Sent in a few clicks
Choose Send and the invoice goes to your customer as a PDF, from your brand's name. Replies go to the brand's email, and you can send it again as a reminder.
Quotes and estimates
Offer a price until a date. When the customer agrees, turn the quote into an order or an invoice, filled in for you.
Customer accounts
Everything a customer buys on account goes on one running balance, with a statement of each invoice and payment.
Payments, whole or in part
Take a payment against what a customer owes. It pays their oldest invoices first, and each shows unpaid, partly paid or paid.
Who owes what
See everyone who owes you, most first, who's overdue, and who has a credit.
Your details on every invoice
Your business name and address, your GST/HST and other tax numbers, and how to pay, such as by e-transfer.
Questions
- Does an invoice count as a sale?
- Yes. An invoice is a sale your customer pays later, so it counts in your sales, and its items come out of stock.
- Which tax numbers do my invoices need to show?
- IAPZ prints every tax registration number you enter. Which ones your invoices must show, and when, is a question for your accountant.
- Can I sell on account at the counter too?
- Yes. At the point of sale, choose the customer and tap Pay later. The sale becomes an invoice on their account.
