Nadia’s practice paid £36 a seat a month for off-the-shelf PSA, then re-keyed half of it into a spreadsheet because the WIP report didn’t match what partners knew in their heads. Eighty fee-earners, and nobody could answer the under-recovery question on a Friday afternoon without a day of digging.

The firm this page is for£36/seat × 80 · recovery rate guessed · owned
Nadia ran 80 fee-earners. The work was billed. The recovery rate was a guess.
The software wasn’t the problem on its own. The shape was. Time tracking lived in one tool, invoicing in another, the conflicts check in a third, and the SRA audit log nowhere a regulator could read it. Every handover between matters lost a few billable hours nobody chased.
We built the professional services software her firm owns: one matter intake, time against billables, WIP and utilisation per partner, invoicing through Stripe and GoCardless, with the SRA-aware audit log wired in. This page is for the firm where billable hours and matter handover both decide cash flow.
Process
Audit your matter flow, then a fixed quote
Professional services software the way a managing partner wishes the last vendor had run it. Five steps, the same seniors all the way, regulator-aware from day one and yours forever at handover.
Step-01
5-day PSA audit
We map your matter flow, pick the stack, and write the architecture. Fixed at £8K, no commitment to build.
Step-02
Signed scope, fixed quote
A line-item scope in GBP and one number for the twelve-week build. No per-seat rent, no surprise invoice.
Step-03
Regulator-aware build
Matter intake to paid invoice, with SRA, ICAEW, ARB, or RICS rules and the audit log wired in from day one.
Step-04
Senior-only sprint
Two seniors paired daily, no juniors on production code. The engineers who signed your scope write every commit.
Step-05
Yours forever
IP assigns on commit, the repo is yours, the handover pack briefs your next hire. Walk away in 30 days.
Six pieces.
Every one in your repo, regulator-aware.
The shape is the same across every vertical. You get the workflow your partners run, not a rented approximation of it. Open any row.
Conflicts engine (SRA for law), AML and KYC through Sumsub or Onfido, engagement-letter generation in one flow.
Timer, manual, and email-based capture. Auto-categorisation by client. Recovery-rate reporting per partner.
Partner-level, team-level, and matter-level. Slack alerts the moment a matter slips into under-recovery.
Send invoices, take payment, chase Net 30. Xero and QuickBooks sync. Trust accounting where the rules need it.
iManage, NetDocuments, and SharePoint connectors. eIDAS-grade signatures via DocuSign or HelloSign with an audit log.
SRA, ICAEW, ARB, and RICS rules wired in. Audit log per matter touch. Regulator-defendable on the day they ask.
The pain. The custom-build answer.
Every managing partner who emails us is fighting one of these. Each one is the gap between rented PSA and the professional services software your firm actually owns.
- 01
“Every new fee-earner adds another £36-54 a month to a tool we’ve outgrown.”
You own the software, not a per-seat lease. At 80 fee-earners the build pays back in a median of 14 months against Clio, Salesforce Service Cloud, or Practice Ignition. New hires cost you nothing extra in licences.
- 02
“Nobody can tell me our recovery rate on a Friday without a day of digging.”
WIP and utilisation per partner, live. Recovery-rate reporting at partner, team, and matter level. Slack alerts the moment a matter slips into under-recovery, not at month-end when it’s too late.
- 03
“Every matter handover loses a few billable hours nobody ever chases.”
Time capture in three ways, one ledger. Timer, manual, and email-based capture all land on the same matter, auto-categorised by client. The hours stop falling between the people who worked them.
- 04
“Time lives in one tool, invoicing in another, conflicts in a third. We re-key everything.”
One spine, intake to paid invoice. Matter intake, time, WIP, invoicing, and documents in one app. Stripe and GoCardless for payment, Xero or QuickBooks sync for the books. No more spreadsheet in the middle.
- 05
“Our conflicts check is a partner’s memory and a shared inbox.”
