Most UK startups spend anywhere from a low amount to a few thousand pounds a month on accounting, with basic bookkeeping at the low end and full outsourced finance support at the top. Where you land depends on your complexity, particularly payroll, VAT and specialist claims such as R&D or SEIS/EIS. Firms like Price & Accountants structure packages around these factors rather than charging a flat rate for every business.
TL;DR:
- Price & Accountants charges £249 monthly for Core Services, £549 for Blue, and from £1,999 for Black Plan finance director support.
- Transaction volume, clean records, VAT filing frequency, payroll headcount, and specialist R&D or SEIS/EIS work shape fees; historic bookkeeping cleanup often costs extra.
- Request a fixed annual quote that states transaction and payroll assumptions, then confirm whether VAT, payroll, year end filings, and advisory work are included.
- Budget statutory fees separately: from February 1, 2026, digital incorporation costs £100, annual confirmation statements cost £50, and voluntary strike off costs £13.
- Early stage startups usually spend less outsourcing than hiring full time; a dedicated finance employee generally makes sense well beyond seed stage.

Typical fee bands and what each band includes
Accounting costs tend to cluster into three bands, and matching your stage to the right one stops you overpaying or under-buying support.
A solo founder with a handful of transactions a month typically sits in the entry band: basic bookkeeping, a simple set of monthly reports and not much else. A five-person pre-seed team usually needs the middle band, where VAT and payroll enter the picture alongside more frequent reporting. A VC-backed company scaling headcount and spend usually needs the top band, where reporting becomes strategic rather than purely compliance-driven.
- Entry/basic bookkeeping: monthly transaction recording, bank reconciliation and light-touch reporting, suited to a founder with minimal activity and no payroll.
- Growth/scale band: adds VAT returns, payroll for a small team and quarterly management accounts, suited to businesses hiring their first employees.
- Full outsourced/FD band: monthly management reporting, cashflow forecasting and strategic advisory, suited to funded businesses that need board-ready numbers.
Published market guides commonly cite basic bookkeeping starting around £150 to £500 a month, rising toward £1,500 a month for comprehensive outsourced accounting with advisory support layered in. Price & Accountants structures its own packages along similar lines: Core Services at £249 per month covers the fundamentals, the Blue Plan at £549 per month adds scope for growing teams, and the Black Plan from £1,999 per month brings in finance director level support. The jump between bands is rarely about the bookkeeping itself. It is about how much judgement, compliance work and reporting frequency sits on top of it.
What drives your accounting bill
Four factors move your quote more than anything else, and most of them are within your control before you even approach a firm.
Transaction volume is the obvious one: more invoices, receipts and bank lines mean more time on reconciliation. Bookkeeping quality matters just as much. Messy or unreconciled records often trigger a separate catch-up fee on top of the quoted monthly price, since most firms quote for a clean, up-to-date ledger rather than for sorting out a backlog. VAT registration and return frequency add recurring work, particularly once you are filing quarterly rather than annually. Payroll and pension duties scale with headcount: auto-enrolment setup, monthly or weekly pay runs and pension contributions all add administrative time.
Specialist work adds a further layer. R&D tax credit claims require detailed documentation of qualifying expenditure, and Gov sets out the technical steps involved in working these out. SEIS and EIS compliance and cross-border setup work follow the same pattern: more expertise, more time, a higher fee.
- Clean bookkeeping avoids catch-up charges that can land as a surprise on your first invoice.
- VAT frequency (quarterly versus annual) changes the recurring workload your accountant carries.
- Payroll headcount and auto-enrolment add fixed administrative time each pay cycle.
- Specialist claims such as R&D or SEIS/EIS justify a scoped fee rather than a flat monthly rate.
Pro Tip: Reconcile your bank feed in Xero or QuickBooks before requesting quotes. It gives suppliers an accurate picture of your real transaction volume.
In-house hiring versus outsourcing: which makes sense
The headline cost comparison usually favours outsourcing for early-stage startups, since a full-time finance hire carries salary, employer National Insurance, pension contributions and overheads that typically exceed an outsourced retainer at the same stage. Outsourcing also gives you access to senior expertise, such as R&D or SEIS specialism, without carrying that cost on your own payroll.
- Choose in-house once transaction volume and reporting needs justify a dedicated person, usually well beyond seed stage.
- Choose outsourced bookkeeping or a package plan when you need predictable monthly costs and standard compliance work handled reliably.
- Choose a part-time outsourced FD when you need investor-ready reporting, cashflow forecasting or funding support without a full-time salary commitment.
