The verdict
If you run an agency, consultancy or IT services firm with several people, projects and budgets to watch, pick Productive. If you are a freelancer or sole trader who wants a separate account and a simple way to send an invoice, pick Revolut Pro.
They are not alternatives for most people. A small agency could use Productive to run delivery and invoicing and hold its money in any business bank account. A solo freelancer gets little from Productive, because its value comes from time, budget and resourcing across a team. Revolut Pro would not give a team any of that, and it is not a bookkeeping tool either.
