What tools do you rely on to run a pet‑sitting / dog‑walking business?

If you run or work for a pet‑care service, share the real tools you use for day‑to‑day ops: scheduling, recurring bookings, payments, client & pet records, messaging, and staff calendars. Please be concrete — name the app(s), rough monthly cost, which features you actually use, and any integrations that matter (Stripe, QuickBooks, Google Calendar, Zapier, etc.).

A few specific things that are most useful to hear about:
- How well the mobile app works for sitters (offline access, notifications, check‑ins).
- Handling deposits/refunds and recurring bookings.
- Staff scheduling vs. client booking flow (do clients book staff directly?).
- Must‑have integrations and bookkeeping flow (Stripe vs Square, QuickBooks sync).
- Dealbreakers or things that caused you to switch vendors.

Please include your scale/setting (solo proprietor, 2–10 sitters, 10+ sitters, agency) and your region (country) so recommendations are relevant. If you’re willing, use this quick reply format to make responses easier to scan:
