The short answer
A SaaS architecture review is a written health check of how your software is built. It looks at things like whether one customer can see another's data, who is allowed to do what, how fast the product runs, and how it is set up in the cloud. It ranks each problem as fix now, plan next or keep an eye on, and says what to do about it.
A health check
A written report on how your software is built.
Six areas
Data, access, speed, backend, cloud, code health.
Ranked in plain words
Fix now, plan next, keep an eye on.
When you need one
Most teams ask for a review when one of these starts to hurt.
Things are getting slower
Pages, reports or searches take longer as you add customers and data.
Every change breaks something
Releases feel risky and the team slows down.
Your cloud bill keeps climbing
Costs grow faster than your customer count.
A bigger customer is coming
They will ask about data separation, access rules and security.
You are about to build something big
You want to know the base is solid first.
Your AI feature is not ready
It works in a demo, but is slow, costly or unreliable with real customers.

Common questions
What is a SaaS architecture review?
A SaaS architecture review is a written health check of how a software product is built. It finds what could break as the product grows, ranks each problem by urgency, and says what to fix first.
When should a SaaS company get an architecture review?
Get one when pages or reports are getting slower, every change breaks something, your cloud bill is rising faster than your customers, you are about to take on a large customer, or before you build something big on top of what you have.
How long does an architecture review take?
It depends on the size of the product and what we agree to look at. We agree the scope before starting, so you know what you are getting.
What is the difference between an architecture review and a code review?
A code review checks individual changes for mistakes. An architecture review looks at the whole design: how data is kept apart, how access is controlled, how the system handles growth, and how it is set up in the cloud.
Will you tell us to rebuild everything?
Not by default. Most reports say what to keep, what to change and what to leave alone. A rebuild is only suggested when the evidence clearly shows it is the cheaper option.
Do you work with companies outside Chennai and Coimbatore?
Yes. Tenlyr works with product teams across India and overseas, mostly by video call and shared documents.
