Engagements, resourcing, timesheets, budgets, and invoices in one AGPL-3.0 platform. The PSA loop without enterprise quotes, per-seat meters, or MSP ticketing you'll never use.
No credit card required. Free forever plan available
Plan the engagement, schedule the people, capture the hours, watch the budget, send the invoice. Worklenz runs that loop in the open source core, cloud-hosted or on your own Docker host.
Consultants log time on engagement tasks. Approved hours accumulate against the budget and flow into native invoicing. The gap where revenue usually leaks, between the timesheet export and the billing tool, does not exist here.
The scheduler shows every consultant's bookings across engagements; utilization reports show whose weeks are billable and whose are bench. Clients follow delivery in their own portal instead of asking your project leads.

The existing open source PSA options are MSP suites or ERP projects. Worklenz is neither.
Consulting, development, design, engineering: project-shaped work with budgets and deadlines. Not helpdesk tickets, not RMM contracts.
Engagement budgets, actuals, and margins without deploying a full ERP like ERPNext and customising it into a PSA over a quarter.
Self-hosted Community has no user cap. Staff up for the big engagement without a licensing conversation.
Utilization, delivery, and profitability across the practice, queryable straight from PostgreSQL when partners want a custom cut.
Bookings and bench time visible weeks ahead.
Native invoicing from approved billable hours.
Deliverables on the engagement, stored on your MinIO or S3.
Your delivery methodology as a reusable engagement template.
Discovery to handover, tracked as stages clients understand.
Practice-wide movement summarised in one daily email.
Search for an open source PSA tool and the results skew MSP: ITFlow (GPL-licensed, built around tickets, assets, and recurring IT contracts) and Alga PSA (a newer MSP platform from Nine Minds). Both are genuinely open source and genuinely good, if you run a managed services business with helpdesk workflows at its center.
Professional services firms, consultancies, dev shops, design studios, engineering practices, work differently: project engagements with budgets, staffing plans, and deliverables. For them the MSP suites carry the wrong primitives. The frequently suggested alternative, customising ERPNext into a PSA, works but is an implementation project of its own.
Worklenz fills the specific gap: an AGPL-3.0 platform whose primitives are engagements, consultants, hours, budgets, and invoices.
An engagement starts as a project, usually from a template carrying your methodology's phases. The resource scheduler books consultants onto it based on real availability. As work proceeds, timers and timesheets capture hours, marked billable or not, and the finance view compares accumulating cost against the engagement budget. Approved time feeds invoices generated inside the platform. Throughout, the client watches progress in their portal instead of requesting status decks.
Every step reads and writes the same PostgreSQL database, which is the entire point of PSA: one version of the truth from staffing call to paid invoice.
Self-hosting is a Docker deployment: clone github.com/Worklenz/worklenz, run ./quick-setup.sh, and the stack comes up on your infrastructure. Community is free with unlimited users; Business ($99/month flat) and Enterprise ($499/month flat) add SSO, custom branding, backups, and support without per-user fees, which matters at consultancy headcounts.
Worklenz Cloud runs the same codebase with a free plan (unlimited users, 3 active projects) and flat-rate paid tiers from $69/month. Firms with client data restrictions often prototype on cloud and move to self-hosted before onboarding the sensitive account.
The realistic open source shortlist and where each fits.
| Worklenz | ITFlow / Alga PSA / ERPNext | |
|---|---|---|
| Built for | Project-based professional services | MSPs (ITFlow, Alga); general ERP (ERPNext) |
| Engagement budgets & margins | Native | Partial; ERPNext after customisation |
| Resource scheduling & utilization | Native | Limited or requires modules |
| Invoicing | Native | ITFlow yes (IT-focused); ERPNext yes |
| Client portal | Included | Ticket portals (MSP tools) |
| Setup effort | Docker, same day | Same day (ITFlow) to weeks (ERPNext as PSA) |
| License | AGPL-3.0 | GPL, AGPL, GPL v3 respectively |

Common questions about Worklenz as an open source PSA
Both, by design. PSA is project management plus the services business around it: resourcing, utilization, budgets, and billing. Worklenz ships that full loop, which is what separates it from open source task trackers.
ITFlow and Alga are built for MSPs: ticketing, asset management, recurring IT contracts. Worklenz is built for project-based services: engagements with budgets, staffed by consultants, delivered in phases. Pick by the shape of your revenue.
For the delivery core (projects, resourcing, time, budgets, invoicing, client visibility), yes, and at a fraction of the cost. Enterprise PSA platforms still go deeper on revenue forecasting and CRM-integrated quoting; Worklenz has CRM on its roadmap and pairs with your existing CRM today.
AGPL-3.0 lets you run, inspect, modify, and self-host Worklenz freely. Internal modifications stay private; only offering a modified version as a public service triggers the requirement to publish changes.
Correct. Community is free at any headcount. The paid self-hosted plans (Business $99/month, Enterprise $499/month) are flat rates for support, SSO, branding, and backup tooling, not per-seat licenses.
Cloud: minutes, on the free plan. Self-hosted: typically the same day, via the Docker quick-setup script. Importing your engagement structure as templates is usually the longest step.
