Article Summary

Each action taken against an account will have an effect on your company's balance sheet, whether it's a deposit, a withdrawal, or the application of interest or fees. If you have set up a Chart of Accounts, you can link individual actions and transaction types to one of your General Ledger (GL) Accounts.

After linking them to GL Accounts, Mambu will automatically post journal entries on the corresponding GL Account whenever a transaction occurs. You can only link to Detail type accounts. Header accounts will not be selectable, as these are designed to provide a sum total for all of the detail accounts under them rather than record individual transactions. For more information, see Creating Your Chart of Accounts - Chart of Accounts Structure.

This article provides an overview of Mambu's standard behavior for loans and deposit accounts and provides examples based on a simple chart of accounts.

If you need additional support configuring your system, we invite you to reach out to our support team - for more information, see Contacting Support.

Please Note

When adding fees to a product, you can opt to use the product default General Ledger Accounts for Fee Receivable, Fee Income, Fee Losses, and Deferred Fee Income or set these to custom GL accounts. This allows you to have much more granularity in your reporting by, for example, differentiating between manual and automatic fees. For more information, see Fees accounting.

Loan Product Rules under Cash basis Accounting

The following table shows Mambu's behavior after the accounting rules per product have been set:

Transaction TypeDebitCredit
Loan DisbursementPortfolio ControlTransaction Source
Principal Write-Off*Write-Off ExpensePortfolio Control
Principal (Re)paidTransaction SourcePortfolio Control
Interest PaidTransaction SourceInterest Income
Fee PaidTransaction SourceFee Income
Penalty PaidTransaction SourcePenalty Income
Taxes (VAT) PaidTransaction SourceTaxes Payable
Please note

Under cash based accounting rules, as nothing accrues, there are no separate general ledger entries for writing off interest or taxes that would have been payable on the loan account.

After enabling the Cash basis Accounting method, Mambu will display dropdown menus where you can choose the accounts depending on the type (asset, expense or income) in each one of them.

Select corresponding General Ledger Accounts for loan products using cash based accounting

After saving the changes the transactions will start being logged automatically in Accounting following those rules.

Loan Product Rules under Accruals Accounting

In the following table you can see Mambu's internal behaviour when you define the accounting rules in a Loan Product under Accruals Accounting:

Like in the previous method, after enabling the Accruals Accounting method, Mambu will display dropdown menus where you can choose the accounts depending on the type (asset, expense or income) in each one of them.

Select corresponding General Ledger Accounts for loan products using accrual based accounting

For loan product types with accrual accounting you can select for the Interest Accrued Method to be Daily. Every day, when the End of Day Process runs, Mambu will log journal entries in accounting for the total amount of interest that is accrued (and not yet applied) on your active accounts. On the next process execution, Mambu will reverse the previous day's entries and log new ones with the updated accrued amounts.

Interest Accrual Method dropdown with Daily and Monthly options

Click on save and from this point onwards Mambu will log all of your transactions according to these rules.

When adding and configuring fees for your product you can indicate that the product default General Ledger Account for Fee Income should be used for this fee or select any other account. This will allow for greater granularity in reporting.

Just like for Loans, after enabling the accounting in the product, select the account depending on the type (asset, liability, expense or income) in the dropdown menus > save it and from that moment on, the transactions will be automatically logged in Accounting.

Deposit Product Rules under Cash Basis Accounting

For deposits, Mambu will manage the accounting using the rules below. See the sub-sections for additional information regarding interest application/accrual.

Deposit Product Rules under Accruals Accounting

For deposit product types with accrual accounting, the Interest Accrued Methods available are Daily or Monthly. The process is the same as for loan product types, meaning that every day, when the End of Day Process runs, Mambu will log journal entries in accounting for the total amount of interest that is accrued (and not yet applied) on your active accounts. On the next process execution, Mambu will reverse the previous day's entries and log new ones with the updated accrued amounts.

If you allow overdrafts and want to use this option, define all Overdraft-related GL accounts, and journal entries will be posted.

When overdraft interest or fees are applied on the account, accounting entries will be posted. Mambu will credit the Overdraft Interest or Fees Income rule and debit the Overdraft Portfolio Control.
