Dueback hunts down overcharges and talks providers down — phone and internet, subscriptions, medical bills, insurance, and more. Free to try. If we can't prove real savings on your actual statements, you pay nothing.
Ten seconds, no signup. Describe a bill that feels too high and we'll run the same negotiability check our AI connectors use.
Point us at the bills you suspect are too high. Takes a few minutes.
Our specialists go to work with your provider — retentions, billing errors, rate plans, the works.
Every dollar is verified against your real statements. You pay only a share of what's proven.
Your AI makes up a negotiation on the spot. Dueback runs category-specific playbooks — retentions, billing errors, rate plans — with escalation paths a one-off prompt doesn't know.
Your AI can't check whether a saving actually happened. Dueback verifies every dollar against your real bank statements, and only charges on what's proven.
Your AI asks once and moves on. Dueback monitors the saving, watches for reversions, and re-negotiates when the deal expires.
And if we can't verify savings, you pay $0 — a generic chat costs you nothing, but it guarantees you nothing either.
Tested head-to-head: In head-to-head matchups against a generic AI assistant, Dueback wins over 94% of the time, with zero losses — and a typical outcome improvement of over 20%.
Fastest path — one prompt. Paste this into Claude, ChatGPT, Grok, Muse, or any AI app that can add an MCP server, and it connects Dueback:

An outcome-based bill negotiation service. Our specialists negotiate with your providers to lower your bills, and every dollar saved is verified against your actual bank statements.
Free to try — no card required. Founding beta members (first 20 cases) pay 10% of verified first-year recurring savings (5% for one-offs), capped at $100 for everyday bills and $500 for big-ticket wins. No verified savings means $0.
Every dollar of claimed savings is checked against your real bank and card statements through a secure read-only connection. You pay only on savings we can prove.
Phone and internet, subscriptions, medical bills, insurance premiums, home services — and dozens more categories.
Every negotiation carries a 30-day reversion guarantee: if a negotiated saving returns to baseline within 30 days of verification, our fee is refunded in full.
Through your AI assistant, through any MCP-compatible app, or directly — email support@dueback.co and we'll start your case personally.
