How to count full-time employees at peak for a company fit check
Count full-time employees at peak by using payroll history to find the highest number of people the company employed full time at any one point, leaving out contractors, agency temps and part-time staff. SourceX's baseline is 50+ full-time employees at peak (contractors excluded); it is a headcount of people, not a full-time-equivalent calculation.
The short answer: the highest full-time headcount in payroll history
The size test for a SourceX introduction is 50+ full-time employees at peak (contractors excluded). Read each part literally. Full-time means people the company classified as full-time employees on its own payroll. At peak means the highest point in the company's history, not today's number. Contractors excluded means anyone paid as a vendor rather than through payroll stays out of the count.
Peak matters because records accumulate from everyone who ever worked at the company. A business that had 120 employees five years ago and has 40 today may still hold years of email, tickets, CRM history and project files from its larger period. Operating, acquired and wound-down companies can all qualify if the data still exists.
Headcount, FTEs and other counts people mix up
Several common counts answer different questions. Only one of them is the fit check.
| Count | What it measures | Used for | Right for the fit check? |
|---|---|---|---|
| Full-time headcount at peak | Highest number of people classified full-time on payroll | SourceX company baseline | Yes |
| Current headcount | People on payroll today, any status | HR reporting and org charts | No, it misses the peak |
| Full-time equivalents (FTE) | Total hours worked divided by a standard full-time schedule | Capacity planning and some benefits and tax tests | No, part-time hours inflate it |
| ACA full-time employee test | Hours-based definitions under federal health coverage rules | Employer coverage obligations | No, a different legal test |
| SBA research definition | Independent firms below a size line, counted as small | Federal small-business statistics | No, a statistical category |
The SBA's Office of Advocacy, for example, defines a small business for research purposes as an independent business with fewer than 500 employees, which says nothing about full-time status or peaks. Health coverage rules, tax credits and state programs each have their own counting methods; use the specific rule for those purposes and confirm it with a benefits or tax adviser.
How to find the peak from payroll history
A CFO, controller or client accounting team can do this in one sitting without sharing any records.
- Pick the source. Use the payroll system's historical employee roster or its year-end summaries. If the company changed payroll providers, pull history from each one, including files kept in retired accounting systems.
- Filter to full-time status. Use the employment status the company assigned, such as full-time, part-time, seasonal or temporary. Where status was never tracked, apply the company's own full-time definition from its handbook or benefits eligibility rules.
- Remove non-employees. Independent contractors are paid as vendors, and the IRS explains that a business may need to report payments to independent contractors on Form 1099-NEC rather than running them through payroll. Agency temps are paid through a staffing invoice. Leave both out.
- Count at consistent points. Take the active full-time count at each quarter-end or year-end. Quarter-ends catch seasonal peaks that year-end counts miss.
- Take the highest number and note its date, for example 64 full-time employees at the end of the third quarter of a given year.
- Write down only the number. A fit check needs the figure and its date, not names, salaries or a payroll export.
Illustrative example: a fictional regional engineering firm shows 38 full-time employees on its current payroll. Year-end summaries from its previous payroll provider show 57 full-time employees six years ago, before a large contract ended. Its peak full-time headcount is 57, so it meets the size test, and the remaining questions are history, breadth of records and rights.
Edge cases to flag rather than guess
| Case | How to handle it in a fit check |
|---|---|
| Seasonal full-time staff | Count them if payroll classified them as full-time employees on the peak date, and note the seasonality |
| Part-time employees | Leave them out of the full-time count, however many there are |
| Owners and officers on payroll | Count them if they were full-time employees on payroll |
| Long-term contractors who work like staff | Leave them out; classification questions belong with the company's advisers |
| Professional employer organization (PEO) | Use the PEO's worksite employee reports and flag the arrangement during qualification |
| Acquired businesses | Note when the acquired headcount joined and whether the acquired company's records came with it |
| Employees based outside the US | Note them separately and raise them during qualification |
When a case is genuinely unclear, write it down rather than rounding the number up. SourceX confirms size with the company during qualification, and a borderline count raised early saves everyone time.
What the count means for referral partners
For a partner, headcount is the fastest disqualifier and the easiest one to get wrong in both directions. Looking only at today's team page can rule out a company that shrank but still holds a deep history; counting contractors can put forward one that never reached the threshold. A quick check against payroll history avoids both mistakes.
Size is only the first test. The company also needs several years of documented operations, records across many systems, the rights to license them and an authorized sponsor such as the owner, CEO or CFO. The who qualifies page sets out the full baseline, and the company fit checker gives a preliminary, non-binding read with no contact details required. For owners weighing their records alongside other non-core assets a mid-sized company can monetize, the count is the first gate. Old payroll history often sits in retired accounting files, and the guide to old QuickBooks Desktop company files covers keeping them readable.
Limits of this count
- It is a screening threshold for SourceX introductions, not a legal definition of a full-time employee.
- It does not replace employee counts used for benefits, tax credits, state filings or loan covenants.
- A partner shares only the number and its date; payroll records stay with the company.
This is general information, not legal, tax or financial advice. Confirm with your own counsel, tax adviser or professional body before acting.
Next step
Pull the payroll history, write down the peak full-time number and its date, and run the company fit checker. If the company clears the baseline, register as a partner and make the introduction; the fractional CFO referral page explains how the program works for finance advisers.

Common questions
Do contractors count toward the 50 full-time employee baseline?
No. The baseline is 50+ full-time employees at peak with contractors excluded. Independent contractors, freelancers and workers supplied by staffing agencies are left out even if they worked full-time hours for years. If a company only reaches the threshold by adding contractors to its payroll count, it does not meet the size baseline.
Is full-time headcount the same as FTE?
No. Headcount counts people, while full-time equivalents convert total hours into a number of standard full-time schedules, so ten half-time employees become five FTEs. The fit check uses a headcount of people the company classified as full-time employees; part-time staff are left out rather than converted into FTEs.
What if the company is smaller today than it used to be?
Use the historical peak. A company that has shrunk, been acquired or wound down can still qualify if its full-time headcount once reached 50 or more and the records from that period still exist and can be exported. Today's headcount matters for practical questions, such as who can run exports, but not for the size baseline.
Where can I find historical headcount if the payroll provider changed?
Look for year-end summaries or employee census reports from each provider, payroll files kept in retired accounting systems, quarterly payroll filings in the finance team's records and benefits enrollment history. If access to a former provider's portal is about to lapse, download its historical reports first, because rebuilding headcount history later is slow.
Does a partner need to send payroll records to SourceX?
No. Partners give basic fit information only, such as the peak full-time headcount and the year it occurred. Payroll registers, names and salaries stay with the company. If the company goes ahead, SourceX confirms size with the company's own sponsor during qualification, and any detail is shared by the company itself, never by the partner.
