Your business runs on custom-built software. Or heavily customised off-the-shelf. It has no API. The vendor won't help. We build the integration layer and connect it to everything else.
Perth-based. Australia-wide. We specialise in systems others won't touch.
Someone built the ERP. Or the CRM. Or the job management system, the asset tracker, the client portal. It was built for your business, or heavily customised to fit. And it works. The business depends on it.
But it doesn't talk to Xero. It doesn't sync with your CRM. Reports come out as CSV exports. There's no API. The vendor either can't or won't help with integration. And replacing the system would mean losing years of customisation.
HELLO PEOPLE is a Perth-based software consultancy. We specialise in connecting custom and legacy systems to modern platforms. We build the integration layer your system was never designed with, so your data flows where it needs to without replacing what works.
If your business depends on a system that nobody else can connect to, you probably recognise these.
Your system was built custom. Or it's an industry-specific ERP from a vendor who never prioritised integration. There's no API documentation, no webhook support, no Zapier connector. Just a database and maybe an export button.
You asked the vendor about connecting to Xero or your CRM. They said "we don't support that" or quoted $200K for a custom connector. Or they simply stopped responding because the product is end-of-life.
An order in the ERP gets re-typed into the accounting system. A customer update in the CRM doesn't reach the ERP. Staff maintain records in two or three places to keep everything in sync.
Your ERP or CRM has been customised over many years. Custom fields, custom workflows, custom reports. Moving to a standard platform would mean losing functionality your business depends on.
The system runs on .NET Framework, classic ASP, FoxPro, Progress 4GL, or some other technology that modern developers don't touch. Finding someone who can work on it is expensive and slow.
Only the vendor can make changes. They charge per hour. They control the timeline. You can't get your data out easily. And switching means starting from scratch.
Tell us what systems you are running and what is not connecting properly. We map the gap, find what needs to be built, and give you a fixed-price quote before you commit to anything.
What does it do? What's it built on? What systems does it need to talk to? Share the details and we'll assess it.
API builds, cloud sync, middleware, data extraction and gradual modernisation. Here is what we deliver.
We reverse-engineer your system's database, understand the business rules and build a secure REST API on top. Authentication, rate limiting, field-level access control and documentation included.
Works even when the vendor provides no API. We work at the database level, respecting the application's data integrity rules.
For businesses whose custom system has no API and no integration options from the vendor.
Your custom ERP or CRM syncing with Xero, MYOB, Salesforce, HubSpot, Shopify or any cloud platform. Bidirectional where needed — changes in either system flow to the other.
We handle the complexity: data mapping between different schemas, conflict resolution for bidirectional sync, and error handling for records that don't match.
For businesses that need their custom system data in cloud software their team uses daily.
For complex environments with multiple systems that all need to share data. We build a central middleware layer that routes data between systems, transforms formats, handles errors and provides a single monitoring dashboard.
Event-driven architecture. Systems publish events. Subscribers receive what they need. New systems plug in without changing existing ones.
For businesses with three or more systems that need to share data reliably.
Your data, out of the system, into a format you own. Regular exports to your data warehouse, reporting database or cloud storage. You're no longer dependent on the vendor for access to your own data.
Automated, scheduled, with full audit trails. Historical data extracted and ongoing changes captured incrementally.
For businesses where the vendor controls data access and you need independence.
Replace one module at a time. Keep the custom system running for what it does well. Build modern replacements for the parts that are holding you back. The integration layer bridges old and new.
Strangler fig pattern — modern modules gradually take over functionality from the legacy system. No big-bang migration risk.
For businesses whose system is too large and complex to replace in one go.
Bug fixes, performance tuning, small enhancements and security patches for your custom system. We become the support team that the original developer isn't available to be.
We learn the system, document it, stabilise it and keep it running while you plan the long-term strategy.
For businesses whose system is critical but the original developer or vendor has moved on.
We build the integration layer your system was never designed with. Your ERP talks to Xero. Your CRM syncs with HubSpot. Your internal system pushes data to Shopify. Whatever the combination, we make it work.
The custom system stays as it is. The integration handles the data flow.
We build a REST API that sits on top of your custom database. Documented, authenticated, rate-limited. Any modern system can now connect to your ERP/CRM without touching the database directly.
Your vendor may not provide an API. We build one anyway, by understanding the data model and business rules.
