Once you accept a candidate, a KORE1 contractor starts a median of 3 days later. Across 1,997 placements from 2019 to 2026, 86% started within a week and 37% started the same day. Three in four were working by day five. The data is KORE1’s job-activity report, 79% California, measured from accepted offer to first day.
Ask ten hiring managers how fast a contractor can start and you will get ten answers. Most of them are guesses.
I run recruiting and delivery here, so I get the question weekly, usually from someone weighing a contract staffing engagement against a full-time search because a project date will not move. Most published answers I have seen are a range (“a few days to two weeks”) with no source behind it. We have the actual records, so this post gives the distribution instead, with the sample size and the California weighting stated up front so you can judge for yourself how far it applies to your own role and market.
Contract is not a niche channel, either. The American Staffing Association counts nearly 2.2 million temporary and contract employees working for U.S. staffing companies in an average week of 2024.

Ask ten hiring managers how fast a contractor can start and you’ll get ten guesses. The usual answer is a range, a few days to two weeks, with nothing behind it. We have the records instead. Once you accept a candidate, a KORE1 contractor starts a median of 3 days later. That’s across 1,997 placements from 2019 to 2026.
The median is the headline. The shape underneath it is the part you can plan with. A short wait, and a short tail. Same day, 37%. Median, 3 days. The 75th percentile, 5 days, so three in four were working by day five. And 86% started within a week. The data is 79% California, measured from accepted offer to first day. That’s history, not a promise. Plan around the median and the one-week number, and treat same day as a bonus. A same-day start means everything was lined up before the yes. And we don’t guarantee a start date. Nobody should sell you one.
The clock starts when the candidate accepts and stops on the first day. Inside that window it’s paperwork, access and equipment. The useful question is who owns each piece, because the staffing firm’s half and the client’s half can move at the same time. A start slips when one half sits waiting on the other. The staffing firm handles the background check, the work authorization paperwork and payroll setup. The client handles the laptop, the badge, and accounts and permissions. Those two lists can run side by side.
Four things stretch a start. Approvals, like a purchase order that hasn’t been cut. Background check scope. Equipment that has to be imaged and shipped. And security reviews, which in regulated shops run longest. Three of the four sit on the client’s side. The practical fix is to open the equipment and access requests the day you extend the offer, not the day the candidate says yes. Our records don’t say why any single start ran long, so this is a pattern we see, not something we measured.
Time to fill is the number most buyers quote. It runs from requisition open to offer accepted. Offer to start runs from there to the first day. Different clocks. Our benchmark for IT and tech roles is 17 days to fill. That’s a search figure. The 3 days in this video is a start figure, so don’t add them as if they came from the same placements. How long until someone is working for you is the length of the search plus the length of the start.
If someone can be working in 3 days, who looked at them? Everyone who made the offer. The interviews, references and screening that lead to a yes happen before our clock begins. And the background check has rules. Under the Fair Credit Reporting Act, the employer gives written notice and gets written permission first. Offer to start measures what follows a decision. It’s not a shortcut around one.
Contract wins when the date is fixed and the headcount isn’t. A hard cutover. A close that can’t slip. A backfill during a search. A permanent hire usually owes a current employer notice, often two weeks, before a first day even exists. A contractor can convert to your payroll at no fee after 1,040 hours. Of 552 contract-to-hire placements in our records, 207 converted to a direct hire, or 37.5%. So if the project date is fixed, work backward. Subtract 3 days for the start, then ask how long the search needs for your role and metro. Send KORE1 the role, level, metro and target start date, and we’ll tell you plainly whether the date is realistic.
Three Days at the Median, and the Rest of the Curve
The median is the headline. The shape underneath it is the part you can plan with.
| Offer to start | KORE1 result | Plain-English read |
|---|---|---|
| Same day | 37% | Starts on the day the offer was accepted |
| Median | 3 days | Half started sooner, half later |
| 75th percentile | 5 days | Three in four were working by day five |
| Within 7 days | 86% | About one placement in seven took longer than a week |
Source: KORE1 job-activity report, contract placements dated 2019 to 2026, n=1,997, 79% California, every role family in the records. Measured from accepted offer to first day. Data as of October 2026, refreshed with the January 2027 Contract Rate Index update.
Need someone next week? Start a contract search and send us the role, level, metro, and the start date you are aiming for.
