TASNI ERP · powered by BillingEngine 3.0

Billing, stock, GST & accounts — one system for every counter.

TASNI ERP runs your shop from one server: fast GST billing at every counter, live stock across shops and godowns, Tally-ready books, payroll, and a daily report on the owner's WhatsApp. It works on the shop PC even when the internet is down — or in the cloud when you have branches.

How it fits together

One server. Every counter in sync.

All data lives in one PostgreSQL database on the shop server (or a cloud VPS). Every PC, browser and phone is a window into the same books — two counters can never silently overwrite each other.

TASNI ERP architecture Desktop app, browser and Android phones connect to the TASNI ERP server running Node.js and PostgreSQL. The server sends backups to Google Drive and USB, exports to Tally, sends the daily owner report on WhatsApp and e-mail, and answers Alexa.

  • Two counters saving the same record? The second is told to refresh — never a silent overwrite
  • One-click restore — the current data is always saved first
  • Licensed per installation by TASNI

TASNI ERP — questions

Does it work without internet?

Yes. With the shop-PC server, every counter and phone on the shop network keeps billing when the internet is down. Internet is needed only for the Google Drive backup copy, the WhatsApp report and remote access.

Can my accountant use Tally?

Yes. TASNI ERP keeps Tally-style ledgers and vouchers and exports a TallyPrime XML file, so your CA can import your books directly.

I'm on the composition scheme. Is there a version for me?

Yes — TASNI ERP comes as a Regular GST edition and a separate Composition edition, so your bills always print in the right format.

How many counters and users can I have?

Several counters, PCs and phones work on the same data at once. The number of users is set in your licence — tell us your shop size and we'll quote.

Can I move my old data in?

Items, customers and opening stock can be imported from Excel. Talk to us about your current software and we'll plan the move.

See TASNI ERP on your own stock.

Send us a few of your items and bills — we'll show you a live demo with your data, and an installation plan for your shop.

TASNI Water · Mobile app + Smart Water Sensor

Your water tank, live on your phone.

The TASNI Water sensor measures your overhead tank; the TASNI Water app shows the level, litres and daily usage, and alerts you before it runs dry — or overflows at 2 am when municipal water arrives. No more climbing the terrace to check.

Why it matters

Built around Indian water reality.

Irregular municipal supply

Water comes on alternate days, at odd hours. See exactly how much is left and how fast you're using it — plan before it runs out.

No more terrace climbing

Stop sending family members up slippery stairs and onto tank lids to check the level — especially elders and children.

Overnight overflow

Supply at 2 am with the motor running? Level milestones and direction alerts tell you when it's nearly full — with quiet hours for when you don't want to be woken.

How it works

Sensor to phone in seconds.

Ultrasonic sensor+ temperature probe ESP32TASNI controllerfilters every reading MQTT serviceTLS · primary + backup 72%TASNI app

Features

Small device. Serious engineering.

Heat-corrected readings

Sound travels faster in a hot tank. A temperature probe corrects every reading, so Telangana summers don't cause phantom level jumps.

Noise-filtered levels

Many samples per reading, with outlier rejection tuned across the full 0–100% range — steady numbers, not flicker.

Alerts your way

Level milestones, filling / emptying direction, reminder intervals, set daily times, quiet hours and your choice of notification sound.

History & Excel report

About 31 days of history on the phone, daily usage totals, and a one-tap Excel report saved to your Downloads.

Two cloud paths

The device publishes to a primary and a backup MQTT service over TLS, and also serves a local dashboard on your Wi-Fi.

Pump control module

Protect the motor from running dry.

Our pump controller switches the motor through its starter and watches the tank. If the level doesn't rise after the pump starts, it raises a dry-run alarm on the display and buzzer — so the motor isn't left burning with no water in the line.

  • Three-layer check: minimum run window, rise threshold and a 3-of-4 vote — no false trips from one bad reading
  • Display alarm screens and distinct buzzer patterns per alarm
  • Wired for common single-phase starter boxes
  • Alarm stays latched until a person clears it — no surprise restarts

WhatsApp Doctor Appointment System

Patients book the doctor right on WhatsApp.

