Usage-based pricing
Usage-based pricing is a model where the cost of software scales with how much it is actually used, rather than sitting at a flat monthly fee. In virtual try-on apps it usually takes the form of credits: each generated image or video draws down a monthly allowance included with the plan, with a per-credit price for anything beyond it. The model exists because every AI render carries a real compute cost for the vendor.
Why AI try-on apps meter usage
Most Shopify app features cost the vendor almost nothing per use, so flat monthly pricing works. AI try-on is different: every render runs a model on the vendor’s servers, and a store whose shoppers generate thousands of try-ons costs far more to serve than a quiet one. Metering passes that cost through in proportion to activity. The upside is a bill that tracks genuine shopper engagement; the downside is that usage needs watching, because an allowance can run out mid-month.
The typical structure
The common shape is a monthly subscription that includes an allowance, a per-unit price for anything beyond it, and better rates on higher tiers. Looksy follows it: Starter, Growth and Scale include 100, 300 and 600 monthly credits, additional credits fall from $0.14 to $0.10 as the tier rises, and Scale credits can be spent on photo or video try-ons. The Free plan works differently — unlimited try-ons with Looksy branding, capped by additional revenue rather than by credits.
What to compare between plans
Usage-based plans differ in details that matter more than the headline allowance. Establish what consumes a unit — whether a retry with a new photo spends another, and whether failed generations count. Check whether unused allowance rolls over, what the overage rate is, and whether video draws from the same pool as photos. A plan that looks generous on paper can behave differently once real shopper behaviour, with its retries and abandoned sessions, meets it.
