New Bondhu — the AI layer — is live across every product

AI automation for the businesses everyone else skipped.

Four million small businesses in Bangladesh run on a paper khata and a phone with patchy data. We build the tools that actually work there — offline, in Bangla, priced in taka, with AI doing the boring parts.

The platform every Jaantrix product and custom build stands on

  • Offline-first sync
  • bKash & Nagad

Our mark

The arrow inside the J is deliberate — every product we build is meant to lift a business up, not just digitise what it already does.

How much are COD returns actually costing your business?

Calculate now →
The problem we started from

A shopkeeper doesn't need an ERP. She needs to know if today was a good day.

Observation 01

The ledger is paper

Sales, credit, expenses — all in one ruled notebook under the counter. When it's lost or soaked, so is the business's entire history.

Observation 02

The network drops

Cloud software fails at the worst moment: mid-sale, mid-rush. Most tools built for Dhaka assume Dhaka-grade internet.

Observation 03

The software is in English

"Accounts Receivable" means nothing at a counter where the word is বাকি. Language is not a translation layer. It's the product.

In the box

What each one actually ships with.

Every business has a money problem and a customer problem. We built one product for each — and the platform underneath them is how we ship custom SaaS for everyone else. Flip any card for its spec sheet.

Money

HisabKitab

Bookkeeping that works with no signal. Income, expenses, credit (বাকি), stock, invoices and staff roles — in Bangla and English, on a phone, offline. Entries queue locally and sync themselves the moment the network returns.

HisabKitab · spec sheet

  • Business & personal modes
  • Offline-first durable sync queue
  • Multi-item invoices & stock
  • Bank / NBR-ready statements
  • Six staff roles, invite by phone
  • Bangla + English throughout, including print
Customers

WACRM

A CRM that lives inside WhatsApp, because that's where Bangladeshi customers already are. Shared team inbox on the official Business API, sales pipelines, broadcast campaigns, and no-code automations — self-hostable, so your customer data stays yours.

WACRM · spec sheet

  • Shared inbox, many agents, one number
  • Kanban sales pipeline
  • Template broadcasts & delivery tracking
  • Visual automation builder
  • AI-drafted replies from your own policies
  • Self-host or we host it
Custom

Custom SaaS

When your problem doesn't fit an off-the-shelf product, we build the product. Discover, build, launch, run — on the same offline-first, Bangla-first, AI-assisted platform our own apps stand on, so you get months of foundation on day one.

Custom SaaS · what we build

  • Order & delivery management
  • WhatsApp chatbots & AI agents
  • Booking, billing & membership systems
  • Internal dashboards & automations
  • Fixed-price written scope before any build
Why business owners come to us

Not more software to learn. Fewer things you have to do yourself.

Every product and every custom build starts from the same question: what is this person doing by hand tonight that a machine could do instead?

Automated

The midnight arithmetic

HisabKitab totals the day the moment the last sale is entered — no calculator, no waiting for an accountant on Thursday.

Automated

The message you'd have sent anyway

A WhatsApp order confirmation or payment reminder goes out the second it's needed, whether you're awake, asleep, or serving the counter.

Automated

The problem nobody else will touch

If it's genuinely unique to your business, we build it once — on a platform that already solved the hard, boring parts.

Meet Bondhu

The বন্ধু — friend — behind the automation.

Bondhu is the AI layer running quietly inside every Jaantrix product — drafting a WhatsApp reply while you're serving a customer, flagging an unusual expense in HisabKitab, catching an order that needs a human before it ships. Not a chatbot you talk to. A colleague who does the part you'd rather not.

Placeholder quotes — swap for real ones before launch.

"I used to close the shop not knowing if I'd made money that day. Now HisabKitab tells me before I lock up — even the nights the internet is down."

Nasrin Begum Fashion Corner, Mirpur

"Our return rate dropped once WACRM started confirming orders before we packed them. Customers reply in two minutes instead of us calling all evening."

Tanvir Ahmed ClickBazar, f-commerce

No pitch, no obligation — a free look at where the time in your day is actually going. If HisabKitab or WACRM already solves it, we'll say so.

Vision & Mission

We were built to solve a problem, not to fill a category.

Origin

Jaantrix started with a notebook. Not ours — a stationery shop owner's, in a market where the power cuts twice a day and the mobile data is honest about being unreliable.

She knew her business better than any dashboard could. But she couldn't answer three questions without an hour of arithmetic: how much am I owed, how much did I actually make last month, and can I prove either of those to a bank.

Every piece of software offered to her was built for a different country. Cloud-only, English-only, priced in dollars, and designed around an accountant she doesn't employ. So we started building for her instead.

Our vision

AI automation in the hands of every user in Bangladesh — the shopkeeper, the seller, the clinic, the school — not just the companies that can afford consultants.

Our mission

Build offline-first, Bangla-first, AI-assisted SaaS a business owner can set up alone in ten minutes — and custom apps for the businesses whose problems don't fit a product.

How we decide things

Five rules we don't break.

Rule 01

Offline is not a feature

If it doesn't work with the network off, it isn't finished. Every write goes to the device first and syncs later — never the other way around.

