Fixed scope. Milestone billing.
You own the code.
Prensivo is a custom software development studio. We build client portals, internal tools and AI-native systems for growth-stage businesses, at a fixed price, with code you own.
Every engagement starts with a written scope and one number. No hourly billing, ever.
You receive: Problem brief
One focused call. We map the real problem (the manual process, the spreadsheet, the handoff that keeps failing) instead of collecting a feature wishlist.
You receive: Scope + price
One number, one written scope, one milestone schedule. Anything outside scope becomes an agreed change order, never a surprise invoice.
You receive: Live staging
You get a live staging link at every milestone and see working software before the next payment is due. No long silences.
You receive: Handover + code
Launch, handover walkthrough and full code ownership. Ongoing care is available as a monthly retainer, and never required.
Software that runs your business comes first. Websites and AI automation come when they solve a real problem.
Client portals, internal tools, dashboards and backends, designed around how your team actually works, with AI features built in where they earn their place.
Custom-built sites and storefronts for businesses that have outgrown templates. Fast, accessible and built to convert, not just to look good.
Once a system is live, we extend it with intake triage, document summarisation, support agents and reporting automation, added to software that already works.
Maintenance, monitoring, security updates and a monthly bucket of new features, so your software keeps improving after launch.
Proven, boring-in-a-good-way tools. Grab the row and throw it.

Prensivo Labs
The problems we see repeat across client work become the subscription software we build next. Join the list to shape what comes first.
Hourly billing rewards the vendor for taking longer. A fixed price forces us to scope carefully and own the outcome, which is exactly what you want from a build partner.
Anything outside the written scope becomes a change order with its own price and timeline, agreed before work begins. You always know the number first.
You do. Once the final milestone is paid, the code, repositories, designs and accounts are transferred to you. There is no lock-in.
Our focus is established, revenue-generating businesses with real processes to improve. If you are pre-revenue, we may be honest that a smaller scope or a different partner fits better.
A deposit before work starts, then milestone payments as working software is delivered. Core builds are typically 40% / 30% / 30%. We invoice in USD.