Read the table top to bottom and you get a short wait with a short tail. Simple enough. Our records do not say why any single start ran past a week, and I will not invent a reason for the one-in-seven group. The numbers behind this post show when people started, not what held anyone up.
Two cautions first.
First, the sample is every role family we place, from help desk and accounting to HR and administrative support, and it leans California, so a seat that needs a security clearance or a regulated-industry sign-off is a different animal from an administrative assistant that a blended median quietly hides.
Second, the 37% same-day share is the figure people repeat and the one I would trust least for planning. A same-day start means everything was lined up before the yes. Plan around the median and the one-week number instead, and treat same day as a bonus. Nice when it happens.
And this is history. It is not a promise. Devin Hornick, a partner at KORE1, is blunt about what a contract does and does not carry. “The only SLAs that we have is that our people are going to show up on time, that we’re going to pay them on Fridays… As far as guarantees, there aren’t any. Not on contract.” We do not guarantee a start date, and nobody should sell you one.
What Happens Between the Yes and Day One
The clock in our data starts when the candidate accepts and stops on the first day. Everything inside that window is paperwork, access, and equipment. That is it. The useful question is who owns each piece, because the staffing firm’s half and the client’s half can move at the same time, and a start slips when one half sits waiting for the other to finish. Two owners, one clock.
| Step | Who usually owns it | What it involves |
|---|---|---|
| Background check | Staffing firm | Written disclosure and signed permission before a screening company runs the report |
| Form I-9 | Staffing firm, as the W-2 employer | Employee section on the first day; employer review of original documents within three business days of the hire |
| Payroll and timesheet setup | Staffing firm | Tax forms, pay schedule, weekly timesheet access |
| Laptop, badge, site access | Client | Provisioning, shipping, building or remote setup |
| Accounts, VPN, MFA, permissions | Client | Access requests, usually approved by someone other than the hiring manager |
| NDA and security orientation | Client | Signatures and any required training |
Under the federal Form I-9 rules, the employer can complete its half any time from offer acceptance to within three business days of the hire, which is why paperwork alone need not set the pace. Nothing in the staffing firm’s rows requires the client to lift a finger, so those rows can run alongside the client’s rows instead of ahead of them, provided somebody on each side is watching the same checklist.
A start date, though, is only a date on the paperwork. Nothing more. Whether the person is useful that morning depends on the bottom three rows. Our contractor onboarding checklist walks through the client side in order.
What Slows a Start Down
Four things stretch a start. Three of them sit on the client’s side of the table.
Approvals come first. A purchase order that has not been cut, a vendor onboarding form waiting on procurement, a second signature on a rate. Nobody is dragging their feet on purpose; the request just lives in someone else’s queue. Common, and fixable.
Background check scope is the one on our side, and it is a matter of what you ask for. A basic identity and criminal search clears quickly. Add multiple counties of address history, a degree verified overseas, or a drug screen that needs a lab appointment, and the calendar moves while everyone involved is doing their job correctly. Scope is a choice.
Equipment is mundane and deadly. A laptop has to be imaged, boxed, and shipped, and a remote contractor cannot start in earnest until it arrives. If the machine is not ordered until the offer is accepted, you have already spent your three days. Order it early.
Security reviews are the last one, and in regulated shops they are the longest. A GitHub repository, a Snowflake role, or a NetSuite permission set often needs a separate approval from a team that has never met the contractor, and MFA enrollment in Okta or Microsoft Entra ID waits on the same queue. Plan for it.
I am describing patterns, not measuring them. Be skeptical accordingly. If you want the client-side fixes, the practical one is to open the equipment and access requests the day you extend the offer, not the day the candidate says yes.
Offer to Start Is Not Time to Fill
Time to fill is the number most buyers quote. It counts from the day a requisition opens to the day someone accepts. Offer to start is what happens after that. Different clock.
They are different clocks, measured on different populations, and mixing them is how a vendor ends up promising “start in three days” when what they mean is “three days after you have already chosen someone.” Our own benchmark for IT and tech roles, 17 days from open requisition to filled, lives in our guide to how long it takes to fill a tech role. That is a search figure. The 3 days in this post is a start figure. Do not add them as if they came from the same set of placements.
Here is the honest version of the total. How long until someone is working for you equals the length of the search plus the length of the start. Nothing fancier. A thin candidate pool can take weeks to reach a yes and then start in three days. A deep pool can reach a yes quickly and still lose a week to a laptop shipment.
A Fast Start Is Not a Skipped Check
The worry is reasonable. If someone can be working in three days, who looked at them?
