Recruitment Agency Software: What a Small UK Agency Actually Needs

A five-person agency and a fifty-person agency rarely need the same software, yet vendor guides tend to describe one stack as if it suits everyone.

This guide is for UK agency owners and heads of growth who are choosing or replacing a system. It covers what to buy, what to leave until later, and the UK compliance points that should shape the decision. It is a decision framework rather than a league table, because the right answer depends on your size, your desk mix and how you find candidates.

Last reviewed 30 October 2026. The legal points come from ICO and GOV.UK guidance, linked at the end. This is general information, not legal advice.

The short answer

Four points to carry through the rest of this guide:

• Buy a recruitment-specific ATS with a CRM built in. A tool designed around one employer’s vacancies has no concept of clients, fees or terms of business.
• Judge each tool by the daily work it saves your consultants, and ignore the length of its feature list.
• Check retention, deletion and data export before you sign. They are hard to fix once you have loaded ten thousand records.
• Plan for the gap above the ATS. It stores candidates but does not find them or start the conversation.

ATS and CRM: what each does for an agency

An ATS (applicant tracking system) records candidates and moves them through the stages of a job. A CRM (customer relationship management system) records your relationships with clients and candidates over time: who you spoke to, what was said and when to follow up. In-house teams usually need only the ATS side. Agencies need both.

For an agency the two jobs overlap, which is why recruitment-specific products combine them. Your database is your stock. Every client call, candidate screen and speculative CV send has to land on the same record, otherwise two consultants end up phoning the same hiring manager in the same week.

Generic in-house ATS tools are built around one employer’s vacancies. An agency works across many clients, each with its own vacancies, fee terms and supplier rules. Agency-focused systems add client records, job orders, CV submissions and placements, and temporary or contract desks also need timesheets and invoicing. One vendor guide to small-agency ATS selection lists an integrated CRM for clients and job orders among the features to prioritise (Bullhorn UK). It is a vendor page, so weigh its product claims accordingly, but that point holds up.

A common mistake is buying a standalone ATS and a separate sales CRM, then paying a consultant’s time to keep them in step. If you do run two systems, test the sync with 50 real records before you commit.

Spreadsheet-and-inbox set-ups work for a solo recruiter placing a few roles a quarter. They stop working when a second consultant joins, because nobody can see who has spoken to whom.

Features that matter at 1 to 10 and 11 to 50 consultants

Up to ten consultants, simplicity wins. Each extra module is something a consultant must learn, and the ones who find a system fiddly stop logging activity, which defeats the purpose of buying it. Between eleven and fifty, permissions, reporting depth and integrations start to earn their cost.

Two features sit outside this table because they cost extra and tempt buyers early: built-in AI matching and workflow builders. Both can help, but neither fixes a database that consultants do not update. Fix the logging habit first.

What sits on top of the ATS: sourcing and outreach

An ATS holds the people you already know about. Filling a live job usually means contacting people you do not know yet, and no ATS does that for you. The work breaks into three steps: finding the right profiles, sending connection requests and messages, and handling the replies. Consultants skip it in busy weeks because it is slow and the reward arrives late.

There are three ways to cover it:

• Consultants do it by hand between calls. This costs the least cash and the most billable time.
• The agency runs its own LinkedIn outreach tool. This is cheaper than hiring, but someone must own the set-up, the messaging and the account safety. LinkedIn restricts automation software, so check any tool against LinkedIn’s rules before you connect an account.
• An outreach partner runs the activity for you. RecruitRev Talent Outreach works this way: we run outreach to candidates for your live jobs and interested candidates land in your consultants’ inbox. Screening and submission stay with your team.

Whichever route you choose, test the hand-off to the ATS. When a candidate replies to say they are interested, does that reply end up on their record with the job attached, without anyone copying and pasting? If not, you will either lose replies or spend consultant time re-keying them. Ask each software vendor, and any outreach provider, to show you that flow using your own data.

The same gap exists on the business development side, where someone has to find hiring managers and start conversations. Client Outreach covers that for agencies that would rather spend their time on the calls that follow.

