When sales run on spreadsheets and desk phones, leads go missing, follow-ups depend on memory, and nobody can say which campaign paid for itself. A CRM and call centre built around your sales process puts every lead, call and commission in one system.
We have built CRMs and software call centres for an insurer, a Berlitz country headquarters and Capital Smart City, a city-scale real estate development near Islamabad. Since 2019 it has run sales for buyers in four countries from the one call centre we built.
What we build
Lead management
Every lead from every channel in one place: filtered, assigned and followed up automatically.
Software call centre
Inbound routing and outbound dialling, working with your existing SIP trunks and phone numbers.
Caller context
Agents see who is calling, and their history, before they answer.
KPIs and commissions
Targets, performance and commissions calculated from the data, not from spreadsheets.
Live reporting
Dashboards built from the day’s calls and sales as they happen, with no evening reconciliation.
Customer self-service
Sign-up, payments and progress tracking for your customers, linked to the same records.
How we work
- 1
Audit
We sit with your sales and call teams, map how a lead moves today, and review your phone setup.
- 2
Design
Pipeline stages, screens and reports agreed with the people who will use them every day.
- 3
Build and connect
The CRM and call centre built and connected to your phone lines, alongside the old setup so nothing stops.
- 4
Roll out and support
Team-by-team rollout and training, then support and new reports as the operation grows.

Questions
Can we keep our existing phone numbers and lines?
Yes. AGICO’s call centre connected to its existing SIP trunks with no change of numbers, and Capital Smart City’s office phones kept working alongside the new system.
Why not use an off-the-shelf CRM?
Off-the-shelf CRMs suit standard sales processes. If yours depends on your own pipeline stages, commission rules or telephony, a custom CRM fits it exactly, has no per-seat licence fees, and belongs to you.
Can it work across countries and time zones?
Yes. Capital Smart City’s system handles inbound and outbound calls for buyers in the US, Canada, the UK and Pakistan from one 24/7 call centre.
