FluxBilling and Blesta are both billing platforms for hosting providers, but they sit at different scopes. Blesta is a PHP application known for clean, readable code and a straightforward licence, and it concentrates on billing, invoicing, client management and support; data-centre inventory is not part of it. FluxBilling adds that layer natively: DCIM with racks, U-positions and cabling, IPv4 and IPv6 IPAM, power and PDU monitoring, and bare-metal plus VPS provisioning live in the same PostgreSQL schema as invoices and clients, behind a React 18 panel on Bun and Express, one K3s pod and one isolated database per tenant. Integrations — payment gateways, hypervisors, notifications — are visual flows stored as JSON rather than PHP extensions on disk. Plans start at €4.95/mo and top out at €44.95/mo for unlimited clients, with a 14-day refund, no minimum term, and white-label available on every tier.
FluxBilling and Blesta, feature by feature.
The billing rows look similar on purpose — both products invoice, dun and take payments. The divergence starts at infrastructure and at how integrations are written.

If your team wants to read, audit and patch the billing code itself, Blesta has the better answer out of the box. Its source is provided under a licence people find easy to reason about, the codebase is well regarded for being clean, and a PHP developer can trace a payment through it in an afternoon. FluxBilling can be self-hosted, but that is a €1,495 one-time add-on rather than the default, and integration logic lives in visual flows in the database rather than in files you can diff.
Scope cuts the same way. If you sell shared hosting or resell someone else’s infrastructure, you do not have racks, cabling or IP blocks to track, and the DCIM and IPAM half of FluxBilling is surface you will never open. A focused biller is a legitimate architectural choice. The case for FluxBilling gets strong when you own hardware — when a rack unit, a device, an IP allocation and an invoice line should be the same set of joined records instead of two systems and a sync job.
FluxBilling vs Blesta, answered directly.
01.What is the difference between FluxBilling and Blesta?
Blesta is a PHP billing application with a reputation for clean, readable code and a straightforward licence; it focuses on invoicing, client management and support, and data-centre inventory is not part of it. FluxBilling covers the same billing ground and adds DCIM with racks, U-positions and cabling, IPv4 and IPv6 IPAM, power and PDU monitoring, and bare-metal plus VPS provisioning in the same PostgreSQL schema, behind a React 18 panel on Bun and Express.
02.How much does FluxBilling cost compared to Blesta?
FluxBilling is a flat monthly price per tier: Lite €4.95 (10 clients, 5 bare-metal servers), Plus €14.95 (250 clients, 50 servers), Professional €24.95 (500 clients, 100 servers), Business €44.95 (unlimited clients, 150 servers). Extra bare-metal capacity is €0.75 per server per month, white-label is €50/mo on any tier, and a self-host licence is €1,495 one-time. Blesta publishes owned and monthly licence options on its own site — compare against the current figures there.
03.Does Blesta include DCIM or IPAM?
Blesta is a billing-focused product and does not ship native data-centre infrastructure management. Providers who need rack, cabling, IP and power records usually run a second system alongside it and keep the two in sync. In FluxBilling those records are tables in the same database as clients, services and invoices, so a rack unit, the device in it, the IP allocated to it and the invoice it appears on are joined rows rather than synced copies.
04.Is there a Blesta importer in FluxBilling?
The packaged importer that ships in core is the WHMCS Importer, with dry-run, idempotent and resumable behaviour. There is no equivalent one-click Blesta importer today. Moving from Blesta is scoped with the team from an export of your clients, services and invoices — open a ticket with your record counts and you will get a realistic plan rather than a promise.
05.Can I self-host FluxBilling the way I self-host Blesta?
Yes, as a paid add-on. Self-hosting is a €1,495 one-time charge on top of a plan. The default deployment is hosted: each tenant runs as its own K3s pod with an isolated PostgreSQL database, and settings and credentials are encrypted with AES-256-GCM.
06.Can I try FluxBilling before committing to a plan?
There is no trial licence and no scheduled demo call. Every plan has a 14-day refund window and can be cancelled at any time, so evaluation happens in a real instance with your own data. FluxBilling is currently in open beta.
