A first version that charges or validates
The initial slice includes the session that proves value and, when it is part of the model, the subscription flow.
Recurring product
SaaS development
SaaS products for teams that need to turn a repeatable service into software: account, permission, billing and a routine the customer comes back to.
The problem this service solves
A SaaS product is not a website with a login. It needs accounts, data isolation, billing, subscription states and a clear path to a useful first session. I help cut that first version and build the foundation without promising an infinite platform in month one. I am based in Porto Alegre, Rio Grande do Sul, and work remotely with companies across Brazil.
Benefits
Web, mobile or both
The channel follows the use: a web dashboard, an app or both, without duplicating rules unnecessarily.
Billing as a flow, not a detail
Payment, access and failure states are part of the design. In the Topotronics product, subscriptions use Asaas.
Evolution after launch
The foundation stays ready for new modules without restarting the product for every idea.
Deliverables
- Definition of the user, the account and the core session
- Access model and separation of customer data
- The agreed subscription or commercial validation flow
- Web interface and, if needed, a mobile app
- Error, failed-payment and first-access states
- A plan for what waits for later versions

FAQ
Do you build the whole SaaS alone?
I can take a first version live and evolve the product. If the scope needs a team, I join as the technical owner of a stream or define the slice that fits one specialist.
Which payment gateway do you use?
It depends on what the business already has. In Topotronics, recurring billing was integrated with Asaas. Other products can use the provider the company already contracted.
How long does a SaaS take?
There is no single timeline. A narrow first version can fit a few cycles; a platform with many roles cannot. The timeline comes from the scope, not from a generic table.
