rung1 is software from elan1 that lets Indian businesses change their ERPNext system by asking in plain language. Every change is built on a copy of the books, checked against the ledger, stock, access, GST and the MCA audit trail, approved by a named person, recorded in a proof record, and can be undone for 30 days.
Indian manufacturers, distributors, traders and multi-location retailers with ₹5–50 crore turnover who carry inventory, already e-invoice, and have a CA who will take a call. It is not for service firms under ₹1 crore or firms above ₹250 crore.
No. rung1 is software that builds, checks and records ERPNext changes. It keeps standard ERPNext, never forks it, so any ERPNext partner can still work on your site.
A small customisation from an ERPNext partner typically costs ₹75,000–1.5 lakh and takes 4–16 weeks. With rung1, a change is built from a sentence and uses credits (a typical customisation is modelled at 600–1,800 credits at ₹0.80 each); refused changes cost nothing.
It is expected to, sometimes. Every change runs on a copy of your books first, the checks run against it, a person you name approves it, and undo is available for 30 days. A wrong change can’t reach your live books without a named approval, and it can’t stay there.
No. Changes are built and tested on a throwaway copy of your site. One service publishes, after taking a snapshot, and it restores automatically if a check fails on live.
Never. It prepares; it never pays. It never submits anything unattended, never posts into a closed period and never amends a filed return.
In Mumbai, India, including backups and logs. You own it, it’s never used to train AI models, and you can export it any time with no exit fee.
A free seat on every client site, the approval queue and an audit-pack export.
By turnover band, never per user, from ₹2,499 to ₹49,999+ a month, plus credits at ₹0.80. Refused changes cost nothing. During the design-partner phase, the 10 Phase 1 firms pay nothing for 90 days.
Yes, once we open publicly: 14 days, ₹0, 3 users, 500 credits. Nothing is billed automatically. Until then, apply for one of the 10 design-partner slots.
Not today. We list the controls we run instead on the Trust & security page, and we will publish a dated plan only when one exists.
Yes, from Q1 2027, for ₹24,999. Your CA signs the trial-balance tie-out, and Tally stays your fallback until the day-5 sign-off. Until then we import masters manually at no charge.
Never. They’re read-only sources you migrate out of.
No. Attach mode (2027) works on your site if it passes an 11-point readiness check.
No. rung1 Revenue changes only your own CRM records, and rung1 Voice only takes inbound calls from your approvers.
WhatsApp, yes: request, approve, reject and a daily digest. Phone approval (rung1 Voice) comes later, for low-risk, reversible items only.
No. Ledger, stock, access and the MCA audit-trail checks are blocking. The GST check warns; overriding it needs two people and a written reason, and the override is written into the proof record.
Building and testing a change. Reading, asking, approval, the proof record, refusals and any undo caused by our defects are free. When you run out, work stops with nothing charged; top-ups are opt-in at ₹799 per 1,000.
GST is extra and shown on one invoice line. You get one price list and one invoice, with no separate hosting bill.
You are. We are your processor. A DPA is signed before the first real record, the sub-processor list is published, and erasure is done within 72 hours of a request.
No. We are not a filing service and not your competitor. We never talk to your client about anything you haven’t seen.
It is coming, pending ICAI guidance. We will not state a rate until counsel clears it.
A record written for every change: who asked, what was built, what each check said, who approved it, when it was published and how to undo it. Records are hash-chained, so any later edit to the chain shows.
