Standard Cost and Assembly Posting

  • Standard Cost and Assembly Posting

    Posted by Andrea Smiley on March 17, 2026 at 4:41 pm

    Looking for guidance/documentation on the G/L Postings expected when posting an assembly when using standard cost; and the posting of the assembled item on a sales invoice for serialized item.

    There are so many entries made for 1 thing in BC – it is overwhelming to understand what should be happening.

    I have an assembly that standard cost is $10K; Assembly cost was $13K – my entry looks like it has $13K going into inventory; $3k as a credit to inventory; but then there is another $3K debiting inventory when I posted the assembly. (I would expect $10K to hit Inventory, $3K to variance in pure accounting 101 terms)

    All the standard learning and videos I have found do not get into the true weeds of this.

    Any guidance greatly appreciated.

    Hi @asmiley4ptcsolutions-com

    You’re not alone in finding this confusing, BC’s assembly posting under standard cost does look messy at first.

    What you’re seeing is actually correct. BC posts the actual cost first ($13K), then adjusts to standard in separate steps rather than netting it cleanly. The end result should still be $10K in inventory and $3K to variance; it just takes a few journal lines to get there.

    Best way to make sense of it: filter your G/L entries by the assembly order’s Document No. and read them in sequence. It becomes much clearer that way.

    Happy to help further if you can share the entries.
