Fulfilment and 3PL
4 apps with enough reviews to judge, ordered by how their reviews hold up: recent complaints, praise from stores six months or more in, how the developer handles problems, not stars.
The coloured strip under each app shows who wrote its positive reviews: within a day of install, days, months, a year or more.

iPacky | Pick Pack & Fulfill 132 reviews · 4.94★ · fair evidence
If you pack orders in your own warehouse and want scanning to stop mispicks, this does it cheaply and the founder ships requested features in days — you just have to accept a dated interface and spend real time on setup.
Most common complaint: Dated, cluttered interface — settings spread out, admin/dashboard not Shopify-like (6 reviews, steady).
-
Order Fulfillment Guru 112 reviews · 4.95★ · fair evidence
A configurable order-routing and dropship app that reviewers love mainly for hands-on developer support, with a thin but real record of inventory-sync trouble and a high share of day-one reviews.
Most common complaint: Setup is complex for non-trivial cases (multi-store, freight mapping, supplier notifications) and needs back-and-forth (5 reviews, fading).
-
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 (3 reviews, steady).
-
LVK Logistics 90 reviews · 4.21★ · thin evidence
A US 3PL warehouse whose 2020–2021 reviews rave about onboarding and support, but whose 2022–2024 reviews describe late orders, lost inventory, overbilling and a $500/month fee, and much of the praise looks solicited.
Most common complaint: Late or stalled orders, missed SLA, orders needing a support case to get packed (14 reviews, fading).
