About this app

Keystone is the all-in-one business management app for solo and small-team service professionals — plumbers, electricians, cleaners, landscapers, handymen, mobile detailers, daycare operators, pet sitters, photographers, and 20+ other trades. Manage clients, schedule jobs, send invoices and estimates, collect payments, and see your whole business at a glance — all from your phone, without juggling five different apps.

EVERY CLIENT, ONE PLACE
Full contact info, service and property details, job history, invoices, and messages — no more digging through texts and spreadsheets to remember who owes what. Attach photos and notes to every job (before/after shots, receipts, equipment issues) so nothing gets lost between visits.

SCHEDULE SMARTER, NOT HARDER
Book one-off jobs or set up recurring work that repeats itself. See your day mapped and optimized so you're not backtracking across town, and check in and out of job sites with a tap. Get push notifications the moment something changes.

GET PAID FASTER
Turn an accepted estimate into an invoice in one tap. Send professional invoices your clients can pay instantly from their phone via Square or Stripe — no more chasing checks. Give clients their own self-serve portal to view invoices, see upcoming appointments, and message you directly, so routine questions stop turning into phone calls.

KNOW YOUR NUMBERS AT TAX TIME
Log mileage and expenses as you go, categorized to match Schedule C, with IRS-rate mileage deductions calculated automatically. Export a clean tax report instead of reconstructing a year of receipts every April.

SEE YOUR BUSINESS AT A GLANCE
A real dashboard — today's jobs, revenue, what's outstanding — not a wall of spreadsheet tabs. Deeper analytics and reporting available on Pro.

BUILT TO FIT YOUR TRADE
Keystone adapts its features to 28 different service business types — a daycare gets child care logs and incident reports; a landscaper gets route planning; a rental business gets booking calendars. You're not stuck with generic CRM fields that don't match how your business actually runs.

SECURE BY DEFAULT
Lock the app behind biometric. Your data syncs across your
devices and works offline when you don't have signal — nothing gets lost, it just syncs when you're back online.

What’s new

Clients of your business now use Keystone completely free, with no upgrade prompts.

Check-in, check-out and schedule times now show in your local time zone, and parents get a notification when their child is checked out.

Draft invoices and estimates stay hidden from clients until you send them, and a failed payment-link attempt no longer leaves a processing fee on your invoice.
