I subscribed to this script last month and it has proved invaluable to be for managing my domains.

I used to list the domains I purchased in a spreadsheet listing registrar/expiry/wherepurchased/pricepaid/etc - and it became to big a task

with this script I just enter the domain + price paid - and click lookup the registrar/IP/parking/expiry/etc is filled in.

When I subscribed I had over 500 domains (.ca+.com) and paid a small fee to the developer to have my domains entered in a batch - and I have added as required since then

I have no affiliation with this person - just a handy script and a timesaver

there is a 30-day trial
