The Company capitalizes certain internal-use software development costs, consisting primarily of contractor costs and employee salaries and benefits allocated to the software. Capitalization of costs incurred in connection with internally developed software commences when both the preliminary project stage is completed and management has authorized further funding for the project, based on a determination that it is probable the project will be completed and used to perform the function intended. Costs incurred for enhancements that are expected to result in additional functionalities are capitalized in a similar manner. Capitalization of costs ceases no later than the point at which the project is substantially complete and ready for its intended use, at which point amortization of capitalized costs begins. All other costs are expensed as incurred. Costs capitalized in connection with internally developed software were $5,626 and $6,984 for the twelve months ended December 31, 2023 and 2022, respectively.

For the twelve months ended December 31, 2023 and 2022, total amortization expense was $23,533 and $20,438, respectively.
