Engineered for Precision & Compliance

Why commercial teams and groups trust ShareTally over legacy consumer apps.

Zero-Sum Ledger Postings

Every transaction creates balanced double-entry ledger journals. Posted expenses are strictly immutable; edits trigger auditable compensating reversals.

4 Flexible Split Modes

Equal, Exact Minor Units, Percentage, and Weighted Shares with Hamilton-Hare largest-remainder apportionment. Never lose a fractional penny.

Multi-Tenant Isolation

Enterprise workspaces with strict tenant boundaries, RBAC permissions, encrypted attachments, and UK GDPR-compliant audit logs.
