Compression rentals – The Company generates revenue from renting compressors to our customers. Our rental contracts typically range from one to 36 months. Our revenue is recognized over time, with equal monthly payments over the term of the contract. After the terms of the contract have expired, a customer may renew their contract or continue renting on a monthly basis thereafter.
Deferred revenue – For compressor rental revenue, customers are billed monthly in advance of the month for which the unit is rented. Revenues from equipment sales are billed on an agreed upon schedule, with revenue not being considered earned until the unit has been delivered. Payments received in advance of meeting the above revenue recognition criteria are recorded as “Deferred revenue” on the balance sheets. Deferred revenue was $38,394, $1,273,776 and $812,770 as of January 1, 2023, December 31, 2023 and June 30, 2024, respectively.
Contract costs – During the six months ended June 30, 2024 and 2023, the Company recognized an other non-current asset totaling $1,706,568 and $1,179,747, respectively, for the incremental costs of obtaining the contract arising from the sales commissions to employees because the Company expects to recover those costs through future fees. The Company amortizes the asset over one to three years because the asset relates to the services transferred to the customer during the contract term. During the six months ended June 30, 2024 and 2023, the Company amortized $862,807 and $418,757 respectively, related to sales commissions.
Cash and cash equivalents – We consider all highly-liquid instruments purchased with an original maturity of three months or less to be cash equivalents. We maintain cash in bank deposits with a major financial institution. These accounts, at times, may exceed federally insured limits. Deposits in the United States currently are guaranteed by the Federal Deposit Insurance Corporation up to $250,000. We monitor the financial condition of the financial institution and have not experienced any losses on such accounts.
Concentration of credit risk – Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents and accounts receivable.
Virtually all of our accounts receivable are from customers of varying sizes in the oil and natural gas industry. Two customers accounted for 58% of accounts receivable at June 30, 2024. Three customers accounted for 48% of revenues for the six months ended June 30, 2024. Two customers accounted for 60% of accounts receivable at December 31, 2023. Three customers accounted for 51% of revenues for the six months ended June 30, 2023. Although diversified among many companies, collectability is dependent on the financial condition of each individual company as well as the general economic conditions of the industry. We review the financial condition of customers prior to extending credit and generally do not require collateral in support of our trade receivables.
Accounts receivable are stated at the historical carrying amount net of an allowance for credit losses. The allowance for credit losses is estimated by considering specific customer collection issues, the aging of accounts receivable, supplementary customer data, and future estimated losses in relation to revenues for the year. Accounts receivable are written off only when management has exhausted all efforts to collect such receivables, including efforts of third-party collection agencies. As of June 30, 2024 and December 31, 2023, the Company determined no allowance was deemed necessary. Accounts receivable under revenue contracts was $4,874,643, $8,374,076 and $13,822,465 as of January 1, 2023, December 31, 2023 and June 30, 2024 respectively.
