Problem
When multiple companies collaborate on common projects, scattered emails and files lead to confused versions and loss of critical information.
Coordinate complex projects with clients, partners, and suppliers in a single secure area.
At a glance
Project Collaboration Platform is custom software for General and Professional Services companies. Coordinate complex projects with clients, partners, and suppliers in a single secure area. It centralizes data, reduces manual work, and creates an operational flow shaped around how the team actually works.
When multiple companies collaborate on common projects, scattered emails and files lead to confused versions and loss of critical information.
A shared project workspace with granular permissions, automatic file versioning, and transparent activity timeline.
Secure collaboration with end-to-end encryption
The structure starts from the operational problem: When multiple companies collaborate on common projects, scattered emails and files lead to confused versions and loss of critical information.
Records, history, documents, and operational statuses are collected in one environment with role-based permissions.
We activate reminders, alerts, assignments, and automated steps to reduce delays, forgotten tasks, and repetitive work.
A solution like this can usually connect with Calendars, Document archive and Time tracking. The real connections are defined around the tools already in use.
This outcome is translated into measurable modules, rules, and operational interfaces.

Coordinate complex projects with clients, partners, and suppliers in a single secure area. In practice, it helps solve this scenario: When multiple companies collaborate on common projects, scattered emails and files lead to confused versions and loss of critical information.
It is useful when the process has specific rules, distributed data, multiple roles, or connections that standard software does not cover well.
The base can include workflow shaped around the real process, centralized and searchable data, automations and notifications and typical integrations, plus specific modules defined during process analysis.
Typical integrations include Calendars, Document archive, Time tracking and CRM/ERP. During analysis we define which connections to use around the existing tools and operating process.
The path starts with "Audit projects, tasks, and documents" (1 week to map projects, tasks, and documents, involved data, and operational constraints.) and continues with "MVP board and shared archive" (4-6 weeks to release board and shared archive with pilot users and real data.).
It starts with an analysis call, workflow mapping, priorities and core modules, followed by a technical plan with timeline and budget.
In-depth guide
Every agency, consulting firm, or IT company faces the same problem: you need to share documents, tasks, and updates with clients, suppliers, and external freelancers — but you cannot give them access to your internal systems. The result is a chaos of emails, Dropbox links, WhatsApp chats, and files multiplying in uncontrolled versions. At Graffico, we build custom external collaboration platforms for managing projects with external stakeholders: isolated workspaces per client, encrypted file sharing, integrated chat, a complete audit log, and granular permissions — without ever exposing internal company data.
The external collaboration platform we develop is designed for organisations that work daily with stakeholders outside the company boundary and need a secure, traceable, and professional channel:
This is not a simple cloud storage: it is a project collaboration platform with access control, integrated communication, and audit log — built to fit your sector and your workflow.

Emails with attachments, links shared on WhatsApp, Dropbox or Google Drive folders shared with personal addresses: these tools offer no access control, do not record who saw or downloaded what, and do not allow granular access revocation. In the event of a data breach or dispute, there is no documentable trace of who had access to what and when.
You sent a confidential commercial proposal to a client. Was it read? By whom? Was it downloaded? With traditional systems, these questions go unanswered. Our platform records every access, every download, every modification — with precise timestamps and the user's IP address.
"Proposalv3FINALforreal.docx" is a universal problem. Without a versioning system, collaborators work on different versions of the same document, generating confusion, errors, and rework. Our versioning system tracks every change and allows you to return to any previous version.
Giving an external supplier access to an entire shared folder often means giving them visibility into other clients' data or irrelevant internal information. On the other hand, creating excessively restricted access means everyone wastes time with constant requests. The granular permissions system solves this problem with surgical precision.
Many companies use internal systems like Jira, Confluence, SharePoint, or proprietary ERPs. Giving external access to these systems means opening a window into internal infrastructure, with security risks, licensing complexity, and compliance issues. The external collaboration platform creates a secure layer between internal and external, without ever exposing core systems.

Each project lives in its own isolated workspace. There is no possibility of one client seeing another client's projects:
Activity management is the heart of project collaboration:
Secure document sharing is one of the core features:
Version control eliminates the "filefinalv2_REAL" chaos:
Contextualised communication reduces emails and keeps the conversation close to the work:
The permissions system is what distinguishes a professional platform from a simple cloud:
Predefined roles:
Granular permissions:
The audit log is the feature that makes the platform a legally reliable tool:
The notification system keeps everyone updated without requiring constant platform monitoring:
Collaboration with external parties involves personal data processing that must comply with Art. 32 GDPR (technical and organisational measures appropriate to the risk):
Technical measures implemented:
Organisational measures:
For organisations operating in critical sectors (energy, transport, healthcare, digital infrastructure, financial services), the NIS2 Directive (EU Directive 2022/2555) imposes specific security measures for supply chain and third-party collaboration:
Integration with corporate identity systems is fundamental for security and user experience in large organisations:
For agencies and consulting firms that want to present the platform under their own brand:
---
Project opening: The internal project manager creates a workspace for the new client in 2 minutes. Assigns internal team members. Invites client contacts via email and, if the project involves suppliers, also supplier contacts — with different roles.
Kickoff: The whole team accesses the platform. Brief documents, signed contracts (if the workflow requires it), and technical specifications are uploaded. The Kanban board is created with project tasks. The client sees only the columns relevant to them.
During the project: The internal team works on tasks. Files are uploaded to the shared folder. The client can comment, approve deliverables, ask questions in the workspace chat. The supplier accesses only the tasks and folders within their remit. Every action is tracked in the audit log.
Deliverables and approvals: When a deliverable is ready, it is uploaded to a specific folder. The client receives a notification, enters the platform, views (or downloads, if permitted), and leaves feedback in the task thread or chat. Formal approval can be managed with a digital signature mechanism or explicit tracked confirmation.
Project closure: The workspace is archived. Documents remain accessible to internal members for the configured period. At the end of the retention period, client data is automatically deleted with the deletion recorded in the audit log. If the client requests deletion of their data before the deadline (Art. 17 GDPR), the procedure is executed manually with documentation.

Tools for external collaboration exist (Basecamp, Notion, ClickUp with guest access, Huddle, SharePoint Extranet). Why a custom system?
Limitations of generic tools:
