Akaunting vs Invoice Ninja 2026:
Open-Source Accounting vs Open-Source Invoicing

The Akaunting vs Invoice Ninja comparison sits at a unique intersection in the software market: both platforms are open-source, both offer free tiers, and both serve small businesses and freelancers — yet their philosophies diverge sharply. Akaunting is built as an accounting platform first, with invoicing as one component of a broader financial management system. Invoice Ninja is built as an invoicing and billing platform first, with accounting features layered in as the product has matured. Understanding that structural difference is the most important starting point for any business choosing between them. For context on how both platforms fit within the wider market, our guide to free accounting software covers the full landscape of no-cost and open-source options available in 2026.

Pricing & Plans

Both platforms offer genuinely free tiers, but the conditions attached to each free plan differ meaningfully — and the upgrade paths diverge in structure and cost.

Akaunting pricing (cloud, monthly billing): Akaunting’s cloud plans are tiered by the number of companies, users, invoices, and bundled apps. The Standard Cloud plan costs $12 per month (or $8 per month billed annually) and covers one company, one user plus one accountant seat, up to 1,000 invoices, and four bundled apps. The Premium Cloud plan costs $36 per month (or $24 per month annually) and extends to ten companies, ten users, 10,000 invoices, ten bundled apps, and adds double-entry accounting, bank feeds, expense claims, roles and permissions, and a client portal. The Elite Cloud plan costs $84 per month (or $56 per month annually) and scales to thirty companies, thirty users, and thirty bundled apps, while adding estimates, payroll, projects, and inventory. An Ultimate Cloud plan is available with custom pricing for larger organisations. Self-hosted Akaunting is free to download and install on your own server — all core features are available, but premium apps from the Akaunting App Store must be purchased separately for the self-hosted version. A free trial is available on all cloud tiers.

Invoice Ninja pricing (effective January 2026): Invoice Ninja updated its pricing at the start of 2026. The free plan remains free and supports up to 20 clients with unlimited invoices, four invoice templates, and auto-billing — making it one of the most capable free invoicing plans available. The cloud-hosted paid tiers are structured by user count: the two-user plan costs $18 per month, scaling through five users at $32 per month, ten users at $54 per month, twenty users at $84 per month, and larger teams at higher price points. Annual billing is available at approximately 20% savings. For self-hosted deployments, Invoice Ninja is free and open-source — all Enterprise features including unlimited users and clients are available with no subscription required. An optional white-label licence to remove Invoice Ninja branding from client-facing documents costs $40 per year for self-hosted installations. The free plan limits users to one account, four templates, and the Invoice Ninja watermark on client documents.

Self-Hosting & Deployment

Both platforms are open-source and self-hostable, but the technical demands and deployment experience differ between them.

Invoice Ninja is built on Laravel (PHP) and offers a Flutter-based desktop and mobile interface alongside a React web interface. It is available as a Docker image, which significantly simplifies self-hosted deployment — a Docker-comfortable user can have a running instance in fifteen to twenty minutes. The self-hosted version includes all Enterprise features with no client or user limits, making it the most generous self-hosted offering in its category. The trade-off is a steeper initial setup for users unfamiliar with server management or Docker; the self-hosted route is not recommended for users without some command-line experience. Invoice Ninja v5 (the current version as of 2026) was a ground-up rewrite from v4 and is actively maintained with regular updates. The open-source community around Invoice Ninja is active, and the codebase is publicly available on GitHub.

Akaunting is also built on Laravel and is available for self-hosting. The installation process is documented and manageable for users with basic server administration skills, though it is not as streamlined as Invoice Ninja’s Docker path. The self-hosted Akaunting core is free and includes the base accounting features — invoicing, expense tracking, contacts, and basic reporting. However, the modular architecture means that more advanced features (double-entry accounting, inventory, payroll, projects, and CRM) are sold as separate apps through the Akaunting App Store and must be purchased individually for self-hosted installations, even though these same features are bundled into the higher cloud tiers. This modular model gives self-hosted users precise control over what they pay for, but it means the effective cost of a fully-featured self-hosted Akaunting installation can exceed the headline “free” price depending on which apps are needed.

Invoicing & Payments

Invoice Ninja leads this category, and the gap in invoicing feature depth is one of the most practically significant differences between these two platforms for businesses that primarily bill clients.

