Frequently Asked Questions
What does Net 30 mean?
Net 30 means payment is due 30 calendar days after the invoice issue date unless you and the client have agreed to something else.
Should I move a due date that lands on a weekend?
Many freelancers move weekend due dates to the next business day for clarity. This tool lets you choose that behavior without assuming local holiday rules.
Does this tool account for local holidays?
No. Phase 1 uses calendar days and an optional weekend shift only, so it stays globally neutral.
