We started by solving one restaurant's problem

Tenzan was born from a concrete problem: a restaurant in Rio de Janeiro needed a POS that worked the way it did. We built it to measure.

When that POS had to issue invoices, we found the options on the market didn't fit, so we wrote our own fiscal engine. Today there are two products: TenzanPDV, which started the company, and TenzanNFE, born from what it needed.

Customer in operation · Rio de Janeiro

Our first customer has been running on Tenzan since 2025. The POS runs at their counter every day, and the fiscal engine issues the invoices for that operation.

What we build

Two products, one foundation: in-house engineering and a commitment to those who rely on us every day.