Invoice Ninja provides unlimited invoices on all plans — including the free tier — with support for recurring invoices, automatic late payment reminders, customisable invoice templates, quote and estimate creation, and a client-facing portal where clients can view, approve, and pay invoices directly. Payment gateway support is exceptionally broad, covering Stripe, PayPal, Square, Braintree, Authorize.net, and more than thirty additional gateways via native integrations. Auto-billing and subscription billing are supported for recurring client relationships. A standout feature is Invoice Ninja’s voice command capability, which allows users to create and send invoices using simple voice instructions — a unique feature not available in Akaunting. The free plan’s 20-client cap is the primary practical limitation; beyond that, the invoicing feature set is competitive with paid alternatives in the market.

Akaunting offers professional invoicing with customisable templates, recurring invoices, and multi-currency support across all plans including Standard. The client portal — which allows clients to view and pay invoices — is available from the Premium Cloud plan at $24 per month annually, not on the entry-level Standard plan. Payment integrations include Stripe and PayPal natively, with additional gateway support available through the App Store. For a business whose primary need is clean, professional invoicing with direct client payment links, Akaunting covers the essentials well on the Standard plan. The invoicing workflow is clean and accessible, though it does not match Invoice Ninja’s depth of billing-specific features such as the breadth of payment gateways or the voice command functionality.

Accounting & Reporting

Akaunting wins this category, and it reflects the fundamental difference in each platform’s design philosophy: Akaunting is an accounting system; Invoice Ninja is an invoicing system with accounting features.

Akaunting’s cloud plans include structured accounting from the outset. The Standard plan covers income and expense tracking, unlimited reports, and multi-currency support. The Premium plan adds full double-entry accounting with a chart of accounts, balance sheet, general ledger, trial balance, and bank feeds — features that Invoice Ninja does not offer natively at any tier. The Elite plan adds payroll, inventory management, projects, and estimates. The App Store model means that even self-hosted users can purchase individual accounting modules like double-entry, inventory, or CRM as needed. For a small business that wants a proper accounting foundation — accrual accounting, reconciled bank feeds, and professional financial statements — Akaunting’s Premium Cloud plan at $24 per month annually delivers genuine accounting depth. The multi-company support on Premium and Elite plans is also a structural advantage for accountants or business owners managing multiple entities.

Invoice Ninja’s accounting capabilities are functional for basic business tracking but are not designed to replace a dedicated accounting platform. The system tracks income through invoices and expenses through its expense module, and basic profit and loss visibility is available. However, Invoice Ninja does not offer full double-entry accounting, bank reconciliation, a chart of accounts, or a balance sheet natively. For freelancers and service businesses whose accounting needs are limited to knowing what they have invoiced and what they have spent — and who pass their records to an accountant at tax time — Invoice Ninja’s reporting is sufficient. For businesses needing GAAP-compliant accounting records, a balance sheet for financing purposes, or multi-entity financial reporting, Akaunting is the necessary choice.

Time Tracking & Projects

Invoice Ninja includes built-in time tracking on all plans, including the free tier, making it the stronger choice for freelancers and consultants who bill hourly.

Invoice Ninja’s time tracking allows users to log hours against specific clients and projects, with a built-in timer for real-time tracking. Hours can be pulled directly into invoices at the end of a billing period, with detailed time entries listed on the invoice automatically. The project management layer in Invoice Ninja includes task management, project budgeting, and Kanban boards — a level of project tooling that goes beyond what most pure accounting platforms offer. For a freelancer or small agency that tracks billable hours and needs those hours to flow cleanly into client invoices, Invoice Ninja’s time-to-invoice workflow is one of its strongest practical advantages.

Akaunting offers a Projects app that covers task management, time tracking, and milestone tracking — but it is available as a paid add-on, bundled from the Elite Cloud plan at $56 per month annually, or purchasable separately for self-hosted users. For businesses on the Standard or Premium Cloud plans that need time tracking, the Projects app must be purchased additionally. This means Akaunting’s time tracking comes at a higher price point than Invoice Ninja’s, where it is included in the free plan. For businesses that do not need project and time tracking — those billing fixed-price engagements or selling products — this distinction is irrelevant. For hourly-billing professionals, the cost difference is meaningful.

Integrations & Ecosystem

Invoice Ninja has a broader native integration set for billing-adjacent tools; Akaunting’s App Store gives it more extensibility for accounting-adjacent features.

