Tax and government revenue teams usually already hold the records that point to underdeclaration, non-compliance or misallocated funds. The gap is rarely data availability. It is having a consistent, defensible way to turn large volumes of filings, transactions or disbursement records into a manageable, prioritised caseload that auditors and enforcement teams can actually work through.
Ledger Core is the part of Vantage that does that triage and case management for you. You send your data in, the platform scores it, and your audit or compliance team gets a working case queue instead of a raw dataset.
Every record you upload or send through the API passes through Vantage's scoring pipeline. Records that show a pattern worth investigating are assessed by AI and, once they cross your configured threshold, set to 60 by default and adjustable per tenant, created as a case in your queue. Each case comes back with a risk score from 0 to 100, a risk band of critical, high, medium or low, a confidence level, one or more flags, and a plain English explanation of why it was flagged. An investigator can trigger a re-score on any case at any point and see the score history right on the case page. Scores are decision support for your investigators, not an automated decision: a case is reviewed by your team before any action is taken on it.
A sortable, filterable case queue sits at the centre of Ledger Core. Every case can be assigned, re-assigned, moved through statuses such as open, under review and resolved, and set to a priority level. Investigators keep a threaded notes panel on each case, and any note can be marked internal only or left visible in the field work orders, with the author's name and timestamp attached automatically. Every meaningful action on a case, from a status change to a re-score, is logged to a full audit trail that sits alongside the case and travels with it into any export.
When a case is assigned to someone, an email goes out automatically, carrying your organisation's name alongside Vantage module branding, with the case reference, risk score, value at risk and a direct link, so nobody has to check the platform to know work has landed on their desk. Each investigator also gets a personal "My Cases" inbox showing only their open and under review cases, sorted by priority and then by risk score, so the highest value work is always at the top.
Any case can be exported as a PDF in one click, carrying your organisation's name alongside Vantage module branding. The export carries the risk score, identity and confidence details, the value at risk, a full AI explainability breakdown, the evidence table where one exists, the recovery log, every investigator note, and the complete audit trail. It is built to stand on its own in an audit, legal or parliamentary accountability context, not just as an internal summary.
Once a recovery is confirmed, it gets logged against the case with the gross value recovered, giving you a clear, auditable record of what has actually been recovered rather than an estimate reconstructed after the fact.
An administrator can manually trigger a field audit or inspection dispatch directly from any case, sent as a signed, one-time request to whichever field management or case system your agency already uses, connected through a webhook you configure in settings. The dispatch, its destination and the response status are all recorded in the case's activity log, so there is never any doubt about whether an order actually went out.
Instead of building a report or waiting on an analyst, anyone on your team can ask Ledger Core a plain English question about their case data and get an answer straight back. It is built for the auditors and compliance staff who actually use the data day to day, not for people comfortable writing queries.
Ledger Core includes REST API access as standard, using a bearer token unique to your tenant. You can score a single record, or send up to 100 in one batch call, directly from your own filing, payment or disbursement systems. A public sandbox with pre-scored demo records and live documentation is available so your technical team can evaluate the API before committing to anything.
Every capability described above is available either way. What changes is how you pay for it.
Both are Ledger Core: same scoring, same workflow, same everything above. The only difference is how the bill is worked out.
Ledger Core is a cloud-hosted SaaS platform with role-based access, so there is nothing for your team to host or maintain. Data comes in either through the upload manager or the API, sourced from your existing filing, payment or disbursement systems. Once your application is approved, a new tenant can be provisioned in minutes, with sandbox demo data available immediately so your team can start evaluating the platform before a single real record is uploaded.
Core Volume and Core Value above are two ways to pay for Ledger Core, the same product either way. Ledger Score is a different, lighter product: API-only scoring without the case investigation workflow described above, available separately for teams that just want to plug Vantage's risk engine into an existing system.
