Hi Nasir.Mushtaq997,

I agree with your idea when it comes to entering the 7th decimal number at the exchange rate.

I consider that this is a valuable product add-on feature and that this could really help us improve the customer experience for QuickBooks Online.

This has been appraised and I have included my proposals for it. It would be excellent if you can also submit a feedback for this one through the Gear icon then the Feedback link.

As QuickBooks Online FX rate source is Wall Street Journal  which has 4-5 decimal places, QBO defaults/only have a limit of the decimal digit.

The recommended workaround is you can either round to the nearest or only use the max digits.

If you have further questions please let me know.
