CA Payal Jain

Kaloti and Lathiya Chartered accountants Bhilai – Chhattisgarh

testimonial-img

As a practicing Chartered Accountant, I’ve been using **Tally Prime** for several clients’ accounting and GST compliance requirements over the past few years. Tally has proven to be one of the most dependable tools for managing day-to-day bookkeeping, preparing GST returns, and ensuring accuracy in compliance

testimonial-img

CA Swarnim Rai

M/s R Rishi and Associates Bhopal, MP

testimonial-img

With Tally Prime’s direct GSTR‑1 upload feature, our compliance time has shrunk dramatically. Before switching to Tally Prime’s GSTR-1 upload workflow, our team manually exported data, logged into the portal, uploaded files, checked for rejections, and handled correction loops—and it consumed half a day every month. What once took a half-day now takes only an hour. Highly recommend this to any business using Tally for GST filing.

CA Uttam Chand

CNK Associates LLP, Mumbai – Heading the Chennai Branch

TallyPrime now helps in filing various returns and reconciling all the GST returns filed with tally data, like GSTR3B, GSTR1, 2B v/s Input claimed, 2A v/s Input claimed, IMS direct upload, etc. with so much ease.
