Our Bill Verification and Assessment Services
Utility Bill Verification
We verify utility bills for electricity, gas, water and more by cross-checking consumption data, meter readings, tariff schedules and billing calculations.
Our energy audit services can then help you reduce the consumption behind those bills.
Verification of Contracted Rates
Our team reviews supplier agreements and service contracts to confirm that invoices are based on the agreed prices, discounts and payment terms.
Confirm Invoice Accuracy
Each invoice is checked for mathematical accuracy, unit rates, quantity calculations, taxes and other charges.
Assessment of Consumption
We review prior consumption history for spikes, usage irregularities and possible billing irregularities, checking readings against how an electricity meter records usage.
Financial Impact Analysis
If there are discrepancies, we analyze the financial impact and provide detailed documentation to back up your recovery claims or your discussions with suppliers.
Audit Findings & Recommendations
Clients receive a full report of findings, discrepancies, financial impact and recommended corrective actions.
Our Bill Verification and Review Process
A systematic process ensures that every bill is reviewed properly and recorded properly.

Step 2: Data Check
Billing is checked against contract agreements, tariff schedules and usage records.
Step 3: In-Depth Verification

Step 4: Calculate the Differences

Common Billing Errors Identified in Third Party Verification
Most organizations think billing errors are rare. However, in our experience, mistakes happen because of manual calculations, outdated tariff information, system errors or misinterpretation of contract terms. Small differences, repeated month after month or year after year, can add up to big financial losses.
Third party verification reveals common billing issues such as the following. Electricity and gas tariffs in Bangladesh are set by the Bangladesh Energy Regulatory Commission (BERC), and VAT rules are issued by the National Board of Revenue (NBR).
Wrong Tariff Category
The utility provider or service vendor may have placed your account under the wrong tariff category and charged you rates above the agreed or allowable rates under the applicable regulations.
Double Charges
If you have multiple accounts or locations, you could be billed more than once for the same service, equipment or utility consumption.
Mathematical Mistakes
Simple calculation errors, wrong totals or rounding errors can affect the amount of the final invoice.
Wrong Meter Readings
Incorrect manual readings, faulty metering equipment or estimated consumption may result in over billing or under billing.
Differences in Contract Pricing
Invoices should always show the prices, discounts and payment terms specified in the contract. Any deviation should be checked carefully.
Incorrect VAT and Tax Calculations
Mistakes in VAT, supplementary duties or other applicable taxes can result in unnecessary costs and compliance headaches.
Unauthorized Additional Charges
Some invoices may include administrative fees, service charges or penalties that were not agreed to in the original contract.
Charges for Services Not Rendered
Sometimes, businesses keep paying for services that are no longer required or have been discontinued.
Identifying these issues early allows organizations to improve financial control, reduce unnecessary expenses and increase vendor accountability.
Why You Should Get Independent Bill Verification
Internal finance teams typically process hundreds of invoices each month. Because of operational priorities and workload, a detailed line-by-line review of every invoice is not always feasible.
An independent third party review provides:
- Objective and unbiased verification
- Increased confidence in the financial statements
- Greater transparency for stakeholders
- Improved internal controls
- Lower financial risk
- Better vendor management
- Audit-ready documentation
- Opportunities to recover overpayments
An independent audit provides an additional check on spending to ensure companies are only charged for valid and correctly calculated expenses.
