Optimizing Checkout for Credit-Based AI Labs
Players tolerate friction when the joke lands, not when they e trying to buy credits. These tweaks helped us keep Stripe Checkout fast, transparent, and high-converting.
Visualize value before the paywall
We preview the new balance on hover ( op up to 25 credits ? so buyers do the math without leaving the lab. The preview includes the expected number of runs based on current burn rate. When people understand what they e buying, they breeze through checkout.
Keep pack names consistent with Stripe
Each pack uses the same label everywhere: pricing page, modal, email receipt, and Stripe dashboard. That means no internal shorthand like ack A. ?Consistency reduces refund confusion and simplifies support audits.
Prefill email and client context
When a logged-in player hits checkout we pass their email (if shared) plus client_id metadata to Stripe. Webhooks replay that metadata so our credit store knows exactly which device to refill when the payment clears. No manual mapping, no lost credits.
Explain taxes, refunds, and timing
Checkout descriptions include redits deliver instantly. No expiry. Refunds: support@aiviraltestlab.com. ?Transparency builds trust, especially for $1.99 impulse buys. We also link to Support Contact in the pricing FAQ and receipts.
Instrument the drop-off points
We log each step: modal open, pack selection, Stripe session created, session completed, credits granted. When we see abnormal drop-off (e.g., a region failing 3D Secure), we can respond before Twitter does. All events reference the pack ID, so growth can AB test copy without bugging engineering.
Mitigate fraud without punishing fans
Stripe Radar handles most risk, but we add soft limits: if a client redeems more than 200 credits in an hour, we flag the account for review. Flags pause new runs but leave existing credits untouched while support investigates.
Localize payment messages
When we launch in a new region, we adjust currency symbols, billing descriptors, and VAT text. Fans hate seeing USD if they e paying in GBP. Stripe multi-currency settings plus our copy overrides keep everything aligned.
