One ledger under the whole business.

Settlements, reconciliation, accounting, GST, inventory and payouts share one ledger and one event log. Nothing has to be reconciled back, so a number on one screen is the number on every screen.

A real ledger, not a report.

Double-entry from the ground up. Every figure traces to a voucher, and every voucher to the event that caused it.

Chart of accounts

103 accounts for Indian e-commerce. Create, edit, archive, restore.

Journal

Every posting, filterable, with drill-down to the lines behind each voucher.

Account ledgers

Opening balance, postings in date order, running position, close.

Trial balance

From the ledger, not from exports. Balanced, or it says so.

Profit and loss

Cost of sales from real weighted-average costing.

Balance sheet

Assets against liabilities and equity, with the gap stated when it does not tie.

Manual vouchers

Accruals, provisions, depreciation. The entries no marketplace sends.

Fiscal periods

Close and reopen. Closing is blocked while a posting is known to have failed.

Posting map

39 rules from marketplace event to account. Your CA can redirect any fee.

Integrity checks

Nine, on demand: trial balance, vouchers, balance sheet, postable accounts, closed periods, append-only journal, tenant isolation, failed postings, inventory ties.

ERP export

Journal lines as CSV for Tally, Zoho, Busy and QuickBooks.

What the marketplace kept.

Every settlement line reconciled against the orders behind it. Not a sample, and not a total-versus-total check that misses everything interesting.

Settlement reconciliation

Each payout split into fee components and matched to the orders it covers.

Leakage findings

Referral overcharges, returns never reimbursed, refund commission retained, payout mismatches. Each with a claimable amount.

Settlement detail

Gross to net for one payout, in the order the money moves.

Claim filing

soon

File and track disputes until the money lands.

Set up for your business, not a template.

Every customer gets an engagement. What varies is its size, not whether you get one.

Fee schedule mapping

Your negotiated rate cards encoded rule by rule, so a discrepancy is measured against your contract.

Channel connection

Seller accounts, bank feeds and GST credentials wired up and proven against a real settlement.

Chart of accounts setup

Configured to match how your CA already books, so the ERP export needs no cleanup.

Posting rules

Where each fee, tax and adjustment lands, agreed with your CA before the first entry is written.

First close, run together

The first reconciliation and the first month-end with your team, not handed over as a document.

Custom recovery workflows

soon

Claim handling shaped around the disputes your channels actually raise.

Stock, tax and payouts.

The parts of commerce finance that decide whether your margin is real.

Inventory and valuation

Weighted-average costing, so cost of sales is computed rather than guessed.

Stock movements

A subledger with a running position, reconciled against the ledger.

Returns

Where returned units stopped, and which were reimbursed.

Purchases and opening stock

Manual or bulk CSV, all-or-nothing so a half-imported file cannot happen.

TCS and TDS

Section 52 and 194-O tracked per settlement, with a compliance calendar.

Supplier payments

Maker-checker. Whoever raises a payout cannot approve it.

Output GST

soon

CGST, SGST and IGST determination on sales.

GST reconciliation and ITC

soon

GSTR-2B matching, input credit recovery, vendor filing status.

Ask your books.

Questions answered from the ledger by a bounded set of tools. The model picks the question. The platform supplies every number.

Ask Cosmo

Plain questions, answered with the figures the answer was built from.

Twelve question types

Profit, revenue, margin, expenses, balance sheet, cash, inventory value, inventory health, books health, tax, forecast, payouts.

Refuses rather than guesses

Five refusals: unrecognised, not permitted, not licensed, no data, out of scope.

Role-aware

Every answer re-checks the asker's permissions, so it cannot surface what they may not see.

Runs without a model

Keyword routing handles the common questions. A slow model costs you phrasing, never numbers.

Your model or ours

Any OpenAI-compatible endpoint, or a small model inside your network. No code change.

Built to be audited.

What a CA or a security reviewer asks first: who sees what, what cannot be changed afterwards, and what happens when two businesses share a database.

Tenant isolation

Postgres row-level security under a non-owner role. A missing WHERE clause still cannot read another business.

Permissions, not roles

Every screen requires a named permission. Roles are templates that expand into permission sets.

Append-only journal

No UPDATE or DELETE grant on the journal. A correction is a reversing entry.

Event-sourced

One settlement line feeds reconciliation, ledger, GST and inventory from a single append-only log.

Maker-checker

Whoever raises a payout cannot approve it, enforced by the platform rather than by policy.

Module licensing

Each module is separately licensable. The sidebar renders from your entitlements.

Money as integer paise

End to end, so no figure is the result of a floating-point multiplication.

Single sign-on

soon

Verification against your identity provider.

See what your marketplaces kept.

Thirty minutes. We walk the ledger, the reconciliation and the journal entries end to end, on demo data or on a settlement of yours.
