Developer-built, not no-code glue
We write integrations in code with clean architecture (DDD), idempotency and tests. You get maintainable software and the diagrams, not a connector that breaks on the next platform update.
About
A small studio that actually builds it.
Francodesystems is a developer-first studio building custom integrations between the systems businesses run on. No account managers, no black boxes: you talk to the people who write the code.
Fixed price, no endless discovery
A 30-minute diagnostic, then scope, timeline and a fixed price in writing. What you see is what you pay.
We open-source what we can
Our n8n community node for Holded (42 resources, 323 operations) is MIT-licensed on npm and verified by n8n. We would rather earn trust in public than hide behind a sales deck.
ERP-agnostic
QuickBooks, Xero, Odoo, NetSuite, Holded. We connect the tools you already run instead of pushing you onto one platform we happen to resell.
Who you work with
Juan Cantón Rodríguez
Founder and lead developer. Builds integrations with security and reliability in mind from day one: idempotency under concurrency, cursor pagination, structured errors, queues and observability. Maintains the open-source n8n node for Holded and writes about the API and integration traps on the blog and on dev.to.
Let's talk about your stack.
30 minutes, no strings. We map what you have, what is missing and what it costs to connect it properly.
