Yes, this is a digital signature system

Digital signatures for business, from the document to the closed deal

Everything you expect from a digital signature system is here: upload a PDF, place the fields, send it, get it signed. And then okdoc keeps going, because a signature is worth more when you know what happened before it.

The basics, done properly

Everything you expect from a digital signature system

No asterisks and no paid add-ons for the basics. This is the part you came for, and it works on every plan.

Legally binding e-signature

Every signature carries a full audit trail: who signed, when, and from where.

Sealed, tamper-evident PDF

The signed file gets a SHA-256 fingerprint and a certificate of completion, so any later edit is visible.

Upload any PDF, AI places the fields

Drop in a contract you already have and the signature, name and date fields are placed for you. You can also write a document from a one-sentence prompt.

Multiple signers, with roles

Sequential or parallel, whichever the deal needs. Each signer gets their own fields.

OTP identity verification

A one-time code confirms the signer is who they say they are before the document opens.

WhatsApp, email, or a direct link

Send where your client actually answers. A reusable template link lets anyone sign the same document on demand, and each signature counts as one deal against your monthly quota.

Also included: reusable templates, AI document generation from a one-sentence prompt, an offer countdown timer, 5 interface languages with full RTL, and an AI translation of the document shown to the signer next to the original.

Track

But signing is not the end, it is the middle

The moment you hit send, a normal signature tool goes quiet. okdoc starts measuring. You see whether the client opened the document, how long they stayed, which page held them and where they hesitated, so you know who to call today.

Ships on the free plan

Opens, and dwell time per open

Three short opens and one long one are two very different deals. You see both numbers, not just a read receipt.

Time on each page and scroll depth

If they stopped on the pricing page and never reached the terms, that tells you exactly what the next conversation is about.

Click heatmap

The spots the signer tapped and re-read, painted straight onto the document.

Deal heat status

All that behaviour resolves into one word you can sort your list by, so the follow-up order picks itself.

A live WhatsApp alert

The moment the client opens the document, your phone buzzes. That is the window where a call actually lands.

Measured first-party. No third-party trackers.

Sign and pay, in the same click

The gap between a signature and the money arriving is where deals go cold. okdoc closes it on the signing page itself.

Charged at the moment of signature

The signer's card is charged on the signing page, as part of signing. No second link, no chasing a transfer.

Your own payment account

You connect the provider you already work with, and the money goes straight to you. Seven providers are supported.

Invoice and receipt, automatically

An invoice and receipt are issued and emailed the moment the payment goes through.

Revenue dashboard

Signed, paid and outstanding in one view, so the pipeline and the bank account tell the same story.

Frequently asked questions

Is the signature legally binding?

Yes. Every signature is a legally binding e-signature with a full audit trail, and the signed file is sealed and tamper-evident with a SHA-256 fingerprint and a certificate of completion.

Can I upload a PDF I already have?

Yes. Upload any PDF and AI places the signature, name and date fields for you. You can also have AI write a quote, proposal or contract from a one-sentence prompt, or start from a saved template.

What counts as a deal?

A deal is a document you actually sent. Drafts never count. The free plan includes 5 deals a month and the counter resets on the 1st. A signature created from a reusable template link also counts as one deal.

What exactly do you measure after I send?

The number of opens, the dwell time of each open, the time spent on each page, scroll depth, a click heatmap and a deal heat status. You also get a live WhatsApp alert the moment the client opens the document. It is all measured first-party, with no third-party trackers, and it is not gated on any plan.

How does payment on the signing page work?

You connect your own payment account from seven supported providers: Sumit, Cardcom, Grow, PayPal, PayPlus, Stripe and Tranzila. The signer's card is charged at the moment of signature and an invoice and receipt are issued and emailed automatically. okdoc never touches the funds and takes no commission on your payments, while your payment provider charges its own fees.

Can several people sign the same document?

Yes. You define several signers with roles and choose whether they sign one after another or all at once. Each signer can be verified with a one-time code, and the document can be shown to them translated by AI alongside the original.

Start with the signature. Keep the whole deal.

5 deals a month on the free plan, no credit card, and the tracking is included from the first document.
