Why SchoolOS
Built around the jobs your front desk actually does.
Attendance that closes itself
Sessions auto-generate from the weekly timetable. Substitutes are one tap. Missed days are marked. The monthly report is always one screen away.
Fees with real billing logic
Monthly, quarterly, annual, or one-time. Subscription or installment. Discounts that apply to one student, one fee, or the whole course. No spreadsheet gymnastics.
Receipts, on demand
Every paid invoice gets a downloadable PDF receipt. No "send me the receipt over WhatsApp" loops.
Role-based access, done right
Owners, admins, accountants, teachers, students. Per-course, per-section, per-feature. A teacher doesn't see fees; an accountant doesn't grant attendance.
Audit trail and trash recovery
Every important change is logged. Deleted courses, fees, and discounts are recoverable with one tap from the admin Trash screen.
Announcements that hit the right people
Post to the whole institute, a single course, or just one section. No more 6 WhatsApp groups for the same notice.
Why KharchaOS
Your own spending, and the money between friends — in one place.
Every rupee, in the right account
Log expenses, income and transfers against the account they actually came from — bank, cash, UPI wallet or card. Balances update as you go, so the app matches your real world instead of drifting from it.
Budgets that tell you early
Set a monthly budget per category and see what's left at a glance — not after the month closes. The home screen answers "can I spend this?" before you spend it.
Split a bill without the awkward part
Create a group for a trip, a flat, or a dinner. Add who paid and how it splits, and everyone sees the same running balance. Settling up is one tap, and the other person confirms it — so no one's records quietly disagree.
Lending you can actually point to
Record money you lent or borrowed and the other person confirms it, so both sides hold the same number. Repayments update both copies. It stays a shared record, not a note only one of you kept.
Add people the way you already reach them
Phone number, email, or a shareable invite code. They don't need the app for you to track what they owe — and if they join later, the record links up instead of starting over.
See where it actually went
Spending trends and a category breakdown for today, this week, this month, this year — or any date range you pick. Enough to spot the pattern without turning it into homework.
Private by default
No bank connection. No ads. No selling your data.
KharchaOS never links to your bank, reads your SMS, or touches your device contacts — the numbers are the ones you enter. It shows no ads and we don't sell or profile your data. Read the KharchaOS Privacy Notice.

Platform approach
Small products, built on serious backend foundations.
Every Singnet product ships on the same secure core. As we add new modules, your existing admin and audit setup carries over — no fresh integration each time.
Clear workflow boundaries
Products are shaped around daily jobs: attendance closure, billing review, access approval, receipt issuance.
Secure API core
JWT auth with refresh, role-and-scope checks, audit logging, rate limits, idempotency keys, soft-deletes on financial data.
Practical growth path
Each new product shares the same deployment, observability and security discipline. No new vendor for the next module.
Common questions
Things institute owners ask before signing up.
How long does setup take?
Most institutes are up and running in 15–30 minutes — create your enterprise, add your sessions, import students, and you're live. We can help on a call if you're nervous about the first run.
Can I import students from Excel?
Bulk CSV import lands in Premium soon. Until then we'll do a one-time import for you free during onboarding.
Where is my data hosted?
Singapore region for low latency to India. Daily encrypted backups to Backblaze with 30-day retention. Your data is yours — full export anytime.
Does it work offline?
The Android app caches read data for offline browsing. Writes (marking attendance, recording payments) need a connection. Offline write queue is on the roadmap.
Can I switch tiers?
Yes — upgrade or downgrade any time from your account. Pro-rated for the rest of the billing cycle.
What about WhatsApp / SMS to parents?
WhatsApp notifications are part of Premium. SMS fallback is metered (₹0.20 per SMS, charged separately).
Is singnet.in affiliated with SingNet or Singtel?
No. singnet.in is an independent platform and is not affiliated with, endorsed by, or connected to SingNet Pte Ltd, Singtel, or Singnet Software Solutions Pvt Ltd.
