After a difficult stretch for recruiters, the UK temporary hiring market is showing signs of life again.
The latest KPMG and REC UK Report on Jobs, published in August 2026, found that temporary vacancies increased for the first time in two years. Temp billings also continued to rise, with growth remaining among the strongest recorded since early 2023.
For recruitment agencies, that is welcome news. More demand for temporary workers means more placements and potentially more revenue. It also creates a less obvious challenge: every new contractor adds another stream of timesheets, approvals, pay calculations, expenses and invoices that somebody has to process.
Winning new business is only half of the scaling problem. Agencies also need a back office capable of keeping up with it.
A Placement Creates More Work Than It Appears
Recruitment technology discussions tend to concentrate on the front office. Applicant tracking systems, candidate sourcing platforms and artificial intelligence all promise to help recruiters find and place people faster.
Those developments matter. We recently looked at how modern talent acquisition software is combining applicant tracking, automation, reporting and AI to make hiring more efficient.
Temporary and contract recruitment, however, does not end when a candidate accepts an assignment.
Once someone starts work, the agency has another workflow to manage. Hours need to be recorded correctly, the client has to approve them, different rates or overtime rules may apply, contractors or temporary workers need to be paid and the client needs to be billed.
With ten active contractors, teams may be able to manage much of that manually. With a hundred, small inefficiencies start multiplying.
The Spreadsheet Problem Usually Appears Gradually
Spreadsheets remain useful because they are flexible, familiar and cheap. A new recruitment agency can build a workable process around Excel, email and an accounting package without making a major technology investment.
The problem is not necessarily the spreadsheet itself. It is the number of manual handoffs that begin to surround it.
While one person downloads approved hours, someone else could have to check rates. Then, data is transferred to payroll, but another version is used to prepare client invoices. Consultants chase missing submissions by email. Finance then has to work out which records have already been processed.
This is a common technology problem beyond recruitment. Operational issues often emerge at the points where work moves between people, departments and systems.
Recruitment agencies face exactly that challenge. The more contractors they place, the more frequently information has to move from worker to client, agency, payroll and finance.
Pay and Bill Becomes a Scaling Issue
For a temporary recruitment business, timesheets are not simply records of attendance. They sit close to the centre of the commercial process.
Approved hours determine what a worker should receive and what the agency can invoice. That makes delays or errors more consequential than ordinary administrative inconvenience.
This is where specialised timesheet platforms for recruitment agencies starts to become relevant. Instead of treating time capture, approvals, contractor payments and invoicing as separate tasks, agencies can connect them into a single workflow.
These platforms can allow workers to submit hours digitally, route them to the appropriate client for approval and then use the approved information further along the pay-and-bill process. Depending on the system, the same workflow can also accommodate expenses, overtime rules, payroll exports and client invoicing.
The important point is not simply replacing paper timesheets with online forms. Digitising a bad process only makes the same process digital.
The larger benefit comes when approved information can continue through the business without employees repeatedly copying, checking and re-entering it.
Automation Works Best on the Predictable Parts
Recruitment is still fundamentally a people business. Clients want consultants who understand their requirements, while candidates value recruiters who know their market and communicate well.
Back-office administration is different.
Sending a reminder because a timesheet has not been submitted does not require much human judgement. Neither does routing an approval to the correct manager or transferring already verified data into an invoice.
These are repetitive, rules-based tasks—the kind most suited to automation.
The distinction matters because agencies sometimes approach growth by adding administrative capacity every time contractor numbers increase. That works, but it can create a back office whose cost rises almost in parallel with revenue.
A more scalable model tries to separate exceptions from routine work. Software handles predictable transactions, while employees intervene when something genuinely needs investigation: a disputed timesheet, an unusual rate, a rejected expense or a client-specific billing issue.
That allows operations staff to spend more time resolving problems and less time moving information between systems.
Integration Matters More as the Technology Stack Grows
Recruitment agencies rarely operate with one piece of software.
A typical technology stack might include an ATS or CRM for candidates and placements, separate onboarding tools, a timesheet platform, payroll systems and accounting software. Larger businesses may add reporting and business intelligence tools on top.
Each product can work perfectly well individually while the overall process remains inefficient.
That is why integration becomes increasingly important as an agency grows. Creating a contractor in one system should not necessarily mean manually creating the same person again somewhere else. Likewise, information that has already been approved should ideally flow into downstream processes without being re-keyed.
The objective is not to buy as much software as possible. It is to reduce the number of times employees have to move the same information manually.
That also makes system selection a workflow question rather than just a feature comparison. Agencies need to understand what happens from the moment a placement is created to the moment the worker is paid and the client invoice is issued.
Growth Can Expose Weak Processes Very Quickly
A slow market can hide operational weaknesses because staff have enough capacity to compensate for them manually.
A faster market does the opposite.
If temporary hiring continues to improve through the second half of 2026, agencies could find themselves handling more placements without much warning. Processes that felt perfectly manageable at one contractor volume may become bottlenecks at another.
That makes the current improvement in temporary recruitment more than a sales opportunity. It is also a useful stress test.
Agencies that expect to grow can map where information is entered, who approves it, where employees still rely on spreadsheets or email, and which tasks repeatedly require chasing. Those friction points reveal where additional volume is likely to cause problems first.
The agencies best positioned for the next rise in temporary hiring may therefore be the ones looking beyond how quickly they can make placements. The more important operational question is what happens after every successful placement—and whether the systems behind it can absorb the next hundred contractors as comfortably as they handled the first ten.
