Title: Request for Online Marketplace Integration and Automatic Stock Synchronization

I would like to request an integration feature in My Bill Book with online marketplaces such as Amazon, Flipkart, and Meesho. Similar to systems like Uniware, the application should allow users to connect their online seller accounts directly with My Bill Book.

With this integration, stock levels should automatically update whenever a sale is made on any connected platform (Amazon, Flipkart, Meesho, etc.). Currently, we have to update the stock manually after every online sale, which is time-consuming and increases the chances of errors.

Implementing this feature would help sellers manage inventory more efficiently and keep stock synchronized across all sales channels.
