Invoices

What this skill does

Files, checks, and audits the invoices you receive: OCR and e-invoice XML, duplicate and fraud checks, VAT deduction, and a searchable archive. Use when an invoice, bill, or receipt arrives as a PDF, photo, email attachment, or portal download and has to be filed; when asked where an old invoice is, or what was spent with a supplier last quarter; when preparing a VAT return or an export for an accountant; when an invoice looks wrong, duplicated, or larger than usual; when a supplier's bank details changed on the document; when a recurring invoice never arrived; and when a credit note, reverse charge, import VAT, or a foreign currency has to be booked correctly. Covers Factur-X/ZUGFeRD, XRechnung, Peppol, supplier normalization, and retention mandates. Not for issuing invoices to your own clients (`invoice`), tracking personal spending (`expenses`), chasing a client who owes you money (`clients`), or building a billing system (`billing`).

Invoices is part of the Developer Tools category — developer tools that help your agent write, review, debug, and ship code. You can install it on its own or alongside other developer tools skills from the OpenClaw catalog.

How to install Invoices

The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:

1. Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
2. Open the in-app Skills panel.
3. Search for invoices and click Install.
4. The skill activates automatically when an incoming message matches its description.

Install from the command line

If you already run the OpenClaw CLI, add Invoices with a single command:

openclaw skills add invoices

This pulls invoices from ClawHub and installs it into ~/.openclaw/skills/invoices/. Restart the OpenClaw gateway afterwards so the new skill is discovered.

How to use Invoices

Once installed, Invoices activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.

Turning images into video

Invoices works with images. Getting from there to something postable is a separate job: ViralMint — an open-source video pipeline — turns stills into motion — pans and transitions, synced captions, and a vertical export for short-form feeds.

It runs as an MCP server, so an OpenClaw agent can drive it from the same chat you already use: ask for a short, and the render comes back finished. See how to connect a video pipeline to your agent.

Manual install (advanced)

If you prefer manual installation:

1. Click the Download .zip button above to grab invoices-1.0.3.zip directly from our S3 mirror.
2. Unzip into ~/.openclaw/skills/invoices/ (create the directory if it does not exist).
3. Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
