Revenue [Abstract]  
Revenue Revenue
Revenue is recognized based on the transfer of control or our customers' ability to benefit from our services and products in an amount that reflects the consideration we expect to receive in exchange for those services and products. Most of our service and product contracts are short-term in nature. In recognizing revenue for our services and products, we determine the transaction price of purchase orders or contracts with our customers, which may consist of fixed and variable consideration. We also assess our customers' ability and intention to pay, which is based on a variety of factors, including our historical payment experience with, and the financial condition of, our customers. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 20 to 60 days. Other judgments involved in recognizing revenue include an assessment of progress towards completion of performance obligations for certain long-term contracts, which involve estimating total costs to determine our progress towards contract completion and calculating the corresponding amount of revenue to recognize.

Disaggregation of revenue
We disaggregate revenue from contracts with customers into types of services or products, consistent with our two reportable segments, in addition to geographical area. Based on the location of services provided and products sold, 42% and 47% of our consolidated revenue was from the United States for the three months ended March 31, 2024 and 2023, respectively. No other country accounted for more than 10% of our revenue for those periods.
The following table presents information on our disaggregated revenue.

Contract balances
We perform our obligations under contracts with our customers by transferring services and products in exchange for consideration. The timing of our performance often differs from the timing of our customer’s payment, which results in the recognition of receivables and deferred revenue. Deferred revenue represents advance consideration received from customers for contracts where revenue is recognized on future performance of service. Deferred revenue, as well as revenue recognized during the period relating to amounts included as deferred revenue at the beginning of the period, was not material to our condensed consolidated financial statements.

Transaction price allocated to remaining performance obligations
Remaining performance obligations represent firm contracts for which work has not been performed and future revenue recognition is expected. We have elected the practical expedient permitting the exclusion of disclosing remaining performance obligations for contracts that have an original expected duration of one year or less. We have some long-term contracts related to software and integrated project management services such as lump sum turnkey contracts. For software contracts, revenue is generally recognized over the duration of the contract period when the software is considered to be a right to access our intellectual property. For lump sum turnkey projects, we recognize revenue over time using an input method, which requires us to exercise judgment. Revenue allocated to remaining performance obligations for these long-term contracts is not material.

As of March 31, 2024, 32% of our net trade receivables were from customers in the United States and 10% were from customers in Mexico. As of December 31, 2023, 33% of our net trade receivables were from customers in the United States and 9% were from customers in Mexico. Receivables from our primary customer in Mexico accounted for approximately 8% and 6% of our total receivables as of March 31, 2024 and December 31, 2023, respectively. While we have experienced payment delays from our primary customer in Mexico, the amounts are not in dispute and we have not historically had, and we do not expect, any material write-offs due to collectability of receivables from this customer. No country other than the United States or single customer accounted for more than 10% of our net trade receivables at those dates.

We have risk of delayed customer payments and payment defaults associated with customer liquidity issues. We routinely monitor the financial stability of our customers and employ an extensive process to evaluate the collectability of outstanding receivables. This process, which involves judgment and estimates, includes analysis of our customers’ historical time to pay, financial condition and various financial metrics, debt structure, credit ratings, and production profile, as well as political and economic factors in countries of operations and other customer-specific factors.
