Notarize vs OneNotary pricing and what Proof and OneNotary cost a business each month

OneNotary is cheaper than Proof for almost every business pattern on list prices. A one-signer, one-document session costs about 33 USD on Proof Pro and 25 USD on OneNotary. With your own notary, Proof requires Pro+ at 199 USD a month plus 15 USD per in-house meeting, while OneNotary charges 10 USD per notarization plus a 25 USD monthly notary subscription. Proof's strengths are elsewhere: lender and title workflows, a large on-demand network and enterprise contracts.

If your team notarizes every week, the cheaper answer may be neither. A plan with sessions included turns a bill that moves with every signer into one fixed monthly figure.

Proof figures come from proof.com/pricing (checked October 2, 2026) and OneNotary figures from onenotary.com/pricing-new (checked October 5, 2026). Both vendors change prices, so confirm before you sign.

Two lines decide most bills. Proof's identity and signing fees add 8 USD to even the simplest session, and its 15 USD seal fee hits hard on document sets like a corporate resolution plus an affidavit plus a power of attorney. OneNotary's catch is storage: pay as you go keeps documents for only 7 days, so most companies end up on Business Professional anyway.

Each row is one month at list prices with network notaries, without volume discounts. The OneNotary column includes Business Professional at 65 USD a month, because a business usually needs its storage, team members and API.

At four simple sessions a month, OneNotary pay as you go at 100 USD is the cheapest option of all if seven-day storage is acceptable, and we would say so to any buyer. From around a dozen multi-signer sessions a month, both per-session models cost two to six times a flat plan. The Proof own-notary row includes its identity and signing fees on each in-house meeting.

Proof makes sense when you are a lender or title agency that needs its real estate price list, its integrations with closing systems or an enterprise contract with custom pricing. Its network is large and available around the clock, and its mortgage package pricing (150 USD for a purchase or refinance package with a network notary, 90 USD with your own notary) is built for closings rather than one-off documents.

OneNotary makes sense for HR and operations teams. Business Professional bundles unlimited team members, templates, branding, a REST API and remote Form I-9 with E-Verify integration for 65 USD a month, which is hard to match for onboarding paperwork at low volume.

A flat plan makes sense when the volume is steady. Commercial real estate teams are a good example: lease amendments, estoppel certificates and guaranties often need notarizing in the same week the terms are pulled into a summary with lease abstraction software, and paying per seal on every one of those documents adds up quickly.

Many title agencies, law firms and banks already employ commissioned remote notaries. On Proof, bringing them onto the platform requires Pro+ at 199 USD a month, and each in-house meeting then costs 15 USD plus identity and signing fees. On OneNotary, each connected notary pays a 25 USD monthly subscription and each notarization costs 10 USD, with 4 USD per extra seal or signer.

For one staff notary running 30 simple sessions a month, that is about 889 USD on Proof against 325 USD on OneNotary, or 390 USD with Business Professional. ENotary Business includes 2 own-notary seats at 299 USD a month, or 149 USD billed yearly, and sessions your notaries run do not use the 12 network sessions in the allowance.

Proof and OneNotary are two of several platforms with business pricing. BlueNotary is the low-cost pick for teams with their own notary, at 47 USD per notary seat a month. NotaryLive bundles seals and signatures into a 25 USD session. Our Notarize alternatives page compares all of them in one table, and the BlueNotary alternative page puts BlueNotary, Proof and OneNotary side by side. For a deeper look at one vendor, read Notarize pricing or OneNotary pricing.

Yes, on list prices OneNotary is cheaper for almost every business session. Both charge 25 USD for a basic notarization, but Proof adds 4 USD per signer for identity and 4 USD for signing, plus 15 USD per extra seal against OneNotary's 10 USD. A two-signer, three-document session is about 77 USD on Proof and 55 USD on OneNotary.

Is Notarize the same as Proof?

Yes. Notarize renamed itself Proof in 2023, and its business plans are now sold as Proof Pro, Pro+ and enterprise tiers at proof.com. People still search for Notarize, and the consumer service is still widely known by that name, but the pricing and the platform are Proof's.

How much does OneNotary Business Professional cost?

OneNotary Business Professional costs 65 USD a month billed monthly, or 49 USD a month billed annually. It adds unlimited team members and storage, templates, branding, a REST API and remote I-9 tools. Notarizations are still charged on top, starting at 25 USD each.

Does Proof charge per signer?

Yes. Proof charges 4 USD per signer for identity verification and 10 USD for each additional signer beyond the first, on top of the 25 USD meeting fee and a 4 USD signing fee. Additional seals cost 15 USD each, so multi-signer business sessions cost well above the headline price.

What is a cheaper alternative to Notarize and OneNotary for a business?

For a team running about 12 or more multi-signer sessions a month, a plan with sessions included usually costs less than either. ENotary Business is 299 USD a month, or 149 USD billed yearly, with 12 network sessions of up to 4 signers and 10 documents each plus 2 own-notary seats.

Take last month's notarizations and write down three numbers: sessions, average signers per session and average seals per session. Price that month on Proof, on OneNotary with Business Professional, and on the online notary cost page. If the per-session bills land within a few dollars of a flat plan, keep the flexibility. If they land at two or three times the plan, the decision is already made.
