Send us what you have
PDFs, ERP exports, portal downloads, spreadsheets. API connectors are available for most ERPs.
Know what you buy, from whom, at what price.
Your invoice data is full of answers. Pearstop makes them usable. Your data doesn’t need to be cleaned first. That’s the work we do.
Trusted by leading organisations
See it work on your own data
Send a representative sample of your invoice lines – up to 200 lines, or a handful of invoices (max 10) – and we'll classify them and send them back labelled. No cost, no setup, nothing to install. It's the fastest way to see exactly what Pearstop does before you commit to anything.
“Most companies are flying blind, and only find out when someone asks a question they cannot answer.”

Stage 2
We clean, enrich, and classify every line
We extract everything we can find on the line, fill in what’s missing using supplier and purchasing history, and classify it to UNSPSC – down to the granularity that actually answers your questions, not just a top-level category.

Stage 3
Your spend stays classified
As new invoices arrive, they're classified the same way - no re-cleaning project every year.

Illustrative example: six invoice lines from three suppliers. The original description and supplier are kept exactly as they arrived – Pearstop only adds the columns on the right.
* Category inferred from additional data (purchase history and contract context), not stated directly on the invoice — flagged at medium confidence rather than high.
Who it's for
Facilities Management
Your data arrives from every service line in a different format.
See how it applies →Construction
You're estimating bids from memory because nobody can retrieve historical actuals.
See how it applies →Infrastructure
A savings target has been named and the data can't show where it sits.
See how it applies →Manufacturing
One entity already runs UNSPSC and another needs to align to it.
See how it applies →“Our data isn’t clean enough for this.”
That's the most common thing we hear – and it's the reason to start now rather than wait. Cleaning the data is the first thing Pearstop does, not a prerequisite for working with us.
“Won’t it be cheaper to build this ourselves?”
In-house gives you complete control, but expect to dedicate two data or AI specialists to build it properly and keep maintaining it as your data changes. We've seen an internal build start as an IT team's side project, ship without procurement involved, and turn into a spreadsheet nobody owns within months. Pearstop is that system already built – with a team whose only job is to keep developing it.
Cases
Infrastructure Contractor
A named savings target. The data couldn't locate it. Pearstop made it visible.
“We used to have two full-time staff working on category assignment. Now the system does this for us – which has unlocked margin estimations further down the line too. It's more reliable at a fraction of the cost.”Head of Procurement, Infrastructure
Read the case →Facilities Management Provider
100,000+ assets cleaned and resolved. 93% automated. The remaining 7% routed to domain experts.
“Our asset lists worked for mechanics on-site, but did not allow us to plan smart maintenance or manage bid risk in a data-driven way.”Asset Manager, Facilities Management
Read the case →Cleaning Services Company
Extraction accuracy: 70% → 99%. Moved from manual review to an ongoing subscription.
“It would have taken five engineers and a full year to clean this up. So we decided to look for a better solution.”Head of Operations, Cleaning Services
Read the case →Send us 200 lines. We will send them back labelled.
Frequently asked questions
What is UNSPSC classification?
UNSPSC is a global standard for categorising products and services into a consistent hierarchy. It lets you compare spend across suppliers, sites, and time periods using the same categories, instead of whatever free-text description each invoice happened to use.
How do you classify spend data that isn't clean?
Your data doesn't need to be clean first - that's the work we do. We take invoices, ERP exports, portal downloads, or spreadsheets in whatever state they're in, and extract and classify every line automatically.
Can you extract data from PDF invoices?
Yes. Pearstop reads PDF invoices, scanned documents, and portal exports directly, so you don't need a clean digital export to get started.
How accurate is automated spend classification?
Around 95% of lines are classified automatically. The rest are flagged and routed to a human reviewer, so accuracy stays high without every line needing manual checking.
How long does spend classification take?
A first sample of 200 lines is typically turned around within a few working days. Ongoing classification runs continuously as new invoices arrive.
What does Pearstop do?
Pearstop helps facilities management, infrastructure, and hard services companies clean procurement and asset data so teams can see what they are buying, plan maintenance more reliably, and feed trustworthy data into AI and reporting tools. If you need one plain answer, it is this: we turn messy operational data into something your business can actually use.
