Now it's easy and affordable to acquire the products you need without depleting your cash or borrowing from the bank. By taking advantage of equipment leasing (minimum purchase $5,000), you have a cost-effective way to obtain new pro photo, video, audio, computer, and post-production equipment at a price you can afford. Leasing is available only for commercial, professional, and not-for-profit organizations — retail customers or month-to-month rentals are not eligible. Transactions are originated through independent lessors. The leasing option is one more reason that A & D Drilling Supply Corp. is the "Professional's Source."
Eligibility Criteria for Leasing
You must be a commercial, corporate or professional customer, or a government, educational or non-profit organization (hobbyists, students or consumers are not eligible).
Start-up businesses are now eligible for financing, subject to credit approval.
Your purchase must be at least $5,000, and you must be willing to enter into a non-cancelable lease for a minimum of 2 years (month-to-month rentals are not eligible).
You and your business must have sufficiently strong credit to qualify.
In most cases, you must provide a personal guarantee for your business’ lease obligation.
You may be located either in the US or Canada, and must have an IRS or CRA tax identification number (please note, approval standards for Canadian businesses are more rigorous than US businesses.)
