Custom prepaid billing and one-time services

Customer orientation is the key objective for Splynx company as we continuously adding features that our customers request. Starting from v.2.3 our billing engine becomes more powerful and flexible for any ISP. 

It is possible to charge customers daily, monthly or by any set period with the custom prepaid plans. Let’s imagine that we need to provide Internet access only for 7 days:

The desired custom period can be set to new service while creation or set for any existing service.

The customer with ‘Weekly Plan’ will be blocked in 7 days, in case a new payment was not done.

It is also possible to set the custom charged period for every customer from billing settings.

One more feature that makes life easier is One-Time services. Every provider has Installation, Maintenance or other one time charges needed to be added to the final invoice.

The service can be added directly from Invoices or Transaction tabs which makes it more convenient for your billing managers and administrators.

  • Customer > Transactions > Add Transaction >  Select the needed plan

  • Customer>Invoices>Add one-time invoice> Click on a flag icon to apply the one-time service.

Splynx also has a powerful recurring billing engine that is fully customizable to suit the needs of every provider. Check this out here.

Recurring Billing Engine

Splynx billing engine was tailored to specific telecom’s needs to bring the billing management to the next level and automate this routine process.

Recurring billing is the best solution for ISP charging customers a fixed price typically at the beginning of the billing cycle.

Recurring Invoices can be issued every month in advance (Prepay Mode) or in Postpay Mode. One month in advance means, for example, that 1st of April Splynx will generate invoices for 1-3 of April. Postpay means that Splynx generates invoices on the 1st of April for the period of 1-30 of March.

Each ISP can customize recurring billing settings for every single customer:

  • Payment period – the period your customer will be charged for. There is a possibility to charge up to 12 months in advance.
  • Payment methods – Cash, Credit Card, Bank Transfer, etc;
  • Billing day – a day, when the system issues the invoice and customer is charged;
  • Billing due – the date when non-payer is blocked. The services that customer is using will be still accounted;
  • Grace period – the date when the customer is moved to inactive status. His services will no longer be accounted ;
  • The percentage for your resellers;
  • Billing notifications and reminders 

Our engineers will always assist you in proper billing cycle configuration. Should you have any questions or further information is needed, please contact us or schedule a call with our engineer.

Payment gateways

Charge your customers with Paypal, Braintree,, SEPA, GoCardless, Cashdesk, Payfast or SagePay.

Splynx has a strong billing engine. You can issue Recurring Invoices and send them to your customers or charge customers with Prepay Mode.

Recurring invoicing
Invoices can be issued in advance or in Postpay Mode. One month in advance means that 1st of May Splynx will generate invoices for 1-31 of May. Postpay means that Splynx generates invoices on 1st of May for period of 1-30 of April.

When the invoice is generated there are several methods how to process the customer’s payment:

1. Direct debit order
When the invoices are generated, you can export all or some of them to Direct debit orders. It is available under the button “Charge” in Finance module of Splynx.

Direct debit order can be sent via Splynx module API to these payment gateways: Paypal, Braintree,,
You can also charge your customers’ IBAN bank accounts using SEPA XML and GoCardless platform.

2. Bank statement processing
If customers pay their bills using bank transfers, Splynx can handle these files and process them.


Then the invoice is marked as paid, payment transaction is created and customer’s balance becomes “0”. Because of different formats of the files in banks, we always create a custom handler (php script) which processes our customer’s bank file.

Bank file can be imported manually to Splynx using Bank processing menu, or Splynx can connect to email or bank API and grab file every day or several times per day.

3. Cash payments
Cashdesk is a Splynx module for processing payments.


Administrator can create users of Cashdesk and provide them access to the module. User is not able to change and view any customer’s data, except his name/Company name, Invoice Numbers and actual Balance.

The Cashdesk can be used by accountants, who doesn’t have to get access to Splynx but only process the incoming payments. It can be also used by resellers. Reseller will only see his customers and will be able to enter payments to Splynx when he receives money from customer.

4. Other type, manual processing
If none of above payment methods fits you, there is always an option to add a payment manually in Splynx, or mark invoice as paid. It will create a credit transaction in Splynx and also it will add the payment to customer’s balance.

Prepaid billing
Prepaid billing is used when ISP charges customer in advance and provide him access for certain period of time. When balance of the customer reaches set limit, he is disconnected.

With combination of self-registration feature, customers in ISP network can register themselves on ISP’s website, order a service and pay online for the selected period of time. They can pay via credit cards using Paypal, Braintree or platforms. Braintree even supports Apple Pay, Android Pay and Bitcoins.

Voice Billing

Splynx ISP framework has useful feature to rate phone calls, messages, data and charge customer for voice services. System allows to rate VoIP (Voice over IP) calls, LTE data transfers or work with full mobile phone services that include calls, messages and data.

Customer rating and Provider rating

Splynx can rate calls, messages and data for end user – such rating is called customer rating. Customer rating has own tables with destination prefixes, prices, tariffication steps and other important fields. Based on these data Splynx sets final price for each call, message or data unit.

Also system is able to calculate the cost of each call, message or data unit. This second type of rating is called provider rating and is useful to control voice expenses and understand if our voice/mobile provider has correct charging tables that he applies. The final rating table can have 3 prices in output. Customer price, RBP(rated buy price by Splynx) and CBP (CDR buy price that our provider provides us). Of course RBP and CBP are displayed only to administrator, customer sees only his final customer price. Presence of these prices allows to create custom reports and analyse efficiency of voice services.


Voice plans 

When all rates are set and prefixes with categories are imported, administrator should define voice plans. Each voice plan could have own rate table or multiple plans can share one rate table. If destination is not found in list of prefixes inside rate table, simple increasing of buy price can be applied. Splynx voice billing engine provides flexible configuration of plans, for example defining included amount of minutes per category, amount of free SMS or data that are part of the tariff plan.

Also additional policies can be applied to the rates in group settings of voice plan. For example, it’s possible to change tariffication step for certain call categories or additionally add establish fee.


CDR processing

Our voice billing engine is very flexible in processing of CDRs. Framework can process CDR that are imported manually, but also can be connected to REST API of soft switch. Software can grab CDRs from FTP of voice provider. In next release Radius support will be added. Splynx allows to create custom format handler that will exactly match your CDR format.


When CDR has been processed, Splynx stores voice statistics in different places:

  • Voice processing history, where we can see all processed calls by Splynx in certain day
  • Customer voice service – there are displayed raw per number CDR statistics
  • Customer statistics – these are stats with per category aggregation and with separate displaying of SMS and Data usage. Customer voice stats are available for customer in his portal together with internet data usage.



Rates are configured, Voice plans have been created and CDRs were processed by Splynx. All information about phone calls, messages and data usage is available in customer statistics. The last part of Splynx voice engine is connection phone calls to recurring billing engine. Voice CDR records are automatically attached to customer invoice when next recurring charge is made. Example : we imported CDRs 31st of February for February calls. 1nd of March Splynx runs automatic generation of invoices. All uncovered voice services, calls, messages and data are added to these invoices. Separate debit transaction for voice number is created in Splynx during this process.

Example of such invoice is below :


From version 2.3 Splynx supports auto processing of CDRs and FTP connections to any Voip softswitch or Voice provider that supports FTP for storing CDR files. Learn more about FTP CDR connection –
