Mobile Notary Invoicing App (2026)
A solo mobile notary or loan signing agent needs to get paid at the signing and keep the seal fee separate from the uncapped travel, print, and scan charges — card or tap-to-pay on the phone, a flat package fee for loan signings, and a trip fee when a signing falls through. ShowTheReceipts ($15/mo) takes a card or payment link on site with no hardware, saves your signing and travel lines, and tracks the fee on every appointment.
How we picked
Entry-plan prices as published in 2026, taken from each vendor's own pricing page or a recent third-party summary. Judged on the solo mobile notary and loan signing agent's workflow — card at the table, a capped seal fee kept separate from uncapped travel and print charges, flat signing packages, and trip fees on fall-throughs — not on multi-notary signing-service dispatch or title-company platforms built for a staffed office.

Get paid before you leave the table
The friction in notary work is the gap between the seal and the money — a signing company on net-30, or a personal client who says they’ll pay later. Cash isn’t always there, and neither is the check.
Take the card at the signing, and the job’s actually done when it’s done.

What a mobile notary invoice needs
- Notarization — per-seal cap × number of seals
- Travel fee — flat or by distance, its own line
- Print / scan-backs — per page or flat, itemized
- After-hours — surcharge when it applies
- Trip fee — for signings that fall through
The two things that matter
Everything comes down to getting paid on the spot and keeping the capped seal fee separate from the uncapped travel and prep. A tool that does those two well beats one with a hundred features built for a staffed signing service.
Frequently asked questions
How do I take card payments with no hardware?
Tap-to-pay on your phone for a card or Apple Pay at the signing, or send a payment link the client taps on theirs. Both settle before you leave, instead of waiting on a signing company's net-30 or chasing a personal client afterward.
Can it keep the travel fee separate from the seal fee?
It should — on separate invoice lines. Only the notarization is capped by your state; the travel, print, and scan-backs are not, so itemizing them keeps your regulated fee clean while you still earn for the trip and the prep.
Do I need notary-specific software as a solo notary?
Not the signing-service dispatch kind. A solo notary or LSA needs booking, a card at the table, travel fees kept separate from the seal, flat signing packages, and a trip fee on fall-throughs — order routing and title integrations are built for a staffed office you're not running.
Can I charge a trip fee when a signing falls through?
Yes — bill it as its own line. If you printed the package and drove out and the signer backs out, you've spent the time and fuel either way, and a stated trip fee turns a wasted trip into a covered one.
