eMandates can have an amount of up to Rs 1 lakh, and the amount can be either a fixed amount or a maximum amount.
NACH Debit mandates require an amount. For eMandates, this amount can be up to Rs 1,00,000 (one hundred thousand). NPCI will likely revise this limit upwards in 2020 subject to RBI approval.
A mandate must have a fixed amount or a maximum amount (one or the other, but not both).
Fixed amount: The payment can be of this amount only, nothing more and nothing less.
Maximum amount: The payment can be any amount up to and including this maximum amount, nothing more.
- Subscriptions always use 'Maximum amount'. The LotusPay subscription logic allows you to vary the charge amount to be anything up to and including this maximum amount. For example, suppose you start a customer's subscription with an amount of Rs 1,000:
- Increasing a subscription amount: You can reduce the charge amount to Rs 900 without asking the customer for authorisation. If your customer is not willing to retain a mandate which has a higher amount than the subscription amount, you can ask the customer for authorisation or cancel the subscription and create a new one with the lesser amount.
- Decreasing a subscription amount: If you need to increase the amount to anything above Rs 1,000, the customer must authorise an amendment to the mandate.
- Independent mandates (those which are not linked to subscriptions) always ask you to choose between 'Fixed amount' and 'Maximum amount' during creation.
- If your subscription billing charge will vary from period to period, you should use 'Maximum amount'.
- Increasing or decreasing the mandate amount: The amount can be amended by asking the customer for authorisation to amend.
