Claim against a sole proprieter who transfered business assets with no list of inventory.

I am a pro se defendant. The plaintiff and I entered into a quitclaim agreement wherein the plaintiff took control of a business I owned and all its assets. The wording on the quitclaim states that I must "provide them (plaintiff) all material goods associated with the business." They received a large amount of goods from me as per the terms of the contract. I asked them if they wanted an inventory of all the goods to be transferred and they declined, saying they didn't need one. After the transfer had been made and they took over control of the business and assets, they filed a claim saying I "did not provide ALL the goods associated with the business, and have committed fraud, theft, and breach of contract." I was a sole proprieter, so by law there really is no legal distinction between "my personal belongings" and "belongings associated with the business," or so I have been led to believe. Do they have a claim against me based on my having personal belongings?
