Memberships, software and services
- A buyer must sign in before accessing an order or entitlement.
- Support must see the same order reference and payment state.
- Account deletion, refunds and disputes need an audit trail.
IDENTITY → ORDER → SUPPORT
Keep every customer action on one identity and order.
A website with separate login, checkout and support tools creates gaps exactly where trust matters. TC SiteOS gives the buyer one verified identity, creates the order on the server, hands payment to a runtime-ready provider, then keeps support, return status, delivery and audit tied to the same reference. No screenshot guessing and no duplicate customer record.

Who this architecture is for.
It is designed for businesses where identity or order history affects support, entitlement, delivery or account safety.
Anonymous brochure-only sites
- No account, order, support or delivery state exists.
- The business wants browser-only records with no server authority.
- There is no authorized operator for sensitive escalations.
The complete identity-to-support delivery.
Each layer is independently testable and connected through documented identifiers rather than visual assumptions.
Provider-gated sign-in
OAuth, email code and password fallback appear only within their verified runtime contract.
Server price and reference
The server selects the catalog item, amount and currency before any payment handoff.
Robot plus human ticket
Common questions stay fast; money, account safety and disputed delivery escalate with the order attached.
Display is not payment truth
A return page shows progress but cannot self-confirm payment; trusted events update the ledger.
One customer record
Profile, orders, tickets, payment records and entitlements remain under the same identity.
A traceable operating trail
Relevant account, order, support, payment and delivery changes produce operator-visible evidence.
Implementation sequence and timing.
The 3–5 business day window applies to the approved SiteOS baseline after required provider and owner inputs are available.
Identity contract
Define methods, verified fields, roles, session and recovery boundaries.
Order contract
Lock products, price source, currency, return path and idempotency.
Support contract
Connect robot answers, ticket categories, escalations and operator evidence.
End-to-end QA
Test the buyer path, failure path, mobile layout and bilingual state.
INTERNAL DEPLOYMENT CASE STUDY

The public TC SiteOS deployment exposes the account, product, order, payment handoff, support and audit surfaces without claiming unavailable provider credentials or fabricated commercial results.
Frequently asked.
The identity and payment boundary is designed to fail closed when production dependencies are absent.
Why should login and checkout share one identity?
A shared identity prevents orders, payment records and support tickets from becoming disconnected records. Each action can be traced to the same verified user and order reference.
Can unverified users pay?
The recommended SiteOS flow requires the configured identity gate before guarded payment handoff. The exact login methods depend on approved production providers.
What happens when payment or delivery has a problem?
The buyer can open a support ticket linked to the same order. Sensitive payment, refund, account and delivery cases escalate to authorized human review.
