Cash Flow Template?

Hello,

I'm starting an ecommerce business - and will start selling a decent amount soon. I've setup a basic cash flow statement, although I feel I might as well get it right first time and therefore find something professional.

I don't have money to pay an accountant right now, although I'm just wondering if anyone could direct me to a professional template that I can use to do finances for now?

I'm currently using google docs, so that would be preferable

Thanks,
Oli
