For most of the staffing industry's history, growth has had a simple and slightly unforgiving shape. More roles meant more recruiters, more recruiters meant more desks, managers and overhead, and revenue rose in a fairly straight line with headcount. That model worked well enough when demand was predictable and hiring good recruiters was the main constraint. It works much less well in a market like this one.
Staffing Industry Analysts now expects the US staffing market to grow 2.4% in 2026, describing a return to "broad-based, although moderate expansion" after three difficult years. That's welcome news, but moderate growth is a tricky environment to staff for. Hire ahead of demand and margins suffer if the recovery stalls. Hire behind it and the desks you have are stretched, response times slip, and clients notice. The agencies that will come out of this period strongest, in our view, are the ones that break the link between delivery capacity and headcount, so they can take on more roles without adding people at the same rate.
That's what we mean by lean delivery. It isn't about running with fewer recruiters, and it certainly isn't about squeezing the ones you have. It's about removing the work that never needed a recruiter in the first place, so their time goes on the parts of the job that actually win business.
Where delivery capacity really goes
Ask most agency leaders what their recruiters spend the day doing and you'll get a reasonable answer: sourcing, screening, speaking to candidates, managing clients. Ask the recruiters to track it for a week and the picture is usually quite different. A great deal of the day goes on coordination: reformatting CVs, copying candidate details from one system into another, building shortlists in spreadsheets, emailing profiles to hiring managers, chasing feedback, and updating the ATS afterwards so there's a record of what happened.
None of those tasks is hard on its own. The cost is in the volume and in the switching between them. Research published in Harvard Business Review found that workers toggled between applications roughly 1,200 times a day, adding up to just under four hours a week spent reorienting after each switch. Recruiters, who often move between an ATS, email, LinkedIn, a CV editor, a spreadsheet and a messaging app within a single shortlist, are about as exposed to that as any profession we can think of.
The opportunity is significant. McKinsey estimates that talent acquisition accounts for around 20% of generative AI's value potential across HR, and that people could spend up to 60 to 70% less time on administrative work that can be automated. We'd be cautious about treating any single figure as a target, but the direction is hard to argue with: a large share of delivery time is spent on work that a well-designed system could do.
Why more tools hasn't made agencies leaner
The natural response to all this has been to buy more software. An AI sourcing tool here, a CV formatter there, a scheduling app, a chatbot, a reporting dashboard. Each one solves a real problem, and each one also adds another tab, another login and another handoff.
The American Staffing Association's research on recruiter productivity makes a point we think is often missed: top-performing recruiters use around seven or eight tools, chosen for specific purposes, and more technology doesn't by itself mean higher productivity. What separates high performers is that their tools address actual workflow problems. In other words, the stack matters less than how the work flows through it.
This is why we think the conversation about recruitment process automation needs to shift from tasks to handoffs. Automating one step in isolation, formatting say, saves time on that step and then often loses it again at the next one, when a perfectly formatted profile sits in an inbox waiting for someone to send it. Lean delivery comes from connecting the steps, not just speeding them up individually.
Eight principles of lean agency delivery
1. Map delivery as one workflow. Write down every step from receiving a brief to a hiring manager making a decision, including the invisible ones: chasing, copying, re-entering, checking. Most agencies have never seen their delivery process drawn end to end, and the bottlenecks are usually obvious once it is.
2. Keep the ATS as the system of record. Your applicant tracking system is where candidate and client records belong, and replacing it is rarely worth the disruption. But an ATS was built to record work, not to run it. The day-to-day motion of getting from brief to shortlist needs a system of work that sits above the record.
3. Automate the handoffs, not just the tasks. The moments where work passes from one person or tool to another are where time disappears. A shortlist that moves straight from screening to formatted profiles to a hiring manager's review, without anyone forwarding files, is worth more than any single task done faster.
4. Work in batches. Recruiters process candidates one at a time largely because their tools were designed that way. Bulk actions, applying the same screening criteria, formatting or outreach to a whole shortlist at once, are one of the simplest ways to increase capacity per recruiter.
5. Standardise the output. Every candidate profile that leaves the agency should look like it came from the same firm, regardless of who produced it. Consistent, branded candidate presentation isn't only a brand question. It removes rework, reduces client queries and makes quality something the system guarantees rather than something individuals have to remember.
6. Close the hiring manager loop. In our experience, the single biggest source of lost time in agency delivery isn't on the recruiter's side at all. It's the wait for feedback after a shortlist goes out. Giving hiring managers one place to review candidates and respond turns an open-ended wait into a visible, trackable step.
7. Govern how AI is used. Your recruiters are almost certainly using AI already. Gartner found that 69% of cybersecurity leaders have evidence or suspect that employees use public generative AI at work. Lean delivery at scale depends on that usage happening in a sanctioned environment, where candidate data is protected and the output is consistent, rather than in personal accounts the agency can't see.
8. Measure flow, not activity. Calls made and CVs sent tell you how busy people are. Time from brief to shortlist, time from submission to hiring manager feedback, the ratio of submissions to interviews, and roles handled per recruiter tell you whether delivery is actually getting leaner.
The multi-ATS reality
One practical complication deserves its own mention. A lot of agencies, particularly those that have grown through acquisition or operate across regions, run more than one ATS. Workforce management software, CRM and back-office systems add further layers. Any approach to scaling without headcount has to work across that landscape as it actually is.
That's why we'd be wary of automation that only functions inside a single vendor's ecosystem. It can work well for an agency that runs entirely on one platform, but it tends to create new silos for everyone else, and it makes future changes to your stack much harder. The more durable approach is an orchestration layer that sits above whichever systems you already run. It's also why Allsorter, our candidate presentation product, integrates live with Bullhorn, JobAdder, Vincere, Mercury, Tracker and Salesforce.
Where Allsorter Nexus fits
Allsorter Nexus is a chat-driven recruitment workflow platform built for exactly the coordination layer this guide describes: the stretch between receiving a brief and delivering a shortlist that most agencies have filled with tabs, spreadsheets and manual effort.
Recruiters work in a chat interface, and Nexus runs the workflow behind it. Screening and shortlisting happen in one place. Candidate presentation is powered by the same Allsorter formatting engine that more than 400 recruitment agencies already use. Flows let recruiters run bulk actions across an entire shortlist rather than one candidate at a time. The Hiring Manager Portal gives clients a single place to review candidates and leave feedback. Your ATS stays the system of record, and Nexus becomes the system of work above it. Allsorter and Nexus are both covered by our ISO 27001 certification and built to GDPR standards, so the efficiency doesn't come at the cost of control over candidate data.
The outcome we're designing for is simple to state. A recruiter should be able to handle more roles, at a higher and more consistent standard, without working longer hours, and an agency should be able to grow delivery without growing headcount in step.
A 90-day starting plan
Days 1 to 30: see the workflow. Map delivery end to end for two or three representative desks. Ask recruiters to log where their time goes for a fortnight. Identify the three handoffs where work waits longest.
Days 31 to 60: fix the biggest handoff. Choose the single bottleneck with the most impact (for most agencies it's either candidate presentation or hiring manager feedback) and pilot a connected workflow on one desk. Agree the measures up front: time to shortlist, time to feedback, roles per recruiter.
Days 61 to 90: standardise and extend. Turn what worked into the default process. Set agency-wide standards for candidate presentation and AI use. Extend to further desks, and review the measures monthly.
Lean delivery isn't a single project. It's a change in how an agency thinks about capacity, from something you buy by hiring to something you build by designing better work. The agencies that make that shift during a period of moderate growth will be well placed when the market picks up properly.

Frequently asked questions
What does staffing agency scalability mean?
It's an agency's ability to take on more roles and clients without costs, especially headcount, rising at the same rate. Scalable agencies increase the capacity of each recruiter rather than relying only on hiring more of them.
How can a staffing agency scale without adding headcount?
By removing coordination work from recruiters' days: connecting delivery steps into one workflow, automating handoffs between systems, using bulk actions, standardising candidate presentation and giving hiring managers a single place to review and respond.
What is recruitment process automation?
It's the use of software to handle repeatable steps in the recruitment process, such as screening, CV formatting, candidate communication and status updates. It's most effective when it connects steps together rather than speeding up tasks in isolation.
Do we need to replace our ATS to automate agency delivery?
No. The ATS works best as the system of record. A workflow platform such as Allsorter Nexus sits above it to run day-to-day delivery, while the ATS continues to hold candidate and client records.
