Why 3PLs Choose ParcelOffice

Rapid Client Onboarding

Connect WooCommerce or PrestaShop via seamless SSO plugins and start receiving orders immediately. No brittle custom builds.

Automated Carrier & Label Logic

Rules-based engine selects the best carrier, service level, and correct label type/quantity for each order — consistently.

Barcode‑First Packing

Scan-to-print workflows with UI Facts: operators scan order/product, confirm options, and print the right labels instantly.

EDI / ASN, PDF, CSV, JSON

Flexible Twig templating to generate retailer-compliant EDI/XML, ASNs, and documents from fact values.

Client‑Specific Rules, Versioned

Per‑client configurations with publishing & rollback. Facts are immutable snapshots at evaluation time for traceability.

APIs & Webhooks

Push/pull orders, events, and tracking. Action Facts can call external systems and pause until a result returns.

Proven Integration Patterns for 3PL Providers

1) Storefront Connectors (WooCommerce & PrestaShop)

  • Secure iframe‑based plugins with JWT SSO for zero‑friction merchant onboarding.
  • Orders ingested in real time; updates (status/tracking) posted back automatically.
  • Supports multi‑store and client‑segmented configurations.

2) WMS & Carrier Systems

  • Use ParcelOffice as the decision layer for carrier selection and label type/quantity.
  • Plug into your WMS via API/webhooks or run as a sidecar with scan UI screens.
  • Reflective Facts (hourly system facts) reduce overhead for global constraints.
Keyword: shipping label automation

3) EDI / Retailer Portals

  • Map mass‑config sheets to retailer EDI templates (via Twig) with row‑level __gate logic.
  • Generate ASNs, packing lists, and compliance docs from immutable fact snapshots.
  • Deliver via SFTP/HTTPS; rotate credentials in admin without republishing facts.
Keyword: EDI ASN for 3PL

4) Operator UX: UI Facts

  • Interactive, version‑controlled UIs that render based on earlier facts (e.g., weight, postcode, carrier eligibility).
  • Keyboard, barcode, and RFID input supported; once saved, the value becomes immutable.
  • Perfect for scan‑to‑confirm workflows at packing stations.
Keyword: barcode-driven packing

5) Action Facts (Async)

  • Trigger external calls (CTAs, APIs, label services) and pause evaluation until a result is returned.
  • Supports parallelism where safe; great for product‑level decisions inside an order.
  • Keeps a single, auditable session flow without fragmenting objects.
Keyword: workflow automation for 3PL

6) Mass‑Config & Versioning

  • Upload namespaced CSVs for carrier matrices, surcharges, dimension caps, and service gates.
  • Use sheet‑level and row‑level gates to control applicability per client or channel.
  • Publish as a set; rollback safely with full debug traces by tier.
Keyword: rules-based fulfilment

Typical 3PL Onboarding Flow

  1. Connect Storefront (WooCommerce/PrestaShop) — orders start flowing.
  2. Import Carrier Config — rates, limits, service levels via mass‑config.
  3. Define Facts — standard + SmartFACTs for weight, dims, destination, SLAs.
  4. Add UI Facts — scan‑to‑print screens tailored to your packing desks.
  5. Wire EDI/ASN — Twig templates + secure delivery to retailer endpoints.
  6. Publish & Go Live — version locked; debug logs retained by tier.

What You’ll Automate

  • Carrier selection by destination, weight/dims, and SLA.
  • Label type & quantity per order or per product line.
  • Retailer‑specific documents (ASN, packing list, UCC128).
  • Status and tracking updates back to storefronts.

All decisions are traceable back to the fact snapshots used at evaluation time.

Technical Highlights

APIs & Webhooks

REST endpoints to ingest orders and query facts; webhooks for events (created, evaluated, shipped, error).

Security & Access

Per‑client isolation, JWT SSO for embedded admin, role‑based controls, credential rotation outside versioned facts.

Observability

Debug timelines of every decision; retention by subscription tier with upgrade prompts for extended history.

Frequently Asked Questions

Can ParcelOffice sit alongside our existing WMS?

Yes. Many 3PLs use ParcelOffice as the decision engine for carrier & label selection while keeping their WMS for inventory and pick/pack.

How are client rules isolated?

Each client has its own version‑controlled configuration. Facts are evaluated into immutable snapshots, ensuring stable routing and reliable audits.

Do you support retailer‑specific EDI/ASN?

Yes. Use Twig‑based templates plus mass‑config gates to target exact retailer schemas and deliver via SFTP/HTTPS.

What about barcode/RFID at packing?

UI Facts support keyboard, barcode, and RFID input. Operators can scan order refs and on‑screen choices for fast, low‑error throughput.
