How to Create and Send Your First Invoice

Sending a professional invoice is one of the most important things you can do to get paid on time. Here's how.

How to Add Line Items, Taxes, and Discounts to an Invoice

AstaBill lets you break down your charges by item, apply VAT or other taxes, and offer discounts — all in one place.

How to Set a Due Date and Payment Terms

Setting a clear due date tells your customer exactly when to pay and helps AstaBill flag overdue invoices automatically.

How to Share an Invoice Link with a Customer

AstaBill gives each invoice a unique public link you can send via WhatsApp, SMS, or any messaging app.

How to Mark an Invoice as Paid Manually

If a customer pays by cash, bank transfer, or mobile money, you'll need to mark the invoice as paid yourself.

How to Create a Credit Note for a Returned Order

If a customer returns goods or you need to cancel part of a paid invoice, a credit note is the correct way to handle it.

How to Duplicate or Copy an Existing Invoice

Invoice duplication is coming soon — in the meantime you can quickly recreate an invoice from scratch.

How to Void or Cancel an Invoice

If you sent an invoice by mistake or a deal fell through, you can void the invoice. It stays in your records but is marked as cancelled.
