Depends on type of business entity you're using.

If it's a sole proprietorship, you can do anything you like.

If it's any other form, receiving money personally will nullify your business. Read up on mingling personal + business money.

And as always, this is a question for you tax preparer.

To be safe, just receive the money as if someone made a payment for goods + services to your business... so... person would write the check, just as if they were buying from your business.
