Shopify Admin Customer Spend Tier Tagger

Purpose

Queries all customers, calculates their lifetime spend using order history, and assigns a spend-tier tag (Bronze/Silver/Gold/Platinum by default). Enables VIP segmentation for loyalty programs, exclusive offers, and CX prioritization without a third-party loyalty app. Extends the existing loyalty-segment-export skill with a write step.

Prerequisites

• Authenticated Shopify CLI session: shopify store auth --store <domain> --scopes read_customers,read_orders,write_customers
• API scopes: read_customers, read_orders, write_customers

Parameters

Default tiers (store currency):

bronze:   $0–$249
silver:   $250–$999
gold:     $1,000–$4,999
platinum: $5,000+

Safety

⚠️ tagsAdd adds tags to customer records visible to staff and used by marketing segments. If remove_old_tiers: true, existing tier tags matching tag_prefix are removed before new ones are applied. Run with dry_run: true to review the tier distribution before committing.

Workflow Steps

1. OPERATION: customers — query Inputs: first: 250, select id, amountSpent, pagination cursor Expected output: All customers with lifetime spend; paginate until hasNextPage: false

2. Assign tier to each customer based on amountSpent.amount vs. tiers thresholds

3. OPERATION: orders — query (optional — for verification of spend figures)

4. OPERATION: tagsAdd — mutation Inputs: Customer id, tags: ["<tag_prefix>:<tier>"] Expected output: Updated customer tags; userErrors

Session Tracking

Claude MUST emit the following output at each stage. This is mandatory.

On start, emit:

╔══════════════════════════════════════════════╗
║  SKILL: Customer Spend Tier Tagger           ║
║  Store: <store domain>                       ║
║  Started: <YYYY-MM-DD HH:MM UTC>             ║
╚══════════════════════════════════════════════╝

After each step, emit:

[N/TOTAL] <QUERY|MUTATION>  <OperationName>
          → Params: <brief summary of key inputs>
          → Result: <count or outcome>

If dry_run: true, prefix every mutation step with [DRY RUN] and do not execute it.

On completion, emit:

For format: human (default):

CSV file tier_tagging_<YYYY-MM-DD>.csv with columns: customer_id, name, email, lifetime_spend, currency, tier, previous_tags, new_tags

Error Handling

Best Practices

• Run monthly to keep tier assignments current — customers who increase their spend will move up tiers automatically.
• Use remove_old_tiers: true to ensure each customer has exactly one tier tag at any time.
• Adjust tiers thresholds to your store's AOV and LTV distribution — the defaults work for stores with $50–100 AOV.
• After tagging, create Shopify Customer Segments using tag filters to target each tier in email campaigns.
