What is post-purchase feedback?
Post-purchase feedback is what a customer tells you after they receive, use, or experience a product - not what they say at checkout, and not yet the same thing as the signal it eventually becomes.
The problem
A response isn't the same thing as an answer.
Most brands collect some form of post-transaction feedback already - a post-delivery form, a support inbox, a handful of reviews. What's usually missing isn't the feedback itself. It's what happens to it after it arrives.
A spreadsheet of open-text replies, read one at a time, doesn't scale into a decision. A single satisfaction score doesn't say which product it's about. Collecting customer feedback after purchase is the easy part - the harder, more valuable part is turning it into something a product or retention team can act on.
The definition
What is post-purchase feedback?
Post-purchase feedback - also called post-transaction feedback - is what a customer says about a product after they've received, used, or experienced it: whether it worked, whether it arrived in good condition, whether they'd buy it again. It's collected after the sale is already made, which is what separates it from a checkout survey that only measures purchase intent.
Purchase and delivery aren't the same moment. Feedback gathered right after purchase mostly reflects the buying decision the customer just made. Customer feedback after delivery reflects the product itself, once there's actually been time to use it. That distinction is why a delivery-timed request, not a checkout prompt, is what captures product feedback after purchase that's worth reading.
Product feedback collection
How brands collect product feedback after purchase
Delivery-timed survey link
The brand sends a survey link in a delivery-timed email campaign, tied to the order identifier, usually 24-48 hours after the product arrives. This is the most common product feedback collection method for Shopify brands, and it's still just a mechanism - a survey is one way to capture a signal, not the definition of the feedback itself.
QR code or product link
For products bought outside Shopify - retail, CPG, subscription boxes - a QR code or embeddable link printed on packaging opens the same feedback channel, without needing a store connection or order data. It's an open channel anyone who scans or clicks can respond to, not a 1:1 order-verified response.
Reviews and support tickets
Both generate real feedback, but only from customers motivated enough to write one - usually at either extreme of satisfaction. They're valuable, self-selected sources, not a substitute for asking every buyer the same thing.
Quality, not just quantity
What good post-purchase feedback looks like
More responses isn't the goal. Feedback that's timed right, tied to a specific product, and verified against a real order is what's actually worth reading.

The bridge
From feedback to signal.
Feedback is a signal. Intelligence comes from understanding it. One response tells you what one customer thought. The same response, connected to the product it's about and aggregated against every other response for that SKU, tells you something a single reply never could: whether this is one customer's opinion, or a pattern worth acting on.
TrueSignal, Agaya Cloud's post-purchase intelligence product, treats feedback as one input among several - alongside usage, delivery friction, and reorder behaviour - and aggregates it by product so a real pattern becomes visible.

Post-purchase feedback, answered
What is post-purchase feedback?
Post-purchase feedback is what a customer says about a product after they've received, used, or experienced it - whether it worked, whether it arrived intact, whether they'd buy it again. Post-transaction feedback and customer feedback after purchase describe the same thing; all three sit downstream of the sale, not at checkout.
What's the difference between post-purchase feedback and a post-purchase survey?
A survey is one mechanism for collecting feedback - a specific set of questions sent to a customer. Feedback is the substance: what the customer actually says, however it gets captured (survey, QR code, support message, review). TrueSignal happens to use a delivery-timed survey link, but the feedback itself, not the form, is what matters.
Is customer feedback after purchase the same as customer feedback after delivery?
Close, but not identical. Purchase happens at checkout; delivery happens days later, once the product has actually arrived. Feedback collected right after purchase mostly reflects the buying decision. Feedback collected after delivery reflects the product itself - which is why a delivery-timed request, not a checkout survey, is what actually measures product experience.
What counts as product feedback collection, beyond a survey response?
Anything that captures a customer's experience with a specific product: a written response, a rating, a QR code scan tied to a SKU, or a support message about that item. Product feedback collection is broader than one channel - the goal is a structured record per product, not just whichever channel happened to generate a reply.
Is post-purchase feedback the same thing as a post-purchase signal?
Not quite. Feedback is an input - one customer's answer, at one moment. A signal is what that feedback, and other evidence like usage or delivery friction, reveals once it's connected to the product, the order, and the pattern across other customers. Feedback becomes useful at scale once it turns into a signal you can act on - see what a post-purchase signal is.
Does post-purchase feedback replace reviews or NPS?
No - they answer different questions. Reviews are public and self-selected. NPS is one brand-wide score. Post-purchase feedback, collected consistently after every order, reaches the quiet majority who'd never post a review, and reports it product by product instead of as a single company-wide number.
How does TrueSignal turn product experience feedback into something actionable?
TrueSignal ties every response to the order and SKU it came from, times the request to the 24-48 hour post-delivery window, then aggregates responses by product so a pattern is visible - not just individual replies. That aggregation is the step that turns feedback into a signal, and a signal into intelligence.
