I’d like to suggest an improvement for the current duplicate detection function. At the moment, it seems the system only checks for duplicates based on amount, which often causes incorrect duplicate flags. For example, bills with the same amount but different invoice numbers and dates are being flagged unnecessarily which becomes quite frustrating.

It would be much more effective if the system allowed us to define the duplicate criteria ourselves, similar to the "recode" function. For example, users could choose from options such as:

Duplicate by Amount + Date

Duplicate by Invoice Number + Amount

This flexibility would reduce false positives and make the duplicate function more accurate and useful.

This functionality shouldn't have been released until it had been tested properly.

This is important as duplicate bills keeps telling me that the same bills are duplicates. Once I have said 'keep all', then it shouldn't ask me again. Today (29 Aug 25) I got a duplicate bills notification for 2 paid bills dated Jun 25, over 3 months ago!

Can we please have the system stop telling us that there are duplicate bills after one has been voided? Once a bill has been voided, it no longer poses a threat so why does the system still tell us that there are duplicates?

Agreed. Or even better would be to improve the functionality so that a draft bills are not included when the system is scanning for potential duplicates. These are the only ones that I have ever been notified about, no actual duplicates.

I am fed up with this too. A simple account option to silence them is needed. There are other popups for things like your payment system that regularly get in the way. A dismiss button should be permanent, not a snooze.

Duplicate bills should not flag bills from the same supplier for the same amount on or around the same day of each month.

Please can we have the duplicate bills notifications fixed? Currently we are notified via the pop up that there are duplicate bills - which is great and very helpful! However, once we have clicked into it and voided the duplicates.. the same duplicate error message still pops up again despite us having just sorted. Requiring us to go back into it and click keep all, even though there is nothing we can do as we have already voided the duplicate and obviously would not want to void the active one, and with nothing that can be done to the voided one it seems unnecessary and frustrating having to double up. If we have gone in and sorted the duplicates by selecting keep all or voiding one, then that should be final and we dont need to see the same duplicate notification again

Wish we could turn this off. As you say it just flags recurring monthly bills and has never once flagged an actual duplicate bill. Pointless feature for us and would be great to be able to disable it.

When posting bills from HubDoc to Xero, they sit in "Awaiting Payment." Xero recently introduced a function to detect duplicate bills, but I found it to be ineffective.
The system fails to identify actual duplicate bills, as it primarily matches invoice numbers. However, invoice numbers can vary due to auto-syncing from HubDoc, making this method unreliable. In most cases, duplicate bills share the same amount and date rather than the invoice number. The matching criteria should prioritize these factors to ensure accuracy in detecting duplicates.

Also find this annoying. I have voided geenuine duplicates for them to still appear in the 'Duplicate bill' review. When i click you can clearly see oneis voided. CAn you pease fix this glitch. It wastes so much time.

This is infuriating as it is comparing many old items (in previous years) with the same amount and suggesting I review them. When marked as keep it brings them back again next time with a "previously kept" marker - complete waste of time and a real risk that genuine recent duplications may get missed in the mass of nonsense

Xeros duplicated bill theory. 1. Uploaded bills are sent to the draft section of Bills. 2. A Draft bill is clicked on and you are taken to the editing screen. 3. If the bill is duplicated, Xero points this out. - This is where the problem is. XEROS message that says THSI BILL IS DUPLICATED - IS NOT a true statement, as it has YET to become a BILL. IT IS STILL A DRAFT bill. Xero needs to be clear in their message in the editing section that there is a duplicate BILL (already entered on the system and sitting as a supplier bill) or DRAFT (sitting in drafts and NOT yet a supplier bill) Its extremely time consuming to have to to view all duplicate bills, click on them to see if they are deleted, duplicated, or on the system that Xero views as duplicates in seperate places. There are multiple ways or checking these that are long and unnecessary. Keeping it simplified while in the supplier process would be fantastic.

It's an incredible functionality:
1. it finds a duplicate with bill paid a year ago
2. it does not offer to disable this warning for some entities.

Please either allow to disable in full or make it smarter!

This is a frustration I have as we have quite a few reoccurring bills that are always flagged as duplicates, the system should be able to determine if a bill is truly a duplicate of simply reoccurring or have a feature where reoccurring bills can have an additional reference field to distinguish duplicates from reoccurring bills

Currently repeating bills use the same reference number and flag as duplicates, it would be very helpful for repeating bills that require the same reference number e.g payment plans, vehicle finance, insurances ect. had a distinction when repeated to avoid having duplicates.
This could be as simple as being able to have a custom placeholder for the reference field.

All of the duplicate bills highlighted have been recurring invoices. Adding the ability to turn this off for those suppliers could make it a more useful function as it may actually highlight an issue at some point in the future.

The Leave Feedback button doesn't link to anything on the "Thankyou" page.

Yeah this feature has never once picked up an actual duplicate. It just displays recurring subscription invoices.

Very annoying. Would love to be able to disable it.

yes please let us turn this off - this is the worst example of a new feature added to Xero in my 12 years.
There are so many apps that send thru a daily or regular bill to Xero as part of the sync - Lightspeed, REX just to name two.
If this feature was to be useful we need to be able to ignore those suppliers
