Build the pricing you actually sell — tiered plans, add-ons and promotional coupons — without custom code.
Put customers on recurring subscriptions and let invoices and payments raise themselves on schedule.
Automated retries and reminders when a payment fails, so involuntary churn stops leaking revenue.
The subscription metrics that matter, computed live from your real billing data — no separate analytics tool.
Every subscription invoice and payment posts to Nidhi Books, so revenue and GST stay accurate.
No per-seat or per-customer surcharge — scale your subscriber base on the flat plan.
Billing is ₹399/month on the cloud as your base app — or ₹99/month added on top of another 399apps app. No per-seat charges. Self-hosted and enterprise needs are custom-quoted.
for your first app
Fully managed on the 399apps cloud. Add more apps or add-ons at ₹99/month each — the maths always stays clear.
Run the same product on your own server with full data ownership.
Bigger scale, white-label, deep customisation and SLAs.
₹399/month is exclusive of GST, billed monthly (annual billing on request). Self-hosted and enterprise scopes are bespoke.
GST-ready invoicing, TDS-aware payments, P&L and Cash Flow, with audit-grade CSV and PDF exports.
Stock, SKUs, purchase orders, transfers, barcodes — one source of truth for every product you sell.
Books + Inventory, working as one — ₹399 + ₹99 = ₹498/month on the cloud.
A short call. We will scope your setup, recommend cloud vs self-host honestly, and quote without games.
