HMRC do not approve software. However, HMRC is currently working with software developers to test various software solutions to send the VAT through their API.
HMRC provides each software system with a unique reference so when that system links to HMRC’s API in the future it will be authenticated. Make sure that any software you are using for this purpose has been tested and the link to HMRC has been authenticated.
