Decision guide

When your accounting is enough — and when it is not

The built-in features are a good start. A planning tool of your own pays off as soon as you want to steer with the plan.

Your accounting is enough if …

you run one company with few accounts, the bank balance and the open items are enough for you, and you only want to look a few weeks ahead.

A planning tool comes in if …

you want to plan by your own priorities, calculate scenarios, hold the plan against the actuals or see several entities together — or your bank wants to see a cash flow plan.

And from plan to payment

In COMMITLY you approve supplier invoices and pay them in the same system — as a SEPA XML file, via Pay by Bank or EBICS. Your accounting receives the approved invoices back.
