Sage 50 to XERO conversion

I am doing a historical transfer of data from SAGE50 to XERO in which I need to see the line-by-line data that makes up the Aged Debtors and Aged Creditors as at 30.4.2024, plus each line of transactions that have happened since the 1st May 2024 onwards up to date.

I can provide csv output from Sage 50 for the following, Customers, Suppliers, Sales Day Books and Purchase Day Books.

There are input csv sheets required to import to XERO, I am looking for someone to accurately convert the data from the SAGE 50 csv format into the XERO csv format to the extent that the Xero csv format allows.

This project is required asap but I can allow up to 1 month to achieve.
