Edit EDGAR files online with zero hassle and full control.

RDG’s ThunderDome®

ThunderDome® enables multiple-users to create and edit their EDGAR documents directly online. This tool eliminates the need to hand-mark changes, send them to your provider, wait for them to send you a proof, and then review the proof for accuracy. Moreover, in addition to your ability to make edits to your filings directly, you will also have 24/7 access to our full-service team if there are ever edits you would prefer to have us do on your behalf.

Why ThunderDome®?

Unlike bloated enterprise platforms, ThunderDome® is focused. It does exactly what SEC filers need—with less friction, faster support, and pricing that makes sense.

EDGAR Control

The exclusive cloud-based ThunderDome® allows multi-user access to create, manage, edit, and file EDGAR and Non-EDGAR documents with the SEC. The cloud-based portal creates significant efficiencies to users as it enables version control and collaboration while also eliminating the need to manually hand-mark EDGAR changes only to then wait for your provider to return a proof.

RDG has designed this to be a Hybrid solution, so our clients enjoy the perfect combination full-service expertise when they need it, and in-house control when they want it. Our EDGAR professionals remain available 24/7 for full-service EDGAR conversion, editorial service, and support.

iXBRL Expertise

Our US-based experts do all the XBRL tagging and validation on a full-service basis, with an Account Manager available to you for questions and consultation. You will simply review the tagging using our advanced online XBRL review tool, which is an integral aspect of ThunderDome®.

RDG’s combination of Service & Software is the best of both worlds. Full-service expertise when you need it and in-house control when you want it.
