Hi Shazzy (Shazzy)
Thank you for your post. There are 2 options you can do in this situation:
- Set up two contact records for them: one as a supplier and one as a customer. Then record the sales as normal, then record a purchase for the materials.
- Offset your outstanding customer and supplier invoices by recording a contra payment, this way your customer can pay only the difference, but the full amounts are being recorded correctly for GST purposes.
