Invoice processing software for UK finance teams.
Capture every supplier invoice, extract the line-level detail, match it to the purchase order and post it to your ERP. AI reads the invoice. Your team handles the exceptions. It is invoice automation software that runs from the supplier's inbox to a clean record in your finance system.

















Every invoice captured, whatever the format.
Invoices arrive in every shape your suppliers can think of. A PDF by email, a document pulled from a supplier portal, a scanned paper invoice, a structured e-invoice. Stratas captures all of them into one queue.
There are no templates to build for each supplier and none to maintain when a supplier changes their layout. A new supplier works from their first invoice.
Email attachments
Invoices sent straight to your AP inbox are captured automatically, attachment and body alike.
Supplier portals
Documents downloaded from supplier portals join the same queue as everything else.
Scanned paper
Paper invoices that still arrive by post are scanned and read without a per-supplier template.
E-invoices
Structured e-invoices are handled natively, ready for the UK mandate as it lands.
Beyond OCR: extraction that reads like a person.
Invoice OCR software reads characters off a page. That is the easy part. The hard part is understanding what those characters mean: which number is the total, which is the VAT, which lines are the goods you ordered. Template-based OCR needs a fixed layout for every supplier, so it fails the moment an invoice moves a field.
Stratas reads the invoice the way a person does. It finds the header data, the tax breakdown and every line item, whatever the layout, and returns structured data your ERP can use. This is invoice data capture done properly, at 89% extraction accuracy measured on real customer documents. Our data transformation layer, Data Forge, cleans and standardises the output before it reaches your finance system.
Matched, coded and approved automatically.
Captured data is only useful once it is checked. Stratas matches each invoice to its purchase order and goods receipt, line by line, and applies the price and quantity tolerances you set. It codes invoices to the right nominal, department and cost centre using your rules, not a manual keystroke.
Then it routes each invoice for approval to the right person, with the invoice, the PO and any mismatch shown together. Exceptions are flagged for review. Everything that matches cleanly moves on without anyone touching it.
PO and GRN matching
Three-way matching line by line, with the price and quantity tolerances you decide.
Nominal coding
Invoices coded to the right nominal, department and cost centre from your own rules.
Approval routing
Each invoice reaches the right approver with the full context to sign it off or query it.

Common questions.
Invoice processing software captures supplier invoices, extracts the data, checks it against your purchase orders and posts the result to your ERP. Stratas automates each of those steps so your finance team reviews the exceptions rather than keying every invoice by hand.
OCR is one part of it. OCR reads characters off the page, then intelligent document processing works out what they mean, validates the data against your ERP and structures it for posting. Stratas does the full job, which is why we describe it as invoice data capture rather than OCR alone.
PDFs, email attachments, scanned paper invoices, supplier portal downloads and structured e-invoices. There are no per-supplier templates to build or maintain, so a new supplier works from their first invoice.
