Customers of financial institutions often find it difficult to keep track of their account activities. These customers may be unaware of the details of their transactions, account balances, and account policies and may miss potential opportunities and susceptibilities associated with their accounts. For example, a customer may not realize that they are eligible for an upgraded service because they are unfamiliar with their bank's policies and products. Moreover, financial institutions usually have large volumes of data to organize and maintain, and may not have the resources to easily analyze the data and keep customers informed. Such financial institutions may miss opportunities for growth by failing to inform their customers of possible issues, offers, and product updates at the most opportune times. For example, a financial institution may fail to timely notify a customer of an investment offer and may miss an opportunity to strengthen their relationship with the customer as a consequence.
The embodiments provided herein are directed to a system for producing and maintaining account-related triggers. The system includes a computer apparatus including a processor and a memory; and a trigger software module stored in the memory, comprising executable instructions that when executed by the processor cause the processor to: receive account data associated with one or more accounts; store the account data in a storage device; determine patterns of account activity based on the account data; identify parameters associated with the patterns of account activity, the parameters comprising at least one of a transaction channel, transaction category, threshold amount, business name, stability indicator, and violation frequency; and form triggers based on the patterns of account activity and parameters.
In some embodiments, a system for monitoring one or more accounts of a financial institution is provided. The system includes a computer apparatus including a processor and a memory and a financial ratio software module stored in the memory. The module includes executable instructions that when executed by the processor causes the processor to receive account data associated with the one or more accounts, store the account data in a storage device, and execute triggers to monitor financial account ratios.
The present embodiments are further described in the detailed description which follows in reference to the noted plurality of drawings by way of non-limiting examples of embodiments of the present embodiments in which like reference numerals represent similar parts throughout the several views of the drawings and wherein:
The embodiments presented herein are directed to systems and methods for enhancing and maintaining customer relationships with an organization by the creation, institution, and management of account related triggers. In some embodiments, a system that supports ideation, sizing, design, production, and maintenance of triggers is provided. The system develops effective communication routines to aid in trigger delivery. Other embodiments are directed to monitoring data quality by checking historical volume and calculating high and low control limits to determine whether current volumes are in control. Such data quality monitoring minimizes false positives.
Other embodiments are directed to retaining users in their existing relationships with a financial institution. Based on account data, comparisons of past and current transactional activity are made and a slowdown in account usage is determined. In response to the determination, notifications are presented to the user to increase customer satisfaction and retain the customer relationship. Financial institutions find this approach desirable because it is more cost effective and profitable to retain existing relationships than it is to acquire new customers.
Still other embodiments are directed to increasing transactional depth or account breadth. Incoming and outbound transactions are evaluated over a period of time to identify accounts that are close to a certain threshold. Users are notified of their account status and prompted to increase account activity in order to gain extra benefits. In this way, financial institutions are able to understand their customer's needs and cross sell products. In further embodiments, the relationship with the user is enhanced by timely identifying outside transactions through account review. For example, withdrawals, opening new accounts with a competitor, or making competitor payments are identified and reviewed to avoid losing the user to a competitor.
Further embodiments focus on providing new products to a user by identifying inbound and outbound transactions that signify a change in account activity or relate to a particular type of transaction. Triggers related to payment types and increases in deposit amounts are identified to enable a financial institution to cross sell products to users.
In other embodiments, account information is reviewed to identify accounts that have unavailable funds and fixed costs and users are presented policy information. In this way, users are educated so that they can avoid fixed costs and are made aware of available options so that they can make informed decisions.

The banking system application 390 includes a trigger software module for performing the steps of methods and systems 500-1100.
As used herein, a “communication interface” generally includes a modem, server, transceiver, and/or other device for communicating with other devices on a network, and/or a user interface for communicating with one or more customers. Referring again to
The network communication interface 410 is a communication interface having one or more communication devices configured to communicate with one or more other devices on the network 150. The processing device 420 is configured to use the network communication interface 410 to receive information from and/or provide information and commands to the user's computing device 200, the third party system 170, the trigger repository 400, the banking system 300 and/or other devices via the network 150. In some embodiments, the processing device 420 also uses the network communication interface 410 to access other devices on the network 150, such as one or more web servers of one or more third-party data providers. In some embodiments, one or more of the devices described herein may be operated by a second entity so that the third-party controls the various functions involving the trigger repository 400. For example, in one embodiment of the invention, although the banking system 300 is operated by a first entity (e.g., a financial institution), a second entity operates the trigger repository 400 that stores the trigger details for the customer's financial institution accounts and other information about users.
As described above, the processing device 420 is configured to use the network communication interface 410 to gather data from the various data sources. The processing device 420 stores the data that it receives in the memory device 450. In this regard, in one embodiment of the invention, the memory device 450 includes datastores that include, for example: (1) triggers associated with a user's financial institution account numbers and routing information, (2) information about sending and receiving users' mobile device numbers, email addresses, or other contact information, which may have been received from the banking system 300, and (3) online data such as browser cookies associated with the user's computing device 200.
