Create at /invoices/create. Select or add a customer, set invoice number, currency and dates, add items and totals, then save. Invoice numbers can be customized during creation and editing.
Review the preview and select Approve invoice before sending. Send by email, obtain a share link, or mark an externally delivered invoice as sent. Mark-as-sent counts as issuing. Free users can send three unique invoices monthly; the fourth requires Pro. Group sending is all-or-nothing when allowance is insufficient.
