If I own a company and provide supplies to someone, and in return they do service work for me,what do I debit?

I should credit my supplies and debit COGS, but then also credit revenue and debit what? Normally I would debit cash or accounts receivable, but I'm not sure that to do in this situation.

yes, debit cash.
not ARs.
cause Debiting those means $ is due you

btw-if biz is poking along, hire a CPA to do this and spend time marketing your services
