About InvoiceKoi
InvoiceKoi helps electricians, plumbers, builders and small trade businesses create invoices, estimates and receipts from their phone. Core invoicing works offline without an account. Save clients and prices, share PDFs, track time and review reports. AI voice-to-invoice turns spoken job details into draft invoices, and receipt scanning captures expenses. Android is available on Google Play; the iPhone app is in App Store review. Setup and drafts are free. Issuing documents requires a subscription at US$99.99/year or US$9.99/week, with local store prices varying. AI features, cloud backups and payment collection need internet. Built by Fang in Singapore.
