Hello and thank you for the opportunity to assist you. There might be a slight delay between your follow ups and my replies as I am typing out my answer, or taking a quick break. Please remember that this is general information only, not legal advice, and no attorney-client relationship is formed.

This depends on your contract.

If you have a written contract governing the transactions, then the company may only do so if the contract allows. Otherwise, if the contract does not allow to do this, then they cannot, and doing so may be termed a Breach of Contract.

If there is not written contract, then they may since each individual transaction could be seen as a merchant to merchant contract, and simply on this one, they decided to pay a little later.

The problem on verbal contracts is that even if they promised to pay in 60 days verbally - unless you have it in writing - it is very hard to prove that they made this promise in the first place.

I hope this finds you well. Please remember that I do not get credit for my time with you unless the answer is rated/concluded by you; I work very hard to formulate an informative answer for you – please reciprocate my good faith. If you still need information, hit reply so we can chat until you are satisfied. You may always come back to it to ask follow ups on this topic free of charge.
