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).

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.
