Nero Quote Builder

Turns a UK tradesperson's site visit into a priced, VAT-correct quote with a branded PDF and a phone page the customer accepts in one tap. For electricians, plumbers and heating engineers, builders, roofers and decorators.

Endpoint: https://quote-builder.nerolabs.workers.dev/mcp (MCP, Streamable HTTP) Sign-in: No account sign-in. The first call (setup_trade) gives the business a private key starting qbk_. Your AI keeps it and passes it with each call; in apps that allow headers you can set it once as "Authorization: Bearer qbk_...". Lose the key and you set up again.

Tools

Tool	What it does
setup_trade	Set up or update the business quoting profile. Create a business, or update its saved settings (call with trade_key to update).
get_trade	Show the business profile, price book, stats and free allowance. The trade's saved settings, price book (most used first), quote stats (win rate, value won in the last 12 months) and, for a business that is not VAT registered, a warning when accepted work is nearing the £90,000 VAT registration threshold.
save_price_items	Save materials to the price book. Add or update materials in the trade's price book, so later quotes can use { code, qty } and the cost, unit and markup fill in.
draft_quote	Draft a priced, VAT-correct quote. Price a job after a site visit.
revise_quote	Change or withdraw a quote. Change a quote. Send only the fields that change (a list you send, such as materials, replaces that whole list).
finalise_quote	Finalise a quote and get the customer link. Lock a draft so the customer can answer it.
quote_activity	See what customers did with quotes. What customers have done since the trade last checked: quotes opened, accepted (with the name they signed, extras ticked and final total), questions asked, declined.
get_quote	Show one quote in full. One quote in full: lines, totals, VAT working with HMRC sources, margins (trade only), the customer's answer, history (drafted, sent, opened, accepted) and links.
list_quotes	List quotes. Recent quotes, newest first, with status (draft, sent, viewed, queried, accepted, declined, expired, withdrawn), total and whether there is news.
reply_to_customer	Answer a customer question on the quote page. Answer a customer's question.
export_to_nero_work	Export a quote in Nero Work format. The quote in the exact argument shape of the Nero Work exchange's submit_quote tool (labour_minor, materials_minor, vat_minor in pence, validity_hours, exclusions, notes), checked with Nero Work's own rules.

Every tool carries a plain title and the read-only, destructive and open-world hints, so your AI app can ask before anything that changes data.

Good to know

• Free: 5 finalised quotes a month for every business, counted per UK calendar month. Drafts, revisions, replies and exports never count. There is no paid plan and no card.
• The tool never sends anything to your customers. You send the link yourself by text, WhatsApp or email.
• VAT is worked out from your VAT registration and each line's VAT type, with the HMRC rule named. You stay responsible for the prices and VAT treatment you choose.
• Every quote can be handed to Nero Work, the job exchange for trades, in its exact quote format.
