Your customer signs wherever they happen to be
You send a quote, cost estimate or order confirmation as a link, and your customer signs with a finger or the mouse — no account, no printer, no scanner. As soon as they have signed, an email lets you know.

How it looks
One link, one name, one signature
Your customer opens the link without an account and signs on their phone, in the language of the document. As soon as they have signed, you get an email, and they download their copy.
In detail — One link, one name, one signature
Before that they see the document, date, subject and total amount, and can open the document as a PDF; they enter their name, sign with a finger or the mouse and press “Accept and send”. The email goes to the person who created the link, as long as they may see the document in Zirko, and the signed copy then sits with the document. The copy for your customer is ready to download for fifteen minutes, with the log sheet; after that they get it from you. You send the link from Zirko: in the “Send by email” dialog, “Insert signature link” puts it into your message, and a link that has expired, been invalidated or been mangled while editing does not go out.
What else it takes off your hands
A log that says something in a dispute
In a dispute, you can show who accepted which document and when — and that it was the same one you sent. The acceptance log records name, signature, time, IP address, device and the checksum of the document.
In detail — A log that says something in a dispute
A transaction reference is added; the sheet is the last page of the signed PDF and is in the language of the document — your customer gets the same file as their copy.
A link that does not last for ever
The link is valid for thirty days at most, and it can be signed only once. If it went to the wrong address, you invalidate it; if you create a new one, the old one stops working at once.
In detail — A link that does not last for ever
Anyone who opens a dead link reads that it is no longer valid, and once it has been signed there is no new one. It cannot be guessed, and the database holds only its fingerprint: anyone reading the database cannot build a valid link from it. That is why Zirko shows it only once, when it is created.
A drawn signature, not a qualified signature
The signature via the link is a hand-drawn signature with a log, not a qualified electronic signature. Where the law requires a contract to be signed on paper, it does not replace that. There is no link for invoices: they wait for a payment, not for an acceptance.

Frequently asked questions
How do I get a quote signed electronically?
With a link: you create it on the issued document and send it from Zirko by email — in the “Send by email” dialog, “Insert signature link” puts it into your message — or share it. Your customer opens it, checks the document, enters their name and signs with a finger or the mouse. They do not need an account for it.
Which documents can my customer sign this way?
Quotes, cost estimates and order confirmations. Not invoices — they wait for a payment, not for an acceptance.
Is a signature by link legally valid?
It is a drawn signature with a log: name, time, IP address, device and checksum of the document. It is not a qualified electronic signature; where the law requires a signature on paper, it does not replace one.
How long is the link valid?
Thirty days at most from when it is created, and it can be signed only once. Until then anyone who has the link can open it — so send it only to the person who is to sign, and invalidate it if it went to the wrong one. Once it has expired, the page tells your customer it is no longer valid, and you create a new one.
Does Zirko remind me before a link expires?
Yes, with Zirko Automation: the automation for an expiring signature link lets your business know in good time, as long as nothing has been signed yet. Zirko Automation is an add-on; what it costs is on the pricing page.
Will I find out when my customer has signed?
Yes, by email: whoever created the link gets one with the document, the time and the customer's name, as long as they may see the document in Zirko. The signature stays on the document for good, with the signed PDF including the acceptance log. Whether the customer has merely opened the link is not something Zirko tracks.
Does my customer get a copy of the signed document?
Yes. Right after signing, they download the signed PDF with the log sheet, for fifteen minutes. After that they get the copy from you — you download the same file from the document.
In which language does my customer see the page?
In the language of the document. If you issue a quote in another language, the signing page is in that language too, and so is the acceptance log. If someone opens a link that is no longer valid, the notice is in the language of their browser.
