Each contract, including the specifications, will have specific requirements for what you need to do each billing cycle to get paid. These may include:
- Billing forms or electronic processing systems, such as Textura
- Notarization of billings
- Certified payroll
- Lien releases
- Other backup for the billing, including invoices if it is a T&M or GMP project
You will need these documents from your company and likely from your subcontractors and key vendors. Make sure that you have the requirements for all these in their terms and conditions.
If you aggressively bill and get approvals for the progress billing amounts, then this contract compliance backup is the last thing that can hold up getting paid.
