EZLabel: Australia Post Ship 840 reviews · 4.97★ · fair evidence
If you're a small Australian store shipping only with Australia Post through MyPost Business, this is a cheap or free way to stop copying orders into AusPost by hand. Just know that printing a label also fulfils the order and emails the customer.
Most common complaint: Clunky screens: too many clicks per label, sideways scrolling, pages too wide (4 reviews, fading).
-
SellerDash: AusPost Shipping 665 reviews · 4.74★ · fair evidence
If you ship with Australia Post MyPost Business, it stops you copy-pasting addresses and gets you fast local support, but check the per-label fees and know that each order ships as one parcel.
Most common complaint: Too expensive: monthly fee plus per-label charges above the free allowance (8 reviews, rising).
-
PH Ship Rate & Track for FedEx 638 reviews · 4.92★ · fair evidence
It exists because Shopify's native carrier setup won't give you FedEx One Rate or your negotiated FedEx rates without the Advanced plan — it fills that hole well for parcel, leans hard on a human onboarding call, and is weakest on FedEx Freight/LTL.
Most common complaint: Setup is genuinely complicated and effectively requires a support call to finish (25 reviews, steady).
-
DHL & Post Shipping | easyDHL 382 reviews · 4.87★ · fair evidence
If you ship from Germany on your own DHL business account and Deutsche Post, this replaces DHL's own tools well — but budget roughly €20–25/month, and expect ticket-only support that a minority of merchants say they only reached after posting a public review.
Most common complaint: Price and plan changes: merchants report features they used for free moving behind a paid tier, and find the entry price steep for what they use (11 reviews, rising).
-
Post & DHL Shipping (official) 286 reviews · 4.64★ · fair evidence
Free official DHL label printer that does the job for German shops once it is configured — but setup is fiddly, it shows you no shipping prices anywhere, and what most reviewers are actually rating is the support team.
Most common complaint: Setup and UI are not self-explanatory — settings are buried, error messages unclear, most reviewers needed support to finish the install (24 reviews, steady).
-
Colissimo Official 225 reviews · 4.88★ · fair evidence
If you ship with Colissimo from France, this is the app people stay on Colissimo for — a small French team answers in minutes and ships fixes in hours — but it is a pass-through to La Poste's web services, so when those break your labels stop and nobody can help you.
Most common complaint: Missing workflow conveniences: filters cannot be saved and orders cannot be archived; no Excel bulk upload to print a list of orders; no Lettre Suivie support; cannot print outbound and return slips together; insurance is ad valorem only; Colissimo price not shown on the label-creation screen (5 reviews, fading).
-
PluginHive Australia Post Ship 142 reviews · 4.9★ · fair evidence
A solid Australia Post-only rates-and-labels app whose reviews are overwhelmingly about the onboarding phone call, not about running it at volume — plan on a support session to get it configured, and don't expect it to be self-serve.
Most common complaint: Not self-serve: configuration is complex enough that most reviewers only succeeded with a guided call. Visible inside 5-star reviews, not filed as complaints. (25 reviews, steady).
-
MyGLS Professional 137 reviews · 5.0★ · thin evidence
If you ship GLS in Hungary or nearby CEE countries this does the job and the developer will personally configure it for you — but the 5.0 rating measures that onboarding, not years of running the app at volume.
Most common complaint: Not self-serve: the developer configures the store for you, and the choice between GLS integration routes is unclear on your own (35 reviews, steady).
-
AMP Australia Post Shipping 137 reviews · 4.7★ · fair evidence
The deepest Australia Post integration on Shopify and a real time-saver once configured, but it changed owners, support went dark from roughly 2024 to mid-2026, and checkout rates can stop showing without warning — a new team only began fixing this around July 2026.
Most common complaint: Support went unresponsive after AMP took the app over — unanswered tickets for days to weeks, dead live chat; improving only since about July 2026 (9 reviews, fading).
