The rules that shape this work

Most UK founders reach the same wall between roughly £500k and £5m of revenue: the spreadsheet no longer answers questions, but a financial controller at £65,000 plus employer's National Insurance and pension is more cost than the company can carry. An outsourced finance function fills that gap with a team, bookkeeper, management accountant and finance lead, at a fraction of one salary, and it scales up or down with the month.

Outsourcing does not outsource responsibility. The directors remain legally accountable for accounts, the CT600, VAT returns and RTI submissions, so the arrangement has to include a documented close calendar, approval limits, segregation between who raises and who pays, and audit-ready records. We build those controls in from the start rather than bolting them on before a diligence process.

Thresholds, rates and deadlines quoted here reflect the 2026/27 UK position. Check current GOV.UK guidance, or ask us, before you rely on them for your own company.

How we run it

We start by looking at the last filed accounts, your current records and your filing dates, then confirm a fixed scope and fee in writing.

Once the work is live you get reminders ahead of each deadline, a named person to ask questions, and a plain-English summary when the figures are ready, not a PDF with no explanation.

Frequently asked

Outsourced finance function: questions directors ask

What does an outsourced finance function actually include?

Transaction processing, reconciliations, accounts payable and receivable, payroll, VAT, month-end close, a management pack with commentary, cash forecasting, and a finance lead you can call. Statutory accounts and the company tax return sit alongside it, so nothing falls between two providers.

Is it cheaper than hiring in-house?

Usually, yes, until you need someone full time. A single finance hire costs salary, employer's National Insurance, pension, software, training and cover for holidays and sickness. An outsourced team costs a fixed monthly fee, carries its own cover, and does not need recruiting or managing.

Can you work alongside a bookkeeper we already have?

Yes. A common split is that your bookkeeper keeps the day-to-day ledger and we take month-end close, reporting, compliance and the advisory layer. We agree who owns what in writing so nothing is assumed.

What happens when we do hire a finance person?

We hand over cleanly, documented processes, a working close calendar and reconciled ledgers, and usually stay on for the compliance and advisory work while the new hire runs the day-to-day. That is the outcome we plan for, not one we resist.

What records are needed for outsourced finance function?

Keep bank statements, sales and platform reports, purchase invoices, payroll records, VAT workings, finance agreements and Companies House correspondence. We confirm the exact list at onboarding and identify gaps before a filing deadline becomes urgent.

How much does help with outsourced finance function cost?

The fee depends on transaction volume, record quality, VAT and payroll requirements, historic catch-up and the level of reporting needed. We agree a fixed scope and price before technical work starts, with published packages available on our fees page.

Can you take over outsourced finance function from another accountant?

Yes. We request professional clearance, collect the prior records and authorities, check the next Companies House and HMRC deadlines, and give you one clear handover list. The process is normally completed remotely.

Can outsourced finance function be handled online?

Yes. We work through secure cloud records, scheduled reviews and digital approvals, while keeping a named team available by phone, video call and email. Clients can also visit our Morden office by appointment.

Which accounting software works best for outsourced finance function?

We regularly work with Xero, QuickBooks, FreeAgent, Sage and connected sales or expense apps. The right setup depends on transaction volume, integrations and the reports you need, not simply the software brand.

What tax deadlines matter for outsourced finance function?

The relevant calendar may include annual accounts, Corporation Tax payment and return dates, confirmation statements, VAT returns, payroll submissions and Self Assessment. We map the dates from your company year end and registrations.

What Our Clients Say

Rated 4.9 out of 5From 302 Google reviews
Accotax have been our accountants for many years now. We maintained them because of their professionalism. In the last couple of years I have been working with Imran, who has been very professional and helpful in guiding us through the whole process, explaining and clarifying every aspect of it. Very prompt in responding to questions and patient with us even when we seem to be slow.
Mansur Liman · Long-standing company client
We worked with a few different accountants before finally settling with Accotax, and we're really glad we did. They take the time to understand how our business works and what our needs are. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing, professional, efficient, and follows the processes we have put in place together. Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.
Mael Leboucher · Year end accounts & bookkeeping
I've been working with Accotax since January 2024, and their support has grown alongside my business needs. My personal allocated manager, Umer, provides tailored services for both of my companies, adapting as I expand and ensuring everything runs smoothly. They are responsive, knowledgeable, and always clear in their communication. Their help with accounts, VAT, payrolls, pensions and compliance gives me real confidence and peace of mind.
