And the big question

Value is great! But is it value for money?

Crux starts at just S$1,499 one-time and an initial setup fee. The payback period spans from few months to a year depending on usage due to cost savings and increased revenue that our customers attribute to Crux. Unlike Cloud and SaaS based providers, Crux does not incur monthly per user costs. Crux helps,

  • Link up your HQ and branch offices across countries with one-time per employee cost as low as S$6.00
  • Lower telecom rental by moving from analog to digital landlines
  • Eliminate your staff mobile reimbursements for voice calls and international roaming
  • Lower international tariff (lower than IDD) by subscribing to cost-efficient international telecom operators
