Task Session | Self-Hosted CRM & Project Management Platform

Task Session is an all-in-one CRM and project management platform built for agencies, freelancers, consultants, and growing teams that want more control over their tools, data, and costs.

Instead of paying for separate CRM, project management, team communication, time tracking, and invoicing tools, Task Session brings everything together in one platform.

The software is self-hosted, so it runs on your own server and gives you full control over your business data. It can also be fully white-labeled with your own company name and branding.

Key Features

CRM & Sales Pipelines: Manage contacts, leads, deals, companies, and sales pipelines.

Projects & Tasks: Create projects, assign tasks, set deadlines, and track progress.

Client Portal: Give clients their own portal to communicate, review work, access files, and stay updated.

Time Tracking & Attendance: Track working hours, attendance, and team activity.

Invoices & Billing: Create, send, and manage invoices directly from the platform.

Team Chat & Discussions: Keep internal communication connected to your projects and tasks.

Email Integration: Connect Gmail, Outlook, or SMTP and track email opens and clicks.

Files, Notes & Documents: Keep important files, notes, and business information organized in one place.

Dashboards & Reporting: Get a clear overview of projects, sales activity, invoices, and team performance.

Task Session is suitable for marketing and SEO agencies, law firms, consultants, software teams, designers, accountants, real estate businesses, and other service-based companies.

There are no per-user charges, so teams can add users without increasing their monthly software costs.

Your server. Your data. Your branding. One platform for managing your business.

The process of preparing an email address for general use or email outreach is commonly referred to as “Warming Up” an inbox, where you take a number of steps to ensure that an email address does not become deactivated, blacklisted, or automatically marked as spam when it begins to send outgoing messages to other recipients.

Warming Up an email inbox essentially is recreating the way a typical person will use an email address. Just by using your email address normally, you are ‘warming up’ your inbox by sending outgoing mail to other existing users. When you are reading your emails, starring/favoriting certain messages, and engaging in email threads with multiple other email addresses, you are building up your domain reputation in a way that shows that your account is being controlled by a real human being and is not being used to send out unsolicited emails that are trying to mislead/scam/defraud any other real people using their email inbox.

Questions & Answers

As answered by people managing Task Session and Warmup Inbox.

What makes your product unique?

Task Session's answer

Task Session puts both halves of client work in one place: the CRM where leads and clients live, and the workspace where the work actually gets delivered.

Most small teams pay for a CRM and a project tool separately, then spend the week copying data between them. Here a lead becomes a client, the client becomes a project, the project produces timesheets, and those timesheets turn into an invoice - without re-entering anything.

It is also self-hosted, so the whole system runs on your own server and your client data, contracts and invoices never leave it.

How would you describe the primary audience of your product?

Task Session's answer

Small agencies, studios and freelancers who work directly with clients - digital and marketing agencies, design and development shops, consultants and service businesses, typically between 2 and 50 people.

The usual profile is a team that has outgrown spreadsheets, WhatsApp groups and a shared inbox, but does not want an enterprise suite or five separate subscriptions. They need client records, project delivery, billable hours and invoicing in one place, and they care about hosting it themselves so the client data stays on their own server.

What's the story behind your product?

Task Session's answer

Task Session came out of the mess of running agency work across too many tools.

Leads sat in one CRM, projects in a second app, hours in a third, invoices in a spreadsheet, and client files were scattered across email. Every status update meant checking four places, and every invoice meant reconstructing the month from memory. The tools were fine on their own - the gaps between them were the problem.

So we built the workflow we actually wanted: contact to project to timesheet to invoice, in one system, running on our own server. We used it day to day for our own clients first, and it worked well enough that we packaged it up for other agencies and freelancers dealing with the same pile of disconnected apps.

Why should a person choose your product over its competitors?

Task Session's answer

Three reasons: scope, ownership and cost.

Scope: CRM, projects, tasks, time tracking, attendance, invoicing, a client portal, chat and file management ship together. A small agency does not have to stitch four or five subscriptions into one workflow and then keep them in sync.

Ownership: Task Session is self-hosted, so your client list, project history and invoices sit on infrastructure you control. That matters when you are holding other people's data.

Cost: it is not a per-seat monthly bill that grows every time you hire, so adding a designer or an assistant does not add another recurring line item across three tools.

The trade-off is honest. If you want a hosted enterprise suite with a large app marketplace, a bigger platform will suit you better. Task Session is for teams that want the whole client workflow in one place, on their own server.

Which are the primary technologies used for building your product?

Task Session's answer

Task Session is a self-hosted web application built with PHP on the Laravel framework, with MySQL for data storage. The interface is standard HTML, CSS and JavaScript, responsive across desktop and mobile browsers.

The stack is deliberate: it runs on ordinary LAMP-style shared or VPS hosting, with no containers, managed services or special infrastructure required. Most agencies already have hosting that runs PHP and MySQL, so installing Task Session on their own server is straightforward.
