Question on Forecasting

I have a set of data of orders delivered to customers. For every order we predict a commit date on which the order will be delivered. We are measuring the the performance by comparing te committed date and the actual date.

To know if my predictions are correct can I consider the commit date I predict as a forecast and measure Forecast accuracy (MAD, MAPE, SSE) & Bias(Mean Bias & confidence intervals).

I have this doubt because the above measures are usually used to check the accuracy of a forecasted demand & in this case I'm forecasting/predicting the date by when a certain order will be delivered.

Please let me know your views on this.

Appreicate your help.

Thanks & Best Regards
