Documents and payments
Documents lists the available PDF, UBL and attachment files. Download saves a file. Upload document or dragging into the box adds attachments, up to 5 MB per file. Only files of type Attachment can be deleted here. Uploading and deleting an attachment take effect immediately; they do not wait for Save on the page.
Payments shows the payment method, date, amount and any note for each entry. Total paid adds up these entries. This card is for checking; you do not make a payment here.
System information
System shows when the entry was created and last changed. These details are read-only.
Save and confirm
After a change, use Save; Cancel restores the saved data. On a saved page, View PDF opens the document.
Process a draft with Confirm purchase invoice. It then receives the payment status matching the total and recorded payments: open, partially paid or paid. Later changes to amounts can also change the payment status.
Options and consequences
| Action | Effect |
|---|---|
| Convert to purchase credit note | Corrects an incorrect document type. This is only possible for a draft without linked receipt, stock or depreciation data. The invoice is replaced by a draft credit note; files and payment entries move with it. |
| Convert to goods receipt | Creates a separate draft receipt based on linked product lines. The invoice must contain at least one suitable product line. The invoice remains; the receipt still needs processing to record stock. |
| Mark as exported | Records that you have already processed the document outside this export process. It sends nothing to your accountant. The option disappears when the document is marked as exported. |
Important: converting to another purchase document type replaces the original draft. Check the desired type before confirming the conversion; files and payment entries move with it.
Delete
Delete is available for a draft and asks for double confirmation.
Important: deletion is permanent and also removes the associated files and payment entries. Check whether you want to retain the document and its processing.
