How Vervali Load Tests Shopify Stores Before Black Friday
How Vervali load tests Shopify and Shopify Plus stores before Black Friday: the Shopify rules, what gets tested, when to start and what it costs.
Magento and Adobe Commerce stores, Magento 2 migration and checkout, tested before go-live. We build the catalogue, wire the payments and multi-store rules, and prove the store takes money on the devices your customers use before launch day.

Catalogue, multi-store rules and checkout on Magento, tested before the first paid order.
Theme, catalogue, cart and checkout on Magento or Adobe Commerce. Multi-store views and catalog indexing are named in the quote, because that is where a large Magento catalogue shows its load.
Magento 1 to Magento 2, or another platform onto Magento. Products, customers and order history move with the redirect map agreed before cutover.
ERP, CRM, tax, shipping and marketing tools on the order path, named in the quote. A custom module when a marketplace extension cannot carry the rule.
Stripe, PayPal and Adyen wired for authorise, capture, decline, refund and timeout. PCI DSS controls on the store are tested before go-live.
Shared catalogues, store views, contract pricing and customer groups. The quote names which views and price lists are in the first release.
Catalog index, cache and the queries a large catalogue puts on category pages and checkout, tuned before the store takes live traffic.
A Magento theme that cannot take payment is not a store.
Free Store ReviewThe Magento issues that show up once the catalogue and the checkout are both live.
Heavy themes and a stuck index that make category pages stall. Cache, index and the queries behind them are tuned.
Declines, timeouts and refunds the theme never handled. Each payment path is proved before a live customer hits it.
A store that cannot take the next platform release. The move to Magento 2 is scoped with the catalogue and the checkout.
Marketplace modules that override the same checkout step. We keep the ones the order needs and replace the ones that fight.
The same team that writes the store proves checkout, price lists and devices before launch.
Authorise, capture, decline, refund and timeout, on the gateways the quote names, before a real customer pays.
Store views, customer groups and contract prices checked so the shopper sees the price that applies to them.
Phones, tablets and browsers taken from your analytics. Checkout gets the deepest pass, including mobile web.
Traffic modelled on your own peaks through cart and payment. Deeper sale-day work runs through ecommerce testing.
Stores built and tested by the same team, measured in sales, abandonment and checkout speed.

Critical bugs and a slow checkout were capping conversion. After six months, conversion was higher, critical bugs were fewer, and checkout was faster.

A free look at the catalogue, the store views, the extensions and where orders already leak.
Migration, modules and checkout named up front, then a fixed price for that release.
Sprints with a working store to review, and the money path tested as it is built, including price lists and payments.
Go-live checks, then a named support line for patches and small catalogue changes. Longer version work is its own engagement.
One accountable team for the Magento build and the test pass behind it.
Developers backed by an ISO/IEC 17025 accredited lab and CMMI Level 3 process, so the store that launches is the store that was tested.
Multi-store, contract pricing and a large catalogue are the reason to be here. A smaller package store is scoped on ecommerce solutions.
Working hours overlap 9am to 1pm Eastern, with delivery from India and one point of contact through launch.
