Can a closed vat period be reopended?

Good to have you here,sonet-beninca.

Closing your books allows you to review the transactions recorded in the system to ensure they are accurate.  This is also to make sure all the adjustments made properly reflect in the business’ activity for the month. To be able to edit transactions in a closed period, you'll want to sign in to QuickBooks as the Master Admin, then change your closing date.

You can refer to this awesome article for more information about editing close books: Edit your closed books

I've got a link here where you can find articles about managing VAT: QuickBooks Online ZA | Value Added Tax
