You know your bank balance. You don't know your year.

None of this is clever. A budget, a forecast, management accounts and a meeting: a competent finance director has done that for decades. What an owner-managed business lacks is not the idea but the discipline — somebody whose job it is to build the plan and work out why the result came in different.

That last part is the product. A pack of reports emailed over on the 14th changes nothing by itself. The value is the hour where somebody who has read your numbers says which variances matter.

You cannot report against a plan that does not exist, and writing it down is where most of the thinking happens. So we take what you know about the year ahead — the contracts you expect to keep, the work you expect to win, the people you plan to hire — and turn it into month-by-month numbers, with the assumptions written beside them. When a result comes in different, the assumption is usually what was wrong.

If trading is steady and customers pay much the same way every month, quarterly is enough: three months is long enough for a trend to be a trend rather than a wobble. Review monthly if a single month can knock the year off course — staff whose cost is fixed but whose work is not, margins that move with materials rates, borrowing to service. Catching a margin problem in week four leaves eight weeks to fix it. In week fourteen you have paid for it.

A grounds-maintenance company, nine staff, on quarterly Business Pulse. Most revenue is maintenance contracts billed monthly; the rest is project work quoted job by job. This is its first quarter.

Revenue came in £30,000 ahead of plan, ten per cent up, and the owner knew he had been busy. Operating profit came in £6,100 below plan. Without a budget, that second fact does not exist at all.

The extra £30,000 was worth £12,900 of gross profit at the budgeted 43 per cent. Margin swamped it: 38 per cent against a planned 43, and five points off £330,000 is £16,500.

Splitting revenue by type showed where those five points went. £247,500 of contract work ran at 44 per cent; the remaining £82,500 of project work ran at 20. Blended, that is exactly the 38 per cent in the accounts — and neither figure is visible while both are reported together, which is how they always had been. The project rate had not been reviewed since materials prices moved, and with crews tied up on projects, contract rounds went to subcontractors costing more per hour than the company's own staff.

Cash said the same from the other end: £41,000 at the quarter end against £62,000 forecast. £6,100 of the £21,000 gap was the profit that never arrived; the other £14,900 sat in project invoices to customers past their terms.

Four decisions came out of the ninety minutes.

• Project work is quoted off a rebuilt rate with a 35 per cent margin floor
• Project margin is reported on its own line, never blended into contract margin again
• Two of next quarter's four project jobs move back, so contract rounds go to employed crews
• Project jobs are invoiced with a deposit and a stage payment; the late payers go on stop

Each has an owner and a date, and each is the first item next quarter. The pricing decision alone is worth £12,375 a quarter if that same £82,500 of work is done at 35 per cent rather than 20 — roughly twice what this quarter lost. Your business will look nothing like this one; the mechanism transfers.

Business Pulse suits an owner who has outgrown annual accounts. The decisions have got bigger — a fifth employee, a lease, equipment, a price rise, a bank facility — and accounts filed long after the year end help with none of them.

It suits a business that is changing, because growth is where financial control breaks: margins move as the mix of work changes, payroll gets committed before the revenue turns up, and cash leaves faster than it arrives even as profit rises. And it suits anyone about to spend money who wants the consequences first.

And it suits owners who want to be challenged. Most owner-managers have nobody who asks them what happened: staff will not, family should not have to, and the accounts meeting comes far too late.
