Not all funding comes from factoring companies financing invoices. Another funding source is equipment leasing. If a business needs a substantial piece of equipment, one way to deal with the purchase cost is through leasing. Essentially the leasing company will make the purchase and the business pays monthly for use of the equipment. Over time, the equipment is paid for and the business owns it outright. There may be tax benefits to this arrangement so check with your accountant.
There are leasing companies that specialize in various types of equipment and sizes of purchases. Generally, getting a referral from a business associate would be a good place to start.
Having equipment leased in most cases will not affect the ability to secure accounts receivable factoring to keep the cash flow coming in for normal business operations.
