When your bank and your bookkeeping are the same system

There’s a category of bookkeeping software that’s also a bank. Moneybird has it. A few others too.

The appeal is obvious: transactions appear in the bookkeeping immediately. No connection, no sync, no middleware. You pay with the card, it lands in the ledger. Automatic invoicing, iDEAL payments, recurring billing — all inside one product.

For a solo freelancer with straightforward cash flow, this is genuinely clean. The friction that most bookkeeping setups have — the connection that goes down, the MT940 you forgot to import, the reconciliation that lags two days — just doesn’t exist.

The tradeoff is lock-in.

Your banking is now tied to your bookkeeping vendor. If you want to switch bookkeeping tools, you also need to migrate your bank account. That’s not a five-minute process.

There’s also a less obvious issue: when your bank and bookkeeping are the same product, the system knows everything. That’s useful. It’s also worth being thoughtful about from a data perspective — especially if the business grows, adds complexity, or needs to connect to other financial systems.

For most small Dutch businesses just starting out, the integrated path is probably fine. The simplicity is real and the automation benefit is real.

What I’d keep in mind: think about where the business is going, not just where it is today. If you expect to add a Mollie payment flow, a WooCommerce sync, a payroll integration — check whether the all-in-one product supports those connections before committing to it as your banking infrastructure.

The simpler the setup, the easier it is to outgrow.
