Billing Fast is billing software for Kenyan retailers, restaurants, and service businesses in Nairobi, Mombasa, Kisumu, Nakuru, and across the country. It produces VAT-ready invoices at 16%, prints your KRA PIN and business details on each bill, and totals the tax automatically, so invoices are clear for customers and for your records. Bill in Kenyan shillings (KES), record M-Pesa, cash, or card payments, manage inventory with low-stock alerts, scan barcodes, and send invoices on WhatsApp. Keep a customer ledger for buyers who pay on account, and run several outlets from one cloud account. It works on Android, tablet, and desktop and syncs in real time, so a duka in Nairobi or a shop in Mombasa can bill fast from any device. Billing Fast is free to start — create up to 10 bills free, then choose an affordable annual plan. For KRA e-invoicing rules such as eTIMS, check the latest official KRA guidance.
