How much VAT do I owe this quarter, and when does it need paying?
Hi Dave,
Your VAT return for the quarter to 31 October Xero, VAT return: the quarter’s end date shows £3,412.60 Xero, VAT return: net VAT to pay HMRC to pay HMRC. Payment is due by 7 December Worked out: one month and seven days after 31 October .
If you pay by Direct Debit, HMRC collects it a few days after that, so you don’t need to do anything.
Thanks, Aaron
£3,412.60 and 31 October from the VAT return in Xero. Due date worked out from the period end.

Most AI tools are built for US firms or big practices. Not for a UK practice where the partners answer client emails themselves.
Aaron and Laurence run ABLM Associates, a small UK practice, and write Reconciled, the weekly newsletter on AI for UK accountants. Proovva Inbox is built around how they answer their own clients.
Questions accountants ask first
No. The draft waits in your Outlook Drafts with your signature. Nothing goes until you press Send.
Every figure links to the record it came from, so checking takes a click. If Proovva Inbox can’t find a figure, it says so rather than guessing.
Only you see your inbox and drafts, not colleagues or practice admins. Proovva Inbox reads your ledger and never changes your books. Your emails only go to AI providers that don’t store or train on them, and your data is stored in the EU. It’s built with the PCRT guidance on AI in mind: client data never goes into a public AI tool, and a person reviews every draft.
If your practice uses Microsoft 365, yes, once for the practice, and we’ll walk your admin through it on the set-up call. Personal Outlook accounts don’t need approval.
Outlook for work email, either Microsoft 365 or a personal Outlook account, and Xero or FreeAgent. Gmail support is coming. If you use Gmail, join the waitlist for the next 10 and we’ll tell you when it’s ready.
No. Keep it for everything else. Proovva Inbox only drafts replies it can answer from the client’s records.
Your £20 then includes a set number of drafts each month, with extra drafts charged per draft. We’re setting both with real usage from the first 10, and we’ll confirm them at least 30 days before your fourth month. If they don’t suit you, you can cancel.
Every week you wait costs about £500 in client email time.
