Invoicing with Billit via SAT

    Before you can sign an invoice, you need to fill in the correct information for both your company and your customer.

    • Go to 'My company' in the top left corner and the 'Company' tab
    • Click the '+' sign next to 'VAT or CBE NO' and select 'TIN'
    • Fill in your TIN number

    Send and sign an e-invoice

    After creating an invoice, you will see a "Sign E-invoice" button at the bottom. Click it and you will get a pop-up asking for your confirmation. Choose 'Confirm' to sign your e-invoice.

    A new section with the signature data and QR code will  now appear at the bottom.

    To send you invoice, click the 'Send' button at the bottom and choose on of the delivery methods.

    If you attempt to send an unsigned invoice, it will be signed first before being sent.

    Please note: Once your invoice is signed, you cannot edit it anymore. Make sure your invoice is final before you click 'Sign E-invoice'.
