The current invoice section, when you edit the invoice, does not allow for updating the weight of a product to get the final cost once packaged. Use case: A suppliers goods are priced/kg (weight). The products are listed per pack on the Take App (with estimated price) and can contain different qty's per pack. When an order is prepared, each pack is weighed to calculate the final price. The supplier wants to update the invoice with the weight to calculate the actual cost and send the final bill to the customer. Full Detail: We have prepared and attached a comprehensive use case and detailed suggestions on how this could be accomplished on the Take App for consideration.
