The task owner hears it's
due — before the Gantt
starts slipping.

A project plan only works if people act on time. Fast Project Management Software fires WhatsApp, email and SMS alerts from real project events — a task assigned, a due date approaching, a milestone reached, a project PR or bill waiting on approval, a task running behind — so the assigned user acts, the owner and customer stay informed, and the manager sees slippage before it spreads down the schedule.

Three channels, one rulebook

WhatsApp is where the team lives.
Email & SMS carry detail and reach.

All three channels fire from the same project events, so you choose the medium per alert — a WhatsApp thread to the assigned user, a one-line SMS when a task is due today, a full email with the approval detail for the record. One event, your choice of channels.

Where the project team is
WhatsApp alerts
The conversational channel site engineers, task owners and managers already check all day: task assignments, due-date reminders, milestone confirmations and progress prompts land in the thread they act from — project, task and what's needed, in a message they don't have to log in to read.
Task assignments Due-date reminders Milestone confirmations Read on site
Detail, record & reach
Email & SMS alerts
Email carries the full picture — project, task, approval detail, amount, due date — and doubles as an approval and audit paper trail for the ISO auditor. SMS gets read anywhere on site or in the field, with or without data — the channel of choice for a task due today or a bill awaiting sign-off.
Full project context Approval paper trail Reads anywhere Time-critical approvals
How it works

Project events fire alerts.
Alerts drive the response.

No one has to remember to notify anyone. The project's own lifecycle — a task assigned, a due date, a milestone, a project PR or bill raised, a task running behind on the Gantt — is the trigger.

Project Event Happens
A task is assigned or falls due, a milestone is reached, a project PR or bill is raised, or a task runs behind on the Gantt
Alert Rule Matches
The event maps to a recipient and a channel — assigned user, owner, customer, manager or accounts, by WhatsApp, email, SMS or a combination
Message Delivered
The alert goes out with the project, the task and the expected action — enough to act on without logging in first
Action Lands on the Task
The owner updates progress, the approval is granted, the bill is passed — and the task log, Gantt and dashboards reflect it immediately
The alert families

Six alerts that keep every task,
milestone and approval on time

Every alert is tied to a real task in the WBS — so the notification, the action and the task log always agree.

Task assigned Assigned user
Task-assignment reminders
When a WBS task is assigned to a user, that person is notified with the task, its dates and its priority — so a new task never sits unseen at the bottom of a screen no one opens.
Fires on task assignment
Task, project and dates named
Priority carried in the message
Assigned user knows on day one
Due date Task owner
Due-date reminders
The task's finish date drives a reminder to the owner before it falls due, and a nudge on the day. The task gets attention while there is still time to hit the date, not after the Gantt bar turns red.
Driven by the task finish date
Fires before due, not after
Owner and progress % shown
Keeps predecessors on schedule
Milestone reached Owner + customer
Milestone & approval alerts
When a project stage is completed or a step needs sign-off, the project owner and customer are told — so a milestone handover or an approval decision does not wait on someone opening the project view.
Fires when a milestone completes
Owner and customer kept in the loop
Approval requests routed to the right person
Ties into milestone billing
PR raised Manager
Project-PR approval alerts
When a task raises a project purchase requisition for a shortfall, the manager and purchase team are alerted to approve — so procurement for the project moves the day it is needed, feeding inventory & procurement.
Fires on a pending project PR
Task, item and quantity named
Routed to the approver
No task waits on a stalled PR
Bill raised Accounts
Bill approval alerts
Project, RA/progress and subcontractor bills waiting on sign-off alert accounts and the manager — so a bill to raise or a supplier bill to pass does not sit in a queue and hold up cash flow on the project.
Covers project, RA and subcontractor bills
Bill, project and amount named
Routed to the approver in accounts
Task behind Project manager
Schedule-slippage warnings
When a task passes its finish date without completing, or a silent task blocks its successors, the project manager gets the warning — with the task and how far behind — so the Gantt is corrected before slippage spreads.
Fires when a task runs behind
Task and days-behind stated
Flags blocked predecessors
Progress-update prompts chase silent tasks
01 — Task & Due-Date Reminders

The owner acts the moment
the reminder lands

A task assigned to someone who never opens the project view is just a bar that will turn red. When a task is assigned in the WBS and again as its finish date approaches, the notification reaches the assigned user and owner with everything needed to move: which project, which task, which dates, how urgent. The due date and the owner's awareness start together.

Instant reminder on assignment — no waiting for a review
Full context: project, task, dates, priority
WhatsApp for the thread, SMS for the field — or both

02 — Reminders & the Alert Ladder

Remind before it's due.
Escalate only when it slips

Good alerting has a ladder. The assignment and due-date reminder give the owner the chance to finish the task before its bar slips. If it goes silent, a progress-update prompt chases it. If it passes its date, the slippage warning reaches the project manager. And a milestone, PR or bill routes straight to the person who signs it off. Each rung is tied to a real project event — so people act on exceptions, not on a printed pending list.

Assignment and due reminders fire before the date
Slippage warnings fire when a task runs behind
Task and action named — accountability, not noise
The Gantt and task log stay the source of truth

03 — PR, Bill & Slippage Alerts

The project never waits
on a stalled approval

Most teams find out a project PR is stuck when a task stops for material, that a bill was never passed when the cash doesn't arrive, and that a task slipped at the monthly review. Fast Project alerts on every pending project PR, on project, RA and subcontractor bills awaiting sign-off, and on tasks running behind on the Gantt — so procurement moves, cash flows, and slippage is caught early. The alerts feed the same billing & accounts flow your project already runs.

Everything WhatsApp, email & SMS alerts cover

Task-Assignment Reminders

A WBS task assigned to a user notifies that person with the task, its dates and priority — so no task sits unseen at the bottom of a screen no one opens.

Due-Date Reminders

The task finish date drives a reminder to the owner before it falls due, and a nudge on the day — so tasks are hit on time, not discovered overdue at month-end.

Milestone & Approval Alerts

Project owner and customer are told when a stage is reached or a step needs sign-off — so handovers and approval decisions do not wait on someone opening the project.

Project-PR Approvals

A task raising a project purchase requisition alerts the manager and purchase team to approve, so procurement moves the day the task needs the material.

Bill Approvals

Project, RA/progress and subcontractor bills awaiting sign-off alert accounts and the manager — so cash flow on the project is not held up in a queue.

Progress Prompts & Slippage

Silent tasks get a progress-update prompt and tasks running behind warn the project manager — and every alert feeds Dhruv AI analytics, one task record behind every channel.

"We used to find out a task had slipped at the monthly review, and that a subcontractor bill was never passed when the supplier called. Now the site engineer gets the task on WhatsApp the moment it's assigned, and the manager gets the slippage warning before it spreads down the Gantt — the project moves without anyone chasing a report."
