One system from the quote in the customer’s kitchen to the balance on delivery.
Operations management for the building trade. Contractors, installers and trade suppliers across the sectors that build, fit out and maintain Scotland’s building stock. Enquiry to invoice in one place, the documentation that has to match the work, and the analytics the directors actually use.

In the customer’s kitchen
A salesperson stands in a customer’s bathroom with a Pencil and no signal. Tradilus treats the iPad as the paper order form it replaces — a ruled pad you write on — and keeps the two things that cost money when missed, the sync state and the contract number, permanently on the page.
A ruled ledger for the customer, the specification in the salesperson’s own handwriting — recognised into text with the ink kept on the order — and the money column never out of view. VAT inclusive or exclusive changes the arithmetic, not just the label.

Squared paper across the whole glass, not a locked box. Sketches and photographs sit beside the specification rather than under it, carry a typed caption so they can be searched, and print on the customer’s copy in the order they appear.

The signature box stays locked until the terms have been scrolled to the end — visibly locked, not silently dead. The time the terms were shown and the time they were read to the end are both stamped on the order.

The company’s house rule worked out live — 30% of £4,331 is £1,299, and £1,300 clears it. The card machine is driven from the iPad; the app never sees the card number, only the amount, the last four digits and the auth code recorded against the order.

An amendment creates version 2, which is not in force until the customer signs it again. Version 1 stays the agreement in the meantime, the deposit carries over untouched, and if the customer refuses the change nothing is lost.

Everything is written to the iPad first and sent second. A block of contract numbers is held on the device so orders can be numbered without a connection, and the queue shows exactly what is waiting — nothing in it can be lost by closing the app or running the battery flat.

What you get
Built for the trade where the order is agreed in somebody’s house, the deposit is taken on the doorstep, and the fitter turns up three weeks later expecting the paperwork to match.
Pencil first. Handwriting becomes text and the ink is kept; sketches get the whole glass; every value is written at a size meant to be written, not read. The paper form’s rhythm, with the arithmetic done for you.
The gate, the progress bar, the two timestamps. Every order keeps the version of the terms it was signed under — publishing new terms changes nothing already agreed — and amendments are versions, never edits.
Dojo on the iPad for the deposit, the balance on delivery visible to the office the moment it syncs, and a bank transfer that lands while you are out matched to its order by the contract number on the statement.
Written locally first, sent when there is a connection. Contract numbers held on the device in blocks. The sync state is permanent chrome on every screen, not a toast that disappears before anyone reads it.
The office
The same orders, on a desk browser, a showroom iPad and a phone in a van. Sorted by what needs doing rather than by date: an amendment waiting on a signature sits above an order that closed in June.
The showroom iPad opens on the day, not the week, with hit targets sized for standing at the trade counter. The phone answers four questions and refuses the rest — anything that changes what the customer agreed to happens on the iPad, in front of them.
The runs in time order, money to collect on the right, the one decision pinned at the top.
What someone needs when a customer rings: the balance, then the two buttons that do something about it.
A bank transfer that landed while you were out, matched to its order by the reference on the statement.

Built for your trade
The quote-to-install build above sells bathrooms and fire surrounds. The same engine runs MGN Fire Protection — enquiry to invoice, drawing-linked compliance records, subcontractor tracking. Pick the closest and we shape the build around how your trade actually works.
The order written in the house, the deposit on the doorstep, the fitter booked with the goods.
Survey, sketch, specification and install on one order, under the company the customer bought from.
Drawing-linked compliance records, subcontractor tracking, the documentation that has to match the work — the MGN build.
Measured on site, priced on the pad, signed before the survey leaves the house.
Areas sketched and captioned, batch notes on the order, fitters allocated by skill.
Enquiry to invoice, certificates on the job, the balance collected when the work is signed off.
Collections from the counter, account customers, the office iPad sized for standing up.
If the job is agreed in one place and done in another, it fits. Tell us the shape and we will map it.
FAQ
Anything else, ask on the demo. We answer with the product open, not a slide deck.
That is the case it is built for. Orders, signatures and payments are written to the iPad first and sent when there is a connection. Contract numbers are held on the device in blocks, so an order can be numbered and signed with no signal at all.
The signature strokes, the time the terms were displayed, the time they were scrolled to the end, and the version of the terms in force that day. The signature surface is inert until the terms have been read through, so a signature cannot exist without that record.
An amendment creates version 2 with the changes marked line by line and the reason written by whoever agreed it. It is not in force until the customer signs it again; version 1 stays the agreement meanwhile and the deposit carries over. If they refuse, version 2 is discarded and nothing is lost.
Every payment sits against its order with the method, auth code or bank reference. The office exports a CSV by period — contract, customer, net, VAT, gross, paid, balance, method, version — with amendments as their own rows.
