Trace the source
Keep quote and invoice rows beside the calculation. A number without provenance is only a hunch.

Find the difference.
Follow the credit to its receipt.
An invoice difference is not recovered money. See how a supplier promise becomes a verified credit only when later evidence arrives.

THE DISTINCTION THAT MATTERS
Separate the states
Potential difference, supplier promise and observed credit are different events. None stands in for another.
Close only what cleared
A partial credit reduces the outstanding amount; the remaining balance stays visible for follow-up.

to USD 20.00 evidenced.
