Tacey

Tacey lets Shopify customers fix their own orders on the thank you page: correcting addresses with built-in validation, changing items or quantities, and cancelling without contacting support. Every edit is recorded, and duplicate orders can merge into one shipment. Built-in post-purchase upsells help merchants sell more before the order ships. For Shopify brands that want fewer support tickets and more post-purchase revenue. Paid, from US$29/month, with a 14-day free trial.
