Hi, I have experience working with many finance systems for large global companies including set up of systems, data importing and the most important part; the design of processes surrounding your problem. I have experience using Xero as i use it for my own business. Xero has a CSV import functionality, which is probably your quickest way of managing the import of data. I am currently based in Singapore and can provide you formal invoices from my UK company mentioning the value of services in AUD so you can easily account for my services. I can also provide training through progress such as teamviewer if needed. Would be glad to discuss more such as where is the data you are looking to import? is it one time or ongoing? What other systems are you using for contact management, order tracking etc and how you may like to link these systems.
Regards,
Thomas
