What it does

Before the accounting export, an invoice without a document cannot be booked or audited.

Instead of checking invoice by invoice, this prompt lists every invoice without a file, names the owner and shows whether approval is completed or who is the current approval step, so you ask the right person. Use it weekly and before the export.

Prompt

Copy the prompt, then replace the highlighted placeholders in your AI assistant.

Invoices Without Attachment: Use Moss MCP
Use AskUserQuestion (clickable multiple choice) to collect [inputs] first. Offer my real entities from Moss as options. Ask me to type names, dates and numbers in chat. If I pick Other, ask again for the exact value.

INPUTS
• Entity: [choose an entity or All entities]
• Date range: [start date] to [end date], or all history
• Stage in Moss: [Review, Export, Exported or all]
• Delivery: [overview in chat & message, or Excel overview only]

RULES
• Look only at the supplier invoices tab in Moss.
• Count an invoice with no PDF as missing its document, drafts included, for the named date range and entity.
• Read the stage from status and export state: Review until completed, Export when completed and not yet exported, Exported when exported.

OUTPUT
• Supplier invoices in the date range without a PDF, rejected ones left out, oldest first: supplier, invoice number, date, gross amount, currency, stage in Moss, transaction ID, owner and either approval completed or the current approval step with who has to approve.
• How many invoices and how much money are missing a document, and who has the most to chase.
• A short message per owner listing their invoices. If every invoice has a file, how many were checked.

How MCP works

MCP is an open standard that lets your LLM look things up in other tools. The Moss MCP gives it read access to your Moss data, so it answers from your real numbers.

01 · Connect

Link Moss to your LLM once

You sign in with your Moss account. After that, your LLM can reach Moss whenever you ask.

02 · Ask

Use a prompt in plain English

Your LLM asks the Moss MCP for what it needs, such as expenses, budgets, bank transactions or receipt files.

03 · Get

An answer from your own data

Lists, summaries and drafts based on what is in Moss. Nothing in Moss is changed.

What MCP can see

You stay in control. The Moss MCP only reads data. It can't change or pay anything.

It can	It can't
Read card transactions and their receipt status	Change, approve or delete anything
Read cardholders, teams and entities	Make payments or move money

FAQ

Yes, for the data. The connector reads your own Moss data, so you need a Moss account.
