I am using integrations that assign the sales receipt number with a prefix . The problem is that manually entered sales receipts are incrementing the number causing dups

Hi there, jwd.

We don't have a direct option for configuring number sequence in integrated from manual sales receipt. QBO uses sticky numbering system, wherein the last 3–5 transaction numbers entered set the sequence for the next one. When integrations sync sales receipts with prefixes, manual entries follow that same sequence. 

For you to prevent the use of prefix for manual orders, you can manually override by creating 3–5 manual sales receipts in a row, entering the number format you want (e.g., "1001", "1002", "1003"). This resets the sticky sequence for manual entries.

 For this to happen, make sure that Custom transaction number is turned on.

Here's how:

1. Go to the gear icon.
2. Under Your Company, select Account and settings.
3. Click on Sales, and hit on Sales transaction number.
4. Switch it on by clicking on it if it is off.
