Mellistra reads every invoice, investigates discrepancies, follows up with vendors and stakeholders, and delivers ready-to-approve decisions so your team stops doing manual AP work.
Mellistra is the first AP platform that captures, matches & resolves every invoice — including the 25% that break other tools — then syncs it all to your ERP.
87% of invoices at mid-sized companies still arrive as PDFs or paper, and 25% of those turn into exceptions that stall payment, drain headcount, and invite fraud.
Legacy "AP automation" only digitises data entry — clerks still chase mismatches, approvals, and vendors by hand. Mellistra eliminates that entirely.
| Stage | Human AP Clerk | Mellistra AI |
|---|---|---|
| Spot | Notices mismatch after data entry | Flags in real time at ingestion |
| Document Dive | Opens invoice, PO, GR, contract across multiple systems | Cross-checks PO, GR & contract clause automatically |
| Internal Chase | Emails/Slacks budget owners for clarification | Pings the right approver automatically — only if thresholds are exceeded |
| Vendor Outreach | Drafts email asking supplier to revise invoice | Sends vendor email with fix or short-pays if within tolerance |
| Update & Re-route | Manually edits PO or invoice, re-submits for approval | Applies fix, updates ERP, logs audit trail instantly |
| Time Cost | 15–30 min per exception | Seconds (auto) or <2 min (guided) |
| Feature | Others | Mellistra |
|---|---|---|
| Autonomous Agent | Rule-based only; humans handle exceptions | Learns from every invoice and correction — hit-rate climbs while workload falls |
| Active Communication | Ticketing plugin required | Emails vendors & nudges approvers in natural language — no plugins needed |
| Fraud & Compliance | Basic duplicate checks | Duplicate-payment stops, anomaly flags, bank-grade security, tamper-proof audit trail |
| Deployment | Months-long IT projects | Out-of-the-box connectors — go live in <7 days with a 2k-invoice pilot |
| ROI | Unclear payback timeline | SaaS flat fee delivers >5× Year-1 ROI on average |
