Yes, with the paid Microsoft 365 Copilot licence. Open Copilot in Word, describe the proposal, and type / to pull in your own documents, emails or meetings as sources. Without that licence, Copilot in Word can still work from the open document and anything you paste in, but it won't search across your files.
Check which version you have before planning around it. Microsoft shows a label in Word's Copilot experience: Microsoft 365 Copilot (Premium) means the paid licence, (Basic) means standard access without it, and Copilot Chat (Basic) means no Copilot chat inside Word at all. The licence, Copilot Business, lists at $21 per user a month on annual billing, with a promotional $18 until 31 December 2026.
Which Copilot you have decides what it can read
Microsoft's naming changes often, and its product is now called Microsoft Copilot in places where it used to say Microsoft 365 Copilot. The labels are the reliable guide. Microsoft Learn's Copilot Chat overview, updated in September 2026, sets out what each can draw on:
| Label you see | What it means | What Copilot can use for a proposal |
|---|---|---|
| Microsoft 365 Copilot (Premium) or (Pro) | You have the paid add-on licence | The open document, files you name with /, and reasoning across your emails, meetings, chats, documents and sites that you already have permission to see |
| Microsoft 365 Copilot (Basic) | No add-on licence, but standard access to Copilot in Word | The open document, text you paste, and content you provide directly; no broad search of your organisation's files |
| Copilot Chat (Basic) | No add-on licence and no Copilot chat in Word | Nothing inside Word; use Copilot Chat on the web with uploaded files instead |
In money terms: Copilot Business is $21 per user a month on annual billing, or $25.20 billed monthly, and applies to organisations of up to 300 users. Bought as a bundle, Business Standard plus Copilot is $23.50 a user a month on annual billing, which is less than the $14 plan and the $21 add-on bought separately. A three-person team on Business Standard adding Copilot through the bundle pays $70.50 a month, against $105 for the plan and the add-on bought separately. What you get free and what the licence adds is set out in Copilot Chat vs Microsoft 365 Copilot.
Getting the source files ready before you ask
Copilot only reads files you already have permission to open, and it finds them best when they're in OneDrive or SharePoint with names that say what they are. Twenty minutes of preparation before your first AI-drafted proposal pays back on every one after it.
- Make a proposal kit folder. Current price list, your standard terms, insurance and accreditation certificates, two or three strong past proposals, and a one-page "about us". Keep it in SharePoint or OneDrive so everyone drafting uses the same versions.
- Strip client details from the past proposals in the kit. Save anonymised copies: client name replaced with [CLIENT], their prices removed, their site details gone. The worked example below shows why.
- Date every file name. "Price list 2026-09", not "Price list final v2". Copilot picks sources by name and content, and an old price list matches as well as a new one.
- Check who can see the folder. Copilot respects permissions, so a proposal kit shared with the whole company means anyone's Copilot can draw on it. That's usually fine for a kit, and not fine for folders holding contracts or staff records; cleaning up SharePoint permissions before Copilot explains the check.
A dry cleaner's care-home proposal, drafted from five sources
Take an illustrative dry cleaner with a commercial laundry side, bidding to clean staff uniforms and residents' personal clothing for a group of three care homes. The owner has the paid Copilot licence and five relevant sources: the price list, an anonymised past proposal to a hotel, the notes from a Teams meeting with the care group's operations manager, an email thread with their questions, and the firm's insurance certificate. She opens a blank document and writes:
Draft a proposal to [care group] for weekly uniform and residents'
clothing cleaning across their three homes.
Use prices only from /Price list 2026-09.
Follow the structure of /Hotel proposal 2025 (anonymised).
Scope and service levels come from /Site meeting with care group 9 Sept
and /Email thread - care group questions.
Cover: summary, what we'll do, collection and return times, pricing
table, handling of residents' labelled items, insurance, next steps.
Where a fact isn't in these sources, write [CHECK] instead.The illustrative first draft took about a minute and ran to four pages. The pricing table read: 180 uniforms a week at $2.40 each, $432 a week; 60 residents' bags a week at $9.50, $570; weekly total $1,002, about $52,100 a year. The summary picked up the care group's own words from the email, "fewer lost items and a predictable weekly cost", which is exactly what a buyer wants to see reflected back.
Two problems surfaced on the owner's read-through. The turnaround section promised "48-hour return", which came from the hotel proposal; the meeting notes said the homes need 24 hours for uniforms, which changes the collection rota and possibly the price. And in the insurance section, one sentence still named the hotel, "as we do for [hotel name] across 90 rooms", because the "anonymised" copy had missed a mention in a footnote. Sending that would have shared one client's name with another. Both were fixed in ten minutes, and the kit's hotel proposal got a proper second pass for names.
| Stage | Last proposal, by hand | This one, with Copilot |
|---|---|---|
| Gathering prices, notes and past wording | 45 min | 5 min, writing the prompt |
| First draft | 120 min | 2 min |
| Checking every figure, date and promise against sources | 15 min | 35 min |
| Fixing [CHECK] gaps, tone and the two errors | n/a | 40 min |
| Final read and formatting | 30 min | 20 min |
| Total | 3 h 30 min | 1 h 42 min |
About half the time, then, with the checking stage more than doubling. That's the right shape. If a team's Copilot-drafted proposals take less checking time than hand-written ones did, the checking has probably been skipped.
Which source feeds which section
After a few proposals, the dry cleaner settled on a fixed map of sections to sources, which made prompts shorter and errors rarer:
| Proposal section | Source to reference | Watch out for |
|---|---|---|
| Summary | The client's own email or meeting notes | Promises the client never asked for |
| Scope of work | Meeting notes, then the email that confirmed them | Ideas discussed but not requested |
| Pricing | Current, dated price list only | Discounts or minimums kept in notes, not cells |
| Service levels | The client's stated needs, not a past proposal | Another client's turnaround times |
| About us, insurance, accreditations | Certificates and the one-page "about us" | Claims written from general knowledge |
| Terms | Your standard terms file | Paraphrasing that changes the meaning |
The last column is the checklist for each section's read-through. Each error in the examples here traces back to one of those six cells.
