Alternative to

What 399Apps is positioned against

AlternativeTo, SaaSHub and Crozdesk all ask which products a tool replaces. These are the nine, each linking to the page that makes the case — including where the competitor is the better buy.

Who this kit is for

If you are a directory editor, a review-site researcher, a journalist writing about Indian SMB software, or anyone filling in a listing form for 399Apps, everything here is approved for verbatim use and no permission request is needed.

Who it is not for

If you are a buyer comparing tools, read Pricing or the comparison pages above instead — this page is company facts, not a product pitch. If you want to resell 399Apps under your own brand, that is White Label, not press. If you need paid setup and support, that is Varisya.

Honesty

What we do not claim

A directory profile is a permanent public record that other sites scrape. These fields have no published figure behind them — leave them blank rather than estimating.

  • Customer, user or download counts — no number has been published, so none should be entered.
  • Funding, revenue or valuation — 399Apps is self-funded and has published no figures.
  • Headcount or team size.
  • Registered legal entity name, GSTIN, CIN and registered office address — request these from the founder before submitting to any directory that requires them.
  • A general public support phone number — support runs on email. The only published phone line is +91 99808 13847, which is school sales and demos for 399apps for Schools.
  • Awards, certifications, ISO/SOC 2 attestation, or G2/Capterra ratings not yet earned.
  • Uptime or SLA percentages.

FAQ

Press and listing questions

The questions directory editors and journalists actually send.

I'm listing 399Apps on a software directory — which description should I paste in? +
Match the field length. Use the 58-character tagline for a "one-line pitch" field, the 157-character short description for a "summary" or meta field, the ~50-word medium description where a directory shows a card, and the ~110-word long description for the main profile body. They are written to be used verbatim, so all listings say the same thing.
What category should 399Apps be filed under on a directory like G2 or Capterra? +
Accounting Software is the primary category — Nidhi Books is the anchor product. Billing & Invoicing, Inventory Management, POS and GST Software are accurate secondary categories. Filing it as ERP is defensible for the full 399 One suite but misleading for a single app, so prefer "ERP for Small Business" only where the listing covers the whole suite.
A directory is asking me for the number of customers and the funding raised. What do I put? +
Leave both blank. 399Apps has never published a customer count, and it is self-funded with no announced round. A directory profile is a permanent public record that other sites scrape, so an estimate entered once becomes a fact everywhere. The full list of fields to leave blank is in the "What we do not claim" section above.
Can I use the 399Apps logo and screenshots in an article or a listing? +
Yes — the logo, app icons, Open Graph image and product screenshot linked above may be used unmodified in directory listings, reviews, comparisons and articles about 399Apps. Do not recolour the mark, stretch it, or place it on a busy background. No permission request is needed for editorial or directory use.
Is 399Apps really a flat ₹399 a month, or is that a starting price with add-ons? +
It is flat per app, not a starting price. One app is ₹399/month excluding GST; 21 apps is ₹8,379/month. Users are unlimited on every app, so staff logins, counter logins and your accountant never change the bill. There are no feature tiers — the price does not rise for a feature, only for another app. Self-hosted and enterprise deployments are quoted separately.
Who do I contact for a quote, a founder interview or a product demo? +
Email [email protected]. 399Apps is built and supported by the same person who writes the code, so press enquiries, demo requests and technical questions all go to the same inbox and get a direct answer rather than a media-relations reply.
Press enquiries
