Invoice Essentials Checklist

Every invoice should include a few core sections. This checklist helps you avoid missing details that can delay payment.

Business and client detailsNames, addresses, contact infoConfirms who is billing and who is paying
Invoice detailsInvoice number, issue date, due dateKeeps records organized and sets expectations

If your clients require purchase orders, add a PO number field and match line item wording to the PO.

VAT Invoice Requirements (EU and UK Overview)

If you are VAT registered in the EU or UK, your invoices often need additional details. Requirements vary by country, so always check local rules, but most VAT invoices require:
  • A unique, sequential invoice number
  • Issue date and tax point (time of supply)
  • Supplier and customer names and addresses
  • VAT registration numbers
  • Description of goods or services and quantities
  • Net amounts, VAT rate, and VAT amount
The generator includes the standard fields you need and lets you add custom fields for regional requirements.

How to Write Line Items Clients Approve Fast

Clear line items reduce back-and-forth and speed approvals. Keep each line focused on one deliverable or unit of work.

Examples
  • Consulting - Monthly support (10 hours)
  • Design - Brand guidelines (final PDF)
  • Installation labor - On-site (6 hours)
  • Product - Item name or SKU (12 units)
Tips
  • Match wording to your proposal or contract
  • Add dates or service periods for recurring work
  • Separate labor and materials
  • Avoid bundling unrelated tasks

Payment Terms and Due Dates That Reduce Late Payments

Payment terms should be clear and specific so clients know exactly when and how to pay.

Common terms
  • Due on receipt
  • Net 7, Net 14, Net 30
  • Milestone-based payments (for larger projects)
What to list on the invoice
  • Exact due date
  • Accepted payment methods (bank transfer, card, ACH)
  • Late fee policy (only if enforced)
  • Early payment discount (optional)
Clear terms and a visible due date are two of the biggest drivers of on-time payment.

How to Handle Taxes, Discounts, and Shipping

Always itemize adjustments so clients can reconcile your invoice quickly.

Best practices
  • Show the subtotal before taxes and fees
  • List each tax rate separately when possible
  • Add shipping or travel as its own line item
  • Use a discount line instead of altering line item rates
If you sell across regions, confirm which tax rules apply and whether the client is tax-exempt before invoicing.

Invoice Numbering and Recordkeeping

A consistent invoice numbering system makes reporting and reconciliation easier. Many VAT systems require a sequential number, so avoid duplicates or gaps whenever possible.

For recordkeeping, keep copies of invoices and supporting documents. In the US, the IRS generally recommends keeping tax records for at least three years, and longer for some situations.

If you are unsure about retention rules, check local tax guidance for your region.

Common Invoice Types and When to Use Them

Use the right invoice type for the stage of your project.
  • Standard invoice: most common, for completed work
  • Pro forma invoice: estimate sent before work begins
  • Deposit or retainer invoice: upfront payment to reserve time
  • Progress invoice: partial billing for long projects
  • Credit note: refunds or corrections
The generator supports each of these by letting you customize labels, line items, and terms.

Common Invoice Mistakes to Avoid

Even small errors can delay payment. Here are the most common issues and how to prevent them.
  • Missing due date or unclear terms
  • No invoice number or duplicate numbers
  • Vague line item descriptions
  • Taxes applied incorrectly
  • Totals that do not match line items
  • Sending the invoice to the wrong contact

Customize Your Invoice for Your Business

A generic invoice is good, but a tailored invoice gets paid faster. Add fields your clients expect, like:
  • PO number or job reference
  • Service period or billing cycle
  • License or permit numbers (if applicable)
  • Payment instructions and bank details
You can also match your branding with a logo and consistent formatting for a more professional look.
