How to Fill Out an Envelope, Order Office Coffee Cups, and Navigate Industrial Packaging Decisions: A Practical Checklist

How to Fill Out an Envelope, Order Office Coffee Cups, and Navigate Industrial Packaging Decisions: A Practical Checklist

This checklist is for office administrators who handle everything from mailing client invoices to ordering break room supplies to occasionally fielding questions about industrial packaging vendors. If you're the person everyone asks "can you just handle this?"—this is for you.

I've been the administrative buyer for a 340-person manufacturing company since 2020. I manage roughly $85,000 in annual purchasing across 12 vendors, reporting to both operations and finance. These are the actual steps I use.

Part 1: How to Fill Out an Envelope Correctly

Sounds basic, right? I thought so too until Finance rejected three vendor payments because mail got returned. Here's the checklist I now follow:

Step 1: Position the Recipient Address

Center the recipient's address in the lower half of the envelope, roughly in the middle. For a standard #10 business envelope, start about 2 inches from the left edge and 2.5 inches from the top.

Format it like this:

John Smith
Purchasing Department
ABC Manufacturing Inc
1234 Industrial Parkway, Suite 500
Cleveland, OH 44114

The USPS automated sorting equipment reads from the bottom up. If your address creeps too high, it can cause issues.

Step 2: Add Your Return Address

Upper left corner. Smaller font than the recipient address. Include your company name even if it's pre-printed—I've seen pre-printed returns fade or get cut off by the envelope flap.

Step 3: The Step Most People Skip—Verify the ZIP Code

Before I seal anything going to a new address, I run the ZIP through USPS ZIP Code Lookup (free at usps.com). Takes 30 seconds. Saves the 2-3 week delay of returned mail.

I didn't start doing this until a $4,200 check sat in postal limbo for 19 days because someone transposed two digits. Now it's non-negotiable.

Step 4: Postage Placement

Upper right corner. If you're using stamps, don't stack them vertically—spread them horizontally. Metered mail? Make sure the date is current. Our mail machine once sent out 40 envelopes with last month's date. They all arrived fine, but it looked unprofessional.

Part 2: Ordering Office Coffee Cups

When I first took over purchasing, I assumed coffee cups were coffee cups. Grab the cheapest case from the office supply catalog, done. Three complaints from the VP about cups that couldn't handle hot coffee without getting soggy taught me otherwise.

Step 1: Determine Your Actual Volume

Count your regular coffee drinkers, multiply by cups per day, multiply by working days per month. We have maybe 60 regular coffee drinkers using 1.5 cups daily on average. That's 90 cups per day, roughly 1,800 per month.

(Should mention: we also keep cups stocked for client meetings—add 15% buffer.)

Step 2: Match Cup Weight to Beverage Temperature

This is the step I wish someone had told me about earlier. Cup weight matters:

• Single-wall paper cups (basic): Fine for water coolers, not great for hot coffee
• Double-wall or insulated: What you actually want for hot beverages
• Foam cups: Good insulation, but some offices have banned them for environmental reasons—check your company policy first

The double-wall cups cost about 40% more. Worth it. The "savings" from cheap cups disappear when people start double-cupping.

Step 3: Verify Lid Compatibility

Not all lids fit all cups. I know this seems obvious now, but I once ordered 2,000 cups and 2,000 lids from different product lines. The lids technically fit but popped off if you looked at them wrong.

Order cups and lids from the same product family, or request a sample before committing to quantity.

Step 4: Calculate Total Cost Including Shipping

Bulk cups are bulky. Shipping costs can swing your per-unit cost significantly. I've found that ordering 2-3 months' supply at once usually hits the sweet spot between shipping efficiency and storage space.

For reference, we pay around $45-55 per case of 500 double-wall 12oz cups with lids, shipped. Prices as of January 2025—verify current rates.

