Commerce · Post-purchase

The seven moments after checkout, automated.

SabNode ships a complete post-purchase suite — confirmation, payment receipt, shipping updates, delivery NPS, review prompt, replenishment nudge and reorder upsell. Each step is a real WhatsApp flow, not a templated email, and writes back to orders, contacts and your reviews tool.

  • Order, shipped, delivered, reviewed
  • Replenishment timed to product life
  • NPS and CSAT inside WhatsApp
  • Loops back into reorder upsell
The problem

Post-purchase is where loyalty is built or burnt

Most stores treat post-purchase as a single confirmation email and call it a day. That is the cheapest mistake in D2C. The seven days after delivery are when the customer is most likely to leave a review, refer a friend or buy again — and the silence from the brand during that window is what kills 70% of the LTV that should otherwise compound.

Doing post-purchase right with email alone is brutal: open rates fall below 18%, transactional emails get marked promotional, and review collection rates hover around 1-3%. WhatsApp inverts every one of those numbers, but only if the flow is structured correctly — order confirmation as a utility template, shipping updates as utility, review prompt as marketing with opt-in, and reorder upsell with the right delay tied to the actual product life.

SabNode ships all seven moments pre-wired. You connect Shopify and Shiprocket, install the post-purchase pack, and within five minutes every order that lands triggers the same journey that the best D2C brands build over six months. Each step is editable, each is attributed, and each rolls back into your dashboards as a revenue source.

What it is

Post-purchase Flows, in depth.

The Post-purchase pack is a set of seven installable flows that cover the entire journey from "order placed" to "customer reorders". Order confirmation fires within seconds of the Shopify order webhook, payment receipt fires when the gateway captures, shipped notification fires on Shiprocket's manifested event, and out-for-delivery and delivered events stream in from the carrier. Every message is Meta-template compliant, opt-in aware and personalised with order ID, AWB, ETA and product list.

Two days after delivery, the NPS flow asks "how likely are you to recommend us on a scale of 0-10?". Detractors are routed to a human agent for save-the-customer outreach. Promoters get a review request three days later with a direct link to your Yotpo, Judge.me, Loox or Google Business profile. The review collection rate consistently beats email by 4-6×.

Reorder is the loop. Each product can have a configured "reorder cycle" — 30 days for protein, 45 days for skincare, 90 days for cosmetics. At the right offset, the customer receives a personalised WhatsApp message: "your last cycle is wrapping up, want us to ship the same?" with a pre-filled cart and a one-tap UPI link. Replenishment alone routinely contributes 20-35% of total revenue for consumables brands.

Every step writes a sub-event on the order timeline, every reply is a conversation an agent can pick up, and every conversion attributes back to the post-purchase flow in dashboards. The pack runs out of the box, but the flow builder lets you fork any step with your own logic.

Capabilities

Everything you get with Post-purchase Flows.

7 capabilities
01

Order confirmation

Fires within 5 seconds of the order webhook. Includes order ID, item list, total, payment method and an expected delivery range computed from your Shiprocket SLA history.

02

Live shipping updates

Carrier events from Shiprocket, Delhivery, Bluedart and ShipStation flow into the timeline and trigger a WhatsApp utility template. Customers know exactly where their package is without opening a tracker page.

03

Delivery NPS

Two days after delivery the customer is asked a 0-10 question. Detractors route to an agent, promoters route to review collection. The flow is a clean conditional branch in the flow builder.

04

Review collection

Promoters get a Yotpo, Judge.me, Loox or Google review link three days post-delivery. Review collection rate runs 4-6× the email baseline, because the ask happens at peak emotional recall.

05

Replenishment timing

Each SKU can have a configured reorder cycle in days. The flow fires at cycle-end with a pre-built cart, discount code (if any) and one-tap UPI payment — no website redirect.

06

Refund/return flow

Customers can initiate a return inside WhatsApp. The flow collects reason, item, photo (via SabFiles), validates against return policy and creates the Shiprocket return label.

07

Loyalty signals

Repeat buyers, frequent reviewers and high NPS scorers get tagged automatically. These tags feed VIP broadcasts, early-access drops and loyalty pricing tiers.

Use cases

Built for the way teams actually work.

D2C
Case 01

Skincare replenishment

A skincare brand with 45-day cycle products sees 31% of customers reorder via the replenishment flow alone. The flow knows the last SKU, applies a loyalty discount and accepts UPI payment inline.

D2C
Case 02

Apparel review engine

A fashion brand 12×'s its review velocity by routing post-NPS promoters to a Judge.me link inside WhatsApp. The store's storefront review widgets fill out within a week, lifting product page conversion 8%.

E-commerce
Case 03

Returns containment

An electronics store funnels return requests through a WhatsApp flow that captures reason and photo. 25% of returns are deflected when the agent offers a swap, a how-to video or a partial refund credit.

Healthcare
Case 04

Healthcare follow-up

A diagnostics chain runs a post-test follow-up four days after the report is delivered. The flow asks if the patient consulted a doctor, offers a tele-consult slot via Razorpay, and improves consult attach 18%.

EdTech
Case 05

EdTech onboarding

After course purchase, the post-purchase flow walks the learner through Day 1, Day 7 and Day 30 milestones. NPS at Day 30 feeds into the upsell flow that pitches the next course in the ladder.

Frequently asked

Questions about Post-purchase Flows.

Can't find what you're looking for? Talk to our team.

Do I have to install all seven flows?
No. The pack is modular. Most merchants start with confirmation, shipping updates and review collection, then add NPS and replenishment when they are ready. Each flow has its own toggle and analytics view in the SabNode dashboard.
How do you set the reorder cycle per product?
You can set a default reorder cycle at the category level (skincare 45 days, supplements 30 days, cosmetics 90 days), then override per SKU. The cycle is editable in the catalog screen, and AI Studio can suggest a starting cycle based on your historical reorder gap data.
What if Meta classifies my review prompt as marketing?
It is marketing — and that is correct. SabNode only sends the review prompt to contacts who have a marketing opt-in. The NPS step doubles as the implicit opt-in checkpoint: customers who reply with a number have engaged with the brand post-purchase and can receive the next promotional ask.
Does the shipping update message double-send if I also use Shiprocket's own SMS?
Yes, that is on you to deduplicate. The common fix is to disable Shiprocket's SMS notifications for the channels SabNode is handling and let WhatsApp own the customer touchpoint. SabNode's flow has finer control over copy, timing and branding.
Can the NPS detractor branch route to a specific agent?
Yes. The flow builder lets you route detractors by team, by language, by AOV or by any contact field. A common setup is to route ₹5000+ AOV detractors to a senior CX agent and the rest to the regular queue.
How is review submission verified?
For Yotpo, Judge.me and Loox we listen for the review-submitted webhook and post a "thanks for reviewing — here is 10% off your next order" message. The reviewer is automatically tagged as a vocal-promoter and added to the early-access segment.
Will the replenishment flow stop if the customer reorders elsewhere?
Yes. If a new order comes in for the same SKU before the cycle fires, the existing replenishment job is cancelled and a new cycle is scheduled from the new order date. Customers never get a "time to reorder" message right after they already reordered.
