Keel: invoice app for iOS
Keel is an iOS estimating and invoicing app for trades and people who work for themselves: quote the job, run it as a work order, track job costs, receipts and mileage, send the invoice and see what is owed. Engineered natively in SwiftUI + Rust for self-employed contractors, tradespeople, freelancers, and one-person service businesses who run the business side from their iPhone and iPad.
- 1-Line Gloved-Thumb Dock & Active Job Magnet. Type one line on site — like "Harrington $120 lumber, 18 mi" — and Keel parses the customer, expense and mileage pills automatically, snapping them straight to the active job.
- Keep every job together. Every expense and invoice is a step of a job, and all of it is kept with that job — so you can see what a job cost and what you billed.
- Know your customers. A small CRM built in: each customer’s jobs, invoices and payment history in one place.
- Invoice the customer. Clean PDF invoices with taxes, discounts and payment terms, sent by email, Messages or WhatsApp. Add a payment QR code; line items you have used before are suggested, priced from your own history.
- Keep receipts. Photograph a receipt while it is still in your hand and file it against the customer or the job.
- Track expenses. Every expense recorded with its category and its receipt, under the job it belongs to — so you can see what each job cost.
- Track payments. Every invoice is kept with its job and client, and each payment is recorded against it, so you can see what has been paid.
- See what is actually yours. Freeboard is your cash minus a tax reserve, the bills you have committed to and a buffer you set — the amount you can actually spend or pay yourself. A planning estimate, not tax advice.
- Hand your accountant the year. At filing time, Keel compiles your 5-Folder Statutory Pack — supporting worksheets, mileage logs, income proof, job profitability, and accountant CSVs — built from the books you already keep.
- Prove your income. Applying for a loan, a lease or anything else that asks what you earn? The income package turns your own records into proof a lender can read.
