Your purchases can't stay on WhatsApp: gain margin and control in your restaurant today
From crumpled invoices to real-time control. This is how margin is cooked in 2025.
Clara passionately runs two honest cuisine establishments in a medium-sized city. She has a team of twelve people, three storage rooms, and a list of six trusted suppliers, plus another four that come and go. But here comes the problem: all her orders are placed via WhatsApp. Invoices arrive disorganized, by email, on paper, and sometimes even in a cardboard box on Mondays. Clara is excellent at selling; however, when it's time to close the till… she's not clear how much she's earned or why.
One Sunday night, at 11:15 PM, reviewing receipts, she had a revelation: it's not the kitchen that's failing. The problem lies in the system. The digitalization of purchasing is not a passing trend; it's her new strategy for sleeping soundly.
Old way vs new way: the game is won in the back of house
Before: orders via WhatsApp, price changes without notice, lost invoices. Now: centralized orders in Guava (guavapp.com), catalog and agreed prices visible to all.
Before: counting stock by hand, struggling with Excel, and asking "whose delivery note is this?". Now: OCR technology that reads invoices in seconds, accounts payable automation, and price difference alerts.
Before: annoying suppliers, annoying you. Now: clear communication, approval rules, and well-defined deadlines. Suppliers are managed professionally.
Three simple moves to digitize your purchasing
Centralize purchasing and set the catalog Clara started with the essentials. Now she has a single dashboard where she can see who orders, what, and at what price. Say goodbye to "just give me the usual." With Guava, the TPV and purchasing software work together, showing real sales, consumption, restocking recommendations, and negotiated prices. Result: she only buys what really moves. She no longer overpays for impulse buys.
Automate accounts payable with OCR Invoices arrive however they do, perfect. Let the system take care of organizing them. With OCR invoice processing in Guava, it captures key data, cross-references information with orders and delivery notes, flags errors, and prepares accounting entries. All that's left for you is to approve. No typing. No chasing papers. Reducing errors is not a luxury; it's what ensures a healthy cash flow.
Rules, budgets, and real-time visibility Clara set limits by category: fish, meats, cellar. The software does not allow orders that exceed the budget or prices outside of agreement. Need to make an exception? Just two clicks and everything is recorded. Having visibility of projected cash flow and future obligations avoids unpleasant surprises at the end of the month. Mandate: there will be no purchase without data.
Does this sound familiar?
- Weeks with good sales but low margin.
- Suppliers who change formats and the cost per serving skyrockets.
- Shifts that buy "just in case" and then waste accumulates.
The digitalization of purchasing in hospitality is not an IT project. It's an opportunity to recover those 2-3 points of operating margin that are now slipping away between vacuum bags and vegetable boxes. It's time. It's judgment. It's building long-term relationships with your suppliers, based on data and trust, instead of urgencies.
How Clara started to notice it (and you will too)
- Shorter and more accurate inventories, thanks to Guava's TPV connecting sales with consumption.
- Prices under control: if a price goes up, you receive an alert. You can negotiate with solid arguments.
- Aligned team: only 30 minutes of training, clear roles, and less friction.
- Faster daily closings: the dashboard tells you what to approve and what is pending.
I don't promise you magic. I promise you a method. If you sell well but don't see the money, the problem isn't in the front of house, but in purchasing.
