Think of it as recording, running, and interpreting. Each layer depends on the one below it.

Recording. Bank transactions coded, supplier bills entered, sales invoices raised, banks reconciled, VAT prepared from reconciled books rather than a spreadsheet estimate. This is bookkeeping, and it’s the product. Everything above it inherits its errors.

Running. Payroll and auto-enrolment on schedule, supplier payment runs, credit control chasing on a routine rather than when cash gets tight, and somebody watching the debtor list weekly. This layer is where money physically moves, so it’s also where money physically goes missing.

Interpreting. Monthly management information: cash position, debtors, creditors, gross margin by whatever unit matters in your business, and a view of what’s coming. Then the conversations that follow from it, about hiring, pricing and funding.

The profession pays close attention to the statutory accounts that sit at the very top and treats the recording layer as admin to be got through. That’s backwards. A forecast built on records that are six weeks behind is a guess in a nicer font.

A typical accountancy engagement covers year-end accounts, the corporation tax computation, the company tax return, directors’ self assessment, and often quarterly VAT. That work is real and it has to happen. From 1 April 2026, companies must file annual accounts and Company Tax Returns with HMRC using commercial software, because the old HMRC online service closed on 31 March 2026. Late Corporation Tax return penalties doubled from the same date.

What that engagement usually does not cover is the running layer or the interpreting layer.

Nobody is chasing your debtors. Nobody is checking that every delivery got invoiced. Nobody is telling you in week two of October what September looked like. The accounts arrive months after year end, tidy and accurate, describing a business you have already changed twice since.

I’m not criticising the profession for this. It’s what the engagement was scoped to do. The problem is that owners assume the scope is wider than it is, and only find out when they need a number in a hurry and there isn’t one.

Here’s how the work divides in a business turning over roughly half a million with five or more staff.

The point of writing it down is that unassigned work doesn’t get done. It gets half done by the owner on a Sunday, which is the most expensive labour in the business.

Ask yourself one question. What is the most recent month for which you know your cash position, your debtor balance and your margin, and how many days ago did that month end?

If the answer is under twenty-one days, your finance function is working. If it’s two months or more, you are making decisions on memory and bank balance, which are both unreliable narrators. A healthy bank balance can simply mean you haven’t paid your suppliers or your VAT yet.

The consequences of the gap aren’t dramatic, which is why it persists. You hire one month later than you could have. You keep a supplier whose prices crept up. You quote the same rate you quoted two years ago on work that now costs more to deliver. None of these show up as a crisis. They show up as a year that felt busy and ended thinner than expected.

Questioning is how things surface. Reconciling a sales ledger against delivery records for one owner-managed trading business turned up £20,000 of goods supplied and never invoiced. That was found in the recording layer, not in the accounts.

Ninety days, done in order, is the honest timetable. You can’t skip to reporting.

Month one is foundations. Bookkeeping brought complete and accurate, banks reconciled, supplier and customer balances made to make sense, historic gaps identified. Alongside that, the responsibility map: who does each part of the finance process and how information moves between you and us.

Month two is process. Regular routines for bookkeeping, supplier bills, credit control, payroll and reporting. Checks and controls put in. Duplicated and manual work removed where that’s practical.

Month three is the finance function running to an agreed timetable. Accurate records, visibility over cash, debtors, creditors and performance, and management information arriving on a date you can plan around.

After that it’s routine rather than rescue. Queries answered quickly, reports on the agreed dates provided the information is with us, and the reporting developed as the business grows. If you want the detail, how the first 90 days work sets out each stage.
