Find sales and use tax your business paid but may not owe. Trace every recovery dollar to invoices, rules, deadlines and qualified human review.
Tenant-scoped scans → exact decimal findings → evidence and rule binding → human approval → vendor recovery tracking.
Create a bounded legal-entity and jurisdiction scan, inspect potential findings, require evidence-bound human approval, and track recovery. OCR, complete rule packs, and authority filing are later phases.
Capabilities
Potential overpayments by invoice line
Recompute charged and correct tax with decimal arithmetic and preserve the proposed recovery amount.
Evidence and rule binding
Approval fails until source hash, rule hash, and effective rule version are attached to the finding.
Human-controlled review
No model-generated operation may approve a finding or begin recovery operations.
Deadline-safe totals
Expired findings remain in history but are excluded from actionable portfolio totals.
Recovery operations
Track approved vendor contact, response, assignment, credit memo, refund, denial, and permitted escalation states.
Install
Hosted pilot — log in at dashboard.html#refundproof. No autonomous filing and no guaranteed recovery.
Pricing
Initial opportunity scan: free. Recovery review and operations: pathway-specific pilot quote after coverage, evidence, and professional-review requirements are confirmed.
