Due to unforeseen roadblocks with our banking partner, we are unable to process debit card investments. Luckily, it is simple to adjust your payment method, and it's likely that you can use the same account as your original investment. All that's changing is that instead of processing your investment via debit, we'll process it using ACH.

Bear in mind that if you have already made an investment via debit card that has closed, and want to continue making investments, we will require bank linkage for future transactions and for repayments.

Switching from debit to ACH

You should have received an automated email outlining the steps needed to switch out your payment method and re-initiate your investment. This email will include links that go right to each step, but you can use this article as a guide as well.

Step 1: Link a bank account

It is secure and simple to link a bank account on Mainvest. There are 3 options for linking an account, and all three can be found at You should see your existing payment method here. First, choose "Add a Payment Method"

Then, you can proceed with one of three options to link your bank account.

Linking via Plaid

Plaid is the industry leader in bank linkage, trusted by Venmo, Acorns, and Chime. To link via Plaid, all you have to is follow the on-screen prompts to log into your account through online banking. From there, choose your checking account and you'll be all set to invest.

Linking via voided check

If Plaid doesn't have a connection with your bank, you can upload a picture of a voided check to proceed with investing. Ensure that the routing and account number are clear, that the name on the check matches the name on your account, and that it's a photo or scan of a physical check.

Linking via account and routing number

If neither of the above options work for your bank, you can enter your account and routing number where prompted. From there, we will send 2 small deposits of just a few cents to your bank account within 1-3 business days. Once you have those deposits, head back to to enter them in. This will verify your account and you'll be able to start investing.

Step 2: Re-initiating your investment

Once you've fully linked a bank account, you'll be able to re-initiate your investment. Bear in mind that due to the verification process, this process may not be instantaneous if you've chosen to link via voided check or microdeposits.

First, navigate to your portfolio. Find the business with the failed investment and click into it.

Here, you should see the details of your investment, and it will say "Failed." If you have successfully linked your bank account, click "Reinitiate." It's ok to come back to this step later, or to contact support for assistance, if you're still in the process of linking your bank account.

From there, you will confirm the new account with which you're reinitiating the investment. When you see the final confirmation screen, you're all set!

As always, if you have any questions, don't hesitate to reach out to Mainvest support.
