Run a free check for duplicates Or connect Xero and start the $49 Clean-up Pass
You sign in with Xero first. The scan needs no card and writes nothing to Xero. You see the count, the total and the first 10 rows.
What Xero checks on its own
Xero reviews bills for you. Under Purchases, Bills, click the menu icon and select Review duplicate bills. Xero compares the Contact, Reference and Total of all bills and credit notes, and flags them when all three match (Xero Central, Review duplicate bills or credit notes, checked 15 November 2026). The article covers bills and credit notes only, so a bill copied with a different reference is not flagged, and sales invoices are outside it. Our guide on how to find duplicate invoices and bills in Xero has the report and formula route for invoices.
Side by side for the duplicate job
Xenon Connect cells come from its own pages, opened on 15 November 2026. Where its pages say nothing about a point, the row is left out.
| Xenon Connect | Duplicate Finder (Unapprove) | |
|---|---|---|
| What it checks | A suite of bookkeeping checks. Its list includes duplicate supplier bills, duplicate customer invoices and duplicate contacts, with unreconciled bank activity and old unpaid bills | Sales invoices and bills only: the same kind, contact, currency and total, dated the same day, or less than 7 days apart with the same reference |
| Ledgers | Xero, QuickBooks Online, FreeAgent and Sage | Xero only |
| Fixing what it finds | Its home page says you can push back corrections in 1 click | A paid plan sends the extra sales invoices to a bulk void with a preview, a backup file and a typed confirmation. Duplicate bills are listed, and you open them from the list |
| Pricing model | Monthly subscription, cancel any time, 10% off yearly. With the UK selected: Business Owner £9 + VAT a month for 1 organisation. Firm plans from £22.50 + VAT a month for 5 organisations | Unapprove plans, per organisation: $49 once for a 30-day Clean-up Pass, $39 a month or $290 a year. Tax is added at checkout |
| Free tier | 14-day free trial | The scan, as often as you like, with no card: how many possible duplicates, their total and the first 10 rows |
| Reads or writes | It pushes corrections back to the ledger | The scan only reads. A void runs only after you confirm it, from a scan less than 24 hours old |
| Other jobs | Financial KPIs (Xenon Insight), a compliance workflow (Xenon Systemise) and alert notifications | Bulk void and unapprove to draft, write-offs, attachment and invoice PDF export |

Which one fits
- A practice that checks many client files every month, on Xero and other ledgers, for more than duplicates: Xenon Connect. It is built for that, with workflow and alerts.
- One Xero organisation with copies to remove now, after an import ran twice or a sync posted orders again: Duplicate Finder. Run the free scan to see the count and the total before you pay.
- Bills only, matching on contact, reference and total: Xero's own Review duplicate bills is free and already there.
Duplicate Finder lists possible duplicates and voids nothing by itself. It never suggests voiding a copy with a payment or a credit on it, and a void in Xero cannot be undone. For the void itself, see how to void multiple approved invoices in Xero at once, and for other bulk void tools, Unapprove vs Bulkdozer vs Bulk Void vs SaasAnt.
Questions before you choose
What is a good alternative to Xenon Connect for duplicate bills?
For finding and clearing duplicates in one Xero organisation, Duplicate Finder in Unapprove: a free scan of sales invoices and bills, then a paid plan to list them all and void the extra sales invoices. For monthly health checks across many clients, Xenon Connect does more.
Does Xero find duplicate bills by itself?
Yes, for bills and credit notes. Review duplicate bills flags those whose Contact, Reference and Total all match. A copy with a different reference is not flagged, and the article does not cover sales invoices.
How much does Xenon Connect cost?
With the UK selected on its pricing page on 15 November 2026: £9 + VAT a month for one organisation on the Business Owner plan, and firm plans from £22.50 + VAT a month for 5 organisations, with a 14-day free trial. Check the page for your country before you buy.
Is the duplicate scan really free?
Yes. The scan reads every sales invoice and bill and shows how many possible duplicates there are, their total and the first 10 rows, with no card. The full list, the CSV and the bulk void come with a paid Unapprove plan.
Will it void a duplicate that has a payment on it?
No. A copy with a payment or a credit on it is listed so you can see it, marked to leave alone, and never suggested for voiding. Remove the payment yourself first if that copy really is the extra one.
See how Duplicate Finder decides or check the current plans. FOUNDING40 takes 40% off the first payment until 30 November 2026. An unused Unapprove pass is refundable within 14 days.
