Double-clicked checkouts and retried payments can create orders your customer did not mean to place. Hexloom Duplicate Orders compares each new order with the same customer's recent orders and flags likely duplicates, so you can cancel the extra one before it ships. It flags likely duplicates and cannot know the customer's intent; you decide. It does not merge orders; it cancels, with your choice of refund and restock. Nothing is stored beyond hashed buyer ids and order ids.

• Flags same-customer, same-item orders inside a window you set (5 min to 24 h)
• Shows a confidence level and the reason for each flag
• Cancel the extra order with refund and restock; fulfilled orders never offered
• Daily digest inside the app, no email
• Scans the last 30 days on install, then checks each new order

Wholesale buyers upload a resale or status-card certificate on a page that matches your theme. You approve or reject each in a queue. Approval sets Shopify's own exemption: resale for US states, BC, MB and SK, plus Canadian status-card and diplomat certificates. For any other, you confirm a full exemption first. It applies when the buyer is signed in. Buyers get an email on approval, rejection and before expiry. For US and Canadian stores. You decide what is valid; this is not tax advice.

• One review queue: download, approve, reject with a reason, or revoke
• Sets Shopify's resale exemption for US states, BC, MB, SK; others need your OK
• Emails buyers on approval, rejection, 30 days before expiry and at expiry
• Removes the exemption on the expiry date; files stored encrypted

Reads each product's HS code (US code first) and country of origin. The code is matched against the US Section 338 annex lines (goods made in Canada); the origin sets the Section 301 note. Every match shows its source and as-of date. Products with no HS code are counted and filterable; unmatched products show as not found, never cleared. Read-only: it never reads orders or customers. Tables were transcribed from public annexes with AI assistance and may miss a line. Not legal or customs advice.

• See which products fall on a Section 338 line, and at what rate
• Every match cites its source and as-of date
• Look up any HS code against the listed lines
• Products with no HS code are counted and filterable so you can fill them in
• Plain next steps: reprice, add the duty at checkout, or ask a customs broker
