Introduction: How Satellite Airtime Billing Works

A typical satellite airtime billing cycle is a complex, multistage process in which there is – unfortunately – plenty of scope for delays and human error. This is especially the case when billing is processed manually using spreadsheets. To create a customer invoice, the following stages are needed:

  • Manually upload the call data records (CDRs) in the file format received from the satellite operator(s)
  • Review the CDRs and clear mediation errors
  • Manually combine the different call charges, value-added services, tariffs, call plans, discounts, roaming charges, uplift fees and
    termination charges into a draft invoice. Sometimes more than one invoice is required if customers are on multiple tariffs, use more than one currency, or require different invoices for various VAT/tax jurisdictions
  • Review the invoice for billing errors and omissions
  • Save the final invoice as a PDF, Word document or Excel spreadsheet
  • Email the invoice to your customer
  • Manually configure a cost of sales and finance report from spreadsheet data

With so many variables in satellite airtime billing, invoicing can rapidly become extremely complex and time-consuming, and prone to billing mistakes and errors.


The results of this are:

Loss Of Productivity:

Staff resources are wasted on
repetitive manual admin, fact
checking and rectifying errors,
rather than productive work.

 Impact On Cash Flow:

Delays in the billing cycle and inaccurate
invoices result in slowness in getting paid. In somecircumstances this can mean that payments to your satellite operators become due before
you receive reimbursement from
your customers.

 Poor Customer Service:

Customers reasonably expect
fast and accurate invoicing from
their service providers. Billing
mistakes and errors damage your
professional reputation, involve
time-consuming and costly
refunds and can, in serious cases,
lead to litigation.

Lack Of Visibility:

Without aclear and unified approach to
reporting, it is very difficult to
manage your margins, making
it a struggle to set competitive
pricing and respond to market
challenges and opportunities.

Investing In a Satellite Billing System

There are several types of satellite billing system available, so before you invest in a new solution it is worthwhile assessing your current business needs. This will act as a guide to the strengths and drawbacks of any systems you consider, and suggest the type of solution you might be looking for.

Your Current Billing Requirements

Take a detailed inventory of your billing requirements and how your current system operates in practice – including the drawbacks leading you to consider a new system. Make a list of the technologies you use – i.e. spreadsheets or an in-house billing system etc. – how the billing system is managed, how many users access the system, and how often you run your billing cycle and generate customer invoices.

  • What is the layout of your invoices and in what document form are they currently provided, e.g. PDF, paper, email?
  • At what level are your invoices generated – at the customer level, per contract, per service type, or per item?
  • How many currencies do you use for invoicing, and which ones? Is one of these designated as a core currency for accounting purposes?
  • Are customer payments made on a contracted, post-service basis, or pay in advance, or a combination of both for different services used by the same customer?
  • Are all your customers on the same invoice frequency, or does this vary? For instance, do some customers receive a quarterly invoice instead of monthly, or only receive a bill when a minimum invoice value is reached? Do your charges and tariffs differ for customers on different invoice arrangements?
  • How does your system generate customer codes, debtor codes, nominal codes and general ledger codes, and in what structure? How is this data passed to your finance system?
  • How does your system generate reports on revenue, costs and margins?
  • How do you calculate prices for each call type and non-call service? Do charges vary between different sources and satellite operators? How do you measure chargeable units – e.g. cost per minute, per kilobyte/megabyte/gigabyte of data? Do you charge a call-start fee or apply an uplift to incoming calls? Are there differences between peak and off-peak rates? Finally, do you apply minimum call charges or minimum call volumes, and for which services?
  • Do you offer your customers a choice of call plans and tariffs? Do these include call or data bundles, free minutes or discounts?
  • How do you process refunds and manual credit or debits?

