We customize your online store to fit the way you work: we add what CS-Cart lacks out of the box, fix what was broken before us and connect the services you need. We look for a ready-made solution first and write our own code as a separate add-on, with no core changes.

Tasks

What stores come to us with

New feature

Bug fixes

We fix what previous developers or updates broke: emails, the cart, shipping calculation, imports, the customer account.

Integrations

Connecting your store to ERP and accounting systems, CRM, warehouse, payment and shipping services and partner APIs. More on the integrations page.

Checkout

We simplify the cart and checkout and add payment and shipping methods, guest checkout and SMS login.

Invoices and other documents, print forms, receipts, exports for accounting and reports for managers.

Marketplace

Vendor panel, commissions and payouts, vendor storefronts and product moderation on Multi-Vendor.

Interface and mobile version

Product page, filters, menus and the mobile version: we fix what keeps customers from placing an order.

How we work

How we customize without breaking your store

Four rules that save money now and at the next upgrade.

Ready-made first

If a CS-Cart setting or a ready-made add-on from our store solves the task, we will tell you: it is cheaper and more reliable than development.

As a separate add-on

We write our own code as an add-on built to CS-Cart standards: you can enable, configure and disable it in the admin panel without touching the rest of the store.

No core changes

We do not modify the CS-Cart core, so a platform upgrade will not overwrite your customizations.

Full 100-day warranty

If after delivery the feature does not work as agreed, we fix it free of charge.

From our projects

What we have already built

Tasks from projects of the last two years. We do not disclose store names.

Four-tier wholesale pricing

A mobile accessories store with 15,000 products: wholesale prices per customer, cart recalculation by order total, invoices sent by email and QR-code payment.

Intermediary marketplace

A fasteners marketplace: anonymous vendors, hidden buyer data, sales by the pack, SMS sign-up and a new supplier panel built as a separate add-on.

Cross-border shipping

A marketplace in Canada and the US: live UPS, FedEx and USPS rates, batch label printing, customs documents and a switch of shipping aggregator without closing the storefront.

Calculator and partial prepayment

A marketplace for septic tanks and fences with installation: price calculation for common products, three payment schemes, bundles of products and services from different vendors.

Stock at partner warehouses

A B2B spare parts store serving two countries: partner stock arrives via API and is shown on the product page.

PC configurator

An electronics store with 35,000 products: a step-by-step PC builder where each next step shows only compatible components.

From the task description to the warranty after delivery.

01
Task analysis

We clarify what the business needs and review the store, add-ons and data. We look for a ready-made solution.

02

We describe how we will do it, how many hours it takes and what it costs. Work starts only after you approve.

03

We build and test on a copy of the store while the live site keeps working.

04
Delivery and warranty

We move the work to the live store and show you the result. Full 100-day warranty.

Pricing

How much store customization costs

We work by the hour and estimate every task before starting. If a ready-made add-on covers the task, you pay only for its license and setup.

Before you order

Questions about online store customization

Answers to what clients ask before ordering.

The price depends on the hours of work, from $30 per hour, and we estimate the task before starting. A small fix takes from one hour; a typical customization takes from one to several business days. The estimate is free.

Usually within 1–2 business days after we understand the task and get access to the store.

Yes. First we review the code, add-ons and core modifications to find the risks before work starts. If the store has a lot of third-party code, we recommend starting with a technical audit.

No, if it is built as an add-on without core changes, which is how we work. During an upgrade such an add-on is adapted along with the others.

We fix it free of charge: the Full 100-day warranty applies after delivery.

Not for one-off tasks: we take them one at a time. If there are many tasks and they keep coming, technical support or a dedicated team is more convenient, since the developer already knows your code.

Yes: the vendor panel, commissions and payouts, vendor storefronts, moderation and common products.

Yes. It is the easiest way to see how we work before taking on a big project.
