E-commerce on the Software Lifecycle Cloud

E-commerce on KERNSTACK owns the parts of commerce that constitute the business: the catalogue and its search, carts and checkout state, the order lifecycle, raw payment events reconciled into provable order states, and fulfilment workflows with human steps for the exceptions. Cards stay with the payment provider; the data that makes the business worth buying moves onto infrastructure the merchant controls, in Europe.

Regulatory & Sovereignty Context in E-commerce

Commerce regulation is mostly about promises and records: the price displayed is the price charged, orders and invoices are retained and retrievable, refunds follow a trail, and customer data obeys the usual European duties of residency, erasure, and evidence. KERNSTACK’s shape supports those duties plainly — catalogue prices read live from one table (so search results cannot quote a stale price), order states derive from stored payment events, retention is declared per record, and the whole shop’s data sits in one European zone a merchant can name in their privacy documentation.

The order is a state machine, not a status field

Most commerce pain concentrates in order states that were asserted rather than derived: “paid” because a redirect looked successful, “shipped” because someone meant to update it. On KERNSTACK the provider’s payment events are stored raw and order states derive from them; fulfilment advances through workflow steps — pick, pack, ship — and exceptions (address unclear, item damaged, customer unreachable) park at human steps with the order attached instead of becoming email.

Merchandising on one source of truth

Catalogue, search, and recommendations read the same product table. A price change is visible in search when it is true, synonyms learned from support tickets become merchandiser-owned data, and zero-result queries log themselves into next week’s merchandising agenda. The shop stops paying the stale-copy tax that assembled storefronts charge in conversion.

  • Displayed prices are live reads — search and checkout cannot disagree about money
  • Refunds pass a human step with the payment-event trail attached; the approval is recorded
  • Customer erasure runs over the same subject fields as every other record type in the project

Domain Entities & Workflows Modeled in stack.json

Teams building for E-commerce on the Software Lifecycle Cloud model their core domain entities directly in Serverless Tables, index them in Full-Text and Vector Search, and coordinate multi-actor approvals with Workflows:

  • Core Data Entities: products · carts · orders · payment events · fulfilment tasks
  • Typical Automated Workflows: catalogue publish · checkout · refund approval · fulfilment exception · returns intake
FAQ

Frequently asked questions

No. The backend — catalogue, cart, orders, fulfilment — can move into your project while the storefront keeps calling APIs. Merchants usually start there, because that is where order truth and the 3 a.m. reconciliation problems live.

A refund is a workflow ending at a named human step, with the order and its raw payment events attached. The provider executes the approved refund; the approval, its author, and the amount are project records.

Yes. Customer-related records carry subject fields, so erasure runs as the retention workflow over orders, carts, and messages — with the statutory carve-outs (invoices under retention) handled as declared exceptions rather than improvisation.

E-commerce · Specialized ArchitectureEcommerce backend for E-commerceE-commerce backend for merchants: catalogue and checkout in your project, payment events reconciled raw, fulfilment as workflow steps.E-commerce · Specialized ArchitectureCatalog search for E-commerceCatalog search for merchants: a declared index over live products, synonyms as merchandising data, zero-result queries as the agenda.Use Case · CommerceCatalog searchThe products table is the only catalogue; the text index is declared over its searchable fields and rebuilds from it. The search function combines index hits with live reads — facet counts, stock states, prices — so merchandising rules (boost this season’s line, bury out-of-stock) are code and data in the project, reviewable before the sale starts, not a vendor console’s drag-and-drop.Use Case · CommerceEcommerce backendCatalogue rows carry price, stock, and the fields the text index searches; a cart is a session-keyed record the storefront functions read and write. Checkout creates an order row and hands payment to the provider; the provider’s webhooks return as stored raw events that a worker reconciles into order states, so “paid” is a derived, provable state. Fulfilment steps — pick, pack, ship, the occasional human “call the customer” — run as a workflow per order.Role · AgenciesKERNSTACK for AgenciesStudios delivering client projects repeatedly — without adopting each client’s cloud account, or leaving credentials in a password manager as the handoff.Role · CTOsKERNSTACK for CTOsEngineering leaders accountable for residency, review discipline, security posture, and a cloud bill that can be explained to a board.Role · FoundersKERNSTACK for FoundersFounders shipping the first production system without a platform hire — where the stack must be operable by the people who also sell and support it.
