Connect Once, Reach Anyone: Why Your Next Trading Partner Should Take Days, Not Months

By Paul Butler Simpson & Aniello Sabatino, Transalis

• The Transalis Trading Network spans 15,000+ connections and trading partners, processes 30m+ transactions a year, and reaches 98% of the electronically-trading UK retail market.

Somewhere in your organisation, a new contract is waiting on a connection. The buyer has mandated EDI, the commercial team has signed, and everyone is now circling the same question: how long until we can actually trade? If the honest answer is “a few months,” that timeline isn’t a technical inevitability. It’s a symptom of how the connection is being built.

We’ll say plainly what two decades in this market has taught us. Onboarding a trading partner should be measured in days. The reason most businesses still measure it in months has nothing to do with the difficulty of moving an order from one system to another, and everything to do with treating every new partner as a fresh construction project.

Why does adding one trading partner still take months?

Because the prevailing model treats each trading relationship as a bespoke, point-to-point build: a fresh piece of custom integration wired directly between your system and theirs. Every retailer, marketplace and supplier becomes another line in an ever-growing tangle of connections, each with its own formats, rules and failure points.

We call it the spaghetti web, and the trouble is that each strand looks manageable on its own. Twenty strands later, your team is no longer running integrations. They’re maintaining them. A partner quietly changes a validation rule, dispatch notes stop registering, and a week disappears into untangling why.

The most expensive version of this is the temptation to build it all yourself inside the ERP: to assume that because a modern platform can technically hold an EDI connection, it should. It can, right up until the partner on the other end revises their specification. Then the build that was meant to save budget becomes a permanent maintenance loop, quietly pulling your best engineers off the work that actually grows the business.

What is a B2B integration network, and why does it change the maths?

A B2B integration network is a single, shared connection point that links your business to every trading partner already on it, rather than a separate custom link for each one. You connect once, and you reach everyone inside, without building anything new for the next relationship, or the hundredth.

That one distinction rewrites the economics of onboarding. In a point-to-point world, the time and cost of trading climbs in a straight line with every partner you add; growth is something your architecture has to survive. On a network, the opposite happens. Every new participant makes the network more valuable to everyone already connected. We call it A2A: Anyone-to-Anyone. The relationships you can reach grow exponentially while the connections you maintain stay at exactly one.

Think of it the way we do. We’ve spent two decades building the motorway, the Transalis Trading Network, and the point of a motorway is that you don’t lay fresh tarmac for every journey. You join it once and go anywhere it reaches. (Our favourite illustration: in Switzerland, where flat open land is scarce, stretches of motorway are engineered to double as air-force runways. Infrastructure built for one job quietly becomes infrastructure for many.) Today that network spans 15,000+ connections and trading partners, processes 30m+ transactions a year, and reaches 98% of the electronically-trading UK retail market. The odds are that your next trading partner is already on it.

Outcomes, not software

Here is the part that matters most to anyone responsible for the architecture: joining the network is not the same as buying another tool to run. Transalis is a managed outcomes provider for B2B integration, EDI, eInvoicing and marketplaces, which means we take ownership of the formats, the protocols and the constantly shifting message standards on your behalf.

You should never have to staff a team of in-house EDI specialists to keep trade flowing, and you certainly shouldn’t have to learn what sits underneath. We swallow that complexity entirely. When a partner changes a rule at their end, it’s our problem to absorb, not a fire drill for your engineers. Your architecture stays clean: one integration into your existing ERP through our proven Transalis OpenEDI™ foundation, and a single point of access to everything beyond it. That’s the whole idea behind a phrase we’ve used for years. It’s EDI Made Simple.

How do you actually reduce trading partner onboarding time?

You reduce it by changing what “onboarding” means. In the old model, onboarding is construction: mapping, coding and testing a brand-new link from scratch. On a network, onboarding is enablement: switching on a route to a partner who, in most cases, is already connected. Construction takes months. Enablement takes hours, days at most.

This isn’t theory. Brands like Argos, AS Watson and Superdrug came to us having outgrown chaotic, manual setups that leaned on large in-house EDI teams, and scaled from a single major retailer to thousands of trading partners and marketplaces, without adding a single head to their operations or IT departments. They didn’t get faster at building connections. They stopped building them.

And because the same connection carries every message type (orders, dispatch notes, invoices, forecasts, stock and sales data), the value keeps compounding long after go-live. Most providers behave like a digital postman: they drop the document and walk away. With Transalis DataTrack™, that flow stops being a silent stream of files landing in an archive and becomes total transaction visibility: live business intelligence you can actually run operations on.

The shift worth making

What we’re really arguing for is a change of mindset. Stop treating each new trading relationship as something to be engineered, and start treating trade as something you join. The businesses that win the next few years won’t be the ones with the biggest integration teams. They’ll be the ones who decided their architecture should get simpler as they grow, not more tangled.

Your next trading partner is waiting on a connection. It should take hours, days at most. If it’s taking months, that timeline is telling you something about your model, and there’s a better one.

The real cost of the old onboarding timeline

Independent research into UK businesses' EDI arrangements found that under the traditional onboarding model, the average wait to add a single UK-based trading partner was two months, stretching to three months when the partner traded internationally. Multiply that across a growing list of retailers, marketplaces and suppliers, and it becomes clear why in-house teams spend more time managing an onboarding queue than running the business that depends on it.

One partner onboarded in a week, not months

Beauty brand Space NK is a real-world example of enablement over construction. When it moved onto the Transalis network, the first trading partner was onboarded within a single week, with the rest of its network brought on quickly once that first connection had proved out. That single week, not month after month of mapping and testing, is what onboarding looks like once the network already carries the standards, formats and connections a new partner needs.
