The Week-One Cash Reality Check: Can the Business You Just Bought Pay Its Own Way?

Last Updated: 2026-09-10

In week one, measure three things about cash before you improve anything else: how much customers owe the business and how old those debts are, how late customers actually pay against the terms on their invoices, and how many weeks the business could cover its own outgoings from the money it holds. Those three numbers answer a question no forecast answers: whether the business you just bought can pay its own way while you fix it.

The Money You Are Owed Is Invisible at Close

The receivables position of an acquired business is the single largest number nobody hands over. Completion accounts cover the balance sheet in aggregate, but they do not tell you which customers pay in thirty days, which pay in ninety, and which have quietly stopped paying at all. Until someone works through the ledger customer by customer, the headline sales figures conceal the truth about when money actually arrives. That gap is not exotic. Government research on late payments estimates that UK businesses are owed around £26 billion in late payments at any given time, an average of £17,000 for each affected business, and that 28% of businesses are affected every year. The Department for Business and Trade, which published the research in July 2025, found the problem touches more than 1.5 million businesses annually. A newly acquired business does not escape that distribution by changing hands.

Building the Aged Debtor Report

The practical first step is an aged debtor report, and it is worth spelling out what that actually involves. Take the sales ledger as it stood on the day you took ownership. For every open invoice, record three things: the customer, the amount, and the number of days since it was issued. Then sort the whole list by age, not by customer. The result is usually uncomfortable and always informative: a cluster of current invoices, a band of debts past thirty days, and a tail of old balances the previous owner had stopped chasing. As an illustrative example with invented figures: a trade-services business shows £340,000 of receivables, of which £60,000 sits past ninety days attached to three customers. That £60,000 is not working capital. It is a question about the business you now own: were those customers lost, disputing, or never going to pay? The report does not answer the question, but it makes the question findable, which is more than the balance sheet does.

Stated Terms Are Not When Money Arrives

The payment terms printed on an inherited invoice tell you what was agreed, not what happens, and the difference between the two is the real cash cycle. Official survey evidence puts numbers on that gap: according to the Department for Business and Trade's payment-practices research with IFF Research, 49% of small businesses said their customers took longer to pay than the agreed terms, against 36% of businesses overall. On average across the surveyed businesses, 17% of payments arrived late. If you assume the contract terms describe reality, you will forecast money arriving roughly one payment in six late at best, and at small-business scale roughly half the time. Neither is a basis for running payroll.

Why the Money Is Late, and What That Tells You

The reasons customers pay late matter, because they split into things you can fix and things you cannot. The same research asked businesses why payments to them arrived late: 24% of surveyed businesses attributed late payments to administrative errors, such as invoices that were never logged or contained mistakes, and the study of payment practices more broadly found 36% of businesses attributed their own late supplier payments to administrative errors, 31% to disputed invoices, and 23% to technical issues, including invoices that got lost or never arrived. That finding is quietly good news for a new owner. A meaningful share of late payment is process failure, not refusal: the invoice went to the wrong person, the purchase order never matched, the payment run was missed. You did not cause those failures, but you now own the process, which means you can fix them. The way to find out which explanation dominates in your business is a days-to-payment log: for a rolling window of invoices, record when each was issued, when it was actually paid, and the gap in days. Within a month the log separates the customers who pay late because your invoice process is broken from the customers who pay late because they always will.

The contrast between what the two records show is the point of keeping both:

Chasing Payment Is a Real Operating Cost Nobody Budgets

Late payment is usually discussed as a finance problem, but it consumes operating time, and that time is real cost. According to the government's late-payments research, business owners affected by late payment spend an average of 86 hours a year chasing invoices, and 22% of surveyed businesses said chasing late payments took staff time, adding up to an estimated 133 million hours across UK businesses each year. Read those numbers the way a new owner should read them: in roughly one business in five, somebody spends real working hours persuading customers to pay for work already done. Inherited businesses usually arrange this work informally, and the arrangement lives in one person's habits. Sometimes it is the previous owner themselves, which means the chasing has quietly stopped and nobody has noticed yet. Either way, the effort is invisible in the accounts, unbudgeted, and unowned in any formal sense.

Make the Chasing Countable

The fix is not more chasing; it is making the chasing visible. Once the days-to-payment log exists, the chasing that remains attaches to named accounts with a history rather than to a general sense that money is slow. And the hours it consumes become countable: time spent on collections in a month, per person, against the value recovered. If that arithmetic is unfavourable, the answer changes from "chase harder" to "change the process", which is a decision you can only make once the hours are on a page.

Cash-Cycle Blindness Is a Survival Risk, Not a Hygiene Issue

It is tempting to file all of this under housekeeping, to be done when the exciting work of improvement is underway. The failure statistics say otherwise. The Insolvency Service's most recent monthly statistics put the rolling company insolvency rate at one in 199 companies in England and Wales in the twelve months to July 2026, and creditors' voluntary liquidations, the procedure directors start themselves when the business cannot pay its debts, accounted for 78% of all company insolvencies in July 2026. Its late-payments research estimates 14,000 businesses a year close because of late payments, 38 every day, at a cost of nearly £11 billion a year to the UK economy. A business running on assumed terms and an uninspected ledger is exposed to exactly this mechanism: the sales are real, the invoices exist, and the money does not arrive in time to pay for the next month.

Why the Risk Peaks for a New Owner

The first 100 days are when this risk peaks for a new owner, for an unflattering reason: the previous owner's relationships and informal credit control lapsed the day they left, and yours have not yet formed. Customers who paid on time for the old owner out of loyalty wait longer for a stranger. Staff who knew which customer could be safely chased and which needed kid gloves may not know they were supposed to tell anyone. None of this appears in a management account until a quarter has closed. It appears in a weeks-of-cover calculation in week one.

The Week-One Cash Baseline: Three Documents and a Named Owner

The whole exercise produces one dated document with three parts, and it belongs in week one, not month three. First, the aged debtor report: every open invoice with its customer, amount and age, sorted by age, with the oldest tail flagged for individual decisions, chase, query or write off. Second, the days-to-payment log: issued date, paid date and gap for a rolling window of invoices, which establishes what the business actually collects against what it invoices. Third, the weeks-of-cover calculation: money held plus money confidently collectable in the near window, divided by typical weekly outgoings. As an illustrative calculation with invented figures: £85,000 held, £70,000 of receivables under sixty days old judged genuinely collectable, and £30,000 of weekly outgoings gives five weeks and change of cover. That single number tells you whether you have months to improve the business or days to stabilise it.

The Governance Habit That Keeps It Alive

This is also where the governance habit matters as much as the arithmetic. When Synergised builds its own automated workflows, no process runs until it has a named owner, a written baseline and a defined exception path, because those are the things that make a number checkable instead of asserted. A cash baseline responds to exactly the same discipline: the debtor report has a named owner, the bookkeeper or finance lead who maintains it; the log has a cadence, updated weekly and reviewed monthly; and the exceptions, the invoice nobody can chase because the contact left, the dispute nobody has priced, have a route to the owner's desk rather than a drawer. Set up this way, the baseline is a working instrument rather than a one-off audit: re-run it monthly and it shows whether the process fixes are working, whether the ninety-day tail is shrinking, and whether the collection gap between stated terms and actual payment is closing.
