- Product Stock Actions
Overview
This node integrates with the Tiny ERP system to manage product stock levels. Specifically, the "Product Stock" resource with the "Update Stock" operation allows users to update the quantity of a specific product in a particular deposit (warehouse or storage location). This is useful for businesses that need to keep their inventory synchronized between Tiny ERP and other systems or workflows.
Typical use cases include:
- Automatically adjusting stock quantities after sales or returns.
- Synchronizing stock levels from external inventory management systems.
- Updating stock when new shipments arrive at specific deposits.
For example, if a warehouse receives 100 units of a product, this node can update the stock quantity for that product in the corresponding deposit within Tiny ERP.
