Integrations & APIs

Finance, payments, shipping, and CRM that talk to each other. So you stop typing the same thing twice.

Every time data is typed in twice, you have both wasted time and a source of errors. Integrations remove the duplicate work: orders that land in your accounting system by themselves, stock counts that match, and shipping labels generated automatically.

I have built integrations for e-conomic, Dinero, Uniconta, Stripe, Quickpay, MobilePay, and GLS among others — and I develop APIs, webhooks, and custom middleware when no standard connector exists.

You get a solution with proper error handling and logging, so you can see what happened if something ever misbehaves. Integrations you cannot debug are not integrations — they are scheduled problems.

From enquiry to finished product

A fixed process that gives you clarity and confidence from the first email.

  1. You contact me with a short description of the task.
  2. We hold a short online meeting to align needs and direction.
  3. I prepare an SOW (Statement of Work) with a concrete quote.
  4. We review it together and adjust if anything is missing.
  5. You accept the final quote.
  6. 20% of the quoted price is paid, and work begins per the SOW.