Turning now to the production of triggers, in some embodiments, trigger ideas are formulated and undergo a preliminary review. The ideas may be formulated internally, such as by a team of analysts of a financial institution, or the ideas may be formulated externally by segment, channel, and marketing partners of a financial institution. The ideas are prioritized based on an opportunity analysis. For example, transaction channels, transaction categories, business names, amount thresholds, stability, and violation frequencies are selected to determine and quantify opportunities that can be generated from the trigger ideas. These opportunities, such as customer retention and policy education, may be analyzed in view of preferred, retail, and small business demographics. Based on the opportunity review, triggers are developed through rigorous testing. For example, tests may be conducted on transactions associated with a specific account or user. Further, triggers that are similar in scope and that overlap over the same time period may be monitored to further develop the trigger. The results of the testing may then be reviewed to finalize the triggers. In some embodiments, the triggers are modified for automation. For example, the code for automating the triggers may be embellished and specific parameters provided. In further embodiments, the automated triggers are monitored. For example, content and process quality trigger checks can be run on a daily, weekly, bi-weekly, and/or monthly basis.
As shown in
In block 504, patterns of account activity are determined based on the account data. The account activity, in some embodiments, is specifically linked to a transaction category, transaction type, transaction amount, or transaction channel. For example, algorithms may be used to detect upward or downward trends in the number of transactions, the amount of transactions, the occurrence of account costs, or other account activity over a period of time. Deposit amounts for a particular account, for example, may increase during the month of April for several years in a row and provide an indication that the account user has received a tax refund.
In block 506, parameters associated with the patterns are identified, where the parameters include transaction channels, transaction categories, amount thresholds, business names, stability, and violation frequencies. The parameters are identified, in some embodiments, by using algorithms, keywords, Boolean, transaction channel codes, transaction amount calculations, and threshold amounts to search the account data related to the patterns of account activity. The keywords include business names, merchant names, third party financial institution names, web addresses, transaction dates, transaction amounts, user identification, account identification, and the like.
Transaction channels include transaction processes such as electronic funds transfers, automatic deposits and withdrawals, ATM withdrawals and deposits, point-of-sale (POS) purchases, and the like. For example, triggers directed to deposit transactions may include transaction channel parameters such as teller deposits, ATM deposits, ACH deposits, internal transfers, automatic transfers, and pay roll transfers.
Transaction categories include transactions that are grouped according to a desired outcome or purpose. Exemplary transaction categories include user retention, increasing a user's transactional depth or account breadth, timely identification of outside transactions, new products, risk mitigation, policy education, and the like.
The amount thresholds include predetermined amounts associated with one or more transactions such as minimum and/or maximum percent, total, average, or median limits for quantities or values associated with one or more transactions. For example, some parameters may require that all purchases be over a minimum $100 limit and/or under a $10,000 limit. The stability parameters provide an indication of transactions that perform consistently over time, or an indication of transactions that have been adjusted to remove variations in activity over time. For example, the stability parameters may include a range of percentages, ratios, transaction amounts, and frequencies that fall within specific tolerances and that are linked to specific transactions that are tracked over time. Parameters of violation frequencies indicate the frequency of outliers, unexpected events, and negative results in account activity. For example, if the number of ATM withdrawals for a particular account has gradually decreased from six per month to one per month over the last seven months, seven ATM withdrawals on the same day of the current month would indicate a reversal in the trend and would be a violation of the trigger. The violation frequency can indicate an isolated occurrence which can be deleted or ignored from the data, or it can indicate a negative trend. Based on the violation frequency, the parameters of the triggers can be adjusted accordingly.
In block 508, triggers are formed based on the patterns of account activity and the parameters. In some embodiments, the patterns of account activity and the parameters are used to define the triggers. For example, a trigger may be defined by the total monthly number of ATM deposits that occur over a three month period. Further, the patterns of account activity provide the expected trend for transactions defined by the parameters. In the previous example, the trigger may be further defined by requiring that the total monthly number of ATM deposits decrease over the three month period. The patterns of account activity and parameters selected for each trigger may be based on the objective of the trigger. Triggers directed to cross selling investment products to user, for example, may include a pattern of increasing direct deposits in a saving account over a two week period. The triggers, and the patterns and parameters that define the triggers, may take on any number of variations. Specific exemplary triggers are described in more detail below with reference to
The method 500 is further illustrated in
In block 512, one or more of the similar triggers are evaluated over the same period of time. The evaluation of the similar triggers over the same time periods strengthens the trigger data such that any potential flaws, improvements, or strengths in the data are highlighted. In one example, electronic fund transfers associated with multiple accounts are monitored every day over the same six month period. In this way, the number of times the trigger should be run in a week or month, the days of the week for running the trigger, and any discrepancies in the data that occur during particular days of the week, weeks of the month, and months of the year are determined. In some embodiments, a first group of similar triggers is compared to a second group of similar triggers. For example, a group of similar outbound transaction triggers may be compared to a group of similar inbound transaction triggers. In another example, automatic deposits that occur on Mondays may be compared to automatic deposits that occur on Fridays.
