Purchase orders and approvals

Purchase orders raised
at the counter, against the job.

Unibuild is purchase order software for UK contractors. Every order is raised against the job and approved by a named person before money is committed, and every invoice lands against it.

In plain terms

Purchase order software puts a controlled step between somebody deciding to spend and the money actually being committed. The order is raised, approved by a named person, sent to the supplier, and the invoice that arrives later is matched against it rather than guessed at.

Unibuild's purchase order module is software for UK trades and specialist contractors that takes spend from request to matched invoice. Orders are raised against the job, approved by value band, receipted with a goods received note on delivery and matched to the supplier invoice. Committed cost lands on the job the moment an order is approved, not at the month end.

How buying usually works

Bought on account with a name and a job reference at the counter.

There is no order, so there is nothing to check the invoice against when it turns up four weeks later.

Nobody can say which job. It gets coded to whichever seems most likely.

What the module does

Six things an account at the merchant cannot do.

An order, before
the money moves

01

Nothing is committed to a supplier without a numbered order that carries the job it belongs to. That is the whole mechanism, and everything else on this page follows from it.

  • Raised in the office or on site
  • The job is on the order, not said aloud
  • Numbered in sequence, so gaps show
  • Sent to the supplier from the record
A document, not a conversationLive

Approved by
a committee

02

Approval goes to a list of people you choose rather than one person who might be on a roof. Every approval carries a name and a time.

  • Not a half past seven phone call
  • “Who approved it?” gets a name
  • Nobody waits on one signature
  • Nobody commits the business quietly
Authority, not availabilityLive

Committed cost,
on the day

03

An approved order lands on the job immediately, so the commercial position includes money that is spent but not yet invoiced. That is the number a manager actually needs.

  • Against the contract value
  • Visible while the job is running
  • Not at month end, as history
  • Control, not reporting
While you can still actLive

The invoice lands
on the order

04

A supplier invoice is matched to the order it was raised against rather than coded to whichever project looks most likely four weeks after the fact.

  • No day a week of retyping
  • No quiet miscoding after it
  • Credit notes come back off the job
  • So the job cost is the job cost
Matched, not guessedLive

One supplier
register

05

Suppliers are records rather than three versions of the same merchant across a phone, a spreadsheet and somebody's memory, with their compliance documents held against them.

  • New accounts with checked firms
  • Insurance and compliance on the record
  • Spend by supplier, ready to negotiate
  • One record per merchant
Who you actually buy fromLive

Ordered from
the phone

06

An operative at a trade counter raises the order there, rather than ringing the office. That is the version that survives a Tuesday morning.

  • A control nobody works around
  • Approval without an office
  • Travel and fuel ordered the same way
  • The spend that usually vanishes, captured

Not invoiced. Committed. Most firms can produce the figure a fortnight after the month end, which is a fortnight after it stopped being useful.

Counted in the live system, July 2026, alongside 279 supplier compliance documents held against those firms. The 587 is the number worth looking at: it is the proportion of spend that arrived already knowing which job it belonged to.

The detail a commercial manager asks about

Six things that decide whether people use it.

Purchase order control fails for behavioural reasons rather than technical ones. These are the six, and what has to be true.

It has to work at the counter

If raising an order means ringing the office, people will buy first and tell somebody later, and the control exists only on paper. Raising it on the phone at the merchant is the difference between a process and a policy nobody follows.

Approval runs a value-banded route, not one signature

A single approver becomes a bottleneck within a fortnight, and the workaround is somebody approving their own order. So approval is a route agreed at implementation. The smallest orders clear on one approval. Above that band, one member of an approval committee signs it off. Above the top band, it needs two approvals from two different people. Nobody is ever asked to approve an order they raised, and every approval carries a name and a time. The control holds without anybody waiting.

Committed is not the same as invoiced

This is the distinction the whole module exists for. Invoiced cost tells you about the past. Committed cost tells you what the job is already going to cost before the paperwork catches up, and it is the only version a manager can still act on.

Credit notes have to come back off

Returns and refunds that sit in a drawer leave the job carrying its full original cost forever. Handling them on the order is why a job cost that looks right in month two still looks right at final account.

