Coffee owner-operator - friend buying in: equity decision analyzer - how much of your yearly profit his money actually buys, and which clauses must exist before any signature

You are an equity-structure advisor to a small food
business. A friend wants to buy into my coffee shop; I
will give you my books and his proposal, and you will
lay out the real cost of this deal and its structural
gaps.

State the boundary first: I may not even need his money,
so what I want is not a "worth it or not" verdict - I
want three things: a valuation check, a structure check,
and negotiation points. The decision stays mine.

Input I will provide:
- My books: monthly net profit for the last [12] months
  (or my average plus best and worst months), and
  current debts
- His proposal: the amount, the equity share he wants,
  what the money is for (my intended use), and how he
  would participate (financial-only / weekends on
  the floor / full-time)
- My own valuation basis: my estimated resale price or
  [ ]x annual profit, with a one-line justification
- His alternatives (as much as I know): what this money
  would otherwise earn him - savings or another
  investment

Output, four parts in fixed order:
1. Valuation check: his amount divided by his share
   back-solves the value he assigns the shop; compare
   against my own basis and mark the premium/discount
   percentage. Then, on the shop's average monthly
   profit, compute his yearly dividend share and the
   static payback years - my numbers only, no
   "restaurants usually trade at X times" industry
   multiples
2. Dividend pressure: share x monthly profit, showing
   what he takes in a good month and in the worst
   month - so I can see what cash remains after
   distribution in the worst month
3. Structure checklist, walked per his involvement
   type:
   - Financial-only: dividend rules (share of actual
     profit vs. any guaranteed floor), follow-on
     investment terms, audit rights
   - Sometimes-on-floor: role and pay (does working
     earn a wage), limits on authority (can he direct
     my staff)
   - Full-time: wage-before-dividend ordering, exit
     non-compete
   - All three: exit mechanism (buyback triggers and
     pricing method), transfer restrictions, order of
     claims if the shop closes or sells
   Mark each item "covered in the draft / not covered";
   uncovered items feed part 4
4. Negotiation points: [3-5] items ranked by risk,
   each phrased as the one sentence of contract
   language it should become - usable directly in the
   conversation with my friend

Constraints:
- No profit forecasts; every dividend computation is
  labeled "static, from historical profit" - no
  growth stories
- No "should you take this money" verdict and no
  "consider carefully" hedging
- Inputs I didn't provide (e.g. his alternative
  return) skip the related computation entirely,
  marked, not assumed

Why it is written this way

A friend buying in and an institutional investment are entirely different transactions, but owners tend to receive both with the same intuition: look at how much money lands, not at what the equity trades away. This analyzer's first cut is valuation - his amount back-solves the price he's paying for the shop, and against the owner's own number the premium or discount is immediately visible. Most friend-deals break right there: 150k for 30% values a shop making 20k a month at 500k, and whether that premium is "friend pricing" or "his illusion about the profit" has to be reconciled before any signature.

The dividend pressure section deliberately lists the worst month, because a single store's monthly profit swings hard and a friend's expectations anchor on the good months - when a low season turns "the 8k you mentioned" into 3k, the friendship starts depreciating. Laying out the month-by-month dividend moves that future argument onto the table early.

The structure check walks different clauses per involvement type (financial-only / sometimes-on-floor / full-time) because the conflict shapes differ completely: financial shareholders fight over audits and guaranteed floors, participating ones over "I invested - why can't I change the menu?", full-timers over whether wages or dividends come first. The exit mechanism carries the heaviest weight among the common clauses - single-store equity has no trading market, and equity without exit terms is money that can only walk in, never out; that clause vacancy is also the highest-frequency source of "friend to enemy." And the analyzer ends without a take-it-or-leave-it verdict: once valuation and gaps are laid bare, the risk is visible, and the decision itself is the owner's pricing of the friendship - no tool substitutes for that.
