Government procurement fraud occurs when contractors or companies deceive the government during the bidding or performance of a contract. It involves dishonest practices that lead to the misuse of taxpayer dollars and often result in significant financial losses. Many businesses that contract with the government are honest, but some exploit weaknesses in the procurement process for personal gain. This type of fraud can occur at any stage, from bidding to billing, and it can involve a single individual or a large corporation. Because these cases can be complex, understanding how they occur helps protect both the government and the public. The Mark A. Strauss Law Firm works to expose and stop these fraudulent activities by helping whistleblowers report wrongdoing under the 

False Claims Act.

Government contracts are often large and involve many moving parts, which creates opportunities for unethical behavior. Procurement fraud can take many forms, and recognizing the most common types is key to preventing them.

False Billing and Overcharging

False billing is one of the most frequent types of government procurement fraud. It happens when a contractor bills for work that was never completed or for materials that were never delivered. Overcharging occurs when a company inflates costs, billing the government for more than what was actually spent. These deceptive practices can involve forged documents, false time sheets, or duplicate invoices. Over time, false billing can cost taxpayers millions and weaken public trust in government spending.

Bid Rigging and Collusion

Bid rigging is another serious form of procurement fraud. In these schemes, competitors secretly agree on who will win a government contract before the bidding process even begins. They might take turns submitting the lowest bids or agree to submit intentionally high bids to ensure a specific company wins. This manipulation eliminates fair competition and prevents the government from getting the best value for its money. Collusion between contractors undermines public trust and can lead to substandard work or inflated project costs.

Product Substitution and Defective Products

When contractors provide products or materials that do not meet contract specifications, it’s known as product substitution. These situations happen when people use lower-quality materials instead of the ones required, or provide used parts instead of new ones. This kind of fraud breaks contract rules and can create serious safety risks in important areas like defense, transportation, and healthcare. Delivering defective or substandard products can put lives at risk and damage public infrastructure.

Cost Misrepresentation

Cost misrepresentation happens when contractors lie about their expenses to receive higher payments. This can include inflating labor costs, reporting fake subcontractor expenses, or hiding cost savings that should be returned to the government. Many cost-reimbursement contracts rely on trust and accuracy in financial reporting. When that trust is broken, it leads to waste and abuse of government funds. Detecting cost misrepresentation often requires careful auditing and review of financial records.

Kickbacks and Bribery

Kickbacks and bribery happen when a contractor gives money or favors to a government official to get special treatment. These illegal arrangements distort the procurement process and can result in unqualified companies winning contracts. Even small kickbacks can have major consequences because they compromise fairness and transparency. In some cases, the people involved face criminal charges and heavy fines. Combating this type of fraud requires strong oversight and enforcement of ethical standards.

Government procurement fraud is a serious issue that affects taxpayers, honest businesses, and public confidence. Each type of fraud—from false billing to bribery—diverts funds that could have been used for essential services and programs. Identifying and preventing these schemes is crucial to maintaining integrity in government spending. Law firms that handle whistleblower cases play an important role in uncovering wrongdoing and holding fraudsters accountable. By understanding common types of procurement fraud, individuals and businesses can help ensure that government contracts are fair, open, and honest.
