When is StackBill or StackOrbit the better fit?

  • You want someone to run it for you

    OrbitManage and the 24/7 managed support listed on the StackBill site cover operations. NexCMP is software you run yourself.

  • You need consulting or a migration

    CloudStack design and build and VMware-to-CloudStack migration are listed services. NexCMP does not offer them.

  • You want a wider catalog around the portal

    Monitoring, backup and DR, DRaaS and DBaaS are listed next to the portal. NexCMP ships AI Chat and AI Agent, bare metal, Kubernetes, Private Cloud, S3 and VPN proxy modules, and its backups use CloudStack's own Backup & Recovery.

  • You value a longer track record

    NexCMP is newer, and its control plane is a single-node process pair with no high-availability mode (see the full comparison).

When is NexCMP the better fit?

  • You want a published, fixed price

    Free for the first year, with every module included. StackBill's price depends on your node count and edition and is not published.

  • Your price should not grow with your hosts

    NexCMP has no per-node, per-VM or per-customer fee and no minimum host count.

  • You want to install it yourself today

    One command on Ubuntu 22.04 or 24.04 sets up the services, nginx and a Let's Encrypt certificate; updates are one click in the admin console.

  • You resell through partners

    Unlimited reseller domains are included, each white-label with its own retail prices and wholesale wallet.

What does switching from StackBill to NexCMP involve?

NexCMP is a separate product with its own customer accounts, wallet and invoices. It connects to your Apache CloudStack through the CloudStack API and sells that capacity; it is not a plug-in for StackBill, and this site does not describe an automated import of StackBill customers or invoices.

A practical path: look at the customer portal screens, install NexCMP against a CloudStack account, and talk to sales about how to move customers across.

StackBill alternative — frequently asked questions

Is NexCMP a drop-in replacement for StackBill?
No. They are separate products. NexCMP connects to your Apache CloudStack through its API and has its own customer accounts, wallet and invoices, so moving means onboarding customers into NexCMP. Contact sales to plan it.
Which is cheaper, NexCMP or StackBill?
StackBill prices monthly by physical hypervisor node and does not publish an amount, so an honest amount-for-amount comparison is not possible. NexCMP is free and does not depend on node count.
Is StackBill still sold?
The StackBill site shows a banner saying it is now part of StackOrbit, whose pricing page lists the plans (read 2026-10-19). Confirm availability and terms with the vendor.
Does NexCMP support platforms other than CloudStack?
Yes, one other: from version 1.3.0 NexCMP also sells virtual machines from Proxmox VE. OpenStack is in development (Soon) and not available yet.
Can I try NexCMP before buying?
Yes. The service pages show the customer portal tab by tab, with sample data: open View demo on a page such as Platform, CloudStack or Bare Metal. To see a real install, write to sales and we will walk you through one.
