Late postbacks break reporting only when you treat them like bad traffic

A conversion that lands hours or days after the click is not automatically a loss. First, check whether the delay is normal for that offer, device, or traffic source. Some flows send the postback after approval, queueing, fraud review, or internal batching.

Build your reporting window around reality, not around the hour the click happened:
• keep a raw click log with click ID, source, offer, and timestamp
• compare conversions by click date and by conversion date
• separate “pending” from “missing” until the attribution window closes

When a postback is late, the main risk is double counting or premature optimization. If you judge a campaign too early, you may pause a source that is actually converting, just slower than your dashboard. If you reconcile numbers, use the network’s accepted conversion timestamp, not your own guess.

A simple rule helps: if delays are consistent, treat them as part of the funnel; if delays are random, inspect the tracking path for lost click IDs, broken redirects, redirect caching, or partner-side processing gaps.

Keep one habit: review performance only after the full attribution window, then decide. Fast conclusions are the most expensive tracking mistake.
