The basics

What is custom CRM software?

CRM (customer relationship management) software keeps every lead, customer, conversation and deal in one place so your team knows who to follow up with and when. A custom CRM is built around your own sales stages, fields and reports, instead of a generic tool you have to bend.

It makes sense when your process doesn't fit off-the-shelf CRMs, when per-user fees keep rising, or when you need the CRM tightly connected to your ERP, website or WhatsApp.

FAQs

Custom CRM development: common questions

How much does custom CRM development cost?

Integrations with WhatsApp, ERP or a mobile app add to the cost. We give a fixed quote after a free call.

Custom CRM or Zoho / HubSpot / Salesforce?

Ready-made CRMs are quick to start and suit standard sales processes. A custom CRM is better when your process is unique, you need deep integrations, or per-user fees are adding up.

Can leads from our website and ads go straight into the CRM?

Yes. Website forms, Google Ads and Meta lead forms can create leads automatically and alert the right person.
