Fulfillment cost in Mexico: how to calculate what each order really costs you
Anyone searching for fulfillment cost is usually already evaluating a provider. The problem is that every operator prices differently, and comparing “price per order” without understanding the line items leads to surprises. Here’s what really makes up the cost.
The line items of fulfillment cost
A fulfillment cost is built from several pieces:
- Receiving: receiving and inspecting incoming merchandise.
- Warehousing: the space your inventory takes up (by location or volume).
- Picking: picking each item of the order.
- Packing: material and labor to pack.
- Labeling / marketplace prep: meeting each channel’s requirements.
- Shipping: the carrier rate by weight, zone and dimensions.
- Returns (reverse logistics): receiving, checking and restocking product.
- Special services: kitting, assemblies, value-added.
How storage is charged: pallet, square meter, cubic meter or unit
| Billing unit | How it works | When it suits you |
|---|---|---|
| Per pallet per month | You pay for each pallet position you occupy. | Product in cartons that stacks; the most common in Mexico. |
| Per square meter | You pay for floor area, used vertically or not. | Product that does not go on racks, or dedicated space. |
| Per cubic meter | You pay for the volume occupied. | Bulky, light or irregular product. |
| Per unit or small location | You pay per item or per shelf. | Many SKUs of small items, typical of e-commerce. |
To work out how many pallets your inventory takes, use the pallet calculator.
An example for a B2B operation with pallets
Almost every example out there is for an online store. This one is for a brand that supplies stores and DCs. The volumes are illustrative; what matters is which lines appear on the quote.
| Line | What is counted in a month | How it is usually charged |
|---|---|---|
| Receiving | 2 containers | Per container or per pallet received |
| Storage | 120 pallets on average, 180 in peak season | Per pallet per month |
| Outbound prep | 300 pallets built for stores and DCs | Per pallet or per carton picked |
| Retailer labeling | 6,000 cartons | Per unit |
| Loading and freight | 40 shipments | Per shipment, by destination and vehicle type |
Ask for every line separately: that way you can compare providers and see which line grows when your volume grows.
Minimums, VAT and what the rate card hides
- Monthly minimum. Some Guadalajara providers publish a minimum of MXN 8,000 to 10,000 + VAT per month, even if you use less; we compare them in 3PL companies in Guadalajara. Vorago OPS has no minimum billing or contract.
- VAT. Check whether the rate includes it; for B2B services it is almost always separate.
- Billing period. Paying for a full month is not the same as paying per month or fraction when inventory leaves early.
- Packaging material. Boxes, fill and tape may be included or charged per order.
- Returns. Ask whether they are charged as a normal receipt or at their own rate.
How to compare two quotes
- Both use the same storage unit, or convert them to pallets.
- They split receiving, storage, prep, material, shipping and returns.
- They state whether there is a monthly minimum and when billing starts.
- They include the indicators the service is measured by: inventory and picking accuracy, and on-time delivery.
- You can tour the warehouse before signing.
The cost almost no one adds: operational error
On top of the rates, you must add the cost of errors: a wrong shipment costs the reship, the lost product, the negative review and, often, the customer. That’s why picking accuracy isn’t a luxury: it’s part of the real cost.
How to estimate your cost per order
A simple way: add the monthly cost of all line items (warehousing + operation + shipping + returns) and divide by the number of orders that month. Compare that against what it costs you today to operate in-house —including rent, staff, software and errors— and you’ll have an honest comparison, not just “rate vs. rate”.
A simplified example
If in one month you pay warehousing, picking and packing, shipping and some returns, and divide it by your orders for the month, you get your outsourced cost per order. The 3PL advantage is that this cost is variable: sell less, pay less; sell more, scale without hiring.
