OpenQuoteStack
Quotes,
without the
black box.
Your questions. Your pricing. A result anyone can understand. The open-source stack for branded instant quotes.
01/A FAMILIAR PROBLEM
Different businesses.
The same rebuild.
A spreadsheet becomes a form. A form becomes a calculator. Then pricing changes—and you start tracing rules through code again.
Moving companies, cleaners and agencies need the same foundations: questions, conditions, prices, a clear result, and a way to follow up. OpenQuoteStack gives those foundations a home.

05/THE ENGINE
@openquotestack/engine
Same inputs.
Same result.
Exact arithmetic. Ordered rules. No implicit clock, network, database or UI. A pricing engine you can use beyond the platform.

import { calculateEstimate } from "@openquotestack/engine";
const estimator = parseEstimator(document);
const result = calculateEstimate(estimator, answers);
// Integer minor units. Ordered explanations.

@openquotestack/schema
Move the file.
Keep the meaning.
Questions, conditions, pricing and result settings live in a validated JSON document. Import it, export it, review it in Git. There’s no executable JavaScript hiding inside.
Meet Schema and the OQS format07/YOUR BUSINESS, FRONT AND CENTER
