Getting Started

Every XtremePlugins product ships as a single .zip file. No build tools, no dependency chains, no mysterious compilation steps. Download it from your account dashboard, upload it to your platform, activate your license key, and you're live.

Before you install anything, double-check that your store meets the platform requirements listed at the bottom of this page. Running an outdated PHP version or an incompatible theme is the number-one cause of post-install headaches, and it takes thirty seconds to verify.

Installation

WooCommerce & WordPress

1. Log in to your WordPress admin panel and go to Plugins > Add New > Upload Plugin.
2. Click Choose File, select the .zip you downloaded, then hit Install Now.
3. Once WordPress finishes extracting, click Activate Plugin.
4. Navigate to the new plugin settings page (usually under WooCommerce > XtremePlugins) and paste your license key. That's it.

Shopify

1. From your Shopify admin, go to Apps and click Manage private apps (or search for XtremePlugins in the Shopify App Store).
2. Follow the on-screen prompts to install the app and grant the requested permissions. We ask for the minimum access necessary—storefront display and order metadata only.
3. After installation, open the app, paste your license key, and configure your settings. Changes go live on your storefront immediately.

Plugin Configuration

Checkout Booster Pro

Open WooCommerce > Checkout Booster (or the Shopify app panel). You'll see three tabs: Trust Badges, Express Checkout, and Cart Recovery. Start with Trust Badges—enable the payment icon strip and the “Secure Checkout” guarantee seal. Those two alone consistently move the conversion needle on stores we've audited.

Express Checkout wires up Apple Pay, Google Pay, and PayPal One Touch to a single floating button. Toggle each provider on or off depending on your gateway setup. Cart Recovery sends a timed email sequence when a shopper abandons; you can customize timing and message copy directly in the editor.

Urgency Countdown

Head to WooCommerce > Urgency Countdown. Pick a trigger: fixed schedule (e.g. “Sale ends Sunday at midnight”) or evergreen per-visitor (starts when the shopper first sees the page). Set the countdown duration, bar color, and position (top bar, inline, or floating). Preview it on desktop and mobile before publishing.

If you combine Urgency Countdown with Checkout Booster Pro's trust badges, you create a one-two punch: urgency drives the click, and trust badges remove the last reason to hesitate.

Sticky Add-to-Cart Pro

Go to WooCommerce > Sticky ATC. Choose between a bottom bar (recommended for mobile) or a slide-in side panel. You can enable variant selection inside the sticky bar so shoppers never have to scroll back up to pick a size or color. Adjust the appear-on-scroll threshold to control exactly when the bar kicks in—200px works well for most product pages, but tweak it if your hero images are taller than average.

Activation & Licensing

Every purchase generates a unique license key tied to your account. You'll find it in two places: the confirmation email and your account dashboard under My Licenses.

• Starter keys activate on one domain at a time. Deactivate the old domain from your dashboard before activating on a new one.
• Pro keys support up to five simultaneous activations—handy for a production site plus staging environments.
• Agency keys have no domain cap. Use them across as many client stores as you need.

If you hit an “activation limit reached” message and you're sure you haven't exceeded your quota, revoke stale activations in the dashboard or contact support for a manual reset. License details and renewal terms are covered in our Terms of Service.

Performance Tips

We obsess over bundle size so you don't have to, but your hosting environment still matters. A few quick wins:

• Enable object caching. Redis or Memcached cuts database queries on every page load. Most managed WordPress hosts offer this as a one-click toggle.
• Serve assets through a CDN. Our plugin scripts are small (under 12 KB gzipped per plugin), but delivering them from an edge node close to your visitors still shaves 50–100ms off load time.
• Audit your other plugins. We regularly see stores running 30+ plugins where half are inactive or redundant. Every extra plugin adds autoload data, cron jobs, and sometimes third-party tracking scripts. Trim the fat.
• Use PHP 8.1 or newer. PHP 8.x runs measurably faster than 7.4 on the same hardware. If your host still defaults to 7.4, upgrading is usually a panel setting, not a migration.
• Lazy-load below-the-fold content. Sticky Add-to-Cart Pro already defers its own scripts until the user scrolls. Make sure your theme and other plugins do the same.
