Your usage-based model sounds great until we hit a spike month and get a surprise invoice.

"We cap overage charges at 2x the base price — your invoice cannot balloon beyond that even in peak usage months. That cap is in the contract."

"Surprise invoices are the #1 reason customers leave usage-based tools. We built the cap specifically to prevent that — you know your worst-case month before you sign."

"What usage spikes are you worried about — seasonal peaks, campaign launches, something else? If I know the pattern, I can model a flat-rate floor that protects you from the spike without losing the usage model benefit."
