Bijection for Financial Services

Four eyes in the change. Not in an inbox.

When an auditor asks who approved an override, the answer is the change itself.


An override approved by email, a break cleared in a spreadsheet, a client file assembled from four systems the week before an audit. The core systems are right; the work around them is where the evidence goes missing.

Bijection reads your core systems without replacing them, and moves the work around them into reviewed changes. A change applies only after a second person approves its exact effects, and the author, inputs, effects and approver are recorded together.

  • Limit overrides

    Starts: A trader requests a temporary limit increase

    1. The request shows current exposure and the override’s effect.
    2. A second person approves the exact change.
    3. The override expires on its own at the end date.
  • Reconciliation breaks

    Starts: The nightly reconciliation finds a difference

    1. Each break becomes a record with both sides attached.
    2. An analyst proposes a resolution.
    3. Clearing it needs a reviewer, and the evidence stays with the break.
  • Client reviews

    Starts: A client’s periodic review is due

    1. Assemble holdings, agreements and missing documents.
    2. The review waits for the relationship manager’s sign-off.
    3. Overdue reviews stay visible until they are signed.
  • Client onboarding

    Starts: A new client signs

    1. Collect identity documents and agreements.
    2. Each missing item waits for its owner.
    3. The account opens once compliance approves.
  • Trade corrections

    Starts: Someone amends a booked trade

    1. Show the original, the correction and the effect on positions.
    2. A second person approves.
    3. The correction is sent to the booking system and recorded.
  • Regulatory reports

    Starts: A reporting deadline approaches

    1. Assemble the figures from the core systems at one cut-off.
    2. Each figure keeps its source records.
    3. The report waits for sign-off before it is submitted.
