A real parts order does not arrive as a clean table. It arrives as a mixed list: 180 lines, four brands, some numbers transcribed by hand, a few carrying replacement references, and a handful copied from an old invoice in the hope they are still current. What separates a controlled sourcing workflow from an uncontrolled one is how that list is handled before anything is quoted.
Each stage below exists to catch one specific failure. Take one stage out, and its failure reappears later, at the container.
Stage 1: the list is normalized before it is quoted
Every line is split into OE number, brand and quantity. Numbers stay exactly as received, including letter suffixes and separator differences: one market writes 45022-TVA-A00, another catalogue drops the hyphens, and both describe the same part. The list keeps the two spellings as separate lines until the match is confirmed, so nothing is merged or corrected by assumption.
The first pass also flags duplicates, transcription errors and numbers that exist in no catalogue. A line that cannot be resolved is reported back as unresolved. It is neither dropped silently nor priced from a guess.
Stage 2: each number is checked against fitment records
A number is only as useful as its fitment context. Each line is checked against the catalogue records that map OE numbers to vehicles: which models the number covers, across which years, and whether a replacement number exists for it.
Where the number resolves, the line comes back with its models and years attached. Where only a replacement number matches, the replacement is noted explicitly, so the buyer can confirm it rather than discover it after arrival. Where nothing matches, the line is set aside for rechecking. In most lists that means one or two transcription errors, occasionally a number that was never valid; the workflow tells the buyer which, instead of silently choosing for them.
Stage 3: the quote is built line by line
A controlled quote prices each line separately rather than averaging the list. Quantity changes the tier, so the same number at one piece and at fifty pieces sits on two different price lines. A line with no confirmed match is priced at zero and stated as such. The buyer can read the gaps directly, and the gaps are the point: they show what still needs a photo, a VIN or a corrected number before the order can be complete.
Stage 4: packing follows the list
Every line that ships is checked against the confirmed quantities before packing. Fragile and electrical parts are separated; carton marks follow the packing list; and the packing list and commercial invoice must agree line by line, because the destination customs and the buyer’s own warehouse will compare them on arrival.
Stage 5: export handover with evidence
The handover carries what the forwarder needs — commercial invoice, packing list, transport document — and what stays useful after arrival: photographs of labels and markings, carton marks and batch references. A claim that arrives with this evidence is resolved quickly. One that arrives without it becomes a dispute, and the workflow exists so that disputes stay rare.
Why the order of the stages matters
Normalization catches transcription drift. Fitment checking catches the wrong-variant match. Line-level quoting catches hidden gaps. Packing checks catch shortage and damage. The export handover makes the remaining problems resolvable. Skipping a stage does not save time; it moves the cost downstream to the container arrival, where it is paid in full.
A checklist for sending a mixed list
- OE numbers exactly as received, one line per variant
- Brand and model context where known
- Quantities per line
- Replacement or cross-reference numbers where they exist
- Destination and required documents
- Photos of labels for any line you are unsure about
Send the mixed list to our quotation desk and it returns line by line: matches with fitment, replacement numbers where they apply, and unresolved lines stated separately. The same discipline applies when checking a single number — the vehicle information that belongs with an OE number is the difference between a one-round quote and three rounds of questions. Browse the catalogue by part number or by vehicle model to see how each line resolves before you send it.
