Owner Founder Wholesale ### "Very Poor Support and Incorrect GST Calculation" 1.0 Overall Rating 1.0 1.0 Ease of Use 1.0 1.0 Features 1.0 1.0 Customer Service 1.0 1.0 Likelihood to Recommend 0/10 May 1, 2026 I am running Vishwas Sales Agency and used Kernel Billing Software for billing purposes. Unfortunately, due to incorrect GST calculation in the software, I had to pay excess GST which caused financial loss. I contacted their support team multiple times and made more than 50 calls, but no proper response or solution was provided. They promised a refund, but even after 18+ days, the refund has not been processed. This kind of service is highly unprofessional and disappointing. It has created financial and operational issues for my business. I would not recommend this software to other business owners. Pros You can keep it simple or neutral: Easy to use interface for basic billing Initial setup is simple .. Cons 👎 Cons (What did you like least about Kernel?) Incorrect GST calculation caused financial loss No proper customer support 50+ calls made but no response or resolution Refund not processed even after 18+ days Unprofessional handling of customer complaints Switched from [myBillBook](https://www.capterra.com/p/202732/FloBooks/) I switched from manual bill book to billing software to make my billing process faster, more accurate, and GST-compliant. I expected the software to handle GST calculations correctly and reduce manual errors. However, my experience has been disappointing due to incorrect GST calculations and poor customer support.