Invoice Ninja integrates natively with over thirty payment gateways — more than any comparable platform at its price point. It also connects with Zapier and Integromat (Make) for workflow automation, extending its reach to thousands of additional apps. API access is available on paid plans and the self-hosted version, enabling custom integrations for technical users. For a freelancer or agency that uses Stripe for payments, Zapier for automation, and wants to connect their invoicing to a CRM or project management tool, Invoice Ninja’s integration coverage is strong. The open-source nature of the platform also means community-developed integrations exist for niche tools.

Akaunting’s integration ecosystem is built around its App Store, which offers over 100 apps covering accounting modules, payment gateways, bank connections, CRM, payroll, inventory, and more. Key integrations include Stripe, PayPal, Mollie, GoCardless, and a range of regional payment processors. Bank feed connections are available on the Premium plan. The App Store model is a double-edged sword: it makes the base platform very clean and lightweight, but it means that integrations which are bundled natively in competitors require a separate purchase in Akaunting. The open API allows for custom integrations, and the Laravel-based architecture makes it accessible to developers building on top of the platform.

Feature Scores

Full Feature Comparison

Here is a side-by-side breakdown of how Akaunting and Invoice Ninja compare across the features that matter most to small businesses, freelancers, and service-based operators in 2026. For broader context on how these platforms compare against the wider field, see our guide to invoicing software for small businesses.

Support & Reliability

Akaunting provides ticket-based support across all cloud plans, with access linked to subscription tier. The platform has been operating since 2017 and serves hundreds of thousands of users globally, which gives it a reasonable track record of stability. Community support through the Akaunting forum and documentation is available for self-hosted users. User reviews in 2025 and 2026 highlight some inconsistency in support quality, particularly for self-hosted premium app purchases — a pattern worth noting for businesses considering the self-hosted premium app path. The cloud infrastructure uses 256-bit SSL encryption with hourly, daily, weekly, and monthly backups, which represents a solid baseline for a small business accounting platform.

Invoice Ninja offers community support via its forum and documentation, with paid support available for cloud subscribers. The open-source development community is active, with regular updates to the v5 codebase. Because the self-hosted version is free and fully featured, there is a large pool of community-contributed documentation, tutorials, and troubleshooting resources for technical users. For businesses that rely primarily on community support, Invoice Ninja’s active GitHub presence and forum community are genuine assets. For businesses that need responsive, professional support with guaranteed response times, neither platform at the entry level matches the dedicated support available from paid-first platforms like QuickBooks or FreshBooks — a consideration worth weighing for any business where the accounting tool is operationally critical.

Who Should Use Which?

Our Final Verdict

In the Akaunting vs Invoice Ninja comparison, the right platform depends on whether your primary need is accounting structure or invoicing power. Invoice Ninja is the stronger invoicing tool: its free plan is the most generous in its category, its self-hosted option delivers Enterprise features at near-zero cost, and its payment gateway breadth and time tracking integration are genuine competitive advantages for freelancers and service businesses. Akaunting is the stronger accounting tool: double-entry accounting, bank feeds, reconciliation, and multi-company support give it a structural depth that Invoice Ninja does not offer natively, and its modular App Store model allows businesses to expand into payroll, inventory, and CRM as they scale.

For a freelancer or solo operator whose primary need is getting paid quickly and professionally, Invoice Ninja’s free plan covers the workflow without any cost. For a small business that needs proper financial records — double-entry bookkeeping, reconciled bank statements, and clean tax-ready accounts — Akaunting’s Premium Cloud plan at $24 per month annually delivers genuine accounting value at a price point that compares favourably with alternatives like Wave vs QuickBooks or FreshBooks vs Wave. Both platforms sit firmly in the open-source, privacy-respecting end of the market — a meaningful differentiator for businesses that value data ownership and transparency. For a complete view of the small business accounting software landscape, our guide to invoicing software for small businesses covers both platforms within a broader competitive context.

We tested both platforms through a standard small business workflow — creating client profiles, sending invoices, logging expenses, running a profit and loss report, and exploring the self-hosted setup path for each. Invoice Ninja completed the full invoicing flow faster and with more payment options; Akaunting produced more complete financial records with bank reconciliation and double-entry accounting available. Neither platform’s free or entry tier covers every business need — the upgrade path matters as much as the starting point when evaluating long-term fit.
