PortaBilling supports multiple billing models:
You can combine these billing models for the same customer. For example, a hosted PBX customer can pay a $50/month recurring fee for a service package that includes unlimited internal calls and 500 minutes of calls to Europe, plus usage-based charges for overages.
A billing cycle defines the interval PortaBilling uses to charge recurring fees and generate invoices. Each customer can choose their own billing cycle from the following:
Yes, PortaBilling supports two mechanisms for this:
Yes. PortaBilling updates a customer’s balance in real time, whether the customer uses prepaid or postpaid balance control.
This ensures the customer uses only what their balance or credit limit allows.
PortaBilling includes several fraud prevention tools to detect and block fraudulent or unauthorized account use. It flags access from an unexpected location, which can indicate a compromised account. It can also block calls from countries you mark as high-risk. Rather than blocking a suspicious call, PortaBilling can route it to a verification IVR, where the caller confirms their identity with a personal code. This way, a legitimate customer traveling abroad isn’t accidentally cut off. If verification fails repeatedly, PortaBilling blocks the account automatically and can notify the customer.
PortaBilling also protects against overspending when an account has multiple active sessions. For example, a customer can stream video, make a call, and send a message at once. PortaBilling reserves part of the balance or service allowance for each session as it starts, which reduces the risk of overspending across sessions.
Yes. PortaBilling serves as a Business Support System (BSS) and Online Charging System (OCS) for mobile operators across all network generations (5G, 4G/LTE, and 2.5G/3G). It covers voice, data, SMS, and value-added services.
PortaBilling can process usage records imported from files, when real-time charging is not available (e.g., for roaming usage in 2.5G/3G networks).
If you run 4G and 5G simultaneously, PortaBilling supports 4G Diameter interfaces (Gy and Ro) alongside the native 5G interfaces.
Yes. You can connect PortaBilling to CRM systems and automate SIM provisioning through PortaFlow. PortaFlow is a managed integration service that connects PortaBilling to other systems through their APIs, so events in PortaBilling can trigger actions in your CRM or network systems, and the other way around.
Its use cases range from simple provisioning tasks to complex business scenarios. For example, PortaFlow can automatically create and sync customer records between your CRM (such as HubSpot) and PortaBilling, reconcile financial data between PortaBilling and your accounting systems, provision SIM cards, and handle eSIM ordering and activation.
PortaOne designs, builds, and supports each workflow for you. Alternatively, your own team can build workflows using PortaFlow’s SDK and CLI.
There isn’t one best telecom billing platform for every provider. A wholesale carrier charging other operators, an MVNO charging mobile subscribers, and a cloud PBX provider charging SMEs have different billing needs. When comparing platforms, consider the following:
The right answer depends on which factors matter most for the services you’re running.
Look for the following when evaluating a telecom billing platform:
Real-time usage tracking works through a continuous check-and-reserve cycle:
The end user can check their balance, which reflects all usage charges. Each usage event is also recorded as an xDR (extended detail record), the record used for invoicing, reporting, and dispute resolution.
A vendor-managed cloud billing solution runs on infrastructure maintained by the billing vendor, offering several practical benefits:
Operators with specific regulatory requirements or a preference for direct control over their infrastructure may find an on-premises deployment more suitable.
Start with your MVNO model, as that shapes your platform requirements and budget. A thin (reseller) MVNO rents the host operator’s network core and owns a billing platform. A full MVNO runs its own network core with its subscriber data and owns a billing platform. PortaBilling supports both as a BSS and online charging system (OCS).
Before comparing platforms, consider both the capabilities you need, and the support you expect from the billing vendor.
What the platform must do:
What to expect from the billing vendor:
An MVNO billing platform may also need to support:
PortaOne starts every migration with an analysis phase. A business analyst documents your requirements, maps them to PortaBilling functionality, and identifies feature gaps. The analyst also reviews the systems connected to the billing platform, such as CRM systems, provisioning platforms, and self-care portals. A migration engineer analyzes the source files exported from your legacy system and maps the data to PortaBilling. You then receive a scope of work that defines what will be migrated.
You choose how to migrate:
Whichever option you choose, it is common practice to migrate customers in batches. During the migration, the legacy platform and PortaBilling run in parallel. Each batch is validated against the legacy system before the next batch starts.
The timeline depends on the size of the customer base, the complexity of the products, and the number of integrated systems.
Replace your spreadsheet or in-house billing system when manual work and system limitations slow business growth or cost you revenue. Common signs include:
Before replacing a billing system, ensure the new platform reduces manual work, eliminates the need for programming, and scales as your business grows. Plan the migration too, because it affects how fast you can switch.
