Shopify App for ShipStation Merchants

Stop Overpaying Duties on Discounted Orders

ShipStation declares customs values at full retail price, even when your customers paid less. Declared fixes that automatically.

ShipStation Gets Customs Values Wrong

ShipStation handles line-item discounts just fine. But when an order-level discount is applied — discount codes, automatic promotions, Shopify Scripts — ShipStation still declares the full retail price on customs forms for international shipments.

Your customers end up overpaying on import duties and taxes — and you deal with the complaints, refund requests, and abandoned repeat purchases.

This has been a known problem on the ShipStation community forums for over 8 years, with no fix in sight.

Example: $100 item with 30% discount
Customer paid $70.00
ShipStation declares $100.00 ✗
Duties calculated on $100.00
With Declared
Customs value corrected to $70.00 ✓
Duties calculated on $70.00

How Declared Fixes It

Fully automated. No manual work, no spreadsheets, no custom scripts.

1

Detect

Shopify sends a webhook when an international order with a discount is created. Declared picks it up instantly.

2

Calculate

We pull the actual discounted price from Shopify, match SKUs to ShipStation, and build corrected customs declarations.

3

Correct

The corrected customs values are pushed to ShipStation via API before you ship — or queued for your review first.

Built for Reliability

Everything you need to keep customs values accurate across every international order.

Auto-Detection

Listens for Shopify webhooks to detect international orders with order-level discounts that ShipStation misses. No manual tagging or filtering.

🏷

All Discount Types

Handles discount codes, automatic order discounts, Shopify Scripts, wholesale pricing, and any combination that ShipStation doesn't account for. Uses Shopify's own final-price field.

Auto or Review Mode

Push corrections automatically, or queue them for manual review before they reach ShipStation. Your choice, per-store.

🔗

SKU Matching

Maps Shopify SKUs to ShipStation line items so corrections land on the right products, even when identifiers differ.

📧

Email Alerts

Get notified about processing errors, orders needing review, and when you're approaching your plan's order limit.

📊

Dashboard & Analytics

Full order history, processing status, duty savings tracking, and analytics — all inside your Shopify admin.

🔒

Encrypted Credentials

ShipStation API keys are encrypted at rest with AWS KMS (AES-256). Never stored in plaintext, never logged.

Verification

After pushing to ShipStation, we read back the order to verify the values were applied correctly. No silent failures.

Knows which countries require customs declarations and only processes orders that actually need correction.
