Midwest Industries Ltd. produces several custom-made attachments to heavy equipment in bulk.

The company has several departments, and is unsure of which costing system to use to :

Activity-based costing, job costing & process costing.

Also, should they use actual or budgeted costs.

The typical job for Midwest is large in nature and customizable.

Costs are put as either direct or indirect/overhead or period within the specific manufacturing facility. The company uses FIFO for their direct materials.

What is the best costing system they could use? Should they use actual or budgeted costs?
