How it works

1
Stage 1

Send us what you have

PDFs, ERP exports, portal downloads, spreadsheets. API connectors are available for most ERPs.

2
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.

3
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.

Every line, labelled

The same label on every supplier's line

Each line gets a UNSPSC label as it is read. Toilet tissue from four suppliers ends up in one place, so you can compare it one-to-one.

“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.

The question we get most

We already tried ChatGPT or Copilot on our data - why would this be different?

Because Pearstop isn't a general-purpose AI tool pointed at your data - it's a dedicated pipeline built specifically for procurement and asset data: deterministic matching first, a large language model for the genuinely ambiguous cases, and a human review step for anything still uncertain. Teams who've tried a general AI tool on messy spend data consistently find it works fine in a quick trial and breaks down at real volume. Pearstop is built to hold up at that volume, not just in a demo.

Frequently asked questions

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.

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.
