Getting a contract signed still costs more time than negotiating it. You print the document, sign it, scan it back and email it, then wait for the other side to do the same. When a signature has to be notarized, add a trip and a fee. When the other party sits three time zones away, add days.
Faced with all that work, plenty of companies skip the paperwork and close on a handshake or a message thread. The bill for that arrives later, because without a signed agreement, collecting from a client who does not pay starts with proving the agreement existed at all.
Signater takes the paper out of the process. You upload the document, enter the name and email of each person who has to sign, and the platform sends every one of them a link. They sign from a phone or a laptop, wherever they are, in a few minutes. Nobody prints, nobody mails, nobody drives anywhere.
Every new account starts free, with three documents a month and no credit card. For real workload, the paid plans are three: Starter, Business and Enterprise.
What you get when someone signs
Once the last person signs, everyone receives the same signed PDF. Three things travel inside it that paper never carried.
The audit trail is the document's history, close to package tracking: who opened it, who signed, on what date, at what time, from which internet address and from which location. Signater records every step. That history is what you produce if someone later claims they never signed.
The timestamp writes the exact date and time of the signature into the file itself, from a trusted time source. It proves when the signature happened without leaning on the clock of the computer that signed.
Legal validity comes from the U.S. ESIGN Act and UETA, which give an electronic signature the same weight as ink on paper, and from eIDAS, which extends that recognition across the European Union. Our legal validity page covers how each one applies.
The practical effect shows up when a deal goes wrong. A signed contract backed by an audit trail moves the argument away from whether an agreement existed and onto whether its terms were met.
How Signater charges
Signater charges by envelope. An envelope works like a paper one: you put as many documents inside as you need and as many people as you need to sign them, and the whole thing travels together under a single track.
A lease with two attachments, signed by the landlord, the tenant and two witnesses, uses one envelope. Not four, not three. One.
At checkout you pick two things: the plan, which sets the features, and how many envelopes you want per month. Each plan comes in more than one size, so you can have an advanced feature at a small volume.
Team size does not move the price. All three paid plans come with unlimited users: you add the whole office, each person signs in with their own login, and the monthly bill stays where it is.
What every paid plan includes
- Unlimited users, with a record of who did what inside the account.
- Legally binding signatures, a timestamp and a full audit trail.
- Password, email code and selfie verification. You decide what each person has to provide.
- Signing with the signer's own digital certificate. The signature is generated with their private key, which ties the document to them.
- A choice of signing country, for contracts governed outside your own.
- Document templates. Save the contract you send over and over with its blanks in place, like a form, then fill in the name and the amount.
- Automatic reminders that chase whoever has not signed yet, so you do not have to.
- Scheduling for the date a document goes out and the date it expires.
- Vaults, which are folders with a lock: only the people you authorize can open them.
- Search, reports and real-time alerts as people open and sign.
The three paid plans
Starter, from $39 per month
Starter costs $39, $99 or $149 per month, for 30, 100 or unlimited envelopes, and it delivers everything listed above. Each envelope takes up to 20 signers, up to 20 documents inside, and files up to 25 MB.
This is the plan for companies signing with people they already know: existing clients, employees, suppliers, partners. Service agreements, sales proposals, internal policies.
Business, from $79 per month
Business costs $79, $149 or $249 per month, for 30, 100 or 200 envelopes. Envelopes get bigger: up to 50 signers, up to 50 documents and files up to 50 MB.
It adds two fronts to Starter. The first one proves the person is who they claim to be:
- Selfie with liveness detection. The signer shows their face to the camera and the platform confirms a live person is there, rather than a printed photo or a recorded video. Signater tests this against the ISO/IEC 30107-3 presentation-attack standard.
- Identity document capture. The signer photographs an ID card, a driver's license or a passport with their own phone.
- Face match. The platform compares the face in the selfie against the photo on the document and answers whether they belong to the same person.
