How does the billing engine works?

Billing is divided into 2 types recurring and prepaid (monthly/daily).

Recurring billing is the best solution for ISP charging the customer a fixed price on a recurring basis typically at the beginning of the billing cycle. Recurring type of billing is set by default in Splynx global configuration.

Recurring Invoices can be issued every month in advance (Prepay) or in Postpay Mode. One month in advance means, for example, that 1st of May Splynx will generate invoices for 1-31 of May. Postpay means that Splynx generates invoices on 1st of May for the period of 1-30 of April. Also, you can manually generate the invoices before the billing date.

Prepaid billing is used when ISP charges the customer in advance and provide him access for a certain period of time. When the balance of the customer reaches the set limit, he is disconnected. Splynx calculates the daily rate of the plan and charges user every day.

What billing types are supported?

Splynx’s billing engine allows you to set up recurring or prepaid type of billing.
