Billing – Issuer, Customer & Documents Tabs
These three tabs complete the administrative and compliance information required for issuing a billing document.
They define who is issuing the billing, who is receiving it, and which documents are attached for audit or client reference.
This article explains the purpose of each tab, the fields available, and how they contribute to the billing lifecycle.
Access Path
Operations Management → Billing
1. Issuer Tab
The Issuer tab identifies which company or branch is officially issuing the billing document.
This information is pulled from System → Companies Setup and ensures legal compliance for invoicing.
1.1 Purpose
- Defines the legal entity responsible for the invoice
- Ensures correct fiscal identification on billing documents
- Populates mandatory fields such as tax number, address
- Supports multi-company environments
- Determines operational settings such as:
- Default currency
- Default tax configuration
- Working calendar
- Default bank information
1.2 Main Fields

| Field | Description |
|---|---|
| Company | Selects the company issuing the billing. Required. |
| Company Name | Company issuing Name |
| Company Address | Legal billing address of the issuer. |
| Tax Number / VAT ID | Automatically filled from company settings. |
💡 All issuer information is locked or auto-populated based on company setup, ensuring consistency and legal validity.
2. Customer Tab
The Customer tab defines who will receive the invoice.
Customer information is retrieved from the Sales Management – Contact entity.
2.1 Purpose
- Identifies the client being billed
- Pulls customer master data directly from Contact records
- Ensures proper fiscal identification for invoicing
- Simplifies recurring billing for existing clients
2.2 Main Fields

| Field | Description |
|---|---|
| Person | The individual associated with the billing process (e.g., requester, project contact). This is typically used when the billing relates to a specific person rather than a general company entity. |
| Company | The customer’s company or organization. This field identifies the legal entity to which the billing belongs. |
| Account | The customer account within Uneevo. This represents the customer to be billed — the entity receiving the invoice. |
| Contact | The designated contact person inside the customer’s organization responsible for receiving or approving billing documents. |
| Name | The full legal or commercial name of the customer being billed. Often auto-filled from the selected account or contact. |
| Address | The billing address of the customer, used for invoice issuance and compliance purposes. |
| Tax Number | The customer’s tax identification number (VAT, NIF, EIN, etc.). Required for fiscal and reporting compliance. |
💡 If the customer record is incomplete (missing VAT, missing address…), the system warns the user to complete the information before issuing the billing.
3. Documents Tab
The Documents tab allows users to upload, preview, and manage files related to the billing.

These may include:
- Signed contracts
- Purchase orders
- Timesheet reports
- Travel documents
- Proof of delivery
- Any compliance or audit files
3.1 Purpose
- Centralizes all evidence related to the invoice
- Provides auditors and managers with full traceability
- Ensures customer support teams can quickly find attached documents
- Supports digital audit trails for billing validation
3.2 Key Actions

| Action | Description |
|---|---|
| Add Document | Upload files (PDF, images, spreadsheets, etc.). |
| View / Preview | Open the document inside the system. |
| Download | Save a copy locally. |
| Delete | Remove documents (only possible while billing is in editable status). |
💡 Once the billing has submitted, the addition of documents becomes restricted
4. Lifecycle Considerations
| Billing Status | Issuer Editable? | Customer Editable? | Documents Editable? |
|---|---|---|---|
| Draft | ✔ Yes | ✔ Yes | ✔ Yes |
| Submitted | ✔ No | ✔ No | ✔ No |
| Validated | ✔ No | ✔ No | ✔ No |
| Issued | ✔ No | ✔ No | ✔ No |
| Closed | ✔ No | ✔ No | ✔ No |
5. Best Practices
✔ Complete customer and issuer information before adding items
Fewer errors and smoother approval.
✔ Upload proof-of-work documents
Timesheets, allocation reports, or travel receipts help ensure billing disputes are avoided.
✔ Configure the company correctly
The Issuer tab relies on system-level configuration — ensure tax IDs, addresses, and bank details are correct.
✔ Keep attachments organized
Use descriptive file names such as PO_45_ClientA.pdf or Timesheet_March2025.xlsx.
