MA was going to be quite a bit more expensive. I did the transaction through Stripe and they use Delaware.

Since my business is in MA it doesn't matter where my LLC is, I would have had to pay registration fee for "Foreign LLC" in MA to stay legal. That is in addition to fees I would have paid to DE. Not sure if MA is so unique, but I don't think it is.

Situations have changed in tech so I'll probably keep my LLC for a while but when things come up for renewal probably no reason to. Associated with another company and not beating bushes for big time-consuming contracts.
