Introduction

Every retailer knows the feeling: a customer asks for a product you normally stock, and the shelf is empty because the supplier did not deliver. Or a carton arrives with crushed packs and short dates, and it takes weeks of phone calls to get a replacement. Or the quotation looked cheap, but extra charges, minimum orders and slow-moving stock made it expensive in the end.

Choosing a wholesale supplier is one of the most important decisions a retailer, restaurant or hotel makes. A good supplier keeps shelves and kitchens stocked, protects your reputation and helps you grow. A poor supplier costs money, time and customers.

As a wholesale supplier of food and non-food brands ourselves, we know what good supply looks like from both sides. This guide explains what to look for in a supplier, which questions to ask, how to compare quotations beyond price, the warning signs to watch for and a simple scorecard to help you decide. It is useful whether you run a supermarket, a neighbourhood shop, a pharmacy, a restaurant, a café or a hotel.

Why the choice matters

A supplier affects your business in many ways:

• Availability. If deliveries are late or short, shelves and store rooms run empty, and customers go elsewhere.
• Quality. Poor-quality or damaged products disappoint customers and damage your reputation.
• Compliance. Products with incomplete labels or unsafe handling create legal and safety risks.
• Cash flow. Minimum orders, payment terms and slow-moving stock affect how much money is tied up in your business.
• Time. Chasing deliveries, correcting invoices and arguing about damages takes time away from serving customers.

The cheapest supplier is not always the best value. The right supplier is the one that delivers good products reliably, at a fair total cost, and treats you as a long-term partner.

Twelve signs of a reliable wholesale supplier

1. Consistent quality. Products match the samples you approved, every time.
2. Reliable deliveries. Orders arrive on the agreed day, complete and in good condition.
3. Clear written quotations. Prices, pack sizes, minimum orders, delivery and payment terms are set out in writing.
4. Accurate documents. Delivery notes and invoices match what was delivered.
5. Good remaining shelf life. Food products arrive with enough time to sell before their best-before dates.
6. Compliant labels. Packaged foods carry the information required by Sri Lanka’s labelling rules.
7. Product knowledge. The supplier can explain what products are, how they are made and how they should be stored and used.
8. Honest communication. You hear early about delays or shortages, with a suggested alternative.
9. Fair problem-solving. Damaged, wrong or short deliveries are put right quickly.
10. Flexibility. Order sizes, mixed cartons and delivery schedules suit your business.
11. Stability. The supplier has been operating for some time and can show it has the stock and systems to supply you.
12. Support to sell. Product information, images, display materials and promotional support help you sell more.

Questions to ask a new supplier

Before you place a first order, ask:

• About products: Can I see samples? What are the ingredients, allergens and storage needs? What is the shelf life, and how much will remain on delivery?
• About supply: How often can you deliver to my area? What happens if an item is out of stock? Can you supply more before festive seasons?
• About orders: What is the minimum order? Can I mix products in one carton? How do I place orders?
• About money: What are the prices and payment terms? Are there any extra charges for delivery or small orders?
• About problems: What happens if products arrive damaged, wrong or short-dated? How quickly are they replaced?
• About the business: How long have you been supplying? Who are your typical customers? Who is my contact person?

A reliable supplier will answer clearly and confirm the important points in writing.

Comparing quotations beyond price

Two quotations with similar prices can lead to very different costs. Compare:

Think about the total cost of working with a supplier, including the cost of problems, not just the price per pack.

Checking quality before you commit

Ask for samples

Samples let you check quality, taste, presentation and packaging. For food service, chefs should test ingredients in their own recipes. For retail, check how packs look on your shelves and whether labels are clear.

Start with a trial order

A small trial order shows how the supplier performs in practice: whether deliveries arrive on time, whether documents are accurate and whether products sell.

Check labels

For packaged foods, check that labels show the product name, ingredients, net contents, dates, the manufacturer or packer and other required information. Sri Lanka updated its Food (Labelling and Advertising) Regulations in 2026, so labels should reflect current rules.

