How to Invoice as a Bookkeeper: Rates, Terms and Templates

Bookkeeping clients pay without questions when the invoice mirrors the engagement letter. The monthly fee should look the same every month, and anything that makes a bill bigger (a backlog, a new bank account, January's 1099s) should be visible as a separate line with the count behind it. Most small-business owners are not accountants, so plain descriptions matter more than jargon.

This guide covers the billing models bookkeepers use, a complete invoice with real arithmetic, timing and terms, the scope lines that prevent disputes, and what InvoiceQuickly can and can't do for a bookkeeping practice. For setting the prices themselves, see how to price accounting services.

How do bookkeepers bill clients?

Most bill a fixed monthly package for routine work and charge separately for anything outside it. The package is defined in the engagement letter by what drives the work: the number of transactions, bank and card accounts reconciled, entities, and reports delivered. That definition is what makes later invoices easy to defend. When a client's volume jumps from 150 to 300 transactions a month, the invoice can point to the cap they agreed to.

Hourly billing suits work you can't scope in advance: a cleanup of records nobody has touched for a year, diagnosing a payroll mismatch, or teaching a new office manager the software. Many bookkeepers quote catch-up work as a fixed fee per month behind once they have seen the records, and hourly before they have.

Per-unit fees suit work that scales by count: year-end forms, additional entities, extra accounts. They keep the monthly package stable while the invoice still reflects the real workload.

For context, the US Bureau of Labor Statistics reports a median pay of $50,670 a year, or $24.36 an hour, for employed bookkeeping, accounting and auditing clerks in May 2025 (BLS Occupational Outlook Handbook, accessed 27 October 2026). That is an employee wage. A self-employed bookkeeper's rate also has to cover unbilled admin time, software, insurance, self-employment tax and the months between clients, so it is normally well above that figure.

What should a bookkeeping invoice include?

Every invoice needs your business name and contact details, the client's legal business name and address, a unique invoice number, the invoice date, a description of each service, quantities and rates, the total, the due date and how to pay. The checklists in what to include on an invoice and how to write an invoice cover these.

For bookkeeping, add:

• The period on every line: "October 2026 close", "Catch-up: July to September 2026".
• The package scope in one line, so overage lines make sense on sight.
• The entity the work was for, if the client owns more than one business. Better still, invoice each entity separately so each company's books record its own expense.
• Filing references for any filing support you billed, plus the jurisdiction (for example, the state for a sales tax return).
• Pass-through costs at cost, such as a software subscription you pay on the client's behalf, labelled as such.
• A short memo on what was delivered and what you are waiting for from the client.

Worked example: an October close invoice

Hypothetical example. The rates are this bookkeeper's contract rates, not market benchmarks. A freelance bookkeeper works for a coffee shop, Harbor Coffee LLC. The engagement letter sets a monthly package of $650 covering up to 200 transactions, two accounts reconciled (one bank account and one card) and a monthly profit and loss statement. Each additional account reconciled is $60 a month. Catch-up work is $85 an hour. Terms are Net 15.

In October the owner opened a PayPal business account for online orders, and the bookkeeper also cleared a backlog from July to September that the previous bookkeeper had left. The invoice goes out on Thursday 5 November 2026, the day the October reports are delivered.

Due date: Friday 20 November 2026 (Net 15).

Memo: "October books closed and reports sent 5 Nov. Catch-up for July to September complete; 3 card transactions over $500 still need receipts (list attached to the reports email). From November, PayPal reconciliation is part of the monthly package at $60. Next close needs bank statements by 5 Dec."

Why it works: the package line is identical to every other month, so the client's eye goes straight to the two lines that are new. The catch-up line shows the date range and hours, so it can't be mistaken for a permanent price rise. The memo records an outstanding client responsibility without a separate chasing email.

In January the same client's invoice would add a per-form line, for example "Form 1099-NEC preparation and filing, tax year 2026: 6 forms × $30 = $180". For payments made in 2026, the 1099-NEC threshold for nonemployee compensation is $2,000, and copies are due to recipients and the IRS by January 31 (IRS, Instructions for Forms 1099-MISC and 1099-NEC, accessed 27 October 2026). Collect W-9s during the year so January's count is known in advance.

When should you send the invoice, and on what terms?

Monthly work: send the invoice with the close, usually in the first week of the following month. The client receives the reports and the bill together, which ties your fee to something they can see. If a client is new or has paid late before, bill the package in advance on the 1st and the extras in arrears.

Catch-up projects: invoice at milestones, such as each quarter of backlog reconciled, rather than at the end of a project that may run for months. A deposit before you start is reasonable when the size of the backlog is unknown; quote it as an estimate first.

Filing support: invoice right after the filing, with the confirmation or reference number on the line.

Terms: Net 15 or Net 30 are both common; pick one and put it in the engagement letter and on every invoice. Short terms suit monthly work because the next close comes round quickly. If you charge a late fee, state it in the engagement letter and on the invoice, and check your state's rules first in late fee laws by state.

Whether you must charge sales tax on bookkeeping depends on your state, so check with your state's revenue department rather than relying on a general list.

What are you not allowed to call yourself or do?

Keep your titles and invoice descriptions within what you are licensed for. In the US, anyone who prepares federal tax returns for pay must have a preparer tax identification number (PTIN). A preparer with only a PTIN can prepare returns but cannot represent clients before the IRS; enrolled agents, CPAs and attorneys have unlimited representation rights (IRS, understanding tax return preparer credentials and qualifications, accessed 27 October 2026). "CPA" and audit or review work are regulated by state boards of accountancy. So an invoice line such as "IRS audit representation" from a bookkeeper without those credentials is a problem; "Prepared transaction records for your CPA's audit response" is not.

