Inputting VAT Pre-Registration expenses for first VAT Return

Inputting VAT Pre-Registration expenses for first VAT Return

Hi Zoho,

I've just registered for VAT and am setting up Zoho to handle calculations and VAT return submissions. I'm struggling to figure out how to input the last 4 years worth of expenses into Zoho so that they're calculated in the VAT module. When I try to add the VAT to the expense it tells me I can't because it's outside of the VAT period.

Is there any reason I shouldn't just do these calculations separately (outside of Zoho) and manually add them into Box 4 of the return as an Adjustment?

Thanks,
