Problems we solve
Every feature in oRRbit exists because a real business owner asked for it.
Manual billing is time-consuming and prone to calculation errors.
With oRRbit™ GST Billing Software, you can easily generate sales bills, purchase bills, estimates, and detailed invoices. It makes the billing process fast, clean, and professional.
Creating invoices and tax reports can be confusing.
The software provides GST-compliant sale/purchase invoices, a Sale GST Register, a Purchase GST Register, and a Tax Summary Report, making it easy to maintain GST records.
An exact record of the stock is not maintained.
Stock records and stock reports help business owners understand their real-time stock position.
Expired products lead to losses.
Through Product Expiry Records, Expiry Alerts and Expiry Report, timely record of near-expiry products is available, which makes stock rotation and loss control easy.
Losses from Damgarh products are not tracked.
Proper entry, analysis, and profit impact tracking of damaged goods can be carried out using damaged product records and damage reports.
Follow-ups for pending payments from customers get missed.
Outstanding amounts can be easily monitored using outstanding dues tracking, payment due notifications, and outstanding analysis reports.
