Citadel, a modern AI-powered ERP built for mid-market enterprise organizations. Live in 3 to 6 months, not years.
Control your entire financial operation - from general ledger to multi-company reporting - with real-time visibility into every number that matters. No more spreadsheets at month-end.
Run the full order cycle in one place - quotes, confirmations, delivery scheduling, and invoicing - all connected to your inventory and finance in real time. No manual entry, no gaps between systems.
Automate purchase orders, manage supplier relationships, and control spending with 3-way matching that catches errors before they cost you. Every purchase, fully tracked.
Plan, execute, and track every work order from the shop floor - with real-time visibility into materials, capacity, and delivery commitments so nothing slips through the cracks.
Real-time stock visibility across every warehouse location - with serial and batch traceability, stock reservations, and reorder automation so you never run short or overstock without knowing it.
Track every prospect, conversation, and deal in one place - fully connected to your orders, invoicing, and customer history. Your sales team spends more time selling and less time hunting for context.
From onboarding to payroll runs, manage your entire workforce in one system - eliminating manual tracking, missed deadlines, and the compliance risk that comes with disconnected tools.
Every module feeds into a single reporting layer - so you get cross-functional visibility, scheduled reports, and dashboards built from your real data. The Citadel Assistant answers questions using your own business records.
Give customers 24/7 self-service access to their orders, invoices, and support requests. Reduce inbound calls and strengthen relationships with real-time visibility into what matters to them.
Deliver, track, and certify training across your organization, from onboarding courses to compliance certifications, all connected to HR records so every employee's learning history is always current.
Track, maintain, and optimize every physical asset across your organization. Preventive maintenance schedules, real-time availability, and depreciation management keep finance and operations aligned.
Track costs, revenue, and profitability at the project level. Real-time budget monitoring, time and expense management, and milestone billing keep every engagement on track and profitable.
Manage bank accounts, reconcile transactions, and forecast cash flow from one place. Eliminate month-end surprises with real-time cash position visibility across every account and entity.
Create, approve, and monitor budgets by department, cost center, or project. Real-time variance tracking and automatic alerts flag overspending before it becomes a problem.
Most ERP vendors add a chat window to a legacy interface and call it AI. PSI built two proprietary tools directly into Citadel - working alongside your operations using your own data, from day one.
Answers questions using only your data - your suppliers, your contacts, your inventory. Real answers from your own business records, not generic responses from the internet.
Routine tasks do not need human hands. Citadel automates workflows across every module - reducing errors, cutting processing time, and freeing your team for higher-value work.
Workflow automation handles fixed rules. AI Agents handle complexity. They reason through multi-step processes, manage exceptions without prompting, and operate across every Citadel module without a script for every scenario.
Handles vendor invoices end-to-end, from data extraction through GL posting, without manual entry at any step.
Monitors accounts receivable aging continuously, manages tiered outreach, and escalates overdue accounts. No daily staff intervention required.
Works through your month-end close checklist automatically, reconciling accounts, flagging anomalies, and delivering a clean variance report for review.
Watches every item against its reorder point, generates purchase requisitions before you stock out, and follows up on open POs approaching their due dates.
Workflows follow rules. Agents follow goals and adapt when circumstances change.
Every agent operates within your approval structure. Humans stay in control of what matters.
