Add security and opportunity to idle funds with a WSB Savings Account. A piggy bank or cash stash might work for your own finances, but when business dealings are at stake, a more traditional approach is probably a good idea.
All deposits are insured in full, even beyond FDIC limits. And competitive interest is paid on the entire balance. Even avoid the low $3 monthly service fee by maintaining a $50 daily balance. Save for a rainy day or something specific with this streamlined account.
