    Finance ops

    The numbers your filings are built from.

    Every return you file is assembled from invoices, payments and ledgers. Keeping those in a separate system from the obligations they feed is what makes month-end an archaeology exercise.

    The handoff is where the errors are

    Books live in one place, filings in another, and the two are reconciled by a person copying figures across under time pressure. Every one of those handoffs is a chance for a number to change silently between the ledger and the return.

    What it does

    Invoices and billing

    Raise invoices in a GST-correct format, track what is owed, and keep the record attached to the entity it belongs to.

    Clients and vendors

    One list of who you bill and who bills you, with the documents and filing status that matter for input tax credit.

    Reports that match the returns

    Reporting built from the same records the filings draw on, so the figures do not diverge between systems.

    In the same system as the calendar

    The books and the obligations they feed sit together, which is what makes reconciliation continuous rather than a month-end event.