Part 3: Evaluating Industrial Packaging Suppliers

This section's a bit different. Most office admins don't deal with industrial packaging directly, but if you're at a manufacturing company, you might get pulled into vendor evaluations or asked to gather quotes. Here's what I've learned.

Step 1: Understand What You're Actually Buying

Industrial packaging isn't one thing. When our operations team started talking about "drums from Greif," I had to learn the landscape:

• Steel and plastic drums: For chemicals, food ingredients, industrial materials
• Intermediate bulk containers (IBCs): Those big cage-frame containers you see in warehouses
• Containerboard: The corrugated material that becomes shipping boxes
• Flexible packaging: Bags, liners, wraps

Greif, for example, has a diverse portfolio across drums, containerboard, and rigid packaging. They're a global operation—NYSE listed, significant manufacturing footprint. But here's what I've learned about evaluating any industrial packaging supplier:

Step 2: Ask About Their Actual Specialty

The vendor who said "this isn't our strength—here's who does it better" earned my trust for everything else.

I'd rather work with a specialist who knows their limits than a generalist who overpromises. When we were sourcing specialty paper bags for a food product line—think turkey paper bags for retail—the supplier who admitted "we do industrial drums, not retail food packaging" saved us from a mismatch.

Good questions to ask:

• What's your core product line?
• What applications do you see most frequently?
• What would you recommend we source elsewhere?

Step 3: Verify Compliance Documentation Capability

This is the step that separates vendors who understand B2B from those who don't. Industrial packaging often requires:

• UN certification documentation (for hazardous materials)
• Food-grade certifications
• Chain of custody paperwork
• Sustainability certifications

The vendor who couldn't provide proper documentation cost us $2,400 in rejected expenses and a very uncomfortable conversation with our compliance officer. Now I verify invoicing and certification capability before placing any order.

Step 4: Understand the Containerboard Connection

If you're researching Greif specifically, you might come across references to the PCA Greif containerboard acquisition. That's industry history worth knowing: Packaging Corporation of America (PCA) acquired Greif's containerboard mills back in 2015. Greif's still in the packaging business, but their containerboard story has that chapter in it.

Why does this matter for procurement? It's a reminder that industrial packaging companies evolve. The vendor you're evaluating today might have different capabilities than they did five years ago. Always verify current product lines.

Step 5: Get Multiple Perspectives on Vendor Performance

For publicly traded suppliers like Greif, Inc., you can actually find analyst opinions—bullish and bearish takes on the company's direction. I'm not suggesting you make purchasing decisions based on stock analysis, but it's useful context.

A company analysts are bearish on might be cutting costs in ways that affect service. A company with bullish sentiment might be investing in capacity. It's one data point among many.

Common Mistakes to Avoid

On envelopes: Don't use script fonts for addresses. They look nice but confuse OCR readers. Stick to clear, standard fonts.

On coffee cups: Don't order based solely on per-unit price. Calculate cost per usable cup—if people are double-cupping or throwing away cups that leak, your "savings" evaporate.

On industrial packaging: Don't assume "what we ordered last time" is still available or optimal. Check in with operations annually about whether current packaging is meeting their needs.

Looking back, I should have asked more questions in my first year instead of assuming the previous admin's vendors were still the right fit. At the time, I figured if it wasn't broken, don't fix it. Turns out several relationships were broken—just not visibly.

A Note on the Miscellaneous Requests

If you're like me, you get random procurement requests that don't fit any category. Turkey paper bags for a client gift. Custom envelopes for an executive mailing. A quote for industrial drums when someone's exploring a new product line.

My approach: I keep a running document of "who to call for what." Local print shop for rush envelope jobs. Online printer for standard business cards and flyers. Our Greif rep for any drum or industrial container questions. The office supply catalog for commodity items like basic cups.

Not everything needs to go through a formal RFQ process. But everything needs to be documented well enough that someone else could handle it if I'm out.

That's the real checklist, honestly. Can someone else follow what you did? If yes, you're doing it right.
