Integrate CS Cart with Odoo or another ERP

It is necessary to set up automated integration between the online store (CS-Cart) and the inventory and sales management system for effective data synchronization between online and offline points of sale (2 pieces).

Task description: Inventory management system:
A freelancer can choose a suitable system (for example, Odoo/MySklad/1C, etc.) for inventory and sales management, which will be synchronized with CS-Cart.The main requirement is that the system must support multi-warehouse (different offline points of sale) and be compatible with CS-Cart via API or other integration modules.
When a product is sold through an online store, it must be reserved in the inventory management system and is not available for sale in offline stores until the online order is completed.
Sellers in offline stores should be able to scan product barcodes through a tablet or PC, and the system should display the product and its availability.
Integration should work correctly with the multilingual structure of the site (the site has three languages: Russian, English and Georgian).
Sales and orders need to be integrated between CS-Cart and the selected system in order for all orders (both online and offline) to be displayed in the inventory management system.
Before starting the integration on the main site, you need to test the system on a test environment (a copy of the site). Additional points: It is important that the integration process does not affect the operation of the current site and is smooth for customers
such as EGAIS control, VAT calculations, etc., are not relevant, as well as
laws of the Russian Federation on personal data.
