PracticeStacks is a modern practice management tool aimed at Indian CA and tax consulting firms. It provides clean task tracking, recurring job templates, and team assignment boards. It suits firms looking for a straightforward way to see which staff member is working on which client return without heavy legacy software.
CAfirmOS provides an end-to-end operational platform. Beyond task boards, CAfirmOS directly addresses the two biggest daily bottlenecks in a CA office: getting documents out of clients and recovering unbilled fees. CAfirmOS sends WhatsApp reminders with secure upload links so clients can submit bank statements without logging into complex portals. The system then runs OCR checks on the uploads and links completed work to automatic retainer invoices with UPI QR codes.
If your primary goal is clean internal task delegation, PracticeStacks is a capable option. If your firm struggles with client delays, missing statements, and payment recovery, CAfirmOS provides a more complete solution. Explore the CAfirmOS landing page and features

How to decide
Consider your team size and where your staff spends the most non-billable time.
Choose PracticeStacks if you need basic task boards for a small, static team
If you have a fixed team of two or three people and only need to see task status in a visual board, PracticeStacks gives you a clean interface.
Choose CAfirmOS if you have article assistants joining and leaving regularly
With flat per-firm pricing, you never have to reallocate licences or pay more when you hire articles for peak tax season.

Review how many hours your staff spends asking clients for bank statements, password-protected PDFs, and pending fees. If that administrative chase is your primary frustration, CAfirmOS directly solves it.
