I am looking for an alternative order and invoicing module that integrates with Adagio products. The module must be able to gather several orders to generate 1 (one) invoice to a particular customer. This feature is very useful especially in the vehicle spare parts business where a customer can place tens of orders in a day and request one invoice (after order confirmation of delivery and changes if any) to reduce paperwork. Vehicle spare parts is a huge and growing business in the Asean countries.
