Monthly bookkeeping retainer
The most common structure for bookkeepers. A fixed monthly fee covers a defined scope — categorizing transactions, reconciling accounts, and delivering reports. Invoice at the beginning of the month you're covering, not after.
| Description | Amount |
|---|---|
| Monthly bookkeeping — July 2026 Up to 150 transactions, 3 bank accounts, monthly P&L and balance sheet | $450.00 |
| Payroll processing — July 2026 4 employees, bi-weekly. Includes filing 941s and state withholding. | $200.00 |
| QuickBooks Online subscription (pass-through) Simple Start — billed at cost, receipt on file | $35.00 |
| Total due | $685.00 |
Tax preparation billing
Tax prep fees vary by return complexity. Bill per return type, not hourly — clients hate not knowing what they'll owe. For complex returns, include an estimate upfront and bill the balance on delivery.
| Description | Amount |
|---|---|
| Federal tax return preparation — Form 1040 Tax year 2025. Includes Schedule C (sole proprietor), Schedule SE. | $650.00 |
| State return — California (Form 540) Prepared concurrently with federal return | $150.00 |
| Tax planning session (1 hour) Q4 2025 review, estimated payments, S-corp election analysis | $200.00 |
| Retainer deposit received — March 15, 2026 | −$400.00 |
| Balance due on filing | $600.00 |
Hourly advisory billing
For clean-up projects, CFO advisory, business formation, or any work that can't be scoped in advance. Attach a time log with dates and brief task descriptions — clients receiving advisory invoices expect this level of detail.
| Description | Hours | Rate | Total |
|---|---|---|---|
| Books clean-up — 18 months of uncategorized transactions Jan 2024 – Jun 2025 reconciliation and categorization | 14.0 | $150 | $2,100.00 |
| S-corp formation advisory Entity structure analysis, reasonable salary calculation, implementation guide | 3.0 | $200 | $600.00 |
| Total due (17 hrs) | $2,700.00 |
What to include on an accounting invoice
Your business name and credentials
Include 'CPA', 'EA', or 'Certified Bookkeeper' — it reinforces the value of your service
Client's legal business name and EIN/SSN
For business clients; helps their AP team match your invoice to vendor records
Tax year or billing period
For tax prep: 'Tax Year 2025'. For bookkeeping: 'For services rendered July 1–31, 2026'
Specific return types or service scope
Not just 'tax preparation' — specify Form 1040, Schedule C, state return, etc.
Invoice number and date
Essential for your own records and for client reimbursements or deductions
Due date
Net 15 for bookkeeping retainers, due on delivery for tax returns works well
Payment method
Bank transfer, check, or credit card — many accounting clients still pay by check
Late fee notice
Especially important during tax season when your capacity is maxed out
6 invoicing rules for freelance accountants
Invoice tax prep clients upfront with a deposit
Tax season creates enormous concentration risk — 60% of your annual revenue in 12 weeks. Get a 50% deposit when clients sign their engagement letter in January. This also filters out clients who aren't serious about filing on time.
Never deliver a completed return before payment clears
A completed tax return is immediately usable. Unlike advisory work, you can't take it back. Hold the signed return and e-file authorization until payment has cleared — not just been promised.
Bill bookkeeping retainers at the start of each month
Bookkeeping is a forward commitment — you're allocating capacity for that client's work in the coming month. Invoice on the 1st, just like a software subscription. Monthly billing on the 1st also makes your revenue predictable and your cash flow smooth.
Separate software subscriptions from your fee
If you bill QuickBooks Online or any other subscription through your invoice, line-item it separately at cost. Bundling it into your fee creates confusion when clients ask to compare your rate to another bookkeeper.
Charge for additional document requests
Tax clients who deliver disorganized records mid-process, request amended returns, or need additional correspondence with the IRS after filing — these are out-of-scope services. Document your scope clearly and charge for anything outside it at your hourly rate.
Use engagement letters, not just invoices
An invoice alone is not a contract. A signed engagement letter defining scope, timeline, client responsibilities (delivering documents by a certain date), and fees protects you from disputes. Your invoice then becomes the payment request for agreed services, not the document that defines what's included.

Frequently asked questions
Should accountants charge sales tax on their services?
In most US states, professional accounting and bookkeeping services are not subject to sales tax. However, some states do tax certain digital services. If you're delivering cloud-based bookkeeping through a software platform, check your state's rules. Consult a local tax attorney or CPA if you're unsure — the rules change, and the irony of an accountant being surprised by a tax audit is best avoided.
What's the best payment method for accounting clients?
ACH bank transfer is the most common for business clients — low fees, traceable, and expected by AP departments. Check is still standard with smaller, older businesses. Avoid accepting cash for tax-season payments — it creates a documentation gap. Credit card is fine for individual tax clients if you build the processing fee into your pricing (2.5–3%).
How do I invoice for an amended return?
Treat it like a new service, not a correction to your previous work — especially if the amendment is necessary because the client failed to provide complete information the first time. Bill at your hourly rate for the time spent, with a brief note explaining what changed and why. Most clients understand this if it's been discussed upfront.
Can I invoice clients for IRS correspondence on their behalf?
Yes — representing clients before the IRS (for enrolled agents) or responding to basic notices (for bookkeepers, depending on your credentials) is a billable service. Bill hourly and document exactly what correspondence was handled and when. Always clarify in your engagement letter that IRS representation is not included in your base retainer.
What payment terms should accountants use?
For bookkeeping retainers: due on the 1st of the month, before services begin. For tax prep: 50% deposit at engagement signing, balance due on delivery of the completed return. For hourly advisory: Net 15 from invoice date. These terms front-load payment relative to your work, which is especially important during the concentrated revenue period of tax season.
