Custom CRM development means building software to manage contacts, sales opportunities, activities and customer service that reflects one company's workflows rather than a standard process.

Custom CRM development with Nano Concepts

Anyone who wants a CRM of their own has usually already tried off-the-shelf solutions: too many fields nobody needs, too few for what really matters, and license costs that rise with every new employee. A custom CRM, by contrast, reflects exactly your sales stages, customer types and service processes. We develop it as a web application that works in the office, at home and on the go on a smartphone – with the views that sales, inside sales and management actually need.

01

The core of every CRM is a clean data foundation: companies, contacts, sales opportunities, quotes and the complete communication history. On top of that, we build the features that make your daily work easier – such as automatic follow-up reminders, drag-and-drop pipeline views, quote templates or a duplicate check when importing contacts. Inquiries from website forms, appointment bookings and emails land automatically with the right contact instead of disappearing in individual inboxes, and every colleague sees at once who last spoke to the customer.

02

Instead of programming a CRM yourself or investing weeks in spreadsheets, you get a solution built on project experience: among other things, we have delivered a real estate CRM portal with onOffice integration and know how sales data has to flow between systems. We import your existing contact data from Excel, Outlook or a previous CRM, cleaned up. And because the system belongs to you, you decide which features come next – without waiting for a software vendor's product roadmap.

What we deliver for you

A CRM that maps your sales process instead of the other way around – with custom pipelines, fields, roles and connections to your systems.

Sales process analysis

We map your sales stages, customer types and responsibilities and derive the data model and pipeline from them.

Contacts & customer history

Companies, contacts, notes, emails, quotes and orders live in one place and are instantly findable for authorized colleagues.

Pipeline & follow-ups

Move sales opportunities with drag and drop, schedule tasks and get reminded of open follow-ups automatically.

Form, email & calendar integration

Website inquiries, appointment bookings and emails are automatically assigned to the matching contact.

Roles, permissions & reports

Each role sees only what it needs; management gets reports on pipeline, closed deals and activities.

Data migration

We import contacts from Excel, Outlook or an existing CRM, cleaned up and without duplicates.

FAQ

Frequently asked questions about Custom CRM development

We usually implement a custom CRM with contact management, pipeline, roles and integrations in the Professional package from €8,000. Very lean solutions, such as simple contact and follow-up management, are possible in the Starter package from €2,500. We quote extensive CRM systems with many integrations individually in the Enterprise package – after the free initial consultation.

We start with the core functions, contacts and pipeline, which are often usable after a few weeks when the scope is clear. Integrations, automations and reports follow in predictable stages. We set the exact schedule after the sales workshop.

If a standard CRM largely covers your workflows, customizing it is often the cheaper choice – we will tell you that openly. A custom CRM pays off when your sales team has special workflows, many add-on modules would be needed or license costs rise sharply with the size of the team.

Simple contact lists can be built yourself with spreadsheets or low-code tools. As soon as multiple users, permissions, email integration, data protection and backups come into play, a DIY build quickly becomes costly and error-prone. We also take over systems you built yourself and develop them further professionally.

Yes. We connect email and calendar, website forms, appointment booking tools and – through their interfaces – accounting or ERP systems. We clarify which integrations make sense in the sales workshop.

We implement data protection technically from the start – with a permission concept, logging, deletion periods and hosting in German or European data centers. The legal assessment of your data processing remains with you or your data protection officer. This does not replace legal advice.
