Checked on release 3.0.74.2 "Accounting for Kazakhstan" (version 3.0).
The customer calls and says: "Please send a scan of the signed invoice, otherwise the treasury won't process the payment." You have already issued the invoice, and it is in the database. Where to place the signed PDF so that it doesn't linger in the email but is attached specifically to this invoice and can be opened in one click in six months? This is exactly why the directory "InvoiceToCustomerAttachedFiles" exists. This is not a document that you create manually from the menu — it is a "pocket" with the invoice where attachments are stored: a scan with a stamp, an appendix with a breakdown of items, a request letter from the client.
1. Purpose
The service directory stores files attached to the document "Invoice to Customer": scans, PDFs, images, contract appendices. Each record is one attachment with a version history, linked to a specific invoice. The directory does not create its own accounting entries or tax movements — it is about storage and order in documents.
2. Where to find
This directory does not have a separate menu item — and that’s normal, it opens from the "native" document:
- Sales → Invoices to Customers (or Sales → Invoices for Payment to Customers).
- Open the required invoice.
- On the top command panel, click "Attached Files" (the paperclip icon, usually next to a counter — for example, "Attached Files (2)").
- A list of attachments for this invoice will open. Buttons: Add → File from Disk, Create from Template, Scan.
You can open the entire directory at once (all files for all invoices) via a navigation link. Menu "Service" → "Functions for Technical Specialist" or File → "Go to Navigation Link" and paste:
e1cib/list/Directory.InvoiceToCustomerAttachedFiles
This is convenient when you need to view, search, or clean up attachments at once — but in everyday work, access it through the paperclip in the invoice.
2a. How to know your release
Help → About the Program (or the "i" icon in the upper right corner). In the opened window, you will see two lines: platform version (for example, 8.3.24) and configuration release — "Accounting for Kazakhstan, version 3.0 (3.0.74.2)". If the numbers differ from those indicated in the header, some buttons and fields may look different.
3. How to fill
There is not much of a separate "filling form" here — the details of the file card are filled in. Let's break down each field: what it is for and what will happen if you make a mistake.
| Field | Purpose | If filled incorrectly |
|---|---|---|
| Name (mandatory) | How the file will be named in the list. By default, the name of the file from the disk is used. | If you leave "Document (5)" — in a month you won't find the needed scan among a dozen attachments. Write to the point: "Invoice No. 147 signed with a stamp". |
| File (mandatory — the object itself) | The actual data of the attachment, which is stored in the database or on the disk (storage volume). | If you attach the wrong file — the customer will receive someone else's scan. Check the preview before saving. |
| Comment | Note for colleagues: "original with the manager", "version before price correction". | If left blank — not critical, but context is lost. |
| Author | Who attached the file. Automatically set to the current user. | Rarely changes; important for control over who uploaded the document. |
| Date of creation / modification | Automatically filled in, shows the relevance of the version. | Not manually edited — a reference when determining "which version is newer". |
Procedure for attaching a file from disk:
- In the list of attachments, click Add → File from Disk.
- Select the file (PDF, JPG, PNG, XLSX, DOCX — there are practically no restrictions on the type).
- Check Name — rename it clearly.
- Click Save and Close. The file will be added to the database (or to the file storage volume, if it is configured).
Direct scanning: the Scan button launches the connected scanner (a configured scanning utility is needed in Administration → File Handling Settings). Convenient for signed paper invoices.
Editing and versions: double-click → the file opens in an external program. After editing, 1C will suggest save changes as a new version. Old versions are not overwritten — they are visible via the "Stored Versions" button. This is a lifesaver when an edit was made in error.
4. Analyzed Example
You issued Invoice to Customer No. 147 dated 04.09.2026 to LLP "Karavan" for the supply of goods:
- Goods — 100 pcs at 5,000 ₸ = 500,000 ₸ excluding VAT.
- VAT 16% = 80,000 ₸.
- Total to be paid: 580,000 ₸.
The manager printed the invoice, had it signed by the director, stamped it, and scanned it. Your actions:
- Opened invoice No. 147 → Attached Files → Add → File from Disk.
- Selected
Invoice_147_Signature.pdf. - Name: "Invoice No. 147 dated 04.09.2026 — signed, stamp".
- Comment: "Original delivered by courier on 04.09".
- Saved. The invoice now shows "Attached Files (1)" on the paperclip.
