Recommended Free Tools
For a polished service-business invoice, choose a free Word or Google Docs template if your work needs detailed written descriptions, Excel or Google Sheets if you need repeatable line items and calculations, or PDF when you want a stable copy to send or print. Customize it to show who is billing whom, what work was done, how the total was calculated, and when and how payment is due.
Choose a template format that fits your workflow
Free invoice templates are available in several common formats. Smartsheet lists Word, Excel, PDF, Google Docs, and Google Sheets options, including service invoice templates. The format affects how easily you can edit descriptions, calculate totals, and send a fixed copy.

| Format | Best suited to | Practical consideration |
|---|---|---|
| Word or Google Docs | Invoices with narrative descriptions, project milestones, or custom notes | Flexible to edit, but check calculations yourself. |
| Excel or Google Sheets | Multiple line items, hours or quantities, and repeated calculations | Review formulas and totals before sending. |
| A stable copy for sending or printing | Keep an editable source file if you may need to revise the invoice. |
For Microsoft Office, free pre-built templates can be opened from File > New and customized. See Microsoft’s template instructions. Smartsheet’s invoice template collection includes editable and printable options.
What a professional-services invoice should show
Choose a service-specific layout that makes the work and amount due easy to understand. QuickBooks’ professional-services template highlights hours, rates, amount due, and payment terms; other template examples include invoice numbers and dates, customer details, discounts, and tax rates.
#1 Best Overall
- Two-Part Carbonless Invoice Book: Each invoice book has 50 sets of invoices, each with a white/light yellow section, with the yellow section retained in the invoice book to maintain detailed records.
- Consecutively Numbered: Enlarged red 6-digit numbers in the upper right corner of each invoice receipt book help you quickly navigate through your orders.
- Wraparound Divider Flap: A thick folded cardboard divider is integrated into the back of each invoice book for use between each two-part sales order to prevent the written content from rubbing off on subsequent copies of the invoice, resulting in wasted invoices.
- 2 Packs/50 Sets (100 Sets Total): Each invoice book provides 50 sequentially numbered carbonless sets of 2 invoice books for long-term use.
- Customizable Space: Each invoice book for small business has space at the top to add a company seal or sticker.
- Business and client details: Names and relevant contact or billing information.
- Invoice tracking: A unique invoice number and the invoice date.
- Work performed: A clear service description and, where useful, the date or period covered.
- Calculation: Hours or quantity, rate per hour or unit, and each line amount.
- Total: Subtotal, any discount, applicable tax, and the total due.
- Payment instructions: Due date, accepted payment method or instructions, and agreed payment terms.
Adapt the fields to the engagement and the rules that apply where you and your client do business. A template is a starting point, not proof that an invoice meets every local tax, sales-tax, VAT, or electronic-invoicing requirement.
Prepare and send an invoice
- Select the file type. Use a document format for descriptive work, a spreadsheet for calculations and repeated line items, or PDF for a fixed version to deliver.
- Replace the sample details. Enter your business and client information, invoice number, and date. Remove fields that do not apply, and add any that your transaction or local rules require.
- Describe the services and calculate the amount. Add the work or service period, hours or quantity, rate, and line amounts. Check the arithmetic, discounts, and any applicable tax.
- State payment terms clearly. Include the due date and payment instructions that match your agreement with the client.
- Review and retain a copy. Verify names, dates, totals, and readability. Save the sent invoice and related records in a system you can use to track business income and expenses.
Keep invoices in a usable recordkeeping system
For U.S. businesses, the IRS says, “You may choose any recordkeeping system suited to your business that clearly shows your income and expenses.” The IRS generally does not require a special record format, but records should support income and deductions. Electronic records must provide a complete and accurate record accessible to the IRS. See the IRS guidance on recordkeeping and recording business transactions.

Those U.S. recordkeeping points do not establish that any particular template satisfies every requirement. Retention and invoice rules depend on the record, transaction, and jurisdiction. Businesses outside the United States should check their local tax authority’s requirements.
Do not confuse invoice design with 1099 reporting
For covered nonemployee-service payments made during calendar year 2026, the IRS identifies a $2,000 Form 1099-NEC reporting threshold. This is a payer information-reporting rule for that payment year, not a minimum invoice amount, a required invoice field, or a general invoice-format rule. Check the IRS page for the applicable year and payment circumstances: Form 1099 and other information return requirements.

QuickBooks provides downloadable invoice templates and an invoice generator; compare the features you need before choosing a tool.
