Most owners and hiring managers add a second or third staffing agency for the same reason: a role is open, the first agency has not filled it, and more lines in the water feel like less risk. Sometimes that is the right call. Often it is how a company ends up with five agencies, no clear picture of any of them, and the same open requisitions it started with.
This post sets out what actually goes wrong with a crowded vendor list, when a smaller list works better, and when it does not.
What a crowded vendor list costs you
The appeal of many agencies is simple. More sources should mean more candidates and faster fills. In practice, a few things get in the way.
- Recruiters stop prioritizing your roles. When an agency knows it is one of five on a requisition, it is a race. The recruiter puts effort where the odds of being paid are best, and your search drops down the list.
- Candidates get shopped. The same person shows up from two agencies, or a strong candidate hears about your role three different ways. That reflects badly on you, not on the agencies.
- Your message gets inconsistent. Each agency describes your company, pay and culture in its own words. Some get it wrong.
- Pressure on price pushes down quality. If agencies compete mainly on fee or markup, the cheapest way to compete is to send less-screened people faster.
- You cannot see what is working. Numbers sit in separate inboxes and spreadsheets. Nobody can say which source produces people who stay.
The result is hiring that reacts to each vacancy instead of planning for the next six months.
What consolidating gets you
A single partner, or a short list of two or three with clear lanes, changes the dynamics.
- Better briefs. A recruiter who works with you repeatedly learns your plant floor, your team leads and your pay bands. Screening gets sharper with each hire.
- One set of numbers. Time to submit, interview-to-offer ratio, offer acceptance, 90-day retention. When one partner reports these consistently, you can act on them.
- Less admin. One contract, one point of contact, one set of compliance and onboarding steps. For a small HR team, that matters.
- A steadier candidate experience. People hear the same story about your company every time.
- Planning becomes possible. A partner who knows your seasonal peaks, expected attrition and growth plans can build a bench before the requisition opens.
There is a trade-off. You depend more on one firm, so that firm has to be good. Consolidating onto a mediocre partner just concentrates the problem.
When many agencies still make sense
A single partner is not always right. Keep more than one when:
- You hire across very different fields, such as skilled trades, accounting and software, and no one firm is strong in all of them.
- You recruit in several regions or in both Canada and the US and need local market knowledge.
- You have a rare search that needs a specialist for a limited time.
- You are testing a new partner and want a fair comparison before committing.
The point is not the number. It is whether each agency has a defined role, a fair shot at the work and an agreed way of reporting results.
A practical way to decide
Pull the last 12 months of hiring and sort it by source. For each agency, look at:
| Measure | What to look for | Red flag |
|---|---|---|
| Submittal quality | Share of candidates you interview | Most resumes are rejected |
| Fill rate | Roles filled vs. roles assigned | Many searches go quiet |
| Retention | Still employed at 90 days and 12 months | Early exits cluster with one source |
If you cannot build this table because the data does not exist, that is your answer. The first step is getting visibility, with or without fewer vendors.
Then ask three questions:
- Which agencies understand our business well enough that we spend less time explaining each search?
- Which ones tell us when a role is unrealistic, rather than sending anyone to look busy?
- Where do we repeat the same hiring every year, such as production staff, seasonal accounting help or sales development reps?
Repeat hiring is where consolidation pays off first. One food manufacturer in the GTA worked this way, with a single partner supporting over 20 hires in 18 months across production, skilled trades and office roles. The value was not any one fill. It was that each search started with what the last one had taught.
How to move without disruption
Do not cut everyone on the same day. Pick the roles you hire most often, give one partner exclusivity on them for a defined period, and set the measures up front. Keep a backup for urgent or unusual searches. Review after a quarter, and widen or narrow the arrangement based on results.
What to do next
Start with the source-by-source review of your last year of hires. It will show you where you are paying for noise and where one partner could do more. If you want a second view on the numbers or on which roles to consolidate first, a Traverse recruiter can help with that.
