Every figure on ALKARTIS traces back to a specific public record — which means the first place to check is that record, not necessarily ALKARTIS itself.
ALKARTIS connects and explains public records — it doesn't independently verify or correct them against ground truth. If the underlying source record (OpenDataPhilly payroll data, or an OPA assessment) contains an error, that error can carry through to what you see. See Data Accuracy & Sources for the full explanation of this limitation.
ALKARTIS products make reasonable efforts to keep public-record-derived data accurate and current, but don't guarantee completeness or accuracy, and any figures or comparisons shown are estimates, not promises. For anything critical — especially a property assessment appeal — always verify against your official notice or record before acting.
Compare the figure against the original source: OpenDataPhilly for payroll data, or your official OPA assessment notice for a property record. If the source record itself matches what ALKARTIS shows, the figure is accurate to the public record, even if it looks surprising.
That's worth reporting — reach out through Contact with the specific record and what you're seeing on each side, so it can be looked into directly.
No — figures are derived from public records and carry the same margin of error as the source data itself. See the full Terms of Service for the complete language on this.
ALKARTIS reflects the source record as published — a correction to the underlying error generally needs to happen with the originating city department, not through ALKARTIS.
Usually yes — a mismatch between ALKARTIS and the actual public source record is a genuine issue worth reporting; a figure that matches the source but looks surprising isn't a bug.
