I Just (As Of Tonight) Went Online To Get Started w. This Company. However, I Am Now Discouraged Due to The Reviews Which Are 90% Negative. I Hope They Haven't Already Pushed The Fees Through On My CC/. I Will Definitely Be Reconsidering/ Changing To A More Trusted & Better Business w. An A-1 Reputation. I Definitely Can't Even Afford To Risk Any Losses Like Explained By Both Previous & Current Customers. Sooooo...
Thanks In Advance Everyone For You're Honest Reviews. I'm Glad I Went w. My Gut & Decided To Check Out These Reviews!!!

Hi there — we’re sorry to hear you felt discouraged. Based on the details in your review, it doesn’t appear that our service was actually used or that any fees were processed. Billshark does not charge upfront; fees are only applied after savings are successfully secured, and customers are notified before any negotiation begins.

Read the details before you commit!
I used Billshark through the PocketGuard budgeting app. I read up front that they take a 40% cut of your savings. What I failed to look into was how exactly they bill this. It's shocking to receive a bill in the HUNDREDS when you're trying to SAVE money. They ended up saving me money without canceling any services, although they were trying to do that at first and I told them I did not want any services taken off of our bills, I just wanted the reduction. And to their credit, they were able to do that. But the reduction periods can be for years, and they will bill you for 40% of the savings over those years! Fore example, they were able to save me $300 over the course of 2 years off my phone bill. So you get charged for 40% of YEARS worth of savings. They say just enough up front so that they can't be accused of the bait and switch, but they conveniently leave out details about how EXACTLY you will be charged. I also received a message saying they will re-negotiate for me automatically once the savings period is over. No thanks!!!!!! I had to email them asking them to not automatically renew this service. I feel trapped now and taken advantage of. I don't recommend using them.

We understand how surprising a larger invoice can feel, especially when you are trying to save money. Since you enrolled through PocketGuard, you received our standard welcome email for each negotiation request you submitted, and I see all three were opened on the same day they were sent. Those emails explain how our fee works, including that we charge 40 percent of the total savings secured, capped at 24 months, and that the fee is billed once the negotiation is completed.
You also mentioned concerns about services being removed; however, your negotiator followed your instructions and secured reductions without changing or canceling any part of your plan.
The automatic re-negotiation you referenced is part of the service, and you can opt out at any time by replying to the notification or letting us know at any time, which you already did.

Great service, too expensive
Its a great service but they take waaay too much money. They negotiated me $600 in savings that I will accumulate at $50/month and took $240 of it immediately.

DO NOT USE THIS COMPANY!!!
DO NOT USE THIS COMPANY!!!
First, I originally left positive feedback for this scam company. Now, not so much. I was told that they lowered my Xfinity/Comcast bill by $48.00/mo. for 1 year. After a couple of months, my bill is still the same. I contacted them and was asked to send in my bills for Feb., March and April. I sent the top page with the amount. That was not good enough. I had to email the entire bill. Why? I don't know. The total savings was $576.00. They then take 40%= $230.40. I have to hope I get refunded. However, I used paypal and I have it in writing that they will refund my payment.

Thank you for reaching out and sharing your concerns. I understand your frustration and want to clarify a few important points.
We requested full billing statements — not just the cover pages — to thoroughly verify whether the savings we negotiated were actually applied. Without the full breakdown, we’re unable to confirm if the rate changes took effect or if other provider-side adjustments impacted the total.
Given your background in real estate I'm sure you are familiar with how important it is to review full documentation before drawing conclusions, I’m sure you can appreciate why a cover page alone isn’t sufficient for any verification process — this ensures accuracy and fairness on both sides.
You were quoted $48/month in savings, totaling $576 over 12 months. Our one-time fee of 40% came to $230.40 and was only charged after the negotiation was completed.
That said, your refund has already been processed, and you should see it reflected back to your PayPal account shortly.
We appreciate your initial support and your patience throughout this process. If you have any additional questions, feel free to reach out.

