Conclusion
Construction companies typically overbill at the start of a project. The reason is simple, you want the cash in hand to complete your project. Companies overbill to help offset the negative cash flow due to slow payments (a common norm in the construction industry, unfortunately).
It's always preferable to obtain your cash sooner rather than later! As long as you know exactly the amount that has been overbilled on the job, and has good practices to manage the cash to cover the period towards the end of the project, then you are doing great! (though large and constant overbilling can cause many issues which we won't mention here.)
Instead, from now until the end, we will show you why underbilling is never- a good thing!
Underbilling is truly a problem because when a project is underbilled, you are submitting invoices for less money than you have actually earned.
From the typical cash-is-king perspective in the construction industry, underbilling can have a significant negative impact on the cash flow and eat into your profit.

These techniques are provided by the Construction Financial Management Association.
1. Follow Contract Documents:
Submit billing in accordance with the contract documents.
The process usually requires a Pencil Draw or Draft review by the owners’ representatives to verify the billing is for work in place.
2. Submit Schedule of Values:
Before any construction starts, submit a schedule of values.
The schedule should be reviewed and approved by the client’s team, owners, architects, and owner representatives.
3. Monitor Pencil Draw:
The contractor’s team should monitor the Pencil Draw to ensure it is moving through the proper channels.
Determine early on if any changes are needed.
4. Submit Formal Billing:
Once the Pencil Draw is approved, submit a formal billing.
5. Ensure Payment Process:
The project team should ensure the billing is moving through the client's payment process and not getting hung up on someone’s desk.
Underbilling can have a significant negative impact on cash flow in construction projects and profitability. It's crucial to implement sound billing techniques and regularly review work-in-progress schedules to prevent underbilling.
