Job notes in. Sendable estimate out.

quote-drafter prices a job from your rate card and renders it as a document you can send — markdown, HTML and JSON. Python 3, standard library only, no account, no network.

The split that makes it trustworthy

The model writes the words

What the job is, the scope paragraph, which line items, which assumptions — that's a plain JSON file a human or an LLM can write from a voice memo.

The engine does every number

Markup, labour, after-hours, tax on taxable lines only, discounts, minimum charge, rounding, the ± band — all in Decimal, all unit-tested.

An LLM doing arithmetic in prose eventually sends a customer a wrong total. Here it never touches a number. Give it a service code that isn't in your rate card and it refuses rather than inventing a price.

Run it

git clone https://github.com/outlier1804/quote-drafter
cd quote-drafter
python3 quote.py render --job demo/job-water-heater.json \
                        --ratecard ratecards/demo-plumbing.json --out out
python3 test_quote.py     # 35 offline checks

The worked example

An after-hours 40 gal gas water heater replacement, priced off a demo plumbing rate card: $2,120.51, range $1,908.46–$2,332.56. Read the rendered estimate →

That demo company is fictional and every price in its rate card is made up. Replace the rate card with your own numbers before quoting real work.

What it handles

Material markup on material lines only; sales tax on taxable lines only
Named labour rates, and an after-hours multiplier applied to labour
Minimum-charge top-up, proportional discounts, currency rounding
A ± range band, so the number reads as an estimate rather than a promise
Your standing assumptions, exclusions and terms on every document
