A mobile notary business earns its money twice: once from the public for general notary work, and once from signing services and title companies for loan packages. Each side pays differently, so the app you use has to handle a card at the table and an invoice with net terms.
How to get paid as a signing agent comes down to paperwork you send before you leave: a loan signing agent invoice with the fee breakdown and confirmation attached and a clear due date. Signing service payments still take time, but a bill with reminders is harder to lose than an emailed spreadsheet. When a company pays by ACH, the money moves without anyone printing or mailing a check.
For general notary clients, collect the mobile notary travel fee when you confirm and take the rest at the signing. Your state sets the notarial fee, while travel and convenience fees are usually yours to set and should be agreed in writing first. A signer who knows the trip fee up front rarely argues about it at the door.
KadePay handles mobile notary booking requests, payments and policy forms. It is not an electronic notarization platform or a notary journal, so keep your journal and any remote online notarization tools as your commission requires.
