Finvalda, JARS Apskaita and other accounting software
Sales and purchase invoices, cash receipts and payments from your online shop, CRM or till system reach your accounting software automatically – with no retyping and no duplicates.
We decide which documents go to accounting and how they match your customers, items, VAT codes and warehouses.
We connect through the software's API, and if it is installed on your own server, a small relay agent runs inside your network.
New documents are transferred at once or on a schedule.
Duplicate protection makes sure a document reaches the books exactly once and never bounces back and forth between systems.
A document that can't go through waits with the reason and is shown to a person, while the others keep flowing.
Where needed, payments and debts are passed from accounting back to the CRM system.
Every day you see how many documents were transferred and which ones are waiting for a decision.

No. We connect to the accounting software you already use through its API, a data import or, if there is no other way, by having the AI operate the program itself. You keep working in it as usual.
It isn't lost: it waits in a queue with the reason, and you are told about it. Once the cause is fixed, the document goes through once, with no duplicates.
Yes. All sources send their data through the same integration, which checks customers, items and VAT codes and guards against duplicates. The documents arrive in your books in the same tidy form, whichever system they came from.
A few sentences are enough – we'll reply and talk through how we could help.
