IndiaBuilt in India, for Indian solar
You shouldn’t have to call five people to know what’s happening.
Leads on WhatsApp. BOQ in Excel. Material updates on a call. Payments in somebody’s head. SORA connects all of it — first enquiry to final payment — and tells you what needs you today, before anybody has to ask.
- Unlimited users, projects & leads
- One plan — everything included
- Your data exports, always
- Works offline on the roof
Six questions, about two minutes, and you see what SORA will fix for you first — and exactly what it costs.

One system for
Unlimited users. Unlimited projects. One flat price.
Add your sales team, site engineers, technicians, store and accounts — everyone gets a login, and your bill never moves because you hired someone.
See it
Design the roof. Win the customer.
The building, the trees beside it and the panels at their tilt — with the real sun for any date.
Automation, end to end
The work moves on its own.
One connected system — leads, proposals, WhatsApp, projects, stock, payments, service. Switch on what you need; everything already talks to everything else.
- 01
New enquiry
Assigned to a salesperson, with a follow-up date, the moment it arrives — from your website, IndiaMART or a form.
- 02
Proposal sent
A quotation leaves on WhatsApp with the design and price, and you see when the customer opens it.
- 03
Customer accepts
The project, the customer account and the payment schedule open themselves. Nobody re-types a thing.
- 04
Material needed
A request from site reaches the store and the manager on their phones, with what is short in stock.
- 05
Payment due
Reminders go out on the due date, and the receipt follows the payment — no awkward calls.
- 06
Crew on site
Check-in reminders before the shift, photos and signatures from the roof, attendance into payroll.
- 07
Purchase orders
Raised against real shortfalls, approved where you want, received against the order.
- 08
After handover
AMC visits scheduled with reminders before they fall due; warranties tracked per plant.
A 20-minute call. We show SORA on a job like yours.
The actual difference
Same facts. One of these you can run a business on.
Today
Pipeline
A WhatsApp thread, 340 messages deep
BOQ
A spreadsheet forked six times this month
Site status
“Bhaiya installation ka kya hua?”
Proof of work
A photo somebody was meant to forward
On SORA
Pipeline
14 leads, staged and scored — nobody re-typed a thing
BOQ
One version, generated from the surveyed roof
Site status
Deshmukh 5.2 kW — installing, 2 of 3 strings done
Proof of work
Photo, signature and location, attached automatically
Nothing on the right is invented data — it is the same four facts on the left, reached the moment they happen instead of the moment somebody remembers to ask.
The platform
The whole business, not a CRM with a solar skin
Every part reads from the one before it, so a number is typed once — at the roof — and carried through to the invoice.
Leads and CRM
Every enquiry scored, staged and followed up — with the next step written on it, so nothing goes cold in a chat thread.
Design on the real roof
Lay panels on the satellite image in 2D and 3D, mark the water tank and the parapet, and see the shadow on the longest and the shortest day of the year.
Quotation and BOQ
Photograph the electricity bill, size the system, and send a branded proposal from your own rates the same afternoon.
Projects and quality
Each stage has a named owner. Installation is checked by a second person, never the installer.
Inventory and material requests
Material is requested against a project and checked against the store before the crew leaves. Purchase orders and vendors come with the Procurement add-on.
Invoices and payments
GST invoices on the milestone, an advance where you take one, reminders on WhatsApp, receipts back by themselves.
Attendance and payroll
Punch in from site, and a payroll run that already follows PF, ESI and professional tax.
Service and AMC
With the Asset, Warranty & AMC add-on, every handed-over plant becomes an asset with its warranty, its AMC schedule and its service history.
One job, start to finish
Every step hands over to the next by itself
This is one real sequence, not ten features. Follow a 5.4 kW rooftop from the enquiry to the last rupee — and watch the thread draw itself as it goes.
Ten stages. Four people. Nobody rang anybody to ask what had happened.
- EnquiryPatil Residence
Came in on WhatsApp at 8:40pm. Logged, scored, assigned to Nilesh before morning.
- SurveyGanesh, on site
Roof drawn on the map, bill photographed, shading noted. No measurements re-typed later.
- Design5.4 kW, 12 panels
Sized from the roof and the bill. BOQ built from your own rates, not a generic template.
- QuotationQT-0042 sent
Priced, branded, and on the customer’s phone the same afternoon — with the PDF attached.
- AcceptedSigned on the portal
Project created automatically. Nobody opened a spreadsheet to start it.
- MaterialRequested and approved
Checked against the store. Short by 40m of DC cable — flagged before the crew left.
- InstallationSagar and Imran
Task on their phones that morning. Photos, serial numbers and a signature from the roof.
- QualityChecked by a second person
Never the installer. Failed earthing raises a defect with an owner and a date.
- HandoverSigned, warranty recorded
Asset created, AMC scheduled, documents in the customer’s portal.
- Payment₹1,62,000 collected
Invoice raised on the milestone. Reminder sent on WhatsApp. Receipt back automatically.
The arithmetic nobody runs
Disorganisation is not free. It is just never invoiced.
Put your own numbers in. Nothing is sent anywhere until you choose to continue.
- That is roughly
- ₹3.36 Cr a year
Leaking out of a year, on these assumptions
₹40.32 L
- Deals lost to a slow quotation₹20.16 L
6% of pipeline value — a quote that takes three days against a competitor who sent one the same evening.
- Enquiries nobody followed up₹13.44 L
4% — leads that went cold in a WhatsApp thread while somebody was on site.
- Material issued but never accounted for₹6.72 L
2% of project value — stock that left the warehouse without a signature against it.
An estimate, not a measurement — the percentages above are stated so you can disagree with them. Halve every one and the number is still worth a morning.
For the owner
Stop managing your business through phone calls
SORA does not show you everything. It shows you the handful of things that will cost you money if nobody touches them today.

