Subcontractor Invoices

[jaowen99]

I'm submitting my tax return for my first year as a sole trader. In my first tax year I made significantly below the personal allowance, so I'm submitting the return myself without an accountant.

I use subcontractors (NOT CIS) on a day to day basis. The subcontractors HAVE NOT been sending me invoices. I thought that it would be okay since my business has an online booking system which is also used by the subcontractors. It calculates and keeps a record of all payments made to subcontractors and which job each payment relates to.

We charge x amount to the end customer and the subcontractor receives a flat % of this amount. This is all recorded in our booking system for every job.

Would this be sufficient records in the eyes of HMRC without the invocies? I'm panicking now because if we need to go back and get invoices for every job completed, this is a mammoth task and also creates a huge amount of extra admin going forwards for subcontractors.
