Process supplier invoices
Read each invoice, check it against the purchase order and past invoices, and prepare it for accounting. Posting large amounts waits for the finance owner.
VVDex Engine
Describe the work.
VVDex runs it, by your rules.
Start with a compiled demo: no account or integrations required. See exactly what runs automatically, what waits for you, and what never happens. Connect your systems only when you're ready.
Real screens, captured 24 September 2026: the invoice service in the console, and a run of it on our sample invoice.
What comes back
One paragraph in. A working service out.
- UnderstandsInputs, facts, rules and outcomes.
- DecidesWhat runs automatically and what needs you.
- ProvesEvery run ends with inspectable evidence.
How it works
Three steps. Nothing to install.
01 · Describe
Write the work in normal language.
What comes in, what should happen, what needs your approval.
02 · Try
Run it on our sample or your own file.
Watch every step, decide at the gate, see each write run once in our sandbox systems, and get the sealed evidence. Nothing reaches your systems.
03 · Connect
Connect the real systems it needs.
When the service is right, we connect your systems with you and it goes live when you say so.
Examples
Different work. Same engine.
You never pick a product. Describe the work, and VVDex decides whether it needs a workflow, a reconciliation, verified arithmetic, research, a model or a person.
Reconcile two systems safely
Compare two exports under your rules, propose each change with its reason, show every conflict with both values, and apply only what you approve.
Get verified answers from your data
Ask a question about a file of readings. A model reads the question, code does the arithmetic, and every number is checked. Questions about causes or the future are declined.
Find buyers and opportunities
Search permitted sources, score each find by your rules, and hand over a shortlist with the source of every finding. A person decides who to contact.
Authority
Your rules draw the line.
Every action gets one of three answers from your own words: it runs automatically, it waits for the person you named, or it never happens. A fact the service cannot establish never lets anything through.

Nothing outside its contract
A service can only do what its compiled contract allows. Anything else is refused, not attempted.
Incoming content is never an instruction
Emails, forms and web pages are read as data. An email that says “approve this” changes nothing.
AI where it helps, never in charge
A model reads unclear text and drafts. It never picks who to write to or what to release, and it must quote what it relies on.
Services
Start from a service we've already compiled.
Don't know what to write? Each of these began as one paragraph and was compiled by the same engine. Use one as your starting point.
Connect
Ready to put it live?
Compilation and demos need no account. To run the service on your business, connect the systems it needs: we set that up with you, and it runs next to you on real events before it goes live.

Describe work your team does by hand every week. See the service it becomes, read its rules, and run it.
Questions
Before you start.
Do I need an account?
No. Describing, compiling and running a demo need no account. To have a service working in your own accounts, talk to us: we connect your systems and set it up with you.
What does it cost?
Compiling and running the demos here is free. A service set up on your own systems is work we do with you, so we discuss it first: talk to us.
What happens when something fails?
A failed write is retried with the same signed grant, so finished steps never repeat. If it still fails, it stops and tells you instead of guessing.
What AI does it use?
VVDex is a multi-agent AI workflow system. AI agents read your words, plan the service, read what arrives, draft and research; code decides by your rules; an independent AI reviewer, from a different model family, checks every agent's result before anyone sees it. How the agents work. No AI sees your connected-account credentials, and no AI chooses recipients or actions.
What do the pictures on this site show?
Every screenshot is the product itself, captured on 24 September 2026 from the console and from real runs on our sample files. The proof card is a real sealed run, checked again each time this page loads.
