Printavo integrations
that automate
blank POs
end to end.

I build internal apps that pull orders from Printavo (GraphQL), check stock across S&S and SanMar, group vendor POs with business rules, run human review, place orders via API, and write tasks and expenses back to Printavo—with multi-tenant architecture from day one.

// what_shops_face

Blank garment PO work is buried in tabs. That’s where mistakes hide.

Teams copy order lines between Printavo, S&S, SanMar, spreadsheets, and email. It works until volume grows—then wrong SKUs, split shipments, and missed due dates become expensive. Typical failure modes:

!

No single trigger from Printavo status

Impact: Late or skipped POs
!

Stock checks done manually per vendor

Impact: Slow + inconsistent
!

Business rules live in people’s heads

Impact: Wrong grouping / splits
!

Orders placed without a review checkpoint

Impact: Costly corrections
!

Receiving disconnected from customer invoices

Impact: Floor chaos
!

No write-back to Printavo for tasks/spend

Impact: Blind job costing

How I Ship Printavo + Vendor V1 Apps

Same stack you’d expect for a serious internal tool: typed APIs, adapter boundaries, review UX, observability, and documentation your team can own after launch.

01

Domain + Status Triggers

Map Printavo order states to automation triggers; define idempotency so the same job never double-runs.

02

Vendor Adapter Framework

Normalize every vendor behind one interface: inventory, cart, submit PO, track shipment—REST or SOAP.

03

Rules Engine + PO Bundling

Encode how lines roll up into vendor POs: minimums, freight buckets, split rules, rush lanes.

Review UI + Placement

Branded, mobile-friendly review screen; one-click place order with confirmation capture.

05

Receiving + Printavo Write-Back

Printable checklists by invoice; shipment risk alerts; tasks and expense entries back to Printavo.

Detailed case studies (what clients need)

Representative builds aligned with apparel shops automating blank garment POs—Printavo in, vendors out, humans in the loop, full audit trail.

Custom Apparel Shop — Blank Garment PO Automation (Printavo → S&S + SanMar)

What the client needed

Replace manual copy-paste between Printavo and vendor portals when orders hit production-ready status. Reduce wrong-SKU orders, speed up purchasing, and give production a receiving checklist tied to customer invoices.

Delivered a multi-tenant V1 internal app: GraphQL sync from Printavo on configurable status transitions, parallel inventory calls to S&amp;S Activewear (REST) and SanMar (SOAP), rule-based PO bundles with overrides, manager review screen, API placement to both vendors, printable receiving sheets grouped by invoice, shipment tracking with due-date risk flags, and write-back of tasks + expense lines to Printavo jobs.

2 vendor adapters + tests

PDF receiving packs
  • Printavo: polling + webhook-style triggers with dedupe keys per order line batch so replays never duplicate vendor carts.
  • Vendor layer: abstract InventorySnapshot, PlaceOrderResult, ShipmentEvent—implemented S&amp;S REST and SanMar SOAP with typed errors and vendor-specific rate limits.
  • Rules: configurable JSON/YAML bundles for minimum order value, freight lanes, split-by-warehouse, and “rush” lanes that bypass batching when customer due date is inside N days.
  • Review UI: responsive queue showing stock deltas, substitution suggestions when qty unavailable, and explicit approve/reject with comment trail.
  • Ops output: per-invoice receiving checklist PDF + optional barcode-friendly line lists for the dock.
  • Risk: ETA vs customer ship-by date with amber/red banners when carrier delays threaten in-hands dates.
  • Printavo write-back: creates tasks for purchasing exceptions and posts estimated garment expense entries tied to job IDs for costing visibility.

Multi-Tenant Shop Platform — Same Stack, Isolated Tenants

What the client needed

Design for one shop today with a roadmap to onboard additional decoration businesses—each with own Printavo credentials, vendor accounts, rules, and branding—without code forks.

Built tenant-scoped data model (organization → shops → users), encrypted credential vault per tenant for Printavo and vendor API keys, feature flags per tenant, and shared adapter binaries with tenant-specific configuration. Admin console for inviting users and rotating credentials safely.

Row-level tenant isolation
Secrets per tenant
Single deploy
White-label UI tokens
  • Database: every PO, vendor response, and audit row keyed by tenant_id; optional shard-ready IDs for future scale.
  • Auth: role-based access (buyer, manager, admin) with MFA-ready session layer for internal tools.
  • Configuration: tenant YAML for rules + vendor mapping without redeploy; validation on save with preview diff.
  • Observability: per-tenant job dashboards—failed placements, SOAP faults, GraphQL rate-limit hits.

Vendor Adapter Framework — Plug-In Modules & Safe Failures

What the client needed

Treat each wholesaler as a plug-in: swap or add vendors without rewriting core PO logic; surface actionable errors when APIs change.

Implemented a strict adapter contract (capabilities, inventory batching, cart validation, submit, track). Each vendor ships as an isolated module with contract tests against recorded fixtures. Circuit breakers for flaky SOAP endpoints; structured logging for support handoff.

Circuit breaker + backoff
Fixture replay CI
  • Version adapters independently; core app depends only on interfaces + JSON schemas for payloads.
  • Map vendor-specific errors to user-facing codes (“OUT_OF_STOCK”, “AUTH_EXPIRED”, “MIN_ORDER_NOT_MET”).
  • SOAP: WSDL-driven client generation where applicable; request/response logging redacted for PII.
  • REST: OAuth or API-key flows isolated per tenant with refresh handling and clock-skew tolerance.

Architecture for Printavo + vendor PO automation

Layers that match how serious shops operate: integrations first, rules second, humans approve, everything is observable.

A

Printavo Integration Layer

GraphQL queries/mutations, job-level writes, task + expense sync, webhook or polling triggers.

B

Orchestration + Rules

Status-driven workflows, PO grouping, idempotent jobs, audit trail per batch.

C

Vendor Adapter Framework

Pluggable REST/SOAP modules: inventory, cart, submit, track—typed errors & retries.

D

Review & Placement UI

Branded responsive screens for managers: queue, diffs, approvals, confirmations.

E

Receiving + Reporting

Invoice-grouped checklists, PDF generation, shipment ETA vs due-date risk scoring.

F

Multi-Tenant + Ops

Tenant isolation, secrets, per-tenant config, monitoring, runbooks, documentation handoff.

Let's scope your Printavo + vendor V1.

Bring your status triggers, vendors, and rules-of-thumb from the shop floor. I'll map an end-to-end plan: integrations, review UX, multi-tenant boundaries, and clean documentation for your team.
