Overview
A customer walks up with an offer. You have a few seconds to accept, counter, or walk away - and the difference between those three is usually several hundred dollars.
The advisor answers in one line: what they can spend, what your offer is worth against it, and what to counter with. Everything else on the page explains that line.
What a customer can actually spend
Every customer holds a budget ceiling that grows with your rank, but they do not empty it on one transaction. Only a fraction goes into any single deal, which is the number the advisor works from.
That budget is fixed, so your unit price decides the quantity. Ask more per unit and they buy fewer. Because units are whole, the division rounds down and leaves change on the table - which is why two different prices can produce exactly the same total, and why a greedier price sometimes earns less than a modest one.
Set your save rank at the top of the page. Budgets scale with it, and a wrong rank makes every figure here wrong with it.
What raises the price they accept
Quality above their expectations, at 15% per tier. The key word is theirs: a demanding customer expects Premium as a baseline, so delivering Premium earns nothing extra from them while it would be a bonus with someone less fussy. Delivering below their standard costs you the sale rather than the price.
Delivery conditions, at 20%. Curfew and quick delivery each add a fifth, but never together - you cannot deliver inside the hour and after curfew at once. Rain is a separate condition and does stack with either.
The total is capped at 60%. Stacking a big quality jump with curfew and rain does not compound past that, so past a point there is nothing left to gain from waiting for a storm.
Using the advisor
Pick the customer first. Their budget and preferred effects appear straight away - often enough on its own to decide whether the conversation is worth having.
Then pick what you are selling. The recipe sets the product family and the unit price, which together decide whether they will buy at all and how much of it.
Enter their offer as they made it: a price per unit and a quantity. The advisor multiplies the two to see what the deal is worth against their budget, and compares their unit price to yours - that gap is what you are actually negotiating over.
Read the line, go back to the game. The counter-offers below are variants - fill the budget, charge more per unit, or stay conservative when the match is weak.