Important about entries. The attachment directory does not make any entries — it stores the file. The entries are generated by the movement of goods and money, for which the invoice merely prepares the ground. When you conduct the sale and receive payment for this invoice, the entries will be as follows:
| Operation | Debit | Credit | Amount, ₸ |
|---|---|---|---|
| Sale of goods (income) | 1210 | 6010 | 500,000 |
| VAT 16% accrued | 1210 | 3130 | 80,000 |
| Cost of goods written off | 7010 | 1330 | 380,000 |
| Payment received from customer | 1030 | 1210 | 580,000 |
The scan of the signed invoice remains in the attachments as proof of agreement — it can be opened from the invoice in one click, without retrieving the paper archive.
5. Types of Operations
The attachment directory does not have "types of operations" in the accounting sense. There are ways to work with it:
- File from Disk — attach a ready file.
- Scan — obtain an attachment directly from the scanner.
- Create from Template — generate a document from a pre-established template (for example, a cover letter form).
- By Link (URL) — save a link to an external resource instead of the file itself.
6. What is formed when attaching
- No entries. The accounting register is not affected.
- ESF / VAT invoices are not formed. Electronic invoices are issued from the sales document (ESF in the ESF IS), and VAT invoices are based on the goods transportation chain; the attachment to the invoice has no relation to them.
- A directory record is created with the file body (in the database or in the storage volume) and a record in the version history if the file was edited.
- The attachment counter on the invoice form is updated.
7. Printed Forms
The directory does not have its own printed forms — there is nothing to print except the attachment itself. From the file card, the following are available:
- Open — view in an external program (printing is also available there using the program's tools: Acrobat, image viewer, etc.).
- Save As — export the file back to the disk.
Printed forms (invoice, VAT invoice) relate to the document "Invoice to Customer" itself, not to its attachments.
8. Common Errors
"File is being used by another user" / "Could not obtain file for editing". Someone has already opened the file for editing. Wait for them to close and save the version, or ask them to finish editing. Do not open the same file together.
"File size exceeds the allowable limit". In Administration → File Handling Settings, a limit is set (by default around a hundred MB). Reduce the scan (lower resolution, PDF instead of TIFF) or increase the limit.
"File storage in the information database is not configured" / files are bloating the database. With a large volume of attachments, connect a file storage volume (Administration → File Handling Settings → Storage Volumes). Then the files will be placed on the disk, and the database will remain light.
Attached to someone else's invoice. The attachment is visible on the paperclip of the wrong invoice. Delete the record from the incorrect invoice (Delete) and reattach it from the correct one — there is no "drag and drop" transfer between invoices.
"Changes not saved". You edited the open file but did not confirm saving it as a new version in 1C. When closing the external program, return to 1C and click Finish Editing → save the version.
9. FAQ
Can multiple files be attached to one invoice? Yes, as many as you want. The counter on the paperclip will show their number, and the list will show all attachments for this invoice.
Where are the files physically stored? By default — inside the information database. If storage volumes are configured (Administration → File Handling Settings), the files are on the disk/server, and the database retains a link.
Does the file take up a lot of space — can it be removed from the database? Yes, connect a storage volume and transfer already uploaded files to it. The database will decrease.
How to view the previous version of the edited file? Open the file card → Stored Versions. There you will find a list of all versions with dates and authors; any can be made active.
Who can see and delete attachments? Anyone who has rights to the invoice itself. Rights to view/edit files are regulated by user profiles in the "Administration" section.
Does the attachment generate entries or ESF? No. This is a file storage. Entries are made by sales, and ESF is issued in the ESF IS from the sales document.
Can an attachment be sent to the customer by email directly from 1C? Yes, from the file card or from the invoice via the built-in email sending (if the email account is configured).
What happens to the attachments if the invoice is deleted? Attached files are linked to the invoice. When the invoice is marked for deletion and subsequently cleaned, its attachments will also be deleted — export the necessary ones in advance using the Save As command.
Can a link to a cloud file be attached instead of the file itself? Yes, via Add → By Link (URL). The database will save the address, not the file body.
Is direct scanning supported? Yes, the Scan button works with a TWAIN scanner when the scanning utility is configured.
10. Related Documents
- Parent Object: document "Invoice to Customer" (Sales → Invoices to Customers) — attachments only exist in connection with it.
- Based on the invoice usually enter: Sale of Goods and Services, Receipt to Bank Account (payment), Issued Invoice (ESF).
- Similar attachment directories exist for almost every document: for sales, receipts, contracts — the mechanics of attaching files are the same everywhere.
