Copy sales invoices & purchases from KashFlow to Xero

We are moving our accounts from KashFlow to Xero for various reasons.

We need 120 purchase invoices in Kashflow copying to Xero

And approximately 200 sales invoices copying to Xero.

And approximately 90 customers / suppliers.

Its a very simple, very boring copy and past exercise unfortunately :( Open invoice in KashFlow, copy details, paste into Xero. You don't need accounting experience.

Need it doing asap.

Thanks
