How to Add a Tip Option to the Wordpress Checkout (2025 Guide)

If you run a service-based business, a restaurant, a local delivery service, or a non-profit using WooCommerce, you are likely facing a specific, frustrating limitation: WooCommerce has no built-in way to accept tips.

In the physical world, the “tipping nudge” is standard. When you buy a coffee, the Square terminal spins around and asks for 15%, 20%, or 25%. When you pay a restaurant bill, the gratitude line is right there on the receipt.

But online? That functionality is missing. And if you are relying on default WooCommerce settings, you are leaving a significant amount of revenue on the table—revenue that belongs to your hardworking staff and delivery drivers.

In this comprehensive guide, we are going to explore exactly how to fix this. We will cover:

The hidden costs of not asking for tips.
Method 1: How to add a tip field using custom PHP code (The “Free” but difficult way).
Method 2: How to use LocalSiteBuilder Tipping to add smart, conversion-optimized tipping buttons in under 2 minutes.
Crucial advice on taxes, accounting, and where to place your tip jar for maximum conversions.

The Economics of the “Digital Tip Jar”

Before we dive into the code, it is important to understand why this feature matters. It isn’t just about “extra money.” It is about adapting to modern consumer psychology.

According to recent studies on digital payments, over 65% of customers are willing to leave a tip if prompted during the checkout process, especially for local services. However, if the customer has to hunt for a “Tip Product” or manually add a donation item to their cart, that percentage drops to near zero.

The friction is the enemy. Every second a customer spends thinking about how to tip is a second they aren’t completing the purchase.

To capture this revenue, the tipping experience must be:

Seamless: No page reloads.
Integrated: Part of the Cart or Checkout flow.
Suggested: Offering “Smart Options” (like 15% or 20%) increases average tip size by over 40% compared to an empty text field.

Method 1: The “Hard Way” (Custom PHP Code)

If you are a developer or comfortable editing your functions.php file, you can hack together a basic tipping solution. This method is free, but it comes with significant maintenance risks.

To do this, we need to hook into the WooCommerce checkout fields and the cart calculation process. We will create a custom field, listen for the input, and then apply a “Fee” to the cart total.

Step 1: Add the Field to Checkout

First, you need to display an input field on the checkout page. You can add this snippet to your child theme’s functions.php file:


/**
 * Add a custom tip field to checkout
 */
add_action( 'woocommerce_review_order_before_payment', 'lsb_custom_checkout_tip_field' );

function lsb_custom_checkout_tip_field() {
    echo '<div id="lsb_tip_checkout_field">';
    woocommerce_form_field( 'lsb_tip_amount', array(
        'type'          => 'text',
        'class'         => array('lsb-tip-field-class form-row-wide'),
        'label'         => __('Would you like to add a tip?'),
        'placeholder'   => __('Enter amount (e.g. 5.00)'),
    ), WC()->session->get('lsb_tip_amount') );
    echo '</div>';
}

Step 2: Calculate and Apply the Fee

Next, you need to capture that value and apply it as a negative fee (which acts as a surcharge) or a standard fee.


/**
 * Add the tip as a fee to the cart
 */
add_action( 'woocommerce_cart_calculate_fees', 'lsb_add_tip_fee_to_cart' );

function lsb_add_tip_fee_to_cart() {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return;

    $tip_amount = WC()->session->get( 'lsb_tip_amount' );

    if ( $tip_amount ) {
        WC()->cart->add_fee( __('Tip', 'woocommerce'), $tip_amount );
    }
}

The Problems with the Code Method

While the code above looks simple, it introduces several critical issues for a live business:

No AJAX Updating: In the code above, if a user types “$5”, nothing happens until the checkout page reloads or updates via a specific trigger. You have to write complex JavaScript (jQuery) to force the WooCommerce checkout fragments to refresh.
Tax Nightmares: By default, WooCommerce “Fees” can be taxable. If you aren’t careful, your store might automatically charge sales tax on the tip. In many jurisdictions (like the US and UK), taxing a gratuity is illegal or creates a massive accounting headache.
No Percentage Logic: The code above only accepts a fixed dollar amount. It cannot calculate “15% of the Subtotal.” To do that, you would need to write a math function that pulls the cart total, excludes shipping/taxes, multiplies by 0.15, and applies the result.
Mobile Unfriendly: A tiny text input field is hard to use on an iPhone. Customers prefer tapping big, friendly buttons (like “$5” or “10%”).

