SignTime's extensive feature lineup


Attach electronic contract related files in PDF or image format. Typically done for KYC (Know Your Customer) rules and other sorts of identity verification.


Tags improve the searchability of documents, and we support multiple tags per document. How many you ask? Hundreds, which is likely a larger number than you wish to use. We use tags internally for things like "Document Type: NDA, Contract, Employment Agreement" or Project names like "2022 Series B funding".

Multiple file format support

SignTime's e-signature platform allows you to upload multiple types of files, not just PDFs. Since SignTime is focused on improving your contract close time, it's a no-brainer for us to accept MS Word, Excel and Powerpoint files. We even accept pictures, so if you want to get an autograph done electronically don't hesitate to reach out!

Designation of order of signatories

SignTime's e-signature platform allows you to send sequentially or all at once, depending on how you want the contract to go. We understand that in some cultures, sending it to the customer without the boss's signature (well, e-signature) is a big no-no, so we are here to help sequence appropriately!

Special signature capabitlies required under Japanese law [aka Long-term signature (digital certificate + timestamp)]

What is a long-term signature?

PAdES(PDF Advanced Electronic Signatures) is a standard that, when combined with a digital signature and timestamp, you can clearly identify that this document has been certified. In SignTime's case, our e-signatures use the AmanoSecure certified timestamp.

What is a Time Stamp?

As required under Japanese law, we work with AmanoSecure Japan K.K. to provide secure NTP services, theoretically proving the data has not been tampered with in accordance with the Electronic Bookkeeping Act aka Digital Preservation Law.
