The Ecomm Analyst

Fairing (you might remember it as Enquire Labs) is the post-purchase survey tool a huge number of Shopify brands reach for first. It drops a short survey on the order status page right after checkout, and its Question Stream feature rotates different questions to different customers so you can build up a picture over time without nuking your response rate. The classic use is the how-did-you-hear-about-us question, which gives you a customer-reported read on attribution that no pixel can match. Pricing starts around $49 a month and climbs with order volume toward $149 and up, there is a free tier for very small stores, and it is Shopify Plus certified. Response rates in the 40 to 80 percent range are normal, which is why the data is actually useful.

People go shopping when the price escalates faster than they expected at higher order volumes, when they want deeper survey logic or benchmarking, or when they would rather have surveys built into the attribution tool they already pay for instead of running a separate app. Here are five alternatives, including the case for not buying a standalone survey tool at all.

KnoCommerce

Kno is the head-to-head rival, and the comparison is genuinely close. It pushes harder on survey logic, conditional follow-ups, benchmarking against other brands in its network, and modeling responses as if you had a hundred percent response rate. Plans run about $119 a month for the Analyst tier and $299 for Pro, with a free option to start. If you want the most survey depth and you are Shopify-native, Kno is the strongest case against Fairing. The knock is that it is Shopify-only and the price steps up faster than Fairing’s entry tier.

Zigpoll

Zigpoll is the budget-friendly, flexible option. It does post-purchase surveys but also on-site and exit-intent surveys, so you can ask questions at more than one point in the journey. It is cheaper than the two category leaders and a sensible pick if you want decent survey coverage without paying for the heavier attribution-focused feature sets. You give up some of the polish and the benchmarking depth.

ThoughtMetric

If your main reason for running surveys is attribution, it is worth asking whether you want a standalone survey app at all. ThoughtMetric is a multi-touch attribution platform that includes post-purchase how-did-you-hear-about-us surveys as part of the package, then reconciles that self-reported signal against its pixel data, all for around $99 a month with every feature included. (Disclosure: ThoughtMetric is a tool I use and have a commercial relationship with, so weigh that accordingly.) The pitch is one tool instead of two, with the survey feeding directly into your channel attribution rather than living in a separate dashboard you have to cross-reference. If you want a dedicated survey product with the deepest question logic, a specialist like Fairing or Kno still wins on that axis. If the survey was only ever in service of attribution, bundling makes sense.

Grapevine

Grapevine is a customizable post-purchase survey app that tends to appeal to brands that want to shape the survey experience closely and are happy to talk to the vendor about pricing rather than picking a published tier. It is less of an attribution-marketing story and more of a flexible feedback tool. Reasonable if customization is your priority.

The free baseline

Before you pay for anything, know that the floor is not zero by accident. Shopify’s own checkout extensions support a post-purchase survey, and some analytics suites (Triple Whale, for instance) bundle a basic how-did-you-hear question at no extra charge. For a small store just starting to ask the question, the free option collects real data. You will outgrow it when you want targeting, logic, and clean reporting, but it is a legitimate place to start.

Picking between these

• If you want the deepest survey logic and benchmarking and you are on Shopify, compare Kno against Fairing directly.
• If you want flexible, cheaper, multi-surface surveys, Zigpoll.
• If the survey only exists to improve attribution, get it bundled through ThoughtMetric and skip the second app.
• If you want heavy customization, look at Grapevine.
• If you are tiny and just starting, use the free baseline and upgrade when it pinches.

One thing worth saying out loud about every tool on this list. A post-purchase survey is a signal, not the truth. Customers misremember, they credit the last thing they saw rather than the thing that actually moved them, and the exact wording of your question quietly decides whether you are measuring first touch or last touch (how-did-you-first-hear-about-us pulls discovery, what-made-you-buy-today pulls the closer). The brands that get value from these tools treat the survey as one input they triangulate against their pixel data and their platform numbers, not as a verdict. Pick whichever tool fits your budget and your appetite for survey depth. Then spend more energy on asking the right question than on which app you asked it in.
