How to Send a BOM So It Can Be Quoted: Formats, Abbreviation

How to Send a BOM So It Can Be Quoted: Formats, Abbreviations, and What Speeds Up the Reply

A BOM sent for line-by-line quoting is most useful when the part number or marking text is visible on every line, the quantity per line is stated, and any preferred-alternative note from engineering is included. The format matters less than line-by-line completeness — Excel, PDF or a photo of a handwritten sheet are all readable. Ambiguous lines should still be sent; identifying the line is part of the work, not a prerequisite. The reply is faster when the list is unambiguous, and a per-line condition, MOQ, lead time and price are returned rather than one blended figure. We are an independent industrial automation distributor and sourcing desk based in China.

FAQ

What is the most useful format to send a BOM in?

Any format in which every line is identifiable — Excel, PDF, a photo of a handwritten sheet, or an ERP export. The format itself matters less than whether each line carries either a part number or enough marking text to be matched, plus the quantity per line.

Do I need to clean up the BOM before sending it?

No. Send the list as it stands, including typos, abbreviations and lines you are unsure about. Where a line is ambiguous the desk comes back with a clarifying question rather than filling in its best guess into the quote.

What does the desk need from me to start the quote?

The part number or the marking text, the quantity per line, and any preferred-alternative note your engineering team has already approved. If a line is ambiguous — a partial number, a description only, a photo — send it anyway; identification is part of the work, not a prerequisite for it.

Will the desk read an English BOM full of internal codes?

Usually yes, but the desk would rather ask than guess. Where an abbreviation is ambiguous — a partial order number, an internal code, a description that matches several product families — the desk comes back with a clarifying question instead of filling in its best guess into the quote.

Can the desk quote a partial BOM and add the remaining lines later?

Yes. Many orders start as a partial BOM because the machine is down and only the blocking lines matter today. The remaining lines can be quoted and ordered later; prices and availability are re-checked at the time of each order rather than held from the first quote.

How long does a BOM quote take?

Single-line and short-list requests are usually answered the same working day; a long mixed-brand list takes longer because each line is sourced individually. The desk does not quote a fixed turnaround as a service guarantee — the response time depends on the list and on how quickly suppliers confirm.

What does the desk send back?

A per-line table: each line gets its own price, MOQ, lead time and condition (new, new surplus, refurbished or used). That lets you drop or defer individual lines instead of rejecting a whole quote, and it means a single expensive line cannot hide inside a lump sum.

The Shape of a BOM That Gets Quoted Quickly

A BOM that gets quoted quickly is not a tidy BOM; it is a complete BOM. Tidiness is a presentation preference; completeness is a quoting requirement. The difference between the two matters because the desk works the list line by line, and a line that has to be identified before it can be sourced is a line that holds up the rest of the reply.

Three pieces of information per line are the working minimum. The first is the part number or, where the part number is missing or partial, the marking text that is legible on the label, the housing or the connector face. The second is the quantity per line. The third is any preferred-alternative note the engineering team has already approved. With those three pieces the desk can move the line from identification to sourcing to quote without coming back to ask.

Three more pieces of information make the reply faster. The first is the brand or family when it is not encoded in the part number — a panel-shop BOM that says "24 VDC relay, 10 A, DIN rail" without a brand carries an identification cost. The second is the target machine or panel — "for the control panel of machine X, spare parts list revision 3" lets the desk cross-check the list against the machine's spare-parts book. The third is any deadline context — a machine-down line, a commissioning date, a service window — because that changes which channel the desk looks at first.

The line that is hardest to quote is the line that has only a description. "Inductive sensor M12, 4 mm, PNP NO" is identifiable from a catalog search; "sensor for machine X" is not. The desk will work on the first line immediately and will come back with a question on the second. Sending the BOM as it stands — including the second line — is the right move; cleaning up the second line into a guess before sending it is the wrong move, because the guess is what ends up in the quote.

Part Numbers, Marking Text, Descriptions — How the Desk Reads Each

Part numbers are the cheapest line to source. A complete part number that resolves to a known series goes straight into the desk's matching table, and the desk returns a per-line price, MOQ, lead time and condition. A panel shop sending 40 lines that all carry part numbers is the case where the reply comes back fastest.

Marking text is the next layer down. A line that has no part number but has a clear marking on the label — a Phoenix Contact order number on the side of a relay, a Siemens 6ES7 number printed on a CPU, an Omron E3Z part code on a photoelectric sensor — is identified from the marking by matching the visible text against the catalog. The desk can usually identify a marked unit from the marking alone, but it adds one step: the desk has to read the marking before it can source the part. Where the marking is illegible (a worn label, a covered serial plate) the desk comes back with a request for a closer photograph or a clearer image.

