Frequently Asked Questions

Where do I add payment terms?
The payment terms section at the bottom includes fields for due date, accepted payment methods, and late fee policy.
Can I describe the scope of work?
Yes. The description field for each service line has room for detailed notes about the work performed.
Does it handle multiple billing periods?
Each invoice covers one billing period. Create a new invoice for each period and reference the dates in the billing period field.
