Overview

GST-ready accounting for small and growing businesses in India.

Nidhi Books is journal-backed accounting reimagined for the small business owner. Create GST-compliant invoices with HSN/SAC and place-of-supply handling, capture TDS on every applicable payment, reconcile customer and vendor accounts, and pull live P&L, Cash Flow, AR/AP Aging and Sales Register reports. Export GSTR-1 (with B2B, B2C, CDNR and HSN summary), GSTR-3B summary, and TDS reconciliations (26AS / 26Q) as CA-friendly CSV — or take a period-close audit snapshot with a SHA-256 hash. Available on the 399apps cloud or self-hosted with full data ownership.

What's inside

Features that earn their place.

GST-ready invoicing

Compliant invoices, quotes and credit notes with HSN/SAC, intra- vs inter-state CGST/SGST/IGST splitting, place-of-supply and UPI QR on the PDF.

Journal-backed, no headaches

Every transaction posts to the ledger. You see the simple form; the journal stays clean and auditable.

Live financial reports

P&L (accrual), Cash Flow, AR / AP Aging buckets, Sales Register and Stock Valuation — recalculated as you type.

GSTR-1 + GSTR-3B exports

B2B, B2C consolidated, Credit/Debit notes to registered customers, HSN-wise summary, and the GSTR-3B 3.1.a outward-supplies block — CSV in CA hand-off format.

TDS done properly

Capture TDS on customer payments (Form 26AS-style) and on vendor bills (Form 26Q). Section-wise summaries across 194C / 194J / 194I and more.

Audit-grade exports

Period-close snapshot: CSV manifest + PDF cover, signed with a SHA-256 hash. Statutory audits get the immutable trail they expect.

Reports & exports

Built for the way Indian SMBs actually file taxes.

Specific, CA-friendly outputs that match what your accountant actually asks for at the end of the quarter — not generic dashboards. Everything below is shipping in Nidhi Books today.

GST & statutory reports

Tax-compliant outputs ready to file or hand off to your CA.

  • GSTR-1 export (CSV)

    Outward supplies — B2B, B2C consolidated (by state × rate), Credit/Debit notes to registered customers, and an HSN-wise summary. Section-headed CSV for direct CA upload.

  • GSTR-3B summary

    Section 3.1.a outward-supplies block with taxable value and CGST/SGST/IGST breakdown for the period.

  • Sales Register

    A chronological list of every invoice and credit note for the period with full tax breakup per row. Filterable by warehouse and period.

  • HSN-wise summary

    Quantity, taxable value and tax by rate aggregated by HSN, using date-aware tax rates so historical periods stay accurate.

  • Place-of-Supply handling

    Intra- vs inter-state detection drives CGST/SGST/IGST splitting on every line, every report.

  • TDS on AR (Form 26AS reconcile)

    TDS withheld by your customers on receipts, grouped by customer and section — line up cleanly with 26AS at year end.

  • TDS on AP (Form 26Q reconcile)

    TDS deducted on vendor bills, grouped by vendor and section — covers 194C, 194J, 194I-LB and more.

Operational & financial reports

The numbers you actually run the business on, between filings.

  • Profit & Loss

    Accrual-basis P&L. Sales minus COGS (from recorded bills) minus operating expenses. GST is excluded as a pass-through.

  • Cash Flow

    Cash-basis movement — inflows from customer payments and vendor refunds, outflows from bill payments, expenses and customer refunds.

  • AR Aging

    Receivables bucketed by days overdue (current, 1–30, 31–60, 61–90, 90+) with per-invoice outstanding amount.

  • AP Aging

    Payables bucketed by days overdue, net of TDS deducted and vendor credit applied.

  • Stock Valuation

    Per-item on-hand quantity, unit cost and total stock value — shared with the Nidhi Inventory module.

Exports & data ownership

Get every record out — for CAs, for auditors, for your own systems.

  • Invoices CSV

    Full invoice list with number, date, due date, customer, status, kind, subtotal, discount, tax and total. Respects every filter on the list page.

  • Payments CSV

    Receipts list with date, customer, method, reference, amount, applied vs unapplied, TDS withheld and TDS section.

  • Customers CSV

    Customer master with display name, company, GSTIN, email, phone, payment term and state.

  • GSTR-1 CSV (CA hand-off)

    Same data as the on-screen GSTR-1, structured with section headers so your CA can drop it straight into their workflow.

  • Invoice PDF (Classic & Compact)

    Per-invoice PDF with two template strategies and an embedded UPI QR for fast payment.

  • Customer-portal PDF

    Share an invoice via a public token — your customer can view and download the PDF without an account.

  • Audit Export (period-close)

    A snapshot CSV manifest plus a PDF cover, signed with a SHA-256 hash. Becomes an immutable record of the closed period.

Heads-up. On the roadmap (not yet shipped): Balance Sheet & Trial Balance, GSTR-2B / GSTR-9, e-invoice IRN, e-way bill, XLSX export and Tally sync. We will only show them here when they are real.

FAQ

Books — FAQs

Which GST reports does Nidhi Books actually generate today? +
GSTR-1 (B2B, B2C consolidated, Credit/Debit notes to registered customers, HSN summary) as both an on-screen report and a CA-friendly CSV; the GSTR-3B 3.1.a outward-supplies summary; a Sales Register; TDS-on-AR (Form 26AS reconciliation) and TDS-on-AP (Form 26Q reconciliation). GSTR-2B / GSTR-9 / e-invoice IRN are on the roadmap.
How do I export my data? +
Every list view (Invoices, Payments, Customers) exports to CSV with the filters you have applied. GSTR-1 has its own structured CSV with section headers. Invoices download as PDF (Classic or Compact, with UPI QR). For statutory audits we also offer a period-close Audit Export — a CSV manifest plus a PDF cover signed with a SHA-256 hash.
Does it handle TDS? +
Yes. You can record TDS withheld on customer receipts (with section codes for 26AS) and TDS deducted on vendor bills (for 26Q). Both produce section-wise summaries you can hand to your CA at year-end.
Can I self-host Nidhi Books on my own server? +
Yes. Every plan has a self-hostable equivalent. You get the same product, deployed on your infrastructure with full data ownership.
Is the team / user count limited? +
No. Every plan — Starter, Growth and Scale — comes with unlimited users and unlimited exports. We don't price per seat.
Do you offer migration from Tally / Zoho / QuickBooks? +
We offer guided migration from common accounting tools. Write to us at hello@399apps.com and we will scope it for you.
Is my data safe? +
On cloud, your data is encrypted at rest and in transit, backed up daily, and isolated per tenant. On self-host, everything stays on your server.