Your clinic's WhatsApp number becomes a booking desk that never closes. Patients send "Hi", choose the doctor, date and time, and get a confirmation in the same chat — no app to download, no phone call, no waiting on hold.

Works on any phone with WhatsApp Books 24 × 7 Fewer calls at the front desk

Why WhatsApp

Your patients are already there.

Almost every patient in India uses WhatsApp every day. Booking where they already chat is easier than any website form or app.

Nothing to install

Patients use the WhatsApp they already have — young or old, any phone.

Open after hours

Bookings come in at night and on Sundays, when nobody is at the desk to answer the phone.

Fewer phone calls

Your receptionist spends time on patients in the clinic, not on "is the doctor free tomorrow?"

No double booking

Patients only see the time slots that are still free for that doctor and day.

How it works

Four steps. One chat.

Privacy & data choices

Effective / updated: 30 October 2026 · Notice version 2026-10-30.4

QR pairing · MQTT service · India’s DPDP framework

Who is responsible

TASNI Trading Private Limited, Telangana, India, provides TASNI Water. For personal data whose purposes and means TASNI determines, TASNI acts as the Data Fiduciary. Privacy and grievance contact: TASNI Privacy Contact, sales@tasni.in, +91 81795 04141. Website: www.tasni.in. This notice covers the Android app, sensor pairing and the monitoring service. An installer or other broker operator may have separate responsibilities for processing it controls.

India’s DPDP framework

This policy is framed with reference to the Digital Personal Data Protection Act, 2023 and the Digital Personal Data Protection Rules, 2025, as amended and applicable. Their provisions have phased commencement dates; statutory obligations and rights apply according to the notified commencement and any applicable exemption. The notice, choice and withdrawal controls described here are available in the current TASNI Water Android app. This policy does not itself certify the service or replace the operational safeguards required by law.

What information is used and why

InformationPurpose and destination
Device ID, tank label, signed QR viewing credential and broker addressPair your sensor and authenticate to the selected MQTT service. Saved in private app storage; the broker receives authentication and topic/subscription information.
Water level, distance, volume/capacity, usage, device status, firmware version, connection quality and sensor IP, when published by the sensorDisplay the tank, history and selected alerts. Received from your sensor through the broker or a local network connection.
Connection IP address, connection timing and subscription/authentication eventsDeliver and protect broker communications. Processed by the configured broker and its hosting/network providers.
Optional sensor IP/dashboard password and Wi-Fi name/password you enter for setupContact or configure your sensor on your private network. Wi-Fi credentials are sent directly to the verified sensor so it can join that Wi-Fi; the app does not save the home Wi-Fi password. Nearby home Wi-Fi names are listed on the phone during setup and are not uploaded to the MQTT service. The app filters out temporary TASNI setup networks from that customer list.
Alert preferences, saved history, notice version, consent time and adult/self-consent confirmationRemember your choices and demonstrate the choice on this phone. These records are local to the app; they are not a central customer-consent database.
Contact details and device/installation information you voluntarily send to TASNI for support or a privacy requestVerify your authority, provide support and respond to the request. Your email/telephone provider also handles the communication.

The app requires no account or phone-number registration and contains no advertisements or advertising analytics SDK. It does not read contacts, SMS or precise GPS coordinates. Avoid putting unnecessary personal information in a tank label.

Excel reports and notification choices

You can save an Excel usage report from Water history. It contains the available daily totals and readings, tank label/device ID, capacity and reporting times. It does not contain Wi-Fi/dashboard passwords, MQTT login details or service addresses. On Android 10 and later it is saved to Downloads/TASNI_Water; older Android versions ask you to choose a save folder. The app does not upload this report. Files you export remain in Downloads or the selected folder after app data is removed, consent is withdrawn or the app is uninstalled; delete exported copies yourself and share them only with people you choose. Level milestones, direction, reminder interval, chosen daily times and quiet hours are stored locally as notification preferences. With regular reminders enabled and no daily times selected, the default is once every three hours while fresh readings are available. Background delivery requires your optional monitoring choice and Android permissions; device settings may delay delivery.

