Temp-to-Perm Hiring: When It Works and How to Set It Up

Some roles are hard to fill with confidence. The job is new, the workload may not last, or the skills that matter only show once someone is doing the work. Temp-to-perm hiring lets you bring a person in through a staffing firm for an agreed period, see how they perform and then decide whether to offer them a permanent job.

This guide explains how the arrangement works, when it is a better choice than a direct hire, how conversion fees work and how to set the trial up. It ends with the temp-to-hire terms that 11 staffing firms publish and the questions to ask before you sign.

What is temp-to-perm hiring?

Temp-to-perm, also called temp-to-hire or contract-to-hire, is a temporary assignment that both sides understand may become a permanent job. The person starts on the staffing firm's payroll. If both sides agree to continue, you hire them as your own employee.

Three things set it apart from an ordinary direct hire:

• The staffing firm is the employer during the trial. PrideStaff's hiring FAQ says that for temporary and temp-to-hire assignments, "associates are employed by PrideStaff". Spherion's employer FAQ (opens in a new tab) says it acts as the employer of record for temp-to-hire employees and handles payroll, tax withholding and healthcare benefits that comply with the Affordable Care Act.
• You pay by the hour. TemPositions bills temp-to-hire work "weekly based on employee's hourly rate and hours worked", and PrideStaff bills by the number of hours its employee works at your site.
• Hiring the person early can have a price. PrideStaff and Spherion, for example, work to an agreed number of hours, and PrideStaff charges a pre-negotiated fee to hire before they are complete, as the terms section below explains.

The staffing firm's role as employer does not take you out of the picture. Under the EEOC's 1997 guidance on workers placed by staffing firms (opens in a new tab), a client that supervises the work typically qualifies as an employer of the temporary worker too, so both can be responsible under federal anti-discrimination law. Treat temps with the same care as your own staff, and check state rules with your counsel.

When temp-to-perm works, and when a direct hire is better

The arrangement earns its cost when you genuinely cannot judge the hire in advance. Randstad's employer page (opens in a new tab) puts it simply: flex-to-perm "works best when" you are filling a newly created or evolving role, want a trial period, or need time to evaluate skills, work quality and cultural fit before making a permanent offer. It recommends permanent recruitment when the job's scope is clearly defined or the role is long-standing or strategic. Spherion adds another reason: temp-to-hire can help when you need to delay a permanent hire because of market uncertainty or a fixed budget.

The approach described in this article, shown as a visual guide.

I think about this in terms of which work is core. After two rounds of layoffs in my own business, we built a structure with a full-time core and an hourly flex team, designed so that a fall in revenue meant less hourly work instead of more layoffs. I talked about that structure on the productize.co podcast in May 2025 (opens in a new tab).

Temp-to-perm sits between those two layers. I'd use it for a role that may well become core but has not proved it yet, and I would not use it to avoid deciding about a role you already know you need.

The benefits for employers

• You see the work before you commit. An interview shows how someone talks about a job. A few weeks in the role show how they do it, how they work with your team and whether they are reliable.
• You can respond to demand you cannot forecast. Randstad's flexible-to-permanent page makes the case: if demand stays high, you can hire the people you brought in permanently. If it falls, you have not added permanent headcount.
• The staffing firm carries the employment administration during the trial. Beyond payroll and benefits, Spherion, for example, manages the workers' compensation claim if one of its employees is injured during scheduled work hours.
• A mismatch is easier to fix. The Reserves Network's client FAQ says that if you are not satisfied with an employee, it will replace them, and RedShift Recruiting says a replacement "can be quickly provided".

The drawbacks to plan for

• Compare the total cost of the trial and the conversion. You pay the staffing firm's bill rate for every hour of the trial, and early conversion may add a fee. Ask for the pay rate, the bill rate, the expected hours and any conversion charge, then compare the total with a direct hire over the same period, including recruiting, benefits, payroll costs and onboarding.
• Your best temps may keep looking. A permanent offer elsewhere can be more attractive than a trial with no end date. Tell candidates when you will decide, give regular feedback and make the offer promptly when both sides are ready.
• Some candidates are wary of a temporary start, particularly anyone who would leave a permanent job for it. The Reserves Network offers a variant called DirectSource "for when candidates worry about taking a 'temporary position'", with shorter waiting periods for benefits.
• A trial with no criteria drifts. Without a clear standard and a date, temps stay temporary, your team is unsure how to treat them, and good people leave.
• Your permanent staff notice. Colleagues may invest less in someone they see as temporary. Treat temps as part of the team from the first day.

How conversion fees and trial terms work

None of the 11 firms in the table below publishes a conversion fee percentage on the pages read. What they do publish describes an agreed trial period or number of hours and, at some firms, a fee if you hire before it ends.

How long does the trial last? The length is agreed with each firm. On the pages read, Wide Effect is the only firm to give a typical temp-to-hire range. TemPositions separately says its conversion fee reaches zero after six months.

• TemPositions describes a "reduced fee based on candidate's first year annual salary at time of hire" for temp-to-hire, listed beside its direct-hire price, a one-time fee based on the same first-year salary. Its FAQ (opens in a new tab), checked in October 2026, says the fee falls with the time the person works for you as a temp and reaches zero after six months.
• PrideStaff offers early conversion "before the agreed upon hours have been completed" with a pre-negotiated fee.
• Spherion says that once the contractual hours are met, moving its employee to your payroll is handled by your local representative.
• Randstad says you can hire flexible-to-permanent employees "even before the contract ends".
• Wide Effect's guidance, checked in October 2026, says most of its temp-to-hire engagements last 30 to 90 days, depending on role complexity, operational demands and project timelines.

Before you sign, get these terms in writing:

How to set up a temp-to-perm hire

1. 1

   Write down what the trial must show

   Before anyone starts, decide what success looks like by the end of the trial: the work the person should handle on their own, the standard it must meet and how they should work with the team. I'd keep it to a few lines a manager can check against. If you cannot write it, the role may not be ready to fill.

2. 2

   Tell candidates it is temp-to-perm, and what the decision depends on

   Say from the first conversation that the role may become permanent, roughly when you will decide and what you will base the decision on.

3. 3

   Agree the terms with the staffing firm before the first day

   Settle the bill rate, the trial length, the conversion fee and the replacement terms in the contract. Ask who at the firm will gather feedback during the trial.

4. 4

   Onboard before you evaluate

   Give the person the tools, access, training and manager support the work needs. Explain their role to the existing team and include them in the meetings and feedback that matter. Judge performance once they have had a fair chance to learn the job.

5. 5

   Review at set points

   Hold a short review partway through and another before the trial ends. Give the person the same feedback you give the firm.

6. 6

   Decide on time and convert cleanly

   Make the decision before the trial ends, not after it drifts. If you convert, issue a written offer with the pay, benefits and start date on your payroll, and give the person the same onboarding a direct hire would receive.

Firms that offer temp-to-hire or interim-to-hire

The 11 firms below describe a path from temporary, contract or interim work to permanent employment and publish client evidence on their own sites. Their services, terms and evidence were checked on October 7, 2026. The list is not the whole market: Robert Half, for one, offers contract professionals "with the option to convert them to full-time hires" on its contract talent page (opens in a new tab).

The firms describe different markets. Aerotek, NCW and Wide Effect work in industrial, skilled trades and construction roles, RedShift in technology, and TemPositions through specialist divisions. Randstad, Spherion, PrideStaff and The Reserves Network cover a broad range of operational and office roles. Korn Ferry's route is interim executives and professionals who may stay on.
