evidence
We test whether your controls and evidence would stand up to a PCI DSS conversation. That is not a certificate. If you need a QSA, that is a different vendor. Compliance testing is the sibling page for the wider control set.
Accessibility for Retail (ADA)
A checkout a screen-reader user cannot finish is a lost sale. That is the retail case for ADA, not a legal memo.
What We Test on the Money Path
Keyboard and screen-reader completion of search, product, cart, checkout and payment. Labels, errors and focus that a shopper can actually use. If the path fails, the sale fails, and in US retail that is also where claims concentrate.

A dated pre-peak pack, a retainer on every release, or a named tester. Typical work starts at $25 to $49 per hour.
One-Off Pre-Peak
A dated load and checkout programme before Black Friday or your own sale. Suits a store that is quiet most of the year and must not fail on the days that pay for the rest. Fixed scope, six to eight weeks out.
Release-By-Release Retainer
Regression on every merchandising and platform release. Suits a store that ships weekly campaigns, new SKUs and promo rules, and cannot wait for a project kickoff each time.
Dedicated Tester
A named tester inside your retail team, billed monthly. Suits a high-volume store or marketplace where order flow is always on and you want the same person in stand-up, in US hours, without a US payroll.
What Ecommerce Testing Costs
$25 to $49 per hour. A one-off pre-peak engagement is quoted as a fixed price. Retainers and dedicated testers are billed monthly. Tool licences, extra devices and peak-load environments are named in the estimate.

Frequently Asked Questions
Ecommerce testing is the work of proving the store will take money, keep stock right and not fail a customer on the path from search to paid order. It covers checkout and payment gateways, cart and promotions, catalogue and search, order and inventory, returns, cross-device behaviour, accessibility and peak-season load. Defects in those paths cost abandoned carts and lost sales, not just tickets.
Yes. We test the payment integration you actually run: authorise, capture, fail, refund and timeout. Stripe, PayPal and Adyen are in that work when they are on the checkout. We also look at tokenisation, what is stored, and the third-party scripts on the payment page. We test your controls for PCI DSS. We do not certify anyone.
Yes, within what Shopify lets a merchant control. Theme, checkout extensibility, Plus scripts and custom apps are in scope. The hosted checkout core is not something we rewrite. We test what your Plus setup does around it: payment apps, validation, shipping, discounts and the thank you path. If a flow is locked by Shopify, we say so in the design before we quote.
We model traffic from last year's own analytics, not a flat script. The checkout and payment path is loaded, not only the home page. The promotion that will actually run is in the test. We also test what the site does when the payment provider slows down. This work needs six to eight weeks before peak, because the fixes take longer than the test. Method detail is on the performance testing page.
Yes. The matrix comes from your analytics: the browsers, OS versions and devices that generate sessions and orders. We test the money path on those, including mobile web. You are not paying to certify browsers your customers do not use.
A named team is usually assigned within a week of NDA and access. A free checkout-flow test on five devices is the fastest first look. A full peak-season load programme should start six to eight weeks before Black Friday or your sale, so there is time to fix what the test finds.
Work is scoped to the store, the platforms and the depth you need, then quoted before we start. Clutch lists Vervali at $25 to $49 per hour. A one-off pre-peak engagement is a fixed price. A release-by-release retainer and a dedicated tester are billed monthly. Tool licences and extra device coverage are named in the estimate.
Yes. Vervali does ecommerce development and QA together. Storefront work lives on our ecommerce solutions page. Two of the cases on this page are stores we built and tested. You can hire testing alone, or one team for build and test.
