What We Build on Shopify
Theme, apps and checkout around the hosted core, tested before the first paid order.
Store Build
Theme, catalogue, cart and the order path on Shopify or Shopify Plus. Markets and the theme sections in the first release are named in the quote.
Shopify Plus
Checkout extensibility and B2B, when those are named in the quote. The hosted checkout core stays with Shopify. Theme, apps and Plus scripts are the build around it.
Apps and Integrations
Custom apps plus payment, shipping, tax and the back office, named in the quote. A custom app when a public app cannot carry the rule.
Checkout and Payments
Stripe, PayPal and Adyen wired for authorise, capture, decline, refund and timeout, on the steps Shopify allows. PCI DSS controls on the store are tested before go-live.
Migration to Shopify
Products, customers and order history moved from Magento, WooCommerce or a custom store, with the redirect map agreed before cutover.
Theme and Speed
Sections, images and the scripts a theme loads, tuned so category and product pages stay usable on the phones that already buy.
A Shopify theme that cannot take payment is not a store.
Free Store ReviewStore Problems We Fix
The Shopify issues that show up once the catalogue and the checkout are both live.
Apps Fighting Checkout
Public apps that override the same cart or checkout step. We keep the ones the order needs and replace the ones that fight.
Checkout Failures
Declines, timeouts and refunds the theme never handled. Each payment path is proved before a live customer hits it.
Unfinished Theme
Sections and a logo on a demo theme, with no apps on the money path. The quote names the apps and the checkout the customer uses to pay.
Locked Checkout Steps
A step Shopify will not open. That limit is in the design, and the quote covers the theme, apps and Plus scripts around it.
Tested Before It Takes Money
The same team that writes the store proves checkout, apps and devices before launch.
Checkout and Payments
Authorise, capture, decline, refund and timeout, on the gateways the quote names, before a real customer pays.
Apps on the Order Path
The apps and Plus scripts that change price, shipping or the cart, checked together so they do not cancel each other.
Devices From Your Data
Phones, tablets and browsers taken from your analytics. Checkout gets the deepest pass, including mobile web.
Sale-Day Load
Traffic modelled on your own peaks through cart and payment. Deeper sale-day work runs through ecommerce testing.
Results From Ecommerce Engagements
Stores built and tested by the same team, measured in sales, abandonment and checkout speed.

Frequently Asked Questions
Shopify development is the build, change and migration of a store on Shopify or Shopify Plus: theme, apps and the checkout steps Shopify lets you change. The hosted checkout core stays with Shopify. The work covers a new store, a move onto Shopify, and the apps the order path actually uses. Every store is tested on the money path before it takes a live order. Coverage is 9am to 1pm Eastern, with delivery from India.
The weeks follow the catalogue, the apps and how much of checkout Shopify Plus actually opens up. A theme with a short app list is the shorter engagement. Plus with B2B, markets and a custom app on the order path takes longer. We name the weeks in the written quote after a free store review, once the first release is written down. Delivery is from India, with overlap 9am to 1pm Eastern.
Yes. We move products, variants, customers and order history from Magento, WooCommerce, BigCommerce or a custom store, then rebuild the theme on Shopify. Redirects are mapped so the pages search already sends keep their place. Hosted checkout on Shopify works differently from the checkout you leave, so the quote lists what will change before any catalogue moves. The new checkout is tested before the store takes a live order.
Yes, when a public app cannot carry a rule on the order path. Payment, CRM, loyalty and the other apps named in the quote are in that work. A custom app is the path when the Shopify surface will not hold the rule. If Shopify locks a step, that limit is written into the design before the build starts. The quote names each app before anyone writes code.
The money path is checked on the phones, tablets and browsers that already generate orders, including mobile web, before go-live. The device list comes from your analytics. Checkout gets the deepest pass, because that is where most stores lose the sale. Theme sections are built so those devices can finish an order, inside the layout Shopify allows. Those devices are named before the build starts.
Yes, when ERP, CRM, tax, shipping or marketing tools sit on the order path and are named in the quote. Stripe, PayPal and Adyen are wired when they are the gateways the store already uses. A custom app is the path when a public app cannot carry the rule. PCI DSS controls on the store are tested before go-live. We do not certify the store. The quote lists each system before the build starts.
Yes. Support is a named line in the quote: fixes, app updates, small catalogue changes and the operating work the store still needs after the first paid order. Theme and app updates can run on a monthly retainer. Longer version work is scoped as its own engagement. Coverage is 9am to 1pm Eastern, with delivery from India. A free store review shows what already has to stay live, so support is priced before launch.
Clutch lists Vervali at $25 to $49 per hour. A Shopify build is quoted as a fixed price once the catalogue, apps, Plus checkout and integrations are scoped. A theme with few apps and a Plus store with B2B are different quotes. Ongoing app and catalogue work can run on a monthly retainer. Tool licences and extra device coverage are named in the estimate. The written price follows a free store review.
