PostFinance for WooCommerce Plugin

The plugin WebStamp for WooCommerce allows you to create stamps directly from within your WordPress backend without logging into your WebStamp account each time.

Stamps are created via the integrated editor which supports all domestic and international WebStamp products, print media (no custom media) and uploading a custom image for the stamps. The WooCommerce integration allows you to automatically copy the address data from WooCommerce orders. Notice: The editor and the plugin can also be used without WooCommerce.

Stamps are ordered via a secure SSL connection and can be downloaded from the WordPress backend anytime (until the expiry date).

With the template feature you can order stamps within no time. Create templates for often used stamp types and complete an order with a few clicks. You can also add links to WooCommerce order confirmation emails to admins to speed up the order process even more. Additionally, you can add tracking numbers with links to the website of the Swiss Post to customer’s emails. The plugin also supports the WooCommerce Shipment Tracking plugin by automatically adding the tracking number to the order if the plugin is active.

Plugin updates are available on the plugins screen of your WordPress backend after activating the license.

Plugin bundle

WebStamp for WooCommerce can also purchased as a bundle which also contains the plugin Barcode for WooCommerce (see right side for prices). When renewing a bundle license you get 30% off the original bundle price.

The bundle allows you the order and print both parcel labels and letter stamps directly from within WordPress.