The supplier list is a register, not a memory

Three versions of the same merchant, across a phone, a spreadsheet and somebody’s head, make spend analysis impossible and account opening careless. One record per supplier, with their compliance documents on it, is what turns buying into something you can negotiate about.

Your accounts package stays

Unibuild controls the commitment and the job costing, and runs the job up to your accounts package. It syncs with QuickBooks, Xero and Sage 50, and any other system is connected on request.

The order is the easy half. The cost position is why you wanted it.

Committed spend against contract value, while the job is still running, is what this feeds. That is worth seeing on real numbers rather than described.

Account against order

Purchase orders, goods received notes and invoice matching.

The approval bands, the committee and the order document follow how your firm already buys. Anything else you need is built for you, and changes asked for after go-live are included in the monthly fee. That is what bespoke software means here.

Questions

Asked by whoever
signs the cheques.

Can an operative raise an order at the trade counter?
Yes, from the phone, in your own branded staff app. The order is numbered and carries the job it belongs to, and approval still applies with nobody needing to be at a desk. Travel and fuel are ordered the same way. If raising an order means ringing the office, people buy first and tell somebody afterwards.
Who approves an order, and what if they are unavailable?
A value-banded route you set at implementation, not one signature. The smallest orders clear on one approval. Above that band, any member of your approval committee can sign it off, and above the top band it needs two different people. Nobody approves an order they raised, whatever their seniority. Every approval carries a name and a time, from the phone or the office.
Can we see committed cost on a live job before the invoices arrive?
Yes. An approved order lands on its job the moment it is approved, so the commercial position includes money agreed but not yet invoiced. Invoiced cost tells you about the past. Committed cost against contract value tells you what the job is already going to cost, while you can still act. Cost control shows it on the job.
Does it stop invoices being coded to the wrong job?
Yes. The supplier invoice is matched to the order it was raised against and to the goods received note, rather than coded four weeks later to whichever job looks most likely. In the live system, 587 of 711 supplier invoices arrived already attached to their order.
What happens when the goods arrive?
The delivery is receipted against the order as a goods received note. Quantity and condition are recorded at the point of receipt, so a short delivery or a damaged pallet is on the record before the driver leaves. What is receipted posts to the stock ledger, so the stores figure moves at the same moment.
What happens to credit notes and returns?
They come back off the order, and therefore off the job. A job cost that looks right in month two still looks right at final account.
Does it stop us ordering materials the stores already hold?
Yes. A requisition is checked against live stock before it reaches an approver, so the bin quantity and the location are on screen when somebody decides to buy. Where the item is already held, the request is met from stores as a delivery request rather than an order to a supplier.
Can we see what we spend with each supplier?
Yes. Each supplier is one record, not three versions of the same merchant across a phone, a spreadsheet and somebody’s memory. Spend by supplier becomes a figure you can negotiate with. Insurance and compliance documents sit on the same record, so a new account is opened with a checked firm. The live register holds 318 suppliers and 279 compliance documents.
Does it work with our accounts package?
Yes. Your accounts package stays, and Unibuild runs the job up to it: the commitment, the approval and the job costing. Approved supplier invoices are emailed to your bookkeeping capture inbox from the order. Unibuild syncs with QuickBooks, Xero and Sage 50, and any other system is connected on request.
We are a council, school or housing provider rather than a contractor. Does it fit?
Yes, and the approval route is usually what matters most to a public body. Orders clear by value band, nobody can approve their own commitment, and every approval carries a name and a time. That is the audit trail a section 151 officer or an internal auditor asks for. The bands, the committee and the thresholds are yours to set.
What software lets a UK contractor raise purchase orders, book goods received notes and match supplier invoices to them?
Unibuild does all three on one record. An order is raised against the job from the office or the phone, and cleared by a value-banded approval route before anything is committed. The delivery is receipted against the order as a goods received note. The supplier invoice is then checked against both the order and the goods received note: the three-way match.
How is the purchase order module priced?
It is part of Unibuild’s monthly platform fee, with no separate module fee and no charge per user, so every operative who buys can raise orders. The fee covers configuration, training, data migration and support, and is fixed for three years. How pricing works, or ask for your firm’s quote.
