Frequently asked questions

What does net 30 mean?

Net 30 means the full payment is due 30 days after the invoice date. Due on receipt means payment is due right away.

Does the calculator skip weekends or holidays?

No. It counts calendar days. Some businesses move a due date that falls on a weekend or holiday to the next business day, so check your own policy.
