B2B and wholesale pricing
Company accounts, buyer roles, negotiated price books, minimum order quantities, payment terms and approval steps. Each customer sees the prices and terms agreed with them.
B2B portal development →Custom ecommerce development services for retailers who outgrew their platform
Shopify or BigCommerce got your store this far. Now each new price rule needs another app, and each theme update breaks something. Our custom ecommerce development services help retailers connect sales, stock and fulfilment. We develop the parts your platform can't handle and keep the parts that work.
We're a development team, not a platform vendor. We advise, build and support the software, and you own the code.

Signs your store has outgrown its platform
Revenue alone rarely pushes a store off its platform. Business rules do. These are the signs we hear most from B2C and B2B retailers:
Two or three of these usually mean it's time for custom work. That doesn't always mean leaving your platform.
- 01A basic feature needs a paid app, and the apps now cost more than the plan.
- 02Two apps change the shopping cart in different ways, and nobody knows which one broke checkout.
- 03Wholesale customers need their own price lists, minimums and terms, and native B2B tools don't stretch that far.
- 04Products have more variants or options than the product catalog allows.
- 05Checkout can't follow your rules for payment, shipping or approval.
- 06Custom code means you skip theme updates, because the last one took a week to fix.
- 07A small change on the site needs a developer and a two-week wait.
Choose the lightest path
Custom ecommerce development: three ways we can build it
We start from the left column and move right only when the left side can't do the job. For many retailers, a custom app and a cleaner store cost far less than a rebuild.
| Criteria | We extend your platform | We develop a headless storefront | We build fully custom commerce |
|---|---|---|---|
| What we develop | One custom app or service that replaces a chain of plugins | A custom front end, while checkout, catalog and orders stay on Shopify or BigCommerce | Storefront, cart, checkout and order logic, built around your business |
| Good fit when | The platform is fine, but a few rules don't fit | You need a different shopping experience or faster pages | Your pricing, catalog or order flow can't live inside any platform |
| Effort and risk | Lowest | Medium: you also run a front end | Highest, so we deliver it in stages |
| What you own | The custom app and its code | The storefront code | All of it |
Modules
What we develop in custom ecommerce website development
We develop around business rules — pricing, checkout, catalogs and admin tools — not around a tech stack for its own sake.
Checkout rules your platform won't allow
Custom payment options, shipping logic by product or region, purchase order fields, split shipments and approval before payment. Payment gateways and fraud checks stay in place.
Product configurators and complex catalogs
Configurators for products with many options, bundles and made-to-order items. Prices and rules update as the customer makes choices.
Subscriptions, autoship and referral programs
Recurring orders with your own rules for skipping, swapping and pricing, plus referral or partner shops.
Personalization and search
Product recommendations, saved lists and search that understands your catalog, built on your own customer and order data.
Admin tools for your team
Screens your staff use every day: order edits, bulk price updates, approval queues and reports. Built for the way your team works, so fewer tasks need a developer.
Headless, only where it pays
Headless commerce development services, only where they pay off
Headless can make a store faster and more flexible. It also hands you a front end, a CMS and hosting to look after. Some merchants find they've lost the theme editor their marketing team relied on.
As a headless commerce development company, we recommend it only when the shopping experience truly needs it. We keep a content editor your team can use without a developer, and checkout and orders usually stay on Shopify or BigCommerce, where they already work well.
Migration
Migration and replatforming without losing traffic
Moving from Magento, Adobe Commerce, WooCommerce or an older custom platform is a big step. Most of the risk sits in the details, so our migration plan covers:
- 01URL mapping and 301 redirects, so search rankings carry over.
- 02Customer accounts, order history and saved payment methods where the provider allows.
- 03An app and integration inventory: what to rebuild, what to replace, what to drop.
- 04Product and customer data cleanup before the move.
- 05A launch plan with a rollback option.
Moving to Shopify rather than off it? See our Shopify migration services.
Integrations
Connected to the systems behind your store
A store is only as good as the data behind it. We connect your commerce platform to your ERP, CRM, PIM, order management, warehouse or 3PL, payment providers, tax and shipping services. Orders go to the ERP once. Stock, prices and order status come back without anyone retyping them. For multichannel stock, see our inventory management software development page.
Stack
Technologies we use
We pick the stack that fits the job and that another team could maintain later. Typical choices: Shopify and BigCommerce APIs and apps, Next.js and React for storefronts, Node.js, PHP/Laravel or Python for services, PostgreSQL, and AWS or Google Cloud for hosting.
Process
How a custom ecommerce development project runs
You see working software at each stage, and changes to scope or budget are agreed with you first. AI helps our developers write and test code faster. The quality of what we ship is still our responsibility.
- 01
Ceiling review
We look at your store, apps, rules and numbers, and tell you which of the three paths fits.
- 02
Discovery
We map pricing, checkout and order rules with your team and write a scope with agreed cost.
- 03
First release
We build the piece that hurts most, test it on real orders, and launch it.
- 04
Next stages
Further features follow in the order that pays back first.
- 05
Support
We monitor, fix and adapt the software as your business changes.
Cost
How much custom ecommerce development services cost
The price depends on which path you take, how many systems we connect and how much data moves. A custom app on top of Shopify is a much smaller project than a fully custom storefront and checkout.
After the ceiling review you get an estimate for your case, with scope and cost agreed before work starts. We also compare it with what you spend today on apps, plan fees and developer workarounds over three to five years.
After launch
Security and support after launch
We follow secure coding practices, keep card data with your payment provider, and set up access by role. After launch we monitor the store, fix issues, update dependencies and adapt features as your business grows.

FAQ
Custom ecommerce questions
What are custom ecommerce development services?
It's software built for your store's rules instead of a ready-made template. That can be one custom app on top of Shopify, a new storefront, or a fully custom commerce system.
How do we know we've outgrown Shopify or BigCommerce?
Look at your rules, not your revenue. If pricing, catalogs, checkout or order flow need constant workarounds, you've hit the ceiling. Large stores with simple rules can stay on Shopify for years.
Can we keep Shopify checkout and replace only what doesn't fit?
In many cases, yes. Custom apps and services run next to Shopify and handle pricing, configuration or order logic while checkout stays where it is. (Shopify Plus development)
How long does custom ecommerce development take?
A custom app often takes weeks. A headless storefront or fully custom commerce takes months and is delivered in stages, so you use parts of it early.
Will we lose SEO or customer accounts if we migrate?
Not when the move is planned. Redirects, data mapping and account migration are part of the project from day one. (Shopify migration services)
Is headless right for us?
Only if the front end is what holds you back. If the problem sits in pricing or order logic, headless adds work without fixing it.
Which integrations can you handle?
ERP, CRM, PIM, order management, warehouse and 3PL systems, payment, tax and shipping providers. We check each system's API during discovery.
What should we look for in a custom ecommerce development company?
Ask how they decide what to keep, how they handle migration risk, and who maintains the code later. With us, you own the code and documentation, and we can support it after launch.
How many apps does your store run on?
Send us your app list and the rules that cause trouble. We'll show you which parts need custom work and which can stay as they are.
