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.
Fintech and Banking Software,
Built and Tested
Vervali builds payment, lending, KYC and digital banking platforms, then tests them. PCI DSS controls are designed into the build, the same team tests it, and we do not issue a PCI, FDIC or SEC certificate. Delivery is from India with a 9am to 1pm Eastern overlap.

Payments, Lending, KYC and Digital Banking, Built and Tested
Banking software where the controls are designed in, then tested by the same team.
Payments and Settlement
Capture, retry, reverse and the ledger that has to agree. A payment that looks captured while settlement never posted is not a Jira ticket.
Lending and Origination
Application to disbursal, document generation and the rule a borrower actually accepted. A rate that moved overnight without a spec is an audit miss.
KYC and Onboarding
Identity vendors, the slow timeout and the applicant who already started on a phone. A timeout that looks like a pass is the usual miss.
Mobile Banking
Session handling, the offline case, push tied to a payment and deep links from email. Device coverage is on mobile application testing.
PCI DSS in the Build
Card data handling, access control, audit logs and encryption designed in rather than bolted on. Method is on fintech compliance.
Cores and Processors
Core systems and payment processors are in scope when they are the path money already uses. A takeover of a prior vendor is named up front.

The product build sits here. These are the neighbouring pages.
The Sector Testing Pack
Banking journeys, PCI DSS controls and load that matches salary day or month end, tested by a separate pack. See fintech and banking.
Control-by-Control Method
Testing against the controls a bank risk team will ask for, with a dated evidence pack a reviewer can read. See fintech compliance.
Wider Product Work
Custom software beyond banking, built to the same standard by the same engineering team. See custom software development.
The APIs Behind It
The APIs payments and onboarding depend on, built with contract and security tests that ship with them. See API development.
PCI DSS, SOC 2 Readiness and Evidence
What is built and tested, and what a bank risk team will ask to see.
PCI DSS Where Card Data Moves
The card data you touch and what is tokenised, built in and tested, with access control and audit logging in place.
Data Protection and Evidence
Data protection and the controls evidence a bank risk team will ask for, produced as the build runs.
Attack Work, Scoped Separately
Application and API attack testing runs on agreed in-scope assets. See security testing and penetration testing.
Controls Tested, Evidence You Can Use
We test your PCI DSS controls and the FDIC or SEC rules named in your quote, and hand you evidence your risk team can read. The same testing supports your SOC 2 readiness. Vervali holds ISO/IEC 27001 and builds and operates on AWS and Azure.

Book a CallProof From Delivery, Banking Software That Had to Work
Three engagements, sector and country only. They show Vervali has built and tested financial systems at that scale.
India · two leading private-sector banks
Loan processing and agent onboarding were too slow for the compliance required. Vervali built and tested the paths from application to disbursal and the onboarding that puts an agent on the floor. After: 60% faster loan processing, 50% less agent onboarding time and 100% compliance on the controls named.

A first assessment is quoted after that look: the build, the controls in scope and the load shapes that apply.

Start With One Flow
A free gap check on one flow is the first look. We do not copy production customer records into a test environment.

Build, Test and Keep It Current
The same team builds and tests, and the pack stays current as rules, vendors and releases change.
Frequently Asked Questions
Yes. Cores, payment processors and identity vendors are in the quote when they are the path money already uses. A takeover of a prior vendor is named up front. Testing of those integrations is on API testing services, and a free gap check shows where to start.
We do not sell a named gateway as the default. Processor integrations are in scope when they are on the path, and we test PCI DSS controls where card data moves without issuing a PCI certificate. Attack work is scoped separately on security testing.
Yes, when those currencies and countries are in the quote. Settlement windows, FX rounding and a statement that no longer matches the screen are where this fails. We have delivered banking work in India, the UAE and New Zealand. Named countries and rules are agreed in the quote.
It follows products, cores, whether KYC is in scope and how much already exists, so we do not publish a fixed band. The quote names the timeline after a free gap check on one flow. Testing sits in the same team, which shortens the loop between a fail and a fix.
Yes, when the load shape is modelled from your own volumes, not a round number of virtual users. Salary day, month end and a campaign are different shapes, and each is tested on its own. We do not quote a concurrent-user figure we cannot evidence. See performance testing.
Yes, when a retainer is in the quote. Ongoing releases are on software maintenance and support. Coverage is 9am to 1pm Eastern with delivery from India. A one-off build with no retainer is named that way, and a free gap check shows what ongoing support would involve.
We test PCI DSS where card data moves, access control, audit logging and the controls a bank risk team will ask for. FDIC, SEC and similar rules are named in the quote as tests, and we do not issue a certificate. See fintech compliance.
Most engagements land at $25 to $49 an hour blended. Price follows products, cores, KYC, load and whether PCI DSS testing sits in the same week. A free gap check on one flow shows the surface before anyone writes a quote.
