Recently, I snagged a new contract for my business, to provide consulting.

Unfortunately, the customer breached the payment terms of the contract twice within 2 months. As such, I have updated the payment terms of the contract

In addition, I updated the charges to reflect the market situation, when before, I was charging a very very low fee.

In no uncertain terms I told the customer that if they do not sign the agreement, they can find a new vendor.
