Recruitment agencies run one of the toughest working capital shapes in UK business: you pay temporary workers and contractors weekly, but your clients pay your invoices on 30, 45 or 60-day terms. Every time you fill a temp booking, you fund the wage bill first and collect the cash weeks later – so the faster your agency grows, the more cash it swallows.
This is the “pay and bill” gap, and it catches out profitable agencies constantly. On paper the desk is booming. In the bank account, there is never quite enough to make Friday’s payroll. Understanding why – and how to fund it – is the difference between an agency that scales and one that stalls.
Why Recruitment Is a Working Capital Furnace
Most businesses buy stock or materials, add value, then sell. A recruitment agency’s “stock” is people’s time, and the timing of the money is brutally one-sided.
When you place a temporary worker or contractor, you become responsible for paying them – usually weekly, and usually within a few days of them submitting a timesheet. Whether the worker is on your own PAYE payroll, paid through an umbrella company, or invoicing as a limited-company contractor, the money leaves your account fast. Your client, meanwhile, receives an invoice and pays it on their standard terms – which for a large employer can be 45 or 60 days.
So for a single temp on £15 an hour working a 37.5-hour week, you might pay out roughly £560 in wages plus employer on-costs this Friday, and not see the matching £700-odd from the client for two months. Multiply that across fifty temps out on assignment and you are permanently financing a five-figure gap that never closes – it just gets bigger every time you place someone new.
That is why a fast-growing temp desk behaves like a business that is overtrading: growth consumes cash faster than the profit arrives to replace it.
The pattern gets sharper if your billing is concentrated in a few big clients. Land one large account that wants forty temps and your funding need can jump overnight – and if that client also happens to be a slow payer on 60-day terms, the gap you are financing balloons at exactly the moment you can least afford it. Client concentration and slow terms are a dangerous pair in staffing, because both push in the same direction: more cash out, later cash in.
The Recruitment Working Capital Benchmarks
Here is roughly what the numbers look like for a UK staffing agency with a meaningful temp or contract book:
| Metric | Typical benchmark | What it means |
|---|---|---|
| Days Sales Outstanding (DSO) | 45–55 days | Six to eight weeks to collect what clients owe you |
| Days Payable Outstanding (DPO) | 3–7 days | You pay workers almost immediately – there is no float |
| Days Inventory Outstanding (DIO) | 0 days | You hold no stock – but that is no help to your cash |
| Cash Conversion Cycle (CCC) | 40–55 days | Cash is locked up for roughly six to eight weeks per placement |
The killer combination is a high DSO paired with an almost-zero DPO. In most industries you get to hold onto supplier money for a while, which softens the blow of slow-paying customers. An agency gets no such cushion: your biggest “supplier” is the worker, and they must be paid now. Check where your own book sits with the DSO figure and the late payment calculator.
Temp and Contract Desks Versus Permanent Desks
The two halves of the recruitment business have completely different cash profiles, and it is worth being clear about which is straining your account.
Temporary and Contract: The Cash-Hungry Engine
Temp and contract billing is where the pay-and-bill gap lives. Every hour billed has already been paid for. The upside is that turnover is recurring and predictable; the downside is that every pound of growth needs funding. A desk that doubles its temp headcount roughly doubles the cash it ties up – even though margins have not changed at all.
Permanent Placements: Lumpy but Light
A permanent placement is a one-off fee, typically 15 to 25 per cent of the candidate’s first-year salary, invoiced when they start. There is no weekly wage to fund, so perm work is far lighter on working capital. But it comes with two catches: fees are lumpy and unpredictable, and most contracts carry a rebate clause – if the candidate leaves within, say, twelve weeks, you refund part or all of the fee. An agency that has already spent that cash can find itself clawing money back out of a thin account.
Don’t Forget the On-Costs
When you quote a client a charge rate, the gap between that rate and the worker’s pay rate is not your margin – not until you have covered the employment on-costs you carry as the employer of record for PAYE temps.
