We capitalize certain software development costs incurred in connection with developing or obtaining computer software for internal use when both the preliminary project stage is completed and it is probable that the software will be used as intended. Capitalized software costs include (i) external direct costs of materials and services utilized in developing computer software, and (ii) compensation and related benefits for employees who are directly associated with the software projects. Capitalized software costs are amortized on a straight-line basis when placed into service over the estimated useful life of the software, generally averaging three years. We capitalized software development costs of $440,000 for the nine months ended September 30, 2023.
