We automate the repetitive work in your accounting practice.Our termsIYou see the savings first.IIOnly then do you pay.

Crownlark is a focused engineering studio for UK accounting and bookkeeping practices. First we learn how your team works. Then we build a system for your firm alone and test it on your real client work. Your team keeps the reviews and the sign-offs.

“Most software is paid for before it works. Ours is paid for after.”

We build the system, run it on your real work, and measure the time and money it saves. You pay only after you have seen it.

A small studio,
by design.

Deliberate scale ensures institutional focus, direct accountability, and craft excellence.

We take on a limited number of UK practices at any one time. There are no account managers, no junior associates, and no offshore handoffs. When you partner with Crownlark, you collaborate directly with the engineer who designs and writes your system. We intentionally remain small so that every firm receives our undivided focus.

“We build around the way your firm already works.”

I started Crownlark because UK accounting practices run on hard-won expertise. Most software tries to squeeze that expertise into a fixed template. We do the opposite. We build around the way your firm already works. And we only ask to be paid once you have seen the saving yourself.

The work we look for

We don't arrive with a product. We find the work in your firm that fits these four signs.

01

IT REPEATS

It comes back every week, month or year end.

02

IT FOLLOWS RULES

Your team already knows the steps by heart.

03

IT TAKES HOURS

It eats time that could go to client work.

04

IT NEEDS NO EXPERT JUDGEMENT

A qualified person does it, but doesn't need to.

How it works

Four steps. You pay only after the last one.

GATE IOBSERVATION

We learn your work

We sit with your team and see how the work really gets done, odd cases included, before we write any code.

Phase Alpha
GATE IISYNTHESIS

We design your system

We design it around the software you already use and the quality checks you already have.

Phase Beta
GATE IIIVALIDATION

We run it alongside you

The system runs next to your normal process on real work. Your team works as usual while we check every result.

Phase Gamma
GATE IVHANDOVER

You see the proof, then you pay

We show you the time and money it saved on real work. Your team checks it. Once they agree it works, you pay and we hand it over.

Retrospective Proof