They “Negotiated” my AT&T cellular…
They “Negotiated” my AT&T cellular bill. All that was done was removal of an add on. Hardly worth paying $98 for. Absolute scam. Please avoid this company for they will only do what you can do for free on your own. Even after I told them to leave everything alone I still get charged because there is “savings” even though I’m not accepting their changes.

Total scam
Total scam. Billshark invoices based on a percentage of the “savings” they negotiate on your behalf. In my case, Billshark is claiming that they saved me a ludicrous amount, and they are unwilling or unable to give me a list of where their calculated savings are coming from. My negotiated bill is within $10 of my previous bill, but they are claiming they saved me $600. I’m being invoiced for several times more than the change to my bill, and Billshark cant back up where their numbers are coming from. As far as I can tell theyre totally made up.
EDIT: Their reply below is also totally false. Yes their pricing structure is clear and they did send me a breakdown of their numbers, but their numbers are 100% demonstrably incorrect— theyre looking at the incorrect values. They can just say they saved you $5000 and theres nothing you can do about it even if its not reflected in any statements or future billing projections. Their customer service also just stops responding, and they refuse to escalate internally. Their “escalations” are just transferring you to another front line service rep. Stay far away.

Thank you for sharing your concerns. We understand your frustration and want to assure you that our Customer Service team is actively working with you to address this matter. Our goal is always to provide transparency and ensure you have a clear understanding of how your savings were calculated.
To clarify, our fee structure is fully transparent and clearly listed at sign-up and checkout. Our fee is 40% of the total savings achieved, capped at 24 months. This fee has never changed and is the same structure that was applied during your previous negotiation last year.
Additionally, on February 12, 2025, we sent you a detailed breakdown of your savings. I also see that you received and opened this email multiple times. Our fees and savings calculations are always transparent, and we are happy to review your specific case in detail to ensure accuracy.
We hope to resolve this issue to your satisfaction and appreciate your patience as we work through it. Please don’t hesitate to continue working with our team so we can clarify any discrepancies and find a solution.

Do not use
Do not use. They'll sit and sit on your claim until you forget about it and then completely ignore what was asked and Make-up absurd savings so they can charge you whatever they want.
Update to their response:
In regard to their response below, they didn't respond... it's been a while now, but I believe well over a month or even several months before they took any action. I figured nothing was happening with their service and then they proceeded without consulting me further and did something I did not ask for at all. They basically did the opposite of what I wanted done and then tried to charge me nearly 500$ for it.
I responded many, many times to them, called them on the phone a number of times, etc. as well as fought with my bank and neither would reverse the charges. Bank has some contract with them direct, so be careful.

We took proactive steps to address your issues after the conversation you had with the Shark that negotiated your bill and our Customer Success team reached out to resolve your concerns.
Unfortunately, we didn't receive a response.
At Billshark, our mission is to save our customers time and money, not increase costs or hassle. It appears that we were in direct contact with you during the negotiation and acheived what you had requested.
We will try to contact you again to work together and make things right. Your satisfaction matters, and we value your business.

For several years these sleezy people…
For several years these sleezy people pretend to be customers or potential customers for our business.
They send requests for customers that do not exist. I have emails (spoke on phone as well) H. H....S (no longer with you guys) over there, who promised the harassment and sleezy behavior would stop.
As a point of order - we never discuss customers' accounts with strangers and have never actually had a bill shark discuss an actual customer.
I see from the real reviews for Bill Shark - you guys rip off your customers.
Really sleazy. I will reach out to management again.

Hi Jonathan! I can't seem to find you in our system and based on your comment you appear that you may be a service provider. If so, then it looks like we're accomplishing our goal in taking money back from you for your customers! The providers have been grossly overcharging customers and we are here to even the playing field! This is the best review we've read in years! If we're making you (the provider) angry, then we are doing our jobs! ;-)
