A SaaS app is the product you charge for, the thing customers log into, pay for and come back to. We design the product, wire the billing and seats, and build the dashboard they actually work in, so you ship a business rather than a brochure with a login. After launch we keep the loop open: usage tells us what to change next.
What is a SaaS app?
Software somebody pays for on a recurring basis and logs into to do a job. That is the whole definition, and every hard part of building one follows from its two halves: it has to keep being worth the next payment, and it has to hold more than one customer's data without ever confusing them.
Which is why a SaaS product is not a website with a login bolted on. Accounts, roles, tenancy, billing, seats, trials, upgrades, failed payments, audit — none of it is the feature you are selling, all of it has to work before anyone can buy, and each one is a place where a shortcut becomes a rebuild.
We build the product and the business machinery around it in the same pass, then stay long enough to read what usage says. The first version is a hypothesis. The interesting work is the six months after launch, when you can finally see which parts people open.
What we do for you
The product, and the parts of a software business that are not the product.
Data model, tenancy boundaries, and the decisions that are expensive to reverse. Getting the tenancy line wrong is the one mistake that surfaces as a rewrite rather than a refactor.
Sign-up, SSO, invitations, per-seat permissions, and the admin who has to fix things without a developer. Permission models are easy to add and very hard to change once customers depend on them.
Plans, trials, proration, upgrades, failed payments, and the invoices your accountant will ask for. Billing is where most self-built SaaS quietly loses money — not to fraud, to edge cases nobody handled.
The screens customers open every day, designed for repetition rather than for a demo. A dashboard optimised for the first five minutes is exhausting by week two.
A documented API, webhooks, and connections into the tools your customers already run. Integration is frequently the actual purchasing decision.
Search, summarisation, extraction, assistance — added where it removes work a person is doing today, not because the category expects a sparkle icon.
How a build runs
Twelve to twenty weeks to a paying first version, depending on the domain. After that, a release cadence rather than a finish line.
Who pays, what for, and what changes when they stop. Pricing is a product decision and it constrains the data model, so it comes first rather than last.
How customers are separated, where that boundary is enforced, and what an admin can see across it. Written down and reviewed before the first table exists.
Accounts, roles, billing, the shell. Unglamorous and blocking — nothing can be sold until all of it works, so none of it is a later problem.
The thing you are actually selling, in vertical slices that each reach something usable. A slice that cannot be demoed is a slice that cannot be corrected.
Analytics, error tracking and usage events on the paths that matter, wired before launch rather than during the first confusing week after it.
What people open, what they abandon, where they invite a colleague. The roadmap after launch should mostly be answers to those, not the backlog written before anyone had used it.
Why it matters
The distance between shipping software and running a software business is mostly the parts that are not features.
A subscription is a business model, not a payment method. Built properly it compounds; built as an afterthought it churns in ways you cannot diagnose.
One customer seeing another's data is the failure a SaaS does not recover from. Enforcing that at the boundary rather than in each query is the difference between a policy and a hope.
Self-serve sign-up, invitations and in-product upgrades mean customers arrive while everyone is asleep. Every manual step in that path is a ceiling.
Most buyers are not replacing nothing — they are adding to a stack. An API and two good integrations remove the biggest objection in the room.
Query patterns that are fine with ten accounts are not fine with ten thousand. Designing for the second costs almost nothing up front and cannot be added cheaply later.
Typed, tested, documented, and deployed by a pipeline rather than by a person. We build assuming we will not be the last people in here.
Where this has already shipped.
Next step
Tell us what people are paying you to do by hand.
That is usually where the product is. Send us the shape of it and we will come back with a scope, a range, and the parts we would argue about.
