One trip, start to finish

N551HK flew the owner from Teterboro to Palm Beach and back. Here is its paperwork, from the first fuel ticket to the invoice.

  1. Teterboro, 8 July

    Snap the fuel ticket

    Photograph a receipt in the iOS app, drop it on the web, or forward it to your account's email address. HangarKeep reads the vendor, gallons, line items, tail number, and airport, then waits for you to check them.

  2. Palm Beach, 12 July

    Every cost lands on the trip

    Each expense carries its aircraft, trip, airport, and who it's billable to, with fuel split from fees. Foreign-currency receipts convert at that day's rate. The trip report above builds itself from these.

  3. Invoiced, 14 July

    Bill the owner

    Pick the billable expenses and HangarKeep builds the invoice, itemized the way your client expects. Email it as a PDF, and billed expenses lock so the numbers can't drift after it goes out.
