The prompt
--- name: price-rise-letter description: Works out who to tell about a price rise and when, then writes the letter that explains it without apologising, plus a version for customers who push back. --- # Put your prices up and keep the customers You give your current prices, the new ones, and a list of who is on what. You get back the order to tell people in, the dates, the letter, and a second letter for the ones who argue. ## What it does 1. **Put a number on the gap before writing a word:** list every customer, what they pay now, what they would pay at the new price, and the yearly difference. Corey Haines's marketing skills library makes the case with arithmetic: a customer paying $50 a month who should be at $250 is a $2,400 a year gap, subsidised indefinitely. If the total gap across the base is smaller than the revenue you would risk losing, say so and stop. That is a real answer. 2. **Read the contract before deciding anything, because it sets what you are allowed to do:** Schedule 2 of the Consumer Rights Act 2015 lists terms that may be unfair. Paragraph 11 covers a term "enabling the trader to alter the terms of the contract unilaterally without a valid reason which is specified in the contract". Paragraph 15 covers a term "permitting a trader to increase the price of goods, digital content or services without giving the consumer the right to cancel the contract". So check two things: does the contract state a reason the price can change, and does the customer get a way out. If the answer to either is no, the rise waits for renewal for those customers, and that goes in the plan. 3. **Raise it on new customers first and watch what happens:** put the new price on the website and on new quotes only, and leave every existing account alone for one full sales cycle. New buyers have no anchor and no relationship at stake, so they give a clean read on whether the market takes the number before you touch a single existing customer. If new sales stall at the new price, the plan stops here. 4. **Sort the customers into three named groups, because they do not all get told the same thing on the same day:** group A is the first wave, 5 to 10 per cent of existing customers, chosen as the ones paying furthest below the new price with the lowest support burden. Group B is everyone else on a rolling arrangement, told in staggered waves after group A has been through a full billing cycle without a rush of cancellations. Group C is anyone inside a fixed term with no valid reason clause, who is told at renewal and not before. Name the customers in each group. Do not describe the groups in the abstract. 5. **Set the date, then count backwards from it:** announce a rise 3 to 6 months before it takes effect, which is the delayed increase approach in the marketing skills pricing skill. Business Companion, the Chartered Trading Standards Institute service, is blunter about the direction of travel: a fair variation term must "require you to give plenty of notice" and give "the right to exit the contract without being left worse off". Whatever notice period the contract itself states is a floor, never the target. Write the announcement date, the effective date, and the date of the first invoice at the new price as three separate dates in the plan. 6. **Write the letter in this exact order, and no other:** one line saying the price is changing and when. The old figure and the new figure side by side, for that customer, in pounds and pence, not a percentage. The date of their first invoice at the new price. Two or three specific things that have improved since the last price was set, named, not "continued investment". What they need to do, which is usually nothing. Who to reply to. No apology, no "unfortunately", no rising costs as the only reason given, and no burying the figure under three paragraphs of gratitude. 7. **Write a second, different letter for the ones who push back, and decide the concession before anyone asks:** pick one, and only one, of these to offer: lock the old price in exchange for switching to annual payment, an extended grace period at the old rate, or a one-off credit. The offers skill in the same library frames what the argument is really about: value is the dream outcome and the likelihood of reaching it, divided by the time and the effort it costs them, and "price is the comparison, not the value". So the reply argues the outcome they get, not the cost you carry. Then set a floor: the price below which you let the customer leave, written down before the first phone call. 8. **Give the next rise a rule, so this is the last time it is a drama:** Business Companion notes that fairness "is more likely to be achieved if you use an external index to set the new price", giving the Consumer Price Index as its example. Draft index linked wording plus an annual review date for new contracts, and hand it to the owner as a draft clause for their solicitor, not as a finished term. ## Then it checks 1. Every customer on the list appears in exactly one of group A, group B or group C, and group A is between 5 and 10 per cent of the existing base. Count them, do not estimate. 2. The letter names the actual old figure and the actual new figure for that customer, and the actual date, with no placeholder text and no percentage standing in for a number. 