Negotiating with suppliers is always about the same things: a better price, a longer payment term, a fixed discount. But there's a question that comes before all of that, and almost nobody asks it until it's too late: if this supplier disappeared tomorrow — bankrupt, bought out, or just a customer they'd rather keep than you — how long would it take to replace them, and what would that cost you? Three numbers answer that honestly: how long switching actually takes, how much of your purchasing sits with that one supplier, and what kind of relationship it really is. That last number doesn't come from hospitality — it comes from a field that's been answering exactly this question for forty years: procurement management.

This isn't about negotiating

The seven negotiation tactics published elsewhere on this site assume you already know who you're sitting across from — and that you're in a position to negotiate at all. That's exactly where this article starts: before you negotiate, it's worth knowing how strong your own position actually is, and which suppliers don't allow negotiation at all because there is no alternative. A stock level is the buffer you buy yourself while you look for a replacement — but how much buffer you need depends entirely on how long that search takes. That number is below.

The first number: switching time

Not every supplier is equally easy to replace. A fresh produce or fish supplier that disappears costs a few phone calls and a day bridged by a wholesaler. A specialist importer of something that defines your menu — a specific wine, an olive oil, a spice blend — can take weeks to months to replace, and sometimes means the dish itself has to come off the menu. Switching time is the number that decides how much buffer, and how much panic, a supplier's disappearance actually causes.

Category	Typical switching time	Why
Fresh produce & fish	1–3 days	Plenty of wholesalers cover the same range; quality and price shift, but the door is open
Meat & seafood	3–10 days	Quality and the relationship with the butcher/fishmonger take time to build; a new supplier takes time to trust
Drinks & dry goods	1–2 weeks	A wide field of wholesalers, but contract terms and delivery schedules need re-agreeing
Specialist imports (wine, olive oil, cheese)	4–12 weeks	Often one importer per brand in a country; finding an alternative with the same quality and provenance takes time
Equipment & service contracts	2–6 months	Quotes, installation, warranty transfer, and sometimes a waitlist at the only supplier that services that brand

That spread — days to months — is exactly why "just find another supplier" isn't a strategy that works equally well for every purchasing line. For produce, it's a phone call. For the only importer of your house wine, it's a project.

The second number: spend share

The simplest of the three numbers: what percentage of your total purchasing budget goes to your biggest supplier? No formula, no squaring anything — just the share. That number only becomes meaningful alongside the third number below: a supplier holding 60% of your drinks budget is a completely different situation if it's house wine (easy to replace) versus if it's your only importer of a brand your menu is built around (nearly impossible).

Work it out quickly yourself: pull the last three months of invoices, total them per supplier, and divide by the overall total. Most owners have never actually calculated this number — they only sense "we buy a lot from them" without knowing whether that's 25% or 70%.

The third number: which Kraljic quadrant

In 1983, Peter Kraljic published a model in the Harvard Business Review that has been the basis for how large companies organise purchasing ever since: every supplier — or every product line — gets placed on two axes. Supply risk: how hard is this supplier to replace? And profit impact: how much does this product matter to your menu, your margin, or your identity as a venue? The combination produces four quadrants, and each one calls for a different approach — this is the mistake most independent venues make: applying the same tactic (negotiate hard on price) to every supplier, regardless of which quadrant they actually sit in.

Quadrant	Trait	Approach
Non-critical	Low risk, low impact — office supplies, standard cleaning products	Spend as little time on it as possible; order efficiently, swap without a second thought
Leverage	Low risk, high impact — house wine, standard produce bought at volume	Negotiate hard here: plenty of alternatives, so your market power is real
Bottleneck	High risk, low impact — a specific part for one machine, a niche ingredient for one dish	Don't negotiate, hedge: backup stock, a second contact, or reconsider the dish
Strategic	High risk, high impact — your house-wine importer, your only supplier of the product that defines your venue	Invest in the relationship: a multi-year contract, personal contact, early warning on problems — this isn't a supplier, it's a partner

The most common mistake: treating a bottleneck supplier like a leverage supplier. An owner who negotiates hard on price with the only supplier of a part their only combi oven needs is threatening "I'll buy it elsewhere" against a supplier who knows just as well as they do that there is nowhere else. That conversation is lost before it starts, every time.

Map your own suppliers

Enter up to four suppliers — name, the supply risk they carry and their profit impact — and see which quadrant each one lands in, with the approach that goes with it.

Four quadrants, four different Monday conversations — the bottleneck supplier gets a second contact, the strategic one gets a call to check in on how things are going, and the non-critical one gets no attention at all until the order doesn't show up.

What to actually do with this today

The matrix isn't a report to file away — every quadrant calls for a concrete next step.

Bottleneck: hedge, don't negotiate

For every supplier that lands in the bottleneck quadrant: look now, while nothing is wrong, for a second contact or a fallback option. Waiting until the supplier actually disappears is exactly the moment you no longer have time to search calmly.

Strategic: lock in what you have

For suppliers scoring high on both risk and impact: a multi-year contract, a personal conversation about their own continuity (are they selling the business? retiring?), and an agreement about what happens if problems arise — knowing a problem is coming early is half the fix.

Leverage: use your power now

These are the suppliers where the seven negotiation tactics actually work — you have alternatives here, so applying pressure costs you nothing.

Action plan

This week: work out the spend share for your three biggest suppliers — the last three months of invoices, totalled per supplier, divided by the overall total.

This month: place every supplier on the Kraljic map above. For every bottleneck supplier: find a second contact, or work out how much backup stock is reasonable given their switching time.

This quarter: for your strategic suppliers — high risk and high impact — schedule a conversation that isn't about price: how's their business doing, what are their own plans, and what would they want you to know earlier next time.

Conclusion

Negotiating is the conversation you have once you already know who you're talking to. The three numbers above — switching time, spend share and the Kraljic quadrant — are the conversation that comes before it: knowing who you genuinely can't afford to lose, before that supplier makes you find out on the worst possible day.
