What is InvoiceKoi?
InvoiceKoi is an Android invoicing app for tradespeople, sole traders and small businesses. It brings invoice, estimate and receipt drafting into a phone workflow, so the person doing the work can prepare a document between jobs. AI voice drafts and receipt reading help prepare information for review while the user checks the document details.
The core drafting workflow works offline without an account. Saved clients, rates, records and totals are part of that offline workflow. This makes the core tools useful when a job takes place somewhere with a weak signal. Users can prepare drafts and work with their saved records without first setting up an account.
AI features need internet. Cloud backup, purchase verification and payment collection also need internet. Before issuing a document, the user should check the customer, line items, amounts and payment details. The app is aimed at people who need to prepare invoices, estimates and receipts from an Android phone, with clear boundaries between offline core functions and features that connect to online services.
Drafting is free. Issuing, sharing or printing new numbered invoices, estimates and receipts requires a subscription. Local prices and any eligible offers are shown in Google Play. Existing issued records remain available after a subscription expires for viewing and export, resending issued invoices and collecting outstanding payments. The separate browser generator described below has its own free scope.
InvoiceKoi's public website also provides a free browser invoice generator. It needs no account or email sign-up, adds no watermark and has no invoice limit. Users enter their business and client information, line items, dates, manual payment instructions and an optional logo, then review the live invoice preview. PDF output uses the browser's print dialog. The browser tool prepares printable documents with payment instructions entered by the user. Invoice information entered into this browser generator stays in the browser.
