# Installing WCPOS Pro
Pro Feature
[WCPOS Pro](https://wcpos.com/pro) is a paid plugin that powers the management screens, additional payment gateways, and other Pro-only features in WCPOS.
**As of v1.8+, Pro is a standalone plugin** — you do not need the free [WCPOS plugin](https://wordpress.org/plugins/woocommerce-pos/) installed alongside it.
## What's Included in Pro?[](#whats-included-in-pro "Direct link to What's Included in Pro?")
WCPOS Pro unlocks additional features:
* **Products Screen** - Edit stock levels and prices directly in the POS
* **Orders Screen** - View and manage order history
* **Customers Screen** - Add and edit customer information
* **Reports Screen** - Generate end-of-day sales reports
* **Additional Payment Gateways** - Stripe Terminal, SumUp, and custom gateways
## Installation[](#installation "Direct link to Installation")
If you have purchased a license for WCPOS Pro please follow the steps below to install and activate the plugin:
Upgrading from older versions?
If you previously had both the free WCPOS plugin and an older Pro add-on installed, **deactivate and delete the free plugin** before activating the new standalone Pro plugin. Running both side-by-side can cause activation errors such as *"Invalid response fetching remote state"* or fatal *"Class not found"* errors.
1. Go to:
2. Under **Downloads**, click the download link and save the plugin to your desktop.
3. Then go to your site, login and go to `WP Admin > Plugins > Add Plugin > Upload Plugin`
4. Upload the plugin zip file from your desktop and activate.
5. Next, go to `WP Admin > POS > Settings > License` and enter your License Key and License Email to complete the activation.
## Updates[](#updates "Direct link to Updates")
When new versions are ready they will appear in your Updates dashboard like any other plugin. You can also download the latest version from your [account page](https://wcpos.com/my-account/).
## Troubleshooting[](#troubleshooting "Direct link to Troubleshooting")
### Activation Failures[](#activation-failures "Direct link to Activation Failures")
* **"Invalid licence key"** — double-check for trailing spaces when pasting, and confirm the email address matches the one used at purchase.
* **"Licence limit reached"** — by default a licence activates on **2 domains** (intended for one live site and one staging site). Note that **subdomains count as separate activations** — `example.com`, `staging.example.com`, and `dev.example.com` are three. This often catches hosts like Pantheon with mandatory dev/test/live environments. Deactivate unused sites from your [account page](https://wcpos.com/my-account/), or email **** — extra activations are routinely granted on request.
### Expired Licence[](#expired-licence "Direct link to Expired Licence")
* When a licence expires, Pro features remain active but you won't receive updates.
* Renew from your [account page](https://wcpos.com/my-account/) — the existing key stays the same.
### Domain Transfers[](#domain-transfers "Direct link to Domain Transfers")
* If you've moved your site to a new domain, deactivate the licence on the old domain first, then reactivate on the new one.
* If the old domain is no longer accessible, contact **** to reset the activation.
### Licence Server Connectivity[](#licence-server-connectivity "Direct link to Licence Server Connectivity")
* Activation requires your WordPress server to reach the WCPOS licence server.
* If activation fails silently, check that outbound HTTPS requests aren't blocked by your host's firewall or a security plugin.
* Some managed hosts block external API calls by default — contact your host to whitelist `wcpos.com`.
### Checking Licence Status[](#checking-licence-status "Direct link to Checking Licence Status")
* Go to `WP Admin > POS > Settings > License` to see your current activation status.
* Your [account page](https://wcpos.com/my-account/) shows all active sites and expiry date.
