NACH Debit mandates can have frequencies ranging from intra-day to yearly, and also ad hoc.
Payments can be charged on a mandate according to the mandate's frequency. Mandates can have the following frequencies, and payments can be taken on the periodic anniversary of the first collection date:
- Intra-day (INDA): Multiple payments can be taken every day. eMandate only.
- Daily (DAIL): One payment can be taken every day. eMandate only.
- Weekly (WEEK): One payment can be taken every week. eMandate only.
- Monthly (MNTH): One payment can be taken every month. All mandate variants.
- Bi-monthly (BIMN): One payment can be taken every two months. eMandate only.
- Quarterly (QURT): One payment can be taken every three months. All mandate variants.
- Half yearly (MIAN): One payment can be taken every six months. All mandate variants.
- Yearly (YEAR): One payment can be taken every year. All mandate variants.
- Ad hoc (ADHO): Multiple payments can be taken every day. All mandate variants. This frequency is also known as "As and When Presented". NPCI imposes certain restrictions on usage of this frequency.
LotusPay does not impose minimum frequency interval restrictions on merchants scheduling payments on independent mandates (a mandate which is not linked to a LotusPay subscription). NPCI itself does not impose any such restrictions. However, each destination bank has its own policy on handling payments that fall outside of these intervals.
For example, suppose a customer has authorised a mandate which has a frequency of 'monthly'. Legally, the merchant should only charge this mandate once per month. Technically, however, the merchant can submit charge requests more frequently e.g. daily. Doing so will cause the request to fail (unless it is a resubmitted charge request for an earlier failed payment). This is because the customer's bank will see that the charge request is breaching the frequency condition as authorised by the customer in the mandate: the merchant is trying to take payments more frequently than the customer has authorised.
Therefore, with independent mandates, the onus is on the merchant to ensure that they are honouring the frequency condition of the customer's mandate.
If you need to charge the customer at irregular intervals, you should ask the customer to authorise a frequency of 'Ad hoc'.
If you do not want to handle the complexity of scheduling payments, you can benefit from using LotusPay's subscription and plan logic instead.
