I need an expert in C# to integrate my Point of Sale/Enterprise Resource Planning (POS/ERP) system with Business Central Online. The goal is seamless syncing of different modules, including, but not limited to:

- Customers
- Inventory (send inventory to BC at invoice, and get inventory on demand)

- Products, Categories, Price List.

Experience with developing Microsoft Business Central APIs and C# .net Core professional is imperative for this role. Experience with similar projects will be highly valued.

We already have a similar code we made integration with SAP Business One for example how to do integration...
We have coded someone to start integrating directly with Microsoft Business Central.

we can share this code to have the fastest development, and we also have the code of a previous developer who made Microsoft Business Central.
