Project software for agencies: what matters
Updated: 2026-09
Agencies face four kinds of tool: plain task management, classic project management, integrated agency software, and self-assembled combinations of separate tools. What decides the choice is whether time tracking and billing connect directly to the project data.
Agencies have a requirement many project tools do not cover: the project work is at the same time the basis for billing. Recording time in one system and billing in another loses time and accuracy at exactly that seam.
The four common approaches differ mainly in how tightly that connection is represented — and how much configuration is needed before the tool is useful.
The options at a glance
Plain task management
Best for: Small teams mainly needing an overview of open items.
Quick to set up and easy to understand. Time tracking, resource planning and billing are generally absent and must be kept elsewhere.
Classic project management
Best for: Teams with structured projects and schedules.
Covers planning and progress well. The step to billing is usually not provided for, and configuration can be laborious.
Integrated agency software
Best for: Agencies where project work and billing connect.
Joins project, time and invoice in one flow. In exchange the choice is narrower and the feature set must fit the working model.
A combination of separate tools
Best for: Teams with very particular workflows and the capacity to connect them.
Maximum freedom of choice. The price is interfaces, double entry and the question of who maintains the connection.
When an alternative is the better choice
Your workflows are so particular that only your own combination fits.
An established billing system already exists and is not to be replaced.
You need only a task overview and bill at a flat rate.
FAQ
What is the most important criterion for agencies?
Whether time tracking and billing connect to the project data. That seam produces most of the avoidable effort.
Is a combination of separate tools worth it?
If workflows are very particular and somebody maintains the connection permanently. Without that capacity, double entry appears that nobody then removes.
How much configuration makes sense?
As little as possible at the start. Tools requiring extensive setup before first use are, in experience, adopted less often.
What about the Swiss QR invoice?
For Swiss agencies it is a hard criterion. Tools without support force an extra step on every invoice.
Flenio
Integrated PSA connects time tracking, resource planning and Swiss QR invoicing with the project data — exactly the seam where agencies otherwise lose time.
Four views on one data set mean project leads and the team can see the same data differently without maintaining it twice.
