Door 04 — Systems

The machinery behind the counter.

Software that runs the boring parts: jobs, invoices, payments, reminders, reviews. Wired once, working every day, with your name on the paperwork.

Job management / ERP

Projects, estimates, invoices, site photos, schedules, subcontractor packs — one workspace instead of a van full of paper.

Client portals

Your customers log in, raise requests, see invoices, update payment details, sign contracts. Fewer calls, everything written down.

Payment collection

Stripe links, QR codes on invoices, deposits, GoCardless direct debit for contracts. Money in on time, without the awkward chase.

Ordering & booking engines

Bookings, quote calculators, online ordering — customers serve themselves, you get the notification.

Automations

Missed-call text-back, reminders, follow-ups, review requests. The jobs nobody remembers, done every time.

Branded document pack

Invoice, quote and job-tracker tools with your VAT logic, numbering and bank details built in. Documents, not legal advice.

How it works

Talk

Walk us through a normal week — where the paper piles up, where the money leaks. That's the spec.

Build

We wire the system and load your real jobs, prices and templates. Your team tests it before it ships.

Run

Hosted, backed up, monitored. One monthly cost. When your business changes, the system changes with it.

Straight answers

Is this off-the-shelf software?

It's our platform, shaped to your trade — your paperwork, your branding, your flow. You get the fit of custom without the custom price.

What does it cost to run?

A flat monthly figure quoted with the build — hosting, backups, monitoring and support included. No per-seat surprises.

What happens to my data if I leave?

It's yours. We export everything in usable formats and shake hands.

Can it talk to my accountant?

Yes — exports and reports built for handover. If your accountant is Roseworth next door, even easier.
