Hi,
Can you send me Excel file for review please?
You will use software locally in your system right?
Because you have set project budget very low, I would highlight the features accordingly.
For database, I will not use much complex database and use simple json based database.
Or you can also use Excel file as a database to store supplier, price list data.
You will be able to view these list and any purchase order later, which will be also saved.
Thanks
