  4. Billing for specialty numbers such as incoming Toll-Free numbers and premium
    (900,976) numbers.
  5. Billing for combined usage from multiple lines for corporate and family plans.

  1. Asterisk

  3. NetSapiensAdvanced
  4. Frontier
  5. EMI_Voyant

CDR Billing Plan

A CDR Billing plan contains the information necessary to bill using data from CDRs to rate Long Distance calls, sum Plan Minutes, bill for N11 calls, etc. A plan is attached to a Package or Service definition. Create one or many CDR Billing plans to accommodate the billing needed.

Internal Tax Engine/Avalara

BillMax allows you to choose how taxes are maintained and calculated. One option is the BillMax internal engine to enter the necessary Tax Regions and Tax Items. BillMax also supports managing Universal Service Fund (USF) assessments, both the Federal and State portions. This includes support for reporting to the managing entities such as the Universal Service Administrative Co. (USAC) and passing assessments through to the end customer. Tax on tax is also supported. Taxes are based on the Service location of the customer and the type of product.

If your company provides service to many tax regions or filing help is desired, use our third party integration with Avalara. Update each Package/Service Definition with a transaction pair that tells Avalara what you are providing to the end customer. As the transactions are created, BillMax will send them to Avalara and receive the taxes and fees back. They are automatically shown on the bill at a detailed or category level depending on your setup.

  3. CDR Billing Usage shows the detailed billing lines for CDRs for a particular package/service, invoice, billing statement, or transaction.
  4. Future CDR Billings lists the CDRs that are outstanding for a particular account.
