To avoid having the same bill in your books twice, MakersHub identifies and flags duplicates by checking the invoice number and vendor name against bills that have been processed in MakersHub. MakersHub will flag a duplicate bill in red (shown below). Select **View ID** to verify whether or not it is a duplicate. ![](https://cdn.document360.io/1b554e23-2d1e-483c-9fb1-9be0ba01e89c/Images/Documentation/Duplicate Flagged.png) When you select **Merge**, the copy you are viewing will become the dominant version and remain in your bill/receipt queue, the other copy will be added as a supporting document. > [!WARNING] > Cannot Unmerge a Bill > > If you have edited or coded a bill, be sure to click merge on the bill you have made the changes to as once you merge the bills, it cannot be undone. ![](https://cdn.document360.io/1b554e23-2d1e-483c-9fb1-9be0ba01e89c/Images/Documentation/Merge Duplicates.png) Under **Additional Documents** you will see, the merged record appear as an attachment. ![](https://cdn.document360.io/1b554e23-2d1e-483c-9fb1-9be0ba01e89c/Images/Documentation/Merged Record as Supporting Doc.png)
