A clear returns and credit process on Zen Pro protects the relationship when something goes wrong.
The Zen Pro has settled into a stable position in the range, which makes returns and credit notes the natural next question for distributors.
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 Zen Pro
Distinguish between a defect claim and a change of mind before agreeing any action.
Where two suppliers look identical on price, returns and credit notes is usually the variable that separates them over a full year.
Credit notes should reference the original invoice line to keep accounting clean.

Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.
