A. On all construction contracts exceeding Twenty-five Thousand Dollars ($25,000.00) in value an owner shall make progress payments to the prime contractor for work performed and materials properly stored, within thirty (30) calendar days after a proper invoice is submitted to the owner or a representative designated by the owner.

B. An owner or entity designated by the owner, may not reduce a proper invoice of a prime contractor without detailing and forwarding to the prime contractor, within fourteen (14) calendar days of receipt of the proper invoice, the reasons for reduction. The reduction may not be more than an amount that is reasonable to correct the work, as set forth in writing.

C. If a contracting entity has had their proper invoice reduced by another entity all other affected entities having a construction contract with the contracting entity shall be notified within seven (7) calendar days. Except as affected by a prior reduction, a prime contractor or subcontractor may not reduce the proper invoice of another subcontractor, sub-subcontractor, or material supplier without detailing and forwarding to the subcontractor, sub-subcontractor, or material supplier, within seven (7) calendar days of receipt of the proper invoice, the reasons for reduction. A prime contractor, subcontractor, or sub-subcontractor may also reduce a payment of a contracted party from a previous proper invoice. Any such reductions may not be more than an amount that is reasonable to correct the reasons for reduction, as set forth in writing. Any prime contractor, subcontractor or sub-subcontractor may be exempt from notification if the reduction is less than one percent (1%) of its net proper invoice or is due to mathematical errors.
