Free Invoice Generator for UK and Australia — Simple, No Account

UK freelancers and Australian sole traders have slightly different invoicing requirements than US-based businesses — VAT registration, ABN inclusion, GST rates — but the core invoice format is the same. WildandFree's free invoice generator creates the right structure: your details, client details, line items, tax calculation, and a clean PDF download. Add your VAT number or ABN in the notes field where required. No account, no UK or Australian-specific sign-up, no subscription.

UK Invoice Requirements for Freelancers and Sole Traders

In the UK, a valid invoice for VAT-registered businesses (and for record-keeping by any business) must include:

• A unique invoice number (sequential)
• The date of invoice
• Your business name and address
• The client's name and address
• A description of the goods or services supplied
• The amount charged, excluding VAT
• The VAT rate applied (if VAT registered)
• The total VAT charged
• The total amount including VAT
• Your VAT registration number (if VAT registered)

If you are below the VAT registration threshold (currently £90,000 annual turnover), you do not need to charge VAT and do not need a VAT number. Your invoice simply shows the net price with no VAT line.

How to set this up in the tool: Enter 0% tax rate if you're not VAT registered. Enter your VAT rate (standard 20% for most services) if you are registered. Add your VAT registration number in the notes field — "VAT Reg. No: [your number]" is the standard format.

Australian Invoice Requirements — ABN and GST

In Australia, invoicing requirements depend on whether you are GST-registered:

If you have an ABN but are not GST-registered (under A$75,000 annual turnover):

• Include your ABN on all invoices
• Do not charge GST — leave the tax rate at 0%
• The invoice is technically a "tax invoice without GST" or simply a "receipt"

If you are GST-registered (over A$75,000 annual turnover, or voluntary registration):

• Must issue a "tax invoice" for any supply over A$82.50
• Must include your ABN and the words "Tax Invoice" prominently
• Apply 10% GST to taxable supplies
• Show price excluding GST, GST amount, and total including GST as separate line items

In the WildandFree tool: Enter your ABN in the invoice notes (required for all invoices). Set the tax rate to 10% if GST-registered. Add "Tax Invoice" to your invoice notes or business name field to make the designation clear. The tax calculation handles the rest.

Canada and South Africa — Quick Reference

Two other common English-speaking markets with specific invoice requirements:

Canada: If you're registered for GST/HST (mandatory over C$30,000/year, optional below), you must include your GST/HST registration number on all invoices and show the tax amount separately. The federal GST rate is 5%. HST rates vary by province (13–15%). Enter the applicable combined rate in the tax field and note your registration number in the invoice notes.

South Africa: VAT-registered businesses must include their VAT registration number and apply 15% VAT to most supplies. The threshold for mandatory registration is R1 million annual turnover. As in the UK and Australia, add your VAT number in the notes field and set the tax rate to 15%.

In all cases, the invoice generator's tax calculation field handles the math. The notes field is where you place any registration numbers, statutory declarations, or other country-specific language your clients or tax authority requires.

Practical Invoicing Tips for UK and Australian Freelancers

UK-specific:

• Use "Payment terms: 30 days" as a standard — UK law supports this as a default for commercial transactions under the Late Payment of Commercial Debts Act
• Bank transfer (BACS) is the dominant payment method in the UK — include your sort code and account number in the notes field
• If clients are slow to pay, statutory interest of 8% above base rate applies to late B2B payments — worth knowing as leverage even if you rarely exercise it

Australia-specific:

• Clients paying you more than A$75 per year without your ABN are legally required to withhold 47% from your payment — always include your ABN
• Bank transfer (BSB and account number) is standard — include both in your notes
• For sole traders working with government clients, you may be required to provide a PAYG withholding variation — check with an accountant if this applies

Both markets have strong protections for self-employed workers and straightforward invoice requirements. The biggest practical task is registering for an ABN (Australia, free and instant via ATO website) or getting a VAT number if applicable (UK, via HMRC).

Frequently Asked Questions

Can UK freelancers invoice without a VAT number?

Yes. Below the £90,000 VAT registration threshold, you do not register for VAT and do not charge it. Your invoices simply show the net price. You only need a VAT number if your turnover exceeds the threshold or you choose to register voluntarily.

Is an ABN required to invoice in Australia?

Yes. Without an ABN on your invoice, clients are legally required to withhold 47% (the top marginal tax rate) from your payment. Getting an ABN is free and takes about 10 minutes through the Australian Business Register at abr.gov.au.

How do I show GST separately on an Australian invoice?

In the WildandFree tool, enter 10% in the tax rate field. The tool shows the subtotal, tax amount, and total including GST as separate rows on the invoice preview. Add "Tax Invoice" and your ABN in the notes field to meet the tax invoice requirements.

What currency does the invoice generator use?

The invoice generator does not enforce a currency symbol — you can type the amounts in any currency. Add the currency explicitly in your line item descriptions or notes (e.g., "All amounts in GBP" or "All amounts in AUD") to make it clear on the PDF.
