Why Auromis exists

Subcontractors do the work first and wait to get paid. Auromis exists so you always know what every main contractor owes you, what’s held back and what’s due next.

Where cash gets stuck

The everyday gaps between applying for payment and being paid.

  • Retention in two halves

    Half due at practical completion, half at the end of the defects period, and both easy to lose track of.

  • Notice dates kept in your head

    Payment and pay less notice dates decide what’s due, but they’re often kept in someone’s head.

  • Short payments spotted late

    Gaps between what you applied for and what was paid, found at month-end or not at all.

  • Variations applied for late

    Variations and compensation events applied for late, or never.

  • Letters written from scratch

    Every reminder and release request typed again, for every main contractor.

  • Portal data keyed in by hand

    Figures re-keyed from portals and spreadsheets into yet another spreadsheet.

What we believe

On top of your tools

Auromis reads the files you already have. Nothing to replace, no migration.

Every number has a source

Each figure links to the document and line it came from. AI reads; plain code adds up.

You decide what goes out

Letters are drafts. You review them and send them yourself, when you choose.

Flat, published prices

A free plan and flat monthly prices. Never a percentage of your turnover.

Self-serve, no sales calls

No demos and no sales calls. Upload your files and see your numbers.

Rules with citations

Dates come with the section of the Act or contract clause behind them. Information, not legal advice.

Where we work

One engine, three country packs, each with its own documents, rules and words.

  • United Kingdom

    Specialist subcontractors working for main contractors. Construction Act notice dates and retention, for England and Wales.

    UK site

  • United States

    Commercial specialty subcontractors and the bookkeepers who bill for them. State rules for 18 states.

    US site

  • Germany

    Finishing-trade subcontractors billing general contractors, developers and public clients. VOB/B deadlines, retentions and guarantees.

What we don’t do

  • No portal logins

    We never log in to, scrape or submit to contractor portals.

  • No money handling

    We never hold, move or lend money.

  • No legal advice

    We show dates with sources. For disputes or adjudication, speak to a construction solicitor or claims consultant.

  • Nothing sent without you

    Letters are drafts. You review them and send them yourself.

  • No software replacement

    Keep Xero, Sage or your ERP. We read their exports and replace nothing.

  • No promised outcomes

    We show what’s due and when. We never promise how a payment or a dispute will end.

Start with one month of applications.

We read them and send back what every main contractor owes you, what they retain and what falls due. No sales call. No demo.
