I've got some details concerning the VAT reversal scheme in QuickBooks.
It has started last October 1, 2019, and specific for the VAT collected in the building and construction industry.
The customers that are receiving the service will pay the VAT due to HMRC instead of paying the supplier. It applies to business enrolled for VAT in the UK. It will affect if you supply or received particularised services that listed under the Construction Industry Scheme (CIS).
