Most mid-sized employers do not decide how many staffing firms to use. They end up with five because a plant manager needed 10 operators in a hurry, finance needed a controller, and sales had a friend who ran an agency. Two years later nobody can say what the total spend is or which supplier actually delivers.
Consolidating to one partner, or a short list of two or three, is a real option. It is also easy to do badly. Here is what it can fix, where it goes wrong and how to decide.
What consolidation actually fixes
Administrative drag. Every vendor means a contract, a rate card, an invoicing cycle, a compliance package and a different person to call. HR and accounts payable absorb that work quietly. Cutting from five suppliers to one or two removes a lot of it, and the saving shows up in hours, not just dollars.
Blind spots in your own data. When hiring is split across suppliers, you cannot easily compare cost per hire, time to fill, early turnover or agency spend by department. One partner reporting in one format makes those numbers visible. Often the first thing a finance team finds is overlap: the same role being filled by two suppliers at different markups, or contract workers kept on far longer than planned.
Inconsistent onboarding. A new hire from one agency gets a proper first-day plan. One from another gets a phone call the night before. A single partner can follow the same steps every time, which matters most in the first 90 days, when early exits cluster.
Weak buying power. Ten small orders spread over six firms earn little attention. Concentrated volume can earn better rates, clearer service commitments and faster access to the recruiter's best candidates.
Where it goes wrong
Consolidation is not free. Know the risks before you sign anything.
- One firm cannot be good at everything. A partner strong in light industrial hiring may be thin on finance or AI and data talent. If you force every search through one door, quality drops in the roles that are hardest to fill.
- Dependence. If your sole supplier has a bad quarter, loses a recruiter or hits capacity, your hiring stalls.
- Rate pressure that backfires. Squeezing a partner on price can push them to send fewer candidates or put their strongest recruiters on other accounts. A fair rate with strong delivery beats a low rate with slow fills.
- Savings claims that do not travel. Vendors like to quote large savings from other clients. Your result depends on your current mess, your volume and your roles. Measure your own baseline first.
A practical way to decide
Start with facts, not preference.
- List every supplier you used in the last 12 months. Include spend, roles filled, contract versus permanent and who owns the relationship internally.
- Measure what you can. Time to fill, share of hires still in seat at 90 days, offer acceptance rate and total spend per function. Even rough numbers will show which suppliers earn their place.
- Group your hiring by type. High-volume production and warehouse work, skilled trades, office and finance roles, sales hires and specialist technical roles behave differently. A good partner for one may not suit another.
- Choose a structure. A single partner makes sense when most of your hiring is similar and steady. A primary partner plus one or two specialists suits companies that hire across several functions. A single partner for everything is rarely right for a company hiring controllers, millwrights and machine learning engineers in the same year.
- Write the terms down. Agree on response times, replacement guarantees, reporting format, how conversions from contract to permanent work and what happens if the partner cannot fill a role within an agreed window. In Canada, confirm how they handle provincial employment standards and worker classification. In the US, check state-level requirements and co-employment questions on contract staff.
What good looks like in practice
One example from our own work: a food manufacturer in the GTA needed over 20 hires in 18 months across production, skilled trades and office roles. Those are three different talent markets. What helped was a single point of contact who understood the plant, steady communication about upcoming needs and consistent screening standards, rather than a new supplier for each opening. The lesson was not that one vendor is always better. It was that continuity and shared planning beat scrambling.
Review it every six months
Consolidation is a decision you revisit. Check the same measures you used at the start. If time to fill is rising, early turnover is up or your partner keeps asking for more time on the same roles, add a specialist or run a competitive search. A partner who is confident in their work will not mind.
What to do next
Pull your supplier list and last year's invoices this week. Total the spend by function and mark which hires are still with you after 90 days. That one page will tell you whether you have a consolidation problem, a quality problem or both.
