We build the machinery, not the accounts.

Deuteronomy Consulting builds and runs finance systems for contracting and field-based businesses, and makes Ordine.

We started because of a pattern that shows up in nearly every growing contractor. The finance function was designed for a smaller company. Nobody had time to redesign it. And the cost of that shows up as money going out twice, and jobs priced on optimism.

Most consultancies would tell you that’s a discipline problem. It isn’t. It’s a systems problem, and it responds to systems.

What we are building sits between two worlds that rarely meet properly: finance, and the technology that should be carrying it. Ledgers, approvals, costing and reporting are all still done by hand in most contracting businesses, not because anyone chose that, but because nobody has ever come in and joined the two together.

That is the whole business. Your accountant does the accounts. We build the machinery that feeds them, and the reporting that tells you what is happening while there is still time to do something about it.

Who’s behind it

Deuteronomy was founded by a finance systems consultant who spent years embedded in the finance function of a utilities and civils contractor — running the purchase ledger, subcontractor billing, the deductions, the month-end — and who built, alongside that, the automation that took most of it off the desk: fleet data pipelines, approval routing, a job-pricing model, dashboards for directors, and the day-sheet system that has paid a subcontractor workforce every week since April 2025 — seven versions on.

That is where Ordine comes from. It was not designed in a workshop; it was built inside a business that needed it, against real money, and then rebuilt cleanly as a product with the lessons kept and the shortcuts removed.

Why we work differently

Most people who understand finance can’t build systems. Most people who can build systems have never sat inside a finance function and felt what is actually wrong with it.

We come from both sides. We know which numbers matter because we have had to produce them by hand, to a deadline, with someone waiting. And we can build the thing that produces them without anyone touching it. So instead of a better process for someone to follow, you get the process removed.

The aim is always the same: less grunt work, fewer hands touching the same figure, and information that arrives early enough to change the decision.

How we work

• Fixed prices, scoped in advance. No hourly billing, no open-ended discovery, no invoice you couldn’t have predicted.
• We tell you what we can’t do at the first meeting, not the fourth.
• Your records stay yours. Your accounting system is your statutory book; everything we build exports on demand. If you stop working with us, you lose the tooling, not the data.
• We work alongside your accountant, not instead of them — and we’ll tell you when something needs to go to them.
• We build things to run without us. A system that needs its builder standing next to it isn’t finished.

Where we work

Construction, civils and utilities is where we’re strongest — subcontractor billing, job costing, retentions and applications for payment are a particular kind of mess and we know it well. Ordine carries that knowledge into M&E, fleet-heavy and project-based businesses through industry presets.

We work UK-wide. Most of what we do runs on your systems rather than in your office, so distance rarely matters. We’ll come to you at the start of an engagement and whenever it earns its place; the rest happens remotely.