3. The words "sorry", "unfortunately", "apologise" and "we have had no choice" appear nowhere in the letter, and the new price appears within the first three sentences. 4. Every improvement claimed in the letter is one the owner confirmed, and each one is specific enough that a customer could check it. 5. No customer inside a fixed term is raised earlier than the contract allows, and every group has an announcement date, an effective date, and a gap between them of at least the contract's own stated notice period. 6. The pushback letter offers exactly one concession and states a walk away price, and the two letters are genuinely different documents, not the same text with a softer opening. Any check fails: name it, redo that step once. Failed twice: say what is wrong and stop. ## Rules - Public information only. - Never invent a fact, a number or a quote. - Never invent a customer's current price, contract end date or notice period. If one is missing, name the customer, say what is missing, and leave that customer out of the plan rather than guessing. - Never backdate a rise or apply it to an invoice already issued. The new price starts on the date in the letter and not before. - Never send anything. This produces drafts for the owner to read, approve and send themselves. - This prepares a commercial document. It is not legal advice. Any variation clause, index linked term or cancellation wording must be checked by a solicitor before it goes into a contract, and a subscription business should also ask its adviser about the subscription contract rules in Part 4 of the Digital Markets, Competition and Consumers Act 2024, which had not yet come into force when this skill was written. ## Built from - coreyhaines31/marketingskills, pricing skill, https://github.com/coreyhaines31/marketingskills/blob/main/skills/pricing/SKILL.md, 47,986 stars: its "Rollout Methodology" section supplies the test on new customers first sequence in step 3, the $50 versus $250 gap arithmetic in step 1, the 5 to 10 per cent first wave in step 4, the announce 3 to 6 months out timing in step 5, and the point that grandfathering should be a transition and not a permanent exemption. - coreyhaines31/marketingskills, offers skill, https://github.com/coreyhaines31/marketingskills/blob/main/skills/offers/SKILL.md, 47,986 stars: the pushback letter in step 7 uses its value equation, dream outcome and perceived likelihood over time delay and effort, and its line that price is the comparison rather than the value, which is why the reply argues the outcome instead of the cost. - phuryn/pm-skills, pricing-strategy skill, https://github.com/phuryn/pm-skills/blob/main/pm-product-strategy/skills/pricing-strategy/SKILL.md, 26,086 stars: its recommendation output ends with key assumptions paired with how to test them and risks paired with mitigations, which is the shape of the wave plan in step 4 and the walk away price in step 7. - Consumer Rights Act 2015, Schedule 2, https://www.legislation.gov.uk/ukpga/2015/15/schedule/2, read 7 September 2026: paragraphs 11 and 15 are quoted in step 2 and are the reason the contract is read before the plan is built. - Business Companion, Chartered Trading Standards Institute, https://www.businesscompanion.info/focus/holiday-parks/part-1-contract-law-and-unfair-terms, read 7 September 2026: the notice and exit wording in step 5, the Consumer Price Index point in step 8, and its requirement that the reasons for a change and the method of calculating it be set out before the contract is entered into.

coreyhaines31/marketingskills, the pricing skill
https://github.com/coreyhaines31/marketingskills/blob/main/skills/pricing/SKILL.md (repository: 47,986 stars)
A free, MIT licensed library of marketing skills for AI agents, built by Corey Haines of Conversion Factory. The pricing skill is version 2.1.1 and covers packaging, value metrics, willingness to pay and price changes. What was read in full was its "When to Raise Prices" and "Rollout Methodology" sections.
Four decisions in the skill come straight from it. First, step 3, raise the price on new signups only and watch conversion before touching an existing account, because new customers have no anchor and no relationship at stake. Second, step 4, move 5 to 10 per cent of existing customers first and watch a full cycle before expanding in staggered waves, which is where the group A, B and C split came from. Third, step 5, its "Delayed increase" strategy of announcing 3 to 6 months out. Fourth, step 1, its worked example that a customer paying $50 a month who should be at $250 is a $2,400 a year gap, which is the reason the skill starts by making the owner add up the gap rather than starting with the letter. Its warning against reflexive permanent grandfathering is why group C in step 4 is defined as a delay to renewal rather than an exemption.
coreyhaines31/marketingskills, the offers skill
https://github.com/coreyhaines31/marketingskills/blob/main/skills/offers/SKILL.md (repository: 47,986 stars)
Version 1.0.1 of the same library, about the thing you actually sell rather than the price on it. Its core claim is that most requests to lower a price are really requests to raise the value, and it sets out the value equation: dream outcome multiplied by perceived likelihood of achievement, divided by time delay multiplied by effort and sacrifice.
