Hello.. I am the owner of a recently started furniture business. Marketing and promotions are going well and business is starting to do well. There are a few concerns though,especially with the invoices. Some errors keep creeping up, like duplicate billing and all. I am thinking about hiring a third party logistics audit specialist to prevent such things. Can someone give more tips to prevent invoice errors or other such issues that can hinder our business success? Any kind of advise will be really helpful. Thanks!
