A $50,000 non-payment case taught me about buyer risk management. A long-time client with a perfect payment record suddenly stopped paying. By the time I engaged a collection agency, the buyer had already closed their company and reopened under a new name. I now: (1) monitor buyer credit regularly, (2) maintain credit insurance for accounts over $20,000, (3) require personal guarantees for new company structures, (4) stop shipment immediately when payment is overdue beyond 30 days.
A quality disaster early in my career taught me the difference between 'sample quality' and 'production quality.' Our samples were perfect — precise dimensions, flawless finish, beautiful packaging. The bulk shipment looked nothing like the sample. Colors were off, tolerances were sloppy, and 15% of units were damaged. I learned to always: (1) request samples from regular production, not specially prepared ones, (2) conduct pre-shipment inspection by a third party, (3) include clear quality specifications in the contract with measurable criteria.
