Here’s how: * Go to **Purchases** from the left sidebar and click **Bills**. * Select the bill that you want to convert to an invoice. * Click the **Edit** icon in the top right corner of the page. * Select a customer from the **Customer Details** column in the item details table. * You can view if its a non billable item or a billable item under the customer name. Click the option to change it to billable. * Enter a markup percentage if required, and click **Update**. * Save the bill. * Click the **More** option in the top right corner of the details page for the previously edited bill. * Click **Create Invoice**. * The invoice details will be auto-populated. Preview the invoice and make the necessary changes, if any. * Click **Save**.
