03App Development

The workbook that breaks when two people open it.

Plenty of businesses run dispatch, pricing or the schedule from one workbook that one person fully understands. It works until two people need it at once, or someone needs it in the van. We turn it into an app with logins, a history of every change, and a phone screen the crew can use.

The rest of what separates the app from the workbook isn’t a number, so it isn’t drawn here: logins, two people in it at once, and everything readable while the van has no signal, with changes held on the phone and synced when it reconnects.

What the work is

Six things, and what each one gets you.

01

Custom app development

The same records the workbook holds, with logins, permissions and a history on every field. Nobody has to remember not to sort the sheet while someone else is typing in it.

02

UI/UX design

Two views of one set of records. The office gets the board it needs. The crew gets big buttons and no tables, sized for a phone used outdoors.

03

iOS and Android development

On the phones your people already carry, usually as a web app they install from a link, so a bug fix never waits in an App Store review queue. We test on a mid-range Android with a weak signal, because that’s the phone it’ll run on.

04

Integrations with what you already run

A job that gets invoiced lands in your accounting package without anyone retyping it, and the schedule the office changes is the schedule the crew sees. If something won’t connect, you hear about it in week zero.

05

QA and testing

Including the awkward case: two people editing the same job while one of them has no signal. Everything stays readable offline, changes wait on the phone and sync when it reconnects, and a test proves it.

06

Support and maintenance

Optional. The app runs in your own cloud account, your data exports to CSV whenever you want it, and nothing stops working if you stop paying us.

What it costs and how it runs

$18,000 to $40,000 to build, and you own it.

Build$18,000 to $40,000 depending on how much the workbook does. Yours varies with the project, and the price is fixed once quoted
Running$60 to $220 a month, on your own cloud account
Us, after$0. No retainer and no licence. Support is there if you want it, priced per piece of work
Not includedRugged devices, if you decide you want them, and any per-seat licence you don’t already hold. Everything else is in the fixed price
Week 0

We read the workbook

Every sheet, including the ones nobody mentions and the hidden columns. The rules that live in someone’s head get written down here, and that’s often the most valuable week of the project.

Weeks 1 to 6

The office view first, beside the sheet

The workbook stays in use the whole time. Nothing moves over until the app has handled the same week of real work and given the same answers, twice.

Weeks 7 to 9

The crews, on their own phones

The field view ships after the office view, to the people who’ll use it on site. Week nine runs both side by side, then the sheet goes read-only.

Questions about this one

What people ask before they start.

The spreadsheet works. Why replace it?
Maybe you shouldn’t. A workbook usually stops being fine for one of three reasons: two people need it at once, someone outside the office needs it, or you need to prove what a field said four months ago. If none of those apply, keep it and spend the money elsewhere. If two do, you’re already paying for it in retyping and arguments.
What happens to the years of history in it?
It comes with you. We import the sheet as the starting point, including the rows that break the rules. Anything that won’t import cleanly goes on a list for you to decide about, so nothing disappears without you knowing.
Our crews aren’t technical, and half of them dislike change.
That’s the usual starting point, and it’s why the field view ships second, after the office view has proved the records are right. The crew gets three taps to arrive, photograph and close. No tables, no training day, and it keeps working with no signal.
Why does this cost more than an off-the-shelf app?
An off-the-shelf app is built for the typical company. If one fits you, buy it, and we’ll point you to it. Here you’re paying for an app shaped like your business, running in your own account, exporting whenever you ask, with no seat count to renegotiate at renewal.
