Custom CRM

Custom CRM for businesses, built around your process

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

Off-the-shelf CRMs are designed for an average sales team. If your work involves site inspections, recurring maintenance, multi-stage projects or technically detailed offers, you end up keeping half the information in the CRM and the rest in spreadsheets, email and notes. A custom CRM starts from your fields, your stages and your roles, and connects to the accounting software, ERP or e-shop you already use.

We have done this for our own business too. Entryc CRM is our own product, on the web and as an Android/iOS app, with contacts, communication history, offers, follow-ups, a sales pipeline and role-based access. We have also built custom CRMs for a construction company and for a fire-safety maintenance company, where the system had to cover workflows specific to their industry.

We start with a free call to map how you work today, then give you a fixed written quote. Delivery is phased, with the first working version ready in a few days, so your team uses it early and we refine it based on real use. We host and maintain the system on our own managed servers, with support in Greek and English.

What we build into a custom CRM

Every CRM starts from your needs; these are the features clients ask for most often.

Contacts and history

Customers, companies and contact people with the full history of calls, emails, meetings and notes on a single record.

Sales pipeline

Opportunities moving through your own stages, so you can see what is pending, who owns it and where it stands.

Offers

Create offers from customer and product data, send them and track their status.

Follow-ups and reminders

Tasks and reminders per user, so no call-back or contract renewal slips through.

Roles and permissions

Each user sees and edits only what their role requires, from sales reps to management.

Integrations

Connect to accounting software, ERPs, myDATA/AADE, Google Workspace, Microsoft 365, your e-shop or anything with an API.

How we work

From first call to live, in five steps

The same process whether it is a five-page website or a platform your whole company runs on. What changes is the depth of each step, not the order.

01
Discovery call
Thirty to sixty minutes on what you do, who your customers are and what the project has to achieve. We ask about the business problem first and the technology last. No charge, no commitment.
02
Proposal & fixed quote
A written document with the scope broken down line by line, the timeline, the price and what is explicitly not included. You know the full cost before you decide.
03
Design & structure
Wireframes and page structure first, then visual design. For applications, we map the data model and the workflow before writing a line of code — that is where projects are won or lost.
04
Development & review
We build in stages on a staging server you can access at any time. You review real screens as they are finished instead of waiting months for a reveal.
05
Launch & aftercare
Go-live, analytics and Search Console setup, training for your team, written documentation, and ongoing support. Most clients keep evolving their project with us for years.

Custom web applications start from €1,200 for a focused system. A mid-sized CRM with several modules and integrations typically lands between €4,000 and €15,000. After a short free call we give you a fixed written quote.

We deliver in phases. The first working version, with contacts, history and pipeline, is ready in a few days. Further features are added based on how your team actually uses it.

Yes. We import contacts, companies and history from Excel, CSV or the system you use today, after cleaning up duplicates and incomplete records with you.

We can build Android and iOS apps on the same API, so your sales reps or technicians can look up customers and log visits in the field. Our own Entryc CRM works exactly this way, on the web and on mobile.

If your process is simple, an off-the-shelf CRM or Entryc may well be enough, and we will tell you so. A custom CRM makes sense when you have specific workflows, many integrations, or when you already pay for features you never use while missing the ones you need.

We do. We host the CRM on our own managed servers with SSL, monitoring and daily backups, and offer maintenance for security updates, fixes and new features. We reply within one business day.
