Split-test the merchant account, not just the page
Documentation
You ran two merchant accounts and had a hunch that one approved more cards than the other. Proving it meant exporting settlement reports and squinting at a spreadsheet a week too late.
The enemy is guessing which MID to route the next sale through.
Checkout now split-tests at the merchant level. Point a product at more than one MID and ElasticFunnels rotates live traffic across them, measures the approval rate for each, and shows the results side by side, exactly like a page split test. Send more volume to the account that actually approves.
Every charge is idempotent and rebills are guarded, so a retry never double-charges a customer and a routing change never breaks an existing subscription.
Try it: attach a second MID to a live product, send test traffic, and watch per-MID approval rates fill in on the checkout report.
