Key Takeaways

Payment authorization/capture
Order confirmation pipeline
Identity and session lifecycle
Promotions and tax calculations at checkout
Cart assembly and pricing

Overview

Source page: https://yumbrands.atlassian.net/wiki/spaces/reo/pages/4154720382/Byte+Commerce

Scope

Byte Commerce powers ordering flows: menu/catalog, cart, promotions, loyalty, taxes, payments, order orchestration, and related APIs.

Core dependency chain

Frontend -> gateway -> cart/menu/auth/payment/order/workflow -> downstream store/POS systems

High-risk areas

Payment authorization/capture
Order confirmation pipeline
Identity and session lifecycle
Promotions and tax calculations at checkout

Incident triage by journey phase

Acquisition and browse
Cart assembly and pricing
Payment auth
Order submission and workflow orchestration
Confirmation and downstream eventing

Failure signatures

Auth success but checkout failure: payment/order boundary issue
Submission success but confirmation drop: workflow/downstream issue
Price/promo drift: catalog/promo/tax dependency issue

Escalation strategy

Route by owning service team first.
Add dependency owners based on journey stage.
Include vendor checks for payment and delivery dependencies.
