Definition
A post-purchase flow is an automated sequence triggered after a purchase — with an order confirmation, product onboarding and a nudge toward the next order.
Also called: Post-purchase flow, After-purchase flow, Post purchase
Sådan virker det
Post-purchase-flowet møder kunden lige efter købet: bekræftelse, onboarding af produktet og et skub mod næste ordre. Det forkorter payback ved at fremrykke andet køb — og reducerer returer og supporttryk gennem god forventningsafstemning.
01Retention's underrated engine
Most brands stop paying attention at the order confirmation. But it's right after the purchase that retention is won or lost. The post-purchase flow onboards the product (so the customer gets the value and avoids returns), strengthens the relationship, and pulls the second purchase forward — which directly shortens the payback period.
It's also a calm place to ask for the things that build future growth: reviews, user-generated content, an SMS opt-in. Because the customer just had a good experience, willingness is high — and each of those feeds the rest of the machine.
Frequently asked questions
Why is the post-purchase flow important?+
Because retention is decided after the purchase. The flow onboards the product, reduces returns, pulls the second purchase forward (shortening payback) and collects reviews and UGC. It's one of the cheapest ways to lift CLTV.
What should a post-purchase flow include?+
Order confirmation and expectation-setting, product onboarding, a prompt for a review or UGC, and a well-timed nudge toward the next purchase (cross-sell or replenishment). Tone is service first, sale second.
