For a lot of B2B buyers, the hardest part of switching or adding an ingredient supplier isn’t the product itself it’s the uncertainty of the process. How many calls will this take? What documentation will we need to provide? How long until product actually arrives? At Waves, we’ve tried to make that process as transparent and predictable as possible. Here’s what it actually looks like step by step.
Step 1: The Discovery Call
Every relationship starts with a conversation, not a quote. Before we talk pricing or volumes, we want to understand what you’re actually trying to solve: Is this about diversifying supply risk? Reformulating a product? Replacing an underperforming supplier? Launching something new?
We also come prepared. If we’ve reached out to you first, we’ve usually already looked into what your business does, what’s publicly known about your recent activity, and where we think there might be a genuine fit so the call is a conversation, not a cold pitch read off a script.
Step 2: Understanding Your Specification
Once we know what you need, we get specific: target specification, required certifications (organic, kosher, halal, non-GMO), volume expectations, delivery frequency, and any regulatory documentation your own downstream customers require from you. This is also where we flag anything that might affect sourcing origin constraints, seasonal availability, or current market conditions that could affect pricing or lead time.
Step 3: Samples and Documentation Exchange
Before any commercial commitment, you’ll typically receive:
A product sample, sized appropriately for your own testing and evaluation
A full specification document, formatted and ready for your own technical review
A Certificate of Analysis (CoA) for the specific batch or a representative recent batch
Any relevant compliance documentation organic certification, allergen statements, origin documentation, EUDR-relevant traceability data where applicable
We’d rather send more documentation than you need than have you come back with follow-up requests that delay your own internal approval process.
Step 4: Commercial Terms and Agreement
Once the product itself checks out, we move to commercial terms: pricing structure (fixed, indexed, or hybrid), minimum order quantities, payment terms, and delivery logistics. For buyers who want price stability given ongoing market volatility, we’re open to discussing longer-term supply arrangements rather than pure spot pricing worth raising early if that’s a priority for you.
Step 5: First Order and Quality Verification
Your first order is usually treated as a verification step as much as a commercial transaction. We’d encourage running your own incoming quality checks against the CoA provided, and we stay available during this window specifically in case anything needs clarifying quickly, rather than routing you through a general support queue.
Step 6: Ongoing Account Management
Once the first shipment lands successfully, the relationship shifts from onboarding to account management: a consistent point of contact, regular check-ins on volume and forecasting, and proactive flagging if something in the market a price movement, a supply risk, a regulatory change is relevant to what you’re sourcing from us.
What This Looks Like in Practice
Most buyers move from first call to first shipment within a matter of weeks, not months though that timeline naturally depends on the complexity of the specification, any custom documentation requirements, and your own internal approval processes. The goal on our end is never to be the bottleneck.
The bottom line
Onboarding a new supplier shouldn’t feel like a leap of faith. A clear, documented process sample first, full documentation before commitment, transparent commercial terms is what makes it possible to move quickly without cutting corners on the diligence that actually matters.
