Tacey

Tacey is a Shopify app for post-purchase order editing and address validation. Customers can correct shipping addresses, change quantities, swap variants, add items or cancel eligible orders from the thank you and order status pages. Merchants can set edit windows, hold fulfillment while changes are allowed, and merge two paid orders from the same customer into one shipment. Tacey also provides pre-shipment reminders, post-purchase upsells, PDF invoices and a record of order edits and refunds. Paid, from US$29/month, with a 14-day free trial.
