Why Auromis exists

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

Self-serve, flat pricing, and nothing sent without you.

What we hear from subcontractors

From the public posts and comments by subs, billers and bookkeepers that we studied before building Auromis.

  • Waiting to get paid

    Slow pay and pay-when-paid come up more than anything else when subs talk about getting paid.

  • Retainage held for months

    The work is finished, but retainage sits with the GC for months, tracked in a tab nobody updates.

  • Change orders that slip away

    Approved work that never gets billed, or disputed change orders given up by signing the wrong lien waiver.

  • Deadlines found too late

    Lien and notice dates that pass before anyone in the office notices.

  • A different portal per GC

    Several portals, each with its own forms and cutoffs, and none of them shows the whole picture.

  • Pushing feels risky

    Many subs don’t chase hard for fear of losing the next job. Quiet, accurate records help without picking a fight.

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 billing.

Self-serve, no sales calls

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

Rules with citations

Deadlines come with the statute 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.

What we don’t do

  • No portal logins

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

  • No money handling

    We never hold, move or lend money.

  • No legal advice

    We show rules with citations. For disputes, talk to a construction attorney.

  • No lien filing

    We flag deadlines and help you prepare your evidence. Filing is up to you and your attorney.

  • Nothing sent without you

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

  • No ERP replacement

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

Start with one month of pay apps.

We read them and send back what every GC owes you, what they hold and what falls due. No sales call. No demo.
