A professional consulting invoice should include your business name and contact info, client details, invoice number, date, itemized services with rates, total amount, payment terms, and due date. ZapInvoice includes all of these fields.
It depends on your consulting model. Hourly works well for ongoing advisory work. Project-based billing is better for defined deliverables. ZapInvoice supports both — add line items however you prefer.
