Customer profile
A regional building materials distributor in the GTA delivers lumber, drywall, and fixtures to active construction sites. Their buyer is an operations manager responsible for 50–120 shipments per week across Peel and Toronto corridors — squarely in Porterchain's Phase 1 ICP.
Challenge
Ad-hoc courier marketplaces handled one-off runs, but recurring jobsite routes lacked accountability:
- Missed contractor cut-offs and gate-access windows
- No consistent proof when general contractors disputed quantities or timing
- Dispatch staff spent hours reconciling three courier apps and phone updates
Solution
Porterchain aligned 16 ft box truck routes to their daily dispatch list:
- Fixed time windows encoded per jobsite (gate codes, foreman contact, lift requirements)
- Central operations coordination — one control tower for inside sales and planners
- Photo + GPS proof of delivery tied to shipment references on every drop
Results (90 days)
- 98.7% on-time delivery to agreed jobsite windows (up from 81%)
- 22% lower per-drop logistics cost versus blended ad-hoc courier spend
- 40+ weekly jobsite drops on recurring routes without adding owned fleet
- Zero POD disputes escalated to billing in the pilot quarter
"We needed pallet delivery to sites with proof our GCs would accept. Porterchain made it repeatable." — Operations Manager, GTA building supply distributor
Why this matters for B2B shippers
This is orchestration software for merchants who own the customer relationship — not a consumer courier app. The same dispatch controls, SLA visibility, and audit-ready proof chain apply across construction materials, electrical distribution, and wholesale distribution workflows.
