I tested creating an invoice, receipt, payment, sales order and a delivery note on the Cloud Edition but could not reproduce this issue. None of the forms were duplicated. Please provide screen shots of the duplicated forms and the Manager version you are using. ---

the duplicate not a copy or colon, it is it’s self duplicate, when you make a sales invoice, receipt or payment or even inter account transfer and create the transection it’s self become double with same serial sometimes or new serial sometimes. that is the problem and still 03/10/2025 going. ---

when you create a transection the duplicate error still exists, i am using the last version **25.10.3.2869,** I reset the domain and no there is no solution still, some transection may duplicate 3 to 4 times, we have tribble to make correct entry. this is a transection we created once and it become quadrable. ![Duplicate error](https://us1.discourse-cdn.com/flex019/uploads/manager1/original/3X/4/a/4a872856316108514bdb1cd89bd13c1f1fab3898.png) ---

I haven’t experienced this issue on either the Cloud or Desktop Edition. Does this happen across all your business files, or just one? If it’s limited to a single business file, I recommend contacting the developer directly and sharing that file so they can investigate the cause. Alternatively, you could try creating a new test business and see if the same issue occurs. ---

This accurs with some transections but it is the all transection types like sales invoice, purchase, payment, receipt and inter accounts transfer ---

It would seem that this has something to do your setup and/or internet connection - it’s as if you PC is retransmitting the data to the cloud server ---
