Can I change my mind about wind-down and pursue a sale instead partway through closing up?

Often yes, but how much room you have depends on how far the wind-down has actually progressed. If you've begun winding down but haven't yet terminated key contracts, let go of essential staff, sold off core assets, or filed to dissolve the corporation, switching to a sale is usually still realistic — the business simply needs to still exist, functionally, for someone to buy it as a going concern.

The nuance is that some wind-down steps are hard to reverse. Once material contracts have been terminated, key employees have left, or assets have been sold individually to different buyers, what's left may no longer be sellable as a single business — you may end up back to selling individual pieces rather than a going concern, which typically realizes less value overall. The further wind-down has progressed, the more what remains looks like a liquidation, not a business.

If you're reconsidering, the priority is getting a fast, honest assessment of exactly what's still intact — which contracts, staff, and assets remain — before committing further to either path. A business lawyer can help you understand quickly whether a sale is still realistically on the table or whether the wind-down has already gone too far to reverse.