For 2026 those on-costs are heavier than many agency owners assume. Employer National Insurance runs at 15 per cent on earnings above a £5,000 secondary threshold. Holiday pay accrues at 12.07 per cent of hours worked for irregular-hours workers – and since April 2024 you can pay it as rolled-up holiday pay, shown separately on the payslip, but you still fund it. Pension auto-enrolment adds a minimum 3 per cent employer contribution for eligible workers, and the apprenticeship levy takes another 0.5 per cent once your pay bill passes £3 million. The National Living Wage of £12.71 an hour from April 2026 also lifts the floor under all of it.
Stack those up and a headline £15 pay rate can cost you well over £17 before you have made a penny. If your charge rate does not cover the on-costs and a real margin, you are funding an ever-growing wage bill for a return that barely exists. Model the true figure the same way you would for a direct hire – our guide to the working capital a new hire really requires uses the same logic.

A Worked Example: The Growing Temp Desk
Priya runs an industrial recruitment agency in Leeds, placing warehouse and logistics temps. She has 40 workers out on assignment, each billing around 40 hours a week. Her clients – mostly large distribution firms – pay on 45-day terms.
Every week, Priya pays out roughly £26,000 in wages and employer on-costs. She invoices her clients about £33,000 for the same work. The margin is healthy. The problem is timing: she funds six to seven weeks of payroll – around £170,000 – before the first of those invoices is paid.
Then a client asks her to ramp up to 70 temps for a peak season. The extra 30 workers add roughly £20,000 a week to payroll from day one, but the matching invoices will not be paid for another six weeks. Priya needs to find around £120,000 of additional funding almost overnight – to service a contract that is highly profitable. This is the central paradox of recruitment: winning more work makes the cash problem worse before it makes it better.
A Worked Example: The Perm Desk and the Rebate Trap
Daniel runs a perm-only technology recruitment desk in Bristol. In March he has a bumper month, invoicing £48,000 in placement fees across six hires. He uses the cash to pay a chunky bonus round and a new office deposit.
In May, two of those placements fall through inside the rebate period – one candidate resigns after five weeks, another is let go in probation. Daniel owes £11,000 back to clients under his rebate terms. The money is already spent, and April was a quiet month. He is suddenly negotiating an overdraft extension to refund fees he had counted as profit. The lesson: on a perm desk, treat fees inside the rebate window as provisional, and hold a reserve against clawbacks rather than banking them as certain.
How to Fund the Pay-and-Bill Gap
Recruitment is the classic use case for working capital finance, and the sector has an entire funding niche built around it.
Invoice finance is the workhorse. You raise an invoice, and the lender advances typically 80 to 90 per cent of it within 24 hours, releasing the rest (less a fee) when the client pays. Because the advance scales automatically with your billing, it flexes as you grow – exactly what a temp desk needs. Many providers offer dedicated “pay and bill” recruitment finance that also runs your payroll, timesheets, and credit control in one service, which is why so many agencies use it. Weigh factoring against invoice discounting in our comparison guide, and see why invoice finance usually beats a fixed facility for this pattern in invoice finance versus overdraft.
A bank overdraft, by contrast, is a fixed ceiling that does not grow with your billing – and overdraft applications are frequently declined for younger agencies with few assets. That mismatch is why so many recruiters outgrow an overdraft within a year or two: the facility stays the same size while the pay-and-bill gap keeps expanding. Invoice finance sidesteps the problem because the funding line is secured against the invoices themselves and rises in step with your turnover.
Whichever route you take, tighten the free levers too. Get client payment terms agreed in writing before the first timesheet, invoice weekly rather than monthly so cash comes back sooner, and chase hard – the tactics in how to reduce your DSO apply directly. A week shaved off your collection time on a large temp book is worth thousands in reduced funding.
What to Do Next
Start by separating your temp and perm numbers. Work out how much cash your temp book ties up right now – roughly your weekly pay-and-bill outflow multiplied by the number of weeks until clients pay. That figure is your funding requirement, and it will rise every time you grow the desk, so plan for the ramp, not just today.
Then check that every charge rate genuinely covers employer NIC, the 12.07 per cent holiday accrual, pension, and a real margin – not just the wage. If any client is priced below that, fix it or drop it. Finally, if you are funding the gap out of your own pocket or a stretched overdraft, get a proper invoice finance facility quoted; it is designed for exactly this shape of business and will almost always free up cash you are currently starving the agency of. Growth is the goal – just make sure your working capital can keep up with it.
