Assuming you have the 1099 form for the vendor in question, there are a few ways to pay them:  Check: You can simply write a check from your personal or business account to the vendor. Be sure to include the 1099 form with the payment so they can properly document it.  Electronic Funds Transfer (EFT): Many banks offer this service, which allows you to electronically send money from your account to another. This is usually done through the ACH network and you will need the vendor’s banking information in order to set it up. Again, be sure to include the 1099 form with the payment.  Credit Card: You can also pay vendors with a credit card, but be aware that most cards charge a fee for doing so (usually around 3%). Also, if you are using a personal credit card, you will need to be extra careful to track expenses and make sure they are coded correctly in your accounting system so as not to mix personal and business expenses.  PayPal: PayPal is probably the easiest way to pay vendors online, and many accept this method of payment. There is no fee for using PayPal if you use your bank account or balance; however, there is a fee for using a credit or debit card (2.9% + $0.30 per transaction). As with paying by credit card, if you are using a personal PayPal account, make sure you carefully track expenses and code them correctly
