ERP Integration
What we've learned so far
An integration is what lets one version of the truth exist. Without it the same customer exists twice, stock is accurate in the warehouse and optimistic on the website, and finance reconciles by hand at month end. That is usually called inefficiency, which understates it. People spend their week retyping, decisions rest on numbers nobody trusts, and growth stops at the point manual reconciliation can no longer absorb the volume.
Nearly every failure we have seen traces back to one omission. Your ERP assumes it is the system of record. So does Shopify, Magento, WooCommerce and every other commerce platform. Stock, price, customer and order each need one owner and one direction of travel, and bidirectional sync on the same field produces conflicts that look random and are not. Getting this right is what prevents the two most expensive ecommerce failures: selling what you cannot ship, and shipping against a price that was wrong.
Inventory is the hardest part, and real-time sync is usually the wrong target. A webhook firing on every warehouse movement will hit platform rate limits and leave the store further behind than a scheduled sync would. We match cadence to how the business actually sells and reserve immediate updates for the lines where overselling is expensive. The damaging failures are partial ones. A connection that is down is obvious within minutes. One that syncs most records and drops the rest runs for weeks, and you find out through a customer promised stock that does not exist.
Two things have changed recently. Product data is now read by shopping agents as well as by customers, because the major platforms syndicate catalogues into AI channels by default, so inaccurate stock or pricing no longer costs you only a basket on your own site, it misrepresents you inside a conversation you cannot see. And AI has made connectors cheap to build, which makes the build-versus-buy decision easier to get wrong. A connector platform is correct for standard flows. It stops being correct the moment your pricing, bundles or B2B rules are unusual, which for wholesale and multi-channel businesses they usually are. What has not become easier is deciding what happens when a record exists in one system and not the other, choosing a cadence the business can absorb, and naming who is accountable when it breaks at two in the morning. That last question is the most neglected in this category. We answer it in the proposal, because an integration nobody owns is a defect with a delay on it.

How we work
Establish which system owns what
Stock, pricing, customers and orders each need one owner and one direction of travel. Whether the storefront is Shopify, Magento, WooCommerce, BigCommerce or something custom, this decision comes first and everything else follows from it.
Map the data models against each other
Every ERP models products, tax and units of measure differently from every commerce platform. Variants, kits, bundles and customer-specific pricing get resolved on paper before anything is built.
Decide how fast each record needs to move
Stock usually near real time, catalogue data less often, financial records on a schedule. Constant syncing costs money, hits rate limits and rarely improves anything.
Build the sync with its safety net
The connection plus retries, queuing, idempotency and reconciliation, so an order cannot vanish silently between two systems at two in the morning.
Make it easy to work with
Operations need to see what synced, what failed and why, in their language, and be able to retry it themselves rather than raising a ticket.
Reconcile before you trust it
Run both in parallel and check totals daily until they agree. The reconciliation is what finds the mapping errors that testing did not.
Where this isn't the right fit
If your ERP vendor or your commerce platform offers a supported connector that covers your flows, use it. Somebody else maintains it when an API changes, and that is worth a great deal. Custom work earns its place when pricing logic, catalogue structure or B2B rules fall outside what the standard option handles, which for wholesale and multi-channel businesses is common.
If the ERP data is inconsistent, integration will publish that inconsistency to customers faster than anyone was managing by hand. Clean the source first. If you are mid-way through replacing the ERP, wait and integrate with the system you are keeping. And if what you need is a one-time load rather than an ongoing sync, that is migration work at a fraction of the cost.
