It's up to you whether you want Mettle to be your main business account or not. Some of our users have set up Mettle to handle all of their business, while others use it as a secondary account.
Because of the way Mettle is built, the more you use it, the more useful our features will become for you. By creating invoices, setting up bills & sending and receiving payments from the app, Mettle will be able to provide you with a more precise view of your future cashflow.
Remember there are certain limitations in the Mette account at this stage, such as £50,000 maximum balance or £10,000 maximum payment out (payments in are only limited by the maximum balanced allowed). If you routinely exceed these, we'd recommend using another account simultaneously.
