List invoices

fieldtask_list_invoices

Read-only

Permissions: customers:read, invoices:read
REST equivalent: GET /public/v1/invoices
Safe retries: Reads only; safe to repeat

fieldtask_list_invoices lets an AI client list the invoices in your organization, page by page, with their totals, paid amounts and balances. It's how the client answers questions such as "which invoices are unpaid?" and finds an invoice before reading its items with fieldtask_get_invoice.

Listing invoices never changes them. No FieldTask tool sends an invoice, records a payment or collects money.

Same checks and results as REST GET /public/v1/invoices.

Permissions

Permissions the connection must hold for the tool to appear and run.
Permission	Dependency in the permission map
`customers:read`	No dependencies
`invoices:read`	Depends on `customers:read`

The tool is offered only when invoicing is enabled for your organization.

Example prompts

You ask	What the client typically does
"Which invoices are still unpaid?"	Calls the tool with `status: "unpaid"`, which covers sent and partly paid invoices, and follows the pages.
"Show unpaid October invoices for Example Property Services, with their balances."	Finds the customer with `fieldtask_list_customers`, then calls this tool with `customer_id`, `status: "unpaid"`, `issued_from: "2026-10-01"` and `issued_to: "2026-10-31"`.
"List this month's draft invoices."	Calls it with `status: "draft"` and an `issued_from`/`issued_to` range.

Arguments

All arguments are optional and can be combined.

status filters on the stored status. unpaid means sent or partial; it excludes drafts, paid and void invoices.
issued_from and issued_to are inclusive issue dates in YYYY-MM-DD format, not due dates or creation dates. issued_from can't be later than issued_to.
customer_id must be a customer in your organization; otherwise the call fails with resource_not_found.

Arguments for fieldtask_list_invoices. Descriptions are the text your AI client receives.

cursorstringoptional
1–4096 characters
customer_idstring (uuid)optional
issued_fromstring (date)optional
Inclusive invoice issue date, not due/creation date.
issued_tostring (date)optional
Inclusive invoice issue date.
ordering"created_at" | "-created_at"optionaldefault "created_at"
Oldest first (created_at) or newest first (-created_at). Keep unchanged when following a cursor.
page_sizeintegeroptionaldefault 25
status"draft" | "sent" | "paid" | "partial" | "void" | "unpaid"optional
unpaid means sent or partial; excludes draft, paid and void.

Additional properties are rejected.

To read the next page, the client passes page.next_cursor back as cursor, keeping the other arguments unchanged. A page can hold fewer invoices than page_size so that it fits in an MCP response; page.has_more is still true when more remain.

Result

The result has data, a list of invoices, and page. Each invoice has its number, status, customer, dates and amounts, but not its items, taxes or discount. Those come from fieldtask_get_invoice.

Amounts are decimal strings in currency:

total_amount is the total including tax, before the invoice discount.
discounted_amount is the final invoice total.
paid_amount is the sum of payments recorded in FieldTask.
balance is discounted_amount minus paid_amount, and can be negative.

See the field descriptions for the rest.
