Simple enough to explain in four steps.

No onboarding calls. No software to install. Just send us the work.

Everything goes back out under your firm's name

We are your invisible back office. Every return, every set of accounts is returned formatted and ready for you to send directly to your client. No FirmBooks branding anywhere — your client relationship stays 100% yours.

01

Send us the records

Upload the client's bank statements and invoices to our secure encrypted portal. Tell us the job type and any deadline.

→ Confirmation within 2 hours
02

We complete the work

A vetted, UK-trained accountant handles the job to UK accounting practice standards — here in the UK, not offshore. VAT returns in 48 hours. All other jobs quoted in writing before we start — you approve first.

→ No surprises on scope or price
03

You review and deliver

We return clean, senior-reviewed work with supporting workings. You check it, add your letterhead, send to your client. Done.

→ Free redo if anything isn't right
04

Pay only after delivery

No upfront cost. No contract. Invoiced monthly after the work has been delivered. You approve nothing until you see the quality.

→ Cancel with 30 days' notice

What FirmBooks gives
back to you.

Built around the four problems we hear from UK practice owners every week.

01

No more staff churn or recruitment headaches

Junior bookkeepers leave, training takes months, and recruitment fees bite every time. FirmBooks is on-tap UK-trained capacity you turn on and off per job — no hire, no leaver, no gap to plug.

02

Get your time back — stop managing staff

No more chasing juniors, reviewing timesheets, running 1:1s or covering holiday and sickness. We manage the people; you just send the work and review the deliverable.

03

Skip the admin grind, do the work that actually pays

Hand over the data entry, reconciliations and routine VAT prep. Use the freed-up hours for advisory, tax planning and higher-value client work — the things that actually grow your fees.

04

A softer route into part-retirement

Not ready to fully retire? Let FirmBooks run the back office while you stay client-facing — meetings, advisory, relationships — on the days you choose. Wind down without walking away from the practice you built.

Fixed monthly tiers.

No contract. Pay monthly after the work is delivered — never upfront. Every tier includes a dedicated UK account manager, 8am to 10pm.

How can a UK-based service price this low?

The saving is not from cheap labour — FirmBooks is 100% UK-based with UK-trained accountants on UK pay. It's from bespoke software we built in-house that removes most of the manual hours from each job. A UK accountant still does the judgement and the senior review on every deliverable — we just need far fewer hours per job than a traditional workflow.

Book meeting

We know what's at stake for your firm.

Your reputation is on every document we touch. Here is exactly how we protect it.

UK-trained, UK-based staff

Every accountant is UK-trained, ACCA-familiar, background checked, and works to UK accounting practice standards. Our operation is in the United Kingdom — not offshore.

Signed data processing agreement

We issue a full GDPR-compliant DPA before any client data is shared. Encrypted transfer, zero third-party sharing, no exceptions.

Free redo guarantee

Not satisfied? We redo it at no charge. Your first two jobs also carry a full money-back guarantee — no questions asked.

Senior review before delivery

Every job is checked by a senior accountant before it leaves us. You are not the quality control — we are.

No lock-in, ever

No contract, no minimum volume, no upfront fees. Invoiced monthly after the work is delivered. Stop whenever you want with 30 days' notice.

Completely white-label

Nothing carries FirmBooks branding. Your client sees your firm's name on everything. We are invisible by design.

100% UK-based. Not offshore.

FirmBooks is the UK-based, onshore alternative to offshore accounting outsourcing. UK-managed, UK-staffed and quality-controlled in the United Kingdom. Our UK-trained accountants work to UK accounting practice standards: UK VAT rules, Companies House requirements and HMRC filing — not generic global bookkeeping repurposed for the market.
