PW Merchant is developed to help WooCommerce store owners review product data, connect their store with Google Merchant Center and manage supported Merchant operations through a more structured workflow.
A successful installation is not limited to uploading and activating the plugin. The WooCommerce store, WordPress environment, licence status, Google account and Merchant Center configuration should also be prepared correctly.
This guide explains the recommended installation process from the first system check to the first controlled product operation.
Following these steps in order helps reduce connection problems, duplicate product sources, licence errors and catalogue issues.
Check the system requirements first
Before installing PW Merchant, confirm that the website meets the required technical conditions.
The store should have an active and properly maintained WordPress installation. WooCommerce must already be installed, activated and functioning correctly.
The server environment should also be suitable for product reviews, API communication and background operations.
Check the following areas before continuing:
WordPress is installed and working correctly.
WooCommerce is active.
PHP meets the supported minimum version.
The website uses HTTPS.
WordPress REST API access is not blocked.
Scheduled WordPress tasks can run.
The server has sufficient memory and processing resources.
The database is functioning correctly.
The administrator account has permission to install plugins.
The website is not in maintenance mode.
An old or unstable WordPress environment can create problems during installation and later Merchant operations.
Before installing a commercial plugin, create a current backup of the website files and database.
A reliable installation begins with a healthy WordPress and WooCommerce environment.
Review the WooCommerce store before installation
PW Merchant works with product information already stored in WooCommerce.
For this reason, the condition of the WooCommerce catalogue directly affects the Merchant workflow.
Before installing the plugin, review whether products contain basic and usable information.
Brand and identifier information is available where relevant.
The plugin can help identify missing or problematic fields after installation, but beginning with a well-maintained catalogue creates a more efficient setup process.
Use the original PW Merchant package
Install PW Merchant only from an authorised distribution source.
An original plugin package provides a more reliable foundation for licence verification, updates, compatibility and support.
Modified or unofficial packages may contain unknown code changes, incomplete files, removed security controls or outdated components.
Before uploading the plugin, confirm that:
The ZIP file came from an authorised PW Feed source.
The file name and version match the expected package.
The ZIP archive has not been manually altered.
The package is intended for the correct website.
The licence information is available.
The original package should be stored safely so that it can be used again if a controlled reinstallation becomes necessary.
Create a full website backup
Installing PW Merchant should not normally affect existing products or orders, but creating a backup before any important plugin installation is good practice.
The backup should include:
WordPress files
The active theme
Installed plugins
Uploaded media
The WooCommerce database
Product information
Order records
Website settings
Make sure the backup is complete and accessible.
A backup that has never been tested or cannot be downloaded may not provide sufficient protection during an emergency.
Upload PW Merchant through WordPress
PW Merchant can normally be installed through the WordPress administration panel.
Use an administrator account and open the plugin installation area.
The standard process is:
Sign in to WordPress administration.
Open the Plugins section.
Select Add new plugin.
Select Upload plugin.
Choose the authorised PW Merchant ZIP file.
Start the installation.
Wait until WordPress confirms that the package has been installed.
Do not extract the ZIP file before using the WordPress upload screen unless the provided installation instructions specifically require a manual FTP process.
If WordPress reports that the destination folder already exists, an older version of the plugin may still be present.
Do not delete the folder immediately without checking whether the existing installation contains active settings or belongs to the current working version.
Install PW Merchant through FTP when necessary
If the WordPress upload process fails because of server limits, the plugin can be installed through FTP or the hosting file manager.
For a manual installation:
Extract the authorised ZIP package on your computer.
Confirm that the extracted folder contains the main plugin files.
Connect to the website through FTP or the hosting file manager.
Open the WordPress wp-content/plugins directory.
Upload the complete plugin folder.
Return to the WordPress Plugins screen.
Find PW Merchant in the installed plugin list.
The plugin folder name should remain unchanged unless the official package instructions state otherwise.
Changing the folder name can affect updates, internal paths and compatibility checks.
Activate the plugin
After installation, activate PW Merchant from the WordPress Plugins screen.
During activation, the plugin may check the WordPress version, WooCommerce status, PHP version and required system conditions.
