From the site's material request to a purchase order the supplier can trust
The site asks for material in BuildAura instead of on a call. You approve or reject each line, the purchase team turns approved lines into a purchase order, and the store receives against it. Nobody can quietly receive more than was ordered.

How a purchase moves
- 1
Request
The site or the warehouse raises a material request from the app.
- 2
Approve
Each line is approved or rejected. The requester is notified either way.
- 3
Order
Approved lines go into a purchase order and are marked ordered.
- 4
Receive
The store records what actually arrived against the order.
- 5
Bill and pay
The bill is booked from the goods received, and payments are recorded against it.
One purchase, followed from the site to the payment
Because the request, order, receipt, bill and payment are linked, anyone with access can see where a purchase stands and what is still open.

Who uses it
- Site engineer
- Raises material requests from the site and sees when they are decided.
- Owner or approver
- Approves or rejects each requested line and each purchase order.
- Purchase team
- Turns approved lines into orders and follows deliveries.
- Store keeper

Good to know
- The purchase order goes out from your own WhatsApp or email, so the supplier sees it come from you. On a computer without file sharing, Share on WhatsApp downloads the PDF and opens WhatsApp with the PO number written, ready for you to attach it.
Common questions
Can the site raise a request from a phone?
Yes. BuildAura installs on Android and iPhone from a link, and material requests are raised from the same app the site uses for attendance and tasks.
What happens when the supplier sends less than we ordered?
Record what arrived. The order shows as partially received with the balance open. If the rest will never come, close it short with a reason.
Can we stop people approving their own requests?
Approval of material requests is a separate permission. By default only the owner has it, and you decide who else gets it.
Can I send the purchase order to the supplier on WhatsApp?
Yes. Open the order, tap Share and choose Share on WhatsApp or Send Email. BuildAura makes the PO PDF, with your logo, GST split, terms and signature, and on a phone attaches it for you. On WhatsApp it is captioned with the PO number and the supplier's name; by email it comes with a short covering note asking for the invoice after delivery.
