What are payment terms?
A payment term of 30 days means the customer has 30 calendar days to pay you after you invoice them. This will usually be from the date on your invoice.
Even if you don't verbally agree on a payment date with customers, they should pay you within 30 days of this date if that's what it says on the invoice.
