Fixed-price packages for mid-sized eCommerce

Four focused packages with a clear scope and transparent "from" prices. Every one starts with a free 30-minute discovery call and ends with a documented result your team can own.

Integrations & APIs

Systems. Finally in sync.

API & Integration Engineering

from5.000 €

fixed price

Clean APIs between shop, ERP, inventory, shipping and third-party systems. When your systems no longer talk to each other cleanly, growth stalls. I build the missing bridges — clean, documented, future-proof, ready to hand over.

Built for shops and B2B platforms whose backend systems have fallen out of sync — or who work with a shop agency that doesn't cover backend integration.

What's included

  • REST or GraphQL API for one integration
  • Connection to one system of your choice (ERP, inventory, accounting or shipping)
  • Full documentation for your team or agency

Fulfillment & OMS

Your processes. Your workflow.

Custom Fulfillment & Order Management

from8.000 €

fixed price

I build fulfillment and order-management systems that match your actual processes — instead of standard tools you have to squeeze yourself into. Ideal for multi-channel sales, complex warehouse logic or grown shipping structures.

Built for shops with complex order, shipping or marketplace requirements that off-the-shelf tools can't cover.

What's included

  • Order routing across channels and marketplaces
  • Stock and inventory synchronisation
  • Shipping integration for one carrier
  • Clean handover to accounting

Product data & PIM

One source. Every channel.

Product API & PIM Backend

from6.000 €

fixed price

One central source for your products — and clean output to every channel. I build product APIs and PIM backends that feed your shop, marketplaces, ERP and marketing tools at the same time — without duplicate data work.

Built for manufacturers, wholesalers and brands with larger catalogs whose product data lives in multiple systems or has to be maintained in parallel today.

What's included

  • Central product data model, cleanly structured
  • APIs for multi-channel distribution
  • Optional AI enrichment (e.g. classification, translation)

Tailored + AI

Your process. My solution.

Custom Tools & Backend AI

On request

fixed price

What your standard software can't do, I build. Tailored internal tools, integrations, reports — with optional AI integration in the backend (mail processing, enquiry pre-qualification, intelligent routing, classification).

Built for companies with concrete process pains who can't move forward without a development team — or who want to deploy AI in the backend deliberately, without buzzword demos.

What's included

  • Clean requirements clarification in the discovery call
  • Fixed-price proposal after scope definition
  • Pragmatic implementation, documented and handed over
  • Optional AI building blocks where they actually take work off the team
