How can I analyze the pattern of merchants account transactions in a bank and identify the merchants that are becoming inactive?

Which methods should I use to solve this problem?

If you don't have a lot of data, I suggest you using time series models, such as ARMA, ARIMA, etc.

If you have enough data, I suggest you use LSTMs.

In both cases, I would aggregate data to some periods, say amount of transactions for month, and use them (and data from all previous months) to predict transactions in the next month.
