ERP and systems integration

One set of numbers across your store, ERP and warehouse

We connect the systems your business runs on, so an order placed online shows up in the ERP, the warehouse ships it and finance sees the invoice, without anyone retyping it. Every flow is logged, retried and alerted, because the day an integration fails quietly is the day stock goes wrong.

  • Every failed sync caught and replayable
  • Documented flows you can hand to anyone

Signs your systems are not talking to each other

Someone retypes orders

Orders are exported from the store and keyed into the ERP by hand, and mistakes show up as wrong shipments and angry emails.

Stock is never quite right

The website sells items the warehouse ran out of yesterday, or hides items that arrived this morning.

Month-end takes a week

Finance reconciles payouts, refunds and invoices across three systems before anyone trusts the numbers.

Integrations fail silently

A sync stopped working on Tuesday and nobody noticed until Friday, when a customer asked where their order was.

What we connect

The flows most businesses need

Your ERP is usually the system of record. We connect the store, warehouse, CRM, payments and marketplaces around it, and agree for each piece of data which system owns it.

What makes an integration reliable

Moving data when everything works is easy. The design effort goes into timeouts, duplicates, half-finished writes and expired credentials, so none of them turn into a wrong order.

How a reliable sync works: event, validation, idempotent write, automatic retry with back-off and a review queue with an alert for anything that still fails
  1. Map

    1 to 3 weeks

    Every flow, field and owner written down, including what happens to refunds, splits and edits.

  2. Design

    1 to 2 weeks

    Choice of iPaaS or custom code per flow, error handling and monitoring agreed.

  3. Build

    3 to 8 weeks

    Flows built and tested against sandbox copies of your real systems.

  4. Parallel run

    1 to 2 weeks

    New flows run alongside the old process and the results are compared line by line.

  5. Monitor

    Ongoing

    Dashboards, alerts and a monthly review of failures and slow flows.

Questions

ERP integration FAQ

Which ERPs do you integrate with?

Most often NetSuite, SAP (Business One and S/4HANA), Microsoft Dynamics 365 and Acumatica, alongside Shopify, BigCommerce, Salesforce, HubSpot, 3PLs and payment providers. If a system has an API, a database we can read safely or a file export, we can usually connect it.

Should we use an integration platform or custom code?

Both have a place. An iPaaS such as Celigo, Boomi or Make is quicker for standard flows between common systems. Custom middleware is better when the logic is unusual, the volume is high or you want to avoid another subscription. We often mix them, and we will recommend one per flow.

What happens when a sync fails?

Every flow logs what it sent and received. Failures are retried automatically with a back-off, duplicates are prevented, and anything that still fails lands in a queue with an alert to the right person, who can fix and replay it.

How long does an ERP integration take?

A single well-understood flow, such as orders into NetSuite, can take a few weeks. A full set of orders, stock, prices, customers and invoices across several systems usually takes two to four months, most of it spent on mapping and testing edge cases.

Why do integrations cost more than people expect?

Because the hard part is agreeing what the data means in each system, not moving it. Our article on why connecting two systems costs more than building one explains where the effort goes.

Can you take over integrations another team built?

Yes. We audit the existing flows, add logging and alerts where they are missing, fix the failures that keep recurring and document what each flow does.
