Payment Terms for Albums

I am wondering how other wedding photographers handle payment terms

for albums. I just booked a wedding and they have decided they want

an album as well and have paid 50% on the wedding album included

with their retainer fee. Do you require the remainder due for the

album with the final payment for the wedding photography, upon

design approval or when the album is delivered? And also do you

have an seperate agreements for albums? I was thinking a signed

letter approving the album design might work. This will be my first

album so I am really excited:)

I get paid the balanace the day of the wedding or a day before. they will get the album when it is done.

All my packages contain albums. $400 down to reserve the day, 1/2 of the ballance due 3 weeks prior to the wedding, and the rest due when they pick up the proof books. So, I have the album to hold out on if their last check bounces. Then, if they order any additional prints or parent albums, payment is due when they place the order. I make sure the check clears before they may have their final prints.
