The Problem

CA firms are stuck between WhatsApp, Tally, and Excel.
Scale and accuracy suffer.

40-60 hours wasted per month per firm — with no real-time financial picture.
Before Cyntrova
Manual accounting across tools
WhatsApp intake, Tally typing, Excel reports, and manual GST work.

High error risk
Bank reconciliation in Excel and VLOOKUP
Matching receipts and payments happens manually, month after month.
Manual matching
GST filing and reports built manually

How Cyntrova Works With You

You're always in control.
Nothing posts without your say.

Cyntrova does the heavy lifting, but every posted entry is approved and fully auditable. No surprises. No black box.

What Cyntrova does automatically
Collects, validates, prepares
Receives invoices from client, vendor, and CA uploads

Prepares clean data for exception review
What you decide
You review. You approve.
You approve exceptions before posting

Posted entries require reversal for corrections
Cyntrova acts like a junior accountant — processes everything, flags issues, and lets you approve before posting.
Security & Trust

Security posture built for high-trust CA firms

In this domain, trust is everything. Cyntrova is designed around defense-in-depth controls so every invoice workflow stays protected, isolated, and auditable.

Security Standard
Defense-grade safeguards active today. Security controls are continuously hardened and verified before being published here.

Where controls already align with financial-grade practices, we highlight them clearly. Remaining controls are tracked in hardening sprints and rolled out with verification first.

Identity Shield

Role-based access and approvals

Firm owners, admins, accountants, reviewers, and clients see only what they are allowed to see.

Tenant Isolation

Per-firm and per-client boundaries

Records are scoped with ownership filters to keep one firm's data isolated from every other workspace.

Transport + Storage

Encrypted flow with controlled file access

Invoices move through encrypted channels, and file access can be constrained with signed, time-bound retrieval patterns.

Data Integrity

Idempotent posting and transaction safety

Every financial action is atomic and idempotent so entries cannot post twice.

Abuse Defense

Rate-limits and payload controls

Upload throttles, auth rate-limits, and strict file constraints reduce abuse surface before it reaches processing layers.

Auditability

Immutable audit trail and period locks

Every action is logged with who, when, and why — with period locks for controlled close.

Comparison

Questions

Common questions before switching to Cyntrova

Everything CA firms usually want to know before adopting an accounting OS.

Is Cyntrova a Tally replacement or can I run it alongside Tally?
Cyntrova is the source of truth. A Tally bridge export is available for migration or parallel runs while you transition.
How do you ensure accounting correctness?
A deterministic double-entry engine enforces balance on every entry, with audit trails, idempotency, and period locks.
Does AI post entries automatically without approval?
AI extracts and suggests, while humans approve exceptions. Totals are calculated deterministically and posted with audit trails.
Do clients or vendors need logins to upload invoices?
No. Each client and vendor gets a unique link. No login, no app, no setup.
What bank reconciliation methods are supported?
Upload statement PDFs today. Account Aggregator (AA) integrations are planned. Matching is multi-pass and always human-confirmed.
Which GST reports are included?
GSTR-1 export, GSTR-3B summary, and GSTR-2B reconciliation with ITC-at-risk reporting.
Is data isolated per firm and client?
Yes. Every firm and client workspace is isolated with role-based access controls and audit logs.
Can I migrate existing data?
Yes. Import opening balances and master data, and export to Tally XML during migration if required.
