Is GraphQL API suitable for supermarket POS(Point-Of-Sales) application?

I am developing a smart POS application that serves as an integrated software solution that facilitates efficient and modern point-of-sale operations for supermarkets. This system has the following functionalities.

1. Sales processing and transaction management
2. Inventory management
3. Employee management
4. Report and Analytics
5. E-commerce integration
6. Multi-Store support
7. Customer management

I chose ReactJS for the front-end, Springboot for the back-end, and PostgreSQL as a database. I want to know whether QraphQL API is ssuitable for this development.
