I run a boutique design agency and every now and then I end up with surplus cash after big invoices clear. Truth is, it sits in our current account earning zero interest until I remember to move it. I want to adopt some best practices for funneling extra funds into an easy-access savings account without losing the agility to cover sudden client expenses. Should I set thresholds for automatic transfers, or use certain tools to switch funds back and forth? Curious what routines seasoned business owners recommend.
