What every freelance invoice needs
Your business details
Legal business name, address, email, phone number, and tax ID (EIN, BTW, USt-IdNr). This identifies you as the seller and is required for tax compliance.
Client details
Client company name, billing address, and contact person. Ensure these match the entity that will process the payment.
Invoice number
A unique, sequential identifier. Use a consistent format like 2026-001, 2026-002. Required for tax records and prevents duplicate payments.
Issue and due dates
The date the invoice was created and when payment is expected. Common terms: Net 14 (due in 14 days) or Net 30 (due in 30 days).
Line items with descriptions
Each service or deliverable as a separate line: description, quantity or hours, unit rate, and line total. Specific descriptions reduce client questions.
Subtotal, tax, and total
Subtotal before tax, applicable tax amount and rate (VAT, sales tax), and the final total due. EU invoices must show VAT separately.
Payment instructions
Bank name, IBAN or routing + account numbers, and accepted payment methods. The easier you make it to pay, the faster you get paid.
Late payment terms
State what happens if payment is late: penalty percentage, interest rate, or suspension of work. Setting expectations upfront reduces friction.
Tips from experienced freelancers
Use sequential invoice numbers
Start with a format like YYYY-NNN (2026-001, 2026-002). Never reuse or skip numbers. Tax authorities expect unbroken sequences, and gaps raise flags during audits.
Set clear payment terms
Net 14 works best for smaller projects. Net 30 is standard for ongoing work. State the terms on every invoice — don't assume the client remembers from the contract.
Include your tax ID
EU clients need your VAT number for reverse charge. US clients may need your EIN for 1099 reporting. Including it proactively avoids back-and-forth at tax time.
Why generate with TAV
Log hours per project. At invoice time, TAV pulls all unbilled entries and builds the invoice automatically.
TAV detects your region and applies the correct tax rate. EU reverse charge, US sales tax — handled automatically.
Overdue invoices get automatic reminders at 3, 7, and 14 days. You never write the awkward follow-up email.
Invoice in EUR, USD, GBP, or any currency. Currency carries through to the PDF and your financial exports.
Every invoice is a clean, branded PDF with your logo and business details. TAV is invisible to your client.
TAV generates invoice numbers automatically using atomic database sequences. No gaps, no duplicates, audit-ready.
Common questions
What should a freelance invoice include?
Every freelance invoice needs your business details (name, address, tax ID), client details, a unique sequential invoice number, issue and due dates, itemised line items with descriptions and amounts, subtotal and tax breakdown, payment instructions (bank details or payment link), and late payment terms. EU invoices must also show VAT separately with the applicable rate.
Do I need an invoice number?
Yes. Invoice numbers are required for tax compliance in most jurisdictions. Use a sequential format like 2026-001, 2026-002 — never skip or reuse numbers. Tax authorities expect an unbroken sequence. TAV generates these automatically using atomic database sequences so there are no gaps or duplicates.
What payment terms should freelancers use?
Net 14 (payment due within 14 days) is common for project-based work. Net 30 is standard for ongoing retainers and larger clients. Some freelancers offer a 2-3% discount for early payment (Net 10). State the terms clearly on every invoice — both in the due date and in a payment terms section.
Should I charge VAT on my freelance invoice?
If you are VAT-registered in the EU, yes — you must charge and display VAT on invoices to domestic clients. For B2B sales to clients in other EU countries, the reverse charge mechanism applies: you show 0% VAT and note "Reverse charge applies." US freelancers generally do not charge federal VAT but may need to collect state sales tax depending on the service and state.
How do I invoice international clients?
Include your full legal business name and tax ID. Specify the currency clearly. For EU cross-border B2B invoices, use the VAT reverse charge mechanism and include both tax IDs. For US-to-EU invoicing, note that no VAT applies. State payment method (SWIFT/IBAN for international wire, or use a platform like TAV that handles SEPA, ACH, and card payments).
Can I create recurring invoices for retainer clients?
Yes. For retainer agreements with fixed monthly fees, you can set up recurring invoices that generate automatically each billing cycle. TAV lets you create invoices from tracked time or fixed amounts, and the automatic numbering and payment follow-up run on every invoice — whether one-off or recurring.
Stop formatting invoices by hand.
TAV generates invoices from your tracked work. Review, send, get paid.
