Startup Bookkeeper

Your startup books, properly handled.

Most founders start doing their own bookkeeping to save money, then gradually fall behind until year-end becomes a scramble. The records are there — they just need someone to take them over and keep them current. Fixed monthly fee, ICAEW chartered, same-day replies.

  • Clean, current books on Xero every month — no year-end catch-up
  • Know your corporation tax liability well before it is due
  • VAT threshold monitored — no unexpected registration obligations
  • A named, chartered accountant who answers questions the day you ask them

No long-term contract. If it is not working after three months, you leave with clean books and nothing owed.

Sound familiar?

Still doing your own books to keep costs down?

Most startups begin that way — and it works, for a while. Then the VAT threshold starts to matter, the year-end approaches with records that need serious work, and the tax bill arrives as a number you were not expecting. None of it is unusual, and none of it is catastrophic. It does take longer to sort the more it is left, though.

  • Time spent on bookkeeping that should be going into the business
  • No clear picture of tax liability until the return is actually due
  • Records that have drifted behind and need catching up before they can be useful

What sorted looks like

Bookkeeping handled monthly, so the records are always current. Corporation tax visible throughout the year, not just at the end of it. And someone to call when a question needs answering — without it adding to the invoice.

  • Books reconciled monthly on Xero — no year-end archaeology
  • Tax position visible well before HMRC asks for payment
  • Overdue records caught up and brought current at the start
  • A fixed monthly cost that does not move however many questions you ask

What you get

What your monthly fee covers

Three things that keep your records clean, your tax position visible and your statutory obligations handled — for one fixed monthly cost.

01

Monthly Bookkeeping on Xero

Every transaction categorised, every account reconciled, every month. Your records are current and accurate rather than something to dread at year-end. If something looks unusual, you will hear about it before it becomes a problem.

Included as standard
02

VAT Returns and Registration Advice

Quarterly VAT returns prepared and filed with HMRC, Making Tax Digital compliant as standard. Your VAT threshold is monitored throughout the year — you will not approach registration without knowing it is coming.

Quarterly, fixed fee
03

Year-End Accounts and Corporation Tax

Annual accounts, CT600 and Companies House confirmation statement — all filed on time, no chasing required. Because the books are kept current throughout the year, there are no last-minute surprises when the return is prepared.

No extras, no surprises
What clients say

Startups and small companies across the UK

Sole traders, new limited companies and growing small businesses. Usually arriving with books in some state of disarray. Leaving with considerably less to worry about.

Why Swift

Why startups choose Swift over others

There is no shortage of accountants offering bookkeeping. Here is what is different about working with one who already knows what a new business actually needs.

🧾

No jargon, no assumed knowledge

When you are new to running a limited company, terms like P11D, CT600 and Making Tax Digital are not obvious. You will not be expected to know them before asking. Questions get plain answers, and the process gets explained at each stage. That is how it should work.

💬

Replies the same day

Questions get answered the day you ask them. Not logged, not queued, not passed to a junior — answered. If you want to know whether a cost is deductible or when your VAT return is due, you will know before the end of the day.

🔒

One price, agreed upfront

Your monthly fee is fixed from the start and does not move. No hourly billing, no invoice that arrives larger than expected, no charge for asking a question. Your accounting costs are as predictable as your other fixed overheads — which, for a startup, matters.

Getting started

Up and running in four steps

Four steps from first enquiry to everything being handled. No complicated onboarding, no lengthy forms.

1

Send your enquiry

Fill in the form on this page. Kieran reads every enquiry and responds the same day with a clear next step. No automated holding messages.

2

A short call to understand your setup

Twenty minutes to go through your current situation, what software you are using if any, and what needs sorting. At the end of the call you will know exactly what is included and what it costs — no vague proposals to follow.

3

We handle the setup

Xero is configured, any historical records are brought up to date, and everything is connected. You confirm you want to proceed, and the rest is handled. There is not much you need to do at this stage.

4

Ongoing — nothing falls through

Monthly bookkeeping, quarterly VAT, year-end accounts and corporation tax — handled as a matter of course. Your tax position is visible throughout the year rather than arriving as news. Surprises are largely avoidable when the books are current.

Questions

Questions startups usually ask first

It depends on how much time you are spending on it and how current the records are. For most small limited companies, the cost of monthly bookkeeping is less than the time spent doing it poorly. The other consideration is that clean monthly records make the year-end accounts significantly cheaper and faster to prepare.
Once the books are current, your corporation tax liability becomes visible throughout the year rather than only at the filing deadline. Most clients have a reasonable idea of what they owe three to four months before it is due — enough time to plan rather than react.
It is the most common situation we encounter. Getting up to date takes a little longer at the start and may cost slightly more — we will be clear about that upfront before any work begins. Once current, keeping it current is straightforward.
No. Month-to-month, cancel with a month’s notice. We would rather keep clients because the service is worth it than because leaving is inconvenient.
