# Invoices

The list and its filters, sending a new invoice, the document detail, and what can still be cancelled.

The **Invoices** section holds both outbound and inbound documents in one
place.

### The list

The table shows UUID, direction, document type, status, sender, recipient,
MLS status and date.

You can search by invoice number, supplier or customer (from two characters
up). Filters cover status, direction, a date range and an amount range. The
result can be exported to CSV.

### Sending a new invoice

There are two ways to send an invoice from the portal:

- **+ New invoice** opens a form where you fill in the invoice without an
  accounting system and without XML. The button is shown to the Admin and
  Operator roles — see [Issuing an invoice in the
  portal](/help/en/portal/vystavenie-faktury/).
- **Upload XML** is for a ready-made invoice from your accounting system.
  You enter the sender and recipient Peppol IDs and paste the invoice UBL
  XML. After submission the portal shows the validation results — for each
  finding the rule, its severity, the message and the location in the
  document (XPath).

If your accounting or ERP system produces the invoices, you do not have to
paste them by hand — connect it through the API. The procedure is in the
[integration guide](/developers/en/).

### Document detail

The detail has four tabs:

- **Overview** — direction, sender, recipient, dates.
- **PDF preview** — generated on demand and downloadable.
- **Validation** — the document check results.
- **History** — the processing trail.

For outbound documents you also see the **MLS status** (C3 = receiving
Access Point, C5 = the tax authority) and the **TDD status** (submit,
resubmit, disregard).

### Actions

Download XML, download PDF and — for inbound documents — confirm receipt.

**Only an invoice in the Pending or Validating state can be cancelled.** Cancelling
releases the credit it had reserved. The action cannot be undone. Once a
document leaves for the network it cannot be withdrawn — corrections go
through a credit note, see [What an e-invoice is — and is
not](/help/en/povinnosti/co-je-efaktura/).

### Document statuses

The meaning of each status and the transitions between them are documented in
one place in the integration guide: [Invoice statuses](/developers/en/stavy/).
That page is compared against the system's real status list at build time, so
it cannot drift from reality.

For orientation it is enough to know that a document moves from acceptance by
the system through validation to dispatch. Once the recipient's access point
takes it over, its status is **Received by recipient's access point**. Delivery
is confirmed only by that access point's delivery confirmation (MLS) — the
status then becomes **Delivered**, or **Rejected** if the recipient's access
point refused it. Neither says whether the buyer approved the invoice
commercially.
