A PRACTICAL BUSINESS WORKFLOW
A bill should update more than a PDF
Creating an invoice is only one part of a sale. The transaction may also change stock, customer outstanding, payment account, salesperson commission and business reports. Re-entering the same sale into multiple registers wastes time and increases the chance of mismatched numbers.
Olo Book connects GST and non-GST billing with purchases, inventory, parties and payments. Businesses can create sales, purchase entries, estimates and delivery challans from an Android phone. Product and service workflows are handled appropriately, so a service does not need artificial stock quantity.
For product businesses, purchase and sale movement contributes to item history and stock visibility. For serialized products, IMEI or serial tracking provides a more accountable path from inward purchase to customer sale.
