Commitment

What is a commitment?

Also called open commitment, or committed cost.

A commitment is money the production has contractually promised but not yet been invoiced for, most often an open purchase order.

Commitments belong on the cost report because a signed vehicle rental or equipment order is a real cost regardless of whether paperwork has caught up. Tracking open commitments against the purchase order log is what keeps a cost report from quietly understating the picture.

Example

A signed purchase order for $27,000 of vehicles produces no invoice until wrap. It is a real cost from the day it is signed, so it belongs in the commitments column. Leave it out and the report understates the show by $27,000.

Where you'll see it

Common mistake

Leaving open purchase orders off the report until the invoice arrives. The picture then looks under budget by exactly the amount it has already promised to spend.

Related questions

Is a purchase order a cost before the invoice arrives?
Yes. Once approved it is a contractual obligation, so it belongs in the commitments column whether or not the vendor has billed for it yet.
Where do commitments appear on a cost report?
In their own column between actuals and the estimate to complete, sourced from the open balances on the purchase order log.
