From "I'll get you a quote" to job booked today
The first professional quote usually wins the job. Here is how plumbing service work runs when the quote, the job, and the invoice are one record.
Quote it on-site, win it on-site
Build the quote on your phone while you are still at the house: line items, photos of the problem, your terms. Email it for approval on the spot. The plumber who quotes first usually books the job.
Approved quote becomes the scheduled job
One click converts the approved quote into a work order on the calendar. The tech sees the address, the quoted line items, and the photos. Nothing is retyped, so the job gets done exactly as quoted.
Job closes, invoice lands in QuickBooks
The quoted line items become the invoice when the job closes. QuickBooks Online invoices auto-generate; QuickBooks Desktop syncs via Web Connector at preset intervals. Quoted price, billed price, and your books always agree.

Why field service businesses stay with Field Promax
Answers before you ask
The questions plumbing business owners ask us most when choosing quoting software.
What makes Field Promax good plumbing quoting software?
Because the quote is connected to everything after it. You build the quote on-site from your phone, the approved quote becomes the scheduled work order, and the quoted line items become the invoice in QuickBooks. One record from first visit to paid, with no retyping at any step.
Is this for mechanical estimating or blueprint takeoff?
No. Field Promax is not a takeoff tool and does not do material quantity estimation from blueprints. It is built for service and repair plumbing businesses: quoting jobs, scheduling techs, tracking work orders, and invoicing. If you bid new-construction mechanical work from plans, you need a different category of tool.
Does Field Promax sync with QuickBooks?
Yes. With QuickBooks Online, invoices auto-generate the moment a work order is closed. With QuickBooks Desktop, data syncs through the Web Connector at preset intervals. Either way, you never type the same job twice.
How long does setup take?
Most customers are set up within an hour. Our team does it for you: QuickBooks connects, and your customers and jobs are imported, so your team can start dispatching the same day.
Can plumbers build and send quotes from their phones?
Yes. The mobile app runs on iOS and Android. Build the quote on-site with line items and photos, email it for customer approval, and convert it to a scheduled work order the moment they say yes.
Is there a free trial?
Yes. After your free 30-minute demo, you get a 14-day trial so your team can run real work orders in the system before you commit. No credit card required to start.
