ecommerce · every channel connected

eCommerce stack consulting, Australia

Renio helps operations-led businesses across Australia choose and architect the right eCommerce stack, from Shopify and Shopify Plus through to commercetools for larger, multi-channel operations. We design the storefront to connect to your ERP from day one, so orders, inventory and fulfilment stay in one live picture rather than a set of disconnected channels. Based in Sydney and Melbourne, we work architecture-first, because the platform choice and the integration behind it decide whether growth is smooth or painful.

The eCommerce stack, chosen for fit

An eCommerce stack is a business decision before it is a technology one. The platform sets the ceiling on what channels you can run, how cleanly they connect to your operations, and how much manual work every order creates behind the scenes. Renio helps operations-led businesses choose and architect that stack so the storefront is an extension of the operating core, not a separate system someone reconciles by hand. We work across Shopify and commercetools, and we recommend the fit before we build. The builds that go wrong are usually the ones that treated the storefront as a design project and left the operations to be solved afterwards.

Shopify and Shopify Plus

Shopify is the right answer for most product businesses: quick to launch, well supported, and, at the Plus tier, deep enough for high-volume, multi-store and international operations. Its B2B capability now runs wholesale ordering alongside the consumer store, which is often why a growing brand outgrows a simpler storefront. Where teams get into trouble is not the storefront, it is the connection behind it: Shopify running as an island, with orders and stock re-keyed into the ERP. We build Shopify so that it plugs into your operating core, with orders, fulfilments, inventory and pricing kept in one live picture.

commercetools and composable commerce

commercetools is a composable, MACH-based platform for larger operations whose requirements a packaged storefront cannot express cleanly: multiple front ends, complex catalogue and pricing logic, or multi-brand and multi-channel structures that need to be assembled from best-of-breed parts. Composable commerce buys real flexibility, and it costs real complexity. We help you judge whether your requirements actually use that flexibility, and we implement commercetools where they do.

Storefront to ERP architecture

The storefront and the ERP have to behave as one system. Orders placed online should appear in the operating core without re-keying, stock should reflect one live position across every channel, and fulfilment should flow back to the customer automatically. We design this from day one, integration-ready, so the stack grows by adding connected channels rather than adding manual work. The integration layer that makes this hold up under volume is core to what we do, and it usually sits around a NetSuite or other ERP core.

Replatforming without operational damage

Most replatforming pain is self-inflicted: the storefront is cut over before orders, inventory and fulfilment are proven against the new stack, and the ops team spends launch week firefighting. We do it in the opposite order. The ERP and integration layer are made stable first, the new platform runs alongside the old where that lowers risk, and the cutover happens channel by channel. A replatform done this way is one your customers and your operations team barely notice.

Multi-channel and marketplace architecture

Every channel you add multiplies the ways stock and orders can drift out of sync unless the architecture holds them together. We make the ERP the single source of truth and treat the webstore, marketplaces and physical channels as connected endpoints against it, so there is one live inventory position and no overselling one channel while stock sits idle for another. Done properly, adding the next channel is a connection, not a rebuild, and the data stays clean enough for AI operations to act on later.

Shopify or commercetools: which suits our business?

Shopify, including Shopify Plus, suits most product businesses: fast to launch, well supported, and deep enough for high-volume multi-store operations. commercetools is a composable, MACH-based platform for larger operations with complex, multi-channel or multi-brand requirements that a packaged storefront cannot express cleanly. Most businesses are better served by Shopify than they assume. We recommend based on your channels, catalogue complexity and roadmap, not on which platform is fashionable.

When is composable commerce worth it, and when is it over-engineering?

Composable is justified when you genuinely need to assemble the stack from best-of-breed parts: multiple front ends, unusual commerce logic, or channel and brand requirements that a monolithic platform forces you to fight. It is over-engineering when a well-configured Shopify Plus would do the same job at a fraction of the operational overhead. Composable buys flexibility and costs complexity, so it only pays off for businesses whose requirements actually use that flexibility. We will tell you which side of that line you sit on, and why.

How do you connect a storefront to our ERP?

We architect the storefront and the ERP to work as one operating picture, with orders, fulfilments, inventory and pricing flowing between them rather than being re-keyed. The storefront is designed integration-ready from day one, which is the difference between a stack that scales with new channels and one where every addition multiplies the manual work. The integration itself is core to what we do; see systems integration.

Can you replatform us without breaking operations?

Yes. The failure mode is cutting the storefront over before the operations behind it are proven. We stabilise the ERP and integration layer first, run old and new in parallel where that lowers risk, and cut over channel by channel. Customers should not notice the move, and neither should your ops team.

Will a replatform cost us our search rankings or order history?

Not if it is planned for. Two things quietly do the most damage in a replatform, and both are avoidable: losing organic search when URLs change without a redirect map, and losing history when orders, customers and subscriptions do not come across cleanly. We treat the redirect plan and the data migration as first-class parts of the cutover, not an afterthought. The rankings and the history are assets you have already paid for, and the point of doing this properly is that you keep them.

How long does a replatform take?

A single-storefront move onto Shopify Plus with the ERP and integration already stable is typically a few months; a multi-channel or multi-brand cutover, or one that also involves getting the operating core in order first, runs longer. The variable is rarely the storefront itself. It is the state of the data being migrated, the number of channels and trading partners that reconnect, and how much of the operating core has to be stabilised before the storefront can safely sit on top of it.

Can you add a B2B or wholesale ordering channel to our stack?

Yes, and it is a common reason operations-led businesses outgrow their current storefront. Wholesale selling brings account-specific pricing, catalogues and credit terms that a consumer storefront was never shaped for. Shopify Plus now runs B2B natively alongside your consumer store, and for more complex structures a composable stack can separate the two cleanly. Either way we architect it so wholesale orders land in the same operating core as every other channel, with one inventory position behind all of them.

Do you design the storefront, or work alongside our design agency?

Our work is the architecture and the operations behind the storefront: platform choice, the connection to your operating core, and a migration that does not cost you revenue. We are not a brand or conversion design agency, and we work well alongside the one you have. In practice the split is clean: they own how the store looks and converts, we own whether it holds up operationally as you grow.

How do you handle multi-channel and marketplace selling?

By making the ERP the single source of truth for stock and orders, and treating each channel, including marketplaces, as a connected endpoint rather than its own island. That means one live inventory position across the webstore, marketplaces and any physical channels, so you are not overselling on one channel while stock sits idle for another. The architecture is designed so adding the next channel is a connection, not a rebuild.

Do you work outside Sydney and Melbourne?

Yes, Australia-wide. Delivery is remote-first with on-site time where it earns its place. We regularly serve clients in Brisbane, Adelaide and Perth.
