A Concrete Example
A consulting firm sends two invoices in the same week. Invoice A: itemized line items, payment terms of Net 15, click-to-pay link, late fee disclosure of 1.5%/month, sent the day work completed. Invoice B: single line “consulting services,” Net 30 implied, sent four weeks after work completed, no late fee mentioned. Invoice A gets paid in 12 days. Invoice B gets paid in 47 days, after two follow-ups.
The difference is not the client — it is the invoice design. Days-to-pay correlates directly with three factors: how quickly the invoice is sent after work completion, how easy payment is (click-to-pay vs. mail a check), and whether late fees are disclosed (psychological signal that delay has cost). The template below builds all three in by default.
What is an Invoice?
An invoice is a commercial document issued by a seller to a buyer that itemizes products or services provided, prices, and payment terms. It’s both a request for payment and a record of the transaction for accounting and tax purposes.
A invoice done badly creates more legal exposure than no document at all, because it puts in writing the misunderstanding that would otherwise have been resolved by a phone call. The template below is one we would actually use ourselves. Free PDF and editable Word.

Frequently Asked Questions
What information must be on an invoice?
At minimum: the word «Invoice», your business info, client info, unique invoice number, issue date, due date, itemized services/products with prices, subtotal, applicable taxes, total amount due, and payment terms.
How should I number my invoices?
Use sequential numbering: INV-001, INV-002, etc. Some businesses include year (INV-2026-001) or client code (CLT-A-2026-001). Stay consistent.
When is sales tax required on invoices?
Sales tax applies when you sell taxable goods or services in jurisdictions where you have nexus. Service businesses are taxable in some states (Texas, Hawaii) but not others. Consult an accountant for your specific situation.
Can I charge late fees on overdue invoices?
Yes, if you specify late fees on the invoice and in your contract. Standard late fees are 1-2% per month. State usury laws cap maximum interest charges.
What’s the difference between an invoice and a receipt?
An invoice is a request for payment (sent before payment). A receipt is proof of payment (issued after payment is received). Both are important business records.
Should I send invoices in PDF or Word format?
Always send PDF to clients. Word/Excel files can be accidentally edited. PDF preserves formatting and looks professional. Keep an editable copy for your records.
How long should I keep invoices?
IRS requires 3-7 years depending on situation. Best practice: 7 years for tax-related invoices, indefinitely for legal/contract documentation.
What if a client refuses to pay an invoice?
First, send polite reminders at 7, 14, and 30 days past due. If unpaid after 60 days, send a formal demand letter. After 90 days, consider collections, small claims court, or hiring an attorney.
Do I need to register a business to send invoices?
You can send invoices as a sole proprietor without formal registration. However, registering as an LLC or corporation provides liability protection and may be required for business licenses in your state.
Should I use invoicing software or a template?
For occasional invoicing (under 20/month), a template works fine. For high volume or recurring billing, invoicing software (FreshBooks, QuickBooks, Wave) saves time and tracks payments automatically.
