This is about a construction company that gets estimates from subcontractors. For example, the a/c guy gives an estimate for $100,000. Then, when we approve and he starts the job, he does the roughing only, which let’s say is 50%, and we have to pay $50,000. As construction advances, we reach the finishing stage, when the subcontractor (a/c guy) comes back and does the finishing - he puts in the condensers and thermostats. That’s when he sends a final invoice. Sometimes, it’s in 2 parts, sometimes in 4. I need to be able to enter the estimate amount and do progress billing according to where we’re up to. I need to be able to run reports to see how much was already billed and how much is outstanding, as well as at what stage we’re at.
