“
I have several sources of income, and before, everyone handled their own part — it was a mess trying to figure out whether I was paying too much or too little. With Fintax, someone finally sees it all together. And when something comes up, they reply directly to me, not to a support ticket.

My experience with Fintax has been excellent over these five years. I have received consistent follow-up and high-quality advice. They are always available to answer any questions or provide the support I need, which gives me great peace of mind. I highly recommend them with complete confidence.

Between projects, clients and construction work, I didn't have the headspace to keep my accounting up to date, and I'd missed a couple of obligations without realizing it. Fintax brought me up to date, and now they let me know before something is due, not afterward.

“
My work makes me demanding when it comes to numbers, and what I value most about Fintax is that they explain why things happen, not just what happens. When I had a discrepancy with a withholding, they found it and corrected it before it became a problem with SAT.

We came from a firm that charged us as if we were a big company and treated us as if we were tiny. With Fintax, it's the other way around: we pay a fair price for our size, and they pay attention when something is urgent. We've been with them for about a year and a half, and we haven't had a single surprise with SAT.

“
I used to use one of those automatic invoicing apps. It worked while everything was normal, but as soon as I received a request from SAT, I didn't even know whom to ask — there's nobody on the other side of the app. With Fintax, I talk to my accountant on WhatsApp, and that's it, resolved.

I switched from a traditional firm because every process took weeks, and I never knew where things stood. With Fintax, I can see the progress, and they reply quickly — it feels like having an accountant right inside my office, instead of sending things into a black box.

We received an invitation letter from SAT that had us worried, thinking a fine was inevitable. The Fintax team took charge, we resolved it without a penalty, and I learned that these things can be prevented if someone is really keeping an eye on your situation all the time.
