Email invoices to Booko

Prefer email over uploading? Booko can create separate email addresses for your administration: one for costs and one for revenue. Invoices you send there are queued for AI classification automatically.

Steps

1. Click Upload invoice.
2. At the bottom, expand Send invoices by email.
3. Under Costs Inbox or Revenue Inbox, click Create email address.
4. Click Copy address and save it in your address book.
5. Send your invoices to that address, or forward them from your mailbox.

Which inbox?

• Costs Inbox: for supplier bills, receipts and purchase invoices. Creates costs.
• Revenue Inbox: for sales-side invoices that should land in revenue. Creates revenue.

Good to know

• Each inbox shows Last email received with a date, so you can see whether your email arrived.
• Need a new address (for example because of spam)? Choose Regenerate address. The old address stops working immediately.

Still stuck?

• Seeing the status Domain pending or Domain not connected yet? Then inbound email doesn't work yet. Upload your invoices manually for now and ask for a colleague in the chat.
• Nothing shows up under Costs or Revenue and Last email received stays at Never? Check the address, then ask for a colleague in the chat.
