[ FREQUENT QUESTIONS ]

Answers to common questions from customers

Key details regarding terms, independent website editing, and rights transfer.

Yes, definitely. According to the Law of Ukraine «On Electronic Trust Services» and «On Electronic Documents and Electronic Document Circulation», a document signed with a qualified electronic signature (KEP) or Diia.Signature has exactly the same legal force as a paper document with a handwritten signature and wet seal.

For your counterparties, obtaining and signing incoming documents in «Vchasno» is absolutely free! The client just needs to click the link from the letter or messenger and apply their qualified electronic signature or sign through «Diyu» within 30 seconds without any payments.

With the webhooks we configure, the status in your CRM updates automatically. The manager receives an internal notification, the deal automatically moves to the next stage, and the signed PDF with qualified electronic signature marks is automatically attached to the customer record.

Yes, exactly for this we are developing a batch sending module. Your accounting system forms a register of acts with one click, automatically sends them to «Vchasno» to all subscribers and puts them on signature monitoring.

We integrate «Vchasno» with any systems: KeyCRM, SalesDrive, HubSpot, Bitrix24, Zoho, 1C/BAS, IT-Enterprise, as well as with self-written ERP on PHP, Python, Node.js through the official «Vchasno» REST API.
