Break-even for the technology fee

$300 ÷ $0.15 = 2,000 orders a month

A per-order fee costs less than a flat one in months below the break-even point and more above it.

Orders a month	Quote A: account and tech fees per order	Quote B: account and tech fees per order	Quote A: total per order with postage	Quote B: total per order with postage	Quote A: fixed fees as a share of total per order
500	$550 ÷ 500 = $1.10	$0.50 + $0.15 = $0.65	$11.90	$11.45	9.2%
1,000	$550 ÷ 1,000 = $0.55	$0.25 + $0.15 = $0.40	$11.35	$11.20	4.8%
5,000	$550 ÷ 5,000 = $0.11	$0.05 + $0.15 = $0.20	$10.91	$11.00	1.0%

Each total adds $1.75 + $0.55 + $8.50 = $10.80 to the fees per order.

Marked-up postage or the 3PL's own shipping rates would change the totals, not the fees.