Conflicts engine at intake, AML wired in. SRA-aware conflicts run at matter open. AML and KYC through Sumsub or Onfido. The engagement letter generates from the same record, so nothing opens without the checks behind it.
- 06
“Our SRA audit log lives nowhere a regulator can actually read it.”
Audit log per matter touch, regulator-defendable. SRA, ICAEW, ARB, and RICS rules wired in. Every touch on a matter is logged with actor, time, and action, exportable for the day the regulator asks.
- 07
“Engagement letters and client docs bounce around email for days before anyone signs.”
eIDAS-grade signatures with an audit log. DocuSign or HelloSign wired into the matter, with iManage, NetDocuments, or SharePoint connectors. The signed copy and the audit trail land on the record automatically.
- 08
“If we build this with you, are we trading one lock-in for another?”
Your repo from commit one. The code lives in your GitHub org, IP assigns on commit, and you get the architecture brief plus runbook at handover. 30-day walk-away both ways. Hireable forever, on a stack the UK market knows.

What managing partners actually ask before signing
Pain-first, soft-second. The questions every firm asks before it owns its own PSA software.
The honest answer is headcount-dependent. At 80 fee-earners, professional services software you own pays back in a median of 14 months against Clio, Salesforce Service Cloud, or Practice Ignition rent. Below 30 fee-earners, off-the-shelf usually wins and we’ll tell you so in the audit week. Most builds we sign land between £45K and £110K on a twelve-week fixed-price sprint, with the £8K audit decoupled so you can walk after week one with the scope and no further commitment.
The compliance layer is wired into the matter, not bolted on after. The conflicts engine runs at intake against SRA rules, AML and KYC go through Sumsub or Onfido, and the engagement letter generates from the same record so a matter can’t open without the checks behind it. Every touch on a matter is logged with actor, time, and action, exportable for the day the regulator asks. We do the same shape for ICAEW, ARB, and RICS depending on your vertical.
Three things make it hard to fake. The 30-day walk-away clause goes both ways and refunds the unused portion. Payments are milestoned 25/25/25/25, so you never pay more than a quarter ahead of working software. And we’ve been shipping since 2019 with 200+ projects under our name, UK VAT registered and listed on Companies House. You can check us before you sign a thing.
This is the single biggest risk with a small studio, and the reason we pair. Every project has two senior engineers on it, not one. Every decision goes into an ADR the same day, and every commit goes through Mohit’s review. If one engineer leaves, the other has full context the next morning. Two engineers have left mid-project in seven years. Both handovers were inside 48 hours, and neither client noticed in their sprint.
Yes, two-way. Invoicing runs through Stripe and GoCardless inside the app, and the books sync to Xero or QuickBooks so your finance team isn’t re-keying anything. Where the rules require it, we wire trust accounting in too. The point of building professional services software you own is that the matter, the invoice, and the ledger all reference the same record instead of a spreadsheet in the middle.
We ship on the MERN stack, MongoDB, Express, React with Next.js, and Node.js, with AWS for infra. As of 2026 that’s the largest hiring pool in the UK and globally. London alone has 14,000+ Node engineers on LinkedIn. Any senior full-stack developer your future CTO interviews is fluent in your stack on day one. Boring on purpose, hireable on purpose.
That’s the part we design for. You get an architecture brief, ADRs, a runbook, a signed DPA, and a security questionnaire pre-filled with SIG-Lite and CAIQ answers at handover. Zero customer-data breaches in seven years, SOC 2 Type II achieved at Empyreal in December 2025, and the Vanta evidence pipeline can be wired Day 1 on your build. The documents the diligence team asks for are the ones we ship as standard.
You walk away cleanly. The handover pack includes the architecture brief, ADRs, runbook, DPA, and a video tour of the codebase for your next engineer. There’s an optional £5K-a-month advisory retainer if you want a senior voice on your engineering calls, cancellable with 30 days’ notice, any month. Median client tenure on retainer is 28 months, but it’s a choice, not a lock-in. No surprise renewals.
