Change how discounts are calculated?

  • Hi there.

    This is an odd question. I’m testing this with my accounting software to make sure the totals generated in online orders match the totals generated by our system.

    After some digging, I’m finding that my system is calculating bulk pricing differently than the plugin. For instance, if a product is normally $30, and bulk discount is half off, my system would calculate the subtotal by multiplying the bulk sale price by X units directly. I think the plugin is taking the original price ($30), multiplying that by X units, and taking the discount off the end.

    Is there any way to tweak it so that subtotals are calculated based directly on sale price, or does the system have to do the workaround?

    Thanks!

  • I have had this same issue. We are doing 1000+ items on some of ours, so the bug appears quite frequently.

    Found a fix. In the woocommerce-bulk-discount.php (line 151):
    return ( get_option( 'woocommerce_t4m_discount_type', '' ) == 'flat' ) ? max( 0, $d[0] ) : min( 1.0, max( 0, ( 100.0 - round( $d[0], 10 ) ) / 100.0 ) );

    When rounding, I changed the code to round at the 10th place, rather than 2. This fixed the bug for me.

    You also need to ensure that your discounts go to as many decimal points as possible. I presume you have discounts with repeating decimal points if you are receiving this error.

    Tried it, and no luck, unfortunately. Even if I change my discount price to match the one generated by Bulk Discounts, it’s always a little off.

    Thanks for the tip, though!
