Systems Integration Hub
A central layer that keeps your CRM, ERP, accounting and e-commerce tools in sync, with retries, monitoring and one place to see what moved.

What it is
Point-to-point connections are easy to add and hard to live with. An integration hub gives every system one documented place to send and receive data, so a change in one tool doesn't quietly break three others.
A systems integration hub is a dedicated service that sits between your business applications and moves data between them by rule. When an order is placed, a customer record changes or an invoice is paid, the hub picks up the event, translates it into the format each receiving system expects and delivers it, keeping a record of every step.
It usually replaces a tangle of direct connections built up over the years: a sync plugin here, a scheduled export there, a script on someone's laptop and a few no-code automations nobody remembers setting up. Each one works until it doesn't, and when data stops flowing, nobody knows where to look first.
With a hub in place, there's one place to see what moved, what failed and why. Failed messages are retried or held for review instead of silently dropped. Replacing a tool becomes a contained project, because only its connector changes, not every system that talks to it.
Why organizations reach for this
Signs you might need one
If several of these sound familiar, a system of this type is probably worth a conversation.
- Orders, customers or invoices regularly go missing between two systems, and someone fixes them by hand.
- An integration broke after a vendor update, and it took days to work out where.
- You run a dozen no-code automations and nobody is sure which ones still matter.
- The same customer has a different address in your CRM, your accounting software and your shipping tool.
- Replacing one application is on hold because nobody knows what else depends on it.
- A critical sync runs as a script on one person's computer.
What's usually included
The building blocks
A typical system of this type includes most of the following. Your version keeps what you need and leaves out what you don't.
-
01
A connector for each system
A dedicated, tested adapter for every application that handles its authentication, rate limits and data format in one place.
-
02
Shared data model
Common definitions for customers, products, orders and invoices, so each system translates to one format instead of to every other system.
-
03
Field mapping and transformation
Documented, version-controlled rules for converting codes, units, currencies, tax settings and statuses between systems.
-
04
Event and schedule triggers
Changes pushed in real time through webhooks where a system supports them, and collected on a schedule where it doesn't.
-
05
Retries and failure queues
Temporary failures retried automatically, and persistent ones parked with full context so someone can fix and replay them.
-
06
Monitoring and alerting
A dashboard of message volumes, failures and delays, plus alerts to the right people when a connection stops behaving.
-
07
Message log and replay
A searchable history of every record that moved, when and where, with the option to resend a corrected message.
-
08
Security and credential management
Credentials kept in a managed vault, least-privilege access for each connector, and data encrypted in transit and at rest.

PartnersEDI, SFTP and partner APIs
Legacy systemsOn-premises databases and files
Systems it typically connects to
- CRM (Salesforce, HubSpot, Microsoft Dynamics 365)
- ERP (NetSuite, SAP, Microsoft Dynamics 365 Business Central)
- Accounting (QuickBooks, Xero, Sage Intacct)
- E-commerce (Shopify, BigCommerce, Adobe Commerce)
- Warehouse and shipping (ShipStation, ShipBob, EasyPost)
- Payments (Stripe, Adyen, PayPal)
- Marketing platforms (Mailchimp, Klaviyo, Braze)
- Partner and legacy systems (EDI, SFTP file drops, on-premises databases)
Who it tends to suit
- Companies whose core data now lives in several applications that have to agree
- Retailers and brands syncing orders, stock and customers across sales channels
- Organizations planning to replace a core system without disrupting everything around it
- Businesses exchanging orders or files with partners through EDI, SFTP or APIs
- Teams that have outgrown a pile of no-code automations
How it would be delivered
Four phases, each one usable
Durations are indicative for a typical scope. Your proposal will include a dated schedule.
-
01
Integration audit
We list every system, existing connection and data flow, note what breaks and why, and agree on the target architecture.
2–3 weeks -
02
Hub foundation and first flow
The core service, logging, monitoring and your highest-value integration, live in production so the pattern is proven early.
4–6 weeks -
03
Move the remaining flows
Existing connections rebuilt on the hub one at a time, each run in parallel with the old version until the results match.
6–10 weeks -
04
Retire and hand over
Old scripts and automations switched off, runbooks written for common failures, and your team trained on the monitoring dashboard.
2 weeks
