Fulfilment and 3PL

4 apps with enough reviews to judge, by review count.

iPacky | Pick Pack & Fulfill 131 reviews · 4.94★ · fair evidence

If you pack your own orders and keep shipping the wrong items, this stops that cheaply and the founder will build what you ask for — but expect a plain interface, a few hours of setup, and uninstall it if you are only trialling, because the monthly fee starts once your store passes 50 orders a month whether you use the app or not.

Most common complaint: Setup takes real configuration effort; the number of settings overwhelms people at first (5 reviews, steady).
Order Fulfillment Guru 113 reviews · 4.95★ · fair evidence

If you need orders split and pushed to multiple warehouses, suppliers or partner Shopify stores, it does that and the team will configure it with you on a call — but plan for a real setup project and verify inventory sync yourself before you trust it.

Most common complaint: Setup is a configuration project, not an install — several reviewers needed a call, and freight/rate mapping confuses people (5 reviews, steady).
LVK Logistics 90 reviews · 4.21★ · thin evidence

Reviewers loved the named support reps and hated the warehouse — and since the newest review is December 2024 under a different brand name, nobody can tell you how it runs today.

Most common complaint: Orders sitting unshipped for days to weeks, SLAs missed, receiving backlogs causing stockouts (14 reviews, steady).
Shipr for Amazon FBA / MCF 34 reviews · 4.38★ · fair evidence

Cheap, simple and genuinely good at FBA/MCF fulfilment when it runs, but reviewers from 2022, 2024 and as recently as March 2026 report the automation silently stopping or tracking not posting back, and you find out when customers complain.

Most common complaint: Auto-fulfilment silently stops, or the order ships but no tracking is written back to Shopify — merchant finds out when customers chase (4 reviews, steady).