If activation is blocked, read the displayed message carefully.
Common activation problems may include:
WooCommerce is not active.
The PHP version is unsupported.
The WordPress version is too old.
A required PHP extension is unavailable.
The plugin files are incomplete.
An older conflicting version is still installed.
A server security rule blocks the activation request.
Do not repeatedly activate the plugin without correcting the underlying problem.
If WordPress shows a fatal error, record the message and check the server error log before making further changes.
Confirm the WooCommerce connection
After activation, PW Merchant should recognise the active WooCommerce environment.
Open the plugin administration area and review the system status.
Confirm that:
WooCommerce is detected.
Products can be counted or accessed.
The store currency is recognised.
The WordPress site address is correct.
The active domain matches the expected installation.
No critical compatibility warning is displayed.
If the plugin cannot access WooCommerce products, check whether another security plugin, custom code or database issue is blocking the required queries.
Complete the licence verification
PW Merchant uses a controlled licensing structure to support authorised use, original software distribution, updates and continued support.
Open the licence area inside the plugin and enter the required licence information.
The exact screen may vary according to the installed version, but the process normally includes:
Entering the licence key
Confirming the authorised domain
Starting the verification request
Reviewing the licence status
Checking the remaining licence period
The domain should normally match the website where PW Merchant is installed.
Using the same licence on an unauthorised second website may cause verification problems.
Enter the domain consistently. Avoid unnecessary differences such as incorrect protocols, extra paths or unrelated subdomains.
Licence verification helps confirm that the original PW Merchant package is being used on the authorised website.
What to check when licence verification fails
A failed licence request does not always mean that the licence is invalid.
The problem may be related to the website, server or connection environment.
Review the following conditions:
The licence key was entered correctly.
No extra spaces were copied with the key.
The licence is active.
The licence belongs to the correct product.
The authorised domain matches the current website.
The website can make external HTTPS requests.
The server firewall does not block the verification service.
The system clock is correct.
A security plugin is not blocking the request.
The licence has not already reached its installation limit.
Do not share the licence key publicly or include it in screenshots sent through unsecured channels.
Review the PW Merchant system status
After activation and licence verification, review the plugin system status before connecting Google Merchant Center.
A system status area may help confirm:
WordPress compatibility
WooCommerce compatibility
PHP compatibility
Licence status
API communication availability
Scheduled task status
Database readiness
Required permissions
Resolve critical system warnings before beginning a large product review.
Warnings about server performance or scheduled tasks should also be evaluated carefully, especially for stores with large catalogues.
Prepare the Google Merchant Center account
PW Merchant requires a properly prepared Google Merchant Center environment.
Before connecting, make sure that:
The correct Google account is available.
The Merchant Center account exists.
The business information is complete.
The website is verified and claimed.
Shipping settings are prepared.
The return policy is entered.
The website contains visible contact information.
Product pages are publicly accessible.
Existing product data sources have been reviewed.
Do not connect a Merchant account that belongs to another business or an unrelated website.
Review existing Merchant data sources
Before starting the API connection, inspect the product data sources already present in Merchant Center.
An older XML feed, automatic website source, platform connection or previous plugin may already be sending products.
Record the following information:
Source name
Source type
Products managed by the source
Update frequency
Product identifiers
Current source status
Do not leave an old source and the new PW Merchant source managing the same products without a clear plan.
This can create duplicate products, conflicting stock information or different price values.
Connect the correct Google account
Open the Google connection section inside PW Merchant and begin the supported authorisation process.
Before continuing, sign out of unrelated Google accounts or confirm that the correct account is selected.
During the authorisation process:
Review the Google account name.
Confirm the email address.
Read the requested permissions.
Select the correct Merchant Center account.
Complete the connection.
Return to the PW Merchant administration screen.
After connection, review the displayed account information.
Do not start product operations if the wrong Merchant account or business is shown.
Confirm the Merchant Center account selection
Businesses, agencies and administrators may have access to more than one Merchant Center account.
Selecting the wrong account can send products to an unrelated environment.
Confirm:
Merchant account name
Merchant account identifier
Connected business name
Website domain
Target country
Product language
The selected Merchant account should represent the WooCommerce store where PW Merchant is installed.
