Our API offers access to standard and electronic mandates/DDIs (E-Mandates).
If you require your payers to sign paper mandates then the standard mandate/DDI approach would be appropriate. Please contact a member of our Customer Services team for more details.
For more information on E-Mandates please check out the various E-Mandate implementation options.
In the Bacs scheme, new signed DDIs must be lodged and validated with the payers’ banks before collections may be made against them. Bacs offer an automated electronic process to register/lodge these DDIs called the Automated Direct Debit Instruction Service (AUDDIS). When your payers sign a DDI, Nuapay will automatically include it in an AUDDIS submission. AUDDIS submissions are generated daily from Nuapay (Monday to Friday).
This is the lifecycle of a DDI:
- A DDI is created in
- The payer signs the DDI and Nuapay moves its status to
READY FOR EXPORT.
- Once per day, Nuapay picks up all
READY FOR EXPORTDDIs and includes them in an AUDDIS submission file, which is passed to Bacs; at this point the DDI status is updated to
- Bacs operates on a 3- to 4-business day cycle (see below) so when the scheme receives the AUDDIS file from Nuapay it processes all the DDIs contained in it and lodges the instructions with the various payers’ banks.
- Where there are issues with a submission (e.g. the account provided does not allow Direct Debit payments to be taken, for example), Bacs will inform Nuapay via an AUDDIS response file and that DDI will be automatically updated to
REJECTED. You may want to configure a Webhook to be automatically notified of this: see details on the Mandate Reject Event page.
- Where there is no issue, the DDI is deemed to be successfully lodged and its status is updated to
ACTIVE. Once a DDI is in Active status, Direct Debit payments may be made against it.

AUDDIS Processing Cycle
|Day1||Day2||Day 3||Day 4|
|Nuapay transmits the AUDDIS file to Bacs||Bacs passes valid DDIs to the paying banks||Valid DDIs are lodged against payers’ accounts; details of invalid DDIs are passed to Nuapay||(Similar to Day 3) Valid DDIs are lodged, invalid DDIs are passed back to Nuapay and their status is updated to
Mandate Lodgement in the B2B Scheme
After signing a B2B Mandate, your payer must inform his/her bank of the mandate setup. Depending on the bank, it may be possible to do this online but every bank will have its own method to allows its customers to lodge their B2B mandates. (Unlike in the Bacs scheme, there is no automated process for this).
Before they can process a B2B Direct Debit, your payer’s bank must:
- Confirm that the mandate details provided to them are correct and have been confirmed and authorised by the payer.
- Check the first and the subsequent Collections against the stored Mandate data.
- Ensure that their clients are aware that the bank must be informed of any amendments or cancellations of the mandate.
Working with paper-based mandates can be problematic:
- You need to use standard post.
- Your payers may be slow to return the signed mandate.
- Users may make an error when writing their account details.
- In some cases the signature may be unreadbale or the payer may have incorrectly completed the form.
- Assuming the mandate/DDI is returned and has been completed correctly, you then need to store the paper mandates and ensure that they can be retrieved later if required.
Electronic mandates remove all these pain points:
- Users sign the mandates online.
- Account details are validated in real time (so your payers cannot provide you with an invalid account number).
- The mandate is set to ACTIVE status immediately (for the SEPA CORE scheme) so you can begin to take payments right away: no waiting for signed paper mandates to arrive. 1. (Note that for BACS, DDIs are subject to the lodgement and collection cycle so mandates do not go into ACTIVE status immediately (see the previous section)).
- Your users receive emails to confirm activation of their mandates so again, less admin work for you!
- Mandate/DDI details can be easily retrieved at any time via the List Mandates service.
