I contracted some work to an electrician as it was required for the job. I need to include this in the invoice to the customer. What category is best for recording this?

He is Vat registered. He has provided me with an invoice for work and materials he has carried out on a job for me to include in my  invoice to the customer. 

Im just looking for a category to mark this under. I don't want to add it as materials as it isn't. And i don't want to mark it as labour as that is what i earn as labour for solely me. 

Thank you for the additional details, psellick8.

You'll want to create a bill or expense to record a paying subcontractor. 

When creating your transaction, select your subcontractor, QuickBooks will use their CIS rate to calculate the CIS to deduct (CIS withheld). If materials are a part of this transaction, you can add these on here too.

You can read more on the details of how QuickBooks calculates Construction Industry Scheme: CIS in QuickBooks Online.

Please let me know if you have other concerns.
