Which export/import do I need? (restaurant POS integration)

I work for an organization that makes a restaurant Point of Sale.  We have a customer with Peachtree 2011 and they've sent us information from the help files about importing into that version.  We want to import sales information into the G/L but I'm not sure which of the three types of imports I'm looking for.

They sent info on:

Cash receipts Journal  Fields

Sales Order Journal Fields

Sales Journal Fields

Is someone familiar with these reports who could shed some light on which of the 3 specs above (or possibly a different one) we should make our system export to?  Basically we just have restaurants who have sales for food and beverage and want to post these sales figures to the appropriate G/L in Sage/Peachtree.
