There is no official universal golden list
Searches for seven keys, seven golden rules and the number-one rule produce different lists. The important question is what behaviour a principle encourages. A rule that increases pressure while hiding limitations is not made useful by a memorable title.
Here's seven principles are a working code for owner-led selling. They are not a certification standard or a claim that every successful salesperson follows identical words.
Seven principles in practice
First, understand before recommending. Second, qualify honestly. Third, explain value and limitations clearly. Fourth, check the economics and delivery promise. Fifth, agree a useful next step. Sixth, keep your commitments. Seventh, learn from the outcome, including an appropriate no.
The principles reinforce one another. Understanding without qualification can still lead to unsuitable work. A clear proposal with an impossible date creates a future problem. A friendly relationship without follow-through does not protect the customer experience.
Worked example (illustrative): the deadline you cannot meet
A prospect will buy only if a project starts next week. The seller knows the team is committed for the next fortnight. The tempting response is to promise the date and hope operations finds a way.
A better response explains the available options: a later start, a genuinely smaller first stage if feasible, or a referral where appropriate. The customer may decline. That is not automatically a sales failure. Accepting an unworkable promise could create rework, conflict and damaged trust.
The seller should still investigate whether the deadline is fixed or whether the customer needs one specific output early. Understanding the real requirement can reveal a suitable option without misrepresenting capacity.

Use the informed-decision test
Ask whether the customer understands what they are buying, what it excludes, what they must provide and what happens if conditions change. The ACCC's guidance on misleading claims is relevant when describing benefits and prices. Do not use vague disclaimers to contradict a prominent promise.
An informed customer can compare alternatives and say no. Making those choices possible is not weak selling. It reduces the chance that a sale depends on a misunderstanding.
Keep the handover inside the sale
Before celebrating, confirm that delivery has the agreed scope, timing, assumptions and customer context. Name the person who owns the next contact. A contract or invoice alone may not capture everything the customer believes was promised.
Where the seller has made an exception, record it clearly and obtain the required approval. Do not leave the team to discover a discount, extra task or deadline through a frustrated customer's email.
Learn without rewriting history
After a win or loss, compare what was expected with what happened. Record the customer's stated reason where available and mark other explanations as possible explanations. Avoid treating every win as proof of skill and every loss as a problem with the lead.
The golden-rule question becomes practical: "Did we help the right person make a clear decision and create work we can honour?" Use that alongside commercial measures. It is a more durable standard than closing every opportunity at any cost.
Your next action
Review one won and one lost opportunity against the seven principles. Find one commitment that was unclear and one point where a respectful no would have been appropriate. Write a pre-handover check that prevents the same ambiguity next time.
