Why this matters
If your offering depends on goods, materials, production, machinery, software, or external partners, procurement determines your price, quality, ability to deliver, and capital requirements. A great-looking shop won't help much if purchasing and delivery haven't been planned realistically.
Turn knowledge into a start plan
This guide explains one topic. Whether it is really a priority for you right now depends on your answers in the start plan.
Create start planSuppliers Are Part of Your Business Model
For physical products, a supplier is more than just a source of goods. They influence your purchase price, minimum order quantity, quality, delivery time, product images, product data, returns, payment terms, and sometimes even which sales channels you are allowed to use.
Procurement can also matter for service-based businesses: machinery, tools, software, raw materials, external freelancers, packaging, or fulfillment can all determine whether your offering actually works reliably day to day.
The most important question is therefore not: where can I get it cheapest? But rather: which procurement approach fits my starting budget, my target customers, my quality expectations, and my ability to deliver?
Manufacturer, Importer, Wholesaler, or Platform?
Buying directly from a manufacturer or importer can be attractive, but it often comes with higher minimum order quantities, longer lead times, or more complex coordination. Wholesalers and distributors are usually more accessible, though the purchase price is not always the lowest.
B2B platforms and marketplaces can be useful for research, but they do not replace your own due diligence: who is behind the supplier, what quality is actually delivered, what documentation exists, what language is spoken, and what does the real process look like when it comes to complaints or reorders?
For a side business in Germany, the best first supplier is often not the cheapest one, but the one with whom you can test on a small scale, cleanly, and repeatably.
Understanding Terms Before You Order
Clarify the minimum order quantity (MOQ), minimum order value, tiered pricing, shipping costs, delivery time, payment terms (Zahlungsziel), return policy, handling of damaged goods, reorder process, and whether you are permitted to use product data or images.
Do not just compare the purchase price against the selling price. Packaging, shipping, platform fees, payment processing fees, returns, damaged goods, storage, taxes, marketing, and your own time all need to be factored into your calculation.
Especially for small side businesses, an order can look profitable on paper and still tie up too much capital if the goods sell slowly.
Testing Quality and Reliability
Whenever possible, order samples or small test quantities before committing to larger volumes. Check not only whether the product looks good, but whether it genuinely suits your intended use case, shipping conditions, customer expectations, and price point.
Document any differences between the sample and subsequent deliveries. Especially with own-brand products, private labels, or imports, quality in the second batch can differ from what you saw in the first contact.
If a supplier is critical to your business, plan for alternatives. A single supplier can become a risk through outages, price changes, long delivery times, quality problems, or changed terms.
What Belongs in Your Planning
For your business planning, you do not need a perfect purchasing department. You need a solid first overview: what do you need, from whom, on what terms, with what delivery time, and with what risks?
This information belongs directly in your business plan, capital requirements, pricing logic, and risk analysis. Only then does it become clear whether your offering can realistically be sold.
Quick checklist
- Do you need goods, materials, production, machinery, software, or external partners?
- Do you know the minimum order quantity, minimum order value, and delivery time?
- Have you checked samples or small test quantities?
- Have you clarified image rights, product data, and permitted sales channels?
- Have you realistically calculated purchasing costs, fees, shipping, returns, and storage?
- Is there a second supplier or a backup plan?
Common mistakes
- Choosing suppliers based solely on the lowest purchase price.
- Buying large quantities before demand and quality have been verified.
- Using product images or data without clarifying usage rights.
- Only noticing minimum order quantities, payment terms, and storage costs after placing the order.
- Making your entire business model dependent on a single supplier.
