How to track supplier invoices with a Dust agent
With the Spendesk MCP connected to a Dust agent, tracking the invoice payment lifecycle becomes conversational — in Dust's chat or right inside Slack. Here's how AP teams use this approach every day.
The problem
Tracking supplier invoices is one of the most time-consuming tasks for AP teams. Between Spendesk, email follow-ups, and ERP exports, you have to juggle multiple tools just to answer a simple question: "Where does the Doctolib invoice stand?"
What changes with a Dust agent connected to the Spendesk MCP
Once the workspace admin has connected the Spendesk MCP, a Dust agent configured with the Invoice payment lifecycle tracker skill can be queried directly in Dust's chat, or mentioned with @Dust right where the AP team already talks — in Slack.
"Show me all approved invoices that haven't been paid yet, sorted by amount descending"
The agent automatically calls get_payables with the right filters and returns a readable table in seconds.
4 everyday use cases
1. Global payment pipeline overview
For a quick morning check-in, in Dust's chat or by mentioning @Dust in the AP channel:
"Give me the state of the payment pipeline: how many invoices pending, how many scheduled, how many settled this month?"
2. Status of a specific invoice
To respond to a supplier following up, without even leaving Slack:
"@Dust where does the Stripe invoice from June 15 stand?"
The agent searches by supplier name and returns the precise status: approved, scheduled (with date), exported, settled.
3. Daily cash flow delta mode
Particularly useful for CFOs who want to anticipate cash outflows:
"What payments are scheduled for the next 7 days? What is the impact on my cash flow?"
4. Pre-export verification
Before exporting to the accounting system:
"List all invoices in 'exported' status that don't have a settlement yet — is that normal?"
A published agent, not a personal tool
Unlike an install that stays tied to one workstation, a Dust agent configured once with the Spendesk MCP tools can be published for the whole AP team. Every member can query it with their own questions, in Dust's chat or by mentioning it in Slack — no reinstall, no individual setup.
A limitation to know
The Spendesk MCP provides access to invoices from the 'approved' stage onward. Invoices still in validation (inbox, review, pending_approval) are not visible. This is a documented limitation of the MCP server itself — it applies identically no matter which platform is used to query the agent, and is scheduled to be lifted in Q3 2026.
