What is SagacityBooks?

SagacityBooks is GST billing and accounting software for Indian businesses and CA firms. It covers invoicing, books of account, bank and Tally import, e-Invoicing, GSTR-2B reconciliation and one-click GST return filing.

Can SagacityBooks file GST returns directly?

Yes. GSTR-1, GSTR-3B and GSTR-9 can be prepared and filed to the GST portal, with validation that catches errors before submission.

Does it work without internet?

Yes. SagacityBooks installs as an app and keeps billing when the network drops. Invoice serials are leased in advance so numbering stays consecutive and gap-free as GST Rule 46(b) requires, then syncs when the connection returns.

Does SagacityBooks work with Tally?

Yes. You can import your Tally Day Book and export or push vouchers back to Tally, so there is no double entry.

Is there a free plan?

Yes. You can start free with no card, and upgrade as your business grows.

Billing that follows you out of the office

The same books, worked from a phone, a shop counter, or a customer's WhatsApp — no separate app, no re-entry.

📱 Bill from your phoneA one-screen billing form built for a thumb. Pick the party, scan or tap items, done — the full desktop form is a tap away when you need it.

🛒 Counter till & barcodeScan with a USB scanner or the phone camera, take payment, and print a 58 mm thermal receipt.

📴 Keeps working offlineBill through a dead connection. Invoice numbers are reserved in advance, so the series stays consecutive and gap-free for GST Rule 46(b), then syncs when you're back.

💬 Send on WhatsApp, get paid by UPIEvery invoice gets a private link your customer can open without an account — bill, UPI QR for the balance due, and a PDF to keep.

⏰ Payment remindersSee who owes what and for how long, then remind them in bulk. Each party shows when it was last chased.

🔁 Recurring invoicesRent, retainers and AMC raised on schedule. Month-ends are handled properly — 31 Jan becomes 28 Feb, then 31 Mar again.

🏷️ Price listsRetail, wholesale and distributor rates — a fixed rate per item or a straight percentage off. The customer's card applies itself.

🖼️ Item photos & themesPut pictures on items so the right one gets picked, and choose an invoice look — five layouts, six accent colours.

🌐 English, हिंदी, मराठीStaff and customer screens speak the language your counter does.

Why Sagacity

Built for Indian GST — not adapted to it

From your first invoice to a filed return, Sagacity keeps books and compliance in one place. No exporting to spreadsheets, no re-keying into the GST or NIC portals, no month-end scramble — the numbers you enter once flow through invoicing, e-Invoicing, reconciliation and returns.

Accurate returns — validation catches HSN, UQC and doc-issue errors before the portal does.
Nothing missed — GSTR-2B ITC matching and bank reconciliation flag every gap.
Less manual work — Tally sync, bank auto-import and AI bill-reading cut re-typing.
Right access — role-based rights keep filing to your office and data to your staff.
