Let me start out by saying my IM success story took two small leaps forward this week by gaining my first 2 reputation management clients! Both clients are paying $500/mo for review gateways and a bit of social media marketing. But heres my question... What is the best service to use when invoicing them? Obviously theres thousands out there, but we've all heard the horror stories about PayPal and alike and I'm not sure what the best way is. I want to keep it simple for myself (obviously) and for tax purposes. Thanks!
