The audit OSfor India's CA firms.
Arya and Saathi handle 3CD clauses, GST reconciliation and client follow-ups — so your CA firm can focus on the work that matters.
How Arya runs a tax audit,
from plan to UDIN.
The TACT workflow your firm runs today, with Arya doing the heavy lifting and the audit trail building itself underneath.
TDS reconciliation plan
- 1Download Form 26AS for FY 2025-26
- 2Extract Tally TDS schedule, sections 192 / 194C / 194J / 194I
- 3Vendor-wise match against firm rate master
- 4Compose workpaper draft for Performer review
01
Plan the clause
Arya reads the ICAI Guidance Note and the firm Skills you have already encoded, then drafts the procedure list the auditor would have written by hand. Approve the plan and Arya gets to work.
Vendor reconciliation
2 flaggedBooks vs Form 26AS, tolerance ₹500
02
Run the procedures
Tools pull TRACES, Tally, and the firm rate master. Matches are deterministic, not guessed. Exceptions are flagged with the rupee impact attached so the Performer can investigate the right ones first.