Rule 02

Bangla is not a translation

We design in Bangla and English at the same time. Screens are laid out for the longer of the two, and numbers, dates and currency read naturally in both.

Rule 03

Your data is yours

Export everything, any time, in a format you can open. Our CRM can be self-hosted on your own server. We don't sell, mine, or train on your customers.

Rule 04

Price in taka, for taka earners

A tool that costs more than the problem is not a solution. Free tier that is genuinely usable, paid tiers priced against a day's margin — not a Silicon Valley seat.

Rule 05

Ship small, in public

We'd rather put a rough thing in front of ten real shopkeepers than a polished thing in front of an investor. Roadmaps get rewritten by whoever is actually using the product.

The model

Jaantrix is the studio. The products carry their own names. HisabKitab and WACRM are marketed on their own merits, to their own audiences, with the studio as the guarantee behind them — the way a publisher stands behind its books.

That's deliberate. A shopkeeper searching for দোকানের হিসাব রাখার অ্যাপ is not looking for a software company. She's looking for a khata. We meet her there, and the company name is what she finds when she wants to know who she's trusting.

The studio's job is the boring, expensive part every product needs and none of them should rebuild: authentication, billing in taka, sync, offline storage, Bangla typography, SMS delivery, and support in the customer's own language. Each new product ships faster than the last because that layer is already paid for.

Products

Built, being built, and next.

We ship narrow products that do one job completely, rather than one suite that does ten jobs badly.

How it works

From paper khata to printed accounts, in four steps.

01 / 04

Set up your shop

Name the business, pick Bangla or English, choose business or personal mode. Ten minutes, and you never touch a settings screen again.

02 / 04

Record as you go

A sale, an expense, a বাকি entry — each in under five seconds. With signal or without, the entry is saved to the phone before anything else happens.

03 / 04

See the truth daily

Today's takings, this month's profit, and exactly who owes you what — read at a glance, instead of calculated at midnight with a calculator.

04 / 04

Print for the bank

Trading, profit & loss and balance statements in correct printed Bangla, laid out the way a bank officer or the NBR expects to read them.

Problem

"How much am I owed?"

Credit is scattered across pages and memory. HisabKitab keeps one running বাকি ledger per customer, with a total you can read at a glance.

Problem

"Did I make money this month?"

Income minus expenses is not the answer when stock, rent and repayment all move. Monthly views separate them properly.

Problem

"The bank wants statements."

Print a clean trading, profit & loss and balance statement — laid out for a bank officer or the NBR, not for a screen.

Everything in the app

One app for the whole counter.

01 · Daily

Income & expenses

Log a sale or a cost in under five seconds with categories that match how a shop actually spends.

02 · Credit

বাকির ledger

Who owes you, who you owe, since when. Settle partially, and the balance updates everywhere.

03 · Stock

Products & inventory

A catalogue with purchase price, sale price and stock on hand — so margin is calculated, not guessed.

04 · Billing

Multi-item invoices

Build an invoice from your catalogue and send it. Stock moves and the sale posts to the books automatically.

05 · Growth

Investments

Track money you've put into the business, and money the business has put elsewhere, separately from profit.

06 · Team

Staff & roles

Six levels — owner, co-owner, manager, supervisor, staff, viewer. Invite by phone number; access is claimed on first login.

07 · Reports

Insights

Where the money went this month, which products carry the margin, and how this month compares to last.

08 · Personal

Personal mode

Switch a profile to personal finance and invoices, stock and staff disappear. Same app, right tool.

09 · Language

Bangla & English

Full বাংলা throughout — including printed reports, where Bangla conjuncts usually break.

The difference

Turn the internet off. Keep working.

Most "cloud" bookkeeping apps show a spinner the moment your signal drops — usually during the evening rush, when you're recording the most.

HisabKitab writes every entry to your phone first. Nothing waits on a server. When the connection returns, the queue drains in the background and your other devices catch up. You'll see a small marker while entries are pending, and that's the entire experience of being offline.

  • Entries save instantly with no network at all
  • A pending-sync count you can actually see
  • Multiple devices reconcile without duplicating
  • Install to your home screen — no Play Store needed

Questions

Before you download.

Does it really work without internet?
Yes. Every entry is written to your phone's local storage first and is readable immediately, with or without a connection. Syncing to the cloud happens in the background whenever a network is available. You can record an entire day's business in airplane mode.
অ্যাপটি কি সম্পূর্ণ বাংলায় ব্যবহার করা যাবে?
হ্যাঁ। পুরো অ্যাপ — মেনু, রিপোর্ট, এমনকি প্রিন্ট করা হিসাবের কাগজ — বাংলা ও ইংরেজি দুই ভাষাতেই ব্যবহার করা যায়। যেকোনো সময় ভাষা বদলানো যায়।
Can my staff use it without seeing everything?
Yes. There are six role levels — owner, co-owner, manager, supervisor, staff and viewer. A staff member can record sales without seeing total profit or the customer credit book. You invite people by phone number and the invitation is claimed automatically when they log in.
Can I use it for personal money instead of a business?
Yes. Set the profile to personal mode and the business-only sections — invoices, product management, staff — disappear. You keep income, expenses, debts and investments. You can run a business profile and a personal profile from the same account.
Will a bank accept the reports?
HisabKitab prints a conventional trading account, profit & loss account and balance statement laid out for paper, not for a screen. Bangla renders correctly in print, which most PDF tools get wrong. Whether a specific bank accepts self-prepared accounts is their policy, but the format is the one they expect.
What happens to my data if I stop paying?
Your account drops to the free tier. Nothing is deleted, and you can export everything at any time in a format you can open in a spreadsheet.

