$1,800 per month is $21,600 per year. $64,000 put in the bank or invested without risk, gives you, very optimistically, $6,400 per year ⇒ if you think they will keep using this for years, that $64,000 is too low by at least a factor of 3. Also, if AWS becomes more expensive, or they start to use the product more, you can increase pricing, but if you took a one time payment, that’s all you got. I would think you need to ask at least $500,000, and probably something closer to a million. That gives you money to spend on putting the source in escrow, which, if they really are a big company, they should want, and also gives you money to talk to a contract lawyer (e.g. about the feasibility of your idea ”if I release an update after that I will charge for it”) and an accountant about this deal. They may not want to pay that much, but they shouldn’t be surprised, either, if you explain to them what extra costs you have to make. Disclaimer: don’t take my word for it. |
