E-commerce & Transactional Platforms: the overview

Off-the-shelf stores work well until your business doesn’t fit the template: complex pricing, B2B accounts and approvals, custom order workflows, unusual products, or tight integration with your operations. A custom e-commerce or transactional platform is built around how you actually sell, not around a theme’s limitations.

We build the catalog, pricing rules, checkout and account experience your customers need, and connect it to your inventory, payments and back office so an order updates stock, finance and fulfilment without re-entry. Customers, trade buyers, your staff and your admins each get the permissions their role needs. Whether it’s retail, B2B trade ordering, subscriptions or a marketplace, the platform fits your model.

The result is a store that works the way your business does, with less friction for buyers and fewer workarounds for your team. Because it is custom, you control the roadmap and the data, with no platform revenue share; payment providers still charge their own processing fees.

Illustrative example

Is e-commerce platform development the right choice?

A good fit when

  • Customer-specific pricing, credit terms, quotes or approval steps that a standard store cannot handle without heavy plug-ins.
  • Orders must flow into an ERP, inventory or fulfilment system as they happen.
  • Your product model is unusual: configurable products, bundles, made-to-order or restricted items.
  • Trade customers need accounts with several buyers, order approval and reordering.

Consider another option when

  • A standard retail catalog with a normal checkout. Shopify, WooCommerce or a similar platform is usually faster to launch and simpler to run.
  • You are not yet sure about demand. Test with a hosted store first and build custom once the rules that do not fit are clear.
  • Your main need is stock and accounting rather than online selling; see inventory and accounting systems.

Usually in a first release

  • Catalog, variants and your core pricing rules
  • Cart, checkout, tax and shipping rules for your main markets
  • One payment gateway, order confirmation emails and an order admin area
  • Customer accounts with order history and reorder
  • Integration with one inventory or ERP system for stock and orders

Outside the first release unless agreed

  • Multi-vendor marketplace features, seller payouts or affiliate programs, unless agreed
  • Additional currencies, languages, payment methods or shipping carriers beyond those agreed
  • Product photography, copywriting and catalog data entry
  • Marketing campaigns, paid advertising and ongoing search optimization

Anything outside the approved scope is reviewed and agreed before work begins. See how we work.

Data, controls, responsibilities and ownership

Data migration and integrations

  • Payments need a payment gateway and merchant account opened in your name. Approval, fees, payout timing and any reserve are set by the provider.
  • Card data is captured by the gateway’s hosted fields or checkout, which keeps card details off your servers and narrows your PCI DSS scope. Your PCI obligations remain yours to confirm with your provider.
  • Stock, prices and orders sync with your ERP or inventory system through its API or a scheduled exchange. We agree which system is the master for each field and how often it syncs.
  • Product data is migrated from an existing store or spreadsheet, with redirects from old product URLs where you have search traffic to protect.
  • Tax and shipping calculation may use a third-party service, which brings its own account, terms and fees.

Roles, approvals and audit

Customer and buyer roles
Trade accounts can have several buyers, with spending limits and an approver before an order is placed.
Staff and admin roles
Separate permissions for catalog editing, pricing, order handling and refunds.
Price and refund controls
Price changes and refunds above a threshold need approval and are logged.
Audit log
Order status changes, payments, refunds and admin edits are recorded with who and when.

What we need from your team

  • Product data, images and descriptions, and your pricing and discount rules.
  • Merchant account, tax registration details and shipping carrier accounts in your name.
  • API or export access to your ERP or inventory system.
  • Terms of sale, returns policy and privacy notice for the storefront.
  • Test orders across payment, shipping and refund scenarios during acceptance testing.

Ownership, support and running costs

  • Project source code, designs and documentation transfer to you on full payment, and your data is yours throughout; see our IP and ownership policy.
  • Hosting, domain, database and third-party service accounts (email, SMS, payment gateway) are set up in your name or transferred into it, so the system does not depend on accounts we hold.
  • Running costs by category: hosting and content delivery, payment processing fees charged by the provider, tax or shipping services where used, email sending, monitoring and backups, and an optional support agreement. Amounts depend on order volume and providers.
  • Support after launch (security patches, dependency updates and small fixes) is agreed separately; see software maintenance and support and our support SLAs.

FAQ

E-commerce & Transactional Platforms FAQ

Platforms like Shopify and WooCommerce are excellent for standard stores and are often the better choice. A custom platform makes sense when your pricing, B2B workflows, product model or operations integration don’t fit a template without heavy, fragile customization, or when you want the whole system under your control.

Yes. Account-based pricing, credit terms, approval workflows and reordering are common requirements in transactional platforms, and they are where generic stores tend to struggle.

Usually, yes. We integrate the platform with your inventory, ERP and fulfilment systems through their APIs or scheduled exchanges, so orders update stock and operations without re-entry. How often data syncs depends on what each system supports.

Through a payment gateway such as Stripe or your bank’s gateway, using its hosted payment fields or checkout, so card details go to the gateway rather than your servers. The merchant account is opened in your name, and its approval, fees and payouts are set by the provider. PCI DSS obligations remain yours, and the gateway approach keeps that scope smaller.

We treat page speed, clean URLs, structured data and crawlable pages as requirements and test them before launch, since performance affects both buyers and search visibility. Rankings also depend on content, competition and links, so no build can guarantee them.

Project source code, designs and documentation transfer to you on full payment, and your data is yours from day one. Hosting and third-party accounts sit in your name, with no revenue share or per-transaction fees from us beyond the payment provider’s own charges. Open-source components stay under their own licences, as our IP and ownership policy sets out.
