Skip to all 2 articlesTwo decisions sink more SaaS products than any technology choice: building the wrong first version, and picking the wrong team to build it. The guides here address both.
Scope the first version so it can prove something
The SaaS product development guide covers the path from idea to a subscription product, and the guide to building an MVP argues the point most first-time founders miss: an MVP is defined by the question it answers, not the features it contains. Rorix ships production SaaS MVPs on a 12-week schedule; the SaaS development page shows how that engagement runs.
Choose an agency that has shipped subscription software
Agency selection for SaaS differs from generic outsourcing because multi-tenancy, billing, and upgrade paths punish inexperience. The SaaS development agency comparison evaluates the field, and the guide to choosing a custom software development company gives the vetting questions that expose a portfolio built on brochure sites.

SaaS development FAQ
How long does it take to build a SaaS MVP?
About 6 weeks for a lean validation build, about 12 weeks for a production SaaS MVP, and 4 months is a reasonable outer bound. Timelines stretch when the first version tries to answer several questions at once instead of one.
How much does an MVP cost?
Most MVPs run $20,000 to $75,000 depending on scope, integrations, and how much polish the core loop needs. The figure buys an experiment that can produce a conclusion, not a finished product.
What features belong in a SaaS MVP?
The ones the experiment cannot run without: authentication, data integrity, a fast core loop, instrumentation, and enough polish that the interface is not the variable being tested. Cut anything that limits what the product can do, never anything that limits what you can conclude.
