01Overview

A multi-currency account for people paid in one currency and living in another: one balance, the rate they were quoted, and no fee that arrives later.

02The problem

Aurel launched with a wallet per currency. A customer holding four currencies had four balances, four histories and no idea what they were worth together. Conversions quoted one rate and settled at another, and the difference surfaced on a statement days later.

03What we built
  1. 01

    One ledger, many currencies

    The account is a single double-entry ledger with a currency dimension. Balances, conversions and card charges are entries in one history rather than transfers between wallets.

  2. 02

    The quoted rate is the settled rate

    A quote is a held commitment with the fee shown as its own line before the customer confirms. If the market moves inside the hold, Aurel absorbs it and the treasury desk sees that exposure live.

  3. 03

    Insight nobody asked for

    Spending is categorised on the device and compared with the same month last year. The summary names the two things that actually changed, in Arabic or English, in one sentence each.

04The result

Customers stopped keeping a second app for conversions and support stopped explaining arithmetic. Multi-currency balances became the default rather than a workaround.

Closing

Do you have an idea, or a problem?

Either works. In my experience the second one goes faster.

I usually reply the same day.