Method 2: The “Easy Way” (Using LocalSiteBuilder Tipping)

For serious business owners who want a “set it and forget it” solution that handles the math, the taxes, and the mobile experience automatically, we built LocalSiteBuilder Tipping.

This plugin replaces the complex code above with a robust, pre-built engine designed specifically for WooCommerce. Here is how to set it up to maximize your revenue.

Step 1: Installation

Once you have downloaded LocalSiteBuilder Tipping from LocalSiteBuilder.com:

Go to your WordPress Dashboard > Plugins > Add New.
Click Upload Plugin and select the ZIP file.
Click Activate.

There is no complex onboarding wizard. We respect your time.

Step 2: Configuring Your “Smart Options”

Navigate to WooCommerce > Settings > LocalSiteBuilder Tipping.

Here, you can define the preset amounts. This is the most important step for conversion optimization. You have two strategies:

The “Delivery” Strategy (Percentages): If you sell food or catering, use percentages. Set your buttons to 10%, 15%, 20%. As the order size grows, so does the tip.
The “Coffee Shop” Strategy (Fixed Amounts): If you have low average order values (e.g., $15), a 10% tip is only $1.50. Instead, set fixed buttons for $2, $3, $5. This subtly encourages a higher tip than the percentage would have yielded.

Pro Tip: Always enable the “Custom Amount” field. Some generous customers (“Whales”) may want to leave a $50 tip on a $100 order. Never block them from doing so!

Step 3: Placement Matters (Cart vs. Checkout)

LocalSiteBuilder Tipping allows you to display the tipping widget on the Cart Page, the Checkout Page, or Both.

Which is better?

Cart Page: This is a “low pressure” environment. Customers are reviewing their items. Placing the tip jar here feels like a polite suggestion. It works well for non-profits or merchandise stores.
Checkout Page: This is the “high conversion” zone. The customer has their credit card in hand. Placing the tip options right above the “Place Order” button mimics the experience of a physical credit card terminal. We recommend this for restaurants and delivery.

Step 4: Handling Taxes (Crucial)

One of the biggest advantages of using LocalSiteBuilder Tipping over custom code is the Tax Handling setting.

In the settings panel, you can choose:

Calculate Tip Before Tax: (Standard) The tip is based on the food/service cost only.
Calculate Tip After Tax: The tip is based on the final Grand Total.
Is the Tip Taxable?: A simple checkbox lets you mark the tip as “Non-Taxable,” ensuring your accounting remains compliant with local labor laws.

Advanced Customization: Matching Your Brand

A tip jar that looks like a scammy pop-up will never convert. Trust is the currency of the checkout page.

LocalSiteBuilder Tipping automatically inherits your theme’s fonts and button styles (whether you use Astra, Divi, Flatsome, or Elementor). However, you can further customize the labels to match your brand voice.

Don’t use boring labels. Be creative:

Standard: “Add a tip.”
Friendly: “Buy the team a coffee?”
Mission-Driven: “Support our local drivers.”
Playful: “Feed the developers.”

You can change all these text strings directly inside the plugin settings without writing a single line of CSS.

Frequently Asked Questions

Does this work with Payment Gateways like Stripe or PayPal?

Yes. Because LocalSiteBuilder Tipping adds the tip as a standard WooCommerce “Fee” line item, it is passed to the payment gateway just like shipping or taxes. It works perfectly with Stripe, PayPal, Square, Authorize.net, and Apple Pay.

What about Reporting?

At the end of the month, you need to know how much to pay your staff. If you used the manual code method, you’d have to use a calculator and go through every order manually.

With LocalSiteBuilder Tipping, the tip amount is stored in a separate data column. You can see the total tips collected in your WooCommerce Reports or export your orders to CSV to sum up the “Tip” column in Excel.

Will it slow down my site?

No. We hate bloated plugins as much as you do. LocalSiteBuilder Tipping only loads its assets (CSS/JS) on the Cart and Checkout pages. It will not slow down your homepage, product pages, or blog posts. It is optimized for Core Web Vitals.

Conclusion

Adding a tip option to your WooCommerce store is a rare “win-win-win” scenario:

Your Staff Wins: They earn extra income for their hard work.
Your Customers Win: They get to express gratitude and feel good about supporting a local business.
You Win: You retain happier employees and modernize your checkout experience.

You can try to hack it together with PHP snippets, but the risk of tax errors and broken checkout flows is high. For the price of a few cups of coffee, LocalSiteBuilder Tipping solves the problem professionally, legally, and beautifully.
