Monitoring is not the same as matching
A monitor should answer what changed, where it changed, and whether the offer is comparable. A repricing action should only happen after margin guardrails and approval logic have passed.
This separation keeps pricing teams from treating every scraped competitor price as an instruction.
What a useful monitoring workflow stores
A useful workflow records product identity, competitor URL, observed price, timestamp, evidence, and whether a recommendation would remain above the merchant's target margin.
That evidence lets a merchant review patterns instead of reacting to one-off price drops.
When to calculate before repricing
Calculate before approving any match that is close to margin floor, based on a new competitor, attached to a promotion, or different from normal market price.
