When you successfully complete the automated process to connect your Bank, you can make a transfer almost immediately (although occasionally the auto-linking process can take up to 1-2 business days).  If you must enter your bank routing number and bank account number, two micro-deposit transactions will be sent to you to verify.  The micro-deposit transactions will take 2-3 business days to be received into your bank account.  Once you see them, just confirm both amounts back in your Evati account by selecting Settings and then Banks.
