Propell AI provides an AI-driven solution that helps businesses automate invoice processing and reduce manual accounting work. Its product is designed to sit on top of existing accounting environments, streamline document handling, and improve financial visibility across the invoice lifecycle.
To make that value usable in real business environments, the solution needed to connect reliably with a wide range of ERP systems, accounting platforms, and external data sources. HBM partnered with Propell AI to build a robust cloud-based integration platform that could support these connections at scale, handle high data volumes, and remain configurable as the product expanded into new markets and use cases.
The scope included the integration platform itself, integrations with ERP systems and e-invoice access points, a Data Lake for storing platform data, and an administration portal for onboarding, configuration, and operational control. HBM was responsible for full-cycle delivery of the platform, from architecture and infrastructure setup to development, testing, and DevOps, while Propell AI led solution architecture direction and requirements definition.
Our collaboration resulted in a production-ready integration platform that gives Propell AI a strong technical foundation for continued growth.
Key outcomes included:
Propell AI needed a scalable foundation that could support product growth, client onboarding, and increasing transaction volume without creating operational complexity.
Key challenges included:
“We have been delighted to work with such talented, professional, and skilled people as the PAI team in HBM.
They solve all challenges we send their way, and they keep on challenging us as well, so that we together can create a world-class IPAAS.
I'm very impressed by the fact that even under extreme circumstances, they have been able to deliver service with a world-class quality.”
CTO at Propell AI
HBM is responsible for full-cycle development of the Integration Platform. While Propell AI is accountable for Solution Architecture and requirements, HBM takes the responsibility for delivering the solution, including:
The project started in July 2021 when the first team members were onboarded.
At the active project stage, the team on the HBM side included 5 backend developers, 1 front-end developer, 2 test engineers, 2 DevOps engineers and a part-time project manager. The team was eventually scaled down when the platform core was finished.
The scope of the project includes the platform itself, integrations with 20+ ERP systems, integrations with e-invoice access points, building a Data Lake, as well as UI for administration and configuration. By now, the solution and first integrations are running on Production. Development of more integrations continues.
Designed a scalable IPAAS architecture focused on configurability, reuse, and reliable integration across multiple ERP systems.
Delivered full-cycle development of the platform, including the .NET integration core and React-based administration portal.
Ensured platform stability and performance through continuous testing under high-load and real-world conditions.
Implemented Azure-based, event-driven infrastructure using Terraform, enabling automatic scaling and consistent deployments.
