How It Works · International B2B Sourcing
From buyer briefto verified route.
CeyLanka's sourcing process is designed around a simple principle: commercial promises should follow the product specification, source evidence and destination route — not come before them.
The journey below shows what a buyer provides, what CeyLanka returns, where samples or tests may be useful, how a quotation is built and which facts are locked before execution.
The CeyLanka difference
Simple enough to understand. Detailed enough to verify.
Many supplier journeys are reduced to enquiry, sample, production and shipment. That is easy to read, but international procurement teams also need to know where identity, specifications, evidence, payment terms, destination requirements and document scope are resolved. CeyLanka keeps the journey readable without hiding those gates.
01 · The buyer journey
Seven stages.One traceable commercial route.
Each stage makes the buyer input, CeyLanka response and evidence gate visible. That makes the process easier to question, approve and repeat.
Define what you actually need.
Start with the exact product and commercial requirement rather than a generic request for the 'best quality'. For spices this can include species, form and grade; for tea, type/manufacture/grade or regional requirement; for fruit, cultivar, maturity and pack-out.
Buyer provides
- Product, form / grade / cultivar where known
- Quantity or expected volume
- Destination country
- Intended use
- Packing preference
- Quality, safety, certification or document requirements
- Target timing
CeyLanka returns
- Clarification questions
- Missing specification fields
- Initial sourcing-route direction
- Questions that must be answered before price is meaningful
At this stage the enquiry is a buyer requirement, not a stock or availability promise.
Check product and sourcing-route feasibility.
The proposed source or processor route is reviewed against product identity, form, buyer requirement and destination. If key facts are not yet supported, they remain open rather than being converted into quotation assumptions.
Buyer provides
- Answers to clarification questions
- Mandatory buyer standards or onboarding requirements
- Restricted treatments or prohibited processes
- Destination-specific information already known
CeyLanka returns
- Feasible / conditional / unresolved route status
- Source or processor evidence available for review
- Identified regulatory or evidence gaps
- Next verification actions
A supplier name, photograph or certificate logo is not treated as qualification on its own.
Align the product specification and evidence.
Buyer requirements are converted into measurable product and evidence criteria. The specification defines what should be supplied; a CoA or test report records results for the sample or lot tested; supplier or site certificates cover only their stated scope and validity.
Buyer provides
- Target physical / sensory criteria
- Microbiology, residues, contaminants or other test requirements
- Required certifications and acceptable scope
- Packing / labelling requirements
- Required test methods or laboratories where specified
CeyLanka returns
- Specification alignment status
- Available source / process / certification evidence
- Parameters that still require testing or confirmation
- Document scope and validity notes
Specification ≠ CoA ≠ certification ≠ export document. Each answers a different question.
Sample, test or validate when the route needs it.
A pre-order sample, retained sample, pilot pack or additional testing can be useful when a buyer needs sensory approval, physical validation, lab evidence or packaging confirmation. It is not presented as a mandatory ritual for every product or repeat order.
Buyer provides
- Sample purpose and acceptance criteria
- Delivery address and courier constraints
- Requested analytical parameters
- Reference sample or benchmark where relevant
CeyLanka returns
- Sample / validation plan when applicable
- Available sample or test evidence
- Results or observations against the agreed criteria
- Open deviations before commercial commitment
A sample can support approval, but final shipment evidence still has to relate to the actual commercial lot where required.
Build a quotation that says what is included.
The quotation turns verified product and route facts into a commercial offer. International quotes are only comparable when product, quantity, pack, delivery scope, payment and documentary assumptions are explicit.
Buyer provides
- Final requested quantity
- Named destination / delivery place
- Preferred Incoterms® rule if known
- Commercial payment requirements
- Required quotation validity / decision timing
CeyLanka returns
- Product / grade / form and quantity
- Pack and price basis
- Incoterms® 2020 rule + precise named place
- Payment terms
- Expected timing and quote validity
- Included tests / documents
- Key assumptions, exclusions and conditions
An Incoterms® rule allocates defined delivery tasks, costs and risks; it does not replace the product specification, payment agreement or destination law.
