Why You Should Regularly Review Your Supplier Material Markups

Many trades businesses fall into the trap of using a 'set and forget' markup strategy for materials. When you apply the same percentage to every invoice regardless of your fluctuating supplier costs, you often end up eroding your own net profit without realizing it. Taking time to review your supplier invoices monthly ensures your business maintains healthy margins.

Rising inflation means your core costs for lumber, copper, and specialized hardware change constantly. If your system isn't reflecting these increases, you are effectively paying the difference out of your own pocket. By auditing your markups every quarter, you ensure that your pricing remains competitive while still covering the hidden costs of administration and logistics.

A simple way to protect your bottom line is to implement a tiered markup system based on the effort required to source the items. Items that take significant time to order, collect, and transport should carry a higher percentage than off-the-shelf goods. This granular approach ensures you are adequately compensated for the time you spend away from the tools.

Finally, communicate clearly with your clients about these material adjustments if your contract allows for it. Most project owners understand that supply chain costs fluctuate, and being transparent builds trust. When you manage your markups effectively, you create a more resilient business that can survive market volatility while continuing to grow your profit margins.
