Custom CRM & business software

Custom CRM Development That Fits the Way Your Team Actually Sells

Custom CRM development makes sense when off-the-shelf tools force your team to work around them. As a custom CRM software development company, we build CRMs and internal business software shaped around your real pipeline stages, approval rules and reports, so salespeople log activity once and managers see the numbers they actually use, without paying per-seat fees for features nobody opens.

Most of our CRM projects start with a business that has outgrown spreadsheets and WhatsApp groups. Leads arrive from the website, calls, IndiaMART or referrals, get copied into a sheet, and then quietly go cold. We replace that with one system that captures every enquiry, assigns it, reminds the owner and records what happened next.

Our custom business software development follows the same approach for adjacent internal tools: field-sales apps with check-ins, stock and order tracking, service tickets and management dashboards. We connect them to the software you already rely on, such as Tally, Zoho Books, your payment gateway or email, so data moves between systems instead of being re-typed.

Who it's for

Who Custom CRM is for

Businesses running sales on spreadsheets

Teams of 5 to 100 people whose leads, follow-ups and quotations live in Excel or Google Sheets and who keep losing track of who promised what to which customer.

Companies that outgrew Salesforce or HubSpot pricing

Organisations paying rising per-user fees for a generic CRM, while still needing custom fields, workarounds and paid add-ons to match how they really sell.

Distributors and manufacturers with field teams

Businesses with sales reps visiting dealers, retailers or sites who need GPS check-ins, order capture on a phone, beat plans and daily visit reports.

Service firms with multi-step workflows

Agencies, consultancies, education providers and installers whose work moves through approvals, documents and handovers that a standard CRM cannot model cleanly.

What you get

Features we build

Lead capture from every channel

Website forms, landing pages, WhatsApp, email, IndiaMART or JustDial enquiries and manual entries all land in one list, get de-duplicated, and are assigned to a salesperson by rules you define, such as region or product line.

Pipeline that matches your stages

A drag-and-drop board with your own deal stages, required fields per stage, expected values and close dates. Managers see stuck deals and conversion between stages rather than a generic funnel that means nothing to the team.

Follow-up reminders and task queues

Each lead carries a next action and due date. Reps get a daily list and optional WhatsApp or email nudges, and overdue follow-ups escalate to a manager, so enquiries stop silently going cold.

Quotations, orders and invoices

Generate branded quotations from a price list, convert accepted quotes to orders, and push invoices or sales entries into Tally or Zoho Books. Payment links through Razorpay, Stripe or similar gateways can be attached where needed.

Field-sales mobile app

An Android and iOS app for reps with visit check-in and check-out, photo capture, order booking, beat or route plans and offline mode for poor-coverage areas, syncing back to the main system later.

Inventory and stock visibility

Where sales depends on stock, we add item masters, warehouse-level quantities, reservations against orders and low-stock alerts, so reps stop promising goods that are not actually available.

Role-based access and audit trail

Separate permissions for reps, team leads, accounts and owners. Every change to a lead, price or order is logged with who made it and when, which helps with disputes and with handing accounts between staff.

Dashboards and exports

Live dashboards for pipeline value, rep activity, source-wise conversion and collections, plus scheduled email reports and one-click Excel exports for anyone who still wants to work in a spreadsheet.

How we work

From first call to launch

  1. 01

    Process mapping

    We sit with the people who sell, approve and invoice, look at your current sheets and forms, and document how work really flows today, including the exceptions nobody writes down.

  2. 02

    Scope and fixed quote

    We turn that map into a written feature list, screen sketches and a list of integrations, then give a fixed price and timeline for the first release, with optional later phases priced separately.

  3. 03

    Build in short cycles

    We build in two-week cycles and share a working staging link after each one, so your team can click through real screens and correct us before the details harden.

  4. 04

    Data migration and training

    We clean and import your existing leads, customers and item lists from Excel or your old CRM, run training sessions for each role, and write short how-to guides for new joiners.

  5. 05

    Go-live and refinement

    We launch, watch usage closely for the first weeks, fix issues quickly, and adjust fields or reports once real usage shows what the team actually needs.

FAQ

Frequently asked questions

How much does custom CRM development cost?

A focused CRM for one sales team usually costs ₹90,000–1.75 lakh (about $1,350–2,700). Adding quotations, WhatsApp automation, Tally or Zoho sync and dashboards moves it to ₹1.75–4.25 lakh. Multi-department systems with mobile apps and inventory go higher. We give a fixed quote once the scope is written down, and you avoid the per-user subscription fees that generic CRMs charge every month.

Should we build a custom CRM or use Zoho, HubSpot or Salesforce?

If an off-the-shelf CRM fits your process with light configuration, use it; it will be cheaper to start. Custom software development for small business teams makes sense when you are paying for many seats, relying on workarounds, need deep integration with Tally or your own systems, or have workflows like field visits or approvals that generic tools model poorly. We will tell you honestly if a packaged tool is the better choice.

Can the CRM send and receive WhatsApp messages?

Yes. We use the official WhatsApp Business Platform through Meta or an approved provider, which allows template messages for reminders and updates, plus two-way conversations logged against each lead. Meta charges per conversation or message according to its current pricing, billed to your account. We avoid unofficial WhatsApp automation tools because they risk getting your number banned.

Can you integrate with Tally or Zoho Books?

Yes. For Tally we typically use its XML or ODBC interfaces to push invoices, customers and receipts, sometimes via a small connector running on the machine where Tally is installed. Zoho Books has a documented REST API we connect to directly. We agree upfront which records flow in which direction, so accounts and sales do not overwrite each other.

Are you a CRM development company in India? Can you work with us remotely?

Yes. We are a small in-house team in Tiruppur, Tamil Nadu, and our CRM development services are delivered remotely to businesses across India and overseas. Scoping calls, demos of each build cycle and training all happen over video, and you can test every stage on a staging link before it goes live.

Who owns the source code and data?

You do. On final payment, the full source code, database and documentation are handed over, and the system runs on hosting accounts registered in your name. You are free to maintain it yourself, hire another team, or keep working with us. We do not charge licence fees for software we built for you.

Can you move our existing data from Excel or another CRM?

Yes, data migration is part of every CRM project. We map your existing columns to the new structure, clean duplicates and inconsistent entries, run a trial import for you to check, and then do a final import just before go-live. Exports from most CRMs, such as CSV files from Zoho or HubSpot, can be migrated the same way.

Where is the CRM hosted and is our data secure?

We usually deploy on AWS, DigitalOcean or another cloud provider in the region you prefer, including India, the EU or the US. Access is protected by role-based permissions, encrypted connections and regular backups. We design with India's DPDP Act 2023 and, for European or UK customer data, GDPR requirements in mind, such as access controls and deletion on request.

What happens after launch? Do you offer maintenance?

Every project includes a post-launch support period for bug fixes and small adjustments. After that, you can choose a monthly maintenance plan covering updates, backups, monitoring and a set number of change hours, or simply pay for changes as needed. Many clients add new modules, such as inventory or a mobile app, in later phases.