UK compliance: what your software must help you do

Software does not make you compliant. You are responsible for how you use candidate data, and the system either helps you or gets in the way. Guidance from the ICO and GOV.UK turns into specific features to look for:

• Privacy information on time. Where you use publicly available information for your own purposes, you should give people privacy information as soon as possible and within one month of obtaining it (ICO, finding candidates). Look for notice templates and a log of when each one went out.
• Direct messages count as direct marketing. The ICO treats direct messaging on social media as electronic mail under PECR, so those rules cover candidate outreach (same page). Check how opt-outs are recorded and respected across your ATS and any outreach tool.
• No keeping data just in case. Agencies usually cannot rely on consent to hold candidates for future roles, and the ICO says to keep information only if you intend to use it and have told candidates how long you will hold it (ICO, data protection and recruitment). You need retention rules, bulk deletion and an audit trail.
• Records you must keep, and produce quickly. Agencies must keep records of applications from hirers and work-seekers for at least one year from when you last provided services to them, and must hand records to an inspector by the end of the second business day after a request (GOV.UK). Your system should hold records for the right period and export a full history within hours, not weeks.
• Care with AI. The ICO expects a data protection impact assessment before high-risk processing, which it links to using AI or automated decision-making in recruitment, and it advises avoiding tools that risk discrimination (ICO, data protection and recruitment, above). Ask any vendor with matching or scoring features how it works and what evidence they hold.

How to choose: seven questions and a two-week trial

Shortlist two or three systems, then put each through the same questions. Write the answers down, because demos blur together by the third call.

1. Can I export all of my data in a usable format if I leave, and does that cost extra?
2. How long is the contract, what is the notice period, and what happens to price at renewal?
3. Does email and calendar activity log against records automatically?
4. How do retention rules, deletion requests and subject access exports work in practice?
5. Can I see pipeline and placements by consultant without building a spreadsheet?
6. Which job boards, payroll tools and outreach tools does it connect to, and which of those connections cost extra?
7. Where is the data hosted, and which sub-processors does the vendor use?

Then run a two-week trial with real data rather than the vendor’s sample records:

• Import 200 of your own candidate and client records and check for duplicates and broken fields.
• Have every consultant log a full day of activity, and ask them what slowed them down.
• Send a real candidate reply through the full flow from inbox to record to job.
• Run one subject access export and one deletion on a test record.
• Pull the report your managing director will want at month end.

Compare quotes in pounds, per user per month, with set-up, training and add-ons itemised. Pricing varies widely between vendors and changes often, so rely on a current written quote rather than any figure in a guide, this one included.

Frequently asked questions

What is the best recruitment software for a small agency?

There is no single best system. The right choice depends on whether you place permanent, temporary or contract roles, how many consultants you have and which tools you already use. Pick an agency-specific ATS with a built-in CRM, then compare two or three options using the questions above.

Do I need both an ATS and a CRM?

You need both functions. Recruitment-specific systems usually combine them, so you buy one product. A separate sales CRM only makes sense if your business development team needs features the built-in one lacks, and then the two systems must sync reliably.

Is free recruitment software good enough?

It can work for a solo recruiter testing a niche. Check user limits, data export and whether the free tier includes the retention and deletion tools you need for UK GDPR, because those are the hardest features to add later.

How much does recruitment agency software cost?

Vendors usually charge per user per month, with extra fees for set-up, training, job board posting and integrations. Ask for a written quote in pounds that itemises each element, and ask what the price becomes at renewal.

Does using recruitment software make me UK GDPR compliant?

No. You remain responsible for how you collect, use and delete candidate data. Software can help with notices, retention and deletion, but you still need the policies and habits to match. The ICO’s guidance for recruiters is a good place to start.

Can AI tools screen candidates for me?

They can support screening, but the ICO expects a data protection impact assessment before high-risk processing, which it links to using AI to help make recruitment decisions, and it advises avoiding tools that risk discrimination. Keep a person making the final decision.

Next steps

Shortlist two systems, run the trial above and decide within a month. Once your database is in order, the next constraint is usually how many new conversations your consultants start each week. See how RecruitRev runs outreach for UK recruitment agencies.
