Ask HN: Help structuring seed round deal terms

We are a 3 member B2B SaaS startup. We have an ARR of $240k and a MRR of $20k. We are in a market that is rapidly growing, have couple of large distribution deals in place and defendable IP. We’ve decided to raise a seed round this fall. We made the first pitch to an investor and he liked it. He also wanted us to provide details on the deal terms. We want to raise $1million. We’ve been focussed on our product and business development that we never thought about funding. We need some pointers on how to structure the deal. Can someone throw few ideas on how the deal should be structured? SAFE or Convertible debt or Equity? Any other deal terms we should include?
