What tax filing and invoice verification is
Tax filing and invoice verification is the core of corporate tax compliance: checking invoice validity, matching invoices against contracts, aggregating taxable data and producing filing workpapers. Doing it by hand, invoice by invoice, in Excel is slow and error-prone. MCP Nexus packages invoice verification, invoice-contract reconciliation and workpaper compilation as configurable skills that finance staff run with no coding, clearing a batch in a few minutes with a much lower error rate. Ideal for monthly close, quarterly filing and audit prep.
