Enabling SEPA Mandate Payment Instruments

JustOn makes use of Payment Instrument records to hold the SEPA Direct Debit Mandate information for accounts. If there is an active payment instrument set for an account, JustOn uses the following fields of the payment instrument for the SEPA export: IBAN, Direct Debit Mandate Granted and Direct Debit Mandate Reference. If there is no active payment instrument, this information is taken from the invoice or the account.

You can create and update account-specific payment instruments based on the SEPA-related information available on the account using a dedicated process. Once created, the payment instruments are accessible via the corresponding related list on the account detail page.

Enabling SEPA Direct Debit Mandates as payment instruments involves

Configuring SEPA Mandate Reference Counter

JustOn requires the specific invoice counter MandateReferencePaymentInstrument to act as the SEPA mandate reference counter. Once set up, the SEPA mandate reference for the payment instrument is set automatically by the process on creation or update.

  1. In Setup, open Custom Settings.

    In Salesforce Lightning, navigate to Custom Code > Custom Settings.

    In Salesforce Classic, navigate to Develop > Custom Settings.

  2. Click Manage in the row of Counters.

  3. Click New.
  4. Specify the details as necessary.

    • Name: MandateReferencePaymentInstrument
    • Template: Specify the pattern as necessary.


      The resulting mandate string can contain up to 35 characters. The allowed characters include the alphanumeric characters a-z A-Z 0-9, the punctuation and symbol characters +?/-:().,' and the space character.

      Note that there is no support for custom placeholders with SEPA mandate reference counters.

  5. Click Save.

Creating Process for Managing Payment Instruments

Creating or updating SEPA mandate payment instruments requires a process that calls the appropriate Apex class provided by JustOn. When the defined criteria are met, the process can, generally

  • Create a new Payment Instrument record with the IBAN, Direct Debit Mandate Reference and Direct Debit Mandate Granted fields populated, which will be used on SEPA XML export,
  • Deactivate an existing payment instrument and create a new one if a new IBAN value is available,
  • Deactivate all payment instruments if the IBAN value is empty.

If applicable, the process sets the active payment instrument in the Account field Current SEPA Mandate.

The source object for the process depends on the object to be monitored for changes to the SEPA-related information – usually Account or Invoice.


Depending on your use cases, the process setup and the objects to involve will vary.

  1. In Setup, open Process Builder.

    In Salesforce Lightning, navigate to Process Automation > Process Builder.

    In Salesforce Classic, navigate to Create > Workflow & Approvals > Process Builder.

  2. Click New.

  3. Specify a (descriptive) process name.
  4. Set the process to start when A record changes.
  5. Configure the process as required.

    Step Option Description
    Add Object Object The original object whose modifications are to create or deactivate a payment instrument, usually Account or Invoice
    Start the process The type of record change that triggers the process, must be when a record is created or edited
    Add Criteria Criteria for Executing Actions The type of criteria, determines whether to check for specific field values or to evaluate records using a formula
    Set Conditions | Build Formula The use case-specific criteria, either the filter conditions for evaluating field values or the formula
    Add Action Action Type The type of action to be executed, must be Apex
    Apex Class The Apex class to be executed, must be Manage Payment Instrument records for SEPA
    Set Apex Variables Invocable variables for the Apex class
    Account Id specifies the reference to the ID field of the relevant account
    IBAN optionally specifies the reference to the ON_BankAccount field of the account, used to pass a new IBAN value
  6. Click Save.

  7. Click Activate.

Example use case: IBAN of an account is modified

To trigger the process when the IBAN of an account is modified, for example, specify:

Option Value
The process starts when A record changes
Object Account
Start the process when a record is created or edited
Criteria for Executing Actions Conditions are met
Set Conditions [Account].ON_BankAccount__c Is changed True
Action Type Apex
Apex Class Manage Payment Instrument records for SEPA
Set Apex Variables Account Id Field Reference [Account].Id
IBAN Field Reference [Account].ON_BankAccount__c

This triggers JustOn to execute the process when the ON_BankAccount field of an account modified: It deactivates the existing payment instrument and creates a new one with the new IBAN.
