Job management software for installers: fire, security, lighting and renewables
In short
Installers who quote, buy and commission projects need the job record to hold the quote, purchase orders and sign-off forms, which a field-service scheduler does not. Shortlist by asking each vendor to rebuild your last install live, from quote to final invoice.
Field-service apps schedule engineers, but installers who quote, buy equipment and commission projects need the job to hold the quote, purchase orders and sign-off forms. Here is how to shortlist the right class of system.
An installation business needs job management software where the job record holds the quote, the purchase orders, the delivery notes, the invoices and the signed commissioning paperwork, not just a visit in an engineer's diary. A field-service app schedules and dispatches people. An installer who quotes, buys equipment and has to prove the work was commissioned needs a system that follows the money and the paperwork from quote acceptance to final invoice. Zigaflow is built for that second job. It is not built to be a dispatch board.
Two different problems with the same name
"Job management" covers two products. The first is field service software: a calendar of visits, engineers assigned to them, routes, and a mobile app to close each visit. It answers "who is going where on Tuesday?" and does that well.
The second answers a different question: "what did we sell, what have we bought for it, what has arrived, what has been signed off, and what can we invoice?" For a reactive repair business the first question is the whole business. For a fire alarm, CCTV, lighting or solar installer, it is the smaller half. The value of the job sits in a quote with a bill of materials, equipment ordered from several suppliers, staged delivery, and a certificate at the end.
If you pick a scheduling tool for that business, the engineer turns up on time and the margin still leaks. Costs land in a supplier inbox, the quote lives in a different system, and the commissioning certificate is a PDF on someone's laptop.
What the job has to hold
Use this as your shortlist test. Ask any vendor to show you one live job and check that it carries all of the following.
The accepted quote. The job should be created from the quote with items, pricing and costs already in place. Zigaflow's Jobs module converts an accepted quote to a job in one click, so the forecast cost you priced is the baseline for the job.
The purchase orders. Installers buy panels, detectors, luminaires and controllers from several suppliers. You want purchase orders raised from the job, with the expected delivery date visible on the job. Zigaflow lets you create purchase orders for multiple suppliers from the job and shows forecast cost beside actual cost from purchase orders and inventory allocation, so a supplier price rise shows up while the job is live.
Part deliveries and part invoices. Installations rarely go in on one day or bill on one day. The job should show what has been delivered and what has been billed, down to line level, and allow deposit, progress and final invoices.
The sign-off. This is where field-service tools usually stop. Commissioning certificates, test results, serial numbers, photos and customer signatures need to attach to the same job. Zigaflow eForms can be generated from any job, pre-filled with job details, sent by link with automatic chasing, and filed on the job as a date-stamped PDF with up to two signature fields. Recipients need no account or app.
What this looks like in the trades
A fire and security contractor has detector and panel orders, a certificate at handover and often a maintenance contract afterwards. The fire and security pages cover how that plays out for alarm, CCTV and sprinkler work. Indigo Fire Systems, a sprinkler contractor, replaced spreadsheets of about 50 tabs per project with one connected system, starting with purchase orders and adding modules from there. Its team describes job costs finally going against the jobs.
A lighting project has a specification that changes after the quote, long-lead fittings and emergency lighting certification. A renewables installer has a survey, a grid or commissioning milestone and a handover pack. In all three, the paperwork is not an afterthought. It is the thing that unlocks the last invoice.
What Zigaflow does not do
Be plain about the limits when you shortlist. Based on the Jobs and eForms pages, Zigaflow assigns team members, sets deadlines per job, and shows jobs on a kanban board filtered by customer, value, team member or delivery date. Those pages do not describe a route-optimized dispatch calendar or live engineer tracking. If your main pain is sending forty engineers to reactive calls, put a field-service tool on your list and judge Zigaflow as the commercial layer, not the dispatcher. It also sits between CRM and ERP rather than replacing your accounts package; invoice and payment data syncs to Xero, QuickBooks or FreeAgent.
What it costs
Pricing is published, in pounds sterling and excluding tax. Essentials is £79 a month, Go £199 and Momentum £399, with extra users at £69, £79 and £89 respectively. Quotes, Jobs, Purchase Orders, Delivery Notes and Invoices are on every plan. The pricing table lists eForms and RFQs under Momentum, so check that detail first if sign-off forms are your priority. Every plan includes a one-hour onboarding session.
How to run the shortlist
Take your last completed install and ask each vendor to rebuild it live: quote, three supplier orders, a part delivery, a commissioning form, a staged invoice. Count how many separate screens or systems you needed. If the answer is more than one, you are buying a scheduler and will still be running the commercial side in spreadsheets.
