The Billin experience has already
left a public trail.
These quotes and patterns come from the sources indicated. They are shown with context and a link so you can check the full origin.
- 01 Trustpilot ES · Billin “The software leaves hundreds of sales in draft without sending them to the Tax Agency, and when you ask the human team for help they don't offer solutions.”
- 02 Trustpilot ES · Billin “The platform has gotten worse over the last few years. After the interface change you need a lot of patience, it's one glitch after another. I spent half an hour trying to issue an invoice that's impossible to get out of draft.”
- 03 Trustpilot ES · Billin (post-TeamSystem) “They removed the ability to contact customer support via chat, so much for personalized support.”
- 04 Trustpilot ES · Billin “They make it very hard to leave — you can't properly export contacts or invoices to take them to another provider.”
The difference shows when you
compare the whole job.
It is not enough that a feature exists. What matters is its scope, the context it keeps and what happens before and after.

Before switching from Billin.
Answers on scope, data, prices and continuity before you decide.
See migration from Billin →What exactly are these zombie invoices?
There are recurring reviews on Trustpilot from Billin users saying their TicketBAI invoices (Basque regional tax authority) stay in draft status and never actually get sent. The user believes they've been issued until the quarterly filing doesn't add up months later. Cofactu detects any invoice stuck pending >24h and alerts you by email + in-app + banner. Public commitment at /seguridad.
The Shopify refund issue sounds serious, right?
Yes. If you sell on Shopify and a customer returns an item, Billin sends the original sale to the tax authority but does NOT send the corrective invoice. The VAT stays as if you'd collected it, so you overpay VAT without knowing it. Cofactu sends the corrective invoice automatically when it receives the refund webhook.
Why do you insist so much on human chat?
Because the day AEAT rejects an invoice on a Friday at 6pm, what you need is a person, not a ticket in a queue. Billin removed it after the TeamSystem acquisition in 2023 (complaint documented on Trustpilot). At Cofactu there are people by WhatsApp and email on every plan, with first-response times written into clause 8 of the terms.
Is migrating from Billin complicated?
Trustpilot reviews say Billin "makes it hard to leave." Even so, you export what you can (CSV of clients and invoices via their panel) and upload it at /migrar/desde-billin. If your data got locked or you can't export, email us at hola@cofactu.com — we have documented workarounds.