- Blend the two once you have an in-house bookkeeper and retain outsourced advisory for tax planning and strategic decisions.
Predictability is the main advantage outsourcing offers a young startup: a fixed monthly fee replaces variable employment costs and the recruitment risk of hiring your first finance person too early.
Package checklist: what to include in a quote
Before accepting any quote, get suppliers to confirm exactly what is bundled and what is billed separately. This is the single easiest way to avoid a bill that creeps up every few months.
- Core inclusions to expect: bookkeeping frequency, VAT returns, payroll runs, year-end accounts, corporation tax filing and confirmation statement preparation.
- Common add-ons: catch-up bookkeeping for historic records, R&D claim preparation, payroll auto-enrolment setup and bespoke advisory time beyond standard check-ins.
- Questions worth asking directly: request a fixed annual price alongside the assumed transaction volume and payroll headcount it is based on, so you know what triggers an increase.
Ask suppliers in writing for “a list of included transactions and services, plus a fixed annual price based on stated assumptions.” That single request surfaces most hidden costs before you sign anything.
Pro Tip: Get the quote’s assumptions in writing, not just the headline price. A £249 monthly fee means little without knowing how many transactions or payslips it covers.
Companies House and other statutory costs to budget for separately
Statutory filing fees are paid directly to the registrar and are not usually included in an accountant’s monthly fee unless a supplier says so explicitly. From 1 February 2026, Companies House digital incorporation costs £100 and the digital confirmation statement costs £50, figures also confirmed in the published fee change table, which lists a £13 digital voluntary strike-off fee as well.
| Statutory filing | Fee (digital, from 1 February 2026) |
|---|---|
| Company incorporation | £100 |
| Confirmation statement | £50 |
| Voluntary strike-off | £13 |
Build these into your first-year cash plan separately from any accounting retainer, since they recur annually in the case of the confirmation statement.
Why Price & Accountants understands startup budgeting
Rahamut writes on behalf of Price & Accountants, a London-based firm with over 40 years of experience supporting UK tech and fintech startups. Core services include SEIS/EIS compliance, R&D tax credits, cloud accounting on Xero and outsourced finance director support for funded businesses. The firm has completed start-up processes for more than 20 clients, some now valued well over £50m, and facilitated over £10m in client funding, giving it direct experience of the budgeting decisions founders face at each stage.
What founders consistently get wrong about accounting budgets
Most founders compare accounting fees the way they compare software subscriptions: lowest headline price wins. That approach backfires because the cheapest monthly quote rarely states its assumptions, and the catch-up fee or add-on charge that follows often costs more than the gap between that quote and a properly scoped one.
The conventional advice, “shop around for the cheapest package”, misses the real lever: scope clarity. Two quotes at £249 and £400 a month can cover wildly different transaction volumes, and the cheaper one may exclude payroll entirely. Founders who ask for assumptions in writing before comparing prices consistently end up with a more accurate budget than those who compare headline numbers alone.
If you prioritise one thing, prioritise this: get a fixed annual price tied to stated transaction and payroll assumptions, not a monthly figure in isolation. It is the difference between a budget you can trust and one that surprises you every quarter.

FAQ
How much should a UK startup budget for accounting monthly?
Most startups budget between roughly £150 and £1,500 a month depending on complexity, with basic bookkeeping at the lower end and full outsourced finance support at the top. Price & Accountants’ own packages range from £249 a month for Core Services to a Black Plan from £1,999 a month for FD-level support.
What is usually excluded from a standard accounting package?
Catch-up bookkeeping for historic or unreconciled records, R&D claim preparation, payroll auto-enrolment setup and bespoke advisory time are commonly billed as add-ons rather than bundled into the headline monthly fee. Always ask suppliers for a written list of inclusions before comparing quotes.
Do accounting fees cover Companies House filing costs?
No, statutory filing fees are paid directly to Companies House and are separate from your accountant’s fee. From 1 February 2026, digital incorporation costs £100 and a confirmation statement costs £50.
Why do R&D and SEIS/EIS claims cost more to handle?
R&D and SEIS/EIS work involves detailed technical documentation and qualifying expenditure calculations, as set out in GOV.UK’s R&D guidance, which takes more time than routine bookkeeping. Firms typically scope this as a separate project fee rather than folding it into a basic monthly package.
Is outsourcing cheaper than hiring an in-house accountant for a startup?
For most early-stage startups, outsourcing tends to cost less than a full-time hire once salary, employer National Insurance and pension contributions are factored in. Outsourcing also gives access to specialist expertise, such as R&D or FD-level support, without carrying that cost on your own payroll.
