Everything you need to make Cash on Delivery pay for itself.

One app, four jobs: charge the right fee, block the wrong orders, catch repeat offenders, and show you the numbers behind all of it.

01 — COD FEE

Charge for the risk COD actually carries.

Every store handling Cash on Delivery absorbs extra logistics and cancellation risk. CODGuard lets you price that in — cleanly, and only for the buyers who choose it.

Link your Cash on Delivery payment method to a fee-carrying shipping rate — the fee applies the moment a buyer selects COD at checkout.
Prepaid buyers keep their existing free or standard rate — nothing changes for the orders you already wanted.
No separate checkout app and no Liquid edits — the fee lives in your native Shopify shipping rates.

How CODGuard works
Checkout picks a shipping rate before a payment method — CODGuard uses your COD rate to control when Cash on Delivery shows.
Cash on Delivery rates
CODGuard reprices the rate you pick for COD to your fee, and the rate for advance payment to free.

02 — BLOCK RULES

Stop the risky order before it's placed, not after.

Build rules from the conditions that actually predict a failed COD delivery, combine them with AND/OR logic, and set the priority order they fire in.

Hide COD entirely, or just make it more expensive — the action is yours to choose per rule.
Stack conditions across country, pin code, product, cart value, shipping method, and customer history.
Prepaid checkout is never touched — only Cash on Delivery availability is affected.
03 — RISK & RTO ANALYTICS

See exactly who and where is driving your RTO.

CODGuard tracks every COD cancellation and return, then flags the customers and pin codes with a repeat pattern — before they place order number three.

Automatic flags for repeat-cancel customers and high-RTO pin codes, ready to turn into a block rule.
COD vs. prepaid split, fee revenue, and RTO rate trend on one dashboard.
Built on Shopify's Protected Customer Data access, so only what's needed for risk tracking is ever touched.

Customers and pin codes exceeding the cancel/RTO threshold — flagging one hides Cash on Delivery on their next checkout.

COD availability badge

A theme app extension block you drag onto any product or section — tells shoppers COD is available right where they're deciding to buy, with zero impact on page speed.

Guided onboarding

The setup wizard creates a Cash on Delivery rate and a free prepaid rate in your shipping zone automatically, or works with rates you've already built.

Dashboard & trends

COD vs. prepaid split, fee revenue, blocked-order counts, and your RTO rate trend — the numbers you need to prove a rule is working, in one place.
