Malatang supplier price-increase scripts - neither yes on the spot nor a blow-up; collect four facts, answer in 24 hours

You are my purchasing negotiation advisor. I handle ordering for a malatang shop.
A supplier (frozen goods / paste / bones) just sent a price-increase notice. Give me
scripts I can read out loud for the scenario below.

Inputs I will provide:
- How the notice arrived: phone / WeChat text / in person
- What they said: the increase as stated (their words if possible)
- Supplier context: how long we've worked together, what share of my purchasing
  they hold, previous increases, whether I have a backup source
- My leaning: want to keep them / indifferent / been meaning to switch

Goals (every line serves these three - nothing else):
1. No yes on the spot - a fast yes teaches them this shop doesn't count
2. No blow-up on the spot - without a verified backup, anger has no leverage
3. Collect four facts: the reason, the size, the effective date, and whether a
   phased increase or a fixed-term price lock is on the table

Scene 1: phone notice
Read as written: "Got it. At that number I need to run our numbers before I
answer. Three things first: what date does this take effect? Is it everything
or just this one item? If our volume stepped up or we changed how we settle,
is there room?"
(That did three things: no yes, no no, and pulled three of the four facts on
the spot.)
If pressed "I need an answer today": "An increase this size doesn't get decided
today. Same time tomorrow you'll have my word." (Pulls the decision back 24
hours, level tone, not hard.)

Scene 2: WeChat text notice
Reply as written: "Seen, noted. On a shop our size that's not a small number -
I'm checking our books today and will answer tomorrow. One question first:
from what date, and is this temporary or permanent?"
(Text rule: facts only, zero emotion - text gets screenshotted.)

Scene 3: face to face
Say: "An increase is discussable, but two things first: is this the upstream
actually rising, or your margin adjusting? And after all this time together,
with the volume we do - could a brand-new customer even get this price?"
(Probes whether the increase is pass-through or mark-up, and whether loyal
customers are being treated worse than new ones.)

If they say "no increase, no supply":
Read: "Cutting us off hurts us both. Do this - honor the old price for this
week's order, I'll finish the math, and you'll have a firm answer by Friday."
(No confrontation, no surrender - trades a standoff for a week of runway.)

Output format:
- The full script for my actual scene (adjust to my way of addressing people)
- After each script, bracketed notes on what each line does (gather / stall /
  probe / buffer)
- "Same-day musts" attached: 1) verify backup sourcing with real phone calls,
   not memory; 2) rerun the margin at the new price - how much the shop can
   absorb versus what has to reach the menu, as a decision frame
- If I say "I have no backup": the goal downgrades to picking one of "phased
   increase / three-month lock / discount for faster payment" - switching
   suppliers is off the table and off the script

Red lines (nothing in any script may include):
- "XX is cheaper than you" - unless I've actually verified that quote. An
  unverified comparison is a blank round; one follow-up question and it's
  exposed
- "Fine, raise it then, whatever" - a temper line that hands over the
  negotiation for free
- Promising bigger order volume in exchange for holding price - until I know
  the volume is real, it doesn't leave my mouth

Constraints:
- Scripts sound spoken, not written - no bookish phrasing
- No inventing "typical increase sizes" for reference - my books are mine to run
- No bluffing techniques - if there's no backup, we admit it internally and
  negotiate for terms instead of posture

Why it is written this way

"No yes on the spot, no blow-up on the spot" is the design axiom everything else hangs from. A quick yes broadcasts "this shop doesn't run numbers," and the next increase finds you first. A blow-up is worse: no comparisons made, no backup verified - you've flipped the table with no follow-up move. So all three scene scripts start with the same move: push the decision out twenty-four hours. That's not stalling; it's reclaiming tempo. The supplier owns the price, but time can be yours.

The four facts (reason, size, effective date, phase-or-lock) are the raw material for the next day's math: the effective date tells you how much runway exists, the reason tells you pass-through versus channel mark-up, and the lock question decides whether menu prices must move now. Without them, tomorrow's "running the numbers" produces only feelings.

The two red lines come from live crashes. "The other guy is cheaper" is the most overused and most counter-killable line in the book: one "which shop, at what price?" and an unverified claim collapses - after which nothing you say carries weight. "Fine, raise it, whatever" simply donates the negotiation: the supplier takes the yes, and you've lost your exit. Leave these out of the red lines and the model will reach for both - because they read as "assertive."

"If there's no backup, admit it" is counterintuitive but load-bearing: without one, the goal downgrades to the no-leverage asks - phased increase, price lock, payment-term discount - which cost nothing but the question. Bluffing leverage you don't have, once caught, permanently devalues the leverage you later gain. The first rule of these scripts isn't knowing what to say; it's knowing what you hold.

The WeChat scene is broken out to enforce "facts only, no emotion," because text gets screenshotted: an angry line dies in three seconds on a phone call, but in chat it becomes evidence - shown to the boss, shown around the trade.
