TL;DR

  • Connect a 3PL via plugin or API. Sync orders and inventory both ways.
  • Map services to WooCommerce shipping methods and packaging rules.
  • Automate labels with carrier rules (Royal Mail, Evri, DPD) and scan‑to‑print.
  • Multi‑warehouse: Route by region/SKU, split shipments, and keep tracking in sync.
New to 3PLs? Start with one site + one carrier. Add more warehouses/carriers once the core flow is stable.

What is a 3PL for WooCommerce?

A third‑party logistics (3PL) provider stores your inventory and performs pick‑pack‑ship on your behalf. A proper WooCommerce 3PL integration imports orders automatically, applies service rules, prints labels, and sends tracking back to customers.

  • Reduced handling: Warehouse teams pick/pack; your team focuses on growth.
  • Better carrier rates: 3PLs aggregate volume across clients.
  • Peak elasticity: Scale without hiring surge staff.

Step‑by‑step: WooCommerce → 3PL

  1. Choose a 3PL (location, SLAs, packaging, carrier mix, onboarding).
  2. Install/connect your integration and authorise WooCommerce.
  3. Map services (Standard/Express/Intl) to carrier products and 3PL workflows.
  4. Define packaging by weight/size/fragility; set default boxes/bags.
  5. Enable rules to select Royal Mail/Evri/DPD based on order facts.
  6. Test scan‑to‑print, multi‑parcel consignments, and returns labels.
Pro tip: Keep SKU weights and dimensions accurate. Most mis‑priced shipments trace back to product data.

Label automation (Royal Mail, Evri, DPD)

  • Royal Mail: Tracked 24/48 for small/light parcels; 100×150 mm labels. Consider Click & Drop or API.
  • Evri (Hermes): Cost‑effective standard parcels; test 203 - 300 DPI output for readability.
  • DPD: Premium domestic with 1‑hr windows; enable multi‑parcel consignments when needed.

FAQs

Can I split one WooCommerce order across warehouses?

Yes. Enable split shipments. ParcelOffice creates separate consignments for each origin and syncs tracking back to a single order.

Do I need separate integrations per carrier?

No. You can centralise carrier logic in ParcelOffice or via your 3PL. Rules choose the carrier by weight/size/region and push the right format (PDF/ZPL).

What label size should I use?

Use 100×150 mm (4×6″) at 203 - 300 DPI. Disable “fit to page” in the print dialog and set scale to 100%.
