How to Price Shopify Builds & Growth Retainers in 2026

Three pricing tiers by store sophistication, with growth retainer baked in.

2 min read·Published 2026-04-23

Why Shopify is its own pricing category

Shopify projects span a 10× price range — from a Dawn theme tweak ($5K) to a full Plus + Hydrogen headless build ($150K+). The agencies winning are tiered cleanly so prospects self-select.

The 2026 Shopify benchmark

Theme Build — $1M-$5M ARR brand

  • Fixed-fee: $12,000
  • Shopify theme customization (Dawn or premium)
  • Up to 10 product templates + collection layouts
  • Mobile-first responsive design
  • Basic app stack (Klaviyo, reviews, search)
  • Launch checklist + Google Merchant feed
  • 30-day post-launch support
  • Timeline: 6-8 weeks

Custom Store — $5M-$25M ARR brand

  • Fixed-fee: $35,000 + $4,500/mo retainer
  • Min retainer: 6 months
  • Custom theme from scratch (Liquid + Hydrogen optional)
  • Advanced PDP + landing page builder integration
  • Subscription / bundling app integrations
  • Conversion optimization retainer (1-2 A/B tests/mo)
  • Klaviyo email + flows setup
  • Quarterly merchandising reviews
  • Timeline: 10-14 weeks

Plus + Headless — $25M+ ARR brand

  • Fixed-fee: $90,000 + $12,000/mo retainer
  • Min retainer: 12 months
  • Shopify Plus implementation
  • Headless storefront (Hydrogen + Oxygen, or Next.js + Shopify Storefront API)
  • B2B portal + wholesale catalog
  • Multi-region / multi-currency setup
  • Dedicated dev + designer retainer (32h/mo)
  • Weekly performance + revenue reviews
  • Timeline: 16-24 weeks

When to require Shopify Plus

Don't recommend Plus to brands under $5M ARR — they don't need it and the $2K/mo Plus license eats their margin.

Plus is right when:

  • Doing $5M+ in Shopify GMV
  • Need wholesale/B2B portal
  • Need multi-store (region, brand, language)
  • Need custom checkout (Shopify Plus exclusive)
  • Need higher API rate limits (custom integrations)

The retainer math that matters

For Custom Store ($35K + $4.5K/mo):

  • Year 1: $35K build + $54K retainer = $89K total
  • Year 2: $54K retainer
  • Year 3: $54K retainer

That's $197K over 3 years for one client. The retainer is where the LTV lives. Implementation-only Shopify projects are a margin trap.

Where to upcharge

  • Klaviyo email setup ($5,000-$12,000) — flows + segmentation + templates
  • Subscription + bundling apps ($3,000-$10,000) — Recharge, Bold, Loop
  • B2B portal ($15,000-$40,000) — wholesale catalog, NET terms, multi-tier pricing
  • Custom app development ($10,000-$50,000+) — proprietary functionality
  • Performance audit ($3,000-$8,000) — store speed, app bloat audit, image optimization

What to avoid

  • Theme builds for >$10M ARR brands. They need custom; theme work won't scale.
  • Plus migration without retainer. Plus is a system, not a product — needs ongoing optimization.
  • No DTC subscription scope. 80%+ of growing DTC has subscription — bake it in or you'll be replaced.