-
All In One Australia Post Ship 129 reviews · 4.92★ · fair evidence
If you're a small Australian store printing AusPost labels off a desktop, this does the job cheaply and the developer actually answers chat — but the mobile interface, the free-label counter and some post-update screen behaviour are unfixed as of the newest reviews.
Most common complaint: Screen friction after an update: an extra step before printing, and packaging selection reverting off custom packaging instead of sticking (3 reviews, rising).
-
UPS Shipping (Official) 119 reviews · 4.8★ · fair evidence
If you ship UPS from Europe and already have a UPS account with negotiated rates, this replaces ups.com and saves real time — but it does not show rates at checkout, and the standout feature reviewers talk about is the support agent, not the software.
Most common complaint: Interface is hard to read and the workflow is not self-explanatory; UPS service names in the app confuse people (7 reviews, steady).
-
Mondial Relay Inpost Official 111 reviews · 4.31★ · fair evidence
If you sell in France and just need Mondial Relay relay points plus labels, this works and the French support team fixes setup fast — but order status sync into Shopify has been broken for multiple merchants since 2025, refunds are refused, and the developer has not replied to a single public review since October 2023.
Most common complaint: Price too high for a single-carrier app (35€–80€/month reported), and the checkout-extensibility version needs an extra Google subscription (8 reviews, steady).
-
DPD Shipping | easyDPD 105 reviews · 4.46★ · fair evidence
If you ship domestic German DPD parcels and want two-click bulk labels plus paperwork, this does the job well — but it dead-ends on customs and third-country shipments, and two merchants in the last year say support de-prioritised or blocked them after a bad review.
Most common complaint: Support goes unanswered, gives one-line brush-offs, or is described as out of its depth (5 reviews, steady).
-
Click & Drop 89 reviews · 1.72★ · solid evidence
Free and adequate when it runs, but the dominant 2025-26 report is that it quietly stops importing Shopify orders while still showing a green "connected" tick, and the usual fix is deleting and rebuilding the integration.
Most common complaint: Orders silently stop importing, or import only partially, while the integration still shows as connected (55 reviews, rising).
-
Zasilkovna • Packeta Pickup 84 reviews · 4.85★ · fair evidence
If you ship Packeta in CZ/SK it does the job and the support team is genuinely fast, but without Shopify Plus your customer only picks their pickup point after they have already paid — and no review confirms that has been fixed.
Most common complaint: Pickup-point map / widget fails to load or shows wrong data (wrong tariff, bad export to Packeta); always fixed by support, but it recurs across years (8 reviews, steady).
-
PostNord by Uniwin 58 reviews · 4.66★ · thin evidence
A PostNord Sweden/Denmark connector whose real product is a person who configures it for you on a video call — the reviews document the onboarding, not what the app does in month six.
Most common complaint: Setup is not self-service. Shipping settings are confusing and several merchants could not get the app running without a live session with support. (5 reviews, steady).
-
GLS Shipping | easyGLS 42 reviews · 4.76★ · fair evidence
A simple, reliable GLS label printer that German and Austrian shops keep using for years — but one recent detailed review says labels the app marked "cancelled" were still live at GLS and got invoiced, and the developer never replied to it.
Most common complaint: No bulk/batch customs clearance; developer acknowledges the request but cites technical restrictions (2 reviews, steady).
-
Swiss Post Label Printer 32 reviews · 4.91★ · fair evidence
If you're a Swiss store shipping with Swiss Post, this does one job — labels plus tracking write-back — and the support answers fast; it is not a multi-carrier tool and the review record is too thin to see how it fails.
Most common complaint: No full automation of label creation — you still trigger it per order (1 reviews, steady).
-
PostNord by SYNKA+ 30 reviews · 4.6★ · thin evidence
Swedish PostNord label printing that people love in week one and two long-term users rate 1★ over support — the reviews tell you almost nothing about what year two looks like.
Most common complaint: Support quality collapses for established customers: multi-week reply gaps, curt or dismissive tone, and being redirected to a help page that doesn't answer the question. Both reviewers on the app a year or more report this; neither disputes that the app itself works. (2 reviews, rising).
