Hey there,

$18,000 per year saved.

Same product. Same quality. Same customer experience (mostly). Just smarter packaging.

This is the story of a DTC home goods brand that cut $18K in annual costs through four packaging changes — none of which their customers noticed.

It's the perfect finale for Hidden Margin Killers Month because it brings together everything we've covered: DIM weight, fulfillment fees, the hidden cost audit. This case study is what happens when you apply all of it to one product line.

Let me walk you through exactly what we did.

Before I dive into the case study — this is exactly the kind of work we do in The Hidden Margin Killers: A Cost Engineering Workshop.

If you've been following along this month and thinking "I need to actually implement this stuff" — the workshop is your implementation path.

COGS is just the beginning. Beyond the purchase order lies a landscape of costs most founders never audit. Packaging materials. Labeling fees. Prep charges. DIM surcharges. Return processing. Quality failures. Customer service load per SKU.

This workshop is a systematic hunt. We go line by line through your 3PL invoice, your packaging specs, your freight bills — and I show you exactly which costs are large enough to matter and how to fix them.

What you'll learn:

→ The hidden cost landscape for DTC brands — where to look, what to measure, and which costs actually move the needle

→ The DIM weight problem explained: how to audit packaging for dimensional efficiency and calculate redesign ROI

→ A fulfillment cost audit checklist: what each fee means, what's normal, what's excessive, and how to push back

→ Case study: This exact $18K packaging redesign — step by step, with the templates I used

This is for founders who know their margins are too thin but don't know where the leaks are.

$1.8M annual revenue. DTC home goods — think kitchen and dining products. Nice margins on paper, but the founder felt like money was leaking somewhere.

She was right.

42,000 orders per year. Average order value around $43. Product cost was dialed in. But "shipping and fulfillment" was this black box line item that kept growing.

When we dug in, we found her packaging hadn't been reviewed since she launched three years earlier. Same boxes. Same inserts. Same everything — designed when she was doing 200 orders/month and "good enough" was the standard.

At 42,000 orders/year, "good enough" was costing her $18K annually.

Here's what we changed.

The Problem:

Her primary shipping box was 14" × 11" × 9". The product inside? 10" × 8" × 5" with padding.

That's 4 inches of empty space in one dimension, 3 in another, 4 in the third. Air on all sides.

The box existed because three years ago, her supplier only offered that size and she didn't want to pay for custom. Totally reasonable at launch. Totally expensive at scale.

The Math:

→ Old box: (14 × 11 × 9) ÷ 139 = 9.9 lbs DIM weight (rounded to 10 lbs billable)

→ Product actual weight: 2.1 lbs

→ She was paying for 10 lbs on a 2.1 lb product

The Fix:

We worked with a packaging supplier to design a right-sized box: 11" × 9" × 6".

→ New box: (11 × 9 × 6) ÷ 139 = 4.3 lbs DIM weight (rounded to 5 lbs billable)

→ Weight reduction: 10 lbs → 5 lbs billable

→ Savings per shipment: ~$0.52

→ Annual shipments using this box: ~15,800

→ Annual savings: $8,216

Cost to redesign: $1,200 (design + first order of custom boxes).

Paid for itself in 7 weeks.

The Problem:

Every order shipped with:

→ Branded tissue paper (2 sheets)

→ A thank-you card

→ A product care instruction card

→ A discount code card for next purchase

→ A brand story booklet (4 pages)

Total insert cost: $1.87 per order.

Here's what we learned when we actually talked to customers: Nobody read the brand story booklet. The tissue paper went straight in the trash. The discount code had a 2% redemption rate.

The only things customers kept? The thank-you card (personal touch) and the care instructions (functional need).

The Fix:

→ Eliminated tissue paper (nobody missed it)

→ Combined thank-you card, care instructions, and discount code onto one double-sided card

→ Eliminated the brand story booklet (moved to email post-purchase sequence)

New insert cost: $0.89 per order.

→ Savings per order: $0.98

→ Annual orders: 42,000

→ Annual savings: $4,116

Cost to implement: $400 (new card design + print run).

And here's the kicker: NPS score didn't change. Customers didn't notice or care. The "unboxing experience" they valued was the product itself, not the tissue paper.

I recorded a YouTube video showing exactly how to run a packaging audit like this one — including the spreadsheet I use to calculate DIM weight savings, insert cost analysis, and ROI on redesigns.

I walk through this exact case study with the actual numbers and show you how to apply the same framework to your packaging.

The Problem:

Her 3PL was charging $0.45 per unit for "prep" — which included receiving, labeling, and putting away inventory.

When we audited it, we found two issues:

First, $0.45 was above benchmark for her volume (should have been $0.32-$0.38).

Second, "labeling" was part of the fee — but her products arrived from the supplier pre-labeled. The 3PL was charging for a service they weren't performing.

