A document moves.
The right person hears it
on WhatsApp.

Fast ERP Software puts WhatsApp on top of the whole business. An order is confirmed and the customer knows. A purchase order needs sign-off and the approver is asked. A goods receipt is booked and purchase is told. An invoice falls due and accounts and the party are reminded — each message triggered by a real ERP document event, not by someone remembering to send it.

Two directions, one document

WhatsApp keeps the business informed
and chases the people who decide

Some messages keep customers, vendors and teams updated; others chase the person who has to approve or pay. Fast ERP Software uses WhatsApp for both — everyone knows where an order, purchase order or invoice stands, and approvers and accounts are nudged before a delay becomes a problem.

Keeping everyone informed
Status the business receives
From a confirmed order to a booked goods receipt to a dispatch on its way, the right people hear what changed. Sales and customers get order and dispatch updates, purchase and stores get PO and GRN notices — no one has to phone around for status.

Actions the team receives
A purchase requisition, purchase order or expense waiting for sign-off, an invoice or supplier bill nearing its due date — the request goes to the approver or to accounts with the document, amount and party named, so it's actioned, not stuck in a queue.

How it works

From an ERP event to the
right message, in the right hand

WhatsApp is the channel. The order, purchase order, goods receipt, invoice or voucher is the system of record. Fast ERP Software keeps the two in step from enquiry to payment.

An Event Fires
An order or PO changes status, a goods receipt is booked, a document is sent for approval, or an invoice nears its due date
The Right Person Is Chosen
The message is routed by document and role — approver, sales, purchase, accounts or the party contact — not blasted to everyone
WhatsApp Delivers It
A plain-language message with the document number, amount and party goes out on WhatsApp — no screen to check first
It's Logged on the Document
Every message is recorded against the document, so the ERP record shows what was sent and when
Every touchpoint

Six WhatsApp moments that keep the business
moving — without anyone remembering to send them

Each message is triggered by a real event on an ERP document — an order or PO status change, a goods receipt, a dispatch, an approval routing, a due date reached. Nothing depends on a person remembering to type an update.

Order Customer
Order status updates
As a sales order moves — confirmed, in production, ready to dispatch — sales and the customer contact are told, so no one has to chase for where the order stands.

PO status updates
When a purchase order is approved, sent to the vendor or its delivery slips, purchase and the supplier get an update — so follow-up happens before the material is late.

Approval requests

01 — Order & PO Status Updates

The customer and the vendor know
where it stands — without a call

An order and a purchase order don't sit still: they're confirmed, they move into production or delivery, they close. Each status change on the sales order or the purchase order maps to a WhatsApp update, so sales, purchase and the party know the document moved — the item, the quantity and where it is now — without anyone phoning around.

02 — GRN, Dispatch & Approvals

The approver is asked
before the queue builds

The slowest step in most orders is the one waiting for a sign-off. When a purchase requisition, purchase order or expense is routed for approval, the approver is asked on WhatsApp; when a goods receipt or dispatch is booked, stores, purchase and the party are told. Each message names the document, the amount or quantity and the party — the procure-to-pay flow keeps moving.

03 — Payment & Due-Date Alerts

The due date gets chased
the day it matters

An invoice nearing its due date and a supplier bill about to fall payable are the moments that decide your cash flow — and they're the ones most easily missed on a busy ledger. WhatsApp reminders push them to accounts and the party with the document and amount named, so the receivable is chased and the payable scheduled on time, not after it slips.

Everything WhatsApp automation covers

Order & PO Status Updates

Confirmed, in progress, dispatched, received — each order and purchase-order status change sends a plain-language update with the item, quantity and party.

GRN & Dispatch Notices

A goods receipt booked against a PO, or a dispatch raised against an order, notifies stores, purchase and the party with the quantity in or out.

Approval Requests

A purchase requisition, purchase order or expense routed for sign-off asks the approver on WhatsApp with the document, amount and party.

Payment & Due-Date Alerts

An invoice or supplier bill nearing its due date reminds accounts and the party with the document and amount — receivables chased, payables on time.

Payment Confirmations

A payment released or a receipt recorded confirms accounts and management with the party, amount and reference, so cash position stays clear.

Works With Every Channel

WhatsApp complements the Tally posting and email/SMS alerts — the ERP document is the single record behind every channel.

"Approvals used to sit for a day before anyone even saw them. Now the approver gets the WhatsApp the moment a purchase order is routed — the sign-off happens from the phone before the vendor even follows up."
