Is a free invoice legally binding?

An invoice created with any tool is legally binding if it contains the required information. In most jurisdictions, no specific format is required — just clear identification of parties, services, amounts, and payment terms. A PDF or printed invoice is equally valid.

How do I number invoices?

Use a sequential numbering system: INV-001, INV-002, or by year INV-2024-001. Sequential numbering is important for accounting and tax records. Never reuse invoice numbers or skip numbers — tax authorities use invoice numbering to detect gaps.

What payment terms should I use?

Common terms: Net 30 (payment due in 30 days), Net 15, Due on receipt (immediate). For new clients, consider Net 15 or a 50% deposit. Include late payment interest (e.g. 1.5%/month) in your terms to encourage prompt payment.

Do freelancers need to add VAT/GST?

Only if you are VAT/GST registered in your country, which typically happens above a revenue threshold. UK VAT threshold: £90,000/year. Australian GST: AUD 75,000/year. US has no federal sales tax for services. Check your local requirements.
