When it comes to municipal infrastructure projects the largest financial drain isn’t material cost — it’s payment inefficiency.
Public agencies invest in maintaining and modernizing vital sectors, relying on construction firms for project delivery. But when those municipal agencies cannot process payments in an organized and timely manner, the entire system faces immediate and staggering consequences.
It’s a costly pattern that taxes citizens, deters quality contractors from bidding on jobs — and undermines responsible stewardship of public funds and the trust the public requires.

The Direct Cost of Penalties and Fees
When administrative teams struggle to manage complex projects — often due to a combination of local, federal, and operational challenges — payment deadlines can begin to collapse.
Delays like these are some of the reasons why states protect contractors by instituting prompt payment laws. The Louisiana statute is set at 45 days, with interest charged at 0.5% accumulated daily thereafter. Without modern and auditable invoicing workflows mandatory financial liabilities are inevitable.
Even a $600,000 invoice adds up. Instead of delivering in 45 days, the state of Louisiana could charge 0.5% on the amount owed. That’s $3,400 a day. At one point we paid over a million dollars to a particular contract over the last few years. (Chap Munger, SWNBO)

These overwhelming fees represent a clear operational failure. They directly reduce the budget available for essential infrastructure burdening the taxpayer financially and operationally.
The Hidden Cost in Contractor Bids
When agencies are slow to payout, contractors are essentially forced into a financing position as an unauthorized high-cost lender using their 10% line of credit to float the job. The result is amplified estimates with "insane" prices and overhead charges spread across the bid.
This systemic failure to pay on time is a structural and strategic flaw. By forcing contractors to act as banks, the government agency has no choice but to pay an inflated hidden tax. Doing so exposes a willful failure to uphold its fiscal duty to ensure every public dollar is spent efficiently.
The Strategic Cost of Deterring Qualified Competition
As reputation erodes so does the pool of qualified contractors willing to work with an agency. This leaves them little option but to pinball between various inefficient work styles.
This disparity can result in significantly different project outcomes, particularly when one contractor is aggressively pursuing payments through legal action, while another is more relaxed about submitting invoices.
Agencies with a reputation for payment delays may deter the most efficient and fiscally responsible firms. These less competitive bidding cycles compromise project quality and increase taxpayer cost—a waste on both fronts.

The Path Forward
Antiquated processes create mandatory penalties, inflate costs in a range of ways, and drive away top competition. Rectifying this systemic flaw requires clear direction from leadership and the understanding that there will be bumps along the road — and a large learning curve.
Doing nothing is also a choice. There's a lot more risk involved with that than the risk of moving forward with the best technology available.

By adopting digital solutions for invoicing, municipal agencies can reclaim their standing as responsible financial stewards. This way, they can optimize public budgets through a transparent and accountable single source of truth for centralized information. The result is less costly, taxpayer-friendly projects that are completed on time.
