Short answer
MoneyMonk is a Dutch bookkeeping package for freelancers built around time tracking and project administration, with plans from €0 (Starter, free for 15 months) to €37.50 a month and a 30-day free trial. What makes it unusual is that your plan moves with your turnover: the three cheaper plans (Starter, Basis and Pro) limit both the number of bank transactions a month (20 to 50) and your annual turnover (€20,000 to €100,000); the most expensive plan, Ultra (€37.50), has unlimited bank transactions and is meant for a turnover from €100,000. Grow past one of those limits and you move up a plan. The booxx package costs €19 a month with no cap at all and works in five languages — Dutch, English, Polish, Hungarian and Romanian — right down to the ledger accounts. If you sell hours and read Dutch comfortably, MoneyMonk is the better choice; if you do not read Dutch, you cannot run the core of your administration there yourself. You bring your existing books along here as an audit file (XAF), ledger and open items included.
