Fairing vs knocommerce: both are purpose-built post-purchase survey platforms that integrate with Shopify, but they take different approaches. Fairing favors deep Shopify-native integrations and flexibility across touchpoints, while KnoCommerce aims for fast setup, templated flows, and turnkey action automations; pick Fairing if you need extensible data routed into Shopify order metafields and checkout blocks, pick KnoCommerce if you want a quick instrumented survey that you can push into Klaviyo and Postscript audiences this week.
Imagine you just closed a 1,200-order launch for a DTC skin-care SKU that sells as a replenishable 60-day product. Picture this: your returns tick up, some customers complain about scent, and your email flows are average. You want to ask buyers two things on the thank-you page: how they heard about you and whether they plan to repurchase, then use those answers to build a segment that triggers a targeted replenishment flow and a 30-day check-in. Which tool lets your small ops team do that by Friday, and which one gives you the data model you can query inside Shopify later? That practical choice is the core of fairing vs knocommerce.
How to read this comparison
- Criteria I use: Shopify integration depth, speed to ship, targeting and triggers, data destination and schema, analytics and testing, and operational tasks an ops team will own (tagging, flows, customer support routing).
- Assumption: you are running a Shopify store with Klaviyo or Postscript for email and SMS, and your near-term KPI is repeat purchase rate, not purely attribution accuracy.
Quick feature posture
- Fairing installs as a Shopify app and supports embedding question streams on thank-you pages, order status pages, landing pages, and POS, and it can sync responses into Shopify order metafields. (docs.fairing.co)
- KnoCommerce advertises rapid setup, many templates, and direct integrations to Klaviyo and Shopify, with built-in actions like issuing promo codes or adding segments based on responses. (knocommerce.com)

What this means for moving repeat purchase rate
- If your plan is to use survey answers to immediately trigger a replenishment sequence or an SMS coupon for likely one-time buyers, KnoCommerce gives a faster path to set that up and push respondents into Klaviyo or Postscript audiences. That means you can start reclaiming future orders within days. (knocommerce.com)
- If your plan is to persist customer intent answers on the order record, join them to SKU-level returns or support tickets, and run cohort analysis to change your product page copy or subscription offers, Fairing’s ability to write into Shopify order metafields and support multiple embedded surfaces is more valuable. (fairing.canny.io)
A few practical DTC scenarios
- Scenario A: You sell replenishable wellness supplements, AOV $55, and want to convert first-time buyers into subscription within 45 days. Action needed: ask “Would you like to receive a 20% discount to subscribe?” on the thank-you page, then add respondents to a Klaviyo flow that surfaces a product discount and subscription CTA. KnoCommerce gets you live quickly with built-in promo issuance and Klaviyo actions. (knocommerce.com)
- Scenario B: You sell small-batch apparel, AOV $88, and you want to diagnose sizing returns by SKU. Action needed: map “Was the size accurate?” answers into order metafields to run SKU-level return risk analysis and change product pages. Fairing’s mapping into Shopify order metafields is the better fit. (fairing.canny.io)
- Scenario C: You want both: light-touch launch now, richer data later. Ship with KnoCommerce templates to start reclaiming revenue, and plan a parallel Fairing implementation to capture schema-backed data into order metafields for long-term analytics.
People also ask
Which is better for Shopify post-purchase surveys, Fairing or KnoCommerce?
Answer: It depends on whether you prioritize speed to action or Shopify-native data control. Choose KnoCommerce for rapid templated surveys and built-in Klaviyo/Postscript automations, pick Fairing for richer integration into Shopify order metafields and multi-surface survey embedding. (knocommerce.com)
Can I run post-purchase surveys on the Shopify thank-you page?
Answer: Yes, both platforms support thank-you page or order status page deployments; Fairing documents Checkout Extensibility and blocks for thank-you pages, and KnoCommerce offers one-click Shopify integration with templates for checkout touchpoints. Test in a staging order before shipping. (docs.fairing.co)
Will post-purchase surveys increase repeat purchase rate?
Answer: Surveys themselves are not a guaranteed lever, but post-purchase engagement and targeted follow-ups often raise repeat rates when tied to action flows; examples exist where post-delivery check-ins or lifecycle flow improvements produced large lifts in repeat purchases. Use the survey to segment and trigger flows rather than expecting the survey alone to change buyer behavior. (returnsignals.com)
Implementation checklist an ops person can run this week
- Define the action you want from the survey. Examples: add to Klaviyo replenishment flow, tag order for follow-up by support, or trigger a timed SMS. Keep it to one primary action to measure impact.
