Choosing a supplier based on price alone is one of the most expensive mistakes a small business can make. The cheapest option can end up costing far more when delivery is late, quality is inconsistent, or the supplier disappears when you need support.
The problem is that most small businesses don't know what else to ask. Price is easy to compare. Everything else requires knowing the right questions. This guide gives you a practical list of questions to ask any supplier before committing, organised by what they actually tell you about the supplier's reliability and fit.
Questions about capability and experience
Before worrying about price, make sure the supplier can actually deliver what you need. These questions help you filter out suppliers who look good on paper but aren't the right fit.
How long have you been providing this product or service? A newer company isn't automatically worse, but experience usually means they've encountered and solved more problems. For critical purchases, a track record matters.
Can you provide references from similar businesses? A supplier who works mainly with large corporations may not give a small business the same attention. Ask for references from companies of a similar size and in a similar industry.
What's your capacity? If you need 500 units per month and the supplier can comfortably produce 5,000, you're a small account to them. If they can only produce 600, you're at risk of delays during busy periods. Understanding their capacity relative to your needs tells you how much attention you're likely to get.
Do you have relevant certifications or accreditations? Depending on what you're buying, this might include ISO certifications, food safety standards, industry-specific accreditations, or environmental certifications. If these matter for your business or your customers, ask upfront rather than discovering a gap after you've committed.
Questions about pricing and terms
Once you know the supplier can deliver, dig into the commercial details. The goal is to understand the total cost, not just the unit price.
What's included in your quoted price? This is the single most important pricing question. Does the price include delivery? Installation? VAT? Training? Support? Packaging to your specifications? Two suppliers might quote the same product at different prices, but once you add delivery charges to one and a setup fee to the other, the comparison shifts entirely.
What are your payment terms? Net-30, net-60, payment on delivery, or something else? If cash flow is tight — and for most small businesses it is — payment terms can be as important as the price itself.
Are there discounts for volume or long-term commitment? Many suppliers offer better pricing if you commit to a certain quantity per month or sign a longer-term agreement. It's worth asking, even if you're not sure you want to commit yet, because it gives you a sense of where their flexibility lies.
How do you handle price increases? Suppliers don't always keep prices the same. Understanding how and when they adjust pricing helps you plan and avoid surprises. Some give 90 days' notice. Others adjust quarterly with no warning.
Questions about delivery and reliability
A supplier who delivers the right product two weeks late is arguably worse than one who is slightly more expensive but consistently on time. These questions help you gauge reliability.
What's your standard lead time? Know this before you need something urgently. If their standard lead time is six weeks and you usually need things in two, this isn't the right supplier for time-sensitive orders.
Can you handle rush orders, and what do they cost? Every business has emergencies. Knowing the cost and feasibility of expedited delivery before you need it is much better than finding out during a crisis.
What happens if something goes wrong? This is the question most people forget to ask. What's the process for returns, replacements, or corrections? How quickly can they resolve issues? A supplier's response to problems tells you more about them than their sales pitch ever will.
Questions about communication and support
The relationship with a supplier matters, especially for ongoing purchases. These questions help you understand what the working relationship will actually feel like.
Who will be my main point of contact? Will you deal with the same person each time, or get passed around? For small businesses, a named contact who knows your account makes a significant difference in day-to-day operations.
How do you prefer to communicate? Some suppliers are great on email. Others prefer phone calls. Some use client portals. Make sure their communication style matches how you like to work.
Let AI ask the right questions for you
When you create a project in RFXapp, AI suggests the evaluation questions that matter most for what you're buying. Add your own, and every supplier gets the same set. Their answers are tracked and compared automatically.

You don't need to ask every question to every supplier. Pick the ones that matter most for your specific purchase and make sure every supplier gets the same questions. This way, you can compare apples to apples.
The best approach is to send your requirements and questions to several suppliers at once, then compare their responses side by side. When everyone answers the same questions, the differences become obvious — and so does the right choice.
