A tradesman app for jobs, quotes and invoices
Call it a tradesman app, an app for tradesmen, tradesmen apps, tradesman apps, a job management app for tradesmen or a field service app — Opsler runs your customers, jobs, quotes and invoices from one app you install straight from the browser. Two seats are free forever, and there is nothing to download from a store before your first job goes on the board.

Install it from the browser and hand it out with a link
Open Opsler in a supported browser on your phone, tablet or laptop and install it from there. It launches from its own icon and runs full-screen, exactly like any other app on the home screen.
What that changes day to day is onboarding. A new lad starts Monday and you send him a link — no store search, no account approval, no waiting on a download over a site 4G signal. Everyone runs the current version the moment they open it, so nobody is filling in last month’s job card because their phone never updated.
Who the app is built for
A sole trader or a small trade team running enquiries, quotes, a diary and invoices from a phone and a laptop is squarely who this is built for. One van or eight, the shape of the day is the same: work comes in, it gets priced, it gets booked, somebody does it, somebody bills it.
Opsler is built around that loop rather than bolted onto it, which is why it takes an afternoon to adopt rather than a quarter.
Capture enquiries and customer details
A new enquiry becomes a customer record with a service address and job history attached, so the next call from that customer isn’t a blank page. However the enquiry arrives, it goes through the same request workflow before landing as a job on the schedule.
Create and manage quotes
Build a quote from your own price book — a single price, or three tiers when the job is big enough to be worth a choice — and the customer approves it with a one-time code emailed to them plus a signature, typed or drawn, on one page in their own browser. No account to create, nothing to install at their end.
What comes back is a dated signature against a specific figure, and a yes turns into a job on the board with the approved lines already attached. The price the customer agreed to is the price they get billed, because nobody retyped it in between.
View the diary and assigned jobs
A drag-and-drop board shows every job assigned to you or your team for the day or week ahead, so a tradesman working alone can see the whole week at a glance from the same app used to quote and invoice.
Use a digital job card in the field
The job card carries the address, notes and customer history to wherever you open the app, and photos, time and materials log against that same record as the work happens.
Finish the job and bill it where the signal isn’t
Plant rooms, basements, lofts, farm tracks. The places the work is are reliably the places the bars aren’t, and that is exactly where an app usually stops being any use.
Opsler keeps going. Open the job you were assigned, work through its checklist, take the before and after photos, write your notes, move the status, get the customer to sign, raise the invoice and take the payment if they offer a card. It all holds on the device and syncs itself the moment coverage comes back.
The point of that is not the technology. It is that the job is finished when you leave, not when somebody finally sits down with a laptop — and an invoice raised on the doorstep is paid days before one raised on Sunday night.
Keep office and field records visible to the right people
Whether you’re working solo or with a small team, the same job record is visible from the office view and the field view — nobody is reading a different version of what happened on the job.
Plan the day in the right order and drive less of it
Route optimisation is built in. Give Opsler the day’s work and it puts the stops in a sensible order, so the van stops criss-crossing the same three postcodes and the hours you were losing between jobs turn back into jobs.
The office sees the day move without ringing anyone. On the way, arrived, done — it lands as it happens, so whoever is answering the phone can tell a customer when someone is coming instead of promising to find out and call back.
One extra job a week, at whatever your average ticket is, pays for the whole team’s seats several times over. That is usually the cheapest growth available to a small trade business — it needs no new customers at all.

Tradesman app questions
It depends whether you want a native phone app from an app store or a browser-installed one that runs on any device without a download. Opsler is the second kind: install it straight from a supported browser on your phone, tablet or laptop, and it behaves like an app icon from there. If enquiries, quotes, a diary, job cards and invoices are your bottleneck, that is exactly what it is built for — worth testing on a real job before deciding it fits.
In Opsler, the part that decides whether your day works: open the job you were assigned, run its checklist, take before and after photos, add notes, change the job status, get the customer's signature, raise the invoice and record the payment. All of it holds on the device and syncs by itself when coverage comes back. A basement, a plant room and a valley with one bar all stop being a reason for paperwork to pile up until Friday.
No — and that is the point. Install Opsler straight from Safari, Chrome or another supported browser and it runs full-screen from a home-screen or desktop icon on a phone, a tablet and the laptop in the office. New starters are working within a minute of being sent a link, there is nothing to keep updated on eight different devices, and you never have to talk somebody through an app-store search from the side of a road.
