Are You Helpless With A Time & Materials Contract? You probably prefer fixed priceservice contracts, right? In those, if the service requires more time or material than planned, the supplier’s profit is reduced, not yours. Sometimes, a supplier will refuse such risk and will insist onusing a time and materials contract. In a time and materials contract, you pay the supplier for the number of hours actually required to perform the service. So, the supplier has no incentive tominimize the number of hours expended on the service. The less efficient the supplier is, the more money it makes!

Suppliers not quoting fixed prices may charge “list price” for labor. If you are a big company or aresourcing a big project, don’t pay list price. Negotiate a lower labor rate to reduce your total cost. 2. Maximum Number of Labor Hours. Experienced suppliers should be able to estimate the hoursneeded for a job. Negotiate a cap on the number of hours where, if the supplier exceeds that number of hours, you don’t pay for the overage. This avoids the “less efficiency = more money” issue of time andmaterials contracts. 3. Mark-Up on Materials. When billing for a time and materials contract, the supplier usually calculates the materials cost by adding a markup (usually 15 – 35%) onto the pricesit paid. If a supplier paid $1,000 for materials, it will bill you about $1,200. I’ve had success getting suppliers to only charge what they paid for materials, with no markup. 4. Not-To-Exceed Total.The next best thing to a fixed price contract is a time and materials contract with a Not-To-Exceed (NTE) amount. Under this arrangement, the supplier can charge you for its labor and materials up...
