Know where the job stands before the job is finished

Construction and field businesses discover their margin at the end, when the job is closed and the numbers are added up. By then every decision that determined the outcome has already been made. We build the visibility that moves that discovery forward — to the week the cost is incurred, not the month after the job completes.

The sector

Technology in this sector buys you time to react

A job that will lose money usually signals it early — in labour hours drifting past the estimate, in materials drawn faster than planned, in change work performed before it was priced. The information exists on the site; the office receives it weeks later on a paper ticket. Closing that lag is what technology is for here, and each sub-sector closes it differently.

General contractors

Project delivery, subcontractor management, change orders, progress billing and the retention and lien administration that dominates cash flow.

Specialty & trade contractors

Crew scheduling across many small jobs, service and project work mixed together, and material and truck stock management.

Mechanical, electrical & plumbing services

Preventive maintenance contracts, emergency dispatch, equipment history at each site, and the contract renewals that make a service book valuable.

Field service & installation

Technician scheduling with skills and parts, first-time fix rate, warranty and returns, and the customer communication that determines a review score.

Facilities & property services

Multi-site work orders, service level agreements, planned and reactive maintenance, and reporting to property owners who want evidence, not assurances.

Infrastructure & civil

Multi-year projects, equipment and plant utilisation, certified payroll and prevailing wage, and the funding compliance attached to public work.

Where the return actually comes from

Where the return actually comes from: Three sources dominate. Change orders: work performed but never priced or billed is, in most contracting businesses we see, the single largest recoverable leak — and it is a process problem, not a commercial one. Utilisation: an extra job per crew per week compounds enormously across a year, and most scheduling is done from a whiteboard and a memory of who is where. And cash: progress billing raised promptly against actual completion, with retention tracked, shortens a cycle that most contractors finance out of their own working capital.

The software this sector runs on

The systems a contracting business runs on

This sector is the most paper-dependent we work in, and the gap between site and office is where most of the value is trapped.

Financial

Job costing, accounting and payroll

Job cost accounting, progress billing, retention, certified payroll and equipment costing. Construction accounting is genuinely different from general accounting, and generic systems handle it badly.

Operational

Project management, scheduling and dispatch

Crew and technician scheduling, dispatch, work orders, project sequencing and subcontractor coordination — most often run on a whiteboard, a phone and a great deal of institutional memory.

Field

Mobile capture, time and documentation

Time entry, material usage, photographs, signatures, inspection forms and daily reports captured at the point of work — and, crucially, working when the site has no connectivity.

Commercial

Estimating, bidding, contracts and change orders

Estimating, bid management, contracts, change order pricing and approval, and the customer communication that stops a variation becoming a dispute six months later.

Challenges

What contractors and service leaders raise first

Four problems, and the outcome the owner or operations director is really asking for.

01

Change orders are performed before they are priced

A customer asks for something on site. The crew does it, because saying no is awkward and the relationship matters. The paperwork follows sometimes, is priced optimistically, and is disputed at the end.

The outcome leaders ask forEvery variation captured on site at the moment it is requested, priced against the contract and approved before the work starts — recovering revenue that is currently written off as goodwill.
02

Job cost arrives after the job is finished

Labour tickets, material invoices and equipment charges reach accounting on their own timetable. A job is understood in the month-end close, by which point nothing can be changed.

The outcome leaders ask forWeekly job cost against budget, with the projected final position updated as costs land, so a drifting job is addressed while there is still job left to fix.
03

Scheduling depends on one person's memory

Who is on which job, with what skills, holding which parts, and what happens when someone calls in sick at 6am. It works until that person is on holiday.

The outcome leaders ask forCrew and technician scheduling against real availability, skills and location, with the day's plan visible to everyone and reschedulable in minutes rather than by phone tree.
04

Paper leaves the site and does not come back

Daily reports, timesheets, delivery notes and photographs are captured on paper, and some proportion never arrives. What is lost is exactly what would have won the dispute.

