Freelance Accounting: How to Price and How to Handle Several Clients

This is written for accountants who want to work independently, or to take on a few files alongside a permanent job. It focuses on the three areas where most mistakes happen: pricing, defining scope, and running several clients at once during the crowded months.

Why mispricing is the usual problem

Most newly independent accountants copy a price from the market without knowing what services that figure covers. They sign a flat monthly fee, and then tax defence, year-end close and responding to an assessment all get added on top with no extra income. The issue is not the price; it is the scope.

Price on workload and risk

Company size is a poor indicator. A high-turnover trading company may generate a hundred documents a month while a small shop generates a thousand. Use these drivers to estimate hours instead.

Driver Why it matters
Monthly document count The most direct driver of posting time
Payroll headcount Volume of payroll and social security work
Warehouses and sales points Complexity of stock control and reconciliation
VAT registration Periodic returns and input credit control
Bank accounts and cash funds Reconciliation time
Open tax files Risk and defence time
Quality of incoming documents The biggest hidden driver of all

Do not underestimate the last row. A client who hands over organised, complete documents takes half the time of one who arrives with a bag of receipts. Give new clients a one-page guide on how to hand over documents at the first meeting, and reference it in the contract.

Calculating your floor rate

  1. Write down your target annual income.
  2. Add annual fixed costs: software, internet, travel, training, office.
  3. Add an estimate of your own tax and insurance.
  4. Count real working weeks after holidays and leave.
  5. Estimate billable hours per week realistically, usually about sixty per cent of working hours.
  6. Divide the total of steps 1 to 3 by total billable hours to get your floor rate.
  7. Estimate monthly hours per client and multiply by the rate.
  8. Add ten to fifteen per cent for unplanned work.

Billable hours are not working hours. Marketing, chasing payment, training and your own admin are unavoidable and generate no invoice, so they have to be carried in the rate.

Pricing models

Model Suits Main risk
Fixed monthly retainer Steady recurring work Volume creeping up without a price adjustment
Hourly Unclear projects, advisory, clean-up work Client resistance, needs accurate time records
Fixed-price project Year-end close, system implementation, tax defence Underestimating scope
Tiered by document volume Growing clients Needs a transparent counting mechanism
Hybrid retainer plus project fees Most real engagements Requires a precise contract

In practice the hybrid works best: a monthly retainer for routine work, plus separate fees for the annual return, assessment defence and special projects.

Put the scope in writing

Most fee disputes come from unclear scope. At a minimum, make these explicit:

  • What the monthly fee includes and, just as importantly, what it excludes.
  • The document volume the price assumes and the mechanism for adjusting it.
  • The client's duty to deliver documents on time and the effect of their delay on your deadlines.
  • Whether attending an assessment meeting is inside the fee or priced separately.
  • Data and software ownership, and full handover at the end of the engagement.
  • Confidentiality and termination terms on both sides.

Tax-sensitive contract clauses are covered in contracts from a tax perspective, and the client view of your pricing is worth understanding from outsourced accounting versus hiring.

Never accept custody of cash, cheque books or payment authority. Your role is recording and reporting; control over assets stays with the client.

Running several clients

The constraint in Iran is rarely client count; it is simultaneous deadlines, since annual filing seasons hit every file at once.

  1. One calendar: every deadline for every client in a single calendar, not scattered files.
  2. One routine: the same chart of accounts logic, folder structure and report template across clients, to reduce mental switching.
  3. Capacity sized on peak season: measure your limit against the busiest filing month, not a quiet one.

Build a fixed monthly reporting template, modelled on the monthly management report. A standard template cuts your time and makes the value of your work visible to the client.

Your own tax position

Professional service income is business income with its own obligations: registering a file, keeping income and expense records, and filing annually within the deadline. Corporate clients may withhold tax on your fee and issue a certificate, which is credited against your final liability. Foreign-currency and overseas clients raise separate issues. If your own turnover is small, simplified filing forms may also be available, on conditions announced each year.

When to raise your price

  • When a client's volume has grown twenty to thirty per cent above the contracted basis.
  • When an out-of-scope service has quietly become a monthly habit.
  • At the start of each year, at least in line with the inflation in your own costs.

Announce increases in writing a few weeks ahead and include a summary of what you delivered over the past year. Clients rarely object to an increase that arrives with evidence of work behind it.

Key takeaways

  • Price on workload and risk, never on company size.
  • Derive your floor rate from target income and genuinely billable hours.
  • A hybrid retainer plus project fees fits most engagements.
  • Unclear scope is the single biggest source of disputes and unpaid work.
  • Size capacity around peak season and keep your own filings in order.

Frequently asked questions

What should accounting fees be based on?
Workload and risk, not company size. The practical drivers are monthly document count, headcount on the payroll list, number of warehouses and sales points, VAT registration, and whether tax defence is inside the scope. Estimate the hours, then apply your target rate.
How do I calculate my own hourly rate?
Divide your target annual income by genuinely billable hours, not by total working hours. In practice around sixty per cent of a freelancer's time is billable; the rest goes to marketing, collections, training and admin. Add fixed costs and your own tax before dividing.
How many clients can one person handle?
It depends on the mix. One person can usually run several small files with limited documents, but more than two or three heavy files with active inventory and large payrolls costs quality. Size your capacity around the crowded filing months, not the quiet ones.
Should I charge in advance?
For recurring work, billing at the start of the period removes most collection problems. For one-off projects such as an audit defence or a year-end close, part on start and part on delivery is normal. Put the amount and timing in the contract.
What are my own tax obligations?
Income from professional services is business income with its own obligations: registering a file, keeping income and expense records, and filing an annual return on time. Corporate clients may withhold tax on your fee and give you a certificate, which is credited in your final settlement.
