Where commercial service contracts lose money
Winning the contract is the hard part. Keeping it means every visit done on time, documented, and billed, across every site.
Documentation the client can't find
Inspection sheets on paper, photos in a tech's camera roll, signatures nobody scanned. When the facility manager asks for proof, the office spends a day digging.
Work done, invoice weeks later
Contract visits, extra calls, and project work all get billed from notes after the fact. Things get missed, and disputes slow every payment.
One service request at a client site, from portal to paid
A same-week call at a multi-site client when the request, the dispatch, the equipment record, and the invoice all live in one system.

Requested in the client portal
The facility manager logs a request for one of their sites in your branded portal. It lands in your scheduling queue with the site, contact, and notes attached.

Dispatched to a certified tech
FieldNexus suggests the closest tech with the right skills and certifications. One tap puts the job on their phone and lets the site contact know.

Equipment history on screen
The tech scans the unit's QR code to pull up its service history, then works through the required checklist with photos and readings.

Bigger fix quoted and approved
The tech sends a quote with repair options. The facility manager signs digitally, and the accepted quote becomes a work order or a project.

Signed off, invoiced, in the portal
The site contact signs on the tech's phone. The work order becomes an invoice in one tap, appears in the client's portal, and syncs to QuickBooks or Xero.
How it works
Commercial service management software, built around the client site
Replace the site spreadsheet, the paper inspection forms, and the after-the-fact billing with one system for the office, the crews, and your clients.
Every site, every contract visit, every crew on one board
Set up each client once with all of their locations. Preventive maintenance contracts book every visit for every site, and the dispatch board shows every crew, job, and status live. Urgent calls go to the closest tech with the right certifications.
- Unlimited locations per client, each with its own contacts and notes
- Contract visits scheduled automatically when an agreement activates
- Skills- and certification-based dispatch across crews
- Live status and a live map of every tech
Audit-ready records on every visit
Build the inspection and maintenance forms your clients require, assign them to job types, and make the important fields required. Techs complete them on site with photos and signatures, and every record is stored against the site and the equipment.
- Custom forms per job type, with required fields
- Photos, readings, and signatures captured in the form
- Equipment history per site, one QR scan away
- Full audit trail of every change on the work order
Projects and proposals next to the service work
Send proposals with options, get them signed digitally, and turn the accepted one into a project with phases, crews, and dates. Track materials against the estimate, keep the client updated as phases complete, and see profit when it closes.
- Several options on one proposal, signed digitally
- Multi-phase projects with crews and dependencies
- Materials and costs tracked against the estimate
- Deposits and partial payments for larger jobs
And the rest of the business, in the same system

Mechanical room or parking garage?
No signal, no problem.
Basements, rooftops, and concrete cores are where commercial work happens and where the bars run out. The FieldNexus app keeps working offline, so techs finish the inspection, capture the sign-off, and move to the next site. The office catches up the moment they're back in range.
Keep working with no bars
Update job status, complete required forms, log parts, take photos, and capture signatures without waiting for a signal.
Nothing is lost
Every change is saved on the phone and queued, so a dead zone never means a missing inspection record.
Syncs on its own
When the phone reconnects, queued work syncs automatically and the office sees it. No one re-types anything.
Keep every site on schedule and every visit on record
Multi-site accounts, maintenance contracts, and paperwork your clients can see. See it in a 30-minute demo.

What is commercial field service software?
Commercial field service software runs the business side of a contractor that serves commercial clients: multi-site accounts, preventive maintenance contracts, dispatch, work orders and inspection forms, equipment records, projects, invoicing, and a client portal. FieldNexus covers all of these, with a mobile app for technicians in the field.
Can FieldNexus manage multiple locations for one commercial client?
Yes. Each client can have unlimited locations, each with its own contacts, notes, equipment, and service history. Jobs, agreements, and invoices are tied to the right site, and the client sees all of their locations in one portal.
Can FieldNexus run preventive maintenance contracts?
Yes. Service agreements define the visits, pricing, and billing frequency. Visits are scheduled automatically when the agreement activates, billing runs on repeat, and clients and your office get reminders before renewal. You can see revenue and cost for every active agreement.
How does FieldNexus handle compliance documentation?
Build custom forms for any inspection or maintenance requirement, assign them to job types, and mark fields as required so a job can't be closed without them. Techs add photos and signatures in the form, and every completed form is stored and searchable in the client's record, with a full audit trail on the work order.
Can I dispatch based on technician certifications?
Yes. FieldNexus matches jobs to technicians by required skills, certifications, location, and workload, and suggests the best available tech. You can confirm with one click or reassign on the dispatch board.
How does the client portal work for commercial customers?
Clients get a portal with your branding where they see upcoming and past appointments, service history for their equipment, signed agreements and documents, and open invoices. They can pay online and submit new service requests, which land in your scheduling queue.
Can FieldNexus manage larger commercial projects?
Yes. Project tracking splits a job into phases with their own crews and dates, assigns tasks with dependencies, tracks materials and costs against the estimate, sends clients milestone updates, and shows profitability when the project closes.
Does FieldNexus work with QuickBooks?
Yes. Invoices, payments, and customers sync both ways with QuickBooks and Xero, with your service items mapped to your chart of accounts.
How much does commercial field service software cost?
FieldNexus pricing scales with your team size and the features you need. Every plan starts with a 14-day free trial with no credit card required, and a demo is the fastest way to get an exact quote and scope guided implementation for larger teams.
How long does it take to get set up?
Most teams schedule their first jobs within a day. If you are moving from spreadsheets or another tool, our team provides import templates and checklists, and larger companies can add guided implementation.
