In AroFlo, your record of a supplier invoice is known as a Bill and it is linked to a purchase order.
At this stage, bills can only be created and accessed via purchase orders. In future, we plan on making bills available in other areas so that you'll be able to create bills for other outgoings that are not purchase order related or job specific.
Track every supplier delivery and expense incurred
Record multiple bills against a single purchase order for items delivered in batches
