When it comes down to payment, I have several points I make in a contract.
1: Non-commercial (i.e. weddings and product) must have 50% down, and full payment must be made before deliver of any proofs, period!
2: Any proofs delivered will have a rider attached in the contract specifying that any proofs not returned will be charged at a rate of $15 per image. (If on a CD with 150 images, that’s $2250.Regardless if the images would have been ordered or not.) Believe it when they get the proofs back to me.
3: Time frame is 14 days form deliver of proofs for their return.
4: All of the above is in the contract they sign, and I VERY carefully have them read and go over the contract BEFORE they sign. This way they cannot say they were scammed.
They also get a copy of the contract. (I make three copies for weddings. One for me, one for the bride, one for the groom.)
5: For commercial, a time frame of deliver is spelled out very specifically because of the corporate climate. (It is very diff.) Payment is made in full at time of first delivery.
