B2B · multi-site, one backend
Mainstack B2B — a storefront for every customer
Run a tailored storefront for every wholesale customer — different pricing, a different look, even a different login for each buyer — all from a single backend. A thousand faces, one system.

If you run a wholesale business, you already know how much ease of use matters to your B2B customers. The buyer placing the order doesn't choose you for product quality or service alone — often they stay simply because you're the supplier who's easiest to order from.
They want a smooth experience: not endless phone calls, not digging through email threads for the latest version of a price list. Make ordering effortless, and you become very hard to replace.
The realistic options aren't great
Until now, the choices have been limited. The very largest customers will often mandate a PunchOut catalogue plugged into their procurement system — SAP Ariba, Coupa or similar — powerful, but costly and complex to set up and maintain. For every customer below that tier, you're left with two unappealing directions:
Option A — a bolt-on sync tool
A clunky, non-ecommerce custom sync build. Not cheap — and you end up living with a product catalogue that looks and feels like a spreadsheet.
Option B — multiple sites on a SaaS platform
Stand up several stores on an off-the-shelf platform — but the fees and the way they work mean you're charged per site. The more storefronts you add, the closer keeping inventory and pricing in sync drifts to unmaintainable.
Both also bill per storefront — so a site for every customer is unaffordable, and most suppliers cap out at one or two while everyone else stays on email, phone and spreadsheets. And they're built as data feeds, not commerce: no division-level logic for a customer whose departments each order different gear, and no enterprise sign-on. So when a large customer mandates single sign-on through their corporate identity, an off-the-shelf sync tool simply can't comply — and a flagship account is suddenly at risk.
And the hidden cost is the catalogue itself. In the clothing and uniform trades, one style in ten sizes and five colours is already fifty SKUs — tens of thousands across a full range. Bolt-on sync tools force that catalogue out of your accounting system and make you attach an image to every SKU by hand; it's the kind of job that can tie up two staff for months before you've sold a thing.
Neither is good enough. So we built a better way.
Cut through the jargon
What you actually need, underneath the jargon
"Catalogue sync", "punchout" and "EDI" all come down to one thing: keeping your ERP and your storefront in step. Treat that as real ecommerce — not a data feed — and the same connection lets you give every customer a modern storefront of their own: many fronts, one backend. If you've already paid handsomely for "catalogue sync" or an "ERP push" and ended up staring at a crude, ERP-grade interface, that's the gap — you were sold a data feed when what your business needed was commerce.
One backend. A storefront for anyone.
With Mainstack you can conjure up a different website the way a platform would — but without the per-site bill. Once the system is in place you can use it in all kinds of ways: you can even spin up a dedicated storefront for each salesperson or department, and use it to measure their performance.
Mainstack is built on Adobe Commerce, which supports multi-site natively, and then customised for your business. Between that enterprise-grade foundation and our own years of local customisation experience, even complex, bespoke requirements become possible.
"Tailored" isn't skin-deep
We model the buying experience around how each customer actually orders. A uniform program, for instance, can bind everything down to the individual employee:
- •Approved garment styles, colours and sizes per account
- •Embroidery as a logo or a name — with set pricing for each, multiple logos, and logo placement
- •Individual staff logins, with each employee's uniform allowance calculated and deducted at checkout
- •Delivery addresses and freight worked out automatically
Because every order is bound to the customer's own accounts and rules, you stop losing accounts when a buyer's purchasing manager moves on — the ordering lives in your system, not in their head. And for corporate or government buyers who are particular about ease of use, we can strip the interface back to a clean, guided workflow with nothing they don't need.
Built for enterprise and government buyers
For larger, security-conscious customers — national retailers, corporates and local government — we can go further:
- •Single sign-on — staff log in with their existing work identity (for example, Microsoft / Azure AD), with no extra password to manage.
- •Access controls — restrict a storefront to approved networks or domains to meet a customer's security requirements.
- •Allowances that match their policy — different uniform allowances per department, reset automatically each financial year.
- •Order-approval workflows — route a purchase to a nominated approver in the back office before it's placed.
What changes for your business
Stop paying to keep a site switched on
One build, then it's yours — no per-site fees and no five-figure annual sync subscription. Your only running cost is hosting, and you can stand up another customer's storefront whenever you win one.
Stop fixing other people's typos
Buyers order against their own rules — approved items, sizes, allowances, delivery — and orders flow straight to MYOB. No rekeying, no version-thirty spreadsheet, no transcription mistakes to chase down later.
Stop losing the account when the buyer leaves
When every person on a customer's team self-serves on a storefront built around them, the ordering lives in your system — not in one purchasing manager's head. When they move on, the account stays with you.
