  1. Once signed in, go to Companies → New company.
  2. Fill in business name, country, currency, tax ID (NIF/CIF for Spain), and upload a logo.
  3. Adjust logo size and position — this is exactly how it renders on your PDF invoices.
  4. Choose an invoice prefix and starting number for each series (invoice / proforma / albarán / receipt).

3. Add customers

  1. Go to Customers → New customer.
  2. For Spanish clients use the AI Lookup box: type a company name or NIF and click Search to prefill the form.

6. Send an invoice by email

7. Record and correct payments

  1. On the invoice detail page click 'Record payment'.
  2. Enter amount, method, and optionally email a receipt to the client.
  3. Made a mistake? Each payment row has Edit and Delete buttons that recompute invoice balance and status.

8. Automated reminders

  1. In Customers, toggle 'Auto-send AI payment reminders' for the clients that opt in.
  2. Every day at 08:00 UTC the scheduler drafts localized reminders for overdue invoices and sends them.
  3. You can review sent reminders in the invoice's Email delivery panel.

9. AI Automations page

  1. Open AI in the sidebar.
  2. Use 'Receipt OCR' to bulk-scan receipts, review each extracted field, and save the draft invoice.

10. Manage plan and limits

  1. The free plan allows 15 issued invoices per month per company.
  2. When you hit the cap, issuing new invoices is blocked — drafts still work.
