This guide has been created by our partners, SparkLayer, the go-to B2B eCommerce platform.
At SparkLayer, we work with over 3,000 global B2B and hybrid brands to help them scale their businesses. One of the most common challenges we hear about is related to integrations and tech stacks.
For teams responsible for digital commerce, integrations are often the difference between a setup that quietly supports growth and one that becomes a constant source of friction.
While storefront features tend to get the most attention, it’s the connections behind the scenes that determine whether pricing stays accurate, orders flow smoothly, and internal teams can rely on the data they see.
As businesses grow, what starts as a simple setup often becomes more complex. New systems are added, processes evolve, and expectations increase, both internally and from customers. Integrations that once felt ‘good enough’ can quickly become limiting, especially when wholesale customers expect the same speed and clarity they experience in retail purchasing.
When Shopify is used to support more complex buying journeys, integrations stop being a background concern and start shaping how well the business actually runs. Pricing, accounts, repeat ordering, fulfilment, and reporting all depend on systems working together in a way that feels joined up.
This is particularly true when Shopify is being used as a central hub for B2B operations. At that point, integrations are no longer just technical connections; they actively influence efficiency, customer experience, and the ability to scale without unnecessary overhead.
This checklist is designed to help you sense-check your Shopify B2B integration strategy, without needing to dive into technical detail. It is intended to prompt the right questions and conversations, rather than prescribe a single “correct” setup.
A useful first step is to be clear about which problems belong in the buying experience and which belong in back-end systems. Solutions like SparkLayer are designed to handle areas like account-based access, customer-specific pricing, permissions, and ordering flows. Integrations should not try to replicate or override that logic elsewhere.
When this separation is unclear, teams often end up maintaining the same rules in multiple places. That increases the risk of errors and makes even small changes harder to manage. A clean boundary allows each system to do what it does best, without unnecessary overlap.
Instead, Shopify integrations should focus on ensuring that what happens during checkout flows cleanly into the systems that handle fulfilment, finance, and reporting.
Takeaway action: List which parts of your process must happen in the storefront and which should only happen after an order is placed.
If you’re using SparkLayer to manage customer-specific pricing or quantity breaks, that pricing should be treated as authoritative at the point of order. Your integrated tools should carry that information through, not reinterpret it.
Pricing discrepancies often lead to manual corrections, delayed fulfilment, or uncomfortable conversations with customers. Over time, these issues can erode trust in both the system and the buying experience.
Problems often arise when back-end systems expect simpler pricing models than the storefront is allowed to offer. Aligning expectations across systems early helps prevent these issues from becoming recurring operational headaches.
Takeaway action: Confirm that additional systems accept prices from Shopify as-is, rather than attempting to rebuild them.
Account-based buying adds a layer of complexity that Shopify integrations often ignore. Orders are rarely tied to just an email address – they’re tied to an organisation, a billing setup, and an internal approval process.
When that context is lost, teams are forced to infer intent or manually reconnect orders to the correct account, which introduces delays and increases the risk of mistakes.
Your Shopify integration setup should carry that contextual information throughout the journey. If orders arrive in back-end systems without that account-level information, teams are forced to reconstruct it manually.
Takeaway action: Review how account identifiers and relationships are passed through with each order.
From an integration perspective, it’s not enough for an order to exist in another system. It needs to arrive with enough detail to be processed without guesswork or manual admin.
Operations teams are often the first to feel the impact of incomplete integrations. Missing information slows fulfilment, increases internal queries, and can create avoidable delays for customers. This includes payment terms, purchase order references, delivery instructions, and any account-specific rules.
Takeaway action: Ask operations teams what information they are missing when an order first arrives.
Inventory integration is often approached as a technical syncing problem, but in practice, there are simpler ways to manage it. What matters most is confidence. If teams and customers cannot trust the availability shown, they will find workarounds that undermine the system altogether.
If the stock availability shown in Shopify doesn’t reflect reality, customers and internal teams quickly lose confidence. Helpful integrations make inventory information and behaviour understandable and consistent.
Takeaway action: Identify whether teams trust Shopify's stock levels when making commitments to customers.
Many Shopify setups support a mix of self-serve ordering and sales-assisted workflows. Integrations need to support both, without needing human touchpoints or manual reconciliation.
Inconsistent handling between these two paths can lead to confusion in reporting, fulfilment, and customer communication.
All orders placed by customers, and orders placed on behalf of customers, need to move through the same systems in the same way, carrying the same context and rules.
Takeaway action: Compare how self-serve and sales-assisted orders are processed downstream.
A common source of unnecessary complexity is duplicating logic across systems. If customer permissions, pricing rules, or ordering constraints already work well using SparkLayer, integrations shouldn’t attempt to recreate them elsewhere.
Duplicated logic increases maintenance effort and makes it harder to understand where issues originate when something goes wrong.
The role of the integration is to transport outcomes, not reimplement decisions.
Takeaway action: Identify any business rules that exist in more than one system and question why.
B2B eCommerce is the same as any business, and isn’t exempt from the changes within the industry and the economy. As a result, pricing strategies change, new customer groups emerge, and ordering rules need to change to maintain the bottom line.
Integrations built too rigidly can quietly become blockers to growth, forcing teams to delay changes or rely on temporary fixes.
Integrations should be flexible enough to accommodate these shifts without forcing changes to the buying experience. When building out a tech stack, you need to ensure your tools and systems can adapt and scale as your business does.
Takeaway action: Consider one likely commercial change and assess whether integrations would support it cleanly.
Strong Shopify integrations do not replace what existing tools already do; they should support them and make them more efficient and scalable.
When responsibilities are clearly defined, each part of the stack can evolve without destabilising or duplicating the rest. This is particularly important as order volumes increase and processes become more complex.
For many teams, this is where tools like Versori play an important role, helping connect Shopify and SparkLayer to the wider business in a way that remains flexible as requirements change.