In block 514, the parameters associated with the similar triggers are modified in response to the evaluation of the one or more of the similar triggers over the same period of time. One or more of the parameters for a particular trigger can be added or removed and/or the terms of the parameters can be adjusted. Holidays and weekends, for example, may cause discrepancies in the preliminary trigger data and may be taken into account when defining the trigger. Even after the triggers are preliminarily established, the triggers may be continuously monitored on a regular basis as discussed in more detail below with regard to
In block 516, the triggers are categorized based at least on one of a desired objective, a type of transaction, a type of account, an amount threshold, and/or a period of time. In some embodiments, a first group of similar triggers and a different second group of similar triggers are categorized based on the desired objective. For example, ATM deposits may be categorized with payments for education if the purpose of the triggers is to offer the user a loan with a lower interest rate. The triggers categorized according to the desired objective are further categorized according to the type of transaction, the type of account, the amount threshold, and the period of time. In the example above, the ATM deposits used as triggers for the purpose of loan offers may be further categorized according to the amounts of the deposits. In block 518, the categorized triggers are monitored on a period basis, as discussed in further detail below with regard to
Referring now to
In block 602 of
In block 606, triggers associated with the one or more periods of time are identified based on at least one of a transaction, a transaction amount, a type of transaction, and a type of account. In some embodiments, each set of triggers corresponding to transactions of a certain amount, and/or type are identified first and then the triggers are segregated into time periods. The triggers may be further identified based on a category corresponding to a desired objective. In some embodiments, the triggers are identified based on transactions that occur during the one or more periods of time. For example, a trigger may include all inbound transactions that have values that are greater than a threshold amount and that occur during the month of July.
In block 608, a total transaction count for each of the triggers is calculated. The transaction counts include value amounts for certain transactions associated with one or more accounts or the total number of certain transaction associated with the one or more accounts. In some embodiments, the transaction count is the total number of transactions that occur during the one or more period of time and that are associated with a particular trigger.
Exemplary graphical charts of total counts for a tax refund trigger are illustrated in
In block 610, control limits based on the transaction count for each of the triggers is determined. The control limits are calculated based on trimmed mean and standard deviation. Trimmed mean is calculated by removing a certain percent from the lowest percent of values and an equal certain percent from the highest percent of values in a given data series before calculating the mean. In calculating the trimmed mean, some of the lower numbers of the transaction count and some of the higher numbers of the transaction count are removed before the mean is calculated. For example, tax refund transactions that occur on a Friday and that have a value that is a certain percent higher or lower than the median for all tax refunds that occur on the same Friday are deleted before the mean is calculated.
An exemplary table illustrating the transaction count and control limits is shown in
In block 618, the outliers are tagged. The outliers may be tagged as “outlier” as illustrated in the exemplary table of
In block 620, the cause of the outliers is determined. Periods of time around holidays, cyclic considerations such as tax season, days of the week, weeks of the month, certain historical trends, data obtained from the user, and external data can indicate the cause for the outliers. For example, historical trends may indicate that the number of mortgage payments is higher at the end of the month than at the beginning of the month and the number of ATM withdrawals may be higher on Fridays than it is on Tuesdays. As another example, triggers that include transactions having a specific threshold amount of $10 or greater may have a higher number of transactions during a particular period because a greater number of low end transactions (e.g., transaction of $10 to $12) occur during that period. Based on the cause of the skewed data, appropriate action can be taken. For example, the threshold amount or some other parameter associated with the trigger may be modified or certain triggers associated with a particular day of the week or other period may be tagged as normal even though these certain triggers would appear to be abnormal. Taking the $10 or greater trigger example described above, for example, the threshold amount for that trigger may be increased during the particular period or marked as normal. If the cause of the outliers is not easily explained or if the cause is unexpected, then further investigation may be required.
Although the triggers described herein generally include financial transactions associated with one or more accounts, such as the triggers illustrated in
In block 702, account data associated with one or more accounts are received and the account data is stored in a storage device (e.g., the user account data repository 380 or the trigger repository 400). In block 704, triggers are executed to monitor account ratios. The triggers may monitor one or more transactions that occur during a defined period of time, type of transaction, etc. In some embodiments, the defined period of time may be one week, one month, three months, one year, etc. The trigger groups may be further identified based on an amount, a transaction channel, an account type, and the like.
Exemplary trigger relating to the system and method 700 are illustrated in Trigger Table 1 of
The next exemplary trigger noted in table is “INFLOW2.” The INFLOW2 trigger may serve to monitor the ratio of income from competitor institutions to total inflow. This ratio may be beneficial in determining the reliance on competitors. The “OUTFLOW” trigger may examine the ratio of payments of necessities vs. discretionary payments. The “OVERALL” trigger is a ratio of total income to total outflow. Again, greater than 1 signifies savings, whereas less than 1 signifies spending.
In block 706, the ratio data is analyzed and a determination is made as to what type of action (if any) to take. As noted above, a sudden shift in ratio data may be indicative of a one-time event such as an annual bonus or sudden unemployment. An algorithm may be utilized to select customers based on the ratios or changes in ratios for cross-selling opportunities to market additional services.
