Single-carrier integrations

19 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.

• SellerDash: AusPost Shipping 673 reviews · 4.75★ · fair evidence

  A dependable, well-supported way to print Australia Post MyPost Business labels from Shopify, but pricing is the sore point and orders with multiple parcels need workarounds.

  Most common complaint: Cost: monthly fee plus per-label or transaction charges, seen as expensive and unclear at volume (7 reviews, rising).

• Post & DHL Shipping (official) 287 reviews · 4.63★ · solid evidence

  If you ship from Germany on your own DHL business contract, this free app does the job and its support team fixes almost anything within hours, but setup is fiddly and you won't see what each label costs.

  Most common complaint: Hard to set up and use: the interface isn't intuitive, settings are hidden, and label creation sits under Shopify's 'More actions' menu rather than inside the app (25 reviews, steady).

• DHL & Post Shipping | easyDHL 384 reviews · 4.88★ · fair evidence

  A well-liked German DHL/Deutsche Post label and invoice tool with quick, personal support, but the paid tiers got more expensive in 2025 and a few reviewers report tickets going unanswered until they posted publicly.

  Most common complaint: Price and tier complaints: entry price seen as high, jumps between tiers, and the Premium+ tier is not clear in the listing (8 reviews, rising).

• Colissimo Official 231 reviews · 4.85★ · fair evidence

  The best-supported way to ship with Colissimo from Shopify, with very fast human support, but the subscription now scales with your Shopify plan and recent hikes have hit low-volume and pickup-point-only users hard.

  Most common complaint: Small missing features: saved filters, archiving, spreadsheet import, label cost display, return+outbound printing together, lettre suivie (5 reviews, fading).

• Zasilkovna • Packeta Pickup 86 reviews · 4.85★ · fair evidence

  If you ship Packeta/Zásilkovna from a Czech or Slovak store, this does the job and the support chat answers within minutes — expect a day or two of widget fiddling at setup, and note the developer has stopped replying to reviews since February 2026.

  Most common complaint: Pickup-point widget doesn't appear or misbehaves at setup; support has to unblock it (5 reviews, steady).

• All In One Australia Post Ship 133 reviews · 4.92★ · fair evidence

  A cheap, well-supported label-printing app for small Australian shops with an Australia Post Business account; almost uniformly praised, but little evidence on high volume or checkout rates.

  Most common complaint: Missing features requested by users: return labels, saved default settings, editable posting references (3 reviews, steady).

• PH Ship Rate & Track for FedEx 657 reviews · 4.92★ · fair evidence

  A capable FedEx-only app where the support team does most of your setup; the 5.0 rating mostly measures onboarding-call goodwill, and freight, multi-location and partial-fulfilment users get burned.

  Most common complaint: Setup is complex: many settings, boxes, zones, FedEx credentials. Most reviewers say they needed support to get it right. (14 reviews, steady).

• EZLabel: Australia Post Ship 858 reviews · 4.96★ · fair evidence

  A free-to-start, no-frills Australia Post label printer that small Australian stores find fast and simple; the near-perfect star rating is inflated by prompted new-install reviews, so trust the specifics, not the 4.96.

  Most common complaint: Connection / 'doesn't work' problems with the MyPost Business link or the app (mostly minor, one unexplained 1-star) (4 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).

• DPD Shipping | easyDPD 107 reviews · 4.47★ · 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).

• MyGLS Professional 140 reviews · 4.97★ · fair evidence

  If you ship with GLS in Hungary or nearby Central/Eastern European countries, this app prints your labels and adds a parcel-shop picker to your cart, and the developer usually sets it up for you within hours. Just know the 5-star rating mostly measures thanks for that setup help.

  Most common complaint: Occasional bugs and setup issues come up. All reported ones were fixed quickly (the named bugs are a parcel-shop geolocation glitch and the product name missing from the label). Other reviews just say problems were solved (9 reviews, steady).

• Mondial Relay Inpost Official 109 reviews · 4.29★ · 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).

• GLS Shipping | easyGLS 43 reviews · 4.77★ · 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).

• PluginHive Australia Post Ship 145 reviews · 4.9★ · fair evidence

  If you ship with Australia Post from an Australian store and want rates and labels inside Shopify, this works — but you are effectively buying a hands-on setup service, and the reviews almost all stop the day after that setup.

  Most common complaint: Setup is not self-serve: reviewers repeatedly need a call or the team to configure rules for them (8 reviews, steady).

• UPS Shipping (Official) 116 reviews · 4.79★ · fair evidence

  A free, UPS-only label dashboard that works well with your own UPS account and has very responsive support, but it won't show UPS rates at checkout and lacks some UPS services and advanced features.

  Most common complaint: Missing features or UPS services (Ground Saver/SurePost, split shipment, address validation, returns portal, sub-users, shipment receipt PDF, removing already-fulfilled orders) (9 reviews, steady).

• AMP Australia Post Shipping 142 reviews · 4.71★ · fair evidence

  A long-proven Australia Post rates-and-labels app for small Australian stores, but since the sale to AMP support has gone silent for weeks at a time, and the new team's turnaround is only about three months old.

  Most common complaint: Support slow or silent for weeks, no weekend or after-hours cover, often while checkout rates are broken (10 reviews, fading).

• Click & Drop 89 reviews · 1.72★ · solid evidence

  A free Royal Mail-only order importer that works until it silently stops importing, and most reviewers in the last year report exactly that, with slow or formulaic support.

  Most common complaint: Orders stop importing or the integration keeps disconnecting; shippers fall back to typing orders in by hand (38 reviews, rising).

• PostNord by Uniwin 59 reviews · 4.66★ · thin evidence

  It works once Uniwin configures it for you on a video call — budget for that call, because almost nobody in these reviews got it running alone.

  Most common complaint: Setup is not self-serve — shipping settings are confusing and several merchants could not get it working without a call from Uniwin (6 reviews, steady).

• PostNord by SYNKA+ 31 reviews · 4.61★ · thin evidence

  A Swedish PostNord connector that new users praise for hands-on onboarding, but most reviews are from the first days of use and the only long-term customers who wrote complain about slow, curt support.

  Most common complaint: Slow or curt support for long-term customers (2 reviews, rising).