Check the first delivery carefully

Count cartons, check dates and pack condition, and compare the delivery note and invoice with your order. How the supplier responds to any problem on the first delivery tells you a lot.

Warning signs

Be cautious if a supplier:

• will not provide samples or written quotations;
• delivers products with short dates or damaged packs, and is slow to replace them;
• often delivers late or short without warning;
• changes products, pack sizes or prices without telling you;
• cannot answer basic questions about ingredients, allergens or storage;
• sells packaged foods with incomplete or unclear labels;
• makes health claims that sound too good to be true, especially for herbal or wellness products; or
• is hard to contact when something goes wrong.

One mistake is not always a warning sign; every supplier has occasional problems. What matters is how quickly and fairly they are put right.

A simple supplier scorecard

Score each supplier from 1 (poor) to 5 (excellent) on the points that matter most to your business:

Review the scores every few months. A supplier that scores well consistently deserves more of your business; one that scores poorly needs a conversation or replacing.

Negotiating fairly

Good terms help your business, but pushing a supplier too hard can backfire if it leads to cut corners or unreliable service. Fair negotiation focuses on value for both sides:

• Be clear about your needs. Explain your expected volumes, delivery needs and seasonal peaks. Suppliers can offer better terms when they can plan.
• Negotiate the whole package. Price matters, but so do payment terms, delivery frequency, minimum orders, promotional support and replacement terms.
• Offer something in return. Regular standing orders, prompt payment or a larger share of your business may justify better terms.
• Get it in writing. Confirm agreed terms in a quotation or agreement, so there are no misunderstandings later.
• Review regularly. As your business grows, revisit terms together.

Managing the relationship after you choose

Choosing a supplier is the start of a relationship, not the end of the decision. To get the best from it:

• Communicate early. Share plans for festivals, promotions, new branches or menu changes in good time.
• Order consistently. Regular, predictable orders help suppliers plan stock and deliver reliably.
• Pay on time. Prompt payment builds trust and goodwill, and may help when you need flexibility.
• Give feedback. Tell your supplier what is working and what is not. Good suppliers welcome feedback.
• Report problems quickly. Issues reported promptly, with photos and details, are easier to resolve.
• Hold regular reviews. Every few months, look together at what sold, what did not and what to change.

The best supplier relationships feel like partnerships, where both sides want the other to succeed.

Planning for the unexpected

Even good suppliers can face disruption from weather, transport problems, shortages of raw materials or sudden surges in demand. Protect your business by:

• Keeping safety stock of your most important products, especially before festive seasons;
• Knowing your alternatives, so you can source critical items elsewhere if necessary;
• Asking about contingency plans, such as how the supplier handles stock shortages; and
• Watching seasonal risks, such as crop seasons for agricultural products like cashews, tea and fresh produce.

A supplier that warns you early about possible shortages, and suggests alternatives, is worth a great deal.

Responsible sourcing

Shoppers increasingly care about where products come from and how they are made. When choosing suppliers, consider:

• Origin. Can the supplier tell you where products come from? Brands that grow their own crops, for example, can trace products back to the plantation.
• Honest claims. Are product descriptions accurate, without exaggerated health or environmental claims?
• Packaging. Does the supplier offer reusable or reduced packaging options, such as reusable bags or bulk packs for kitchens?
• Fair dealing. Does the supplier treat its own workers, growers and partners fairly?

Responsible suppliers help retailers meet customers’ rising expectations and protect their reputation.

One supplier or many?

Some retailers use many suppliers, each for a few products. Others consolidate with fewer suppliers who can supply several categories. Each approach has advantages:

• Many suppliers give choice and reduce dependence on any one supplier, but mean more orders, deliveries, invoices and relationships to manage.
• Fewer suppliers save time and paperwork, may bring better terms for larger orders and make communication simpler.

Many businesses find a balance: a few key suppliers for their main categories, and specialists for particular needs. A supplier that offers both food and non-food brands, on one order and one invoice, can simplify buying without limiting choice.

