Spain is often seen as a difficult place to build SaaS. My experience has been different. If you understand the rules and design your systems correctly, Spain can be a very strong base to grow from.

Bootstrapping shaped my mindset, my decision-making, and my leadership. It pushed me to think long term, to build solid foundations, and to treat operational discipline as a competitive advantage.

I have seen venture-backed companies move very fast in the beginning, only to slow down later because they accumulated compliance debt. Fixing tax and invoicing issues once the company is already scaling is far more expensive than doing it right early on.

When you bootstrap, you cannot afford vague processes or “we’ll fix it later” thinking. Every decision has consequences. That pressure forces better systems from the start. You design operations and compliance to work properly because you do not have the luxury of throwing money at the problem later

The SaaS companies that scale internationally without constant friction are not the ones that ignore compliance. They’re the ones who plan for it early.

Despite what some people think, compliance-first SaaS scales faster 🚀

When tax logic and e-invoicing are built properly from the start, they stop being a burden. They become a source of confidence for founders, for customers, and for partners.

I’ve seen SaaS companies grow fast only to slow down later because their invoicing and tax setup wasn’t designed for multiple countries, different VAT rules, or regulatory changes. Fixing that after the fact is expensive, stressful, and risky.

Taxes and e-invoicing are not paperwork. They are infrastructure. And just like bad technical architecture, bad tax architecture doesn’t fail immediately; it fails when you try to scale.

Sí, me pasé hace un año. La uso simplemente para guardar mi lista de pendientes y registrar los ya leídos. Está muy bien.

Por la misma razón por la que otros nos mudamos a Fable: fable.co. Para intentar no compartirlo todo con Amazon, que ya bastantes datos tienen.

Para colmo, los autónomos, que son los que más se han quejado, tenían de plazo hasta julio. Pero en lugar de explicarlo bien, han decidido alargar la agonía un año más. ¿O alguno piensa que los que no han hecho nada hasta ahora van a tenerlo todo listo antes de 2027?

La paradoja es que todos los fabricantes están preparados desde julio y los usuarios de programas de facturación solo tenían que subir su certificado y hacer clic en un botón para activar el nuevo sistema. Ese era todo el esfuerzo que había que hacer.

Factura tienes que hacer siempre. La diferencia es que tus precios finales pueden ser más competitivos porque no tienes que repercutir IVA.

Como dice David, en profesiones donde no tienes que hacer mucha inversión y no tienes muchos gastos, te puede compensar durante los primeros años.

Chatty is right (this time) ☺️

Pero tampoco te podrías desgravar el IVA de tus gastos empresariales. No te devolverían el IVA en todos los gastos que tienes en la TRG.

En Canarias tenemos una franquicia fiscal de 30000 € desde hace años y no compensa si tu actividad tiene muchos gastos.
