Why teams switch

Accounts payable that checks itself — and a person who decides

Manual matching is slow, and the mistakes it misses cost real money. AI Matrix does the reading and checking so your team only handles what matters.

Reads any supplier document

PDFs, scans, photos, Excel and CSV. Every header field and line item, with a confidence score on each.

Matches invoices to POs

Pairs each invoice with its purchase order by number, then compares every line — price, quantity and SKU.

Risk signals before payment

Flags changed bank details, duplicate and look-alike invoices, and vendors that aren't on your list. A person makes the final call.

People stay in control

Approve, hold, reject or request a correction. Amount-based limits make sure the right person signs off.

Audit trail you can trust

Every document, check, view and decision is logged with who and when. The log is append-only — nobody can edit it.

Fits your accounting stack

Approved invoices go out as a signed webhook or a CSV import. Native QuickBooks Online and Xero connectors are next on the roadmap.

How it works

From inbox to approved in four steps

  1. Step 1

    Send documents

    Forward supplier emails to your workspace address, or drag in PDFs and spreadsheets.

  2. Step 2

    AI reads and matches

    Each invoice is read line by line and matched to its purchase order automatically.

  3. Step 3

    11 checks run

    Prices, quantities, totals, dates, duplicates, vendors and bank details are checked against your rules.

  4. Step 4

    People decide

    Clean invoices route by amount. Exceptions come with a plain-English explanation and the evidence side by side.

11 checks before approval

Every invoice checked against your rules.

Set your tolerances once. AI Matrix checks every invoice consistently and sends anything outside your rules to a person for review.

What your team sees

When an invoice doesn't match, you see exactly what and why.

No digging through PDFs. The exception shows the PO price, the invoice price and the money at stake, and goes to the person your approval rules name.

  • Routed by amount — for example, Manager approval over $10,000
  • Payment waits until a person approves, holds, requests a correction or rejects
  • Every decision is saved to the audit trail

Your price tolerance is ±1%. This line is 7.8% over the PO, so the invoice waits for a person. At $23,219.63 in total, it needs Manager approval.

Built for finance teams that can't afford mistakes

Your documents stay yours. Every decision is on record.

Read the security overview

Separate workspaces

Each company's data is isolated in the database itself, not just hidden in the app.

Bank numbers never stored

We keep a one-way fingerprint to spot changes, plus the last four digits.

Human approval

Only clean invoices under your limit, from vendors with verified bank details, can skip a person — and only if you switch it on.

Append-only audit log

Every read, check, view and decision is logged and can't be changed.

Role-based access

Owners, admins, approvers, reviewers and viewers each do only what they should.

Encrypted & private

Encrypted in transit and at rest. Files are shared only through short-lived links.

Questions, answered

Do we need to change our accounting system?+

No. AI Matrix sits in front of it. Approved invoices are sent through a signed webhook (Zapier, Make, Power Automate or your own service) or exported as CSV. Native QuickBooks Online and Xero connectors are next.

Will the AI post anything on its own?+

Not unless you switch on auto-approval, and even then only for invoices that pass every check, come from a known vendor with a matching bank account, and are under your limit.

What documents can it read?+

PDF invoices and purchase orders (digital or scanned), photos (PNG, JPG, WEBP), and CSV or Excel files, up to 25 MB each.

How is our data protected?+

Each company's data is separated at the database level, files are private, bank numbers are never stored, and every action is logged. Documents are read with Anthropic's Claude API, which doesn't use API data to train its models by default. See our security page for details.

Is this fraud detection?+

No. AI Matrix raises risk signals — a changed bank account, a duplicate, an unknown vendor — and a person decides. It never pays anyone and never changes bank details on its own.

How does the 14-day pilot work?+

Day 1 we set up your vendors, approval limits and email forwarding together. Days 2–3 we load last month's documents; from day 4 new invoices flow in live. On day 14 you get a scorecard: documents processed, match rate, money flagged and time saved against the goals we agreed on day 1.
