DukeOS for plumbers and electricians · AI operating systemCRM, ERP and AI agents in one system. From $49 a month per business. About DukeOS
DukeOS is the AI operating system for plumbers and electricians: enquiries, visits, job sheets, quotes, service plans, invoices and WhatsApp in one app, with Duke, an AI assistant that prepares the work for your approval. Duke answers WhatsApp while you work, books the visit with a free technician and saves the address and what's wrong. Each technician sees only their own visits.
01Duke at your plumbing and electrical business
Leaks, tripping breakers, a boiler that won't fire: he answers on WhatsApp with your visit price, books a free slot with the right technician and saves the address and access notes on the customer's site. Quotes, invoices and follow-ups wait for your yes.
Who decides
A day with Duke
A Tuesday at a plumbing and electrical firm in ColumbusDuke does this for you
With booking and capture on, Duke gives your visit price, never a made-up one, books the time the customer picks and writes the address and access notes on their site.
Every job sheet sits on a board from Booked to Done. Ask Duke what's waiting for parts and he lists each one with the site and the technician.
Job sheets · Waiting for parts
The Follow up quotes agent looks each morning for quotes sent three or more days ago with no answer and drafts a short email for each customer. They go once you approve.
Sell a yearly service plan for a boiler service or an electrical safety check. Visits don't repeat in the diary on their own, so Duke lists plan holders with nothing booked yet.
Service plans · No visit booked
02The apps plumbers and electricians use
Leads from WhatsApp and your service request form, visits by technician, a job sheet for each one, quotes for bigger work, yearly service plans and invoices.
03In the app
Screens from our live demos, and what each part does for the business.
01Visits
Service visits, call-outs and site surveys as visit types, each with its length and a travel buffer. Free times come from each technician's hours. The office books for everyone; each technician sees only their own visits, with the customer's address and phone.
02Job sheets
A ready-made Job sheet for every visit, linked to the site: technician, work done, parts used, hours on site and whether the customer signed off. Sites keep the address, access notes and what's installed, like the boiler and when it went in.
Job sheet · 48 Oak St
03Quotes and invoices
Labour and parts as lines, with tax. When the customer accepts, the order is made from the same lines, and invoices show what's paid, due and overdue.
Ready-made pages
A plumbing and electrical business starts with Sites and Job sheets, linked to the customer. Add your own, like Safety certificates or Van stock checks, by asking Duke.
04No code
DukeOS is an AI CRM that builds the whole business, not just code. Every plumbing & electrical gets working apps by asking, with fields, a board, a place in the menu and permissions.

07Questions
Yes. The Technician role sees only their own visits and schedule, with the customer's address and phone, and the job sheets. It doesn't see leads. Office and dispatch books visits for every technician, quotes and invoices.
Yes. The Service request form asks for name, phone, address, what they need, when suits them and an optional photo. You can share it as a link, a QR code poster, a section on your website or on another site. Every answer finds or creates the contact and can start a lead.
No. Visits don't repeat in the diary on their own. A service plan holds how many visits are included and when it ends; Duke lists plan holders with nothing booked, and a reminder goes out before a plan ends.