Everyone who made the offer. Whatever interviews, reference checks, and screening lead to a yes happen before the clock in our data begins. Offer to start measures what follows a decision, not a shortcut around one.
The check itself has rules. Under the Fair Credit Reporting Act, an employer using a screening company has to give written notice and get written permission first, as the EEOC’s guidance on background checks lays out. Our background check guide for employers covers the process end to end.
One question worth asking any firm, ours included. How do you confirm that the person on the video interview is the person who shows up on day one? A good answer is specific. A vague one tells you what you need to know.
When Contract Wins on Speed, and When It Does Not
Devin put the case for contract in one breath on a recent planning call. “The contract allows that company to write it off as a CapEx, if they’re working on a development project… you can get them quick… flexible… to scale up, to scale down as needed.” The CapEx treatment is his accounting framing, so check it with your own finance team before you build a budget on it. The speed part is the one our data backs.
Contract wins when the date is fixed and the headcount is not. A hard cutover date. A close that cannot slip. A backfill during a search. A modeled mid-level contract software engineer bills a national median of $108 an hour ($96 to $122), roughly $56,100 for three months at 40 hours a week, per the KORE1 Contract Rate Index (2026-Q4, modeled from BLS wage data and a 24% employer burden).
Permanent hiring starts slower. The reason is plain. A candidate who is employed usually owes their current employer a notice period, often two weeks, before a first day exists at all, and a contractor who is between assignments often does not. If the seat is permanent from day one, direct hire staffing is the right model, at 20% of base salary with a 60-day replacement guarantee, and it is worth the slower start when you are paying for someone to stay for years rather than for a project. Devin’s take is fair. Full-time hiring is “not super flexible,” but you get stability and legacy knowledge.
It can be one decision. A contractor is eligible to convert to your payroll at no fee after 1,040 hours, which is 26 weeks at 40 hours a week, and that conversion right is the reason a contract seat can double as a low-risk trial of a permanent one. Of 552 contract-to-hire placements in our records, 207 converted to a direct hire, or 37.5%. Our post on contract-to-hire conversion rates breaks down what good looks like.
Thinking about January? Booking early is the safer play, and our read on the September temp help numbers explains why. For the budget side, see contractor headcount planning for 2027.
Things Buyers Ask Before Booking a Contractor
How quickly can a staffing agency start a contract worker after I approve them?
At KORE1, a median of 3 days, across 1,997 contract placements from 2019 to 2026, and 86% start within a week.
Approve is the operative word. The clock starts at the accepted offer, so interviews and your decision are not in it. What fills the three days is background check authorization, Form I-9, payroll setup, and your own equipment and access. Our records do not say why a given start ran long, so the client-side pattern I described above is my read, not a measured result.
So how long does it take to get a contractor through an agency, start to finish?
Two stretches of time, and only one is predictable: finding the person, which varies by role and market, and offer to start, a median of 3 days for KORE1 contractors.
We publish the second number because we have 1,997 records behind it. The first depends on how thin the candidate pool is for your stack and metro, which is the part of the conversation where a recruiter earns the fee, and no median can answer it for you.
How fast can an interim CFO start?
We do not publish a CFO-only number. Our all-role median is 3 days from accepted offer to start (n=1,997).
For a senior finance seat, budget your time for the search and the scoping conversation ahead of the offer. Those come first. Our fractional CFO services page explains how those engagements are structured.
Realistically, how long does it take to fill an engineering role?
For IT and tech roles, KORE1’s average time-to-fill is 17 days from open requisition, per our time-to-fill guide. It counts the search only.
Non-software engineering searches run on their own clocks, and senior specialties tend to run longer than the average. The guide breaks the figure out by role.
Does a quick start mean the checks got skipped?
A quick start does not skip the checks, because whatever vetting decides an offer comes before the start clock and the background check follows written-authorization rules.
Same-day starts do happen, 37% of ours, but I would never plan a first-time seat around one. Plan accordingly. And no, we do not guarantee start dates.
Tell Us the Start Date You Need
If the project date is fixed, work backward from it. Subtract three days for the start, then ask how long the search needs for your role and metro. That is the whole plan.
One honest note. If your start date is two months out, you do not need a contract desk to hit it. A standard search will do.
When you are ready, talk to a recruiter about a contract search and give us the role, level, metro, and target start date. We will tell you plainly whether the date is realistic.
