HUBSPOT Contract

Hi Everyone,
I contacted Hubspot last November and gave me a deal. They offered an annual subscription for $12000 with 12,000 contacts for the Marketing Professional Hub. They gave me an invoice to be paid by December 30 but my company doesn't want to pay that big and said to me that I need to find a better deal.
Since It has not been paid yet, Is it still possible for me to get out of the deal instead?
Thank you!
