THE SHORT ANSWER
Ask for an important sales promise to be clearly reflected in the agreed documents before committing payment. Preserve the original statement, identify the exact gap and request a specific written commitment from an authorised person. A promise outside the main contract is not automatically meaningless, but a vague reassurance leaves room for disagreement about scope, price and timing.
The demo sounded right: migration included, support available when you need it, and everything ready for your launch. The contract says “standard onboarding” and links to terms you have not read.
Before buying, work out whether those phrases describe the same service. You need an answer the delivery team can act on, not just a repeat of “don't worry, we'll take care of you.”
Save the promise and its context
Keep the dated quote, proposal, emails, relevant website wording and your notes from the sales conversation. Record who made the statement and any qualifications given at the same time. “We can usually migrate that” is different from an agreed migration commitment.
Keep an existing recording only where you are entitled to retain and use it; a written follow-up is also useful. You do not need to make a secret recording to ask a clear question.
Read the full set of proposed documents. The missing detail may be in a statement of work, order form or incorporated service description. Check that the referenced version is available and that you understand which document prevails if they conflict.
Build a promise-to-contract worksheet
This fictional software purchase shows the difference between an attractive phrase and a decision-ready answer:
| Sales statement | Written wording | Clarification to request |
|---|---|---|
| “We will move your existing data” | “Standard onboarding included” | Which records, attachments and history are included, with what limits? |
| “Ready for your October launch” | No implementation date | What delivery date, customer inputs and acceptance steps are agreed? |
| “Support whenever you need it” | “Business-hours support” | Which timezone, channels and response targets apply? |
| “You can export everything” | “Export available” | Which formats, assets, fees and post-cancellation access are included? |
Fill your own worksheet with exact passages. Leave a gap marked “not found” rather than assuming that silence means either inclusion or exclusion.
Pick the promises that affect your buying decision. A missing migration commitment can change the total project cost; an unclear response time can change whether the service works for your business. Resolve those before spending time polishing minor wording.
Request an outcome, boundary and date
“Please confirm migration is included” can still produce an ambiguous yes. Describe what needs moving, what counts as completion, who supplies inputs, the price and the timing.
For example, a fictional buyer might ask to include migration of 4,000 contact records and their attached notes from an agreed export, with a sample checked before the remaining import. That is more useful than a promise to “migrate the CRM,” which might omit attachments, history or cleanup.
Ask who can approve the commitment and how it should be recorded. The agreement may require changes in a signed order form or an amendment. A sales email can be useful evidence without necessarily completing that process.
Send a precise pre-payment email
Before we proceed, I'd like to resolve one point from our sales conversation. On [date], [person] said [specific promise]. The order form currently says [exact wording], which does not explain [gap].
This affects our decision because [practical reason]. Could you include [specific scope, timing and price] in the agreed order form or statement of work, and confirm any dependencies or exclusions? Please send the complete revised documents so we can check the final version before proceeding.
If you have already signed or a payment obligation has arisen, do not assume this email suspends it. Ask how the parties will resolve the discrepancy and check the existing payment terms before withholding a due payment.
For other tones and situations, use the contract-clarification email guide. When the revision arrives, check that it actually fixes the request, including any new exception elsewhere.
Do verbal promises count?
Do not assume that only the main document can matter. The answer depends on the governing law, type of purchase, wording, evidence and the person's authority. Look for terms about the entire agreement, reliance on earlier statements, incorporated documents and amendments; do not treat their presence as a universal answer either.
One specific example is a UK consumer service contract. Section 50 of the Consumer Rights Act 2015 can make information said or written about the trader or service part of the contract when the consumer takes it into account in the relevant decision. Qualifications made on the same occasion and expressly agreed changes matter. This is a consumer example, not a general rule for business software purchases. Source checked 15 September 2026.
The practical pre-purchase move remains the same: make a material promise specific and resolve contradictions while the supplier can still revise the offer. Preserve evidence even if the seller says its standard wording cannot change.
Carry the commitment into delivery
Once the wording is agreed, give the onboarding or delivery contact the same scope and acceptance steps. Ask them to confirm the plan and dependencies. This catches the common operational gap between what sales discussed and what the people doing the work received.
For business owners seeing repeated expectation gaps, our other project Call Nerd has a guide to finding repeated customer questions. It is a useful next read about patterns in customer conversations, rather than evidence that a particular promise is legally binding.
If the disagreement is really about what each supplier includes for the price, use the quote-comparison worksheet before choosing between them.
