A new checking customer gives your bank high marks for account opening. Six months later, the account still has its opening deposit and little activity. Another customer gives the experience the same score, then sets up direct deposit and opens a savings account. Both responses look the same on a CX dashboard. The account records tell two different stories.
That’s a useful starting point for a bank or credit union trying to decide where to invest in customer experience. Pairing survey responses with account activity can show which experiences are associated with deeper relationships and where a change might be worth testing.
Start with a question about customer behavior
Suppose your team wants more new checking customers to use the account for everyday banking. Ask whether customers who report an easier onboarding experience are more likely to fund their accounts within 30 days or set up recurring direct deposit within 90 days. At six months, look at balances, whether the checking account is still active, and whether the household has added another product.
Choose the CX measure that fits the question. A satisfaction question about account setup can tell you how customers felt about that step. Net Promoter Score (NPS) and the Customer Relationship Index (CRI) can give you a broader view of the relationship. If the goal is to understand what happens after account opening, use feedback collected near that experience and look at activity that follows it. A survey completed after a customer has already moved their payroll or opened a second account reflects a different point in the relationship.
Compare customers who started in similar circumstances
A higher average balance among customers who gave onboarding top marks can be worth investigating. Before treating it as evidence for an investment, look at who’s in each group. Did one group include more existing customers who already kept most of their deposits at the institution? Did more of them open accounts during a promotional rate offer? Were they more likely to open in a branch, where someone could walk them through setup?
Start with a comparison your team can explain. Look at first-time checking customers who opened through the same channel, during the same period, under the same offer. Use the same follow-up windows for everyone and check whether survey respondents differ from the broader group of new customers on measures you can observe. Define the outcomes, too. Money moved from an existing savings account into checking increases that checking balance, while total deposits at the institution stay flat. Similarly, a household that opens a second product and closes it shortly afterward looks different from one that still uses both products six months later.
Use the findings to choose what to test
Imagine the clearest difference shows up in direct deposit. Customers who say they understood the next steps after opening are more likely to have recurring payroll deposits within 90 days. Their comments mention knowing where to find their routing and account numbers. That gives the team a specific change to try, such as adding direct deposit instructions to the welcome email or walking customers through the first step before they leave the branch.
Where feasible, assign eligible customers at random to receive either the updated onboarding or the current version. Track direct deposit setup first, then check whether any improvement carries through to balances, active accounts, or products per household over the next six months. A rise in direct deposit setup is useful on its own. If the investment was meant to grow deposits, leadership will also want to see whether households brought in new money and kept it there.
That gives leadership something concrete to weigh against the cost of the change. A small improvement to a welcome email has a different cost than a new onboarding platform. Knowing which behaviors changed, how much they changed, and whether the effect lasted helps the institution decide how much to spend and where.
