Sound familiar?

What slows finance teams down today.

Month-end takes two weeks

Bank, gateway, COD and marketplace statements are matched by hand before the books can close.

Input tax credit slips away

Supplier invoices missing from GSTR-2B are found too late to fix.

Collections depend on calls

Receivables age because reminders are manual and payment is hard for the customer.

The CFO sees last month

Cash, payables and margins arrive in a spreadsheet weeks after the fact.

What changes

From workarounds to one connected system.

FAQ

FinOps OS questions.

Talk to Stack18
Will our auditors and CA be comfortable?

Yes. The ledger keeps a full edit log in line with the Companies Act audit trail rule, and if your CA prefers Tally or Zoho Books, the bridge keeps both in sync.

Which settlements can you reconcile?

Bank statements, UPI and payment gateways such as Razorpay, Cashfree and PayU, COD remittances and marketplace payouts from Amazon, Flipkart and Meesho.

Does it file GST and TDS returns?

It prepares GSTR-1, GSTR-3B and TDS return data with checks, ready for filing through the portal or your filing provider.

How does the MSME tracker help?

Under Section 43B(h), payments to MSME suppliers beyond the allowed period can lose their tax deduction. The tracker flags those bills before the deadline.

Is there a per-user fee?

No. You pay a one-time build and setup fee per module, and the system runs on your own cloud.

How fast can we close the month?

Most of the time goes into reconciliation and chasing. With matching and the close checklist automated, teams typically close in days rather than weeks.