The Fix:

She scheduled a call with her 3PL account manager. Came with the data:

"I'm being charged for labeling, but my products arrive pre-labeled. I'm also paying above benchmark for my volume. Here's what I'm asking for: $0.37 per unit, no labeling component."

The 3PL pushed back initially. She held firm. They settled at $0.37.

→ Old rate: $0.45/unit

→ New rate: $0.37/unit

→ Savings per unit: $0.08

→ Annual units: ~42,000

→ Annual savings: $3,360

Cost to implement: $0. Just a conversation.

This is what I mean when I say the money is hiding in fees you've never questioned. She'd been paying for labeling that wasn't happening for two years.

The Problem:

Her return rate was 11% — not terrible for home goods, but not great. Return processing cost: $4.50 per return.

When we dug into the returns data, we found that 40% of returns were "item not as described" or "wrong size/fit." Not product defects — expectation mismatches.

The product photos on her site were beautiful but didn't show scale. Customers were surprised when items arrived smaller (or larger) than expected.

The Fix:

Two changes:

1. Product photography update: Added scale reference images (products shown next to common objects, hands holding items, items in context).

2. Renegotiated return processing fee: Her 3PL was charging $4.50 for full inspection + restocking. But 60% of her returns were sellable with minimal inspection. She negotiated a tiered rate: $3.25 for standard returns, $5.00 only for items requiring full QC.

Results:

→ Return rate dropped from 11% to 8.5% (better photos reduced "not as described" returns)

→ Average return processing cost dropped from $4.50 to $3.25

→ Annual savings: $2,328

Cost to implement: $1,200 (new product photography).

Four changes. One product line. One quarter of implementation.

→ Box redesign: $8,200/year

→ Insert simplification: $4,100/year

→ Prep fee renegotiation: $3,400/year

→ Returns optimization: $2,300/year

Total annual savings: $18,000

Total implementation cost: $2,800

ROI: 6.4x in year one. Every year after that is pure margin.

Same product. Same quality. Same (or better) customer experience. $18K back to the business.

One thing I want to highlight: we didn't cut anything sacred.

Before making any changes, I sat down with the founder and asked: "What's sacred and what's negotiable?"

Here's how we categorized everything:

Tissue paper customers threw away immediately? Negotiable. Gone.

Insert messaging they actually kept? Sacred content, negotiable format. Kept the message, consolidated the cards.

Box protection that prevents damage? Sacred. Didn't compromise on protection, just eliminated empty space.

Extra air space "for premium feel"? Negotiable. Nobody feels premium about air. They feel premium about the product.

This framing is critical. Packaging optimization isn't about cutting corners. It's about finding the things that don't create value and eliminating them — so you can invest in things that do.

The $18K she saved? Part of it went into better product photography. Part into email marketing. Part into faster shipping for VIP customers. She reinvested the savings into things that actually moved the needle.

This wraps up April. Here's what we covered:

Week 1: The costs that don't show up on your PO — mapped the hidden cost landscape

Week 2: The DIM weight problem — stopped paying for air

Week 3: The 3PL fee audit — questioned every line item

Week 4: The $18K packaging redesign — put it all together

If you did the work — if you ran the audits, calculated the gaps, had the conversations — you've probably already found money. Reply and tell me what you discovered. I read every response.

If you haven't done the work yet, the newsletters aren't going anywhere. Go back. Start with Week 1. The frameworks are all there.

If you've been following Hidden Margin Killers Month and thinking "I want help implementing this on my business" — that's exactly what the Accelerator is for.

The Supply Chain Accelerator is a 12-week program where we build your supply chain systems together. Not theory. Actual implementation — including full packaging audits, 3PL negotiations, and cost engineering.

What you get:

→ All 11 modules (including the complete Hidden Cost Audit framework with every template from this month)

→ Weekly live calls with me — bring your invoices, your packaging specs, your stuck points

→ Direct Slack access for async support

→ Hot seat coaching where I review your actual numbers

→ Community of 9 other founders at your stage

That $18K brand from today's case study? She was in Cohort 4. We did the packaging audit together on a hot seat call. Three months later, all four changes were implemented.

Q2 Cohort starts in May. If you're doing $200K-$3M in revenue and want to stop leaving money on the table, this is your path.

Not ready for the full cohort? Self-paced is $500 — same modules, same templates. Just without the live calls and direct access.

Next month, we're tackling the question I get asked more than any other:

Domestic vs. overseas. When does it make sense to move? When should you stay?

We'll cover the real math (not the vibes), the hidden costs of switching, and the scenarios where each option actually wins.

See you in May.

Until next time,

Lara

P.S. The best packaging optimization projects start with one question: "When was the last time we actually reviewed this?" If the answer is "when we launched" or "I don't know" — you've got money waiting to be found.

P.P.S. $18K might not sound like a lot on a $1.8M business. It's 1% of revenue. But here's the thing: it's pure margin. At a 30% net margin, that $18K would require $60K in new revenue to achieve the same bottom-line impact. Which is easier — finding $60K in new sales or fixing a box?
