Telecom cost reduction: four carrier bill charges to dispute

The quickest telecom cost reduction does not need a new carrier or a new contract: it is getting credit for charges you should not be paying. Four kinds of line on a carrier invoice qualify, and you can find all of them with the invoice, last month's invoice and a list of what you disconnected.

This guide describes each kind, how to put a dollar figure on it, and how to raise it with the carrier. It does not promise savings: what you find depends on your bills.

Where does telecom spend leak on a carrier bill?

In four places, ordered here by how much each tends to cost over time:

1. Services billing after you disconnected them.
2. Recurring rates that changed.
3. Lines billed twice.
4. One-time charges that repeat.

A fifth thing is not a leak yet but deserves a look: a new recurring line you do not recognize.

What is a charge after disconnect, and how do you size it?

It is a recurring line, such as a circuit, a SIP trunk or a mobile line, whose service ID is on your disconnect list and whose billing period ends after the date you disconnected it. It matters most because it repeats: the same line charges again every month until someone notices.

To size it, take the line amount and multiply by the number of months since the disconnect date. The monthly figure alone understates it. Where the period starts before the disconnect date, the carrier may be prorating the last month, so count only the days after the date. Whether and how far back you can get a credit depends on the carrier and your contract, so check both before you quote a total.

How do you size a rate change?

Compare each recurring line with the same service ID and description last month. Where the rate differs, write down the old rate, the new rate and the difference, and multiply the monthly difference by 12 for the yearly figure. A circuit that rises by $20 a month is $240 a year.

Be precise about what you found. A flagged rate change is a change, not proof of an overcharge: the carrier may have the right to raise it under your contract. It shows you which ones to ask about. Ignore tiny moves by requiring both a percentage and a dollar threshold, for example 10% and $5 a month.

How do you find a line billed twice?

Look for two lines with the same service ID, description, period and amount, within one invoice or across two invoices from the same carrier and month. Across invoices is the case people miss: a summary PDF and a detail export of the same bill can show the same line, so make sure you are comparing separate bills and not two views of one.

The size of the duplicate is the amount of one copy.

What is a repeated one-time charge?

A charge that should appear once, such as an install, a reconnect fee or a credit reversal, showing up in two consecutive months for the same service ID and amount. Sometimes it is legitimate (a second install), so treat it as a question to the carrier. The size is the amount of the second one.

How do you dispute them?

Send the carrier one note per account that lists, for each finding:

• the billing account and invoice number;
• the service ID and the line as printed;
• the amount;
• the reason: billed after the disconnect date of a given day, rate changed from one amount to another, duplicate of a line, or a repeated one-time charge.

Use the dispute channel your carrier gives you, keep the date you sent it, and record whether each finding was credited, still disputed or dismissed. The next bill should show the credit.

What can you not find this way?

An invoice check does not read your contract, so it cannot tell you a rate is above what you agreed to. It does not validate taxes and surcharges, analyze usage, or find services nobody recorded. For those, see the telecom audit guide for when to bring in an auditor, and the telecom expense management software guide for the platform route.

How Carrier Bill Check finds these charges

Carrier Bill Check runs all four checks on the invoices you upload, as PDF, Excel or CSV, and lists the findings with the dollars at stake: the amount billed and the running total since the disconnect for a charge after disconnect, old rate, new rate and yearly difference for a change. You get a CSV of the open findings and a dispute note per carrier to send yourself. It never contacts a carrier, and it does not promise a saving: the sample on the free run shows what a finding looks like, and your own CSV or Excel invoice shows its lines and any duplicates. To make this a monthly habit, use the telecom expense audit checklist.

Frequently asked questions

Do I need a telecom expense management platform to cut telecom costs?

Not to find these four charges. A platform covers more, including contracts and inventory, and ITG Group's guide to telecom expense management gives $500-2,000 a month for lightweight ones. A line-by-line invoice check is the smaller step.

Will I get a credit for every charge I dispute?

No. A carrier may credit, refuse or credit part of it, and a window may apply. That is why each finding is tracked as disputed, credited or dismissed.

How often should I look?

Monthly, as each invoice arrives. A charge after a disconnect repeats every month, so each month you wait is another month to dispute.
