Modern businesses can no longer operate efficiently with isolated systems. A CRM for sales and an ERP for accounting must function as a single mechanism. That is why integrating Zoho CRM with BAS CUP / 1C is becoming critically important for companies that want to scale, minimize manual work, and avoid data errors.

1. Initial conditions and accounting logic in BAS / 1C

In the current 1C configuration, the following principle is used:

One partner = One counterparty
(no separation between partners and counterparties)

This approach simplifies integration, reduces the number of duplicates, and allows the CRM to serve as the primary source of truth for the customer database.

2. Business requirements for Zoho CRM ↔ BAS CUP / 1C integration

1. Creating and editing orders from Zoho CRM

The sales manager works exclusively in Zoho CRM:

• creates customer orders;
• adds products;
• sees up-to-date prices and stock availability.

From this point, the system works automatically:

• the order is transferred to 1C:

  – either every 3–5 minutes;
  – almost instantly (2–3 seconds) via an open 1C API endpoint;

• from 1C back to CRM the system returns:

  – the document number;
  – the current order status.

If the order is edited in CRM, the data is automatically updated in 1C, without any manual involvement from the accountant or logistics team.

2. Processing B2C orders without a counterparty

For online orders or incoming requests where the counterparty is not defined, the system uses technical counterparties, for example:

• “Main Internet customer”
• “Main ERecovery customer”
• “Main Office customer”
• “Main IF customer”

This approach allows you to:

• avoid blocking order creation;
• maintain accurate accounting in 1C;
• prevent chaos in the counterparty directory.

3. Sales documents and warehouse operations

Based on the order, 1C generates a sales document. The realization (sales confirmation) is automatically returned to Zoho CRM, including: date, warehouse, product list, status.

The sales manager sees real-time stock levels across three warehouses, products are synchronized every 3–5 minutes, new products created in 1C automatically appear in CRM.

The manager can also initiate warehouse transfers by creating a document in CRM. This document is processed in 1C, and the status is returned back to CRM.

3. Role separation between Zoho CRM and BAS CUP / 1C

Zoho CRM — sales manager responsibility

• Working with customers: creating contacts and companies.
• Creating orders and commercial proposals.

• Creating production tasks and assignments for delivery staff.

BAS CUP / 1C — accounting and operations

• Price management, discounts, promotions, VAT.
• Sales posting and financial settlements.
• Production planning and execution control.

4. Additional functionality in Zoho CRM

• Price recalculation based on the offer with the ability to manually edit.
• Display of stock availability during product selection.
• Creation of Warehouse Transfer and Production Tasks documents directly from CRM.

5. Conclusion

The integration of Zoho CRM + BAS CUP / 1C creates a single digital business ecosystem covering sales, warehouse operations, and production. It allows companies to:

• reduce manual work and eliminate duplicated data;
• track orders at every stage;
• see customers’ financial status directly in CRM;
• scale the business quickly without increasing staff.

A properly configured integration becomes a key operational tool that significantly improves company efficiency and sales team productivity.
