The paperwork between the job and the invoice
In most firms there is a pile of paper between the work being done and the invoice going out. Hours on a pad, materials on a delivery note left in the van, a photo on the engineer's phone. At the end of the month somebody in the office reconstructs what happened. Whatever gets lost in that reconstruction never makes it onto an invoice.
The mechanism is simple: every re-entry is a chance to lose something. Take out the re-entries and nothing goes missing.
What hangs together
Quotes and variations
Quotes with provisional sums, and variations signed off before the work starts rather than argued about after.
Scheduling
Drag a job onto the week and the engineer sees it on the phone. No WhatsApp group.
Job sheets on site
Hours, materials and photos captured on site, signed by the customer on the phone.
Invoicing without rework
What was captured is already there when you invoice. Nothing to retype, nothing forgotten.
Who it is for
Firms with engineers out on the road: plumbing and heating, electrical, roofing, joinery, renewables. From about three people on site, coordinating starts to cost more time than the work itself, and a shared system starts paying for itself.
If you work on your own, most of this is overhead. That is what the smallest plan is for.

Does this replace my accounting software?
No. Quandron takes you as far as the invoice and hands the data over; the books stay with your accountant or your accounting package. There is a CSV export in the Xero import format from day one, and a plain CSV that any package will take; direct links come later.
Does the app work without signal?
Sites are often short of signal. Hours, photos and signatures are stored on the device and sent as soon as the connection returns.
Can it handle CIS?
That has a page of its own, because it changes what an invoice looks like rather than being a setting.
How long does setting up take?
You can raise the first job the same day. What takes time is the existing data: customers, price lists, jobs in progress. How that moves over depends on the shape it is in today.
