Getting started

You don't have to switch overnight

Most firms start with one entity and expand gradually.

Step 1
Start with one entity
Run one audit in CORAA alongside your Excel workflow. Same data, same entity, just to compare.
Step 2
Compare the results
Same data, same entity. Compare the time spent and the output quality side by side.
Step 3
Expand gradually
Move more entities to CORAA as you get comfortable. Keep Excel for ad-hoc work, the two coexist.
Questions

The kind we answer before you ask them.

No. Most firms continue using Excel for ad-hoc analysis, quick calculations, and scenarios where a spreadsheet is genuinely the best tool. CORAA handles the structured, repetitive audit procedures, ஒத்திசைவுs, scrutiny, ஆவணப்படுத்தல், where manual spreadsheet work is slowest and most error-prone. The two coexist comfortably.
Yes. CORAA imports Tally data directly, XML or JSON exports. The difference is that instead of manually cleaning and formatting that export, CORAA ingests it directly and runs audit procedures on it. Your Tally workflow stays the same.
That's a genuine concern. Two things help: first, CORAA's interface mirrors the audit workflow your குழு already follows, பேரேடு ஆழ்ந்த ஆய்வு, ஒத்திசைவு, பணிக்காகிதங்கள், so the mental model is familiar even if the interface is new. Second, most firms start with one procedure (usually வங்கி ஒத்திசைவு) and expand gradually. Nobody needs to learn everything on day one.
For a single, well-built Excel template on a single entity, the time difference is modest. The gap widens with volume. At 20 entities, you're running that template 20 times, fixing 20 sets of import errors, and managing 20 sets of பணிக்காகிதங்கள். CORAA processes all 20 in the time it takes to do one manually. The ROI is a function of scale.
If you're a sole practitioner with a small, stable வாடிக்கையாளர் base and your Excel workflow is well-optimized, the ROI may not justify the switch today. Where CORAA starts making clear financial sense is around 10-15 entities, where the cumulative time savings and compliance benefits outweigh the subscription cost. We'd rather be honest about that than oversell.
Yes. CORAA covers the structured audit workflows, ஒத்திசைவுs, scrutiny, பணிக்காகிதங்கள், but nothing stops you from exporting data to Excel for ad-hoc analysis, custom calculations, or one-off scenarios. Many firms keep Excel as their scratch pad while CORAA handles the heavy lifting.
