One Click Upsell ‑ Zipify OCU

Two days in and nothing has worked as promised.

Setup: The pre-purchase upsell and cross-sell offers never showed. I opened a support ticket right away and explained that I use an alternative payment processor and that the pre-purchase upsell wasn’t appearing.

Support response: I gave the team store access immediately, but it still took a full day before their developers started on it, plus a lot of back-and-forth with support. They then told me everything was fixed and working.

After the “fix”: I activated the funnel, and it began doubling product quantities as soon as customers clicked “Start Checkout.” My conversion rate dropped sharply as a result. I should have tested it myself before going live, but a dev team making changes this sensitive to someone’s checkout should verify their work before calling it done.

In all my years on Shopify, this is the worst app experience I’ve had. If you use a non-native Shopify payment processor, test thoroughly or look elsewhere.