Your Satellite Operators And Services

The more top-level satellite operators you use, and the more diverse the services from each, the more complicated your billing system becomes. When looking into different satellite billing systems, you want something that can easily handle services provided by different satellite operators, identify varying charges and data formats, and consolidate them into a unified invoice without excessive manual calculations and data entry. The complicating factor when working with multiple providers is the data structure received in different CDR formats, and the way in which they are received. The following considerations will all influence the type of satellite billing system that is best for you:

  • How many CDRs and CDR files you receive per month/billing cycle
  • How many satellite operators you currently work with
  • How many customers and dealers are on your books
  • Your asset base – i.e. the total number of terminals, SIMs and other equipment
  • Mobile installations on ships and aircraft
  • The number of new terminals, contracts and services you add each month/ billing cycle

Your Assets And Installations

How do you track the usage of equipment owned by your business but used by customers remotely, including equipment installed on specific vessels and aircraft? In what format or formats do you receive data on airtime consumption, and in what frequency – e.g. weekly or monthly?

Your Business Goals Over The Next 2 To 3 Years

A satellite billing system, such as SATbill, should be set up to support the needs of your business, not only as they currently stand, but over the next 2 to 3 years. Jot down your plans in the following areas and use it as a benchmark to assess the suitability of any billing system:

  • Revenue goals, sales forecasts and cost indicators
  • New services, products and operational KPIs – e.g. market share, or time to market
  • Structural growth, including expansion of assets, countries of operation, new employees and supply chain partnerships
  • Investment in new IT and telecoms systems (especially relevant are planned investments in accounting, ERP and CRM platforms)
  • Projected trends in satellite technology and significant changes being proposed by your satellite operators
  • Potential risks to your market – e.g. economic downturns, supply chain vulnerability, changes in technology, consumer trends, viral epidemics etc.
  • Changes introduced by current competitors, and potential competitors entering the market over the next couple of years. How will your business differentiate and compete with these companies for the same market share?

What Satellite Billing Systems Are Available?

Broadly speaking there are three types of satellite billing system you can use; a manual, spreadsheet-based system, an in-house custom development, or a specialist platform such as SATbill. Let’s look at each of these options in turn:

1) Spreadsheets/MS Excel

Excel spreadsheets are, in principle, more than capable of handling a satellite billing and invoicing system. However, the more complexities you introduce into your billing requirements (see the previous section above), the more difficult it is to accurately keep track of your billing, and the more time is required to operate your system.

Once your business has progressed beyond a certain size, or you begin working with multiple satellite operators, the negatives of working with Excel quickly outweigh its benefits. One of the major issues is that Excel requires experience and expertise to use its advanced features correctly – and most Excel users only have surface knowledge. This makes frequent and often serious mistakes inevitable.

The other problem is duplication of data. In a billing system in which multiple users update multiple spreadsheets on different shared drives, it’s hard to keep track on who has done what. Information can easily become lost, and data updates can take a long time to filter through the system. This increases the risk of billing errors and delays – with a potentially negative impact on cash flow and your professional reputation.

2) Custom Satellite Billing System

As an alternative to spreadsheets, some companies use a custom-built software platform, designed either by one of their own team, or by a thirdparty software developer. The benefit of this completely tailored solution is minimal implementation time and flawless integration with your legacy systems. However, the price of such bespoke systems can be high, and they can be difficult to update – making them vulnerable to obsolescence and restricting your ability to react promptly to market changes, e.g. major innovations introduced by a satellite operator.

In addition, your custom platform is supported only in so far as you maintain your relationship with the developer. If he or she leaves your employment, or goes out of business, you’re left without support.

3) Specialist Satellite Airtime Billing Solutions

The most cost-effective and practical solution is a satellite billing platform specifically designed for the needs of satellite service providers like yourself. Our SATbill solution falls into this category. SATbill, as we’ll see in the next section, is an adaptable billing solution designed to accommodate complex billing requirements – including multiple call tariffs, invoice cycles, CDR data formats, satellite operators and services.

Using SATbill eliminates the risk of billing errors and radically simplifies the invoicing process, cutting out dozens of hours of administration time when compared to a spreadsheet-based system. SATbill has all the advantages of a completely bespoke platform, with the added benefit of regular updates and in-warranty technical support. Compared to a bespoke system, the lifetime costs are far lower and long-term support more certain.
