Import customer invoices from csv to Odoo 16

I am looking for a freelancer who can help me import customer invoices from a standard csv format into Odoo 16. I have already formatted the csv file and do not need any assistance with formatting. Users should not be able to modify the imported invoices.

Skills and experience needed for this project:
- Proficiency in Odoo 16
- Experience with importing data from csv files
- Attention to detail to ensure accurate and error-free importing.
