Open questions for wireframing

  1. Guest checkout — assumed yes for card payments; on-account billing restricted to approved trade accounts (4.5).
  2. Invoice source — generated by the site, or synced from Carriage? Affects 5.4 scope significantly.
  3. Pricing visibility — public pricing, or trade pricing revealed on sign-in?
  4. SSO providers — Google, Apple, Microsoft assumed; Microsoft likely valuable for a B2B audience.
  5. Stock display — live stock levels vs. simple in/out-of-stock indicators.
  6. Category naming — top-level follows the brochure; the van livery uses a slightly different split — align before build.

System Architecture

How the storefront, staff admin system, database and external services connect — with Carriage (K8 ERP) remaining the master for stock, pricing and invoicing.

A.2 Key Integration Flows
RefRouteWhat movesMode
F1a Carriage → API → Database Product catalogue, stock levels, trade pricing. Carriage stays the master; the website holds a synced cache so browsing never hits the ERP directly. Scheduled + delta sync
F1b API → Carriage Confirmed web orders pushed into Carriage as sales orders for picking, dispatch and account posting. Event-driven, on paid
F1c Carriage → Invoice service Invoice and statement data surfaced in the Admin system and the customer invoice portal (sitemap 5.4). Scheduled sync
F2 Storefront → Mollie → API Checkout payments and pay-outstanding-invoice payments. Mollie webhooks confirm status before orders push to Carriage or invoices are marked paid. Real-time + webhooks
F3 Notifications → Email → Customer Order confirmations, dispatch notices, invoice/statement delivery with PDF attachments, password resets, verification. Transactional
F4 Storefront ⇄ SSO ⇄ Auth Sign-in and sign-up via Google, Apple and Microsoft; identities linked to a single customer record alongside email/password. OAuth 2.0 / OIDC

Architecture decisions to confirm

  1. Carriage integration surface — confirm what K8 exposes: REST API, flat-file export, or middleware. This dictates whether F1 syncs are near-real-time or batch — the project's biggest technical risk.
  2. Invoice system of record — assumed Carriage generates invoices and the web platform mirrors them (F1c). If the Admin system raises invoices instead, the flow reverses and scope grows.
  3. Stock display strategy — agree an acceptable staleness window (e.g. 15 min), or add live availability checks at basket/checkout.
  4. On-account payments — trade credit orders bypass Mollie at checkout and settle via invoice payment; needs credit-limit checks against Carriage account data.
  5. Email provider — recommend a transactional service (Postmark, SES, Mailgun) over self-hosted SMTP for deliverability.
  6. Admin auth — staff sign-in kept separate from customer auth; Microsoft SSO for staff if Mansfield runs on 365.
