## When to use "verb + ed" not for the past but for the future?

I get always confused with the possibility to use verb + ed for the future. The text I'm writing brings the same problem and I'm not sure if I do a mistake if I write:

"Once we receive and review it, we will confirm your order by e-mail."

rather than

"Once we received and reviewed it, we will confirm your order by e-mail."

Which one is correct - can anyone please explain me the rule of how to use verb+ed in this case?