MQTT service

Remote monitoring uses the configured MQTT service supplied for your device. TASNI may provide it through an authorised service/hosting provider, its own VPS or an in-house server. The broker handles the data needed for authentication, subscriptions, delivery and service security. A signed sticker identifies the configured broker. Updating this policy does not move your device to another broker. Hosting location depends on the configured service and may be outside India; contact TASNI for the deployment’s operator and hosting region. Transfers and disclosures remain subject to applicable Indian law and notified restrictions.

Your notice, consent and separate choices

Before the app starts real tank connections, the Android app asks you to read a purpose-specific notice and make an affirmative, unticked choice. It records the notice version, time and adult/self-consent confirmation on the phone and checks the notice version before native background monitoring can start. You may decline and use the offline demo without connecting to a real broker. Previously paired users must make this choice for the new notice before app connections resume. Permission for QR-camera scanning, Wi-Fi setup and background notifications is requested separately when used; optional background monitoring starts only when enabled in Alerts. A new or unrelated purpose requires a new notice/appropriate permission rather than automatic reuse of this choice. Contact TASNI if you need this notice in an Indian language you can understand.

Withdraw consent and remove app data

In the app, open Settings → Privacy & data → Withdraw consent & remove app data and confirm. The app stops its live connections and background monitoring and removes its saved pairings/credentials, history, alert records, consent receipt and native monitoring data. You can also use Settings → Remove all app data, or Android’s Clear storage. Removing one tank clears that tank’s app history and alert records. Withdrawing the app choice prevents app connections until you choose again. A separately powered sensor may keep publishing. To withdraw processing by TASNI beyond this phone, disable the sensor’s MQTT publishing or contact the TASNI Privacy Contact to revoke service access and handle device/broker records. Local deletion does not remotely erase broker logs or factory-reset the sensor. Records required by applicable law may be retained for that purpose; TASNI will explain any applicable exception.

Access, correction, erasure and nomination

Contact sales@tasni.in with “TASNI Water privacy request” and the device ID or installation reference. You may request information about your personal data processing and recipients, correction/update, erasure, or nomination of a person to exercise applicable rights in the event of death or incapacity. Saved tank names/settings can also be corrected within the app. TASNI may seek reasonable, proportionate proof that you are entitled to act for the device/data; do not send passwords, Aadhaar or other identity documents unless a necessary, secure process has been explained. Requests are handled through TASNI’s privacy process; the app does not automatically submit them or erase remote records. Statutory rights are subject to their commencement, scope and legal exceptions.

Grievances and escalation

Send a grievance to the TASNI Privacy Contact at sales@tasni.in or call +91 81795 04141. Include the affected device/reference, the concern and a safe reply contact. TASNI’s grievance response window is within 90 days. Use TASNI’s grievance mechanism first. If the matter remains unresolved, you may approach the Data Protection Board of India through its officially published procedure when the relevant provisions apply. Do not publish credentials or another person’s personal data in a complaint.

Storage, retention and deletion

Phone records stay until removed, app storage is cleared or the app is uninstalled; recorded history uses a rolling window of about 31 days while readings are recorded, and alerts use bounded lists. Older stored history may remain until subsequent recording trims it or you delete it. App backup is disabled. Sensor configuration/history, vendor installation records, support communications, MQTT retained messages and broker/security logs have separate storage lifecycles. TASNI must keep only what is needed for the stated purpose or applicable legal retention, restrict retained records to that purpose and arrange erasure with processors when appropriate. Applicable DPDP Rules may require specified processing/security records to be kept for at least one year after their relevant commencement, or longer where another law requires it. A deletion request is assessed against the records actually held and any applicable retention duty; you will be told the reason for a lawful retention exception.

Security and disclosures

Internet MQTT connections in the app use TLS. The app checks TASNI QR signatures and checks the approved firmware signature/hash before sending an update. App records use Android private app storage and are not advertised as an independent encrypted vault. Local sensor HTTP is unencrypted; use only a trusted private Wi-Fi or the sensor’s setup network, protect dashboard/Wi-Fi credentials, and avoid exposing the sensor to the public internet. A QR signature verifies its issuer; it does not encrypt the viewing credential. Anyone with a copy may view the tank if the broker allows it. Keep stickers private and contact TASNI for credential rotation. Information is disclosed to configured sensor/broker, hosting/network or support providers as needed for the service, or when lawfully required. TASNI does not sell app data or use it for advertising. Processor arrangements, access controls, security monitoring, retention and incident response must be maintained for the actual deployment.

