Everything in one place
One suite instead of a dozen subscriptions
Every module shares one database, so a client's deals, invoices, tickets, emails, meetings and files are one history — not ten exports glued together.
Accounting
Double-entry books, invoices, bills, payments, credit notes, bank statements, taxes and reports, with inventory on FIFO or average costing.
Tasks & projects
Tasks, projects, Scrum boards, flows and automation, workgroups and cross-functional teams, with time tracking and checklists.
Messenger & video
Chats, channels and video calls on your own server, a news feed, meetings with agendas, and a shared knowledge base with a Markdown editor.
Calendar & booking
Shared calendars with CalDAV and outside sync, resource booking, and customer booking pages tied straight to the CRM.
Drive & documents
Encrypted file storage, public links, office editing in Collabora, whiteboards, generated documents and e-signatures.
HR
Work time and check-in, absences, shift rota, work reports, HR documents with signing, employee skills and field-visit planning.
Customers
Help desk, live chat, a client portal with one sign-in link, websites and an online shop, and email marketing campaigns.
BI
Dashboards over NERP's own data, CSV files, URLs and outside PostgreSQL databases — no separate analytics product required.
Beyond the basics
A CRM that tells you what needs attention
Because sales, delivery, support and accounts live in one database, NERP can answer questions that separate tools can't.
Read the release notes →- Deal health with reasons. Each deal is scored from its activity, emails and payment history, and NERP says why.
- Next steps that worked. Suggestions drawn from your own won deals, not a generic playbook.
- A daily "needs attention" list. Silent clients, stalled deals and overdue promises, every morning.
- True profit per client. Revenue minus product cost and the hours your people really spent, per client, deal, product and salesperson.
- Cash forecast. Expected money in and out, from open invoices, bills and pipeline.
- Promise checker. Before you commit to a delivery date, see whether stock and people's calendars can meet it.
- Commissions. Calculated from paid invoices, with clawback when a credit note is issued.
- Automation preview. See how often a new rule would have fired last month before you switch it on.
Your data is yours
Nobody can raise your price or lock you out
A company's customers, employees, contracts and books belong to the company — not to whoever hosts the software.
You choose where it lives
Your own server, a machine in your office, a data centre in your country or any cloud you trust. NERP doesn't call home and needs no outside service to run.
Take all of it with you
One click exports every table as CSV and every stored file under its own name, with a checksum manifest, in formats any other tool can read.
Prove nothing was changed
A tamper-evident, hash-chained audit trail signed with a key that isn't in the database.
Control who sees what
Roles and permissions down to individual CRM fields, single sign-on (LDAP, SAML, OpenID Connect), two-factor sign-in and encrypted file storage.
Privacy built in
Personal data requests — access reports and reviewed erasure — answered from one page, and retention rules per kind of data, applied nightly.
Safe to change, easy to restore
Verified backups with point-in-time restore, a health page with alerts, and an anonymised sandbox for trying changes before they go live.
What per-seat pricing costs you
Stop paying rent on your own records
Hosted suites usually charge per user, per month, forever — and the bill grows with every hire. Enter your own numbers to see what that adds up to.
Technology
Built to run for years with few people to look after it
Rust
Axum, sqlx and Tokio in one compiled binary. No runtime to install or patch, low memory use, steady performance on modest hardware. Upgrading is replacing one file.
PostgreSQL
One mature, free database for everything — transactions across modules, full-text search, JSON, streamed point-in-time recovery and replication.
Svelte 5
A SvelteKit web app with small, fast pages that work on ordinary laptops and phones, served by NERP itself.
Self-hosted services
Typst for documents, Collabora for office editing, LiveKit for video calls and your own mail server. Nothing depends on a third-party cloud.
Tested like it matters
Every feature ships with API and browser tests against a real server and database, plus a security suite of tens of thousands of checks against every route.
Redis only as a cache
Sessions and everything that matters live in PostgreSQL. Losing the cache loses nothing.
Pricing
Free software. Help when you want it.
You pay for help, not for permission to use your own system — and you're free to do it yourself or hire anyone else.

Questions
Frequently asked
Is NERP really free?
Yes. NERP is licensed under the GNU GPL v3. There is no licence fee, no per-user price and no paid edition with features held back. You pay only for the hardware or hosting you run it on, and for support if you choose to buy it.
What do I need to run it?
A Linux server with PostgreSQL and Redis. NERP is one server binary that also serves the web app; database migrations run on start. Collabora (office editing) and LiveKit (video calls) are optional and self-hosted. The setup guide covers it step by step.
Can I move my data from another CRM?
Yes. NERP imports contacts, companies, deals and more from other CRMs' exports and from CSV, and catches duplicates as it goes. Nalanda Labs can do the migration for you.
Can I get my data out again?
At any time. The company export writes every table as CSV and every file under its own name, with checksums, in a single archive any other tool can read.
Is there a mobile app?
The web app works on phones today. Native mobile and desktop apps are planned next and will live in their own repositories; the server side they need is already in NERP.
What isn't included yet?
SMS delivery, telephony, card payments and AI features, which depend on a provider each company chooses. NERP uses PostgreSQL only, by design.
Can I change the code?
Yes — read it, change it and share your changes. Under the GPL, anything you distribute stays under the same licence, so nobody can turn NERP into a closed product.