Lock the accepted transaction snapshot.
Once accepted, the agreed product specification and commercial terms become the working transaction snapshot. Sourcing, processing, packing, testing and documentation should execute against that accepted version rather than against changing email assumptions.
Buyer provides
- Acceptance / purchase-order information
- Final consignee / buyer details
- Payment according to agreed terms
- Approved artwork / labels where applicable
- Any final destination instructions
CeyLanka returns
- Confirmed order / transaction reference
- Locked commercial and specification snapshot
- Execution milestones where available
- Exceptions requiring buyer approval before shipment
Payment method and timing are agreed per transaction; CeyLanka does not treat one payment structure as universal for every buyer.
Export the verified route and hand over the evidence.
Applicable approvals, Customs declaration, packing, transport and shipment evidence are prepared for the actual route. After shipment, the commercial/specification snapshot and agreed document set provide the reference for reconciliation and repeat business.
Buyer provides
- Final delivery / consignee information
- Import-side instructions or broker requirements
- Any shipment-specific document instructions
- Confirmation of changes requiring approval
CeyLanka returns
- Applicable Customs / shipment status
- Agreed commercial and transport documents
- Product / lot evidence included in the agreed route
- Handover information
- Transaction reference for reconciliation / repeat enquiry
Not every shipment needs a CoA, phytosanitary certificate, COO, fumigation certificate or inspection certificate. The document set follows the product, destination, treatment, preference and buyer requirement.
02 · Quotation anatomy
What changesthe price and route.
EDB's exporter guidance explicitly treats freight, insurance, Customs / port charges, commissions, bank charges and exporter margin as part of export-pricing logic. CeyLanka therefore does not pretend one global public price can describe every buyer route.
Product identity & form
Species, grade, manufacture, cultivar, cut, particle size or maturity can change sourcing and processing cost.
Quantity
Batch size, packing efficiency and freight economics change with the requested volume.
Packing
Liners, cartons, bags, retail packs, labels, pallets and protective materials change material and handling cost.
Testing & certification
Buyer-specific lab panels, inspection, certification scope or additional evidence can add route-specific cost.
Destination & HS route
Classification, import rules, plant-health conditions and destination procedures affect the commercial route.
Incoterms® + named place
Delivery responsibilities and the point where defined cost/risk allocation changes must be explicit.
Freight & insurance
Mode, carrier, transit route, seasonality and insurance basis can materially change landed economics.
Payment & banking
Advance, L/C, documentary collection or open-account structures can carry different bank, risk and financing costs.
FX & timing
Currency exposure, lead time and quote validity influence how long a commercial price can responsibly remain open.
A comparable quotation should state
Product + quantity + pack + price basis + Incoterms® rule + named place + payment + timing + evidence scope.
03 · Evidence follows the transaction
One word called “documents”hides several different jobs.
Product evidence, analytical results, site certification, origin, plant health and transport documents are not substitutes for one another.
Product specification
Defines the agreed identity and measurable product / pack requirements.
CoA / test report
Records results for the tested sample or lot and selected analytical parameters.
Supplier / site certification
Supports only the named site, standard, scope and validity period shown on the certificate.
Phytosanitary certificate
Plant-health certification against importing-country conditions for an applicable plant-product route.
Certificate of Origin / REX
Origin or preferential-trade evidence only where the relevant origin scheme and rules apply.
Invoice / packing list
Commercial and packing records for the actual shipment.
Bill of lading / air waybill
Carrier transport evidence for the shipment mode.
Inspection / treatment certificate
Route-specific evidence only when that inspection or treatment is actually required and performed.
04 · Payment is transaction-specific
Agree the risk structure.Do not assume one method.
Sri Lanka EDB lists advance payment, letters of credit, documentary collection and open account among common export-payment methods, and notes that the choice depends on the relationship, risk and volume of business.
CeyLanka's quotation should state the agreed payment terms for the actual transaction rather than advertising one universal structure.