Replacing a custom ERP or CRM is a massive project. Often unnecessary. If the system does what it does well, just connect it to the modern tools your team needs.
Integration is faster, cheaper and lower risk than rip-and-replace. You can always migrate later with the integration layer already in place.
Reports in Power BI. Data in a warehouse. Records available to other departments. The integration breaks the data out of the locked-in system and makes it available where it's needed.
No more depending on the vendor to provide reports or exports.
The integration layer maps every data entity, relationship and business rule. When (if) you decide to replace the system, the hard work of understanding the data model is already done.
Migrate in stages. Replace modules one at a time. The integration layer becomes the bridge between old and new.
Every custom system is different. We scope after discovery, never before.
Tell us about the system: what it does, what it's built on, what needs to connect. We'll assess complexity and give you a realistic range.
After reviewing the system architecture and data model, we quote a fixed price for the integration or API build. No hourly creep.
Monthly plans for integration monitoring, legacy system maintenance and evolution. Your systems looked after properly.
A wholesaler running its operations on a fragile Microsoft Access database — single-user lockouts, occasional corruption, no remote access — was migrated to a modern web app on a proper database. All historical data preserved, forms and reports reproduced, and the workflow extended to mobile crews.
Read the full case studyYour custom or legacy system at the centre. API layer, middleware and sync connecting it to the modern platforms your business needs.
Every custom system is different. The process adapts, but the structure stays the same.
We write proper integration code: API connections, data mapping, error handling, logging. Not Zapier chains that break quietly.
You get a clear price before we start. No hourly billing that spirals. No surprise invoices at the end of the month.
We understand BAS, GST, super, award rates, Australian privacy law, and the platforms local businesses actually use.
You talk to the people building your integration. No account managers, no offshore handoffs, no ticket queues.
APIs change. Platforms update. We monitor, maintain, and evolve your integration so it keeps working as your business grows.
We had a custom ERP built fifteen years ago. No API, no documentation, the original developer retired. HELLO PEOPLE reverse-engineered the database, built an API, and connected it to Xero and our new CRM. We didn't have to replace the ERP. It just works with everything now.
Every industry has its own custom and legacy systems. The business logic inside them is irreplaceable. The integration just connects them to the rest of the world.
Custom ERP for production scheduling, BOM management and quality tracking. We connect it to accounting, warehouse management and eCommerce without replacing the system your factory depends on.
Custom dispatch, routing and fleet management systems. We connect them to customer portals, accounting and real-time tracking platforms.
Asset management, maintenance scheduling and compliance systems built for specific operations. We integrate with SAP, financial reporting and safety compliance platforms.
Custom patient management, rostering and billing systems. We connect them to Medicare, accounting, HR platforms and government reporting systems.
Legacy systems for asset management, citizen services, billing and compliance. We connect them to modern portals, payment gateways and reporting platforms.
Custom practice management, time tracking and client billing systems. We connect them to accounting, document management and CRM platforms.
Yes. We work at the database level, reading and writing data directly using the system's data model and business rules. Or we use file-based integration (the system exports, we pick it up). Where possible, we build an API on top so future integrations are easier.
Not necessarily. We can work with the database directly and build integration at that level. If we need to modify the application logic, it gets harder without source code, but database-level and file-level integration usually covers what's needed.
Pricing depends on the systems involved, the volume of data and the exception cases. We provide a fixed-price quote after a 15-minute scoping call — no hourly billing, no surprises.
Yes. If the original developer or vendor is gone, we take over support. Bug fixes, performance tuning, security patches and small enhancements. We learn the system, document it and keep it stable.
Sometimes, yes. But often the system does 80% of what you need and replacing it is a massive project with significant risk. Integration lets you keep the 80% and fill the gaps with modern tools. We'll give you an honest assessment of which path makes more sense.
We've worked with .NET Framework, classic ASP, FoxPro, Progress 4GL, Delphi, VB6 and systems built on technologies most developers haven't heard of. The database is usually more accessible than the application, and that's where integration happens.
We design integration to be resilient. Database-level integrations monitor for schema changes. API-level integrations use versioning. We include alerting so you know immediately if something changes. Most vendor updates don't break the integration.
A single-system sync takes 6 to 10 weeks. API layer builds take 8 to 14 weeks. Full middleware environments take 12 to 20 weeks. We scope precisely after the discovery phase. Custom systems vary widely in complexity.
