should i keep copies of my business's invoices for tax records?

it's always beneficial to have detailed business records.  there are any number of reasons where you'd need to prove both the types of services you've rendered and the payment history - you've already noted audits (for irs taxes).  other possibilities: whether these records need to be original or electronic might be the topic for another question.
