- Add Your Payment Terms: Explain how to pay and include the engagement reference.
How to Fill In Professional Service Invoice Line Items
Show the units behind each fee. Use hours for time-based work and a quantity of one for a fixed meeting or task. Separate tasks only when your agreement prices them separately.
This fictional bookkeeping engagement uses USD. Entry review, account reconciliation and the meeting have separate agreed prices. This example applies 8% tax to all three services. Use the tax treatment that applies to your own work.
| QTY | Description | Unit Price | Amount |
|---|---|---|---|
| 4 | Bookkeeping entry review — hours | $75.00 | $300.00 |
| 2 | Account reconciliation — accounts | $95.00 | $190.00 |
| 1 | Monthly summary meeting — fixed fee | $85.00 | $85.00 |
| Subtotal | $575.00 | |
| Sales Tax (8% example) | $46.00 | |
| Total | $621.00 |
What to Include in Professional Service Invoice Terms
Use Terms and Conditions to identify the engagement and billing period. State when payment is due and where the client should send billing questions.
For an ongoing fee, name the period and services covered. Use the payment terms already agreed with the client. Replace the bracketed details in this example before sending.
Example: Terms and Conditions
- This invoice covers [Professional Services] for [Engagement Reference] during [Billing Period].
- The fees follow the agreed hourly, fixed-fee or ongoing-service arrangement.
- Payment is due on [Due Date] by [Accepted Payment Method].
- Please include [Invoice Number] with payment. Send billing questions to [Billing Contact].
Bill for the Services You Provided
Use the service description and fee you agreed. Docelf calculates the invoice total. Send the bill with the reference your client needs.
Show How You Charged for the Service
Use the billing method you agreed with the client. A fixed fee does not need to become an hourly charge to fit the template.
Hourly Work
Name the tasks and work dates. Show the hours and rate. Attach a time summary when the client needs more detail than fits on the invoice.
Project Fee
Name the project, stage or deliverable covered by the fixed fee. Do not add hours already included in that price.
Retainer or Ongoing Service
State the billing period and the work covered. Make clear whether you are billing a current service fee or applying an earlier payment.
Appointment or Session
Use the appointment date and an appropriate service description. Keep private case or treatment details out of the billing summary unless they are necessary.
Explain Expenses Without Adding Private Case Details
List approved travel, filing fees, materials or outside services separately from your professional fees. Describe what each expense relates to so the client can check it against the agreement.
Attach a work summary when the client needs more detail. Include only information appropriate for the invoice recipient; do not copy a full case or treatment record into a bill.
You can create an invoice from an estimate or professional service quote in Docelf. Review the copied client details and fees for the work you are billing now.
Choose a File for Professional Billing
Use Word or Google Docs for flexible service descriptions. Choose Excel or Google Sheets for several time entries, rates or expenses.
Keep Track of the Client's Payment
After emailing the invoice from Docelf, check its history to see whether the client received and opened it. Include the project or service reference in any follow-up.
Record the payment against the invoice, then create a receipt to confirm the amount received. Check the remaining balance before requesting another payment.
Need Another Service or Billing Format?
Browse a related industry, a different billing type or a file format. Keep the choice tied to what your client needs to see.