Camera, nearby Wi-Fi and notifications

Camera access is optional and decodes stickers on the phone; camera images are not uploaded by this app. The optional phone Wi-Fi list requires Android location permission and Location enabled; this is used to list home network names, not to read GPS coordinates. Nearby Wi-Fi permission on supported Android versions is requested later when a temporary sensor connection is needed to send Wi-Fi settings. Network names and scan details are not uploaded to the MQTT service. The app does not request background location. Manual Wi-Fi-name entry remains available if listing permission is declined or listing is unavailable; manual signed-code entry remains an alternative to the camera. Background monitoring is optional and displays a visible foreground-service notification with Stop monitoring. Stop also pauses monitoring until you explicitly enable it again. Android permissions, network availability, power management and force-stop affect delivery. Notification sounds can be changed from Alerts → Choose notification sound on supported Android versions. This is a monitoring aid; independent overflow and electrical protection remain necessary.

Adults and lawful guardians

The current live-monitoring app flow is for people aged 18 or older who can consent for themselves. It asks for an adult/self-consent confirmation without collecting a birth date or identity document. This is a self-declaration, not verified parental or guardian consent. Processing for a child, or for a person who requires a lawful guardian to consent, is not supported by the current automated flow. Contact TASNI before proceeding so that any required verified consent and authority can be addressed through an appropriate separate process. The app does not use behavioural advertising or track children.

Incidents, changes and this webpage

Report suspected unauthorised access or a data breach promptly to sales@tasni.in. TASNI’s incident process must assess the event, contain access, protect affected people and make legally required notices to affected individuals and the Board within applicable timelines. Policy changes are published here with a revised date; material new purposes require appropriate new notice/consent. This standalone privacy page contains no advertising, analytics, external-font or tracking scripts. The web host may process ordinary request/security logs. When inserted in www.tasni.in, that site’s own plugins, cookies and hosting may add separate processing covered by the website’s notices.

Website privacy — www.tasni.in

Website notice updated: 30 October 2026. This section covers the TASNI company website separately from the TASNI Water app notice above. The responsible company and privacy contact are the same.

Visiting the website

The website host may process your IP address, browser request details, requested pages, timestamps and security logs to deliver the website, prevent misuse and investigate errors. The company homepage loads interface libraries, icons and fonts from external content-delivery services, including Tailwind’s CDN, CDNJS and Google Fonts. Requests to those services can disclose your connection IP and ordinary browser request information to their operators. Their processing also follows their own published privacy terms. This standalone privacy page uses local styling and loads no external fonts, analytics or advertising scripts.

Enquiries and the contact-form preview

If you email or call TASNI, we use the name, reply contact, enquiry and installation details you choose to provide to answer your request, provide a quotation or support, and maintain necessary business records. Your chosen email or telephone provider also handles that communication. Share only what is needed; do not send Wi-Fi, dashboard or MQTT passwords in an ordinary enquiry.

The website contact form is a demonstration and does not send its entered fields to TASNI. Use the email or telephone links to contact us. The interactive website dashboard shows simulated sample data and does not connect to a customer’s tank.

Choices and website records

This website adds no sign-in service, advertising analytics, behavioural profiling, account registration or marketing subscription. Third-party assets and hosting can have their own logging or cookie practices; this notice does not promise that other providers process no data. If TASNI later adds a contact-form backend, advertising, analytics or another new purpose, the website notice and any applicable choice or consent controls must be updated before that processing starts.

To request access, correction, erasure or help with a website enquiry record, email sales@tasni.in with a safe reference and reply contact. Retention must be limited to the relevant service/business purpose and applicable legal requirements; a website request does not automatically erase records held independently by your communications provider. The DPDP commencement, rights, grievance and security explanations above apply according to the law’s scope and effective dates.
