Why manual invoice control fails in most restaurants
The typical workflow in a restaurant without a digital system goes like this: a delivery note arrives with the order, someone signs it and leaves it in a folder, and at the end of the week or month someone — or no one — checks whether the price matches the order. The result is predictable: invoices paid at prices that differ from what was agreed, incorrect quantities accepted without dispute, and an invoice archive that is a pile of paper nobody ever consults. Industry estimates suggest that a mid-sized restaurant overpays on 2–4% of its supplier invoices due to a lack of systematic verification. On €10,000 of monthly purchases, that is between €200 and €400 lost every month without even knowing it.
OCR and delivery note digitisation: the current standard in professional hospitality
OCR technology (optical character recognition) allows you to photograph a delivery note or upload a PDF and automatically extract the data: supplier, date, products, quantities and prices. What used to require 10–15 minutes of manual data entry now takes seconds. But digitising the invoice is only the first step: the real value comes when the system automatically cross-checks that data against the corresponding purchase order and flags any discrepancies. Kitchen Stocker performs this cross-check in real time, so you know before filing the invoice whether you have been charged what was agreed and whether you received what you ordered.
Digital invoice archive: GDPR compliance and access in seconds
Spanish law requires supplier invoices to be kept for four years for tax and commercial purposes. A well-structured digital archive meets that requirement and also allows you to access any invoice in seconds — filtering by supplier, date, amount or product. In the event of a dispute with a supplier or a tax authority review, having a complete, organised and accessible history can make the difference between resolving the matter in minutes or in days. Kitchen Stocker keeps the invoice archive on infrastructure within the European Union, in compliance with GDPR and Spain's LOPDGDD.

Frequently asked questions about restaurant invoice control
Is it legal to archive invoices exclusively in digital format in Spain?+
Yes. Spanish law allows invoices to be archived exclusively in digital format provided their integrity, authenticity and legibility are guaranteed during the mandatory retention period (4 years for most commercial documents, up to 10 for certain tax records). Kitchen Stocker stores invoices on secure servers within the EU in compliance with these requirements.
What happens if a supplier's invoice does not match the order?+
Kitchen Stocker generates an automatic alert when it detects a discrepancy between the recorded invoice and the associated purchase order — whether in price, quantity or product. That alert is logged and you can address it before authorising payment.
Does the OCR work with handwritten or damaged invoices?+
Kitchen Stocker's OCR is optimised for printed delivery notes and standard invoices from Spanish suppliers. For handwritten documents or very poor-quality images, manual review may be needed, although the system pre-fills all fields it can extract automatically.
Can invoices be uploaded as PDFs as well as photos?+
Yes. Kitchen Stocker accepts both photos taken from a mobile phone and PDF files sent by the supplier. Both go through the same OCR extraction engine and are stored in the archive history.
Does Kitchen Stocker's invoice control replace accounting software?+
No. Kitchen Stocker handles the operational side of purchasing and supplier invoices (verification, archiving, cross-checking with orders). For tax accounting you can export the data to CSV for your accountant or accounting software to import.