For the team
Your fitters don’t need to learn an ERP
They open the app and see today. Three taps and the job is recorded — with photos, a location and a signature, from the roof, offline if the signal is gone.

Your customers
Stop answering “what is my project status?” ten times a day
Your customer gets a WhatsApp from your company, with your name on it, and a link to a page carrying your logo. They can see where their job has reached, read their quotation, open their invoice and pay it — without ringing your office.
SORA runs underneath. The only mention of us is one small line at the bottom. Updates on WhatsApp come with the WhatsApp add-on, and online payments go straight into your own Razorpay account.
Your Solar Company
Your 5 kW solar installation is scheduled for tomorrow, 9:30am. Our team will call before arriving.

Why not just wing it
9pm on a Tuesday. A customer asks where their installation stands.
Spreadsheets + WhatsApp
You call the site supervisor and wait for him to check.
- No signal, no update until he is back in range
- BOQ retyped by hand for every project
A generic CRM
You open a dashboard built for selling software, not solar.
- No idea what PM Surya Ghar even is
- A quote is still a template, not a real BOQ
SORA
You already knew. It flagged itself this morning.
- Logged from the roof, signal or not
- An accepted quote opens the project by itself
Home ground
Made for Indian solar
PM Surya Ghar subsidy, DISCOM consumer numbers, net metering, GST invoices, PF, ESI and professional tax, and rupee amounts in lakhs and crores — because a system that gets these wrong costs more time than it saves.
PM Surya Ghar
Subsidy calculated correctly, never guessed for a commercial or government account.
GST-ready
Invoices and BOQs carry HSN codes and tax breakups an accountant expects.
Payroll compliance
PF, ESI and professional tax follow Indian statutory rules by default.
₹ in lakhs & crores
Every amount reads the way it is spoken, not translated from a Western format.
Every morning
From business software to a business that tells you things
SORA already knows every project, every rupee and every date in it. So it checks them every morning and tells you what needs you — before you go looking.
Every line comes from your own records — what is overdue, what is unassigned, what is about to slip. Never a guess, and never invented.

Going live
We don’t hand you a login and disappear
Most business software fails because nobody sets it up properly and the team quietly goes back to WhatsApp. Choose setup at signup — a one-time fee, optional — and somebody from our side does these six things with you. Prefer to do it yourself? The guided setup inside SORA walks you through the same steps.
- 01Understand how you workYour stages, your approvals, your rates — before anything is configured.
- 02Set SORA up around thatNot a blank workspace with a manual. Configured for your company.
- 03Bring your data acrossRunning projects, customers, catalogue and prices from your spreadsheets.
- 04Train your teamSeparately for the office and the field, because they use different halves.
- 05Go live on real workStarting with new jobs, so nothing in flight is put at risk.
- 06Stay with you afterAdoption is the hard part and it happens in the first month, not on day one.
This is what the one-time setup fee pays for. It is optional, and it is the difference between software you bought and software you use.
Proof
What running on SORA actually changes
SORA is early. We would rather tell you that plainly than invent a logo wall. Here is what we track for every company that runs on it, and what will appear here as it becomes true.
—
Quotation turnaround
first enquiry to a sent quotation
—
Survey to quotation
time from site visit to price in hand
—
Coordination hours saved
calls, WhatsApp checks and follow-ups removed
Measured, not marketed — figures publish here once a company has run a full quarter on SORA.
Unlimited users
Compare the total, not the per-user price.
A tool that charges per user looks cheap for the first login. Then you add the surveyor, the crew leads, the store, accounts — and the bill is a different number. SORA doesn’t count people.
Multiply any per-user price by 25 and then ask what a seat costs when the next person joins. With SORA the answer is nothing — and the projects, leads, quotations and customers are unlimited too.

Before you ask
Questions worth answering upfront
Anything else, write to support@tantratechnologies.com.
Is there a limit on users, projects or leads?
No. Every person in your company gets a login, and projects, leads, quotations and customers are all unlimited. There is no per-user fee, so your bill does not change when you hire.
Is my data safe if I stop paying?
Every account — including a lapsed one — can export every report as PDF, Excel or CSV. Nothing is held hostage.
Does the field app need internet?
No. Surveys, checklists and photos queue on the phone and sync the moment it finds a signal again — nothing is lost to a dead zone on a rooftop.
How long does setup actually take?
Answer six questions about how you work today and SORA sets itself up around your answers. Most teams are quoting from it within a day — and if you would rather we did the setup, that is a one-time option at signup.
Can I bring in projects I already have running?
Yes — existing projects import with their stage and cost history intact, so nothing has to restart from zero on day one.
What happens to GST, PF and ESI?
Built in, not bolted on — invoices, payroll and statutory deductions follow Indian rules by default, not a US-shaped template.
One plan. One price. Zero guesswork.
See exactly what SORA will do for your business, and what it costs — before you commit to anything.
