The official Debian image includes Chrome, so high PDF volume adds browser CPU/RAM demand.
Invoice-heavy businesses.Invoice Ninja Hardware Requirements: RAM, CPU, Database & Storage
Plan Invoice Ninja hardware for RAM, CPU, MySQL or MariaDB, PDF generation and storage, with practical ZimaOS custom-install recommendations.
Invoice Ninja requirements at a glance
Invoice Ninja v5 self-hosting uses a PHP application plus MySQL/MariaDB and web-server services. Current official docs publish software prerequisites rather than a numerical CPU/RAM/disk minimum.
- RAM
- No numerical official minimum published. The app, database, PHP-FPM, web server and PDF-generation browser share host memory.
- CPU
- No numerical official core minimum. PDF generation, imports, reports and background jobs create the more noticeable CPU bursts.
- PHP
- Current self-host server requirements specify PHP 8.2 plus required extensions.
- Database
- Current requirements: MySQL 5.7+ or MariaDB 10.3+, or a compatible managed MySQL tier.
- Docker
- Invoice Ninja provides official Debian and Octane container options; the Debian image includes Chrome for PDF generation.
- Best Zima starting point
- ZimaBoard 2 832 is a strong small-business starting point; use 16 GB when PDFs, imports and other business apps share the host.
From official requirements to the right setup
Size Invoice Ninja as a PHP/database business app with scheduled jobs, PDFs and financial-document persistence.
-
Official requirements
Start with current server requirements: PHP 8.2, MySQL 5.7+ or MariaDB 10.3+, and nginx or Apache with HTTPS.
-
Confirm your needs
Estimate users, invoices, reports, imports and PDF generation. Official Debian containers include Chrome, which adds a browser process to the workload.
-
Leave room to grow
Persist application storage, logos/files and the SQL database, and maintain independent backups before updates.
-
Run it on ZimaOS
On ZimaOS, use Install Custom App with Invoice Ninja's official Docker Compose setup, configure APP_URL/APP_KEY and database credentials, and secure the instance with HTTPS.

- Accounting users
- Invoices/quotes
- PDF generation
- Imports/reports
- MySQL or MariaDB
- Persistent app storage
- Backup retention
- Other business apps
Official minimum requirements
Invoice Ninja's current official documentation publishes software prerequisites but no numerical host hardware minimum.
Do not invent a 2 GB or 4 GB official minimum. Whole-host sizing must include the SQL database, PHP-FPM/web stack and PDF-generation browser.
| Requirement | Official minimum | What this supports |
|---|---|---|
| RAM minimum | No numerical official minimum published | App, database, web stack and Chrome/PDF workload share memory. |
| CPU minimum | No numerical official minimum published | PDFs, imports and reports affect CPU demand. |
| Storage minimum | No numerical official minimum published | Database, documents, logos/files and backups drive capacity. |
| PHP | PHP 8.2 | Current manual self-host requirement. |
| Database | MySQL 5.7+ or MariaDB 10.3+ | Current self-host requirement. |
| Web server | nginx or Apache with HTTPS | Current self-host requirement. |
When to upgrade your hardware
Invoice Ninja should scale when PDF generation, reporting or database activity creates sustained host pressure.
PDF generation becomes frequent
Reports and imports grow
Documents and backups expand
Larger financial datasets increase PHP and SQL workload.
Long-running multi-user deployments.Invoices, logos, attachments and database backups create long-term storage growth.
Businesses retaining years of financial records.Plan hardware growth with confidence
Scale Invoice Ninja around SQL responsiveness and business-document durability.
Use SSD-backed MySQL/MariaDB storage
Fast durable SQL storage improves invoice/report responsiveness.
Use SATA/NVMe on ZimaBoard 2 or SSD tiers on ZimaCube 2.Use 8 GB for a small-business all-in-one host
Provides comfortable room for Invoice Ninja, SQL and PDF services.
ZimaBoard 2 832.Move to 16 GB for heavier PDF/report workloads
Extra RAM helps Chrome/PDF generation, SQL cache and other business apps coexist.
ZimaBoard 2 1664.Use ZimaCube for broader document/backup retention
Choose a larger platform when business files and backups dominate storage.
ZimaCube 2 Standard.Can it run on ZimaOS?

Zima Blade Little yet Powerful
Maybe I am not digital natives but I live with PCs since 12 years old in 1984 when IBM PC clone come to my home. Many years have passed and many operating system I've tried. For me Zima blade and CasaOS was a quantum leap for home PC enthusiast and server lab machine to make me stay curious and relevant for this era.

Very good!!
I use ZimaCube Pro as 5th Proxmox cluster node. It runs several VMs and containers, including a VM with GPU passthrough to run a self-hosted LLM. A specific LXC container runs a Samba server for NAS capabilities using four of six RAID 6 SATA HDDs with ZFS.
★★★★★
Great innovation for mini server!
It is very useful and makes a powerful mini server for many purposes, including university and college students in engineering and electronics. Thank you so much for making this server.

Avaliação ZimaBoard 2
Construí um servidor de uso pessoal. O desempenho está muito bom e funciona perfeitamente onde quer que eu esteja. A surpresa é não dependermos de grandes estruturas para termos nosso próprio servidor de dados. Como iniciante, estou gostando bastante do ZimaOS, pois ele é simples e eficiente.