- Pick the touchpoint you control: Shopify thank-you page if you are on an extensible checkout, or a post-purchase email/SMS link if you are not. Testing both increases capture. (docs.fairing.co)
- Build a minimal survey: 3 questions max. Example: where did you first hear about us, what prompted this purchase, do you plan to repurchase or subscribe? Map responses to a single destination: a Klaviyo property or a Shopify order metafield.
- Run a 50/50 experiment for 90 days. Measure repeat purchase rate at 60 and 90 days for respondents vs non-respondents; attribute lifts back to the triggered flows, not just the survey. Good experiments show whether surveys + follow-ups change behavior.
Real numbers, and why you should care
- A DTC brand that added a post-delivery conversational check-in saw a 51 percent higher repeat purchase rate in the treatment group compared to the control group when customers engaged with the check-in. That illustrates how post-purchase contact, not necessarily the survey itself, can drive repurchase behavior. (returnsignals.com)
- Another DTC brand that revamped lifecycle and post-purchase flows reported a 20.6 percent improvement in repeat purchase rate after improving engagement and follow-up routines. Use cases like these show the impact of acting on the survey results, not just collecting them. (convertcart.com)
Limitations and caveats
- You need a minimum volume to measure lift reliably. If you process fewer than 300 post-purchase survey exposures a month, your 90-day repeat rate comparisons will be noisy. Plan longer tests or pool cohorts.
- Surveys often capture post-intent bias; customers on the thank-you page have just purchased and answer differently than they will later. Use follow-up touchpoints to validate intent signals before adding discounts or long-term segmentation.
- Both tools may require Plus-level Shopify access to fully edit checkout blocks depending on your checkout setup; confirm your store’s extensibility options before selecting a commit path. (docs.fairing.co)
Decision guide: which to pick this week
- If you must ship a replenishment or coupon-triggered flow now and want a low-friction setup that plugs into Klaviyo or Postscript, pick KnoCommerce and get a templated survey live in a day. (knocommerce.com)
- If you want durable data that you can join to orders, returns, and customer lifetime value inside Shopify and use in Shopify Flow or your analytics warehouse, pick Fairing and plan a two-week rollout to map fields and test. (fairing.canny.io)
- If you want both speed and structure, start with KnoCommerce to get immediate actions running, and run a parallel Fairing plan to capture canonical responses into Shopify order metafields for long-term cohort analytics.
Operational tasks to measure ROI on repeat purchase rate
- Instrument an experiment: create respondent and non-respondent cohorts, send the same follow-up experiences only to respondents, and measure D30, D60, and D90 repeat purchase rate.
- Track which survey answers correlate to early churn or high repurchase, then automate flows: e.g., “no plan to repurchase” → add to an educational sequence; “sizing issue” → automated return/handoff to support plus a targeted fit guide.
- Use answers to seed lookalike audiences for LTA acquisition channels only after you have validated respondent behavior over a 90-day window.

How Zigpoll handles this for Shopify merchants
Trigger: Use Zigpoll’s post-purchase thank-you page trigger to display the short survey immediately after order confirmation, and pair it with an email follow-up link for customers who don’t complete the on-site survey. For subscription cancellation use cases, use the subscription cancellation trigger; for in-person events, use the POS or on-site widget on the order status template. This dual-trigger approach increases capture while keeping the initial survey brief.
Question types and wording: Start with three questions. (a) Multiple choice attribution: "Where did you first hear about us? (Paid social, Organic search, Friend/Referral, Other)". (b) Yes/No + branching intent: "Do you plan to buy this product again? Yes / No" If No, follow with (c) free text: "What would make you buy again from us?" Optionally add a 0 to 10 star intent question for quick scoring.
Where the data flows: Push Zigpoll responses into Klaviyo as customer properties and into Klaviyo segments to trigger replenishment or win-back flows, and write the same responses to Shopify order metafields or tags so your CS and analytics teams can join survey answers to SKU returns or support tickets. Also route alerting responses (for example, "Size issue") to a Slack channel for immediate support triage and to the Zigpoll dashboard for segmentation by cohort.
