Direct answer

What is VoIP billing software?

VoIP billing software collects call detail records from voice platforms and carriers, normalizes and rates each call, applies recurring and one-time charges, calculates telecom taxes, and generates invoices. It can also support wholesale accounts, reseller margins, commissions, payments and customer self-service.

Revenue leakage

Where VoIP revenue slips away

Voice billing problems often begin before the invoice exists. Mediation, rating, tax and channel calculations all have to stay connected.

01

A completed call never becomes a rated charge

Different carriers, softswitches and voice platforms produce CDRs in different formats. Invalid, duplicated or unmapped records create revenue gaps before billing begins.

02

The seat is billed, but the usage is missed

Monthly voice subscriptions may be accurate while international calls, toll-free usage, overages and other variable charges are omitted or rated against the wrong rate deck.

03

Taxes and partner margins are reconciled after invoicing

Communications taxes, reseller pricing and agent commissions introduce additional calculations. When these processes remain disconnected, finance teams inherit manual corrections and delayed settlements.

From usage to cash

From raw CDR to collected revenue

A connected voice billing workflow turns network activity into a traceable charge, invoice, payment and partner settlement.

STEP 01

Ingest and normalize CDRs

Bring call records from carriers, SBCs, softswitches and communications platforms into a consistent mediation workflow. Validate, deduplicate and map records before rating.

STEP 02

Apply the correct rating logic

Rate voice usage by destination, duration, time, service, customer, partner or rate deck. Support prepaid, postpaid, recurring, usage-based and hybrid offers.

STEP 03

Converge every charge

Combine seats, phone numbers, devices, activation fees, recurring subscriptions, call usage, discounts and taxes on one invoice.

STEP 04

Calculate telecom taxes

Connect billing with communications-tax providers and apply taxes and fees based on the service and jurisdiction.

STEP 05

Invoice and collect

Automate invoice generation, payment processing, dunning, account status and collections without rebuilding the usage trail in spreadsheets.

STEP 06

Settle partners and agents

Maintain partner-specific catalogs, margins, commissions and bill-on-behalf workflows across multi-tier voice channels.

Telecom-native billing

Why use a telecom-native billing platform instead of generic invoicing software?

The difference is not the PDF invoice. It is the usage, tax, partner and revenue logic that has to be correct before the invoice is created.

One VoIP billing record across Quote, Revenue and Care

OneBill connects the commercial terms defined during quoting with the service, usage and partner records that drive billing. Finance, operations and service teams work from a consistent customer and revenue history instead of reconciling separate systems after the fact.

Quote

Define the commercial promise

Products, rate plans, partner pricing, commitments and contract terms are established before activation.

Revenue

Rate, bill and protect it

CDRs, recurring charges, taxes, partner economics, invoicing, collections and revenue controls stay connected.

Care

Carry context into service

Customer-facing teams can work from the same account, service, usage and billing context when issues arise.

The same VoIP customer record can move from offer and activation through usage, billing, revenue and service without reconstructing context between systems.

VoIP billing FAQ

Answers to common VoIP billing questions

What is a CDR in VoIP billing?

A call detail record is a usage record generated by a voice network or communications platform. It typically contains information such as origin, destination, start time, duration and call type. A billing system validates and rates the CDR before converting it into a customer or wholesale charge.

Can OneBill process CDRs from multiple VoIP platforms?

Yes. OneBill can ingest and normalize usage records from multiple sources before applying the appropriate customer, service and rate-deck logic. Confirm each required platform and record format during solution design.

Does OneBill support both recurring and usage-based VoIP billing?

Yes. Providers can combine recurring subscriptions, per-seat charges, devices, one-time fees and variable voice usage on the same billing account and invoice.

Can OneBill support wholesale and retail VoIP billing?

Yes. OneBill supports direct subscribers, business accounts, resellers, agents and wholesale partners with account-specific pricing, rate plans, margins, commissions and settlement workflows.

How does OneBill handle telecom tax?

OneBill connects with communications-tax providers so taxes and fees can be calculated using the relevant service and jurisdiction data. The exact configuration depends on the provider’s markets and tax-engine relationship.

Does OneBill replace a softswitch?

No. OneBill is the commercial, billing and revenue-management layer. It connects with voice and network systems to turn service and usage records into rated charges, invoices, payments and revenue workflows.
