Accounting & ERPUAElectronic document exchange for Ukraine — with a ready-made link for 1C and a connection built for everything else
Вчасно moves invoices, acts and other business documents between companies with a legally valid electronic signature attached. Companies on 1C get a ready-made link built specifically for it; everyone else connects through Вчасно's own interface, which pushes documents out of your system pre-filled with the counterparty's details already in place, instead of someone retyping them by hand.
Before someone re-types the counterparty's details into Вчасно by hand for every single document.
After the document is pushed out of the company's own system already filled in with those details, ready to sign.
Before signing thousands of outgoing documents one by one takes most of a working day.
After a high-volume signing connection lets the same batch of over 10,000 documents get signed in about 30 minutes, straight from the source system.
Before someone opens Вчасно separately to find the document and reply to the question there.
After the comment can be sent and received right from the connected system, without switching to a separate tab.
Before an older accounting tool has no way to talk to a modern connection interface at all.
After documents move instead by direct file transfer between servers, so the exchange still works without changing the older system.
For those who want to check: each point links to the official documentation page it comes from.
For ERP systems other than 1C, Вчасно offers a connection that lets documents formed in the ERP be pushed into the service already filled in with the counterparty's details.

Source: edi.vchasno.com.ua ↗ checked 2026-09-25Document exchange with an outside system is available two ways — through the usual connection, or through direct file transfer between servers — and the client picks whichever fits.
Source: edi.vchasno.com.ua ↗ checked 2026-09-25The vendor doesn't publish a separate numeric rate limit for this connection. Two real constraints are worth knowing: access only works with a unique key tied to one specific user, and the ready-made 1C link covers versions 7.7 and 8.2–8.3 (including managed forms) — anything outside that list goes through the general connection instead.
