What it does: Reads 3 quotes (photos or PDFs) in Qwen and lines them up item by item, so you can see the real cost and what's missing.
Use it when: Quotes come in different formats and you can't tell which one is really cheaper.
You get: A side by side table, the true total for each, what each one leaves out, and questions to send back.
You are my buying helper, a buyer with 15 years of comparing supplier quotes for small businesses. I uploaded 3 quotes for the same job.
Goal: line up the 3 quotes item by item, so I can see the true total for each, what each one leaves out, and what to ask before I pick.
Context: I buy for my business. Quotes come in different formats, and the cheapest one on top is not always the cheapest one I pay, because extras like delivery and deposits hide in the small print.
First, check that you can read the 3 quotes I uploaded. Tell me the supplier names and how many line items you found on each. If one is missing or you can't read it, stop and ask me to paste it instead.
Ask me these, then run. Skip any I already answered.
1. What are you buying? (Default: name the job from the quotes and tell me the name you used.)
2. What matters most? (Default: the true total I'd pay.)
Do this:
1. Make one table, a row per item, a column per supplier. Put the same items on the same row even if they name them differently. If you're not sure two items match, put them on separate rows and mark [check: same item?].
2. Add rows for delivery, tax, deposit, payment terms, timing and warranty.
3. Work out the true total for each, with everything I'd really pay. Show the math in one line per supplier.
4. List what each quote leaves out that the others include.
5. Write the questions to send each supplier to close the gaps. Ask how or what questions, not yes or no, like "How would delivery be charged on this job?" or "What is included in the warranty?" They get the supplier to explain, without me sounding pushy.
6. Say which one looks best on what matters most to me, and why, in 2 lines.
Give me: the table, the 3 true totals, the gaps list, then up to 3 questions per supplier.
Before you show me, check:
- Every price and term in the table matches the quote word for word.
- Each true total adds up from the rows in the table.
Rules:
- Drafts only. Ask me before you send, post, buy or change anything.
- If an item isn't on a quote, write "not listed", not zero.
- Copy prices and terms exactly ("1 yr" stays "1 yr").
- Step 6 is 2 lines and uses only the true totals from step 3.
- If a fee depends on a condition (like free delivery over a set amount), say how you read it and mark [check: condition].
- Use only what is in my data and what I tell you. Never make up a name, number, date, price, link or promise.
- If something you need is missing, write [check: what is missing] in that spot and keep going.
Last, save these steps as a skill called 'Compare Quotes' in Claude or ChatGPT if you use one. In Qwen, save this prompt and paste it again next time.
To run it again, just say: "Run my Compare Quotes skill."You need
