Custom CRM software

Custom CRM is customer management software built around one business's sales and care processes, rather than buying packaged software and forcing your processes to fit it.

A good fit for
  • Businesses with specific processes that packaged CRM cannot accommodate
  • Teams managing customers in Excel/Zalo that become harder to coordinate as sales grows
  • Clear permissions are needed: staff see their own customers, managers see all
Not a good fit for
  • You need it next week — custom software takes 4–8 weeks
  • Your sales process is standard and simple — packaged CRM costs less
Need inventory, purchasing, and production management too? See custom ERP — see here.

Frequently asked questions

Have you deployed a real CRM?
Yes — an operations CRM for an agricultural exporter, managing container orders, cold storage, team payroll, cashbooks, and an internal AI assistant. See Projects for details.
Who owns the code?
You own 100% of it, with documentation. No lock-in or dependence on us.
Where does it run?
On your VPS (we help you rent one, around 200,000–500,000 VND/month) or on an internal server. Installation is included.
What about changes after the warranty?
Choose a monthly operations plan or a quote per task. Documentation also lets another IT team take over.
