Custom add-ons · API integrations · Maintenance
Your store should support your business processes. Custom development helps make that happen.
I’m Jeff at Door27. I build custom CS-Cart features and integrations, from payment and shipping connections to inventory tools and reporting portals.
01 / Custom CS-Cart development
A ready-made add-on may cover part of a requirement. Custom development can address the details that are particular to your business.
Add functionality to the storefront or admin area, introduce custom fields, and adapt the steps your team follows when managing orders and information.
Build stock-management features around how products are stored, tracked, and handled, including workflows that go beyond the standard product quantity.
Make the information in your store more useful through tailored reports, reporting portals, and tools for moving data into or out of CS-Cart.
Adapt the customer-facing parts of your store with template changes, responsive layouts, and features that support the way your customers buy.
Client work is private. These descriptions explain the types of functionality I develop without identifying clients or exposing their systems.
02 / API integrations
An integration needs to fit both systems and the work happening between them. We’ll look at what data needs to move, when it should move, and what happens if something fails.
Connect payment services and adapt the handling of payment events, statuses, and related workflows.
Experience includes Stripe and PayPal integrations.
Connect carrier services and support shipping-related data, label, and tracking workflows.
Experience includes UPS, FedEx, USPS, and Canada Post integrations.
Exchange information with inventory systems, reporting tools, and other services your business uses.
API connections, webhooks, and structured data feeds.
Send its name, the connection you need, and any API documentation you have. Availability depends on the service’s API, account access, and your store’s setup.
Tell me what needs connecting03 / Ongoing maintenance
Your website keeps changing as your business, integrations, and customer needs evolve. Ongoing work can help you maintain existing functionality and plan the next improvement.
Discuss ongoing supportReview the work needed when your CS-Cart version, add-ons, theme, or connected services change.
Refine existing tools, extend features, and address the small changes that accumulate as your team uses the store.
Investigate errors, integration failures, and unexpected behavior in your existing setup.
More about troubleshooting04 / How I work
You work directly with me, from the first conversation through development and review.
I aim to keep custom functionality separate from CS-Cart’s core files, using add-ons and hooks where appropriate. This makes the changes easier to identify and maintain; compatibility still needs reviewing when the store is upgraded.
Understand the desired result, store version, existing customizations, and connected systems.
Discuss scope, dependencies, pricing, and how the work will be tested before proceeding.
Build and check the changes, using a development copy where appropriate, before planning the live update.
Before we talk
Yes. We’ll first review the existing store and the changes you need. Information about previous customizations and any available documentation helps establish the scope.
I work with CS-Cart and Multi-Vendor, including older installations. Feasibility depends on your version, hosting environment, and existing add-ons. Send the version number with your inquiry if you know it.
Often, yes. I’ll need to understand the add-on, the change you want, and whether its source code and license permit the work. Compatibility with the rest of your store also needs reviewing.
Yes. A project can begin with one integration, custom feature, or improvement. We can discuss additional development or ongoing maintenance separately.
Access may be needed to investigate or implement the work. Start by sharing your website address and a description of the requirements. We can then discuss the access needed and how to provide it securely. Please don’t include passwords in your initial inquiry.
Send your store address, what you want to achieve, any relevant add-ons or services, and your timing requirements. I’ll review the information and ask for any details needed to discuss scope and pricing.
Let’s work through the details.
A custom feature, a new integration, or ongoing maintenance starts with a conversation about your store.
