Micro SaaS DevelopmentWe build micro SaaS
that does one thing well
and charges for it.
A micro SaaS is small on purpose — one sharp feature, one clear audience, real billing from day one. We build lean subscription products fast, with the money layer done properly, owned by you. The discipline of doing one thing well is the whole point.

What we buildSmall, sharp,
and charging.
Micro SaaS keeps the scope tight and the billing real. We build the lean product that starts earning fast.
01
One thing, done well
A tight, focused feature set — the strength of a micro SaaS, not a limit.
02
Real billing from day one
Subscriptions on Stripe, because charging is the whole point.
03
Cheap to run
Lean by design, so it stays viable for a solo founder or small team.
04
Fast to launch
Small scope means live and charging in weeks, not quarters.
05
Owned by you
The full codebase and billing, no platform lock-in.
Small is the strategy, not a compromise
Micro SaaS inverts the usual instinct to build big. Instead of a sprawling platform that tries to do everything, a micro SaaS does one specific thing, for one specific audience, better than any bloated all-in-one tool bothers to. That narrowness is not a limitation you settle for — it is the strategy. A sharp, focused product is easier to build, cheaper to run, simpler to explain, and far easier for a small team to support.
This makes micro SaaS a genuinely strong first move, especially for a solo founder or a small team. You are not betting a huge budget on a big vision before you know it works. You are building the smallest real, chargeable product that solves one clear problem, getting it in front of paying customers fast, and letting revenue rather than guesswork tell you what to do next.
We build to that philosophy. We will actively resist scope creep on your behalf, because the thing that kills micro SaaS is the same thing it is meant to avoid: quietly growing into the bloated tool it was supposed to beat.
Still real SaaSSmall scope, but the billing is never optional
The one place a micro SaaS is never allowed to be small is the money. Keeping the feature set tight is the whole idea; skipping real billing is not, because billing is precisely what makes it SaaS rather than a free tool nobody pays for. So even the leanest micro SaaS we build has proper subscription billing from day one — plans, sign-up, payment, and the account states around it, on Stripe.
This matters more for micro SaaS than almost anything, because the entire premise is a small product that charges cleanly and reliably. If the billing is flaky, the model is broken — there is no big enterprise contract to fall back on, just lots of small subscriptions that need to work every time. We build that money layer properly regardless of how small the rest of the product is.
We do this from the experience of running our own billing in production, so the real-world subscription edge cases are handled rather than discovered live by your first paying customers.
ProofWe ship lean products with real billing
The relevant proof for micro SaaS is that we build and run subscription software with real billing ourselves. sellyourboat.io is a Wall & Fifth venture that includes subscription software we built and operate, with Stripe billing in production and the account and payment machinery a paying product needs.
We are comfortable building lean and shipping fast without cutting the corner that matters — the ability to charge. That combination, small scope plus solid billing, is exactly what a micro SaaS lives on, and it is how we work by default.
We have also delivered payments work across our client roster including KompiPay. Building small, chargeable products properly is squarely in what we do.
The buildProduction stack, fixed price, owned outright
We build micro SaaS on the same real production stack as everything else — Next.js, React, TypeScript, PostgreSQL, Stripe for billing, deployed properly — just scoped tight. Small does not mean flimsy; it means focused. The product is lean, but it is real software you own, not a no-code assembly you rent.
We work to a fixed price. From 16,000 GBP for a focused micro SaaS — one core feature, accounts, and real billing, which is often the whole product by design — and from 30,000 GBP if you want a few connected features and integrations. Payment processing and any third-party usage is passed through at cost, never marked up.
And you own all of it: the full codebase, the billing setup, the infrastructure, handed over on delivery. No platform you keep paying, no licensing, no lock-in. Yours to run, change, and grow with us or any team you choose.
