Integrations

API integrations. Let systems talk so the team stops copying.

ERP, CRM, ecommerce, logistics and the APIs you already use. Digitising a process is not buying another tool. It is making the ones you have work together.

How we work

01

The data contract is the design

What travels, when, what happens if it fails and who is the source of truth. Without that, the integration is a patch.

02

Ecommerce, ERP and CRM

Orders, stock, customers and invoices. Edge cases — returns, breakages, duplicates — are the real work.

03

Our own APIs when the product needs them

Sometimes you have to expose a service, not only consume someone else’s. API development with authentication, limits and usable documentation.

04

CRM and ERP

A data contract, not “connecting the API”.

05

Holded and WooCommerce

If Holded is the system, order, stock and invoice stay on the same flow. There is no published Holded case.

06

Verifactu and Facturae

On the order if the operation needs it. There is no published case.

07

PrestaShop REST API

Orders, stock, statuses.

Questions

Before you write to us.

What do you usually integrate?

ERPs, CRMs, payment gateways, logistics, email and the APIs your company already uses. We also build our own APIs when the product needs it.

Do you automate processes without touching the website?

Yes. Sometimes the work sits between systems, not in the interface. If the process is clear, it can be automated.

How do you integrate an API?

With a data contract and a flow. Not by pasting a key.

Can a CRM be integrated with an ERP?

Yes. There is no published case.

Do you integrate Verifactu or Facturae?

We integrate it if the operation needs it. There is no published case.

PrestaShop with ERP or REST API?

Yes.
