Upload a spreadsheet with invoices

I’m looking at using invoiceninja.com and I’m trying to figure out if I can upload a spreadsheet with a list of invoices (with charge detail, due dates etc) without using a third party addin. I want to automate creating the invoices, but not send them without reviewing first. Any ideas or suggestions are appreciated.

So far the only service that I can find that can directly import invoices is Zoho, but I don’t like the UI and I’d prefer to support a smaller company.



It’s possible to import invoices as a CSV file
