FedEx carrier integration
FedEx Shipping for CMS Max eCommerce
Connect eligible FedEx services to checkout without building a carrier stack from scratch.
CMS Max uses its Shippo integration to request eligible FedEx rates for packed parcels, present allowed services at checkout, and support downstream label and tracking workflows. Your carrier account, service eligibility, package data, and operating process still determine the real result.

Shipping architecture
A reliable shipping promise starts before the rate request.
Connect account access to accurate catalog data, parcel preparation, checkout policy, fulfillment ownership, customer communication, and financial reconciliation.
Rate estimates are not invoices
Checkout quotes can include account-specific pricing when available, but carrier adjustments, surcharges, packaging, pickup, and shipment details can change final billed cost.
Shipping is an operated workflow
Assign owners for account access, checkout testing, label purchase, exceptions, tracking, billing review, and customer communication.
CMS Max shipping capabilities
From a shippable cart to an operated delivery workflow.
Availability depends on active plugins, account mode, connected and eligible carrier services, current provider support, accurate data, origin, destination, parcel, and tenant configuration.
FedEx through Shippo
Connect an eligible FedEx carrier account in Shippo or use an available Shippo-supported carrier account, subject to current account, region, and verification requirements.
Eligible services at checkout
CMS Max sends packed parcel and address information to Shippo, receives available carrier rates, and can present allowed FedEx service levels to the shopper.
Dimensions and weight matter
CMS Max packs shippable cart items into parcel requests so rates reflect the number, dimensions, and weight of boxes instead of simply treating every product as a separate shipment.
Carrier and service filters
Restrict checkout options to selected carriers and service levels so customers see the FedEx choices the business is prepared to fulfill.
Labels, refunds, and tracking
The Shippo-backed workflow supports label purchase, supported label formats, refund requests for eligible unused labels, and carrier tracking data tied to fulfillment operations.
Fallback and API visibility
A configured flat fallback rate can preserve a checkout option during qualifying carrier-service failures, while Shippo API logs help administrators investigate requests and errors.
Order-to-delivery flow
Keep the customer choice connected to fulfillment.
Each stage needs valid inputs, observable results, an exception path, and a named owner.
Catalog
Store accurate weights, dimensions, and shipping eligibility.
Pack
Build parcel data for the shippable cart.
Rate
Request eligible FedEx services through Shippo.
Select
Present allowed options and record the choice.
Fulfill
Purchase the label, ship, track, and reconcile.
Implementation sequence
Test the real packages and real operating conditions.
Move from account ownership to checkout and warehouse testing before making a shipping promise public.
01. Define the shipping promise
Document destinations, package profiles, service levels, handling times, cutoff times, exclusions, returns, and customer-facing expectations.
02. Prepare FedEx and Shippo access
Confirm the intended account, billing relationship, authorized users, carrier verification, negotiated-rate expectations, and supported services.
03. Configure CMS Max shipping data
Set the store origin and maintain product weights, dimensions, shipping zones, methods, package rules, and any carrier or service filters.
04. Connect and test the carrier
Activate Shippo, connect FedEx, verify available services, and test realistic residential, commercial, nearby, distant, heavy, oversize, and invalid-address cases.
05. Test fulfillment
Purchase representative labels, verify print format, confirm tracking, test an eligible refund path, and document void, pickup, exception, and support procedures.
06. Monitor cost and delivery
Compare checkout charges with carrier invoices, review adjustments and fallback usage, investigate API errors, and measure delivery and support outcomes.
Operational ownership
Know which system controls each outcome.
CMS Max, Shippo, the carrier, and the merchant each own different parts of the workflow. Clear boundaries make support and recovery faster.
- CMS Max
- Stores the commerce and shipping configuration, packs cart items, presents returned choices, records orders, and provides the connected admin workflow.
- Shippo
- Provides the multi-carrier API connection, normalizes eligible rates and tracking data, and brokers supported label and refund operations.
- FedEx
- Controls carrier-account approval, available services, acceptance, transit, surcharges, billing adjustments, delivery scans, claims, and network performance.
- Merchant
- Owns data accuracy, package preparation, service promises, credentials, customer disclosures, fulfillment execution, invoice review, exceptions, and support.
Documentation and related resources
Confirm current account and carrier requirements.
Provider interfaces, terms, services, formats, and regional availability can change. Use official documentation and production tests during implementation.

Turn each answer into configured rules, representative tests, monitoring, and written ownership.
Is FedEx a separate direct CMS Max plugin?
The current CMS Max shipping architecture connects FedEx as a carrier through the Shippo plugin. Shippo supplies the multi-carrier API layer used for eligible rates, labels, and tracking workflows.
Can CMS Max show FedEx rates at checkout?
Yes, when Shippo is active, an eligible FedEx carrier account and services are available, the destination is supported, and the store provides the parcel and address data required for rating.
Will the checkout rate always equal the FedEx invoice?
No. A carrier quote is an estimate based on submitted data. Final charges can differ because of measured weight or dimensions, address corrections, fuel and residential surcharges, special services, pickup, and other carrier adjustments.
Can the store limit which FedEx services appear?
Yes. CMS Max Shippo settings support allowed-carrier and allowed-service-level filters. Availability still depends on the connected account, parcel, origin, destination, and carrier response.
Does the workflow support FedEx labels and tracking?
The Shippo-backed CMS Max workflow supports label operations and tracking data for eligible carrier services. Exact capabilities and formats depend on current Shippo and FedEx support and account configuration.
What happens if live rating is temporarily unavailable?
A CMS Max shipping method can use a configured flat fallback rate for qualifying Shippo failures. The merchant should choose that amount deliberately, monitor its use, and define when fulfillment staff must contact the customer.
Ship with confidence
Build checkout and fulfillment as one operating system.
Bring your carrier accounts, package profiles, destinations, service promises, label workflow, exception policy, and cost targets. CMS Max will help map the supported implementation.
