Why a custom CRM instead of an off-the-shelf one?

The software fits your process, not the other way round. You pay no per-seat licence and, depending on the agreement, you own the source code, so the CRM becomes a lasting asset rather than a subscription.

When is the first working version ready?

Typically within one week, on a staging environment you can access. New modules are then added in weekly sprints and you see a working build at the end of each one.

How many users can it handle?

Go-based services and a horizontally scalable architecture are designed for thousands of concurrent users and high-volume lead traffic.

Will it integrate with our existing systems?

Yes. The WhatsApp Business API, Meta, Google and TikTok lead forms, ERP and accounting software are connected through REST APIs or webhooks; systems without an API are integrated with browser automation.

Custom CRM Software Development

We bring your sales, quotations, customer tracking, and team task workflows together in a single panel. By building a modular and scalable CRM infrastructure tailored to your business model, we reduce manual workload and increase reporting and decision-making speed.

A custom CRM is software that brings sales, quotes, customer follow-up and team tasks into one panel, built around your workflow instead of forcing your process into an off-the-shelf package. Moserra develops modular, scalable CRM systems in Go and PHP and connects them to ad platforms, the WhatsApp Business API and your ERP.

Who is it for?

Sales teams that receive leads from several channels (Meta ads, web forms, WhatsApp, phone) and track them in spreadsheets
Companies that cannot model their workflow in packaged CRMs or are tired of per-seat licence costs
Organisations that need different permissions per branch, region or team

What problems does it solve?

Leads answered too late, or the same lead called by two agents
No visibility into where the sales funnel loses customers
Reports prepared by hand every week
Customer history scattered across email, WhatsApp and spreadsheets

What we build

Lead capture and automatic distribution: pool system, fair assignment, hot/cold/converted status tracking
Sales funnel, quotes and tasks: every stage has an owner and a visible duration
Role- and branch-based permissions: each team sees only its own data, management sees everything combined
Real-time dashboard and reports: by campaign, agent and conversion, exportable
Integrations: WhatsApp Business API, Meta Ads, Google Ads, TikTok, ERP and accounting systems

Process and timeline

Discovery and analysis, screen prototypes, weekly development sprints, testing and launch. A first working version is typically live on a client-accessible staging environment within one week, then extended sprint by sprint.

How is pricing determined?

Pricing depends on the number of modules, the complexity of integrations, the architecture (monolith or microservices) and the ownership model (standard licence or full source-code transfer). There are no per-seat monthly fees.

An example from production

ErdSağlık | Multi-Region Health Call Center and Patient Operations CRM

ErdSağlık is an end-to-end operational CRM that manages the entire patient journey of a multi-regional health call center from a single screen. Going beyond a simple registration log, it establishes a seamless flow where incoming calls turn into relevant contacts, then into appointments, and finally into treatment and follow-up processes. The management panel displays the real-time status based on region, agent, and campaign, while authorization management ensures that each team can only see their own data. Thanks to its flexible structure, new regions, specialties, or call types can be added in a short time.