In the UK, businesses providing accountancy services need anti-money-laundering supervision. HMRC supervises accountancy service providers that are not supervised by a professional body, and bookkeeping bodies such as the Institute of Certified Bookkeepers are on the list of supervisors (GOV.UK, money laundering regulations: who needs to register, accessed 27 October 2026).

Rules last checked 27 October 2026. This is general information, not legal or tax advice.

Which invoicing mistakes cost bookkeepers money?

• No transaction cap in the package. Without one, a client whose volume doubles gets twice the work for the same fee, and there is nothing on the invoice to point to.
• Catch-up work hidden inside the monthly fee. The client thinks the first three bills are the normal price, or that a later normal bill is a discount. Keep backlog on its own line with its date range.
• One invoice for several companies. Each entity should record its own bookkeeping expense. Separate invoices, or at least a subtotal per entity, save the owner's accountant a job at year-end.
• Software costs folded into labour. If you pay for the client's subscription, show it as a pass-through line at cost so the client can see it and drop it if they take the subscription over.
• Scope creep from a new account or entity. Add the line the month it starts and say so in the memo, before it becomes a habit you are doing for free. The scope creep guide covers the conversation.
• Wrong client legal name. Accounts payable teams reject invoices addressed to a trading name. Check the legal name on the client's W-9 or company record once a year.

How InvoiceQuickly fits a bookkeeping practice

InvoiceQuickly is for sending invoices for your own bookkeeping fees. It is not practice-management or accounting software.

Available now:

• Line items with quantity and unit price, so hours (9.5), forms (6) and units sit on separate lines with their own rates.
• Notes and terms fields for the memo and your payment terms, and a default payment term you set for your business.
• Record full or partial payments (bank transfer, check, card, cash or other) and see the remaining balance, on every plan.
• On Pro ($9/month): email delivery with the PDF attached, scheduled reminders before and after the due date, a private client portal, estimates for quoting catch-up work, credit notes, CSV export and Stripe or PayPal payment links on your own account.
• On Pro, a recurring schedule can create the monthly package invoice. The schedule form creates one line item with saved payment terms (30 days by default) and the saved tax and discount rates, and it can't be edited after you create it. Leave auto-send off and each month's invoice waits as a draft, so you can add that month's extras and change the terms before sending.
• On Pro, time tracking with a timer or manual entries, and billing selected unbilled time and expenses into one draft invoice you review.
• On Business ($19/month), a reviewed, one-way export of invoices you select to your own practice's QuickBooks Online company or Xero organisation, with account, item and tax mapping. It never emails clients or records payments there.

Not available:

• No connection to your clients' own QuickBooks or Xero files, or to other accounting software. Pro's CSV export moves invoice data into your own workflow; it has no amount-paid or balance column, so reconcile receipts from your bank records.
• No timesheet approvals for staff.
• No file attachments on outbound invoices, document portal for client records, e-signatures or deadline management.
• One business per account, so it bills your practice's fees, not invoices on behalf of your clients' businesses.

The Free plan covers 5 invoices in total and up to 5 clients. A client with three LLCs invoiced separately uses three of those five client records, so a practice with more than a couple of clients will need Pro. See pricing, or start free to try the editor. The for accountants page covers the fit for small practices in more detail.

When this approach doesn't fit

• You run a firm with staff, timesheets and deadlines to manage. A practice-management platform with timesheet approvals and filing-deadline tracking will save more time than an invoicing tool.
• You bill clients through their own accounting software. If your clients expect invoices to arrive inside their own QuickBooks or Xero, InvoiceQuickly can't do that; its Business export goes only to your own company.
• Your work is mainly tax preparation or representation. The credential and engagement rules above matter more than invoice layout; see a professional body for engagement letter guidance.

Start from the bookkeeper invoice template or the recurring invoice template, and compare an annotated layout in the accounting invoice example. If you also run your own business books, accounting basics for freelancers covers your side. More guides are on the blog.

Frequently asked questions

How do bookkeepers bill clients?

Most charge a fixed monthly package defined by transaction volume, accounts reconciled and reports, and bill anything outside it separately: catch-up work hourly or per month behind, year-end forms per form, extra accounts or entities per unit. The monthly invoice shows the package line plus any extras with their counts.

Should I charge per transaction or a flat monthly fee?

A flat monthly fee with a transaction cap gives the client a predictable bill and you a clear trigger for a review. Set tiers (for example up to 200, 201 to 400) in the engagement letter and name the current tier on the package line so a move to the next tier is expected, not a surprise.

When should I send a bookkeeping invoice?

With the month-end close, so the client receives reports and the invoice together. Bill new or previously late clients in advance on the 1st instead. Invoice catch-up projects at milestones and filing support right after each filing.

What is a bookkeeper not allowed to do?

In the US, a bookkeeper without a PTIN can't prepare federal tax returns for pay, and one without CPA, enrolled agent or attorney status can't represent clients before the IRS. Calling yourself a CPA or performing audits requires a state license. In the UK, an accountancy service provider needs anti-money-laundering supervision from HMRC or a professional body.

Do I invoice separately for each entity a client owns?

Yes, ideally. Each company should record its own bookkeeping expense, and separate invoices make that automatic. If the client insists on one invoice, give each entity its own lines and subtotal.

Can InvoiceQuickly send invoices into my clients' QuickBooks or Xero?

No. InvoiceQuickly doesn't send invoices into a client's QuickBooks or Xero. On the Business plan it can export invoices you select to your own QuickBooks Online company or Xero organisation, one way, after you map accounts, items and tax rates. Otherwise it sends your invoice as a PDF by email (on Pro) or for you to download, and Pro's CSV export lets you bring invoice data into your own records.
