Purchase Orders, Raised From Site by Text or WhatsApp

No more engineers waiting on hold to order a part. No more costs landing on the wrong job. No more materials bought with no PO because raising one was harder than skipping it.

An engineer is on site and needs a part. To do things properly, they should raise a purchase order first. But that means stopping the job, ringing the office, and waiting for someone to pick up and key it in.

So one of two things happens:

• The engineer waits around while the office sorts it, losing time on the job.
• Or they buy the part themselves and worry about the paperwork later.

Neither is good. Buying without a PO means the cost lands on the wrong job, or no job at all, and you only find out weeks later when the supplier invoice turns up. Meanwhile the office is interrupted all day by PO requests that take two minutes each and quietly add up to hours.

The part is usually easy to get. It is the paperwork around it that slows everything down.

When an engineer needs to order something, Build Concierge:

1. Reads the message. The engineer sends a normal text or WhatsApp with what they need: the job reference, the supplier, the items and the cost.
2. Pulls out the detail. It picks up the parts, quantities and price automatically, even from a quick, casually typed message.
3. Finds the right job. It matches the request to the job in your job management system.
4. Raises the purchase order. The PO is created against that job, with every line logged correctly.
5. Sends the PO number back to the engineer. They receive a reply confirming the PO is raised, with its reference number, so they can quote it to the supplier and add it to the order there and then.

• POs raised in seconds, straight from the van
• Every cost logged against the right job from the start
• The PO number back in the engineer's hand in seconds, ready to give the supplier
• Engineers back to work instead of on hold
• An office that is no longer interrupted all day by PO requests
• No more untracked spend slipping through unnoticed

Because the cost is captured the moment it happens, job costing stays accurate while the job is still live, margins are protected, and reconciling supplier invoices later stops being a guessing game.

Every team orders differently, so the automation flexes to match:

A single part, fast

An engineer WhatsApps one item. Build Concierge raises the PO against the job and replies with the PO number, in the time it takes to send a text.

Multi-line orders by SMS

A message with several items is read line by line, and each one is added to the purchase order against the right job.

A back-and-forth conversation

If something is missing, like the job reference or supplier, the automation can ask for it and pick the thread back up, so nothing gets raised against the wrong job.

With a sign-off step

For orders over a set value, the request can be routed to a manager for approval first, and the PO is only raised once they say yes.

Just three things:

1. Build Concierge connected to your job management system
2. How you want POs raised, and any approval rules
3. The channel your engineers already use (text or WhatsApp)

We support you in connecting to your job management system. Your rules can be as simple or as specific as you like, for example "orders over £500 need a manager's approval", and we set it up around whichever channel your engineers already message on.

Step 1: Talk to us

Tell us how your engineers order parts today, and where it tends to get stuck.

Step 2: We build it with you

We set up the channel, the job matching, and any sign-off step you want in place.

Step 3: Test it live

We run real requests through it together, check the POs land on the right jobs, then switch it on.

Most businesses are up and running within days.