Descriptions are the layer where identification work is highest. "24 VDC relay, 10 A, DIN rail, LED indicator, 1 changeover" narrows the field but does not pin a brand. "Littelfuse fuse, 250 V, 200 A, time-delay, blade" narrows further because the manufacturer is named. "Fuse for machine X, line 12 of the spare-parts list" is not identifiable without the spare-parts list. The desk works the first two descriptions immediately and comes back with a question on the third.

Three formats that combine these layers well. The first is an ERP export with part number, quantity and short description on every line — the desk reads it as-is. The second is a PDF of a marked-up diagram or a typed list, where the part number is on one line and the quantity on the next; the desk reads both. The third is a photo of a handwritten sheet, where the writing is legible enough to read the part number; the desk reads the marking rather than guessing at the handwriting.

Abbreviations and Internal Codes

Abbreviations and internal codes are where BOMs start to look opaque to a desk that is not in your company. A part number that ends in "/2" in your system may be a different revision in the manufacturer's system. An internal code like "FB-A14" may map to a particular Littelfuse FLSR200 fuse in your spare-parts list and to nothing in any catalog. The desk does not assume either case; it asks.

Five kinds of abbreviation show up repeatedly. The first is the project prefix — a BOM for a specific machine line might prepend every line with a project code ("AB12-", "K22-") that does not appear in any manufacturer catalog. The second is the unit prefix — "PCS" for pieces, "EA" for each, "STK" for Stück (German for pieces), "шт" for штук (Russian for pieces). The third is the size or rating shorthand — "20A" for a 20-ampere breaker, "10kA" for a 10-kiloampere interrupt rating, "M12" for an M12 connector. The fourth is the assembly-vs-component distinction — a line marked "ASSY" is an assembly made up of components; the desk treats it as one line unless you ask for the components to be broken out. The fifth is the supplier abbreviation — "Mfr: Schneider" or "Vendor: Phoenix" on lines that otherwise look like generic catalog entries.

A BOM that includes a one-page legend at the top — project codes, unit prefixes, rating shorthand, assembly rules, supplier abbreviations — saves the desk five to ten minutes of back-and-forth and shortens the reply by a working day. The legend is more useful than the BOM being perfectly formatted; the desk can read a messy list, but the desk cannot read a list whose codes are opaque.

Where a code is opaque and the legend is missing, the desk comes back with a clarifying question rather than guessing. The guess would end up in the quote and the wrong unit might be sourced. The clarifying question is the slower path, but it is the path that returns a usable quote.

Mixed Formats: PDF, Excel, Photos, ERP Exports

The desk reads the line item whatever format you have. The format is not the source of delay; the readability of each line within the format is.

Excel and CSV exports are the cheapest format to quote from. Each row is a line; each column is a field. The desk runs the list through its matching table and returns a per-line quote. Where the export includes columns the desk does not need (revision history, last-purchase date, supplier-of-record) the desk ignores them. Where it omits the part number or the marking, the desk comes back with a question.

PDFs of typed lists work the same way as long as the text is selectable rather than scanned. A scanned PDF where the text is an image adds an identification step: the desk reads the image first and then matches what it read. A scanned PDF where the image is also low-resolution is the slowest format, because the desk has to come back with a request for a clearer copy.

Photos of typed pages are equivalent to scanned PDFs in practice. Photos of handwritten pages are slower but workable when the handwriting is legible. The desk can read "6ES7 315-2AH14-0AB0" in handwriting; the desk cannot read "S7-300 CPU" in handwriting and assume the full part number. Where the handwriting is unclear, the desk comes back with a request for the typed reference or the original document.

ERP exports are usually clean but occasionally include system-only fields (internal stock codes, supplier-of-record codes) that the desk cannot interpret. The desk reads the part number, the description and the quantity, and ignores the rest. Where the ERP export includes only an internal stock code and no part number, the desk comes back with a request for the underlying manufacturer part number.

Partial BOMs and Ambiguous Lines

Many orders start as a partial BOM. A machine is down; the lines that matter today are the lines that replace the failed unit; the remaining lines can wait. Sending the partial BOM — even a three-line partial — is the right move; the desk starts sourcing those three lines immediately.

A partial BOM is also a way to test the desk. If the first three lines come back with a per-line quote that matches your expectations, you can send the remaining lines and know the desk reads the format correctly. The reverse is also true: a quote that returns a blended figure or a wrong unit is a signal to clean up the list before sending the rest.

