Common questions answered
What is Melororium?
Melororium is a modular team workspace that unifies task management, time tracking, client CRM, and financial reporting in one application. One flat monthly fee for your whole team: from $29/mo. No seat tax, no per-user billing.
How does Melororium replace Invoice Ninja pricing?
Unlike Invoice Ninja's recurring per-seat billing, Melororium charges one flat monthly fee for your whole team: Starter $29/mo (4 users), Agency $59/mo (15 users), Studio $119/mo (25 users). Add team members and your price doesn't change. No seat tax, no hidden costs.
Is Melororium a good alternative to Invoice Ninja?
Yes. Melororium is a strong Invoice Ninja alternative for digital agencies, small teams, and studios that need fast project management, built-in time tracking, and financial visibility: without paying per-seat subscription fees.
Is Invoice Ninja's invoicing-only scope leaving your project management in a separate tool?
Invoice Ninja generates excellent invoices and manages client payments: but it is an invoicing tool, not a team workspace. Agencies using Invoice Ninja still need separate project management, time tracking, and CRM tools.
Invoicing without project management
Invoice Ninja has no task boards, no milestone tracking, and no team task assignment features. Agencies using Invoice Ninja for billing manage project execution in a completely separate tool (Asana, ClickUp, or Notion) with no native connection between tasks and invoices.
No live time tracking
Invoice Ninja can receive time entries but does not provide live team timers, idle detection, or real-time timer monitoring. Time must be logged in a separate tool and imported or manually entered into Invoice Ninja for invoice generation.
Self-hosted setup complexity
Invoice Ninja's free plan requires self-hosting on your own server. The hosted Pro plan costs $10/month ($120/year) and removes the DevOps burden: but still leaves project management, time tracking, and CRM as open requirements for the full agency stack.
Why teams are leaving Invoice Ninja for Melororium.
Invoicing only: no Kanban, task management, or team workspace features.
No live timers: time must be logged separately and imported for invoicing.
Free version requires self-hosting; hosted Pro adds $120/year subscription.
Invoice generation connected to native time tracking and project boards.

What is Invoice Ninja? A complete overview for 2026.
Invoice Ninja is an open-source invoicing and billing platform founded in 2014, available as a self-hosted open-source version or a managed cloud product. Covering invoice generation, expense tracking, time logging, vendor management, and payment processing with multiple gateway integrations, Invoice Ninja is one of the most feature-rich free invoicing tools available. The hosted Pro plan costs $10/month. Invoice Ninja's self-hosted option makes it attractive for businesses that want invoice generation without monthly SaaS fees and that have technical resources to deploy and maintain a self-hosted service. The fundamental limitation is scope: Invoice Ninja is a billing tool, not a team project management workspace.
What Invoice Ninja does well
Open-source codebase with unlimited self-hosted deployment: Invoice Ninja's MIT-licensed codebase allows businesses to deploy on their own server infrastructure with no software fees and unlimited clients, invoices, and users. For businesses with technical resources that want professional invoice generation at zero recurring cost, self-hosted Invoice Ninja is a compelling option.
Comprehensive payment gateway support: Invoice Ninja integrates with Stripe, PayPal, Square, Authorize.net, GoCardless, and 40+ other payment gateways: providing flexibility to accept payments via the gateway that offers the best rates for a given business's transaction profile and client base geography.
Recurring invoice and subscription billing management: Invoice Ninja's recurring invoice system automates billing for retainer clients, subscription services, and monthly service agreements: scheduling invoice generation and delivery without manual creation for each billing cycle.
Who Invoice Ninja is best for
Technical small businesses and freelancers who can deploy and manage self-hosted software and primarily need professional invoice generation, payment processing, and expense tracking at minimal software cost: and handle project management and time tracking through informal processes or separate lightweight tools. Invoice Ninja is the right choice when technical self-hosting capability exists and billing automation is the primary requirement.
Where it falls short
Invoicing without project management: Invoice Ninja has no task boards, no milestone tracking, and no team task assignment features. Agencies using Invoice Ninja for billing manage project execution in a completely separate tool (Asana, ClickUp, or Notion) with no native connection between tasks and invoices.
No live time tracking: Invoice Ninja can receive time entries but does not provide live team timers, idle detection, or real-time timer monitoring. Time must be logged in a separate tool and imported or manually entered into Invoice Ninja for invoice generation.
Self-hosted setup complexity: Invoice Ninja's free plan requires self-hosting on your own server. The hosted Pro plan costs $10/month ($120/year) and removes the DevOps burden: but still leaves project management, time tracking, and CRM as open requirements for the full agency stack.
Invoice Ninja pricing in 2026: the real cost for teams.
Before choosing a tool, it's important to calculate the full cost, not only the monthly sticker price, but what your team will spend over 2, 3, and 5 years of continued subscription.
Invoice Ninja · subscription cost
Invoice Ninja self-hosted is free (requires server infrastructure and setup). Invoice Ninja Pro hosted: $10/month ($120/year) for unlimited clients and invoices. Adding Asana for project management ($3,000/year for 10 users) and Toggl for time tracking ($1,080/year): total agency stack $4,200/year.
$600 for Invoice Ninja Pro over 5 years: but the agency stack with PM and time tracking: $21,000 over 5 years.

Agencies switch from Invoice Ninja + Asana + Toggl to Melororium when the three-tool overhead for billing, project management, and time tracking makes a consolidated workspace more appealing than the cost savings of Invoice Ninja's low subscription fee. Melororium's invoice generation connected directly to project time tracking eliminates the export-import step between the time tracker, PM tool, and billing system: for $59/mo flat.
How to switch from Invoice Ninja to Melororium.
Most teams complete the migration in 5–7 days. Here's the process that minimizes disruption while getting your team fully operational on Melororium.
Step 1
Export your data from Invoice Ninja
Export your existing projects, tasks, client contacts, and historical time data from Invoice Ninja as CSV or Excel files. Most project management and billing tools support data export from the Account Settings or Admin panel. Check Invoice Ninja's Help Center for the exact export path: typically found under Settings → Data → Export. Save the exported files as a backup regardless of whether you proceed with the migration.
Step 2
Start the Melororium 14-day free demo
Sign up for the Melororium free demo at crm.melororium.com: no credit card required. You get full Agency plan access for 14 days (15 users, all modules): task tracker, kanban boards, time tracking, client CRM, invoicing, work reports, and the full team workspace. Use the demo to explore the interface and confirm Melororium covers your team's workflow before purchasing.
Step 3
Configure your workspace structure
Set up your client list, project templates, team member profiles, and billing rates in Melororium. Most teams complete the initial workspace setup in 2–4 hours. Import client contacts and project names from the CSV files you exported in Step 1. Configure the modules included with your plan to match your team's specific workflow: kanban boards, time tracking, CRM, and invoicing are ready to use out of the box.
Step 4
Run both tools in parallel for one week
Keep Invoice Ninja active while your team tests Melororium on a live project for one week. This parallel-run period is the most important step: it lets your team build confidence in the new tool without the pressure of a hard cutover, and ensures no in-flight project work gets lost during the transition. Track time in Melororium, manage tasks in Melororium, and let the team ask questions before fully switching over.
Step 5
Purchase Melororium and cancel Invoice Ninja
Once the team is comfortable with the Melororium workspace after the parallel-run week, purchase your plan: from $29/mo (Starter, 4 users) to $59/mo (Agency, 15 users) to $119/mo (Studio, 25 users). Log into Invoice Ninja and cancel your subscription to stop the recurring charge. The migration is complete: your team now runs on Melororium: one flat monthly fee, no seat tax, no price increase as the team grows.
