A single customer journey can trigger dozens of billable events across filters, paths, lookups, and formatters. If each branch counts, a small spike becomes a real bill. Measure with instrumented test runs and dashboards. Ask whether polling checks are billed. Confirm whether failed steps count. Know if scheduled scans for changes bill even when nothing changed. Trim wasted steps by consolidating logic and using native app filters first.
Microbusinesses often run flash sales or holiday campaigns that multiply traffic. Ensure plans can scale temporarily without expensive jumps or throttling that breaks checkout. Webhooks reduce polling costs; batching reduces event storms. Create temporary flows for promotions and disable them after. Add alerts tied to usage thresholds to avoid surprises. One artisan candle brand avoided overage fees by switching a busy email parser to webhook delivery before launch weekend.
