How to Start a Professional Staffing Agency: The Complete Playbook
Admin, accounting, legal support, HR, and customer operations: professional and office staffing is the steadiest lane in the industry. Every company in every metro needs these roles, temp-to-hire is a natural fit, and the workers’ comp math is the friendliest in staffing. Here is how to build a desk that compounds.
A professional staffing agency places office and administrative talent (executive assistants, bookkeepers and staff accountants, paralegals, HR coordinators, customer service teams) on temp, temp-to-hire, and direct-hire engagements. It is the classic first agency: modest startup risk, clients everywhere, and a business that grows on reputation. This guide is the professional-staffing companion to our full how to start a staffing agency playbook.
Step 1: Specialize by Function, Then by Level
“Office staffing” is too broad to sell. Pick a function you can evaluate: accounting and finance, legal support, HR, or executive support, and a level band, from coordinators to managers. Function focus is what lets you screen credibly (you cannot vet a senior bookkeeper with a generic interview), and it puts you in referral networks where controllers recommend you to other controllers. Expand functions later; own one first.
Step 2: Set Up Legal, Licensing, and the Friendly Comp Math
Entity, EIN, bank account, and a check of your state’s employment agency rules, which sometimes treat fee-based permanent placement differently from temporary staffing. The good news in this vertical is insurance: office placements ride clerical workers’ comp class codes like 8810, among the cheapest rates in the system, so comp is a manageable line instead of the monster it is in industrial staffing. You still need the policy, plus the general liability clients’ contracts require, before the first start date.
Step 3: Sell to the People Who Feel the Absence
Office roles get backfilled when someone resigns, goes on leave, or a close approaches with the books behind. The buyers are office managers, controllers, HR leads, and practice administrators, and the trigger is a calendar: month-end, tax season, maternity leave, a system conversion. Build your outreach around those calendars, offer temp-to-hire as the default (clients love trying before buying at this level), and treat every placed candidate as a future client, because today’s temp controller is next year’s hiring manager.
Step 4: Price the Mix: Markup, Conversion, and Perm Fees
Professional staffing revenue is a blend. Contract placements run on markup over pay rate with clerical-grade burdens. Temp-to-hire adds conversion economics, and the fee schedule belongs in every agreement before the first hour, structured the way our temp-to-perm conversion fees guide lays out. Direct-hire placements earn percentage-of-salary fees, commonly in the 15% to 25% range depending on level and market. The blend is the strategy: contract revenue pays the bills weekly, conversions and perm fees are the margin kickers.
Step 5: Screen Like the Product Depends on It, Because It Does
In office staffing the product is judgment: the temp who answers your client’s phones or touches their ledger represents you. Build a real screening bar (skills checks for the function, references actually called, software proficiency verified) and onboarding that is airtight: I-9 and E-Verify, background checks where the role and client require them, confidentiality acknowledgments for roles touching sensitive data. One bad front-desk placement costs a client; one bad bookkeeping placement can cost the relationship and your reputation in the referral network you are building.
Step 6: Mind the Cash Gap, Even in the Gentle Vertical
The float math is gentler here than in volume staffing, and it still bites: weekly payroll for your contractors against client terms of net 30 or more, with growth widening the gap. Perm fees help but arrive in lumps and sometimes with guarantee periods. Decide the funding plan at launch, from payroll funding to factoring to a funded EOR, so a great quarter of new placements never becomes a cash crisis.
Step 7: Decide Who Carries the Back Office
Payroll, onboarding compliance, comp and liability coverage, invoicing, collections: it is all real work, and none of it is recruiting. With BOSS it is a per-placement choice: remain the employer on the Core and Funded Plans with the platform automating the back office, or place contractors through BOSS as the employer of record on the Self-Funded EOR and Complete Plans, with employment, insurance, and (on Complete) funding carried by BOSS. Placed employees can even enroll in health, dental, and vision benefits, which wins candidates in a vertical where the talent has options.

Starting a Professional Staffing Agency FAQs
How much does it cost to start a professional staffing agency?
Among the lowest barriers in staffing: modest setup costs, clerical-grade insurance, and a payroll float that grows with placements. The funding plan for weekly payroll against net-30 client terms matters more than startup capital.
How do professional staffing agencies make money?
A blend: markup on contract placements, conversion fees when clients hire temps, and direct-hire fees, commonly 15% to 25% of first-year salary. Contract revenue provides weekly cash flow while conversions and perm fees drive margin.
What comp codes apply to office staffing?
Mostly clerical codes such as 8810, among the least expensive in the workers’ comp system, with outside-facing roles sometimes landing in 8742. Classification still follows actual duties, but the rates make this the friendliest vertical for comp costs.
Is temp-to-hire a good model for office roles?
It is the natural default: clients evaluate real work before committing, candidates try the culture, and the agency earns contract margin plus a conversion fee. The fee schedule must be in the agreement before the assignment starts.
Do office temps need background checks?
Often, depending on the role and client: positions touching finances, personnel records, or sensitive data commonly require them. Build screening and compliant background check consent into onboarding rather than improvising per placement.
Can a solo recruiter start a professional staffing agency?
Yes, and many do: one function, one metro, temp-to-hire default, and the back office handled by a platform or an employer of record so the founder’s hours go to clients and candidates instead of payroll administration.
