Operations: fulfilment, packaging & compliance
MCF moves boxes. A business order is a commercial transaction with documents attached, and the documents are the part MCF has no opinion about. It will happily deliver units to a shop, a clinic, a school or a distributor's office. It will not put a purchase order number on the packing slip, will not issue an invoice, will not hold a payment term, and will not know that your customer is tax exempt.
For a brand running wholesale orders through its own portal or a Shopify business channel, that is workable — as long as you know which half of the job you still own.
What a business order needs that a consumer order does not
Sit with a typical business order for a moment, because the differences are not cosmetic.
A business buyer orders against a purchase order number issued by their own system, and they expect that number to appear on the packing slip, the invoice and any correspondence. Their accounts payable will not pay an invoice they cannot match to a PO.
They buy on terms. Card at checkout happens with small independents, but the moment you are dealing with a clinic, a school district, a hotel group or a distributor, the expectation is net terms from delivery or from invoice date.
They are often exempt from sales tax on goods they intend to resell, and they prove it with a resale certificate. Once you hold a valid certificate for that customer in that state, you should not be charging tax on their orders, and you need to keep the certificate on file because it is your evidence if the state ever asks.
They want a proper invoice: your legal entity, their bill-to address, the PO number, line items, unit prices, quantity shipped, terms, and a due date.
And they want to know when it will arrive within a window, because somebody has to be there to receive it.
What MCF handles
The physical half, and it handles it well.
Units come out of your existing FBA stock, so there is no second inventory pool to manage and no minimum order. You can pick a delivery speed, and the slower ones cost less, which suits business orders where nobody needs it tomorrow. Unbranded packaging is available, so the box does not advertise the marketplace to your trade customer.
If your wholesale portal runs on a platform with an MCF connector, orders can flow through without anyone re-keying them. That is the genuinely good version of this setup: the buyer places a business order on your site, your platform issues the order confirmation and the invoice, and MCF quietly ships the goods.
What you still have to build
Everything with a signature on it.
The order document. Whatever system takes the order — your store's wholesale channel, a spreadsheet, an emailed order form — has to capture and store the PO number and echo it back on your paperwork. MCF will not carry it.
The invoice. You issue it, you number it, you send it, you chase it. If you have been selling to business customers on the marketplace instead, the contrast is worth reading in Amazon Business invoices, where the platform does this part for you.
Terms and collections. Deciding who gets net thirty, on what credit check, with what limit, is a policy you write. So is what happens on day forty-five. Amazon's own payout rhythm has trained most sellers to expect money quickly; the difference is set out in Amazon payout vs net 30.
Tax. You collect and validate resale certificates, store them, and configure your tax engine so exempt customers are not charged. Getting this wrong in either direction is expensive: charge tax you should not have and the customer deducts it from the invoice; fail to collect tax where no valid certificate exists and the liability is yours.
Delivery expectations. If the ship-to is a location with a receiving window, you communicate it, because MCF will not arrange an appointment.
Where MCF quietly fails a B2B order
Three failure modes worth naming before they happen to you.
The first is packaging identity. Units come out of FBA in the state Amazon holds them, which usually means a poly bag and an FNSKU label. A shop that puts your product straight on a shelf now has a barcode that is not the one their till expects, and a mis-scan at the register is the kind of small irritation that ends a stocking relationship. What the two barcode systems are actually for is explained in UPC codes for retail vs Amazon.
The second is case integrity. Business buyers order in cases and count in cases. MCF picks eaches and boxes them however it likes. If your order confirmation says four cases of twelve and eleven parcels arrive, your customer's receiving record disagrees with your invoice, and that dispute takes longer to resolve than the order was worth.
The third is inventory contention. An MCF order consumes the same units your listings sell. A single large business order taken out of FBA can drop your cover below the level where Amazon starts charging for low inventory, and can push a good-selling ASIN towards a stockout. Whether to keep business orders out of that pool entirely is the core question in inventory split between Amazon and wholesale.
Should you use MCF or Amazon Business instead
These are different answers to the same demand, and it is worth being deliberate.
| MCF from your own portal | Selling through Amazon Business | |
|---|---|---|
| Who owns the customer | You | Amazon |
| Invoice and PO number | You issue | Platform issues |
| Terms | Your policy, your risk | Platform programme |
| Tax exemption | You validate and store | Platform handles |
| Fees | Fulfilment fee per unit | Referral fee plus fulfilment |
| Pricing control | Full | Quantity discount tools |
Selling to business buyers on the marketplace removes almost all the paperwork and hands you a customer you do not really own. Running your own portal with MCF behind it keeps the relationship, the data and the pricing, and gives you the administrative work. Most brands end up doing both for a while, which is fine as long as the prices are coherent across them.
When to move the B2B orders off MCF
The trigger is not volume, it is repetition. One business order a month through MCF is cheaper than any warehouse. Ten a month with the same customers reordering is a channel, and a channel deserves proper case packs, proper barcodes and a warehouse that can build them.
Two other triggers force the move regardless of volume. A customer asks for a case pack with a carton label, or a customer sends a vendor manual. Both are covered in wholesale fulfillment for Amazon sellers, and neither is possible from FBA stock.
Until then, the discipline that keeps MCF viable is pricing that includes the per-unit fulfilment cost honestly, rather than quoting a case price built on warehouse economics you do not yet have.
Getting the demand before the operations
All of this presumes business buyers exist for your product. Before building a portal, a tax workflow and a terms policy, it is worth confirming that the category has trade buyers at all — some products sell brilliantly to consumers and have no natural trade channel.
Paste your listing into WholesalePilot and the preview shows which distributors and retailers stock products like yours. If the list is thin, the answer may be that your growth is on the marketplace and the operations spend belongs elsewhere. If it is full, the order to build in is simple: capture the PO number, issue a real invoice, validate the tax exemption, and let MCF move the boxes until the cases get big enough to need a warehouse.
