A clear returns and credit process on Diamond Pro protects the relationship when something goes wrong.
Buyers who treat returns and credit notes as a commercial discipline rather than an afterthought tend to hold margin for longer.
Seasonality interacts with returns and credit notes more than most forecasts allow for, so a rolling review beats an annual one.
Why returns and credit notes matters on the Diamond Pro
Distinguish between a defect claim and a change of mind before agreeing any action.
A written internal standard for returns and credit notes makes onboarding new account managers far quicker and reduces avoidable errors.
Credit notes should reference the original invoice line to keep accounting clean.