Configure the main plugin settings
After the Google connection is complete, review the main PW Merchant settings.
The exact options depend on the installed version, but important areas may include:
Merchant account selection
Target country
Product language
Store currency
Product review preferences
Batch size
Scheduling settings
Logging preferences
Notification settings
Use conservative settings for the first installation.
Do not select the largest batch size or begin full-catalogue operations before testing the server and connection.
Run the first product review
The first major action should be a catalogue review.
Do not begin by sending the entire WooCommerce catalogue.
The review helps identify:
Suitable products
Problematic products
Critical products
Products without images
Products without valid prices
Stock issues
Incomplete product information
Variation problems
The first review also helps confirm that PW Merchant can read the catalogue correctly.
For a large store, begin with a smaller category or limited product group where possible.
Review critical products first
Critical products should normally be handled before other groups.
A critical issue may involve missing essential information, an inaccessible product page, unavailable pricing or another condition that can prevent meaningful processing.
Open the affected WooCommerce product and review the field identified by PW Merchant.
After correcting the issue:
Save the WooCommerce product.
Clear relevant cache if necessary.
Run the product review again.
Confirm whether the critical status has changed.
Do not send known critical products simply to test whether Google will accept them.
Review problematic products
Problematic products may contain incomplete or inconsistent information that should be checked before the next operation.
Examples may include:
Short descriptions
Missing brand information
Incomplete variation details
Possible image issues
Questionable identifier data
Price or stock inconsistencies
Not every warning will prevent processing, but correcting relevant issues can improve catalogue quality and reduce repeated work.
Select a limited test group
After reviewing the catalogue, choose a small and representative group for the first supported Merchant operation.
A useful test group may contain:
One simple product
One variable product
One product with a sale price
One product with stock management
One product with complete brand and identifier data
This allows you to compare different WooCommerce product structures without placing unnecessary pressure on the server.
The first operation should confirm the workflow, not process the entire catalogue.
Start the first controlled operation
Begin the test operation from the relevant PW Merchant screen.
Monitor the process and wait for the operation to complete.
Review:
Products selected
Products completed
Successful operations
Warnings
Failed items
External Merchant responses
Do not repeat a failed operation immediately without reading the available issue information.
Correct the relevant WooCommerce data or connection problem first.
Check the products in Merchant Center
After the test operation, open Google Merchant Center and review the relevant product source and products.
Check whether:
The products appear in the expected account.
The product identifiers are correct.
Prices match WooCommerce.
Stock information matches the website.
Product images are accessible.
Product links open correctly.
Duplicate records have appeared.
Warnings or processing issues are displayed.
External processing may require additional time. Do not assume that a product has failed only because it does not appear immediately.
Prevent duplicate product sources
After confirming that the PW Merchant test works, review the older Merchant sources again.
If the old XML feed and PW Merchant manage the same products, decide which source should remain responsible.
A safe transition process may include:
Compare the old and new product identifiers.
Confirm that the API products are processed correctly.
Check for duplicate records.
Pause the old source where appropriate.
Observe the Merchant account after the change.
Remove the old source only after successful verification.
Do not delete a source without understanding which products depend on it.
Configure scheduled operations carefully
Large catalogue operations may be more suitable during quieter periods.
PW Merchant can support planned operations according to the available scheduling features.
When configuring a schedule:
Select a low-traffic time.
Avoid overlapping with backups.
Avoid overlapping with large imports.
Do not run several demanding tasks at the same time.
Confirm that WordPress scheduled tasks work reliably.
Review the results after the first scheduled run.
A night-time operation may be practical for a large store, but the server should still be monitored.
Monitor background and batch processing
PW Merchant may divide large tasks into smaller groups to improve stability.
Monitor the first batch operations carefully.
Check whether:
The number of completed products increases.
Tasks continue after leaving the administration page.
No repeated timeout occurs.
The database does not grow unexpectedly.
The website remains responsive.
Scheduled tasks continue to run.
If processing stops repeatedly, reduce the workload and check the server environment.
Possible causes may include low memory, PHP execution limits, database problems, external API delays or conflicts with another plugin.
