The operating system
for client work.
Stackon is client work management software for agencies and service businesses, combining client portals, project management, requests, deliverables, feedback, approvals, retainers, and billing in one connected workspace.
Client work is more complicated than a task list.
A client asks for something. It needs scoping, assignment, delivery, review, feedback, revisions, approval, invoicing, and ongoing retainer tracking. Yet most agencies manage this across 6+ disconnected silos.
Siloed Tools = Constant Context Loss
The Operating System for Client Work
The problem isn't that businesses don't have enough software.
It is that they have too much of it.
A service business can easily end up using 8 different tools for PM, chat, file sharing, approvals, CRM, proposals, and billing. Each tool works on its own, but context shatters the moment work moves between them.
“The client relationship and the work being delivered to that client should live in the same system.”
That means your team can understand the client, the request, the project, the deliverables, the conversations, the approvals, and the commercial relationship without stitching the story together manually.
What is client work management software?
Client work management software is designed to manage the complete workflow between a business and its clients - from requests and projects through delivery, feedback, approvals, and ongoing client work.
Project management software was built primarily to help internal teams manage internal tasks. CRM software was built primarily to manage sales pipelines. Billing software was built to send invoices. Client portal software was built to provide a login screen.
All of those things are useful, but client work doesn't happen inside one of those isolated categories. It happens between them.
A request becomes a project. A project produces deliverables. A deliverable creates feedback. Feedback becomes a revision. A revision becomes an approval. An approval triggers billing. The client relationship continues into an ongoing retainer.
That entire connected chain is client work - and that is what Stackon is built around.
One connected workflow.
Instead of treating these steps as separate processes across separate tools, Stackon connects them into a seamless flow.
More than a client portal.
A client portal is useful, but a portal alone does not solve client work. Clients need a simple, polished place to work with your business. Your team needs a powerful operational workspace behind that experience.

Built for businesses that deliver work to clients.
Different services. Different clients. Different deliverables. But the same fundamental challenge: how do you organize work between your team and your clients without making the process harder than the work itself?
Marketing Agencies
Manage client requests, campaigns, content deliverables, visual approvals, and monthly retainers from one workspace.
Design Agencies & Creative Studios
Keep brand projects, files, feedback, proofing, revision rounds, and sign-offs connected to the client.
Development Agencies & Studios
Turn feature requests into structured projects, coordinate delivery milestones, and communicate without losing context.
Consultancies & Advisory
Organize client engagements, executive deliverables, communication, formal approvals, and recurring retainers in one place.
Freelancers & Independent Pros
Run client requests, projects, deliverable reviews, billing, and communication without assembling a complex software stack.
Productized Service Businesses
Standardize how clients request, receive, review, and continuously purchase recurring design or development services.
Your client should never have to understand your software stack.
They don't care which internal task tracker you use. They don't care which cloud drive hosts their files. They want one simple answer to one simple question:
Frictionless Simplicity
A modern, polished portal with clear action items. They know exactly what is being worked on, what is awaiting their review, and what has been completed.
We believe software should follow the way work actually happens.
Five core principles that guide how we design, build, and support Stackon.
Clear over complicated
SimplicityWe prefer straightforward interfaces, familiar terminology, and obvious actions over dense configurations that require training.
Connected over fragmented
Unified DataFeatures should work together natively. A client request should flow naturally into a project, a deliverable, an approval, and an invoice.
Client-first without sacrificing operations
Dual-SidedYour clients deserve a clean, modern experience. Your team deserves powerful operational tools behind it. You should not have to choose one over the other.
Flexible without becoming chaotic
AdaptableEvery service business operates differently. Stackon adapts to your workflow while keeping the underlying system predictable and clean.
Useful over impressive
UtilityWe do not build vanity features that look good in demos but add friction in practice. Every capability exists to help you deliver real client work.
Meet the founder.
Vishal Raghuwanshi
Stackon was founded by Vishal Raghuwanshi around a straightforward observation: client work is still unnecessarily fragmented. The tools businesses use to manage clients, projects, communication, deliverables, and billing often operate as separate systems, creating friction for the people doing the work and the clients receiving it.
“I believe the best software should make complicated work feel simple. Client relationships are complicated enough without forcing teams to manage every part of the relationship in a different application.
Stackon started with a simple question: What would client work look like if requests, projects, deliverables, feedback, approvals, communication and billing were designed to work together from the beginning?
That is what we're building. Our goal is not to build software for software's sake. It is to give service businesses a better way to organize the work they already do every day - and give their clients a better experience while doing it.”
What Stackon is - and what it is not.
Clarity of scope is how great software stays fast, reliable, and focused on solving the real problem.

Not Trying to Rebuild the Entire Internet
Stackon does not need to replace every specialist tool your team already loves:
One system. One client relationship.

Building Stackon for the long term.
We're not interested in building a temporary collection of features around whatever happens to be trendy this year. Client work is an enduring discipline.
The way agencies and service businesses communicate with clients will continue to change. Software will evolve. AI will accelerate production. Teams will become more distributed. Clients will expect faster turnaround times and greater transparency.
But one thing will remain constant: businesses will still need to deliver great work to their clients.
Stackon is built around that fundamental relationship. The tools may change, but the mission remains clear: make client work easier to run.
