Pay As You Go
We should be able to pay for campaigns as each round of mail piece is generated. If I've created a slow drip campaign (i.e. quarterly letters to a probate list over 2 years) and I have 1000 leads, with 8 letters, it would cost me $7,120 up front! The last of the money "spent" on the campaign wouldn't happen for 2 years, though I'm out all the money today.
