# Add a Bill
Adding a bill is similar to adding an expense. However, when adding a bill, you can also include Retainage, the percentage of the payment withheld until the project is fully or substantially completed.
To add a bill:
1. Go to **Account Payable > Bill**.
2. Select **+ New Bill > Bill.**
3. In **Essentials**, fill in the necessary information:
* **Vendor:** The company or individual you are receiving the bill from.
* **Job (optional):** Assign the bill to a job if it relates to a specific project to help track job costs accurately.
* **Transaction Date:** The date the bill was issued.
* **Posting Period:** The financial period in which the bill should be recorded.
* **No.:** The bill or reference number for tracking and documentation.
4\. (Optional) You can also select **+ Add Item** to add new items. This section allows you to specify the details of each item or service associated with the expense:
* **Account:** Choose the correct account category (e.g., materials, subcontractor cost, equipment).
* **Description:** A short explanation of the item or service being billed.
* **Cost Code:** Select the correct cost code to ensure accurate job costing.
* **Amount:** Enter the dollar amount for each item.
* **Billable:** Mark whether this cost can be billed to a customer.
* **Delete (under Actions):** Remove any item added by mistake before saving the bill.
5. (Optional) In **Lien Waivers,** you can upload a supporting document, such as a PDF, image file (JPG/PNG), or scanned copy of the waiver. You can also select the appropriate waiver type:
* **Unconditional Progress:** Used when the vendor has already been paid for a portion of the work and gives up their right to file a lien for that payment immediately.
* **Conditional Progress:** Used when payment is expected but not yet received. The waiver becomes effective only when the payment clears.
* **Conditional Final:** Used when the vendor expects final payment for the full scope of work. The waiver becomes effective once final payment is received.
* **Final:** Used after the vendor has received full and final payment. This permanently waives their right to file a lien for the completed work.
* **Other:** Any additional document that may apply outside the standard categories.
5. Select **Save** to complete the process. Your bill will now appear in the Accounts Payable list, ready for approval, payment, or further review.
6. (Optional): Go to the **Paid** tab to see your created bill.
With your bill recorded and retainage applied, you are set to manage vendor payments more accurately and keep your job costs on track.
