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.
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
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.
Drag the ring, use the arrow keys, or tab straight to a card. Every card opens its product.
Bookkeeping that works with no signal — income, expenses, credit (বাকি) and stock, in Bangla and English, syncing itself the moment the network returns.

How much are COD returns actually costing your business?
Sales, credit, expenses — all in one ruled notebook under the counter. When it's lost or soaked, so is the business's entire history.
Cloud software fails at the worst moment: mid-sale, mid-rush. Most tools built for Dhaka assume Dhaka-grade internet.
"Accounts Receivable" means nothing at a counter where the word is বাকি. Language is not a translation layer. It's the product.
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.
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.
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.
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.
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?
HisabKitab totals the day the moment the last sale is entered — no calculator, no waiting for an accountant on Thursday.
A WhatsApp order confirmation or payment reminder goes out the second it's needed, whether you're awake, asleep, or serving the counter.
If it's genuinely unique to your business, we build it once — on a platform that already solved the hard, boring parts.
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.
See where Bondhu shows up"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."
"Our return rate dropped once WACRM started confirming orders before we packed them. Customers reply in two minutes instead of us calling all evening."
"We told Jaantrix what our booking desk actually needed. Three weeks later it existed — not a six-month agency timeline."
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.
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.
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.
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.
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.
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.
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.
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.
We ship narrow products that do one job completely, rather than one suite that does ten jobs badly.

No card. No accountant. Works on any Android phone.
Name the business, pick Bangla or English, choose business or personal mode. Ten minutes, and you never touch a settings screen again.
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.
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.
Trading, profit & loss and balance statements in correct printed Bangla, laid out the way a bank officer or the NBR expects to read them.
Credit is scattered across pages and memory. HisabKitab keeps one running বাকি ledger per customer, with a total you can read at a glance.
Income minus expenses is not the answer when stock, rent and repayment all move. Monthly views separate them properly.
Print a clean trading, profit & loss and balance statement — laid out for a bank officer or the NBR, not for a screen.

Where the money went this month, which products carry the margin, and how this month compares to last.
Switch a profile to personal finance and invoices, stock and staff disappear. Same app, right tool.
Full বাংলা throughout — including printed reports, where Bangla conjuncts usually break.
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.

Talk to us about WACRMMost couriers charge to bring a rejected parcel back — often close to what forward delivery cost, for zero revenue.
Box, poly bag, tape, inserts — bought and used whether or not the customer keeps the order.
Handled, opened, sometimes damaged in transit twice. A share of every return isn't resellable as new.
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.
Order confirmation, delivery reminders and return follow-ups — set up on your WhatsApp number in days, not months.
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.
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.
Not slideware — a link you can open every week, in Bangla and English, that your own staff try on their own phones.
Data migrated from paper or spreadsheets, staff trained in Bangla, and the first live week supported day by day.
Hosting, monitoring, backups and small changes on a monthly retainer — or hand it fully to your own team with documentation.
We tell you exactly what we build with, because vagueness is how software projects go wrong.
WhatsApp and web chatbots that answer from your own FAQs and policies, draft replies for your team, and hand cleanly back to a human.
Official API setup, template approval, broadcast campaigns and shared team inboxes — the plumbing WACRM is made of.

Practical guides on running the money side of a small business in Bangladesh — written in the language you keep your books in.
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 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.
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.
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.
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.
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.
Free to start, and it works in airplane mode from the first entry.
Open HisabKitabWhether you want to start with HisabKitab, get into the WACRM beta, or have us build something for your business — this reaches a person, not a queue.
