What to do when a Xero payment has no invoice
You're working through your bank feed in Xero and you hit one that stops you: a £310 payment to a supplier you only half-remember, with no invoice attached to it. You know you need that document — for your records, and to reclaim the VAT — and right now it's nowhere.
It's a small, common, oddly stressful moment. Here's how to deal with the one in front of you, and then how to make sure it stops happening every month.
Why a payment ends up with no invoice
A missing invoice almost always traces back to one of three causes, and knowing which one you're dealing with tells you where to look.
The invoice was emailed, and it got buried. It did arrive — but under a subject line you didn't recognise, from a "no-reply" address, or into an inbox you don't check often. It's sitting in your email somewhere; you just haven't found it.
The invoice lives on a portal. A lot of suppliers — software companies, telecoms, utilities — don't attach the invoice to anything. They send a "your bill is ready" email and leave the actual document behind a login. If you never logged in, you never got it.
No invoice was ever sent. Some suppliers, especially smaller ones and certain subscriptions, simply take the payment and move on. There's no email to find and no portal to check, because nothing was issued. This is the hardest kind to catch, because nothing anywhere is telling you it's missing. It's the payment itself that's the only clue.
How to track down the missing invoice
Work through these in order — most invoices turn up by step three.
Identify the supplier from the bank descriptor. Bank feeds show garbled text like GOOGLE *GSUITE_xj4 or AMZN MKTP. That still maps to a real vendor. Work out who it is — that's the name you'll search for everywhere else.
Search your email properly. Search for the supplier name, then the exact amount, then the month. Check spam, and check any shared or account inboxes as well as your own. Emailed invoices hide better than you'd expect, so search on more than one term before giving up.
Check the supplier's portal or account. If it's a SaaS tool or a utility, log in and look under billing or invoices. You can almost always download a PDF of the exact charge, often going back months or years.
Ask the supplier directly. If nothing exists, email them and ask for a VAT invoice for that specific date and amount. Most will issue one without fuss — they're required to, if you're both VAT-registered.
Attach it in Xero. Once you have the document, attach it to the transaction so the record is complete and you don't have to do this again for the same payment.
Keep in mind that for VAT reclaim and HMRC records you need a valid VAT invoice, and you're generally required to keep it for six years. (This is general guidance, not tax advice — check HMRC's rules or your accountant for your own situation.)
How to stop it happening every month
Everything above works for one payment. The problem is that chasing invoices one payment at a time doesn't scale — and the invoices you most need to worry about are the silent ones you'll never think to look for.
The only reliable fix is to reconcile systematically: check every payment against your invoices, every month, and deal with the gaps while they're still fresh in memory. Do that and a missing invoice becomes a five-minute task in week one, instead of an archaeology project next January.
That's exactly the job PaperHound does automatically. It reads your Xero bank feed, matches every payment to its supplier invoice, and finds the missing documents in your email and attaches them. Anything it can't find, it flags — with a direct link to the supplier — so your list of "payments with no invoice" is already empty by the time you, or an auditor, come looking.
The shift is subtle but it's the whole point: instead of waiting to notice a missing invoice by accident, you start from the payment and work backwards, so nothing can quietly slip through.
Frequently asked questions
Do I legally need an invoice for every payment?
For VAT reclaim and HMRC records, yes — you need a valid VAT invoice to support a business expense, and you should keep it for around six years. Without it, you may not be able to reclaim the VAT on that cost.
What if the supplier never sent an invoice?
Ask them for one. Email the supplier and request a VAT invoice for the specific date and amount; most will issue it on request, and VAT-registered suppliers are generally obliged to.
How do I work out which supplier a Xero payment relates to?
Start with the bank feed descriptor — even garbled text like GOOGLE *GSUITE identifies the vendor. Then search your email and the supplier's billing portal for a matching amount and date.
Isn't bank reconciliation in Xero enough?
Bank reconciliation matches transactions to bills that already exist in Xero. If a bill was never captured in the first place, reconciliation passes straight over it — which is how missing invoices stay invisible. Catching them means checking every payment has an invoice, not just matching the ones that do.
