What information should I include on an invoice?
A professional invoice should include: your company name and address, the client's name and address, a unique invoice number, the invoice date and due date, payment terms, an itemized list of services or products with quantities and prices, subtotal, any applicable tax, and the total amount due. You can also add notes or payment instructions.
How are invoice numbers generated?
Invoice numbers are auto-generated using the format INV-YYMMDD-XXXX, where YYMMDD is the current date and XXXX is a random 4-digit number. You can edit the invoice number to use your own numbering system. Consistent invoice numbering helps with bookkeeping and tax records.
