The Problem

Off-the-Shelf CRMs Are Designed for the Average Business. Is Yours Average?

Salesforce, HubSpot, and Zoho are built for millions of customers simultaneously. They cannot be built around your specific pipeline, your unique sales stages, or your exact reporting needs.

The result — your team uses 30% of the features, ignores the rest, and maintains a parallel spreadsheet for everything the CRM cannot handle.

Sound familiar?
Pipeline stages that do not match how you actually sell
Monthly per-seat fees growing faster than your revenue
Reporting that shows activity metrics, not commercial outcomes
A CRM your team logs out of as soon as the manager stops watching
Three integrations that almost work — but not quite

Who It's For

Who Needs a Custom CRM?

Sales Teams With a Complex Pipeline

If your sales cycle has more than three stages, involves multiple stakeholders, or varies by product or region — generic pipeline views will always feel like a compromise. A custom CRM models exactly how your deals move.

Businesses Paying for Seats They Do Not Use

Per-seat pricing scales against you. As your team grows, so does the monthly bill — whether everyone uses the CRM or not. A one-off build eliminates the subscription entirely.

Operations Teams Running on Spreadsheets

When your CRM cannot capture the data your operations team actually needs, spreadsheets fill the gap. A custom build eliminates the parallel system and gives everyone a single source of truth.

Companies With Reporting Gaps

If your current CRM cannot produce the commercial reports your leadership team actually needs — win rate by product, pipeline velocity by rep, revenue by source — we build reporting around your metrics from day one.

Integrations

Connected to the Tools You Already Use

Your CRM does not exist in isolation. We build integrations that close the gaps between your sales, marketing, finance, and operations teams.

Email & Calendar

Two-way sync with Gmail and Outlook means every email, meeting, and call is logged automatically against the right contact and deal — no manual entry. Your team uses the tools they already know; the CRM captures the activity behind the scenes.

GmailOutlookGoogle CalendarMicrosoft 365

Accounting & Finance

Link deals directly to invoices and payments. Know which clients are live, which are overdue, and which pipelines are converting to revenue — all from within the CRM. Eliminates the switch between your sales system and your accounts platform.

XeroQuickBooksSageFreeAgent

Marketing & Automation

Close the loop between marketing and sales. When a lead responds to a campaign, fills in a form, or opens a sequence, the CRM updates automatically. Nurture sequences, lead scoring, and re-engagement workflows all built to your specification.

MailchimpKlaviyoActiveCampaignHubSpot Marketing

Operations & Ticketing

Connect your CRM to the tools your delivery team uses — project management, support desks, and operations platforms. When a deal closes, onboarding can trigger automatically. When a client raises a ticket, your account manager sees it immediately.

How We Build

Our CRM Development Process

01

Discovery & Mapping

We document your sales process, pipeline stages, team structure and integration requirements before writing a line of code. No assumptions.

02

Design & Architecture

Database design, user roles and interface wireframes planned in full. You approve the blueprint before development begins.

03

Phased Build

Delivered in sprints with working demos throughout. You use the system before it is finished and give feedback that shapes what comes next.

04

Data Migration

Your existing contacts, deals and history migrated cleanly from spreadsheets or your previous CRM. Nothing re-entered manually.

05

Training & Handover

Full team training, documentation and 30-day post-launch support included. We do not hand over and disappear.

Why NetTrackers

Why Choose NetTrackers to Build Your CRM?

We Build. We Do Not Configure.

We are software developers, not Salesforce consultants. We write code — not just drag-and-drop configurations. If your process needs a custom workflow engine, a bespoke data model, or logic that no platform supports, we can build it.

Discovery Before Development

Before writing a line of code we map your sales process in detail — pipeline stages, team structure, reporting needs, integration requirements. The blueprint is approved before development begins. No assumptions.

Fixed Price. No Surprises.

Every project is scoped and priced upfront. No hourly billing, no scope creep invoices, no retainer required unless you want ongoing development. You know the number before you sign anything.

You Own It Entirely

The codebase, the database, the data — all yours. We hand over full source code at the end of the project. No vendor lock-in, no licensing dependency, no platform risk if we change our pricing.

Post-Launch Support Included

30 days of post-launch support is included in every project. We train your team, document the system, and are available while you bed it in. Ongoing development retainers are available for clients who need regular changes.

FAQ

Common Questions About Custom CRM Development

Off-the-shelf CRMs are built for every business simultaneously, which means they include features you will never use and still cannot replicate the specific workflow your team actually follows. A custom CRM is designed around your pipeline, your terminology, your data, and your reporting needs — not a vendor's assumptions about what a sales process should look like.

Most projects take 8–16 weeks from discovery to go-live, depending on complexity. We build in phases, so your team can start using core features while the remaining modules are being developed. You are not waiting for a big-bang launch.

Every project is scoped and priced individually after a discovery call. Pricing depends on the number of pipeline stages, user roles, integrations, and reporting requirements. We provide a fixed-price proposal before any work begins — no hourly billing, no surprise invoices.

Yes. Data migration from Salesforce, HubSpot, Zoho, spreadsheets, or any legacy system is included as standard. We clean, map, and import your contacts, deal history, and notes so you are not re-entering years of data manually.

The system is yours to evolve. We build with modification in mind, and changes — new pipeline stages, additional fields, new reports, new integrations — can be added at any point. We offer ongoing development retainers for clients who want regular updates.

Yes. We integrate with Gmail, Outlook, Google Calendar, Microsoft 365, Xero, QuickBooks, and most other tools your team uses. Activity is logged against the right contacts automatically — no manual entry.

You own everything — the codebase, the database schema, and the data. There is no licensing dependency on NetTrackers after the project is complete. You can host it where you choose and have another developer continue work on it if needed.

Every project includes 30 days of post-launch support. We train your team, document the system, and are available while you settle in. After that, you can engage us on a support retainer or return for individual development work as your needs evolve.
