What is Replenishment Marketing?
Replenishment marketing is the system that prompts customers to reorder a consumable before they run out — timed to product usage duration, not generic broadcast.
Definition
Replenishment marketing is the system that prompts a customer to reorder a consumable before they run out. The trigger is timed to the product's usage duration (per-SKU and ideally per-customer), not a generic broadcast.
The categories where replenishment is dominant: - Skincare + beauty (28-90 day usage cycles). - Supplements + wellness (30, 60, 90-day SKUs). - Pet food + treats (varies by pet + product). - Coffee + tea + pantry staples. - Personal care (toothpaste, deodorant, soap).
A consumable brand without replenishment marketing sees 40-60% of customers as one-time buyers. Same brand with replenishment marketing sees 60-80% repeat purchase. The difference is operational, not product.
Replenishment is the precursor to subscription. Customers who experience replenishment as a reminder eventually convert to subscription as a default — typically 25-40% within 6 months of engaging with replenishment prompts.
How it works
A replenishment system operates on three mechanics:
1. Per-SKU usage duration: every SKU has an expected usage duration (a 30-day supplement, a 60-day moisturiser). The system knows.
2. Trigger window: replenishment prompt fires at 80% of usage duration. For a 30-day SKU, that's day 24. For a 60-day SKU, day 48.
3. Delivery channel: SMS for urgency, email for context. Both with single-CTA reorder links.
Advanced layers: - Per-customer adjustment: if a customer reorders earlier or later, the system updates their personal cadence. - Subscription offer: at the second or third replenishment, the system offers subscription with savings. - Cross-SKU education: replenishment messages introduce complementary SKUs ("most customers add Y at this point").
The replenishment engine compounds. Every additional customer who converts to subscription via replenishment lifts the brand's recurring revenue base.
Examples and data
A supplement brand at $1.5M revenue:
Pre-replenishment engine: 28% repeat-purchase rate, no subscription. Post-engine: 62% repeat-purchase rate, 31% subscription conversion via replenishment prompts. LTV per customer moved from $115 to $310. Annual revenue at 12 months: $4.2M (with same acquisition spend).
A skincare brand at $4M revenue:
Pre-engine: 35% repeat-purchase rate. Post-engine: 71% repeat-purchase rate. Subscription rate moved from 8% to 38%. LTV moved from $145 to $390.
A coffee DTC brand at $2M revenue:
Pre-engine: 41% repeat-purchase rate. Post-engine: 78% repeat-purchase. Subscription rate moved from 22% to 54%.
The investment is one-time + ongoing tuning; the revenue is recurring and compounds.
The Edynamics lens
Edynamics deploys the replenishment engine as one of the highest-leverage B2C playbooks. The per-SKU usage durations land in the platform on day 1; the trigger sequences ship in week 1; the subscription conversion layer ships in week 2; the cross-SKU education ships in week 3. By month 2 the engine is producing measurable LTV lift.
