Average Office Administrative Services Revenue per Year 2022 Economic Census

The 2022 Economic Census counts every office administrative services firm with paid employees and publishes their combined annual receipts. Dividing one by the other gives the average annual revenue per employer establishment below.

≈$2,412,000 /year

Average annual gross revenue per employer establishment

37,646

Employer establishments in the United States, 2022

as published $90.8 billion

Combined annual gross revenue of employer establishments, 2022

How this is calculated: about $90.8 billion in combined annual receipts divided by 37,646 employer establishments works out to an average annual revenue of $2,412,000 per employer establishment. This category covers administrative support rather than the operating decisions of the client business.

Scope: Office Administrative Services, NAICS 561110. Nothing outside that code is counted on this page.

Five years on, this industry group counted about 53 establishments aged five for every 100 that first reported paid employment in 2018. Census compares counts by age rather than following the same businesses, so read it as a broad continuation indicator for the industry group, not as a tracked survival rate.

Across the 2014 to 2018 cohorts, five-year results ranged from 52.3 to 54.5 percent. This category is effectively the whole group: 37,646 of the 37,646 employer establishments in it, so the group figure and the category figure describe nearly the same population. A count by age is not a survival rate, because the figures compare two headcounts rather than follow one set of businesses.

Payroll as a Share of Revenue Official data

Payroll divided by receipts, both as published for the same year.

MeasureValue
Annual payroll share of receipts, United States≈45%

Payroll share of receipts, Office Administrative Services, United States, 2022 Economic Census.

Approximately 45.0 percent of every revenue dollar goes to annual payroll, which is high because staff time is essentially the entire product.

Payroll here excludes benefits, employer taxes, payments to contractors and owner compensation, so the full cost of delivering the service sits above this share.

Business Scale and Ownership Structure Official data

How large the average establishment is, and whether the population is independent operators or multi-site companies.

MeasureValue
Paid employees per employer establishment14.9
Employer establishments per firm1.09

Scale and ownership, Office Administrative Services, United States, 2022 Economic Census.

The average establishment employed about 14.9 people, and the industry counted 1.1 employer establishments per firm.

These are arithmetic industry averages. They state the size of the average establishment and show that multi-establishment ownership exists. They do not show the distribution of business sizes and they do not measure market concentration.

Questions Worth Asking BusinessNES analysis

Office Administrative Services: where the figures stop being useful.

Before you rely on this benchmark

  • What does the client list look like? Client concentration is a leading risk in this trade: a firm built around two large clients can lose half its revenue in one conversation.
  • Is the work retained or project based? A monthly retainer and an implementation project produce the same receipts very differently, and only one of them is predictable.
  • What is the staff utilization rate? Administrative work is sold as staff time, so unbilled hours are the difference between a good year and a poor one.
  • How much is delivered offshore or remotely? Delivery location can change the cost base substantially and is invisible in a national revenue average.
  • How easily could the client bring this in house? Some administrative functions may be brought back in-house when switching costs are low, so the relationship needs continual justification.
  • Where does the process knowledge live? Undocumented work lives in the heads of individual staff, and their departure can become a client crisis rather than a staffing one.

Sources and Methodology

Revenue, establishment counts, payroll, employment and firm counts on this page come from the 2022 Economic Census, Summary Statistics, published by the US Census Bureau. Averages and shares are BusinessNES calculations from those published totals, and each one names the two figures it divides.

The Census counts employer establishments, meaning each staffed office rather than each client contract.
