Procurement software for UK SMEs

Win better supplier prices, without a procurement team.

Purchasing Portal turns your supplier invoices into competitive tenders, gets suppliers bidding against each other, and checks every invoice afterwards so you never quietly drift back to overpaying.

The quiet cost

Most SMEs overpay, simply because nobody has the time to check.

Running a proper tender takes days of gathering invoices, chasing quotes and comparing apples with pears. So prices go un-tested for years, and suppliers know it.

Days

Lost to invoice admin

Pulling together a year of supplier spend by hand is the most time-consuming part of any tender. It is why most never happen.

Apples

Compared with pears

One supplier quotes per case, another per unit, a third per pallet. Without normalising it, you cannot see who is actually cheapest.

Drift

Back to overpaying

Even after a good deal, prices creep up invoice by invoice. Without monitoring, the saving you fought for quietly disappears.

How it works

Four steps from spend to savings.

The AI does the heavy lifting at every stage. You stay in control, with a human review step before anything goes to suppliers.

Connect or upload

Link Xero or QuickBooks, or drop in PDFs, spreadsheets and CSVs. The AI reads every invoice and builds an accurate picture of what you buy and what you pay.

Launch a tender

Purchasing Portal drafts the request for quote from your real spend. Invite suppliers, who quote on a clean, validated form. No messy spreadsheets.

Let them compete

Run an optional reverse auction. Compare every quote normalised to a true cost per unit, then get a plain-English AI recommendation on where to push.

Lock it in, stay protected

Agree your prices. From then on, every future invoice is checked automatically against what was agreed, and any overcharge is flagged.

The product

Your spend, finally legible.

Every invoice read, every product matched across suppliers, every line ranked by spend. This is the picture Purchasing Portal builds for you, automatically, ready to take to tender.

A complete procurement toolkit built for businesses without a buying department.

Find the savingsTurn messy invoices into a clear spend picture

AI spend analysis

Upload any volume of invoices. The AI extracts products, quantities and prices, then aggregates total spend per product and per supplier.

AI-built tenders

Drop in a quote sheet, invoice or purchase order in any format. Purchasing Portal reads it and pre-populates your tender, flagging anything to review.

Accounting integration

Connect Xero and QuickBooks Online to pull purchase invoices automatically, including the attached PDFs. Read-only, never written back.

Xero live first
Run the tenderGet suppliers competing on a level field

Supplier management

Keep your supplier database in one place with categories and history. Assign suppliers to each tender with a unique link, no login required.

Clean quote submission

Suppliers quote on a structured form with pack size, lead time and minimum order built in. Every quote comes back comparable, with no free-text mess.

Reverse auctions

Run a live, time-limited bidding event. Suppliers see the lowest price anonymously and bid lower, with overtime rules to keep it competitive.

Quote comparison

An automatic side-by-side table, normalised to true cost per unit, with the incumbent price as your baseline and the saving calculated per line.

AI recommendation memo

One click produces a professional, board-ready memo: best value overall, where the incumbent is still competitive, and clear negotiation guidance.

Anomaly detection

The system flags prices that look unusually high or low, pack sizes that do not match spec, and missing fields, before they cost you.

Protect the resultKeep the savings you worked for

Price compliance monitoring

Every purchase invoice is matched against your agreed price automatically. Overcharges are flagged to you with the exact amount and supplier.

Savings tracking

A live dashboard of total saved, by category and supplier, with downloadable reports you can take straight into a board meeting.

Price increase management

When a supplier asks for an increase, see the impact instantly. Approve, counter or reject, with the saving you locked in fully preserved.

Agreement generation

Post-tender, the system pre-fills your supply agreement from the results and sends it for e-signature. Signed copies stored against the client.

On the roadmap
The bit competitors miss

A good price is only good if it lasts.

Most procurement tools stop at the tender. Purchasing Portal keeps watching. Every invoice that arrives is checked against the price you agreed, so the moment a supplier slips a rise through, you know.

  • Automatic invoice-by-invoice checking
  • Overcharges flagged with the cash amount
  • Raise a dispute straight from the portal
Two ways to work

Run it yourself, or let us run it for you.

Whichever you choose, the goal is the same: pay less, and keep paying less.

Why Purchasing Portal

Enterprise procurement power, sized for an SME.

The big platforms cost thousands a month and assume you have a procurement department. We do not.

AI-native, not bolted on

Upload an invoice in any layout and it just works. No rigid templates, no manual re-keying, no setup project.

Compliance built in

The ongoing invoice checking that protects your savings is core, not a costly add-on most rivals do not offer at all.

Built for the UK

GBP throughout, UK GDPR, UK court jurisdiction and Xero-first integration. Made for how UK SMEs actually trade.

Honest, simple pricing

From £99 a month for software, or pay from savings on concierge. No five-figure platform fees, no lock-in.

Questions

Good to know.

How much can I really save?
It depends on the category and how recently your prices were last tested, but tenders on previously un-tendered spend commonly return a high single-digit to low double-digit percentage saving. The estimator at the top of the page gives an illustrative figure for your spend, and a demo will give you a far more accurate view once we have seen your real invoices.
Do I need to know about procurement?
Not at all. Purchasing Portal is built for owner-managers, finance and operations people without a dedicated buyer. The AI drafts the tenders, compares the quotes on a true like-for-like basis and writes the recommendation. If you would rather not touch it, the concierge service runs the whole thing for you.
Which accounting systems do you connect to?
Xero first, then QuickBooks Online, with Sage on the roadmap. The platform pulls your purchase invoices and reads the attached PDFs to build an accurate spend picture. You can also upload invoices directly as PDF, Excel or CSV without connecting anything.
Is my data safe?
Yes. Accounting connections are strictly read-only, your data is held in UK and EU regions, and we comply with UK GDPR and the Data Protection Act 2018. We never write anything back to your accounting system.
What does it cost?
Self-serve software starts from £99 per month. The concierge service is a low monthly retainer plus a share of the savings we find, so the bulk of what you pay only ever comes out of money you would not otherwise have saved.
How is this different from the big procurement platforms?
Enterprise tools like the well-known platforms are powerful but expensive and complex, and they assume you have a procurement team to drive them. Purchasing Portal is simpler, far cheaper, AI-native, and includes ongoing price compliance monitoring that most do not. It is designed for SMEs, not multinationals.
