Minborg by Benwin Thattil · Bengaluru

You should be able to see where the money goes.

This is where I think out loud about finance and systems: books that reconcile, GST and ITC, ERPs like Odoo, Zoho and Tally, controls that survive a resignation, and where AI tools actually help a finance team. Here’s what I usually find in a set of books, and five questions worth asking about your own.

I’m a CA Finalist with 8+ years across statutory audit, internal audit, financial analysis and controllership in India and the UAE, and I currently lead finance as Financial Controller at a lifesciences manufacturing group in Bengaluru.

Where most books startEntries scattered across systems, spreadsheets and memory.

The workEvery entry traced, matched and put where it belongs.

Where they finishReconciled, structured, and easy to explain.

Insights

The books are being kept. Nobody owns the numbers.

Most growing businesses reach a point where the accounting is technically happening. Entries get made and returns get filed, and yet nobody can say with confidence why the bank doesn’t tie out, whether the input credit is real, or whether the system is recording tax correctly.

That’s usually not a staffing problem. It’s a structure problem: a chart of accounts that grew by accident, an ERP set up by someone who didn’t know Indian tax, and reconciliations that were never made anyone’s job. I see it in owner-run businesses of every kind, from growing traders and manufacturers to agencies and services firms.

What I usually find

The same few things, in most of the books I see

None of this is a criticism of anyone’s staff. It’s what happens when a business grows faster than the systems meant to serve it.

  1. The bank reconciles. The sub-ledgers don’t.

    Cash ties out, because somebody checks it. Vendor and customer ledgers carry old entries nobody has owned for months, and no one can say which ones are real.

  2. The chart of accounts just grew.

    Accounts got created one at a time, whenever a transaction didn’t fit. The same cost sits in three places, so no report built on it can be trusted.

  3. ITC that nobody has matched.

    Input credit is claimed from the purchase register, not from what vendors actually filed. The gap only shows up when a notice arrives.

  4. Inventory and the ledger tell different stories.

    For businesses that hold stock, movements get recorded in operations and never tied back to the accounts. Margins are quietly wrong, and usually wrong in the flattering direction.

  5. The ERP was set up by someone who didn’t know Indian tax.

    GST and TDS are set up well enough to pass an entry, not well enough to produce a return. Every month ends with manual corrections nobody has time to question.

  6. Month-end is a person, not a process.

    It works because one person remembers the order of it. Nothing’s written down, so the routine resigns when they do.

Ask yourself

Five questions about your own books

No sign-up, no download. Read them and see how many you can answer without asking somebody.

  1. Can you see today’s cash position without asking anyone?
  2. Does the input credit in your books match what your vendors actually filed?
  3. Does your ERP produce your GST return, or does someone rebuild it in Excel?
  4. If your accountant resigned tomorrow, is the month-end routine written down anywhere?
  5. Can you explain the gap between your bank balance and your books, line by line?

If two of them gave you pause, that’s not unusual and it’s not a crisis. It’s a conversation worth having, and the first call about a project is free.

Talk it through

A view I bring with me

The finance function owns the numbers

A finance team isn’t only there to make payments and reconcile the bank. It owns the numbers, and it should be able to expect that those numbers count when decisions get made. That’s the standard I work to.

The second view follows from the first: a business isn’t its owner’s second bank account. Money that leaves without a decision behind it still has to be explained at year end, usually by whoever had the least to do with it. It’s better to take money out as salary, dividend or drawings that are decided and recorded than to have the books bent around it afterwards.

I’d rather say this up front than find out halfway through that we disagree.

Systems I’ve built

Built where the work needed it

None of this was built for its own sake. Each piece exists because the work couldn’t be done properly without it.

ERP automations

Small automations around an Odoo setup, written in Python, so that routine postings and checks happen without someone retyping them.

An HR and people portal

Attendance and payroll in one record, so the month reconciles without anyone keying the same data twice.

Invoicing tooling for Indian businesses

GST-aware, built around an April–March financial year, with receipt tracking and PDF invoices. Generic tools assume a January year, and someone ends up fixing every document by hand.

Who’s writing this

Benwin Thattil

I’m a CA Finalist with 8+ years on books from both sides: statutory and internal audit first, then financial analysis and running the finance function, in India and the UAE.

Today I’m Financial Controller at a lifesciences manufacturing group in Bengaluru. I own the books, the month-end close, GST, MIS and treasury, I’ve run the company’s ERP through an upgrade, and I’ve written most of the finance SOPs the team works from. Audit teaches you what a weak control looks like from the outside; running the function teaches you why it got that way.

Minborg is my own space for that thinking, and for the work that comes out of it. It’s just me, and I take on Minborg work in evenings and on weekends with my employer’s consent. I’m a problem solver more than a specialist in any one tool. If a process is broken, I’ll learn whatever fixes it.

I also co-founded finMend with a friend. It’s a separate partnership.

Software, including AI

How your information is handled

I use AI tools for some of the work, mostly reconciliations and other mechanical matching, where a machine is simply faster. I’d rather say that plainly than have you wonder. Three commitments come with it.

  • Nothing of yours goes into a free or public chatbot. Where I use AI tools on your data, it’s on a paid business account with training on your data switched off, used from my own machine, under the same confidentiality as everything else.
  • Your information is never used to sell anything, and it’s never passed on unless a law or a government order requires it.
  • The judgement stays mine. A tool can be a faster pair of hands. It can’t be accountable for a number that goes to your board, your auditor or the department. I am.

Work with me

If you’d like to talk to me directly

Most of this site is for reading. If something here sounds like your books, there are three ways to take it further. All of them happen in evenings and on weekends, remotely by default, with an occasional in-person meeting in Bengaluru.

1. A project for your business

Short projects for businesses: books reviews and cleanup, GST and ITC reconciliation, ERP cleanup and setup (Odoo, Zoho or Tally), SOPs and controls, MIS packs people actually read, and practical AI adoption in finance.

The order is always the same: read the books as they are, reconcile and correct, set the system up properly, then train your team and hand over. Every project starts with a scoped estimate, billed by time and agreed in writing before anything starts, and it’s designed to end. Because the work happens in evenings and on weekends, we’ll agree a realistic timeline up front.

The first call about a project is free.

Book a free first call

Not offered: audit or attest work, legal and litigation matters, bulk data entry from physical vouchers, and filing past-due statutory returns unless we agree it separately.

2. A paid consult

One session for one question, worked out on your numbers with the assumptions written down:

  • Income tax: filing and planning. Returns that aren’t straightforward (capital gains, more than one employer in the year, property), and the old-or-new regime choice on your actual numbers.
  • Personal budgeting and cash flow. Where the money comes in, where it goes, and a simple monthly plan you can keep.
  • A business finance question. A GST doubt, a salary structure, or how to take money out of the business properly.

The fee is a scoped estimate, billed by time and agreed in writing before we book. This is general financial education and tax help. I don’t recommend investments, mutual funds, stocks or portfolios, and I don’t recommend insurance products.

3. Senior finance roles

Open to senior finance roles and fractional engagements. LinkedIn is the best place to start that conversation.

Say hello

If something here made you think about your own books, or you’d like to argue with it, I’d like to hear from you. For a project, tell me which system you’re on, roughly how big the business is, and what you’d like fixed. I take calls in the evenings and on weekends.

Based in Bengaluru. Remote by default, with an occasional in-person meeting in Bengaluru.
