Returns and exchanges

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.

PostCo Returns & Exchanges 101 reviews · 4.9★ · fair evidence

A rules-deep returns portal whose real product is the support team — excellent for AU/UK fashion and jewellery brands doing size exchanges, as long as you accept an annual contract, paid add-ons and a proper onboarding call.

Most common complaint: Setup is fiddly and effectively requires a guided onboarding; branding the portal and emails takes time (minority note — most reviewers call setup easy) (3 reviews, fading).
Return Prime:Return & Exchange 774 reviews · 4.9★ · fair evidence

Strong value and unusually hands-on setup help for returns and exchanges, but 2026 reviews report slow or absent support, automation and label faults, and almost half the praise comes from stores only hours or days in.

Most common complaint: Support slow, silent or no-show, at odds with the praise elsewhere (missed scheduled calls, unanswered tickets, a 48+ hour wait, an issue open over a month) (9 reviews, rising).
Yanet Returns & Exchanges 274 reviews · 4.85★ · fair evidence

A free returns-and-exchanges portal that small stores get running quickly thanks to a very responsive chat team, but return emails not arriving, no 3PL or courier support, and customisation that depends on support are real weak spots.

Most common complaint: Support is fast on setup questions but stalls, refuses or goes quiet on bugs, integrations and custom requests (7 reviews, steady).
Synctrack Returns & Exchanges 130 reviews · 4.88★ · fair evidence

A free returns and exchanges portal whose support team will customise it for you, but no reviewer confirms courier or return-label support, and most reviews were written in the first hours after install.

Most common complaint: Bugs and errors, mostly during onboarding. Usually fixed by support, except one store that said nothing worked (5 reviews, fading).
