Preparing for a VAT return should not mean hunting through old emails, reshaping bank CSVs, or trying to remember why a figure moved. A return is easier to trust when the underlying sales, purchases, and evidence are already in place.
Start before the filing deadline
Check that invoices, bills, expenses, and bank matching are in a reasonable state before you look at the draft return. Filing readiness depends on record quality, not just box totals.
Review what changed
Look at the draft return in the context of the ledgers and reports behind it. Large movements should be explainable. If they are not, that is a signal to inspect the underlying postings instead of guessing.
What software should help with
A good product should surface draft figures, source context, and the next review steps clearly. DII Accounts is designed to make VAT preparation calmer, not noisier.
When to move into a proper workflow
If your return process still depends on manual reshaping, start managing VAT in one workspace before the next filing period arrives.