- SMS codes. The signer receives a number on their phone and types it in to sign. It comes with the plan, at no charge per message sent.
- Signatures that last. The PDF carries the proof that the signature was valid on the day it was made, and stays verifiable ten years from now, after the certificate behind it has expired.
The second front wires Signater into the systems your company already runs:
- API. A channel two programs use to talk to each other on their own. If you run a CRM or an ERP, meaning the system that holds your customers and your sales, the contract goes out from inside it and nobody has to open Signater.
- Webhooks. Signater tells your system the second someone signs, so nobody sits there checking.
- Testing environment. A separate copy of the platform where your developer can break things without touching a real document.
- Questions at signing time and a redirect that sends the signer to a page of yours the moment they finish.
Business also lets you require two-factor authentication from the whole team, the extra code your bank texts you when you log in. Chat support moves up to the special tier.
This is the plan for companies signing with strangers or with many people at once: real estate, lending, clinics, HR teams onboarding in batches. And for anyone who wants contracts going out from inside their own software.
Enterprise, $499 per month
Enterprise costs $499 per month with 200 envelopes, and it removes the size limits: as many signers per envelope as you want, as many documents, and files up to 100 MB.
It carries everything in Business, and adds:
- The platform under your brand. Your clients sign at an address of yours, something like signing.yourcompany.com, with your logo and your colors. The word Signater appears nowhere.
- Emails from your own domain. Signing notices reach people in your company's name.
- Digital seal with your own certificate. The signed PDF names your company as the party that sealed it.
- Single sign-on. Your team signs in with the same credentials they use everywhere else, and anyone who leaves the company loses Signater access in the same move.
- Accounts for your clients. You create and manage separate accounts, pay a wholesale price for them, and bill your client however you like.
- Priority chat support.
This is the plan for firms reselling signing as a service of their own, such as accounting practices and software houses, and for companies that need access control in one place.

On the annual plan, the whole year lands at once
The 40% discount is the first advantage of paying yearly. The second one is delivery. Signater puts every envelope for the year into your account on day one, in a single balance that lasts twelve months. A Business 200 annual account holds 2,400 envelopes in January, and no month rollover touches that number.
This weighs a lot for seasonal work. An accounting firm sends 40 documents in July and 400 in March, when annual filings close. Both volumes come out of the same balance, so the firm sizes its plan by the twelve-month total and ignores the peak month. The same goes for schools during enrollment, real estate in high season and insurance brokers at renewal.
Most platforms on the market release the balance month by month even while charging for the year up front, and whatever a slow month leaves behind never reaches the next one.
Frequently asked questions
Does Signater charge per user?
No. All three paid plans come with unlimited users. You pay for the account and for the envelope volume, and the size of your team stays out of the invoice.
What if I need more envelopes than my plan includes?
Paid plans give you two ways out. Additional envelopes cost $1 each, ride along with the plan and renew on every billing cycle. Standalone envelopes cost $2 each and never expire. The platform spends the plan's envelopes first and the standalone ones afterwards, which keeps the ones without a deadline intact. Starter Unlimited sits outside both, since its volume already has no ceiling.
Can I change the envelope count later?
Yes. You adjust the number of additional envelopes whenever you want, and the change applies from the next billing cycle. Moving to a more expensive plan for volume alone is never necessary.
What payment methods do you accept?
All plans accept credit card, on both monthly and annual billing.
How does cancellation work?
You cancel from the dashboard at any time, with no fee. The plan stays active until the end of the period you already paid for. After that the account returns to the free plan, and all of your documents stay where they are.
Where to start
Pick the plan by what your operation needs. If you sign with people you know, Starter covers it. If you need to prove who signed, or to wire Signater into your own system, go with Business. If you want the platform under your brand or plan to resell it to clients, Enterprise is the way. Then pick the size by your busiest month of the year.
The full table, feature by feature, sits on the pricing page. And you can try before you decide: create a free account and sign three documents a month, forever, with no credit card.
