Case Study: Independent Timber Merchants Co‑operative Limited achieves hands‑free automated invoicing with SPS Commerce

Independent Timber Merchants Co-operative Limited - Customer Case Study

Independent Timber Merchants Co‑operative (ITM) is a $1.6B NZD, Auckland‑headquartered cooperative that supports 90+ independent hardware stores across New Zealand with centralized billing. Rapid growth exposed a reliance on manual invoice entry and multiple invoice formats, creating inaccuracies and a scalability bottleneck that threatened future expansion.

ITM implemented Oracle NetSuite alongside SPS Commerce Fulfillment to automate EDI invoicing, creating a single source of truth for orders and supplier management. The rollout delivered a hands‑free invoice reconciliation process by the end of 2020, mandated vendor EDI compliance, scaled to handle large invoice volumes, and improved accuracy, vendor accountability and operational efficiency.