Where the money goes

A return costs you before it's even back on the shelf.

Cost 01

The reverse trip

Most couriers charge to bring a rejected parcel back — often close to what forward delivery cost, for zero revenue.

Cost 02

Packaging you don't get back

Box, poly bag, tape, inserts — bought and used whether or not the customer keeps the order.

Cost 03

Stock that can't go out again

Handled, opened, sometimes damaged in transit twice. A share of every return isn't resellable as new.

The fix most sellers skip

Confirm the order before the courier ever leaves.

Most COD returns aren't a change of heart — they're an order nobody meant to place, an address that was never right, or a customer nobody reached before dispatch. A confirmation message before the parcel ships catches most of that for the cost of one WhatsApp template.

  • Auto-sent the moment an order comes in, before packing starts
  • Customer confirms, edits the address, or cancels — in one tap
  • Unconfirmed orders flagged for a human call instead of a blind dispatch
  • Runs on the same WhatsApp number you already sell from

Custom SaaS · Services

Discover. Build. Launch. Run.

When your business doesn't fit an off-the-shelf product, we build the product — on the same platform HisabKitab and WACRM already run on. You get months of foundation on day one, and a team that stays after launch.

How an engagement works

Four steps, no mystery.

01 · Discover

We learn the counter

A week inside your actual workflow — who records what, where it breaks, what a good day looks like. You get a written scope with a fixed price before anything is built.

02 · Build

Weekly working software

Not slideware — a link you can open every week, in Bangla and English, that your own staff try on their own phones.

03 · Launch

We stand at the counter

Data migrated from paper or spreadsheets, staff trained in Bangla, and the first live week supported day by day.

04 · Run

We keep it running

Hosting, monitoring, backups and small changes on a monthly retainer — or hand it fully to your own team with documentation.

What we're good at

Expertise, named plainly.

We tell you exactly what we build with, because vagueness is how software projects go wrong.

AI & automation

AI agents & chatbots

WhatsApp and web chatbots that answer from your own FAQs and policies, draft replies for your team, and hand cleanly back to a human.

Messaging

WhatsApp Business API

Official API setup, template approval, broadcast campaigns and shared team inboxes — the plumbing WACRM is made of.

Web & mobile

Next.js & PWA

Installable web apps that work offline on mid-range Android — no Play Store gatekeeping, one codebase.

ইন্টারনেট ছাড়া দোকানের হিসাব রাখার অ্যাপ: কোনটা আসলে কাজ করে

Almost every bookkeeping app sold in Bangladesh claims to work offline. Most of them mean something much narrower than what a shopkeeper needs at 8pm during a rush with two bars of signal.

There are three different things a company can mean by "offline", and only one of them is useful behind a counter.

The three kinds of "offline"

1. Read-only cache

The app remembers screens you have already opened. You can look at yesterday's total, but the moment you try to save a new sale, it fails or spins. This is the most common version, and it is nearly worthless during the hours you're busiest.

2. Optimistic UI without durability

The entry appears on screen instantly and is held in memory. It looks like it worked. If the app is closed or the phone restarts before the network returns, the entry is gone — and you won't be told. This is worse than the first kind, because it is silently wrong.

3. Local-first with a durable queue

The entry is written to storage on the device before anything else happens, and stays there until the server confirms it. Close the app, restart the phone, leave it a week — the record survives and syncs when it can.

The test isn't whether the app opens offline. It's whether a sale you recorded offline is still there after you restart the phone.

How to test an app in four minutes

  • Turn on airplane mode.
  • Record three entries — a sale, an expense, and a credit entry against a customer.
  • Force-close the app completely, then restart the phone.
  • Open the app, still in airplane mode. All three entries should be there, with some visible indication that they haven't synced yet.
  • Turn the network back on and watch the pending count go to zero.

If entries vanish at step four, the app is doing optimistic UI without durability. If you can't create them at step two, it's a read-only cache. Either way, you now know before you've trusted it with a year of your business.

Why this is hard to build

Doing it properly means the phone has to be treated as the source of truth, not the server. That forces you to solve conflicts — the same customer's balance edited on two devices, or an invoice created offline against stock that has since sold out. Most teams skip it because the demo looks the same either way, and only the customer discovers the difference.

We built HisabKitab local-first from the first commit for exactly this reason. Entries queue on the device and drain in the background, and the app tells you how many are still waiting rather than pretending everything is fine.

Try it

Run the four-minute test on HisabKitab.

Free to start, and it works in airplane mode from the first entry.