Ambiguous lines — a partial number, a description only, a photo only — are not a reason to hold the BOM back. Send the line as it stands; the desk identifies the line as part of the work. A photo of a marking is enough for the desk to identify most catalog parts; a description alone sometimes is enough if the brand and the rating are named; a partial number usually requires a clarifying question because the desk would otherwise have to choose between two or more candidates.

The desk prefers to ask than to guess. A guess would end up in the quote as a definite item; a clarifying question returns a line-by-line table where every line is the line you intended. The cost of the clarifying question is a half-day of back-and-forth; the cost of a wrong guess is a wrong unit on the dock.

What Comes Back on the Quote

The quote per line, not per order. Each line gets its own price, MOQ, lead time and condition. The table is built so that a single expensive line cannot hide inside a blended figure, and so that any line can be dropped or deferred without rejecting the rest of the quote.

The condition column uses three words. New surplus is unused stock sourced outside the manufacturer's franchised channel and carries whatever warranty the channel provides. Refurbished units are bench-tested and the result is recorded against the serial number; the warranty is the one stated on the quotation for that specific line. Used units are inspected and shipped as pulled; they are not described as tested, and they are not described as refurbished. Condition is stated per line, and the desk does not describe the lot as a whole.

The MOQ column is the upstream supplier's MOQ for the specific line. The desk does not set a site-wide minimum; the desk quotes per line because the upstream MOQ varies from one piece to a full pack depending on the part. Where a supplier will only sell a sealed pack, the desk says so and quotes the pack rather than presenting the pack as a per-piece minimum.

The lead time column is per line and per supplier, not per order. Where the lines have different readiness times, the desk offers to wait for the slowest line or to ship in two batches; the choice is yours when you confirm the quote.

The price column is per line for the quantity you asked for. Discounts on repeat orders are handled per line by the supplier rather than by an announced schedule, and repeat pricing is re-quoted at the time of ordering. The desk does not hold a price from one quote to the next because the channel moves.

What Slows the Reply Down

Five things slow the reply down. None of them is the format. All of them are about what is on each line.

The first is a partial number that resolves to more than one catalog part. "Siemens 6ES7 315" matches several S7-300 CPU variants; the desk comes back with the question. The clarification is a half-day; the fix is to send the full part number, including the order suffix, when the BOM is exported from the machine's spare-parts list.

The second is a description without a manufacturer or a brand. "Photoelectric sensor, M18, 10 m, PNP" is a description; it is not a part number. The desk can narrow the candidates but cannot pin one without a brand. The fix is to read the brand off the existing sensor on the machine and add it to the line.

The third is a typo on the part number that takes the line out of the catalog entirely. "6ES7315-2AH14-0XBO" with an O instead of a 0 is a character the desk will not find. The fix is to send the BOM as it stands and let the desk come back with the typo identified; the desk does not silently correct typos.

The fourth is a unit prefix that is not in the desk's known list. "KPL" for Komplett (a complete assembly in German) is not standard; the desk comes back to confirm whether the line is the assembly or a component of the assembly. The fix is a one-line legend at the top of the BOM.

The fifth is a deadline that is not stated. A line that is marked "URGENT" is read as urgent; a line that is the only thing standing between a machine and a working day is read as another line. The fix is to flag the lines that are blocking the machine in the body of the email or at the top of the BOM. The desk reads the message text as well as the list.

The Honest Boundary

The desk is an independent distributor and sourcing desk, not an authorized distributor of any manufacturer, and the desk works across the supply chain rather than inside it. The desk screens end users and end uses, classifies before quoting, and declines transactions that cannot be screened. The desk does not hold EAC or TR CU certification, and conformity assessment for the destination market is arranged by the importer. The desk does not provide customs, sanctions or certification advice.

The per-line quote is what the desk can attest to about each line on the day the desk quotes it. Condition, MOQ, lead time and price are stated per line and re-checked at the time of each order. A line that is used or refurbished carries a per-line warranty; a line that is used-as-pulled carries whatever warranty the quotation states; a line that is new surplus carries whatever the channel provides. The desk does not transfer a manufacturer's warranty where one did not exist before.

Engineering responsibility stays with you. The desk reads the BOM and returns a per-line table; the desk does not certify that the line is the right line for your application, that your program will run on a different controller, that an equivalent is compatible, or that the unit will survive your specific environment. That judgement belongs to your engineering process and your quality system. The desk's job is to make the per-line table as accurate as the channel allows and to come back with a clarifying question rather than a guess when the list is ambiguous.
