FAQ
What is NIRU?
NIRU is an accounting and CRM platform. It combines double-entry bookkeeping, invoicing, sales, purchases, payments, customer management and reporting in one web application.
Does NIRU support e-invoicing?
Yes. Invoices can be printed, exported to PDF and shared by email or WhatsApp, and the platform supports e-invoice workflows.
Are my books separated by financial year?
Yes. Books are organised year by year, so each financial year stays clean while you can still move between years.
Can I control who sees what?
Yes. Role-based permissions control access to each module and action, so teams only see what their role needs.
Can I export my data?
Lists and reports can be exported to CSV or PDF, so your data is never locked in.
Can I scan barcodes while billing?
Yes. On a sales or purchase invoice you can scan with a USB or Bluetooth scanner gun, with the device camera in the browser, or type the code. Scanning the same product again increases its quantity. Camera scanning needs a secure (HTTPS) connection, and NIRU runs in the browser rather than as a native mobile app.
Does NIRU track product warranties and service visits?
Yes. Set a warranty period on the product, add the serial number on the invoice line, and NIRU saves a customer product record with the warranty end date and its Active or Expired status. Service visits are recorded as service invoices linked to the customer’s machine, so each customer has a service history.
Can one invoice be paid with Cash, UPI and Bank together?
Yes, by recording a receipt for each mode and allocating each to the same invoice; NIRU recalculates the outstanding balance across all of them. A single entry that splits one payment across several modes is not available. When you collect payment while saving an invoice, one mode (Cash, Bank or UPI) settles the full outstanding. The Finance mode is coming soon.
Can one receipt settle several invoices?
Yes. A receipt or payment voucher belongs to one party and can be allocated across that party’s open invoices with partial amounts. The voucher posts to the ledger once; allocation only links it to the invoices.
How much does NIRU cost?
Pricing depends on your business size and modules. Contact us for a quote — we publish only confirmed pricing.
