Drafts from the enquiry
Paste an email, a WhatsApp, an RFP, or notes from a call. A complete proposal comes back — opening, scope, pricing, terms — in a voice learned from proposals you've already sent.
Proposal software, properly defined
AI proposal software,
with a human on the send button.
Most proposal software gives you templates and a text box. Chalmsy reads the enquiry — or the RFP — and drafts the whole proposal in your own voice, priced from your own rates, materials and multipliers. You read it, adjust it, and press send. For any small business that wins its work by proposal: florists, planners, venues, designers, consultancies, contractors and trades.

More than a pretty document
What proposal software should actually do.
A proposal isn't the end of anything — it's the first link in a chain that ends with money in your account and clean books. Most proposal tools stop at the signature. Chalmsy runs the whole chain.
Carries the negotiation
Clients comment on the exact line they mean through private, per-person links. They can suggest additions; you accept them as costed sections or leave them.
Takes the signature
E-signature with a code sent to the signer's own inbox. The agreed version locks, and change orders are versioned — signing v2 is never mistaken for v3.
Raises the invoices
An accepted proposal becomes an invoice in one click — deposit, stage and balance schedules included — sent from your own email address.
Keeps the books
Receipts photograph into a categorised ledger and a live profit & loss, with QuickBooks Online sync. The proposal you sent in March explains the margin you see in June.
Not a toy generator
An AI proposal generator that earns the name.
The free AI proposal generators produce the same five paragraphs for everyone, and they'll cheerfully invent a price. Chalmsy is built on three rules that make AI safe to put in front of your clients.
It writes in your voice
Not a prompt box — the AI learns from proposals you've already sent: your phrasing, your structure, the way you explain a price and sign off. Ten years of your writing, put to work on Monday's enquiry.
It cannot touch your prices
Every figure comes from your own price guide, recipes and supplier lists — and a number you type in by hand is locked. The AI can tidy the sentence around a price; it cannot alter the price.
A human approves every send
Nothing reaches a client until you've read it and pressed send. The draft is the butler's job; your name on it is yours. Clients receive a proposal from you — because it is from you.
Quoting software, included
Itemised quotes from your own arithmetic.
When the job is itemised — time, materials, and the multipliers your trade actually works to — the quote builds itself from numbers you control, not a template's guess.
- Recipes & spec builds — a repeatable job saved once, dropped into any proposal and adjusted: an arrangement, a fit-out, a survey package, a retainer scope.
- Supplier price lists — the prices you actually buy at, on file and pulled straight into the quote.
- Your own markup rules — set them once and every quote costs itself from your real margins.
- Tiered options — good, better and best in one document, each fully costed, for the client to choose.
- Hard-input pricing — a negotiated figure is entered once and stays exactly as you typed it. Nothing recalculates it, ever.

Plain answers
The questions people ask about proposal software.
What is proposal software?
Software that produces, sends and tracks the document a client says yes to — the scope, the price, the terms, the signature. Good proposal software also carries what follows: the negotiation, the change orders, the invoices, and ideally the books. Chalmsy covers that whole chain, with AI drafting the first version in your own voice.
What's the difference between a quote and a proposal?
A quote is the price; a proposal is the argument — the scope, the approach and the price together, presented well enough to win the work. Chalmsy produces both from the same source: your rates, materials and multipliers become an itemised quote, and the AI wraps it in a proposal written the way you write.
Can ChatGPT write a business proposal?
It can write a proposal. It can't write yours — it doesn't know your rates, your past work or your voice, and it will invent a price without blinking. Chalmsy's AI drafts from proposals you've already sent and prices from your own numbers, and a figure you enter by hand is one the AI cannot touch.
Will clients be able to tell the proposal was AI-drafted?
Only if you tell them. The words are learned from your own sent proposals, nothing is watermarked, and you read and edit every draft before it goes. Your client receives a proposal from your business, in your voice, from your email address — which is what they received before.
Does it handle e-signatures and invoicing too?
Yes — that's the point of the chain. E-signature with email-code verification and versioned change orders is included on every plan, and an accepted proposal becomes an invoice in one click, with deposit, stage and balance schedules, from the Studio plan up. Bookkeeping and QuickBooks sync join at Practice.
What does proposal software cost?
The market runs from free toy generators to $100+ per user per month for enterprise suites. Chalmsy is $15 a month for one person, $59 for a three-seat studio with invoicing, and $199 for a ten-seat practice with bookkeeping — seats included, never billed per user. The pricing page has every line.
Can it draft a proposal from an RFP?
Yes — paste the RFP in and the draft comes back scoped and costed for you to shape. What Chalmsy is not: enterprise RFP-response software with answer libraries and compliance matrices. If your work is security questionnaires for procurement teams, that's a different tool. If your work is turning a client's brief into a winning, priced proposal — that's exactly this.
Already using something?
Compare honestly. Switch gently.
See how Chalmsy stacks up against the usual combination of a front-office suite, a trade calculator and an accounting tool on the comparison page — gaps included. And if you decide to move, the migration is free and we do it for you, while your old system keeps running.
