Sume's 5.5% fee in dollars on a $50, $250, $1,000 or $5,000 month

Sume charges the vendor list price × 1.25, then a 5.5% fee on that result. The fee is therefore a percentage of the catalog amount, not of the vendor list. This post shows it in dollars at four monthly sizes, so you can see what it adds to a bill you can already estimate from the catalogs.

Sume prices every job at the vendor list price × 1.25, then adds a 5.5% fee on that result, so $1.00 of list becomes $1.31875 (how the formula works). The tables below show both the catalog price (list × 1.25) and the all-in figure with the fee.

Fee at four spend levels

Back to vendor list

If you only know the vendor list spend, multiply by 1.31875. A $1,000 month of vendor list prices becomes $1,318.75: $1,250.00 after the margin and $68.75 for the fee. See the formula worked on one dollar for the micros arithmetic.

Because the fee is a flat percentage, it does not change which model is cheaper; it scales every line the same. Compare models on catalog price and add the fee once at the end.
