if the invoice was issued before the S-corp was dissolved then I would agree with @tagteam. if the S-Corp's final return was filed, then you would probably need to amend it. this would be so you don't pay the self-employment tax on the income. if issued after the dissolution, but the goods or services were delivered before this, I think S-Corp reporting would be proper. if the goods or services were delivered by you after dissolution then Schedule C reporting would be proper because of the self-employment tax liability.
after saying all this, if you're willing to pay the self-employment tax on the income, even though the income could be reported on the S-Corp, the IRS should have no objections.
