Labour and materials in one lump
The deduction comes off labour only. Put the two together on one line and the contractor either deducts from the whole amount, which costs you money, or hands it back for a rewrite.

Labour split from materials, the deduction worked out at your rate, your UTR on the document. Written on your phone before you leave site.

The problem
The deduction comes off labour only. Put the two together on one line and the contractor either deducts from the whole amount, which costs you money, or hands it back for a rewrite.
Registered subcontractors are deducted at 20 percent and unregistered ones at 30. Guessing on a spreadsheet template is how the figures stop matching the contractor's monthly return.
The office needs your Unique Taxpayer Reference to verify you before they can pay. Leave it off and the invoice sits in a pile until someone rings you for it.
What Bily does
Bily asks once whether contractors deduct CIS from you. Say yes and every invoice from then on carries the right shape.
