In the UK B2B payment hierarchy, staffing agencies consistently sit near the bottom. Rent, utilities, professional services — they tend to get paid before recruitment invoices. There's a structural reason for this, and understanding it is the first step to fixing it.
UK staffing agencies run average DSO of 45–65 days against agreed terms of 30–45 days. That 15–25 day gap is not random — it's the predictable result of how clients prioritise payments and how most agencies manage collections.
The person who agreed the placement terms often has no involvement in accounts payable. Invoices land in a finance team with no context, sitting in a queue alongside dozens of other supplier invoices. Without an established relationship with AP, staffing invoices are deprioritised — particularly with enterprise clients running 60–90 day terms as standard.
A disputed line item on a staffing invoice can hold up the entire payment — even the undisputed portions. Most agencies don't have a process to separate disputed from undisputed amounts, so one timesheet query freezes £50,000 in otherwise valid claims while the dispute is resolved over weeks.
Most agencies chase invoices after they're already overdue. By then, the client has made a payment decision — other suppliers were paid first. The agencies that consistently get paid on time send reminders before the due date, not after. Pre-due confirmation messages are not chasing — they're professional supplier management.
A credit controller managing 200 active invoices will inevitably let some slip. The accounts chased first tend to be the largest or the ones with the most relationship pressure — not the ones most at risk of going long. Systematic risk-scoring changes this.
If your agency has never charged late payment interest (permissible at 8% + Bank of England base rate under the Late Payment of Commercial Debts Act 1998), or has never enforced payment terms consistently, clients learn that late payment carries no real consequence. The agencies with the best DSO enforce consistently — even symbolically.
| Metric | UK Staffing Average | Equisettle Clients (3 months) |
|---|---|---|
| Agreed payment terms | 30–45 days | 30–45 days |
| Actual DSO | 45–65 days | 30–47 days |
| DSO gap vs terms | 15–25 days | 0–5 days |
| Credit control time per week | 3–4 days | Under 2 hours |
| Collection rate | ~85% | 92–97% |
At £500,000 monthly revenue, each additional day of DSO ties up approximately £16,500 in working capital. For agencies funding weekly contractor pay before clients settle, this is not an abstract finance metric — it's directly constraining growth.
| Monthly Revenue | DSO Reduction | Working Capital Freed |
|---|---|---|
| £250,000 | 15 days | ~£125,000 |
| £500,000 | 15 days | ~£250,000 |
| £1,000,000 | 15 days | ~£500,000 |
For agencies using an invoice finance facility, faster collections reduce drawdown directly — lowering the cost of the facility. For agencies self-funding contractor pay, it's the difference between a comfortable cash position and a weekly funding squeeze.
The agencies with consistently low DSO don't have better clients — they have better processes. Specifically:
"The WhatsApp reminders made the biggest difference. Clients respond to those within the hour. Our DSO dropped 18 days in two months."
