Short answer
What does a SIM based CRM cost and do for a small business?
RMDialer is a SIM based CRM for small businesses that runs on the phones the owner and staff already use. The dialer, caller ID, call log and call analytics are free forever with no account. A plan adds the customer record after every call, reminders that ring like an alarm and can carry a WhatsApp message, automatic WhatsApp after calls, and paid clients with renewal and payment-due filters. On the yearly plan it costs ₹1,908 per user per year plus taxes: ₹1,908 for the proprietor alone, ₹5,724 for a shop of three and ₹9,540 for five. Calls go on your own SIM plan, so there are no per-minute charges. Records live on the account, so a lost phone loses nothing. Keep the khata or accounts software for credit and bills.
Key takeaways
The dialer and call analytics are free forever.
A shop of three pays ₹5,724 a year plus taxes.
Reminders ring and can carry a WhatsApp message.
Paid clients show who is due for renewal or payment.
Credit and bills stay in your khata or accounts software.
As the shop grows
How much does a SIM based CRM cost at one, three and five users?
Priced per user on the yearly plan, plus taxes. What changes as you add people is not the price per head but what the tool does for the owner.
Just the proprietor
₹1,908 a year
One phone, every customer call remembered, reminders that ring for the repeat orders you would otherwise forget. The free phone dialer and call analytics cost nothing even before you pay.
Proprietor plus two
₹5,724 a year
The son at the counter and a helper on deliveries each have the app. A customer who rang the shop phone yesterday is known on every phone today, and nobody promises the same order twice.
A team of five
₹9,540 a year
Now leads get assigned, the owner checks who called whom from the Web CRM, and paid customers with renewals show up in their own list before they lapse.
Prices are per user, exclusive of taxes. Teams of ten or more pay less per user, shown on the
pricing page. Before any of that, the phone dialer is free forever, and
a guide to CRM for a one-person
business covers whether you need a record at all when you work alone.

“I am a one-person business. RMDialer is the business dialer app on my own phone: every customer call becomes a record, the wedding date is the reminder, and the new collection goes out as a WhatsApp broadcast to my 600 customers from the call log. Paid clients tab shows who has paid and who has balance due.”
PRPooja RathoreOwner · Boutique and bridal wearJodhpur
“Subscription business: every client's plan expiry is a renewal reminder and every prospect from the webinar list is auto dialled the next morning. Paid vs due on each client is visible, so collections are not in my head anymore. The daily call report keeps my two callers honest.”
“Renewal reminder is the reason I pay for it. Every policy due date rings me 30 days, 7 days and 1 day before, with the client's number right there. Earlier 3 to 4 renewals a year quietly went to other agents. Small app, big difference for a single agent like me.”
“GST and ITR deadlines mean 200 client calls in a fortnight. The auto dialer runs the list, the remark goes on the client's number, and the ones who said "documents by Friday" ring the assistant on Friday. A follow up reminder app that lives inside the phone dialer is the only kind my staff will keep using.”
“Free telecalling app search brought me to the 3-day trial. Whole app, nothing locked. By day two I had imported last year's 1,200 travellers and the auto dialer was calling them for this season's packages. Paid the yearly plan on day three. The WhatsApp itinerary goes out after each call by itself.”
LDLakshmi DeviProprietor · Travel and pilgrimage toursTirupati
“Renewal reminders and call tracking for 5 agents on Safaricom lines. Every policy renewal rings the right agent before it lapses, and I see the calls each agent made without asking. During a data outage upcountry the calls still went through on the SIM, and the notes reached the account when the network came back. Priced for a small business, which most CRMs are not.”

What owners actually use
How does a SIM based CRM compare with a khata, WhatsApp or a big CRM?
Most small businesses already run on one of the first two, and some have tried the third. Here is how each holds up on the things a shop owner cares about.

