Your Viber bot tells clients their order status and debt from 1С/BAS, takes reorders, and reminds about unpaid invoices
Many clients in Ukraine live in Viber: they write there, they read there, they ignore email. The accounting lives in 1С/BAS, and the manager carries answers between the two by hand: «is it shipped», «how much do I owe», «send the invoice again». The 1С/BAS ↔ Viber pair connects your Viber bot to 1С/BAS: a subscribed client gets the order status and the tracking number the moment it changes, sees their balance, repeats a past order with one button and gets a reminder about an invoice that is due. Below: what exactly moves, which scenarios we cover and which capabilities of both systems we rely on.
Before the client writes to the manager's personal Viber, the manager checks 1С/BAS and replies when they get a moment.
After the client receives the status and tracking number from 1С/BAS the minute the warehouse posts the shipment, without asking.
Before the accountant prints the overdue list on Monday and the manager spends the day calling.
After the bot reminds each client in Viber a few days before the due date with the invoice attached, and confirms when 1С/BAS posts the payment.
Before a shop orders the same twenty items every week by phone, and the manager types them in from hearing.
After the client presses «repeat last order» in the bot, adjusts the quantity, and the order lands in 1С/BAS as a document.
Before the client asks for the invoice in a chat, the manager asks the accountant, the accountant sends it by mail an hour later.
After the client presses «my balance» and gets the unpaid invoices from 1С/BAS as files, in the same chat.

The official BAS support portal documents its integration technologies under the title «Технології інтеграції 1С:Підприємства 8.3» — BAS is built on the 1C:Enterprise 8.3 platform.

Source: www.viber.com ↗ checked 2026-09-28The limits come from both systems. The bot can only message people who subscribed to it by writing first, and Viber does not hand out a list of subscribers, so clients have to come to the bot themselves by a link or a QR code. Since February 2024 Viber runs bots on commercial terms, which you agree with Viber directly. A broadcast to many subscribers goes out in batches, not in one go. Balances and statuses are only as fresh as the 1С/BAS data at that moment. 1С/BAS is on the official prohibited software list: we do not take projects for state bodies, critical infrastructure or systems with state data, and with private businesses we discuss the risk openly.