The outcome leaders ask forEverything captured digitally at the point of work, working offline, synced when the device reaches signal — so the evidence exists when it matters.

Every one of these is a lag problem rather than a knowledge problem. The site already knows. The question is only how long the office takes to find out, and whether it is still early enough to act. Every one of these is a lag problem rather than a knowledge problem

How we help

Three ways we work with construction and field businesses

Almost everyone starts with the field capture, because it is the fastest way to make everything else possible.

Field operations and mobile capture

The site end: time, materials, photographs, forms and signatures captured where the work happens, offline when necessary.

  • Mobile time and material capture, offline capable
  • Photographic evidence attached to the job
  • Daily reports and inspection forms
  • Customer signature and proof of completion

Job costing, change orders and billing

The commercial engine: budget against actual while the job runs, variations priced properly, and billing raised promptly.

  • Job cost against budget updated weekly
  • Change order capture, pricing and approval
  • Progress billing and retention tracking
  • Projected final cost and margin per job

Scheduling, dispatch and service contracts

The resource engine: the right crew, with the right skills and the right parts, at the right site.

  • Crew and technician scheduling by skill and location
  • Emergency dispatch and re-scheduling
  • Preventive maintenance contracts and renewals
  • Equipment and asset service history by site
Our approach

How we learn a contracting business before we design anything

We start on site. Designing field software from an office is the most reliable way to produce something crews refuse to use.

1

Go to site

We spend days with crews and technicians, watching what gets captured, what gets lost and why.

2

Align

We agree outcomes with ownership, operations and accounting together, and define the margin metric precisely.

3

Design

We prototype the mobile experience first and put it in the hands of a real crew before building anything else.

4

Implement

We roll out field capture first, prove it with one crew, then extend to costing, billing and scheduling.

5

Optimize

We measure margin, change order capture and utilisation against the baseline across a full season.

The crew that will be hardest to convince should be in your pilot group, not protected from it. If the app works for them it works for everyone, and if it does not, we would rather know in week three than after a company-wide rollout.

Why JJC Systems

Why contractors choose JJC Systems

Field software fails for one dominant reason: it was designed for the office and given to the site.

We design for the site first

Gloves, sunlight, cracked screens, no signal and someone who wants to be back in the truck. If capturing a timesheet takes more than a minute, it will not happen and none of the reporting above it will be true.

We understand construction accounting

Job costing, work in progress, retention, progress billing and certified payroll behave differently from general accounting. Generic implementations get this wrong and the finance team discovers it at year end.

We connect estimating, field and accounting

The value is in the loop: what you estimated, what it actually cost, and what that should change about the next bid. Most systems break that loop at the first hand-off.

One partner from the truck to the ledger

Mobile devices, connectivity, applications and the managed service from one accountable team — which matters when a crew cannot log in at six in the morning.

Customer success

What good looks like in construction and field services

Two illustrative engagements showing the shape of the work.

Specialty contractor

Change orders stopped being written off as goodwill

Crews performed extra work requested on site and the paperwork followed inconsistently. The owner estimated the annual write-off but had never been able to measure it.

83%Change orders now captured
5.2 ptsJob margin improvement
Same dayVariation priced

What changed

  • Variation captured on the mobile app at the moment the customer asks
  • Priced against contract rates and sent for approval before work begins
  • Customer signature captured on site, ending disputes at close-out
  • Annual write-off finally measured, then substantially reduced

Mechanical services company

Scheduling that survived the dispatcher's holiday

One dispatcher held the entire schedule in her head and a whiteboard. Technician utilisation was unknown, emergency work displaced planned maintenance unpredictably, and holidays were genuinely stressful.

17%Higher utilisation
+1Job per tech per week
0Whiteboards

What changed

  • Scheduling by skill, location, parts availability and contract priority
  • Emergency dispatch reshuffling the day without losing planned maintenance
  • Technicians seeing tomorrow's work the night before, with site history attached
  • Contract renewals prompted automatically instead of remembered
