SaaS product development, from MVP to a platform that scales

Building a SaaS product needs more than screens: accounts for many customers, roles and permissions, secure data separation and a clean path to growth. SimpleApp is a SaaS and MVP software development company that takes your idea through MVP to a secure multi-tenant platform, including B2B SaaS application development with accounts, roles and a billing-ready structure. We have built Site360, an AI-powered product catalog and commerce-sync platform for online stores.

FAQ

SaaS Product Development questions

How long does it take to build a SaaS MVP?

A focused MVP is typically built in phases, with a usable first release early. We give a firm timeline after the discovery stage, once the scope is clear.

Can you build ecommerce product management (PIM) software?

Yes. Site360, our own product catalog and commerce-sync platform, covers variants, categories, media, version history and AI-assisted descriptions, and we can build something similar around your needs.

Do you build B2B SaaS applications?

Yes. B2B SaaS needs customer accounts with several users, roles and permissions, secure separation of each customer's data and an admin area for your team. We design these from the start, so the product is ready to grow instead of being rebuilt later.

Are you an MVP software development company?

Yes. We help founders launch a focused first version quickly: a clear scope, the few features that prove the idea, and a clean base to build on once real users give feedback. You own all the source code.
