$5.4M saved managing $650M in annual spend. $2.2M from one sourcing process. I run procurement & purchasing operations for companies that grew faster than their back office. I'm not a firm & I'm not software. I'm a senior operator you embed in your purchasing function on a monthly retainer: mapping your buying processes, running purchasing day to day, building supplier workflows, & automating the repetitive work with AI agents. WHAT I TAKE OFF YOUR PLATE: - Purchasing operations: PO process, reorder management, supplier follow-up, receiving & reconciliation - Strategic sourcing & supplier negotiation (the 7-step process behind the $2.2M win) - Inventory management: demand forecasting, reorder points, excess & obsolete cleanup - Spend analysis that finds the savings hiding in your data - Process mapping, SOPs, buyer training & hiring readiness - AI & automation layered on top of all of it, so the function runs without adding headcount TRACK RECORD: - $5.4M annual savings via supplier transition & negotiation - $2.2M category savings from a 7-step strategic sourcing process - $6.7M over 5 years from a source-to-pay platform deployment - 98% inventory accuracy & $500K first-year savings - 20-day improvement in cash conversion cycle HOW WE START: Every engagement opens with a paid baseline assessment of your purchasing operation: what's working, what's leaking money, & a prioritized 90-day plan. If I can't find savings well beyond my fee, I'll tell you & hand you the plan anyway. Ongoing work runs as a monthly retainer. BEST FIT: e-commerce, retail, distribution & light manufacturing businesses with $5M+ in annual purchasing spend & a procurement function that hasn't kept up with growth.
