Business owners keep asking me: “Should we use ChatGPT, Claude, Grok or Copilot?” It’s the wrong first question. I’ve used all of them on real work, and the better approach is to start with the process, then choose a tool for each step. Here’s one common process: a quote request arriving and a quote going out.
Tools change quickly. This reflects what each product offered in October 2026, so check current features before you buy.
Step 1: Read the request and its attachments → Claude
A customer sends a long spec, a drawing note or a tender. Claude is a good fit for long documents. It can summarise what’s being asked, list what’s unclear, and point back to the sections it used. Ask for the scope, deadlines, anything ambiguous, and questions to send back.
Step 2: Check what’s changed outside your walls → Grok
Material prices, a supplier notice, a competitor’s announcement, news about the customer. Grok searches the live web and public X posts and shows its sources, which makes it handy for “what’s the latest on…” questions. Click the sources before relying on anything. Every AI tool can state wrong things with confidence.
Step 3: Build the numbers → ChatGPT
ChatGPT handles uploaded spreadsheets and data analysis well, and its Projects feature keeps your price rules, past quotes and instructions together so you aren’t starting from scratch each time. You set the prices. The AI helps assemble line items, flags anything odd and shows its working. Spot-check the totals.
Step 4: Write the quote and cover email → ChatGPT or Claude
Both are strong writers, so pick whichever produces drafts that need the fewest edits from you. Give it a past quote you liked, your standard terms and your tone. If your team lives in Outlook and Word, Copilot works inside those apps, and Claude and ChatGPT can also connect to Microsoft 365 once your admin approves it.
Step 5: Follow up → Copilot (if you’re on Microsoft 365), otherwise your usual tool
Many quotes die of silence, not price. Copilot inside Outlook can help you find quotes with no reply and draft a polite nudge. Otherwise, ChatGPT or Claude can draft one from a list you paste in. You press send either way.
| Step | Tool | Why |
|---|---|---|
| Read the request | Claude | Long documents, answers that point back to the source |
| Check the outside world | Grok | Live web and X search with sources |
| Build the numbers | ChatGPT | Spreadsheets, data analysis, Projects |
| Write the quote | ChatGPT or Claude | Strong drafting; pick by your own results |
| Follow up | Copilot or your usual tool | Sits inside Outlook if you’re on Microsoft 365 |
Before and after
An illustrative example, not a client. It is here to show the shape of the change.
Imagine a 25-person fabrication shop where the owner does the quotes.
Before
A spec lands on Thursday afternoon. The owner reads it that evening and misses a clause about delivery windows. Prices come from the last similar job and memory. The cover email starts from a blank page. Follow-up happens when he remembers.
After
Same owner, same judgement. Claude turns the spec into a scope list, unclear points and questions for the customer, with section references he checks against the original. Grok gives a quick, sourced look at recent material and supplier news. A ChatGPT Project holds the shop’s price rules and drafts the line items; he sets the final numbers. The cover email arrives as a draft in his tone. A follow-up reminder is drafted three days later. He still reads, decides and presses send.
What improves is consistency: fewer missed clauses, fewer forgotten follow-ups. I won’t invent a time-saving figure for an example. If you try this, time your own process for two weeks before and after.
Three ground rules
- Use business plans, not personal accounts, for anything involving customer information.
- A person approves anything that leaves the building.
- Test two tools on the same real job before you commit to one.
Not sure which process to try first?
The free Process Scan takes a couple of minutes, needs no email, and suggests a first process to look at and tools to test. If you’d like a written plan afterwards, the paid Process Scan is $350 CAD.
