Three things to note. First, these numbers are for brands running a coherent retention stack — not for under-built programs (which spend less and earn less) or over-engineered ones (which spend more and earn the same). Second, they assume Shopify Plus as the platform; Basic and Advanced run lower because the app ecosystem is more limited. Third, they exclude paid acquisition and tax/finance/customer-service — pure retention only.
The right way to read this guide: locate your brand size in the first table for the all-in number, then drill into the workstream table for the line-by-line spend. If you’re materially below the band, you’re under-built (and probably leaving 15–25% of LTV on the table). If you’re materially above, you’re likely paying for redundant programs or under-utilizing what’s already on contract.

By brand size
| Tier | Monthly revenue | Retention spend | Notes |
|---|---|---|---|
| Pre-$5M | Under $5M GMV | $2K–$5K/month | Klaviyo + reviews + basic loyalty if applicable. Most brands here should not yet pay for a subscription app or a serious SMS program — the spend doesn’t pay back. Focus the budget on Klaviyo flows and reviews. |
| Foundation ($5M–$10M GMV) | $5M–$10M GMV | $7K–$15K/month | Klaviyo + Postscript + reviews + (if SKU fits) a subscription app + a loyalty app. One in-house retention generalist (~$80K–$120K/year). A fractional strategist 8 hours/month. This is the band where the retention stack starts compounding meaningfully. |
| Scale ($10M–$25M GMV) | $10M–$25M GMV | $18K–$32K/month | Two in-house (retention lead + email/SMS specialist). Subscription program live with active sub % climbing to 20%. Loyalty mature and tier-segmented. App spend climbs because % of GMV pricing on Recharge / Smartrr / Postscript scales with the program. Fractional strategist promoted to quarterly retainer. |
| Compound ($25M–$50M GMV) | $25M–$50M GMV | $35K–$60K/month | Three-person retention team (lead + lifecycle specialist + subscription operator). Retention-specialist agency on retainer for subscription operations, lifecycle expansion, and win-back programs. App spend significant: subscription app at 1.0–1.5% of sub-GMV, Klaviyo + Postscript scale with profile counts. |
| Enterprise ($50M+ GMV) | $50M+ GMV | $60K–$200K+/month | 4-plus in-house retention operators. Multiple agency retainers (lifecycle + subscription + loyalty often run by different specialists). Klaviyo or enterprise CRM at six figures/year. Subscription app at $20K–$40K/month at 1%+ of sub-GMV. Custom reporting and data infrastructure built in-house. |
