Hi Julia

I use a letter of agreement, sent via email - rather than an actual contract. For new VAs: I do NOT suggest doing this. The *only* reason I operate this way is because in a referral-only practice all of my clients are friends and colleagues of one another. I don't work with clients from outside that circle so I remove numerous variables. I also take a substantial deposit on all new clients.
The letter of agreement I send basically states that their reply in the affirmative along with receipt of their deposit equates to an agreement of the terms outlined.
I sign any NDAs etc. digitally and send those back via email as well.
There was one situation where we were asked by the
client to sign a contract and in that case we had him fax it to our fax to email number, printed it out, signed it, scanned it back in, and faxed it back. I've done the same for rental house agreements, etc.