Step 7, the letter for customers who push back, is built on that. The line taken from it, "price is the comparison, not the value", is why the reply is told to argue the outcome the customer gets rather than the costs the business is carrying. The skill's anatomy of a complete offer, which lists guarantee and payment structure as separate components, is why step 7 forces exactly one named concession, chosen in advance, rather than an open negotiation.
phuryn/pm-skills, the pricing-strategy skill
https://github.com/phuryn/pm-skills/blob/main/pm-product-strategy/skills/pricing-strategy/SKILL.md (repository: 26,086 stars)
A large product management skills marketplace, 68 skills across 9 plugins, designed for Claude Code. The pricing-strategy skill sits in the pm-product-strategy plugin and covers pricing models, competitive analysis, willingness to pay and price elasticity.
Two things were taken. Its output template ends with key assumptions each paired with how to test them, and risks each paired with a mitigation. That pairing is the shape of the wave plan in step 4 and of the walk away price in step 7: every decision in the plan carries the test or the limit that goes with it. Its instruction to read the user's own files, competitor pricing and usage data, before asking questions is why step 1 makes the owner produce a customer by customer list first. Its price sensitivity section was deliberately not used: Van Westendorp survey work is beyond a small business raising prices on an existing customer base.
Consumer Rights Act 2015, Schedule 2
https://www.legislation.gov.uk/ukpga/2015/15/schedule/2 (primary legislation, read on legislation.gov.uk)
Schedule 2 is the list of consumer contract terms that may be regarded as unfair. Two paragraphs were read and are quoted in the skill. Paragraph 11 covers a term "enabling the trader to alter the terms of the contract unilaterally without a valid reason which is specified in the contract". Paragraph 15 covers a term "permitting a trader to increase the price of goods, digital content or services without giving the consumer the right to cancel the contract if the final price is too high in relation to the price agreed when the contract was concluded".
This is the whole reason step 2 exists and comes before the plan rather than after it. A price rise on an existing consumer contract is not only a commercial decision, and the two questions the skill asks, is there a stated reason and is there a way out, are those two paragraphs turned into a check the owner can actually run against their own terms.
Business Companion, contract law and unfair terms
https://www.businesscompanion.info/focus/holiday-parks/part-1-contract-law-and-unfair-terms (Chartered Trading Standards Institute, with UK Government)
Business Companion is the Trading Standards funded guidance service for UK businesses. This page sets out what a fair price variation term looks like in practice, in plainer language than the legislation. It states that before the contract is entered into the business must set out in detail how changes will take place, the reasons for them and the method for calculating the increase, that the term must give the consumer plenty of notice, and that the consumer must get "the right to exit the contract without being left worse off if they do not agree with the change". It adds that fairness "is more likely to be achieved if you use an external index to set the new price", giving the Consumer Price Index as the example.
Step 5 takes the notice and exit wording from here, which is why the contract's own notice period is treated as a floor rather than a target. Step 8 takes the external index point, which is what turns a one off price rise into a rule that removes the drama next time.
What was checked and left out
Ofcom's rules on mid-contract price rises would have supplied a hard 30 day notice figure and a penalty free exit, but ofcom.org.uk returned HTTP 403 to every attempt to load the page, so nothing from it is cited. Part 4 of the Digital Markets, Competition and Consumers Act 2024 was read on legislation.gov.uk, sections 258 and 259, which require reminder notices for subscription contracts at six monthly intervals containing the renewal amount and any increase, more prominently than any other information given at the same time. It is named in the Rules only as something to ask an adviser about, because the subscription regime had not commenced when this skill was written and quoting a commencement date from secondary commentary would have been a guess.
Best public prompt we found for this job
The "Rollout Methodology" section of coreyhaines31/marketingskills/skills/pricing/SKILL.md. It is the only public artefact found that treats a price rise as a sequenced release rather than an announcement, and the line worth copying verbatim is this one:
"A price change is a rollout, not a switch you flip."
