Why two bills?

We need an earlier and a latest statement from the same provider to compare billed totals, plans, discounts, fees and dates. BillDelta sends their contents to OpenAI for AI analysis; authorized BillDelta reviewers inspect paid audits.

No Xfinity login or password required.

Before uploading, redact your name, address, account number, phone number, barcodes and payment details where possible. Keep bill dates, plan names, line-item charges and discounts readable. Never include passwords, login codes, bank credentials or full card numbers.

How uploads, retention and deletion work

Uploaded copies are stored privately. They are marked for cleanup after 30 days; cleanup runs during subsequent successful scans, so removal may occur later. Delete uploaded copies using the preview control, or email us for deletion of associated analysis data. Retention & deletion details.

Optional Single Audit: $39 USD, one time. One provider, two bills. No subscription or fee charged by BillDelta for the free preview.

A human reviews your PDF report, then sends it from hello@getbilldelta.com to your checkout email within 2 business days after payment and receipt of two readable bills (Monday–Friday, excluding US federal holidays).

We explain changes and prepare questions and a call/chat script for you. We do not contact or negotiate with your provider, pay your bill, or change your plan. We do not promise a lower bill.

If we cannot deliver the analysis, we refund the audit fee. Refund Policy · Terms · Privacy
