Data Pulled From the Portal
Returns, challans and notices are fetched from the GST portal directly, so you are not re-keying what the portal already knows.
Multi-GSTIN From the Start
Add every GSTIN you handle on the free tier. The limits that matter are on advanced reports, not on how many clients you may manage.
