Custom SaaS product development

Custom SaaS from ANTLR Tech is a SaaS product built around your domain — tenancy, billing, roles and roadmap — owned by you, not rented from a generic app builder. It is built for your operation rather than configured from a product, so the screens follow the way your team already works. Companies packaging a workflow for their industry or their own franchise network.

It depends on scope, integrations and how many locations you run — so we don't publish a number that would be wrong for most people. What we do commit to is the shape: a short paid discovery, then a fixed price for a defined first release that you approve before any production code is written. No open-ended billing, and no surprise at the end.

A first working release lands in 6–14 weeks from kickoff. We run two-week cycles with a demo at the end of each, so your team is using part of the system while the rest is still being built — rather than waiting for a single reveal at the end.

Operators and founders ready to productise how they work. Companies packaging a workflow for their industry or their own franchise network. If an off-the-shelf product already fits without workarounds, we will say so — custom software only pays when the process is specific enough that rented tools fight you.

No. Custom SaaS from ANTLR Tech is built around how your team already works, then replaces the spreadsheets and disconnected apps holding that process together. You are not configuring someone else's product to fit — the screens follow your steps, your terminology and your exceptions.

Yes. Accounting, payments, email and the systems you intend to keep stay connected rather than being replaced for the sake of it. Anything with an API is in scope, and we agree the integration list during planning so nothing surfaces as a surprise mid-build.

You do. The repository, the hosting accounts and the data are yours from day one, documented at handover so another team could pick it up. There is no seat licence, and no fee that exists only to keep you with us.

One workflow your team runs daily. We deliberately scope the first release to the narrowest slice that removes real manual work, because a narrow release in production teaches us more than a wide one still sitting in staging. The rest follows once it is earning its keep.

No. Most clients arrive with a problem rather than a spec. Deciding what to build first — and what to leave alone — is the work of the discovery stage, and you keep the process map that comes out of it either way.

Usually, yes. We migrate historical records, run both systems in parallel for one cycle, and cut over only once your team confirms the new one is faster for daily work. Nothing is switched off before that point.
