CRM and ERP integration.

We build the interfaces between shop, CRM, and ERP so they agree on every order, product, and customer: explicit mappings, sync rules, retries, logs, and one system of record per entity. For example WooCommerce with Billbee, and a webshop with HubSpot.

Line drawing: a laptop shop, a phone with a customer profile, and a server joined through one sync hub

Live demo

Watch an AI agent at work.

A supplier invoice arrives by email. The agent does the rest: through the interfaces of the ERP and PIM, and where there is none, it clicks through the program like a person.

Sample with invented data. This is how the agents we build into ERP, PIM, and CRM work.

This workflow for your company

How the demo runs: a supplier invoice arrives by email. The AI agent reads the amount, due date, and items from the PDF. In the ERP it books the invoice through the interface, without a single click. In the PIM it updates the purchase price, also through the interface. The tax adviser's portal has no interface: the agent opens it, uploads the receipt, and fills in the fields like a person. Before submitting, it waits for the team's approval.

Questions on cost, time, and delivery.

What does an ERP interface cost?

€6k to €45k, as a fixed price. The connection itself is rarely the expensive part; the work around it is: mapping, duplicates, failure cases, and deciding which system is right.

How long does a CRM-ERP integration take?

3 to 12 weeks, depending on the number of systems and records and on whether historic data gets backfilled (from €2.5k).

Which systems do you connect?

We have connected WooCommerce with Billbee and a webshop with HubSpot, among others. Any system with an API, webhooks, or a clean file export can be connected; before the proposal we check what the API actually delivers.

What happens when a sync fails?

The record lands in an error queue instead of disappearing. Partial syncs can be recovered, every failure shows up in the log, and an alert fires when a system stops answering.

Are there not ready-made connectors for this?

For simple cases, yes, and then we recommend them. It becomes custom work when fields do not map one to one, data flows in both directions, or a failure costs orders.

Can an AI agent work inside the ERP?

Yes, through the same interfaces: it reads orders, creates records, and answers requests with data from the ERP. Whether that runs over an MCP server or the API directly depends on the ERP.
