I have recently started doing the books for a new client, I have already posted around 130 invoices to Sage (Instant V14) that has built up over the year. I have just learned that she is registered under the VAT cash accounting scheme, I guess I should've checked when I was first setting her up on Sage but didnt. When I try to change it over to cash accounting scheme under company preferences it states it cannot as there are unreconciled VAT transactions.
She has already done 3 VAT returns previously using her own spreadsheets but really needs computerised accounts setting up for her annual tax return coming up soon.
