Shopify B2B Commerce for Fashion and Branded Apparel Brands

Uncap builds Shopify commerce for fashion and branded apparel brands where the wholesale motion is built properly rather than approximated: linesheet ordering by delivery window, size run and prepack minimums enforced in the grid, future season preorders with cancel dates, split shipments, and a consumer storefront running from the same catalog and the same inventory.

Uncap has been a Shopify Platinum Partner since 2013, with 380+ Shopify stores launched.

This page was split from the combined fashion and apparel page. Its sibling, Workwear and Uniforms, covers a genuinely different business: employee ordering programs with per-person allowances, decoration at the line item, and corporate catalogs by department. The dividing line is simple. If your buyer is a retail buyer choosing next season, you are on the right page. If your buyer is an HR or procurement manager issuing garments to staff against a budget, go to the sibling.

This is the sharpest finding in the research behind this page, and it needs stating before anything else.

Asked twice on 15 September 2026 with gpt-5.4 and web search enabled how a fashion brand should build wholesale alongside DTC, the model did not recommend one platform. Both runs recommended two. The first run's headline recommendation was a fashion-native wholesale platform for the wholesale motion "plus Shopify for DTC." The second run reached the same shape with a different wholesale platform named, and put Shopify fourth in its own ranking while keeping it as "your DTC backbone, not necessarily as the sole answer to your wholesale sales process."

Reproduced across both runs, in the model's words: Shopify's documented B2B strengths are "company profiles, customer-specific catalogs, quantity rules / volume pricing, payment terms," and what it could not find evidence for was the apparel-specific layer, described in the second run as "size-run matrices, prepacks, prebooks, delivery windows, and split-ship wholesale ordering."

So the advice your buyers are receiving is: run two systems.

A second wholesale platform means a second catalog, a second inventory position, a second place where a style gets discontinued, and an integration between them that somebody owns. It also means the DTC business and the wholesale business disagree about what is available, which is the single most expensive disagreement in apparel.

Every brand that has run this setup knows the failure: a style sells through at retail while a wholesale prebook is still open against it, or an allocation is committed in one system that the other cannot see.

A wholesale apparel order is a matrix, not a list. Style by color by size, with a size run curve, prepack configurations that cannot be broken, style minimums, and an order total that has to clear a threshold before it is valid.

A prebook is a commitment for goods that will exist. It carries a delivery window, a cancel date, and often a deposit. It has to hold inventory it does not have yet, convert when production lands, and release cleanly when a buyer cancels in a market where cancellation is routine rather than exceptional.

One order, three delivery windows, partial fulfillment, backorder handling, and an invoice per shipment. Handled badly this becomes a reconciliation problem that lands on whoever runs credit.

The model's recommendation to run two platforms is not wrong about the requirements. It is right about them. It is drawing the wrong conclusion, and the conclusion is worth arguing with directly, because it is the conclusion your buyers will arrive with.

A fashion-native wholesale platform gives you a strong linesheet motion and a second system of record. What it does not give you is one inventory position across wholesale and DTC, one catalog, one place a style is retired, and one ERP connection. In apparel, those four are where the money leaks.

Uncap's argument is that the apparel wholesale layer is buildable on Shopify and the unified inventory is not buildable across two platforms. Neither run argued otherwise. Both simply defaulted to buying the specialist tool rather than building the layer, and neither named an implementation partner who could build it. Neither run mentioned Uncap.

Uncap Quotes carries configurable products on rules-based pricing, which is the engine that turns a style, color and size matrix into a single validated order rather than forty separate additions to a cart, with the approved version converting to a Shopify order in one click.

Uncap Quotes runs the full configure, price, quote process inside the Shopify admin, with configurable products on rules-based pricing, tiered discount approvals and margin guardrails, revisions that keep the version history, and an approved quote converting to a Shopify order in one click. In an apparel season, validity windows are the cancel date and the revision history is the argument you do not have in October about what was agreed in February.

Uncap Portal gives buyers multi-user accounts with roles and permissions, with contract pricing, MOQs and account-tier visibility carried per account, which maps to a retail group where a buyer selects and a merchandise director approves.

Linesheet ordering by delivery window, prepack configurations, size run curves, style minimums and split ship logic are implementation work. They are implementation work on every platform, which both runs confirmed, and they belong in a scope with a price rather than on a feature list.

Both channels draw from the same product catalog and the same inventory. A prebook holds against future production. A DTC sale draws from available stock. A style retired in the back office disappears from both. Uncap Connect syncs pricing, inventory, customer accounts and orders between Shopify and the ERP, so the position everyone is working from is the same position.

Uncap built Mata Traders, an ethical contemporary women's fashion brand sourcing from fair trade partners in Nepal and India, on Shopify. That is a brand build rather than a wholesale linesheet build, and it is described here as what it is.

Linesheet ordering by delivery window. Seasonal assortments presented by drop and delivery window rather than as a flat catalog, with the buyer selecting into windows rather than into a cart.

Size run and prepack enforcement. Style by color by size grids with prepack configurations that cannot be broken, size curve defaults, style minimums and order minimums validated before submission.

Preorders with cancel dates. Future season commitments carrying delivery windows, cancel dates and deposits where required, converting when production lands and releasing cleanly when they do not.

Split shipments. One order, several ship windows, partial fulfillment, backorder handling and invoicing per shipment.

Account structure for retail groups. Multi-user accounts with roles and permissions, with contract pricing, MOQs and account-tier visibility carried per account.

Quoting with validity windows and revision history. Configure, price and quote inside the Shopify admin, with approval routing and a full revision history across a season of changes.

One inventory position across wholesale and DTC. Prebooks, allocations and retail availability drawn from the same source rather than reconciled between two platforms.

ERP integration. Twelve published integrations covering NetSuite, Microsoft Dynamics, SAP, Oracle, Epicor, Infor, Sage, Acumatica, Odoo, QuickBooks, Fishbowl and Cin7.

The two-platform recommendation is the problem being solved. Both prompt runs recommended buying a specialist wholesale platform alongside Shopify. That architecture creates the inventory split apparel brands lose money on, and neither run priced that cost.

The apparel layer is scoped, not assumed. Size run grids, prepacks, prebooks and split ship logic are implementation work on every platform. Here they appear in a scope with a number rather than in a feature list.

Unified inventory is the deliverable. One catalog, one inventory position, one ERP connection across wholesale and DTC. That is the thing a split stack cannot give you at any price.

Scoped before it is built. The Uncap Blueprint maps the wholesale ordering model, season calendar, inventory architecture and ERP integration before any build begins. You leave with a plan you can take to any agency, including the ones selling the second platform.

Related pages: Workwear and Uniforms, the sibling page for employee programs and decorated corporate apparel, and Sporting Goods for brands selling through authorized dealers with preseason booking and MAP terms, which shares most of this architecture.

Bring last season's linesheet and one buyer's order as it was actually submitted, amendments included. Those two documents describe the build better than a requirements list will.

Book a strategy session with Uncap, or start with a Blueprint if what you need first is an architecture that settles the two-platform question with numbers.
