Defining financial services
In this section, we'll guide you through the process of identifying the financial services your system will provide and determine the specific requirements for each service.
1. Identify the financial services your system will provide
Start by defining the financial products and services your system will offer, such as checking accounts, savings accounts, loans, and credit cards.
2. Determine the specific requirements for each service
Once you have identified the financial services your system will provide, you need to determine the specific requirements for each service. This includes account types, transaction types, and fees associated with each service.
A hypothetical neobank, for example, might provide the following services:
Checking Accounts: These accounts will support deposits, withdrawals, and direct transfers between customers. You'll need to create a chart of accounts that includes customer checking accounts, as well as internal company accounts for tracking revenue and expenses.
Savings Accounts: Similar to checking accounts, these accounts will also support deposits, withdrawals, and transfers. You may also want to include interest calculations and fees for certain actions, such as withdrawing funds before a specified period.
Loans: For loan products, you'll need to track the principal balance, interest rate, and repayment schedule. You'll also need to create accounts to represent loan disbursements and repayments.
With Twisp, you can create a flexible chart of accounts to model the economic activities required for your specific use case. Additionally, Twisp enables you to define transaction codes to represent different types of financial activities, such as deposits, withdrawals, transfers, and fees. This will help you design a robust and adaptable system to support the financial services you offer.
In the next section, we will delve into designing accounts and transactions to support these financial services using Twisp's accounting core features.
Designing accounts and transactions
In this section, we will walk you through the steps to design and create a chart of accounts and transaction codes for different types of financial activities. This process is crucial for organizing your financial data and establishing rules for posting transactions to accounts.
1. Create a chart of accounts
A chart of accounts models all the economic activity that your financial system will provide. It is the basis for creating balance sheets, P&L reports, and for understanding the balances for the customer and business entities your system services.
To create a chart of accounts, you need to:
- Identify the different account types you need to support your financial services. These can include assets, liabilities, income, and expenses.
- Create accounts for each type and purpose. For example, you might have accounts for customer wallets, settlement accounts for ACH transactions, and accounts for revenue.
- Organize accounts into sets using the AccountSet type. This will help you manage hierarchical tree structures and roll up balances across multiple accounts.
2. Define transaction codes
Transaction codes (tran codes) represent different types of financial activity, such as deposits, withdrawals, transfers, and fees. They encode the basic patterns for a type of transaction as a predictable and repeatable formula.
To define transaction codes, you need to:
- Determine the type of transaction (e.g., ACH transfer, credit card purchase, foreign exchange).
- Identify the accounts involved in the transaction. Determine where the money is coming from and where it is going, including any additional accounts that need to be debited or credited.
- Establish the number of entries that should be written to the ledger for each transaction, as well as which entries go on the debit side and which on the credit side.
- Specify whether these entries reflect a settled amount, or if they are still pending a final settlement.
3. Establish rules for posting transactions
Once you have designed your accounts and transaction codes, you need to establish rules for posting transactions to accounts based on the transaction codes.
This process involves:
- Creating a framework for how transactions are recorded in the ledger. In Twisp, every transaction writes two or more entries to the ledger in standard double-entry accounting practice.
- Ensuring that your transaction codes and accounts align with the double-entry accounting principles. For every transaction, there should be at least two entries that balance out across debits and credits.
- Implementing the rules in your financial system to automatically post transactions to the appropriate accounts based on the transaction codes.
By following these steps, you can successfully design accounts and transactions to support your financial system built on the Twisp accounting core.
Security and compliance

1. Test with sample data
Begin by populating your Twisp ledger with sample data that mimics the financial activity and transactions you expect to see in your final product.
Use the GraphQL API to create accounts, define transaction codes, and post transactions that cover a variety of use cases.
For example, in a hypothetical neobank you would create sample customer accounts for checking, savings, and loans, then post transactions such as deposits, withdrawals, transfers, and fees. By working with realistic sample data, you can identify potential issues and areas for improvement early in the development process.
2. Test various use cases
Ensure that your financial system can handle a wide range of scenarios by testing multiple use cases.
For instance, test the ledger's handling of edge cases, such as large transactions, insufficient funds, and high transaction volumes. Additionally, test the system's response to invalid or incorrect data, such as incomplete transaction details or incorrect account numbers.
This could involve simulating a large transfer between customer accounts, an attempt to withdraw more funds than a customer has available, or processing a high number of transactions within a short period.
3. Validate calculations and balances
As part of the testing process, it is crucial to verify that the balances reflect the intent of your account structures. To do this, compare the results produced by your financial system with manually calculated or known results.
You might check that the balances for each sample customer account are updated correctly after each transaction and that any applicable fees are calculated and applied accurately.
