Most founders treat accounting software as a chore-completion device: somewhere the receipts go to die until the accountant asks for them in month fourteen. Used properly, FreeAgent is the opposite — a live read on the four or five numbers that decide whether the company survives the next two quarters. The difference is almost entirely in the setup and a twenty-minute weekly habit, not in the software.

Here is how to get that value out of it, with the arithmetic worked through so you can see what the numbers on screen are actually telling you.

Set it up so the data arrives on its own

A dashboard is only as good as the feed behind it. Three things have to be true before anything else is worth doing.

  • The company banks separately from the founders. Not a preference — a limited company is a separate legal person and its money is not yours. A dedicated business account also makes the feed clean, which is what makes the dashboard trustworthy. Our page on business banking for startups covers the options.
  • The bank feed is connected, not imported. Open banking feeds pull transactions automatically. Manual CSV imports drift, get duplicated, and quietly stop happening in the week you most need the numbers.
  • Recurring transactions are given rules. Your cloud hosting, software subscriptions and rent are the same every month. Set the explanation once and they classify themselves from then on, which is what reduces the weekly job from an hour to twenty minutes.

Add receipt capture from the mobile app as expenses happen, and the shoebox problem disappears entirely.

The five numbers worth reading every week

Not the profit and loss account. For an early-stage company these five do the work:

  1. Cash in the bank — the only number that is a fact rather than an opinion.
  2. Money owed to you — invoices raised and unpaid, and how old they are.
  3. Money you owe — bills entered but not yet paid.
  4. Tax accrued but not yet due — corporation tax, VAT and PAYE building up in the background.
  5. Net monthly burn — money out minus money in, which is the only input to your runway.

The last two are where founders get hurt. Cash in the bank looks healthy right up to the quarter when a VAT return, a payroll run and a corporation tax bill land in the same six weeks.

Worked example: turning the balance into a zero-cash date

Illustrative figures. A seed-stage company on 1 September 2026.
  • Cash in the bank: £180,000
  • Monthly costs (salaries, employer NIC, hosting, rent, software): £42,000
  • Monthly receipts from customers: £16,000
  • Net burn: £42,000 − £16,000 = £26,000 a month
  • Runway: £180,000 ÷ £26,000 = 6.9 months — cash out around early April 2027
Now subtract the £14,000 of VAT sitting in the bank balance but owed at the end of the quarter, and the true figure is £166,000 ÷ £26,000 = 6.4 months, or mid-March. Two weeks of runway that existed only because nobody separated the tax.

That is the whole argument for reading the numbers weekly rather than quarterly. Raising takes three to six months, so a founder who learns in February that the money runs out in March has no options left. One who has watched the zero-cash date move all autumn starts the conversation in November from a position of strength. Our guide to runway and forecasting takes that further, including how to model the hire you are considering before you make it.

A corporation tax bill that never ambushes you

FreeAgent keeps a running corporation tax estimate as the year unfolds and shows upcoming deadlines on its tax timeline, so the first CT bill is a number you have watched build rather than a January surprise that eats the runway earmarked for a hire.

The arithmetic is worth understanding, because the effective rate is rarely the headline one. Corporation tax is 19% on profits up to £50,000 and 25% on profits over £250,000, with marginal relief smoothing the gap between. Marginal relief is calculated as 3/200 of the difference between the £250,000 upper limit and your profits.

Worked example — illustrative. A company with taxable profits of £60,000 and no associated companies.
  • Tax at the main rate: £60,000 × 25% = £15,000
  • Marginal relief: (£250,000 − £60,000) × 3/200 = £2,850
  • Corporation tax due: £15,000 − £2,850 = £12,150
  • Effective rate: 20.25%
Both thresholds are reduced proportionately for short accounting periods and divided between associated companies, which is why a founder with two companies can pay more tax on the same profit than a founder with one.

The payment date catches people out more often than the rate does. For a company of this size, corporation tax is due nine months and one day after the end of the accounting period, while the CT600 return is not due for a full twelve months. The money leaves three months before the paperwork is required. Set the cash aside monthly against the running estimate and that stops mattering. Our guide to corporation tax for startups goes through the reliefs that reduce the number in the first place.

Invoicing that actually gets you paid

Every day an invoice sits unpaid is a day of runway you have lent to a customer, interest-free. FreeAgent will send automatic payment reminders on a schedule you set, attach card and open-banking payment links so paying takes one tap, and show you an aged debtor view of who owes what and for how long.

The practical win is emotional rather than technical: chasing feels awkward, so founders defer it, and a software-sent reminder on day 31 carries none of that weight. Set the reminder schedule once — a nudge at seven days before due, on the due date, and at seven, fourteen and thirty days after — and the awkward conversation happens only for genuine problem payers.

VAT and payroll, before they become emergencies

You must register for VAT once taxable turnover exceeds £90,000 in any rolling 12-month period — any twelve consecutive months, not your financial year — and you have 30 days from the end of the month you crossed it to register. A growing startup can pass that line without noticing. Keeping the books current means the rolling total is visible rather than discovered.

Once registered, FreeAgent prepares and files VAT returns under Making Tax Digital directly to HMRC. It also runs payroll with real-time information submissions, which matters the moment you make a first hire and become responsible for someone else's tax as well as your own.

The numbers investors ask for

When you raise, even a small angel round, investors want current accounts and a defensible picture of burn, revenue and runway. A company that has kept its books tidy from day one produces that in an afternoon. One that has not spends a fortnight reconstructing eighteen months of bank statements and looks amateur doing it, during precisely the weeks when it should look sharp. Investor-readiness is mostly bookkeeping you did not defer — and it is the raw material for the monthly investor update that keeps a round warm between conversations.

Your twenty-minute weekly routine

  1. Explain the week's bank transactions — with rules in place, most are already done.
  2. Photograph any receipts still in your wallet and clear them.
  3. Read the aged debtor list and chase anything past 30 days.
  4. Write down cash, net burn and your zero-cash date. Keep the running list; the trend tells you more than the level.
  5. Once a month, move the accrued corporation tax and VAT into a separate savings account so the balance you see is money you can actually spend.

What it costs, and why we include it

FreeAgent's limited company plan lists at £33 a month or £330 a year excluding VAT, with an introductory 50% discount for the first six months or first year. It is free for as long as you hold a NatWest, Royal Bank of Scotland, Ulster Bank or Mettle business account. It is also included in every one of our startup packages — set up for you, connected to the bank, with rules configured and a named accountant checking the numbers and answering questions on WhatsApp. More detail on how we use it is on our FreeAgent page.

The software is half the value. The half that spots the mistake, tells you the tax number three months early and files on time is the accountant. Get started and we will have it running properly this week.
