Greetings

I am currently working on a web application that manages Subscriptions, Invoices and Payments. I have done exports for the following Sage One, Quickbooks however, it seems like those to are much better documented online then Pastel. Keep in mind that I do not own Pastel and I can't seem to find any type of trail version. I have never used Pastel.

So my question is bascially what would the flow be of importing Customers, Invoices and Payments into Pastel? The invoices will be created on the web application and managed from there.

I read up on multiple sources that to find the format required I need to go look at the help menu item in Pastel, but like I mentioned I don't own Pastel. If the sharing of this is a big NO NO from pastel side I understand otherwise any information will be greatly appriciated.
