Hi Victoria Barrett

Thanks for reaching out. Did you ever find an answer for this issue? Here's an article that says:

"When creating a purchases invoice, the default Ledger Account used is 5000 - cost of Sales goods, but you can select 5010- cost of sales material or 7100 rent and rates , 7200 Gas and electrics etc, according to your needs."

You may want to come up with amounts per pound of non-stock supplies that get consumed during processing that are then billed on an invoice as a line item to the 5010-cost of sales material account; that or if when filling out an invoice  "If you select the template "Service-based", the following only is displayed: Item ​Description, Tax, Net amount.

If you are still looking for guidance, please let us know and we can try to point you in the right direction or suggest some resources or next steps.

Warm Regards,

Erzsi
