One platform, many modules

Connected ERP apps for an organisation of any scale.

Most businesses run finance in one system, people in another, and spend the month reconciling the two. Extrr builds each module on a single ledger, a single identity and a single audit trail — so the modules agree by construction, not by export.

Why connected

An integration is a promise. A shared ledger is a guarantee.

Bolting two systems together means reconciling them forever. When every module writes to the same immutable ledger, there is nothing left to reconcile — the question "do the numbers agree?" stops being a question.

Nothing is ever overwritten

Posted entries are append-only. A correction is a new, linked reversing entry — so last quarter's books still say what they said last quarter.

Add a module, not a migration

Each app is a surface over the same core. A new module inherits your chart of accounts, your users, your approvals and your history on day one.

Every change has a name on it

Whoever proposes a posting cannot approve it, people and software are held to the same rule, and the record is verifiable rather than merely stored.

Live today

Finance & Accounting

A double-entry ledger that cannot silently drift, with Indian statutory work built into the posting path rather than bolted on at year end. Debits equal credits or the entry is refused — there is no "unbalanced" state to clean up later.

  • GSTR-2B reconciliation against your purchase register, with ITC eligibility and Rule 88D mismatches surfaced per invoice.
  • Payables end to end — bill intake, cross-validation against 2B, delegated approvals with segregation of duties, payment runs and bank files.
  • Statutory, not an afterthought — TDS/TCS, PT/PF/ESI, advance receipts, Schedule II depreciation, AS-22 deferred tax and financial statements in Schedule III format.
  • Agents that propose, never post — reconciliation, close and a read-only query agent. Anything that touches the ledger goes through a human approver.

HR & Payroll

The next module. Today payroll means running it in one system and journalling the result into another, then arguing about which is right. Built on the same ledger, a payroll run posts once — with every statutory head already understood by the books it lands in.

  • One employee master, shared with the vendor, approval and audit machinery finance already uses.
  • A payroll run that posts through maker-checker, into the same immutable ledger, with PF, ESI, PT and TDS landing in the heads finance already maintains.
  • No month-end reconciliation between HR and finance, because there are not two sets of numbers to reconcile.
Talk to us about HR

We would rather describe this honestly than sell it early: no HR code has shipped yet. If payroll is what you need first, tell us — it changes what we build next.

Not built yet

A sketch, deliberately — there is no screen to show you.

Start with the books. Add the rest as it ships.

Finance & Accounting is live and in use today. Everything that follows is built on the same ledger you start with, so adopting the next module is an addition rather than a migration.