A step-by-step plan for choosing a supplier

If you are looking for a new supplier, this simple plan keeps the process organised:

1. List your needs. Write down the products, quantities, delivery frequency and any special requirements, such as printed bags or catering packs.
2. Find two or three candidates. Ask other business owners for recommendations, look at suppliers’ websites and contact them.
3. Ask the key questions. Use the questions earlier in this guide and note the answers.
4. Request samples and quotations. Compare them side by side, looking at quality and total cost.
5. Score the suppliers. Use the scorecard to compare them fairly.
6. Place a trial order. Test the best candidate with a small order and check the delivery carefully.
7. Decide and agree terms. If the trial goes well, agree terms in writing and set up a regular ordering pattern.
8. Review regularly. Keep scoring performance and talk to your supplier about improvements.

Following these steps takes a few weeks, but it can prevent months of problems later.

Questions suppliers will ask you

A good supplier will also want to understand your business. Be ready to answer:

• What type of business are you, and who are your customers?
• Which products interest you, and in what quantities?
• How often will you order, and where should deliveries go?
• What are your receiving hours?
• Do you have seasonal peaks or special events coming up?

Clear answers help the supplier give you an accurate quotation and plan stock for you.

Special considerations for different businesses

Supermarkets

Look for suppliers who can provide barcodes, product data, shelf-ready cartons, delivery to stores or distribution centres, and promotional support. Insights Article 5 explains supermarket supply.

Restaurants, hotels and cafés

Look for consistent ingredients, bulk and catering packs, allergen information and deliveries outside busy service hours. Insights Article 4 explains food service supply.

Pharmacies and Ayurveda shops

For herbal and Ayurvedic products, look for a clear origin, honest descriptions of traditional use and good packaging. Avoid products sold with promises to cure disease.

Small shops

Look for practical order sizes, mixed cartons, regular deliveries and fast replacements. Insights Article 6 explains how we supply small shops.

Illustrative example

The following example is illustrative and does not describe a real business.

A restaurant owner is unhappy with the spices from a current supplier: the flavour varies from batch to batch, and deliveries are often late. The owner asks two suppliers for samples and quotations. One quotation is slightly cheaper per kilogram, but it requires a large minimum order and charges for delivery. The other is slightly higher per kilogram but has no delivery charge, smaller order quantities and a clear replacement policy.

The chef tests both sets of samples in the restaurant’s signature curries. After scoring both suppliers on quality, delivery, terms and support, the owner chooses the second supplier for a trial month. Deliveries arrive on time, the curries taste consistent, and the restaurant moves its full spice order to the new supplier.

Frequently asked questions

Should I always choose the cheapest supplier?

No. Consider total cost, including delivery charges, minimum orders, payment terms, shelf life and the cost of problems, as well as quality and reliability.

How many suppliers should a small shop have?

It depends on the shop, but many find that a few reliable suppliers covering their main categories are easier to manage than many small ones.

Is a trial order a good idea?

Yes. A trial order shows how a supplier performs in real conditions before you commit to larger orders.

What should I do if a supplier keeps delivering late?

Raise it clearly, in writing if necessary. If the problem continues, compare alternatives using a scorecard.

What documents should come with a delivery?

A delivery note and invoice that match your order, showing products, quantities and amounts.

How often should I review my suppliers?

Every few months is a good rhythm, with a fuller review once a year. Use a simple scorecard so reviews are based on facts rather than impressions.

Is it better to buy from a brand owner or a distributor?

Both can work well. Brand owners often know their products in more depth and control quality directly, while distributors may offer a wider choice of brands. Many retailers use both.

Should I sign a long-term contract with a new supplier?

It is usually wiser to start with a trial order and a short review period. Once the supplier has proved reliable, a longer agreement can make sense for both sides.

Conclusion

A reliable wholesale supplier delivers consistent products on time, with accurate documents, good shelf life, clear information and fair problem-solving. Choosing one takes a little effort: asking the right questions, comparing total costs, testing samples and trial orders, and reviewing performance regularly. That effort pays back many times over in full shelves, happy customers and less stress.
