What is a fulfillment company?
A fulfillment company is a logistics operator that receives your inventory, stores it, prepares each order, and ships it to your end customer for you. In practice, you sell and they handle the entire physical chain: from the moment your goods arrive at the warehouse to the moment the package reaches the buyer's door.
The term comes from order fulfillment — the act of completing an order. When an e-commerce brand grows, packing from home or a small warehouse stops working: errors pile up, shipments fall behind, and the owner ends up spending more time on logistics than on selling. That's when a fulfillment company takes over the operation.
What services a fulfillment company offers
It's not just "storing boxes." A serious fulfillment operation covers the full order cycle:
- Inventory receiving: unloading, counting, inspection, and registering your goods in the system. This is where missing units or damaged products get caught before they become your problem.
- Storage: your product is kept in controlled positions (racks, pallets, locations), with warehousing organized by SKU so it can be located fast.
- Pick & pack: when an order comes in, an operator picks the correct products and packs them with the right materials.
- Shipping: the label is generated, the most convenient carrier is assigned by zone and cost, and the package goes out same-day or next-day.
- Returns management: receiving returns, inspecting them, and restocking the product into inventory if it's in good condition.
- Value-added services: kitting (building bundles), labeling, promo assembly, and lot/expiry control for regulated products.
The key is that all of this happens with real-time visibility: you see your inventory, your orders, and your shipments from a dashboard, without having to request reports.
How fulfillment companies charge
This is the part that confuses people the most — and where the hidden costs live. The standard model breaks pricing into components, so you pay for what you actually use:
| Item | How it's charged | What it covers |
|---|---|---|
| Receiving | Per unit, carton, or pallet received | Unloading, counting, registering inventory |
| Storage | Per position/pallet or per m³, monthly | The space your product occupies |
| Pick | Per piece or order line | Pulling each product from the warehouse |
| Pack | Per order + packing materials | Assembling and packing the parcel |
| Shipping | Carrier cost (sometimes with a margin) | The freight to your customer |
| Value-added | Per task (kitting, labeling, photos) | Special services on demand |
Storage per position is the most common model: you pay a monthly rate for each pallet position or location your product occupies. The faster your inventory turns over, the less you pay in storage proportionally.
Red flags in pricing:
- Excessive monthly minimums that charge you even when you don't sell.
- Generic "handling" fees with no breakdown of what they include.
- Storage rates with no granularity (you're charged for a full block even if you use a little).
- Long exclusivity contracts with no clear exit clause.
The healthy model is variable: a reasonable base fee plus usage-based charges. That way your logistics cost scales with your sales, not ahead of them.
In-house fulfillment vs. a fulfillment company
Doing it yourself feels cheaper at first, but the math flips with volume. Here's what you actually compare:
Running it in-house:
- Pros: full control, no middleman, makes sense early on with few orders.
- Cons: fixed warehouse rent, payroll for packers, buying racks and materials, inventory software, and the invisible cost of your own time. During peaks you can't scale overnight.
Using a fulfillment company:
- Pros: you convert fixed costs into variable ones, scale without hiring, access carrier rates negotiated by volume, and reclaim your time to sell.
- Cons: you depend on a third party, there's an onboarding curve, and you need to choose well so you don't inherit their problems.
The deciding factor in Mexico is seasonal peaks. El Buen Fin, Hot Sale, and Christmas can triple your volume in a single week. An in-house operation drowns; a fulfillment company with staff and capacity absorbs the spike without you losing sales. The inflection point is usually between 300 and 500 orders per month, where the cost of operating in-house consistently exceeds the fulfillment fee.
Fulfillment vs. 3PL vs. courier: they're not the same
Three terms that get mixed up constantly:
- Courier: only moves the package from point A to point B. Estafeta, DHL, FedEx. They don't store your inventory or prepare orders — they just transport.
- Fulfillment company: receives, stores, prepares, and ships your e-commerce orders. Its focus is the individual order to the end consumer (B2C).
- 3PL (Third-Party Logistics): the broadest concept. It includes fulfillment, but can also cover importing, B2B distribution to retailers, freight transport, bulk storage, and cross-border logistics.
In practice, almost every serious fulfillment provider in Mexico is also a 3PL — because pure fulfillment rarely covers everything. If you sell online but also supply retailers or import from Asia, you need a 3PL in Guadalajara that handles it all under one roof.
How to choose a fulfillment company in Mexico
Beyond price, these are the criteria that matter:
- CEDIS location: what counts is the distance to your customers, not to you. A well-placed warehouse in the center-west covers much of the country in 24-48 hours. Check the locations and delivery times to Mexico City, Monterrey, and the Bajío.
- Integrations: it must connect natively with your store — Shopify, Mercado Libre, Amazon, WooCommerce, TikTok Shop. Without integration, you sync inventory by hand, and that's a time bomb.
- Measurable SLAs: demand concrete commitments. The competitive standard is same-day for orders before 2:00 PM, picking accuracy above 99.5%, and clear receiving and returns times.
- Traceability: real-time inventory, lot and expiry control if you handle regulated products (supplements, cosmetics, food), and a dashboard where you see everything without requesting reports.
- Minimums and contract: understand the monthly minimums and the exit clause. Your inventory is always yours; avoid contracts that hold it as payment collateral.
Ask for historical data, not promises, and for references from clients in your own industry.
Frequently asked questions
How many orders do I need to hire fulfillment?
From around 100-200 monthly orders it's already worth evaluating. The real inflection point is between 300 and 500 orders, where the cost of running it at home (rent, payroll, errors, your time) exceeds the fulfillment fee. If your product needs specialized handling — lot, expiry, labeling — it can pay off even at lower volume.
How much does fulfillment cost in Mexico?
There's no single rate because it's charged by components: receiving, storage per position, pick, pack, and shipping. The real cost depends on your volume, your product size, and how fast your inventory turns over. Always ask for a breakdown by item, not a closed "price per order" that hides fees.
Do I lose control of my inventory?
No. The product stays yours and, with a good operator, you get more visibility than running it at home: you see stock, orders, and shipments in real time from a dashboard. Control comes from data, not from keeping the boxes in your own warehouse.
Does a fulfillment company handle shipping to the United States?
Many do, especially those operating as cross-border 3PLs. This requires customs documentation and correct tariff classification, so verify that your provider has real experience in importing and exporting, not just domestic shipping.