Review logs without exposing sensitive data
Operation records can help identify installation and connection problems.
However, logs should be managed carefully.
Do not publish logs that contain:
Licence keys
Access tokens
Customer information
Administrator credentials
Private server paths
Security secrets
When requesting support, provide only the information required to understand the issue.
Common installation mistakes
Many PW Merchant installation problems are caused by incomplete preparation rather than the plugin itself.
Common mistakes include:
Installing the plugin before WooCommerce
Using an unsupported PHP version
Uploading an incomplete ZIP package
Changing the plugin folder name
Using the wrong licence key
Connecting the wrong Google account
Selecting the wrong Merchant Center account
Ignoring an existing XML feed
Starting with the full catalogue
Processing critical products without correction
Running large operations during peak traffic
Ignoring WordPress scheduled task problems
Using a low-resource hosting environment
Following a controlled installation order helps prevent these conditions.
Updating PW Merchant
PW Merchant should be updated only through an authorised source.
Before applying an important update:
Create a current backup.
Review the version notes.
Confirm WordPress and WooCommerce compatibility.
Check the licence status.
Complete or pause active operations.
Avoid updating during a large background process.
After updating, review the plugin system status and confirm that the Google connection, licence and scheduled operations remain active.
Reinstalling PW Merchant
Reinstallation may be required if plugin files are damaged or an update is interrupted.
Do not remove the plugin without first reviewing whether the uninstall process deletes settings or operational records.
A controlled reinstallation should include:
Create a full backup.
Record current plugin settings.
Confirm the licence key is available.
Complete or stop active tasks.
Remove only the damaged plugin files.
Upload the original package again.
Activate the plugin.
Confirm licence and connection status.
Run a limited product review.
Do not manually delete database tables unless official support specifically instructs you to do so.
Uninstalling the plugin
Before uninstalling PW Merchant, consider what will happen to active operations, stored settings and the Merchant data source.
Removing the WordPress plugin does not automatically remove products or sources from Google Merchant Center.
Before uninstalling:
Stop scheduled operations.
Review the Merchant source.
Record the current settings.
Create a full backup.
Confirm whether the licence should be released.
Decide which product source will remain active.
After removal, review Merchant Center to ensure that the remaining product-source strategy is still correct.
Installation support
If a problem cannot be resolved through the available status information, use the official support channel.
Before moving from installation to regular use, confirm the following:
WordPress is working correctly.
WooCommerce is active.
The supported PHP version is installed.
The website uses HTTPS.
A full backup exists.
The original PW Merchant package is installed.
The plugin is active.
The licence is verified.
The correct domain is authorised.
The correct Google account is connected.
The correct Merchant Center account is selected.
Existing data sources have been reviewed.
The first product review has completed.
Critical products have been checked.
A limited test group has been processed.
Products have been reviewed in Merchant Center.
No unintended duplicate source exists.
Scheduled operations are configured carefully.
Support and update access are available.
PW Merchant installation is complete when the plugin, licence, WooCommerce catalogue, Google account and Merchant data-source strategy all work together correctly.
After the installation
After the installation is complete, PW Merchant becomes part of an ongoing product-management workflow.
Store owners should continue to:
Maintain accurate WooCommerce product information.
Review new and updated products.
Correct problematic and critical products.
Monitor scheduled operations.
Review Merchant responses.
Keep WordPress, WooCommerce and PW Merchant updated.
Maintain current backups.
Review data sources when the store structure changes.
PW Merchant is not intended as a one-time transfer tool.
It is designed to support a repeatable process in which WooCommerce products are reviewed, corrected, processed and monitored through a controlled Merchant workflow.
Developed from active e-commerce experience
PW Merchant is developed by a team that currently owns and operates three established e-commerce websites.
We work directly with real products, customers, prices, stock changes, payments, shipping, returns, advertising and daily store operations.
This experience helps us understand that installation must be practical, safe and manageable for a working business.
A plugin should not only activate successfully. It should also fit into the daily operation of the store, provide clear status information and support the user when product data or external conditions change.
This practical perspective is reflected throughout the PW Merchant installation and management workflow.
