Invoice Template Generator for Small Business — Free PDF, VAT & Multi-Currency (2026)

Why Small Businesses Overpay for Invoicing Software

FreshBooks starts at $19/month. QuickBooks at $35/month. Invoice Simple at $20/month. Wave embeds ads in your invoices. Stripe requires a developer.

For a small business sending 10–50 invoices per month, none of this is necessary. A professional invoice requires:

• Your business details and logo
• Your client's details
• Line items with quantities and prices
• Tax calculation
• Payment terms

That's it. Everything a $35/month subscription does, a free browser-based tool can do just as well.

TooStamply's Invoice Generator handles all of this — free, with no account required.

What a Complete Small Business Invoice Must Include

A legally valid invoice for most jurisdictions requires:

Required Elements

For VAT-Registered Businesses

Add your VAT registration number (EU, UK, Australia, Canada). Without it, your client cannot reclaim the VAT — and they'll ask for a corrected invoice, causing payment delays.

For US Businesses

Include your EIN (Employer Identification Number) on formal invoices. While not always legally required, it's standard practice for B2B invoicing and is needed if clients issue 1099 forms.

Invoice Numbering Best Practices

Sequential Format (most common)

INV-0001
INV-0002
INV-0003

Year-Based Format (for annual record-keeping)

2026-001
2026-002
2026-003

Client-Based Format (for multiple clients)

ACME-2026-001
JONES-2026-001

Never reuse invoice numbers. This creates accounting confusion and can cause issues with VAT compliance audits. TooStamply auto-increments invoice numbers — you just set the starting point.

VAT and Tax: How to Handle It Correctly

EU VAT Rules

• VAT must appear as a separate line item on every B2B invoice
• Include your VAT registration number and your client's VAT number for EU cross-border invoices
• The VAT rate depends on the service type and customer location (OSS rules for digital services)

UK VAT (Post-Brexit)

• Same format requirement: VAT as a separate line, VAT number on invoice
• UK VAT numbers start with "GB"

US Sales Tax

• Rules vary by state and county
• Many states exempt services from sales tax but require it on physical goods
• Some states (Oregon, Montana, Delaware, New Hampshire) have no sales tax at all

Australia GST

• 10% GST applies to most goods and services
• Must show GST amount separately on tax invoices over AUD $82.50

TooStamply supports two independent tax lines per invoice. Add "VAT 20%" and "Local tax 2%" as separate lines — totals calculate automatically.

Multi-Currency Invoicing for International Clients

Sending invoices in your client's local currency:

• Reduces friction — no currency conversion for the client
• Speeds up payment — clarity on exact amount due
• Looks professional — shows you understand international business

Supported Currencies (50+)

USD, EUR, GBP, JPY, CAD, AUD, CHF, INR, BRL, MXN, SGD, HKD, NOK, SEK, DKK, NZD, ZAR, AED, and many more.

Currency Note Best Practice

Include a note on foreign currency invoices:

*"Amount in EUR. Based on EUR/USD rate of 1.08 as of [invoice date]. Payment should be made in the invoiced currency."*

This prevents disputes about exchange rate fluctuations between invoice date and payment date.

Choosing the Right Invoice Template

How to Follow Up on Unpaid Invoices

Day 1 (Invoice sent)

Send the invoice with a friendly note: *"Please let me know if you have any questions before the due date."*

Day 30 (Due date)

If unpaid: *"This invoice is now due. Please let me know if payment is on its way or if you need another copy."*

Day 37 (+7 days late)

More direct: *"Invoice INV-0042 is 7 days overdue. Please arrange payment by [date] to avoid a late fee."*

Day 44 (+14 days late)

Reference your late fee clause: *"As per our payment terms, a 1.5% monthly late fee has been applied. The new balance is [amount]."*

Day 60+

Consider a formal demand letter or small claims court for persistent non-payment.

Prevention tip: Get a 50% deposit upfront for new clients and project work. This filter alone eliminates most payment problems.
