Spend Intelligence for Procure-to-PaySpend intelligenceAI invoice captureClaude AIComing soon

Most AP tools show you what you spent. Inostos shows you what to do about it.

Inostos finds the money leaking from your spend — duplicate suppliers, category creep, off-PO invoices and contracts about to auto-renew — built on a complete procure-to-pay foundation for growing finance teams.

Inostos
The most important thing we're building

Spend intelligence, built in

Built for businesses that have no real visibility or control of their spend today — and don't want blunt automation. They want the system to tell them where the problems are, and what to do about them.

Duplicate & near-duplicate spend

Flag the same thing bought twice, the same supplier under two names, and overlapping subscriptions nobody remembers.

Category & supplier trends

Surface where spend is rising, which suppliers are taking a growing share, and where consolidation would cut cost.

Off-PO & above-tolerance spend

Invoices with no matching commitment, and spend drifting above approved values — flagged before they're paid.

Auto-renewal detection

Watch the payment stream for contracts about to renew themselves — before they do. Detected contracts flow into Timemy.

The difference from every dashboard: Inostos won't stop at a chart. It will propose the next step — consolidate these two suppliers, review this renewal, challenge this price rise.

AI invoice extraction
Claude AI reads PDFs, scanned documents and structured e-invoices — extracting supplier, amounts, VAT, IBAN and line items automatically. No templates, no manual keying.
PO approvals & auto-matching
Departments raise purchase orders digitally. Inostos routes each PO to the correct approver by value, then auto-matches the arriving invoice to the approved commitment.
PEPPOL & e-invoicing ready
Inostos is built to receive and process structured e-invoices natively — PEPPOL BIS 3.0, UBL 2.1 and Factur-X — alongside PDFs. Built for what regulators are already mandating.
Email inbox sync
Connect your AP inbox and Inostos will scan every email automatically, pulling invoice attachments — PDFs, XML and PEPPOL formats — into the workflow without manual intervention.
Supplier fraud controls
Every change to a supplier's bank details is flagged and held for secondary approval. First-payment holds, Confirmation of Payee, and anomaly signals — standard, not a bolt-on.
Real-time AP dashboard
Live visibility across the full AP cycle: POs awaiting approval, invoices under review, overdue liabilities and upcoming payment runs — all in one place.
Three-way matching
Record goods or services received against an open PO. Inostos performs a three-way match — PO, goods received note and invoice — within configurable tolerances.
Full audit trail
Every approval, status change, payment export and supplier edit is timestamped and attributed. Immutable records designed for audit and SOX-aligned controls.

How it works

A rollout that respects your ERP and your team’s time

We keep it practical: prove value quickly, then expand.

Step 1
Discovery
Raise the purchase order
Any team member submits a purchase request with supplier, items and estimated value. Inostos routes it to the correct approver by value — no emails, no spreadsheets.
Step 2
Build
AI captures the invoice
Invoices arrive by email, upload, or structured e-invoice (PEPPOL/UBL/Factur-X). Claude AI extracts every field automatically — supplier, amounts, VAT, IBAN — with no templates.
Step 3
Go-live
Match, approve, and flag
Matched invoices auto-approve within tolerance. Inostos flags duplicates, off-PO spend and anomalies before they reach payment. Spend intelligence surfaces patterns across the full history.
Step 4
Optimise
Payment file and ERP sync
Approved invoices post to Xero, QuickBooks or Sage X3 with correct coding. Inostos generates the payment file and hands off to your bank — it does not execute payments.
Signature capability

Auto-renewal detection — before the contract renews itself

Inostos watches the payment stream for the signatures of auto-renewing contracts — recurring invoices, fixed monthly suppliers, commitments that repeat on a cycle — and flags them before they silently renew.

A standalone AP tool has no contract product to hand off to. A standalone contract tool has no payment data to detect from. Because Hidbrain builds both, Inostos does what neither can do alone.

Detected contracts flow into Timemy — Hidbrain's contract-renewal platform — for full clause tracking, notice-period alerts and renewal management.

EU data residency, AES-256 encryption at rest, TLS 1.2+ in transit, row-level data isolation, immutable audit trail, and segregation of duties enforced by the platform. Inostos generates payment files and exports them to your bank — it does not hold funds or execute transfers.
