Project management connected directly to the client.
Generic project tools only track internal to-do lists. Stackon connects your tasks, deliverables, visual client reviews, retainer hours, and milestone billing in one continuous loop.

Why ClickUp, Asana, and Monday
create more work for agencies.
Traditional project management tools are isolated task trackers. They don't know what a client is, what a deliverable review looks like, or how retainer hours burn.
- ✕Tasks end in text comments. You have to export files, attach them to emails, and wait days for replies.
- ✕Clients get confused if invited into your internal boards with 400 micro-subtasks.
- ✕No visual proofing. You must buy and manage separate tools like InVision or Frame.io.
- ✕Retainers and invoices live in separate tools. You manually calculate hours in spreadsheets.
- ✓Tasks attach reviewable files directly to the client's branded portal with 1 click.
- ✓Dual visibility keeps internal subtasks private while publishing clean milestones.
- ✓Native point-and-click pin comments on images and multi-page PDFs inside the task.
- ✓Tasks automatically deduct from monthly retainer budgets and trigger Stripe milestone payments.
Built for how client work actually gets done.
Everything your team needs to manage client delivery smoothly from intake to final sign-off.
Tasks produce reviewable deliverables, not just text
In generic task managers, tasks end with a comment like 'done, check your email'. In Stackon, completing a task attaches the image or PDF deliverable directly to the client's portal for visual review.
Keep internal work private while sharing clean milestones
Your team can brainstorm, leave rough notes, track subcontractor costs, and manage messy subtasks behind the scenes. Clients only see clean project milestones and deliverables ready for their review.
Turn client intake briefs straight into project plans
When a client submits a new project request or intake form, Stackon turns the scope into a structured project with assigned team members, milestones, and deliverable dates.
Tasks automatically track against monthly retainer hours
Every hour logged or deliverable completed automatically updates the client's monthly retainer balance. Visual burn meters show both you and your client exactly where the budget stands.
Sign-offs that protect your scope before the next phase
Set up required client sign-offs between milestones. The next project phase won't begin until the client officially reviews and approves the current deliverables.
See who is busy and what is blocked by client feedback
Get a clear cockpit view of all your team members, active client deadlines, and items waiting on client approvals. Rebalance tasks with a single click.
