One of the struggles we faced, and many other businesses face, is when you want to focus on the business, and you view accounting/invoicing as a very tedious task (I hate it!)
For both of these tasks, no one can beat Freshbooks.
One of their Mottos is: “Every customer should look like a Fortune 500 company, based on the image sent by invoices, bills, or other accounting communications, no matter what size the company is.”
You have to realize, that when dealing with a SaaS or just a simple “Service”-based business, people are investing in YOU when they purchase your service.
Perception is reality, don’t forget it.
I owned a Merchant Account (Credit Card Processing) business for over 4 years – they can definitely be a pain. I’d highly recommend First Data but ONLY if what you are doing is not considered “high risk” in any way. If it is, I’d recommend Merrick Bank
Congrats – now you have a fully functional solution with some of the best software vendors in the industry! Get out there and kill it.
