Analyzing Client Transactions and Payments using SQL
It is common knowledge that information is power. Organizations across industries are constantly seeking ways to harness the wealth of data at their disposal to make informed decisions, streamline operations, and improve overall efficiency.
I delved deep into this dataset, providing valuable insights into client transactions and payments. In this article, I will take you through this fascinating journey of data exploration and explain the crucial need for such analysis using SQL.
The dataset includes information on invoices, clients, and payments. It allows us to track transactions, payment methods, and the financial health of our clients.
Client Invoices
1. We create a CTE named “client_invoice” that selects customer information from the “invoice” table who have made payments. We achieve this by joining the “clients” and “invoice” tables on the common “client_id” column.
INSIGHT:
- Identical customers have made purchases but have yet to complete payments on different orders.
Unpaid Invoices
2. This retrieves specific columns from two tables, “invoices” and “clients,” and filters the results to include only those where the “payment_total” in the “invoices” table is equal to 0. It allows you to identify clients who have not made any payments for their invoices.
INSIGHT:
- Vinte is listed most having more unpaid balance than any customer.
Payment Methods Analysis
3. This SQL query combines data from three tables, “invoices,” “clients,” and “payments,” to create a Common Table Expression (CTE) named “client_record.” It then selects rows from this CTE where the “payment_total” is greater than 1.
Also, this query determines the client’s choice of payment “payment_method”
INSIGHT:
- It provides a way to analyze clients who have made significant payments and is useful for identifying such clients within the dataset. These clients have also used varying payment methods
CONCLUSION
Client Invoices: One of the aims of this analysis is to understand the client invoices, who are paying on time, and who might need a gentle nudge. It’s an in-depth insight into payment patterns and client behaviors. While some clients have started payments, they have multiple invoices.
Unpaid Invoices: From the analysis, unpaid invoices are identified and it is important to work on strategies to recover those funds. A closer look at Vinte’s financials who appear to have the most unpaid invoices, examining their total issued invoices and payments. It’s crucial to understand the financial health of our clients.
Payment Methods Analysis: Combining data from three tables, gives a comprehensive view of payment methods and amounts. Understanding the preferred payment methods of our clients can help us tailor our services and make payment processes smoother and more convenient for them.
