AI-supportive, full ERP foundation

One system for sales, billing, and payroll — across every brand you run.

Tathyank is a full ERP: CRM, quotes and orders, billing and payments, multi-brand and multi-store organizations, and multi-currency — plus HR and payroll built for Indian statutory compliance (PF/ESI/PT/TDS) from day one, not bolted on.

Sales, billing & multi-brand

A full ERP, not a payroll add-on.

CRM built in

People, companies, and deals live in one pipeline your sales team already works from — no separate CRM subscription to keep in sync with billing.

Quotes, orders & billing

Quotes turn into orders, orders turn into invoices, and pay links or a hosted checkout page collect payment — one connected flow instead of exports between disconnected tools.

Multi-brand & multi-store

Run more than one brand or storefront from a single account. Each organization is its own isolated store with its own team and data, nested under one tenant — not a second subscription.

Multi-currency

Price, bill, and report across currencies with managed exchange rates, so a multi-brand business isn’t forced onto a single home currency.

HR & payroll

Attendance, leave, and Indian statutory payroll — run correctly the first time.

Attendance & leave

Self-service daily attendance, leave balances and requests, comp-off for worked holidays, an org-wide holiday calendar, and audited leave encashment — with manager approvals that check reporting-line ownership before anyone can act.

Payroll built for Indian statutory law

Configurable salary structures feed a draft-then-execute monthly run engine. PF, ESI, Professional Tax, Labour Welfare Fund, and statutory bonus are computed automatically; income tax runs both old and new regimes with a preparer/verifier split on every declaration.

Separations & full-and-final

Gratuity and full-and-final settlements are modeled as first-class payroll objects, not spreadsheets bolted on afterward — every payslip and tax computation sheet is self-service from day one.

Platform

Role-based access, encryption at rest, and transaction-safe writes — as defaults, not add-ons.

Multi-tenant by construction

Every account is isolated at the data layer, not just the UI. Onboarding takes minutes: claim your workspace, and your team signs in at its own branded subdomain — no shared login screen, no manual setup ticket.

Security & encryption at rest

Role-based access is enforced at the feature level, not the page level. Personally identifiable fields are encrypted per tenant with field-level AES-GCM, and every domain write goes through transaction-safe commands.

Full audit trail with safe undo

Every change to a record — an invoice, a payroll run, a leave approval — is logged and reversible. Nothing is a silent overwrite; every write is traceable back to who made it and when.

Instant search across every record

Customers, orders, employees, and payslips are all indexed the moment they change, so finding a record is a search box away instead of a support ticket.

Custom fields & automated workflows

Extend any record with fields specific to how your organization works, and let business-rule-driven workflows handle routing and approvals automatically instead of chasing people over email.

Coming soon

An AI-native foundation

An in-app AI assistant will be able to query your records across sales, billing, and payroll and draft actions through the same role-scoped, tenant-isolated APIs your team uses, read attached documents and images, and route every proposed change through a human approval step before anything writes to your ledger.

Multi-brand, multi-store, multi-tenant

Your own subdomain per brand. Your own data. No exceptions.

Claim a workspace address during onboarding and your team lands straight on a branded, tenant-locked login — no shared portal, no manual tenant picking, no cross-tenant data path. Running more than one brand or store just means another isolated organization under the same account, not a second subscription.
