How to Negotiate Prices With Your Restaurant's Suppliers (With Real Data)

There's a conversation every restaurant owner needs to have with their suppliers, and most keep putting it off. Not for lack of willingness, but for lack of arguments. When you don't know exactly how much you spend, when prices went up, or on which items, it's hard to walk into that conversation with confidence. This article explains what you need to prepare, and how to show up with solid data in hand.

Your suppliers have updated their prices. Do you know by how much?

Fish got more expensive. So did olive oil. Your meat supplier came by last week and said "costs went up." You nodded, signed the delivery note, and life went on.

The problem isn't that prices go up. Prices rise, that's certain and it will keep happening. The problem is not knowing exactly how much they went up, on which items, since when, and whether what you're paying is in line with the market or whether there's room to negotiate.

Without those numbers, you don't have a conversation. You have a feeling.

Negotiating without data is asking for a favor

Most restaurant owners negotiate like this: they sit down with the supplier, say costs are high, ask for a discount, and wait. The supplier replies that they have costs too, that raw materials went up, that they're doing what they can. And the conversation goes nowhere.

Not necessarily because the supplier is right. But because you showed up empty-handed.

When you bring data, the dynamic changes completely. Instead of "prices are high," you can say: "Over the last six months I've spent €4,200 with you. The price of shrimp went up 22% between October and March, while the volume I buy from you stayed steady. I want to understand what we can do about it." That's a different kind of conversation, and your supplier knows it.

What you need to know before sitting down at the table

Before any supplier negotiation, pull together these numbers for the supplier in question:

• Total amount paid over the last 3 to 6 months
• Price trend per item: what you used to pay and what you pay now
• Items with the biggest change: where the increase was steepest and most recent
• Purchase frequency: buying every week is worth more than one large occasional order

With this data, you know where you have leverage. Volume and regularity are bargaining chips. Documented price changes are facts, not opinions, and it's much harder to ignore a fact than a feeling.

It's also worth figuring out whether you have a real alternative. A supplier knows when you're the kind of customer they can lose without consequences. Having a backup option, even if you have no intention of switching, shifts the balance of the conversation. If you have that option, there's no need to hide it.

How to run the negotiation with data in hand

You don't need to be aggressive. The goal isn't to create conflict, it's to create a fact-based conversation where both sides come out ahead in some way.

Start by acknowledging the relationship: how long you've worked together, what's gone well. That's not weakness. It's positioning, and it frames you as a partner, not an opponent.

Then present the data. Show the price trend, the volume you represent, and the concrete impact on your business. You don't need to exaggerate. Numbers speak for themselves when they're specific and verifiable.

Finally, make a concrete proposal. "I can keep this monthly volume if we can stabilize the price of shrimp for the next quarter" is very different from "I need a discount." Concrete proposals get concrete answers. Vague requests get vague answers.

When negotiating makes the most sense

A common mistake is negotiating only when cash gets tight. Under pressure, your bargaining power drops, and the supplier can tell. There are better moments to have this conversation:

• After a period of high volume: spring, summer, holidays. You've just proven you can guarantee regular orders.
• When a price jumps sharply: don't wait months. React while the data is fresh and the increase is recent.
• When you're considering adding a new item to the menu: you have extra leverage to negotiate the main ingredient.
• Annually, even when everything is fine: regular negotiations build a more balanced relationship and prevent unpleasant surprises.

The idea is to turn negotiation into a regular practice, not an emergency reaction.

How Tinz prepares your negotiation arguments for you

Gathering this data by hand is a lot of work. You have to open invoices, compare dates, calculate averages per item, supplier by supplier. It's the kind of task that always gets pushed to next week.

In Tinz, every invoice you upload automatically feeds your purchase history. In the Entities section, you see the complete profile of each supplier: total spent, products purchased, and automatic alerts when an item's price rises above its historical average. In other words, you know about a price increase before you feel it in your margin.

In the Analysis section, the Items tab shows the price trend of every product over time and flags the ones with the biggest changes between purchases. In two minutes you have the history you need to walk into any conversation with solid arguments.

And in the Operations section, on the Orders tab, the Prepare negotiation button automatically generates the arguments for each supplier based on your real history: volume purchased, price changes, and trends from recent weeks.
