SkyBid
Measure roofs, walls, flatwork and fences from public-domain aerial imagery, your own drone photo or a quick sketch. Price from your own price book, every number traced, and get the proposal signed on screen.
Title search, a chain-of-title canvas, commitment requirements, contract deadlines, net sheets, earnest money and escrow ledgers, in one program that checks every file as you work.
Consents, signed notes, scored measures, ICD-10-CM codes, treatment plans and billing in one app. It runs on your own computer, even offline, and checks every chart as you go.
Cost every recipe from your real invoice prices, see which dishes earn their spot, compare theoretical to actual food cost, and keep food-safety records off the clipboard.
Build complete websites and one-screen phone apps for your clients, export files they own, and print the QR and NFC card sheets. One license covers every site or app you build.
Learn it, practice it with paper trading on real prices, then trade your own accounts with you confirming every order.
Self-directed software, not a broker-dealer or investment adviser. Not investment advice.

GridSpan
A utility operations system for municipal, co-op and multi-service utilities, made generic from a system built for a public power utility. We mention it to show the range of what we build; it isn't offered for sale.
