Software switchovers mid VAT Quarter

If a company switches their software product midway through a VAT quarter, and the new software only contains opening balances and not full VAT records for the previous transactions, how should firms submit their VAT return. e.g. a firm completed their first month of the VAT quarter in one software package, and the other two months in another software package. How would you recommend the VAT return is completed?

Hi Sir Vatalot,
VAT returns can only be submitted by one software product, two submissions from two products for the same overall VAT period would not be accepted.
If the information is held over two products, you would need to arrange for the data to be input into one software product to allow the submission of the full VAT return.
Thank you.
