Should I send product restock notifications?

As an e-commerce store owner, I'm struggling with managing customer expectations when products go out of stock. I want to improve customer experience and potentially recover lost sales, but I'm unsure about the best approach to product restock notifications. How can I effectively implement a system that keeps customers informed and potentially drives additional sales when items become available again?

TL;DR - Quick Answer

The most important e-commerce KPIs to track are: conversion rate, average order value (AOV), customer acquisition cost (CAC), customer lifetime value (LTV), LTV:CAC ratio (target 3:1+), and cart abandonment rate. These six metrics tell you whether your business is growing profitably.

What E-Commerce KPIs Should I Track?

Most stores track too many metrics or the wrong ones. Vanity metrics like total page views, social media followers, and traffic look good in reports but don't reveal whether your business is healthy. Six core KPIs tell you everything you need to know about e-commerce business performance - and tracking them consistently enables better decisions at every level.

The Six Essential E-Commerce KPIs

Conversion Rate (CVR)Orders / Sessions2.0-3.5% (all ecom)
Average Order Value (AOV)Revenue / OrdersCategory-dependent ($50-$300 typical)
Customer Acquisition Cost (CAC)Marketing Spend / New CustomersUnder 33% of LTV (3:1 ratio)
Customer Lifetime Value (LTV)AOV x Frequency x Lifespan3x first order value (minimum)
LTV:CAC RatioLTV / CAC3:1 minimum; 5:1 excellent
Cart Abandonment Rate1 - (Completed checkouts / Initiated checkouts)65-75% (lower is better)

Secondary KPIs by Business Stage

Early Stage (Under $1M revenue)

Focus on CVR, AOV, and repeat purchase rate. These three drive early revenue growth without needing sophisticated analytics infrastructure.

Growth Stage ($1M-$10M)

Add CAC, LTV:CAC, and cohort retention to the core six. Channel-level CAC becomes critical as you diversify ad spend across Meta, Google, and other platforms.

Scale Stage ($10M+)

Add contribution margin per channel, payback period, net revenue retention, and NPS. At this stage, margin mix and customer quality per channel determine long-term profitability.
