Your invoices don't need love; they need OCR

The express guide for hospitality businesses that want to control costs without being glued to Excel.

Lucía is the manager of a small group of restaurants. Her days stretch with never-ending shifts, suppliers who change prices without notice, and a mountain of invoices that looks like a Jenga about to collapse. Sunday, 00:37. Cold coffee. She types figures in the dark because “if I don’t do it today, tomorrow the cash flow will get me.” Sound familiar?

One day, they showed her something that changed her life: there's no need to manually enter invoices. With a simple photo, OCR reads them and the data flies directly to accounting. No drama. No strange sums. And, most importantly, without losing the early payment discount.

What OCR does with your invoices (and why you need it today)

• Converts invoice images into editable data. Be it a photo, PDF, or scan. If the image is clear, the data will be too.
• Automates accounts payable: supplier, date, invoice number, subtotal, VAT, total, line items… everything into the system without complications.
• Reduces errors. Goodbye to those extra zeros and duplicates that drive us crazy!
• Accelerates the cycle: you can process higher volumes without needing to hire more staff. In logistics, reductions of up to 70% in costs and 89% in processing time have been reported thanks to OCR. In hospitality, the results are similar: fewer lost hours and more tables served.
• Get real-time data: make quick decisions about purchases, prices, and margins with updated information.

Electronic invoice vs OCR

• Electronic invoice: born digital and perfectly structured.
• OCR: digitizes what arrives on paper or as simple PDFs.
• Both are complementary. If many of your suppliers still send simple PDFs or paper invoices, OCR is the bridge you need towards automation.

The old way vs the new (a week with Lucía)

Old way:

• Monday: 27 invoices. Two with repeated numbers. One stained. One line with incorrect VAT.
• Tuesday: a supplier calls: “I don’t see your transfer.” The discount deadline was missed.
• Thursday: discrepancies between delivery note and invoice. Again, back to reviewing everything.

New way with Guava (guavapp.com):

• Reception: photo of the delivery note and the invoice. The OCR extracts the data and suggests the supplier.
• Validation: Guava cross-references delivery notes, prices, and planned purchases. If something doesn't match, it notifies you instantly.
• Mobile approval: just two taps. Keep your accounts payable up to date.
• Weekend: receive a cost report by category and dish. Keep your margin under control and close quickly from the TPV and operations panel.

Checklist for implementing OCR in your restaurant

• Define a single channel: create an email “[email protected]” for all suppliers to send documents there.
• Capture standard: ensure photos are flat, well-lit, shadow-free, and show complete documents. Avoid wrinkles! It may seem obvious, but this improves accuracy.
• Appoint responsibles: designate who reviews exceptions (unusual prices, out-of-range VAT, duplicates).
• Activate 2/3-way matching: order — delivery note — invoice. This way you avoid overpaying due to errors.
• Tag by supplier and category: vegetables, meat, beverages. Guava (guavapp.com) centralizes this so you can analyze margins by category.
• Measure ROI: average processing time, error percentage, discounts utilized. If you don't measure it, you can't improve it.
• Educate your suppliers: ask them for legible PDFs and electronic invoices when possible. Less noise, more speed.

Quick tips for fine-tuning OCR

• Avoid tilted photos and textured backgrounds.
• Review 100% of the data in the first 7 days, then you can switch to sampling.
• Define thresholds: if the price increases by more than 5% compared to the last purchase, require approval.
