Monthly minimum

A floor on what you pay, whatever the volume — and sometimes a true-up that bills the gap.

What it means

Two shapes, and they are not the same. A floor says your bill will not go below a number. A true-up says that if your activity priced out below the minimum, the difference gets added as its own line.

What goes wrong

The minimum is applied in a month that already cleared it, so you pay the floor and the activity. Or a true-up is billed on gross activity before credits rather than after. Both look like a single extra line on an invoice with six lines on it.

The arithmetic

Contract · minimum $5,000.00 per month, as a floor.

Activity, priced from the rate card    $6,180.00
Minimum                                $5,000.00

The floor is already cleared. No minimum line is due.

The invoice showed
  Fulfillment activity                 $6,180.00
  Monthly minimum                      $5,000.00
                                      ----------
                                      $11,180.00

Overbilled                             $5,000.00

How to check it

Price the month's activity on its own first. If activity already exceeds the minimum, no minimum line should exist at all.
