CRMEUCRM, projects and invoicing in one system — built to be connected by developers, not dragged and dropped
Teamleader Focus keeps a company's contacts, deals, projects and invoices under one roof. Its connection interface is built for developers rather than a no-code toolbox, so we build the link to your other systems ourselves, or install one of the ready-made connections other companies have already published for other customers to use.
Before someone copies the client and deal details into an invoicing or warehouse tool by hand, often the next day.
After a built connection pushes the same record into that other system automatically, the moment the deal closes.
Before nobody knows whether a ready connection for that tool already exists, so the search starts from scratch.
After we check Teamleader's public catalog first — if another company has already published a connection for it, we use that instead of coding one from zero.
Before testing a new connection risks touching real client cards and orders while it's still unfinished.
After Teamleader can open a separate test account on request, so the connection is checked safely before it's switched on for live data.
Before a connection built years ago on the old interface quietly lost the ability to create or update records once Teamleader moved it into a read-only stage.
After we rebuild it on the current interface, so it creates, updates and deletes records fully again, and doesn't just stop working without warning when the old version is switched off for good.
For those who want to check: each point links to the official documentation page it comes from.
Teamleader Focus offers a public API built for developers and engineers comfortable writing custom-coded connections, rather than a no-code interface.

Source: support.focus.teamleader.eu ↗ checked 2026-09-25Before the full shutdown, API v1 went through an 'active deprecation' stage starting 1 June 2024, during which it could only read existing data — not create, update or delete it.

Source: support.focus.teamleader.eu ↗ checked 2026-09-25Teamleader doesn't offer a no-code automation builder — every connection is either a ready-made one from its public catalog or something built through its developer-facing API. The vendor's own documentation doesn't publish a numeric request-rate limit, so we size connections conservatively and watch for throttling in practice.
Three steps from a first message to work on your project.
Describe the task in the form — in text or by voice. Budget and timing are optional.
A developer studies the brief, asks about anything unclear and sends an estimate.
