Product architecture

From customer order to received blanks — automated end to end.

StitchFlow orchestrates Printavo, S&S Activewear and SanMar through a deterministic rules engine. Every step is observable, overridable, and auditable.

End-to-end flow

Printavo Sync

GraphQL poll for orders hitting trigger status.

Rules Engine

Group, route and prioritize line items by SKU & vendor.

Stock Check

S&S REST + SanMar SOAP calls confirm availability.

Review Queue

Production approves drafts before placement.

PO Placement

Submit to vendor APIs, store confirmations.

Receiving + Risk

Checklists, due-date risk, write-back to Printavo.

Rules engine

flow:
  on(order.status == "Approved - Pending Materials") {
    items = expandLineItems(order)
    grouped = groupBy(items, "vendor")
    for (vendor, lines) in grouped {
      stock = vendorStockCheck(vendor, lines)
      draft = buildPO(vendor, stock.fulfillable)
      if (draft.total < $250) hold(draft)
      else queueForReview(draft)
    }
    flagRisk(order, expectedDates)
  }

Rules are versioned and editable per workspace. Disabled rules retain audit history.

Deterministic

Same input always produces the same draft POs. Every decision logged.

Override-friendly

Production can edit, split or reject any draft before placement.

Vendor-aware

Lead times, cutoffs and success rates inform routing automatically.
