Datalinc GST Docs for WooCommerce by Datalinc Pty Ltd helps GST-registered Australian WooCommerce merchants issue Tax invoice and Adjustment note PDFs from paid orders and qualifying refunds.
Helps produce documents that include the details in GST Act s 29-70 / s 29-75 (and LI 2022/31 for adjustment notes). Not legal advice. Not a BAS lodgement service. Not affiliated with the ATO.
Local PDFs (always included)
Tax invoice and adjustment note PDF generation ships in this plugin and runs entirely on your WordPress/PHP server (Dompdf). No site key is required to issue documents on paid orders. Order PII and PDF bytes are stored on your site and are not sent to wootf.com for storage.
Optional companion service at wootf.com (Guideline 6 serviceware)
A site key from wootf.com is an optional service account for features that cannot run locally: live ABR ABN lookup and GST-registration period checks via the wootf.com companion API. Without a key, settings show that the ABR companion is disconnected — PDFs are not locked. The site key does not unlock hidden local files. There is no time-limited trial and no encrypted/hidden PHP.
