About

A small team in Thanh Hóa, building for accountants.

Banana Software started with one painful problem: downloading tax documents one file at a time.

We automated it, then kept going. Today our tools handle e-invoices and tax declarations for businesses across Vietnam. The next chapter is a full accounting suite — so the documents our tools capture become the books you close at month-end, without re-typing anything.
