## What is CogniBill?

Turn a job description into a customer-ready estimate.

CogniBill helps solo contractors, tradespeople, and freelancers move from a customer request to a polished PDF without wrestling with spreadsheets or heavyweight accounting software.

DESCRIBE IT. REVIEW IT. SEND IT.

Tell CogniBill what the customer needs in your own words. AI can organize the customer, job title, line items, quantities, and rates into an editable draft. Review every detail, make changes, and create the document when it is ready.

Choose Apple Intelligence on supported devices, or connect your own OpenAI-compatible API service. Compatible services may include providers such as DeepSeek, depending on the endpoint and model you configure. Third-party AI use requires your own service credentials and may be subject to that provider's terms and charges.

PROFESSIONAL PDFS, READY TO GO

- Create estimates and invoices with your business details and logo
- Add tax, deposits, terms, payment instructions, and a signature
- Preview a clean, customer-ready PDF
- Share through the iOS share sheet using Messages, Mail, AirDrop, WhatsApp, or other installed apps
- Print a paper copy when the customer or job site needs one

FROM QUOTE TO PAID

- Convert an accepted estimate into an invoice
- Record deposits, partial payments, and final payments
- See paid amounts and the remaining balance at a glance
- Keep customers, projects, documents, and payment history together
- Review business activity and export reports to Excel-compatible files

BUILT FOR INDEPENDENT WORK

CogniBill is useful for HVAC technicians, plumbers, electricians, handymen, remodelers, repair professionals, designers, photographers, tutors, consultants, beauty professionals, and other independent service providers.

LOCAL-FIRST AND STRAIGHTFORWARD

Your core business records are stored locally on your device. Create and manage documents without a connection; online AI services naturally require network access. The free version supports up to 3 new documents per month. A one-time purchase unlocks unlimited documents, all templates, and reports—no recurring subscription.

Important: CogniBill creates business documents and records payment information. It does not process payments, issue government-certified tax documents, or provide legal, accounting, or tax advice. Always review AI-generated content and confirm local requirements before sending a document.
