Real Results

Is Time Billed Correctly?

While auditing the billings of a company providing cleaning services, hundreds of overtime hours billed we identified before the appropriate number of straight time hours had been worked. The documentation required to confirm these misbillings was not part of the vendor’s standard invoice packet, so our client was only provided the total number of straight time and overtime hours billed.

A recovery of $180,000 and an amendment to future contracts.

Know What You're Paying For?

For vendors providing project based billings, it is quite common for an annual budget to be assigned to the customer, for all planned charge categories. A real estate management provider with $100M in annual billings, identified discretionary employee bonuses in the labor burden billed to our customer. There was no information on bonus eligibility, and these charges were not listed in the contract.


Our customer was overbilled $1.2 million for these bonuses

Complicated Billing Structure

A contract compliance audit of vendors supplying temporary labor can uncover improperly calculated markups. For example: a supplier was frequently exceeding the contract markup percentages. Multiple markups were defined based on the length of a temporary employee’s service contract, and the vendor was applying the highest potential markup to all service durations.

The vendor overbilled and refunded $88,000 to our customer.
