From idea to a SaaS that scales
We build SaaS products end to end — subscription billing, multi-tenant architecture and cloud scaling included. And we learned it by building our own SaaS.
Building a SaaS is more than writing code
SaaS is the hardest kind of software: one codebase must serve hundreds of customers, take payments automatically, manage user roles, run without downtime and get cheaper as it grows. The wrong architecture collapses at the first hundred customers.
Postersoft is a team that builds and operates its own SaaS products — Paymenu, galeri, rehber and Tezgah. So our decisions aren't theoretical but field-tested: where to add multi-tenancy, where to queue, when to cache.
Whether you're a startup at the idea stage or a company looking to turn existing software into SaaS, we become your technical partner across the whole journey — from MVP to scale.

SaaS development FAQs
