Everything UK freelancers need to invoice professionally — and actually get paid

Branded, client-ready PDFs generated instantly. Looks polished from day one.

Set your own prefix and starting number — e.g. INV-001 or 2025-001.

Add a project or engagement name to make invoices easy to identify.

Standard 20%, reduced 5%, and zero-rated VAT — calculated automatically per line item.

Your VAT registration number appears on every invoice — required by HMRC for VAT-registered businesses.

Invoice in GBP, EUR, USD, CAD, or AUD. Ideal for international clients.

Add your company logo so invoices match your brand.

Personalise the invoice colour to match your brand identity.

Include your standard T&Cs or late-payment clause on every invoice.

Add a free-text note — useful for bank details, project context, or a thank-you.

Set a specific due date. Invoa uses it to detect overdue invoices automatically.

Store a separate billing contact address per client for accurate invoice delivery.

Select a client, enter how many hours or days you worked, and hit save. The line item is added to their invoice instantly.

Set a default rate (e.g. £500/day or £75/hour) on each client. Quick Add pre-fills it every time so you never have to type it again.

Quick Add automatically attaches the line item to the client's latest draft invoice — or creates a new one if none exists.

Prefer a different invoice? Pick from the dropdown of open drafts for that client before saving.

The invoice subtotal and total are recalculated automatically each time a Quick Add line item is added.

Save a client once and select them when creating future invoices — no re-entering addresses.

Store full billing details including the legal entity name required on UK invoices.

See every invoice sent to a client — amounts, dates, and current status — in one place.

Every invoice moves through Draft → Sent → Paid → Overdue. See the full picture at a glance.

Invoa automatically marks invoices as overdue once the due date passes — no manual checking needed.

Received payment outside the system? Mark invoices as paid with one click.

Connect your UK bank account via Open Banking (Beta). Invoa reconciles incoming payments against open invoices automatically.

Reminder emails sent automatically to clients on your configured schedule — no manual action required.

Choose when reminders are sent: e.g. 7 days before due, 1 day before, on the due date, and 7 days after.

Every reminder email includes the original invoice as a PDF attachment so clients can pay immediately.

Reminders fire without you needing to log in — Invoa handles it in the background.

Hit send and the invoice is delivered to your client's inbox — no need to download and attach manually.

The invoice PDF is generated and attached to every outgoing email without any manual steps.

A clean, branded email wraps your invoice — making a good impression with every send.

Your company name appears in the email so clients know exactly who it is from.

Invoices include all fields required by HMRC: supplier name, address, VAT number, tax point date, VAT amounts, and totals.

Display your Companies House number on invoices — required for UK limited companies.

Add international bank details for clients paying from overseas.

UK bank transfer details displayed prominently on every invoice for domestic payments.
