For e-commerce sellers

Supply for fulfillment centers

Custom-printed mailers, specialty packaging, jan-san for the warehouse, PPE for the fulfillment crew, light MRO, branded shipping consumables. One quote across categories. Ship to your fulfillment center. No procurement bureaucracy. Built for Shopify / TikTok Shop / Amazon FBA brands at $1-25M revenue.

The problem

Founder-led brands run 3-5 vendors for everything that is not their main packaging.

A growing e-commerce brand at $1-25M revenue running its own fulfillment center burns founder time on operational supply procurement. Uline for stocked boxes. A custom-print shop for branded mailers. Amazon Business for jan-san. Costco runs for breakroom. Best Buy for that one printer toner. Most operators do not have a procurement person; the ops lead or the founder is running point.

Multi-vendor friction at sub-$10M scale.

You are not big enough for direct manufacturer contracts (Pratt / Smurfit / Sealed Air won't talk to you until you do truckload volume). You are too big for Costco runs to make sense. The middle is where multi-vendor friction lives, and most brands stay in it for years because switching costs feel real.

Custom-print lead times surprise founders.

Specifying custom-printed mailers, branded tissue, custom-printed boxes requires 2-4 week first-run lead times. Most operators discover this when they realize they need new packaging the week before a launch. Then they ship in blank boxes and lose the branded-unboxing experience that justified the custom-print decision.

Q4 ramp breaks the standing-order cadence.

September monthly order: 8 cases of mailers. October: 14 cases. November: 28 cases. December: 12 cases. Standing PO at constant volume is wrong for 4 months of the year, and most distributors are not staffed to handle the spike. Stockouts in November cost real revenue.

Non-packaging supply gets ignored.

Founder optimizes packaging because shipping margin is visible. Jan-san for the warehouse, safety / PPE for the picking crew, light MRO, office for the back-office, IT consumables all get bought ad-hoc on Amazon Business at retail markup. Aggregate is real money: $30-80K / year on a $5M brand.

FAQ

Questions from e-commerce founders.

How are you different from Uline?

Uline is great when you know exactly what stocked SKU you want and you want it tomorrow. Where we differ: multi-vendor sourcing in one quote (custom mailers + stock corrugated + jan-san in one quote, one invoice), file-format flexibility (Excel, photo, plain text), and bundling across categories Uline does not carry deep (specialty packaging, ESD, food-grade, hazmat). For commodity stocked items where Uline excels, Uline often wins.

What about my existing packaging volume contract?

Keep it. If you have a direct contract with Pratt / Smurfit / Sealed Air at truckload pricing, we work alongside, not against. We cover what your packaging contract doesn't: custom-printed, specialty, jan-san, safety, light MRO, office. Most e-commerce customers use us for 30-50% of operational supply, not 100%.

Do you supply custom-printed mailers and branded packaging?

Yes. Custom-printed poly mailers (1-4 color flexo, or digital for short runs), branded tissue, custom-printed tape + thank-you cards + kraft mailers + corrugated boxes. 2-4 week first-run lead, faster on repeat.

Can you handle Q4 holiday ramp burst?

Yes. Standing PO + override mechanism so Q3 / Q4 burst routes separate from monthly cadence. September forecast lock gets you priority allocation when Oct-Nov demand spikes.

ESD / static-dissipative packaging for electronics?

Yes. Static shielding bags, anti-static polybags, pink anti-static foam, ESD-safe corrugated, conductive containers, ground-strap kits.

Do you supply hazmat-compliant packaging?

Yes. UN-certified 4G fiberboard, 4GV combinations, hazmat labels + placards, lithium-battery-compliant packaging. Required for chemical, lithium battery, biological, paint shipping.

Credit card or net-30?

Credit card on first order = no credit review, place in minutes. Net-30 on subsequent orders after a 3-7 day credit review.

I am a 3-person team with no procurement person. How does this work?

That is most of our e-commerce customers. Founder or ops lead emails quote@cintrasupply.com with a list (any format). We reply in minutes. You approve, we ship. No portal, no procurement bureaucracy.
