Auditing Clients on Marg, Logic, or Any Other Software: The Universal Template Route
Every CA firm has them: the pharma distributor on Marg ERP, the retailer on Logic, the client whose "system" is a customised QuickBooks export or something built in-house a decade ago. These clients are no less auditable than the Tally ones — but every audit-automation conversation quietly assumes they don't exist.
CORAA handles the mainstream systems natively — Tally, Busy, Zoho Books, SAP, NetSuite — each with its own parser for that system's export shapes. For everything else, there is a deliberately different answer: the Universal Template, a single structured Excel workbook that any accounting software's exports can fill.
We think honesty matters here: CORAA does not have a native Marg parser, and this guide won't pretend otherwise. What it has instead is arguably more useful — one onramp that works for Marg and every other system you'll ever encounter, with the data quality problems caught in Excel, before upload.
How the Universal Template Works
The template is a downloadable .xlsx workbook whose sheets map one-to-one onto CORAA's data model — the same model the native Tally and Busy parsers feed. Fill it from your client's exports, upload it, and everything downstream (Ledger Mapping, scrutiny, reconciliation, working papers) behaves exactly as it would for a natively-supported ERP.
Three design choices do the heavy lifting:
Validation lives inside the workbook. Every column carries Excel data-validation: dropdowns for voucher types and bill types, format checks that put a red error ring on an invalid PAN, GSTIN, or date, and hover prompts explaining each field. Bad data is rejected while the article assistant is filling the sheet — not days later as a failed upload.
Tiers match effort to what you need. You don't fill all of it. The workbook is organised in three tiers:
| Tier | Sheets | What it unlocks |
|---|---|---|
| Tier I | Entity profile, account groups, ledgers, current-year trial balance, vouchers and voucher lines | The core: trial balance, ledger scrutiny, transaction testing |
| Tier II | + Prior-year TB, bills outstanding, GST details, TDS/TCS entries, cost centres, related parties | AR/AP party-wise ageing, opening-balance verification (SA 510), Form 3CD party-driven clauses, related-party work |
| Tier III | + Fixed assets, stock items, payroll dues, contingent liabilities, bank statements | PPE roll-forward and depreciation, MSMED and payroll-dues testing, contingent-liability disclosures, SA 501 inventory work |
A Tier I fill from a Marg client's ledger and day-book exports is enough to run the core audit. Each additional tier is a conscious trade: more filling effort, more working papers unlocked.
Cross-validation runs before processing. On upload, the platform checks that the trial balance self-balances (total debits equal total credits), that the GL activity actually sums to the TB it came with — in aggregate and account by account — and flags the specific accounts that don't tie. A population that doesn't reconcile to its own trial balance is caught at the door.
The Marg Workflow in Practice
Marg exports its standard reports — trial balance, ledgers, day book, outstanding registers — to Excel. The practical flow for a Marg client is:
- Ask the client for the year's Excel exports: trial balance, ledger-wise transaction detail, and day book at minimum (Tier I), plus the prior-year TB and outstanding/party registers if you're going past it.
- Fill the Universal Template's sheets from those exports — largely a copy-paste-and-tidy exercise, with the workbook's own validation flagging problems as you go.
- Upload. Cross-validation confirms the data ties to its own TB; Ledger Mapping assigns every ledger to its Schedule III line, routing anything uncertain to the Unmapped queue for the engagement team.
- Run the modules and review the working papers — identical from here to any Tally or Busy engagement.
One boundary worth knowing: the template carries book data only. Classification decisions — which TDS section an entry falls under, which Schedule III bucket a ledger belongs to — happen inside the platform after ingestion, confirmed by the auditor. The workbook records what the client's system recorded; it doesn't ask a junior to make classification calls in Excel.
Frequently Asked Questions
Does CORAA integrate with Marg ERP directly?
No — there is no native Marg parser today. Marg clients are supported through the Universal Template: fill the workbook from Marg's Excel exports and upload. Downstream processing is identical to natively-supported systems.
How long does filling the template take?
For a typical SME client, a Tier I fill from clean exports is a few hours of assistant time — compare that against manually building the same trial balance, ledger and voucher working papers from the same exports. Tiers II and III scale with how much of the optional evidence you want generated.
What happens if the data I upload doesn't balance?
The upload's cross-validation reports it specifically: whether the TB itself doesn't balance, or the GL doesn't sum to the TB, and which accounts mismatch. You fix the source sheets and re-upload — nothing unbalanced flows silently into working papers.
Is this also the route for QuickBooks, Sage, or an in-house system?
Yes. The template is system-agnostic by design — if the software can export a trial balance and transaction listing to Excel, the workbook can be filled from it. That is the point: one onramp for the long tail, instead of a parser per product.
