Why this exists

You already keep the books. They are simply in your head.

Who you owe. What the supplier promised on the phone. Which employee took an advance. What yesterday actually earned. It works perfectly well — until a bill goes missing, a supplier remembers the figure differently, or your chartered accountant asks for March.

Bookkeeping applications ask you to stop and enter data. Nobody stops to enter data at the counter with a customer waiting, so the application falls silent by the third week and the books return to where they were.

Senni asks you to change nothing. You already forward bills and send voice notes. Send them to Senni instead.

However you already work

Send it the way you would tell a person.

There is no correct format and nothing to fill in. Whatever reaches Senni gets read.

📄 A photo of the bill

Snap it and carry on

The supplier hands over a bill; you photograph it and put the phone down. Senni reads the supplier, date, amount and GST, and adds it to what you owe. Twenty at a time is fine.

🎙 Or just say it out loud

Ten seconds, hands busy

"Paid Ramesh one thousand." "Kumar took two thousand advance." "Two boxes damaged, he will adjust it." Money becomes an entry, everything else becomes a note, and you never have to decide which.

How it works

Three things. That is the whole product.

No dashboard to learn, no data entry, and no training required for your staff.

Everything you already send lands in one of two places. Ask a question and the answer is assembled from both — the balance from the ledger, the reason from the diary.

Forward it

A photograph, a PDF or a payment screenshot — from you or from your staff on their own phones. Send twenty together at month end and Senni reads all of them, then replies once.

Or simply say it

"Paid Ramesh one thousand." "Today's sale twenty-eight thousand." "Kumar promised delivery on Friday." Money becomes an entry. Everything else becomes a note. You never have to decide which.

Ask any time

Who you owe, what a supplier said in March, how much cash should be in hand tonight. Answered from your own records, with the original bill one tap away.

Two kinds of memory

The money, and everything said around it.

Most applications record only the first. The disagreements you actually get into are about the second.

The ledger

Your books, kept properly

Every rupee, calculated exactly and traceable to the bill it came from.

Bills and payments kept as separate records, so a part payment remains a part payment
A running balance for every supplier, settled against the oldest bill first
Staff salary and advances, netted against each other
Daily sales, with cash counted separately from UPI
Rent, electricity and salaries entered once, then remembered every month
Nothing is ever deleted; every correction leaves an audit trail

The diary

What would otherwise be forgotten

A voice note from the counter, kept against the person it concerns and returned to you months later.

"Two boxes damaged. Ramesh agreed to adjust it in the next bill."
"Kumar promised delivery on Friday" — and a reminder when Friday arrives
"The rate has gone up again" — attached to that supplier, beside their balance
Reminders set by voice: "remind me about rent on the 25th"
Ask months later and receive the note and the balance in one answer

What it answers

The questions you ask every day.

Each one answered from your own records — never estimated, and always with the entries behind the figure.

Who do I owe, and how much?

Every supplier you owe, largest first, with the individual bills behind each figure.

How much has he already taken?

Staff advances set against salary and netted automatically. Visible to the proprietor alone.

What did today do?

The day's sales, cash and UPI shown separately, and how much cash should be in hand.

What did that supplier say?

The note you recorded in March, returned alongside what they are owed today.

Built for how businesses actually run

Not a cut-down version of accounting software.

Your staff can send too

Add them using a join code, free and without limit. They forward bills from their own phones and see nothing else — neither balances nor salaries. Remove a person and their entries remain; only their access is withdrawn.

More than one business

Each business is given its own Senni number. Send to that number and the bill enters that set of books. Nothing to select and nothing to tag.

Your accountant, taken care of

The month's ledger as a proper spreadsheet, with GST split out and every bill image linked. Emailed as soon as the month closes, and only if you ask for it.

Six years of records

GST law requires records to be retained for 72 months. Every original — photograph, PDF or voice note — is filed under your business, dated, and never overwritten.

Made for a noisy counter

Voice notes recorded where you are standing, not dictation into a form. Senni repeats back what it understood, so any mistake is visible within seconds. English today, with further Indian languages to follow.

Never invents a figure

Every figure is calculated exactly from your own entries, not produced by a chatbot. When Senni does not have the detail, it says so instead of estimating.

Save a different Senni contact for each business. Whichever one you send to is the book it goes into — nothing to select and nothing to tag. Ask a question and you get the position across all of them at once.

Why it pays for itself

Your accountant stops chasing you.

Most of what a chartered accountant bills for at year end is reconstruction — chasing missing bills, deciphering a bag of slips, working out which payment settled which invoice. Senni hands them a month that is already in order: every bill dated and categorised, GST split out, each entry linked to the original image.

Cleaner books cost less to file, close faster, and leave far less room for a notice later.

And a second brain for you.

What a supplier promised in March. Which employee has taken how much. The rate that quietly went up twice. It is all recorded the moment you say it, and returned the moment you ask — so you can stop carrying it.

Questions

Straight answers.

Do I need to install anything?

No. Senni is a WhatsApp number that you save like any other contact. There is a web page as well, for when you wish to see everything together, but you are never required to open it.

Is this an accounting package? Will it file my GST returns?

No, and deliberately so. Senni maintains the record and hands it to your chartered accountant in the form they require. Filing, input tax credit matching and returns remain with them, which is their profession and they do it better.

Will it read handwritten bills and small slips?

Usually, yes. When it cannot, it says so and shows you the photograph rather than recording an incorrect figure. A bill that could not be read is still filed and still searchable; it is simply not counted until you confirm what it says.

What is the point of the notes and reminders?

Most of what you need later was never written on a bill. A damaged delivery, a rate that changed, a promise made on the phone. Senni keeps those against the supplier they concern, so when you ask what is owed you also get what was said.

Do I pay for every staff member?

No. Anyone who only forwards bills and voice notes is free, however many of them there are — those are the people making your books complete, and charging for them would work against you. You pay ₹99 a month only for someone who can open the books and see balances, such as a partner, a manager or your accountant.

Can my staff see what I pay everyone?

No. Salary and advance figures are visible to the proprietor alone. Staff you add can send bills and see that they were recorded, and nothing further.

What happens to my data if I leave?

It belongs to you. You may export everything, or ask us to delete it; both are available on request. We retain records for as long as you keep the account, because GST law expects six years of them.

How is this different from a khata app or a spreadsheet?

Those require you to stop and enter data, which is precisely the moment a business owner does not have. Senni takes what you are already sending — a forwarded bill, a voice note — and does the recording itself.