A worked example
What does a SIM based CRM change for a spare parts shop?
An auto spare parts shop in Rajkot: the proprietor, his son and one helper at the cash counter, selling mostly to mechanics.
Most of the shop's sales go to about sixty garages, and nearly all of them start with a phone call: a
mechanic with a bike on the stand needs a clutch plate by four o'clock. The business grew by word of mouth,
and the proprietor carried every repeat customer in his head, along with who paid cash and who ran a tab in
the khata. When he was away at a wedding for three days, the shop felt it.
He started alone on the free dialer, then took a plan when he noticed how often a garage rang saying "I
called yesterday, nobody called back." The app now runs on two phones, his and his son's. Each call lands on
the mechanic's card; a remark notes the part and the bike model; a monthly reminder rings for the garages
that buy engine oil in bulk. The son, who used to hand every call to his father, now sees the last order on
screen before he answers.
The khata stayed exactly where it was, and the accountant still gets it every quarter. What changed is that
a repeat customer is no longer something only the proprietor can recognise. The next time he travelled, the
counter kept running, the reminders kept ringing, and not one garage had to explain itself twice.
Fair warning
When is a SIM based CRM too much, or too little, for a small business?
It fits the phone-first shop. A few businesses are better served elsewhere.
You rarely take or make calls and sell mostly through a website checkout. An e-commerce platform's customer list will serve you better.
You need billing, GST invoices and stock in the same tool. Keep your accounting software for that; this is the customer side only.
You get a handful of calls a week from the same few people. A saved contact and a calendar alarm may be all you need, and the free dialer covers the rest.
Small business SIM CRM, CRM with SIM calling: the same shop tool
Whether you search for a small business SIM CRM or a CRM with SIM calling for a small business, you are
after the same thing: a customer record that works from the phone in a shop owner's hand, uses the numbers
customers already know, and costs what a small business can carry. The words change; the counter, the
phone and the repeat customer do not.
You will also see it called sim based crm for small businesses, small business sim crm, sim calling crm for small business and crm with sim calling for small business. They describe the same thing, so whichever phrase
brought you here, this is the page for it.
How it works
How does a small shop keep repeat customers coming back?
1
Set a reminder in two taps
Pick 5 minutes to tomorrow, or a date. Attach a WhatsApp message, and repeat it daily, weekly, monthly or every few days.
2
Let WhatsApp go out after calls
After a missed, outgoing or incoming call, a chosen template can be sent automatically, with quiet hours respected.
3
Keep paid customers from lapsing
Paid clients filter by ending today, tomorrow, the next 7 or 30 days, expired or payment due, with Renew on each card.
Questions
SIM based CRM for small business: questions shop owners ask
What is a SIM based CRM for small business?
It is a simple customer record for a small business that fills itself from the calls on the owner's and staff's own mobile SIMs. Each call is saved against the customer, reminders ring for follow-ups, and paying customers are marked with their amounts, all on the phone, without a computer or a separate data-entry routine.
Which is the best sim based crm for small business owners in India?
RMDialer is the best sim based crm for small business owners in India who sell and follow up on the phone. The dialer is free forever, and a plan at about ₹159 per user per month on the yearly plan adds the customer record after every call, reminders that ring, automatic WhatsApp and paid-client renewals. A shop of three pays ₹5,724 a year plus taxes.
Is RMDialer a sim based crm for small business?
Yes. RMDialer is a sim based crm for small business: it replaces the phone's dialer, keeps each customer's calls, status and remarks together, rings follow-up reminders and tracks paid customers and renewals. One person can use it alone, and a small team shares one account.
Is there a free CRM for small business?
RMDialer's phone dialer, caller ID, call log, call analytics and daily free WhatsApp sends cost nothing and need no account. The customer record, reminders and team features are on a plan, with every feature free for 3 days first. Most fully free CRMs limit users, contacts or reminders, so check the limit that would hit you first.
Do small businesses really need a CRM?
A business that sells on the phone and relies on repeat customers does, even if it never calls it a CRM. The test is simple: if a customer you promised to call back last week slipped through, or only one person remembers what a buyer prefers, the business needs a record that does not live in one head.
What is the cheapest CRM for a small shop?
The cheapest is the one that does not need extra hardware or training. RMDialer is ₹1,908 per user per year plus taxes on the yearly plan, runs on phones you already own, and needs no computer for daily work. There are no per-minute charges, because calls go on your own SIM plan.
Can I use it alone before adding staff?
Yes. Start with one user on your own phone, and add your son, a counter person or a delivery helper to the same account later. Everything you recorded while working alone is there for them from their first day.
I keep credit in a khata. Does this replace it?
No, keep the khata or your accounting software for credit and bills. What this replaces is remembering: who asked for what, who promised to pay on Friday, who is due for a repeat order. A paid-client record can hold a sale amount and a due date as a reminder for the conversation.
Can I send WhatsApp messages to customers automatically?
Yes. After a missed, outgoing or incoming call, or when a lead's status changes, a chosen template can go out automatically through the WhatsApp API, with quiet hours to hold messages overnight. Meta charges per conversation on the API. Manual WhatsApp from a call is free every day with a free account.
How do reminders work for repeat customers?
Set a reminder with a quick time or a date, add a note, and optionally attach a WhatsApp message. It can repeat daily, weekly, monthly, yearly or every few days, which suits a garage buying oil every month or a customer due for a yearly service. The phone rings for it like an alarm.
What if the owner uses an iPhone and staff use Android?
That works. The iPhone app has every feature except the call log, so the owner still sees customers, reminders, remarks and paid clients, while staff on Android get calls logged automatically. Everyone shares the same records on the one account.
Can I see which customers are due for renewal or payment?
Yes. The paid clients list filters by ending today, ending tomorrow, the next 7 or 30 days, expired and payment due, and each card has a Renew button. Customers who pay yearly or monthly stop lapsing just because nobody noticed.
Is my customer data safe if my phone is lost?
Yes. Records sit on the account, not only on the handset, so a new phone logs in and carries on. Removing a staff member from the account also stops their phone reaching the shop's customer records.
Do I need a computer or internet at the shop?
Neither is required for daily work. Calls, reminders and records all run on the phone and work without data, sending to the account when a connection returns. A computer only helps when you want the Web CRM's bigger reports.
How long does it take to set up?
An afternoon. Install the app, make it the phone's dialer, log in, import your customer list from Excel if you have one, and set the handful of statuses you actually use. Most shops are working from it the same day.
