Free Invoice Template for Accountants

How accountants usually bill

Bookkeeping is normally a fixed monthly fee scaled to transaction volume and account count. Tax preparation is per return, priced by entity type and complexity, with schedules and additional states as add-ons. Advisory, representation, and clean-up work is hourly. Payroll runs per pay period plus per employee. Filing fees paid to a government agency are pass-through and should never sit inside your fee.

What belongs on a accountant invoice

Beyond the obvious — your details, the client’s details, a total — these are the fields that a generic invoice template leaves out and that accountants need:

• Engagement letter reference and the period or tax year covered
• Each service as its own line — bookkeeping, payroll, tax prep, advisory are not one thing
• Form numbers and tax years for preparation work, which clients need for their own records
• Hours and rate for anything billed hourly, including clean-up work
• Government filing fees and third-party costs at cost, clearly marked as pass-through
• Out-of-scope work identified as such, referencing the engagement letter

Deposits, terms, and when to invoice

Monthly recurring work bills in advance on a fixed date. Tax preparation is commonly billed on delivery, before the return is filed or released — the profession's usual practice, and worth stating in the engagement letter so it is not a surprise in April. Clean-up work on new clients should take a deposit; it is almost always larger than either party expected. Net 15 is reasonable for a professional service with a signed engagement letter behind it.

Tax and pass-through costs

Accounting and bookkeeping services are untaxed in most US states, though a handful tax them and a few more tax data processing broadly enough to reach some bookkeeping arrangements. Government filing fees are pass-through, not revenue, and should be shown at cost. Independence and fee-arrangement rules — including restrictions on contingent fees for certain engagements — come from your professional standards rather than tax law, and the invoice is where those arrangements become visible. General information, not tax or legal advice.

Line items that prevent arguments

Each of these is a real dispute that a single line on the invoice makes impossible to have:

• "This is more than last year" — separating tax prep from clean-up and advisory shows exactly which part grew.
• "I thought that was included in the monthly fee" — an out-of-scope line referencing the engagement letter closes it without a conversation.
• "Why am I paying a filing fee to you?" — marking it pass-through at cost makes clear it is the state's money, not yours.
