Tips for Maximum Savings

Use Cubic Pricing

Priority Mail Cubic is often the cheapest option for small, heavy items:

Cubic pricing based on package dimensions, not weight
- Tier 0.1: Up to 0.1 cubic feet = ~$8
- Tier 0.2: Up to 0.2 cubic feet = ~$9
- Best for items under 20 lbs in small boxes

Ideal products for Cubic:

  • Jewelry and accessories
  • Small electronics
  • Cosmetics and beauty products
  • Anything dense and compact

Package Optimization

Use poly mailers when possible20-40% vs boxes

Shopify + Pirate Ship implementation checklist (2025)

This section adds practical “make it stable” steps you can use after you install the app/connector. It’s intentionally lightweight: the goal is fewer sync surprises, cleaner reporting, and easier troubleshooting.

1) Quick setup checklist

  • Permissions first: grant only the scopes you need (orders/customers/products as required) and document who owns the admin credentials.
  • Data mapping: confirm how email, phone, currency, and SKU are mapped between Shopify and Pirate Ship.
  • Historical import: decide how far back to import orders/customers (avoid importing years of data if you don’t need it).
  • Deduplication rules: pick one unique identifier per object (usually email for customers, order ID for orders) to prevent doubles.
  • Alerts: set a lightweight alert path (email/Slack) for failed syncs, auth expiry, and API rate limits.

2) Data you should verify after connecting

Most integration issues show up in the first hour if you test the right things. Use the table below as a QA checklist (create a test order if needed).

Data objectWhat to checkWhy it matters
CustomersEmail/phone format, marketing consent fields, duplicatesPrevents double messaging and broken segmentation
OrdersOrder total, tax, discount, shipping, currencyKeeps revenue reporting and automation triggers accurate
Line itemsSKU, variant ID, quantity, refunds/returns behaviorAvoids inventory and attribution mismatches
FulfillmentStatus changes + timestamps, tracking numbers, carrier fieldsDrives customer notifications and post-purchase flows
CatalogProduct titles, handles, images, collections/tagsEnsures personalization and reporting match your storefront

3) Automation ideas for Shipping

  • Tracking notifications: fulfillment created → send branded tracking updates (email/SMS) via Pirate Ship.
  • Exception alerts: shipment exception → notify support + customer, and log reasons inside Pirate Ship.
  • Delivered follow-up: delivered event → request review/UGC or offer reorder after X days.
  • Returns loop: return initiated → update status and keep customers informed end-to-end.
  • Carrier performance: weekly report → identify late deliveries and adjust carrier rules.

API sanity check (Shopify Admin API)

If your integration UI says “connected” but data isn’t flowing, a quick API call helps confirm whether the store is accessible and returning the objects you expect.

# List the 5 most recent orders (GraphQL)
curl -X POST "https://your-store.myshopify.com/admin/api/2025-01/graphql.json" \
  -H "X-Shopify-Access-Token: $SHOPIFY_ADMIN_TOKEN" \
  -H "Content-Type: application/json" \
  -d "{\"query\":\"{ orders(first: 5, sortKey: CREATED_AT, reverse: true) { edges { node { id name createdAt totalPriceSet { shopMoney { amount currencyCode } } customer { email } } } } }\"}"

Tip: keep tokens/keys in environment variables, and test in a staging store/site before rolling changes to production.

4) KPIs to monitor (so you catch problems early)

  • Sync freshness: how long it takes for a new order/customer event to appear in Pirate Ship.
  • Error rate: failed syncs per day (and which object types fail most).
  • Duplicates: number of merged/duplicate contacts or orders created by mapping mistakes.
  • Revenue parity: weekly spot-check that Shopify totals match downstream reporting (especially after refunds).
  • Attribution sanity: confirm that key events (purchase, refund, subscription) are tracked consistently.

5) A simple 30-day optimization plan

  1. Week 1: connect + map fields, then validate with 5–10 real orders/customers.
  2. Week 2: enable 1–2 automations and measure baseline KPIs (conversion, AOV, repeat rate).
  3. Week 3: tighten segmentation/rules (exclude recent buyers, add VIP thresholds, handle edge cases).
  4. Week 4: document the setup, create an “owner” checklist, and set a recurring monthly audit.