Pulling in a meeting and an email, not just documents
The / menu reaches beyond files. Microsoft's help pages describe typing / in the Copilot pane and starting to type the name of a document, email or meeting. For proposals that's the most useful part, because the client's actual requirements usually live in a meeting and an email, not a document.
An illustrative garden centre with a grounds-maintenance service used it for a planting and upkeep proposal for a business park. The prompt referenced the Teams site-visit meeting and the facilities manager's follow-up email. The draft's scope section included "installation of a rain garden at the north car park", which had been mentioned in the meeting, but as an idea the facilities manager wanted to think about, not a request. Copilot had treated everything discussed as agreed. The fix was a line in the prompt, "include only items the client asked us to quote for; list anything else discussed under 'Options you mentioned'", which turned the rain garden into a priced option rather than a surprise in the total. How Teams meeting notes are produced, and what they capture, is covered in Copilot in Teams meetings: recaps, actions and privacy.
Checking the numbers Copilot carried across
Figures move from spreadsheet to proposal through Copilot's reading of the source, and that step can drop rules that live outside the numbers themselves. An illustrative optician's practice drafted a proposal for a local employer's staff eyecare scheme: eye tests for 120 staff at $45 each. Copilot's table showed $5,400, arithmetically right, but the practice's price sheet gives 10% off for schemes over 100 staff. The discount sat in a note beside the table, not in a cell, so Copilot never applied it. The proposal would have quoted $540 more than the practice's own policy.
That kind of error favours the business, which makes it easy to miss and bad for trust when a client spots it later. Three habits catch most of them:
- Put pricing rules in the prompt, not only in the source: "apply the 10% scheme discount for over 100 staff".
- Recalculate every total in the proposal's pricing table with a calculator or in Excel. It takes two minutes.
- Ask Copilot to list its figures: "list every number in this proposal with the source file it came from". Anything without a source is a guess.
The fuller routine is in AI proposal mistakes that cost you the job, and for firms that want a second person to sign off, setting up an approval step for AI-written quotes shows a light-touch version.
Rewriting one section without losing what matters
Copilot is often more useful on a single section than on a whole draft. An illustrative picture framer bidding to frame 40 prints for a new office had an "about us" paragraph that ran to 140 words of history. Selecting it and asking Copilot to "rewrite this in under 60 words for an office manager choosing a framer" produced:
We're an independent framing workshop with 15 years' experience framing for homes, galleries and businesses. Every frame is made to order in our own workshop, and we install on site, so your walls are finished in one visit.
Tighter and more relevant, but it had dropped the one line that mattered for this buyer: the workshop's conservation framing accreditation, which the office wanted because several prints were limited editions. The rewrite prompt hadn't said what to keep, so Copilot kept what sounded most general. The fix was to name the essentials: "keep the conservation accreditation and on-site installation; cut the history". Whenever you ask for a shorter version, list what must survive the cut.
Pressure-testing the draft in Chat only
The Copilot pane in Word works in Edit mode by default, changing the document as you ask. Switching to Chat only gets answers without edits, which is ideal for reviewing a draft. Microsoft lists "pressure-test ideas" among the things Copilot in Word is for. The dry cleaner asked:
Read this proposal as the care group's operations manager.
What questions would you still have before signing?
Base them on the meeting notes and email thread.1. What happens if a resident's labelled item is lost or damaged? 2. Can collection times be changed at short notice for inspections? 3. Is the weekly price fixed for the contract term, or reviewed? 4. Who do we call if a delivery is late?
Questions 1 and 3 were real gaps: the draft said nothing about lost items or price reviews, and the email thread showed the care group had asked about lost items twice. Adding a short section on each, with a clear compensation limit and a 12-month price review, strengthened the proposal more than any wording change. This review step takes five minutes and is the one most teams skip.
Drafting without the paid licence
If your label says Microsoft 365 Copilot (Basic), you can still get a good first draft; you just supply the sources yourself. An illustrative music teacher preparing a proposal to a primary school for a weekly after-school guitar club had no Copilot licence. She pasted her notes from the head teacher's call and her price per session into the open document, then asked Copilot to "turn the notes above into a one-page proposal: club outline, term dates, group size, price per pupil per term, equipment, safeguarding".
The draft was usable, with one fix: it described "a qualified music teacher with enhanced background checks", a detail she had never provided. She did hold the relevant check, but Copilot had supplied the wording from general knowledge, and in a school proposal every such claim needs to match the actual certificate. She replaced it with the certificate's exact name and date. For occasional proposals like this, Basic is enough. The licence starts to pay when you're drafting often from emails, meetings and many files, which is when typing / saves real time.
Businesses on Google Workspace have a close equivalent in Gemini, compared in using Gemini in Google Docs to draft and edit.
A pre-send checklist for AI-drafted proposals
Filled in as the dry cleaner used it on the care-home proposal:
| Check | Care-home proposal |
|---|---|
| Every price traced to the current price list | Yes, all four lines |
| Totals recalculated by hand | $1,002 a week confirmed |
| Service levels match the client's stated needs | Corrected from 48 to 24 hours |
| No other client's name, price or detail anywhere | Hotel mention removed from insurance section |
| Every claim about us matches a certificate or record | Insurance limits checked against the certificate |
| All [CHECK] markers resolved | Three resolved |
| Client's open questions answered | Lost items and price review sections added |
| Read in full by the person signing it | Owner, 20 minutes |
