# IEbillInvoiceQueryProvider

Contract implemented by `EbillInvoiceQueryProvider`.

## Purpose
- Defines the members that `EbillInvoiceQueryProvider` must provide to callers of this abstraction.

## Context
- Namespace: `SAIF.Data.Queries.Claims.Ebilling`
- Assembly/package: `SAIF.Data`

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| GetInvoice | `EbillInvoice GetInvoice(DateTime invoiceMonth)` | Retrieves invoice.* |
| GetInvoiceBills | `IEnumerable<EbillInvoiceBill> GetInvoiceBills(EbillInvoice invoice)` | Retrieves invoice bills.* |
| GetInvoiceError | `IEnumerable<EbillInvoiceError> GetInvoiceError(EbillInvoice invoice)` | Retrieves invoice error.* |

## Behavioral notes
- As an interface, this type defines no executable behavior of its own; behavior is determined by its implementation(s).*

## Constraints and usage notes
- Callers should depend on this interface rather than the concrete implementation(s) (`EbillInvoiceQueryProvider`) to preserve testability.*

> **Note:** Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
