The Growth Project
Systems Integration
API design, data pipelines, and middleware that connect the platforms your business already runs on, ecommerce, CRM, ERP, warehousing, and marketing systems. Data flows where it needs to without manual workarounds or spreadsheet bridges, following a four-step process from system audit to cutover with 30 days of post-launch monitoring.
API design, data pipelines, and middleware. We connect your systems so data flows where it needs to, without manual workarounds or spreadsheet bridges.
What do we actually build?
API Design, RESTful and event-driven APIs built for reliability. Versioned, documented, and tested with contract-first design using OpenAPI and AsyncAPI specifications.
Data Pipelines, ETL, real-time streaming, and batch processing. Data moves from source to destination with validation, logging, and retry logic built in.
Middleware, Message queues, event buses, and integration layers. Systems that decouple your services so one failure doesn’t cascade across your operations.
What changes after integration?
| Before integration | After integration |
|---|---|
| Manual data entry, staff copying orders between systems. Errors compound. Time wasted on data that should flow automatically. | Automated data flow, orders, inventory, and customer data sync in real time. No human in the loop for routine transfers. |
| Spreadsheet bridges, CSV exports stitching systems together. Data is stale by the time anyone reads it. No single source of truth. | Single source of truth, one canonical dataset. Every system reads from the same place. Reports match because the data matches. |
| Siloed reporting, each system has its own dashboard. Nobody agrees on the numbers. Decisions made on conflicting data. | Unified dashboards, cross-system visibility in one place. Sales, ops, and finance look at the same numbers and make aligned decisions. |
| Brittle point-to-point connections, direct integrations that break when either side updates. No error handling, no retry logic, no visibility into failures. | Resilient architecture, event-driven middleware with retry logic, dead-letter queues, and alerting. One system going down doesn’t take the rest with it. |
Which systems can we connect?
We integrate the platforms your business already runs on. No rip-and-replace. We connect what you have.

| ERP & Accounting | Xero, MYOB, NetSuite, SAP Business One |
| Warehousing & Logistics | ShipStation, StarShipIT, Cin7, Dear Inventory |
| Marketing & Email | Klaviyo, Mailchimp, ActiveCampaign, Braze |
| Integration Platforms | MuleSoft, Boomi, n8n, custom middleware |
How does the integration process work?
Every integration follows the same proven process. No surprises. No scope creep. Clear milestones from discovery to cutover.
01. System audit
We map every system, data flow, and manual workaround. You get a complete picture of what connects to what, and where data gets lost, duplicated, or delayed. We document every API endpoint, webhook, CSV export, and manual process your team uses today. Typically takes 1-2 weeks depending on the number of systems.
02. Architecture design
We design the integration architecture. API contracts, data models, error handling, and retry logic. You review and approve before we write a line of code. We choose the right pattern for each connection, direct API calls for simple integrations, message queues for high-volume flows, and event-driven architecture for real-time requirements.
03. Build and test
We build the integration with automated tests, contract validation, and staging environments. Every data path tested with real payloads before it touches production. We implement circuit breakers to prevent cascade failures, dead-letter queues for failed messages, and structured logging so you can see exactly what data moved where and when.
04. Cutover and handoff
Planned migration with rollback capability. Your team gets documentation, runbooks, and training. We monitor for 30 days post-launch to catch anything we missed. If a vendor updates their API or a new system needs connecting, we can extend support on a retainer basis.
Who is this for?
Ecommerce & retail, Multi-channel retailers connecting WooCommerce or Shopify to ERP, warehouse, and marketing systems. Orders, inventory, and customer data flowing automatically.
Professional services, Agencies, consultancies, and service businesses connecting CRM, project management, time tracking, and invoicing. One system of record for client work.
We connect your ERP, CRM, ecommerce, and operational systems. Data flows automatically. Reports align. Your team stops being the middleware. Tell us which systems you need connected and we’ll outline the integration approach with a realistic timeline, no obligation.
Common questions
How long does a typical integration project take?
Simple point-to-point integrations (e.g., WooCommerce to Xero) take 2-4 weeks. Complex multi-system integrations with data migration typically take 6-12 weeks. We always start with a 1-2 week audit so we can give you an accurate timeline before committing to the build.
What happens when a vendor updates their API?
We build integrations with versioned API contracts and automated monitoring, so breaking changes are caught before they affect your data flow. For ongoing support, we offer monthly retainer arrangements that include API version management and incident response.
Should we use an iPaaS like MuleSoft or build custom?
For businesses with 3-5 systems and straightforward data flows, custom integrations are usually simpler and cheaper. For larger enterprises with 10+ systems, an integration platform like MuleSoft, Boomi, or n8n makes sense. We recommend the right approach during the audit, we don't have a financial relationship with any platform vendor.
Can you migrate our historical data during integration?
Yes. We handle data cleaning, deduplication, format transformation, and validation before migrating historical records. We always run the migration in staging first with your team reviewing the results before touching production data.
What if one of our systems doesn't have an API?
Many older systems don't expose modern APIs. We've integrated with systems that only support CSV exports, SFTP file drops, email-based workflows, and even screen scraping as a last resort. The audit phase identifies these constraints so we can design the right approach for each connection.
