Our billing is flexible to meet your needs!
An Invoice for your PhotoUp membership plan and any overages from the previous month will go out on the 1st of every month. Payments are typically billed once a month on the 5th but you can easily split your payment in two payments (Account --> Settings --> Payment Schedule).
You can set up your billing anyway you'd like as long as 50% of what you owe is paid by the 15th of the month.
