Chicago Startup Nuntiq Launches AI-Powered AP Receiving Platform to Automate Invoice Intake

Chicago-based software firm Nuntiq has launched AP Receiving, an accounts payable intake platform designed to automate the initial capture and validation of invoices for mid-sized and enterprise organisations. By centralising disparate invoice streams into a single AI-driven queue, the tool aims to eliminate the manual triage that remains a significant bottleneck in corporate finance workflows.

What was announced

AP Receiving is built to handle the "first mile" of the accounts payable process, aggregating invoices from email, supplier portals, direct uploads, and APIs. The platform also supports structured e-invoice formats including UBL, CII, Factur-X, and ZUGFeRD, positioning it for use by US companies with European operations facing increasing e-invoicing mandates. The system is designed to read and validate data against a company's specific business rules before the information is released to the ERP.

The platform employs a multi-model AI strategy, selecting specific models from various providers for different capture rules. This architecture allows Nuntiq to swap in newer or more efficient AI models as they become available without requiring customers to reconfigure their integrations. The company states that customer documents are never used to train these underlying AI models. According to research from Ardent Partners cited by Nuntiq, only 38 in 100 invoices currently achieve touchless processing, a gap the platform intends to close by ensuring only clean data moves forward.

Data is processed and stored on Amazon Web Services (AWS), currently operating out of the US East region, with further regions brought online as customer needs dictate. Security measures include dedicated databases for each customer’s transactional data and encryption at rest using AWS Key Management Service with scheduled automatic rotation. The system connects to existing ERP and procurement software via a documented REST API, allowing internal IT teams to maintain the integration themselves.

The companies involved

Nuntiq is a newly established software company headquartered in Chicago, Illinois. The firm focuses on the specific niche of accounts payable intake, serving both direct enterprise clients and the third-party service providers who manage AP functions on their behalf. The company enters the market with a focus on regional data residency and a connector framework designed for existing accounting and procurement ecosystems.

The company was founded by Ewout Vocking, who brings over a decade of experience to the venture. Vocking has been involved in implementing procure-to-pay and finance automation projects since 2012, a period during which the industry saw significant advancement in downstream functions like payment execution and approval workflows, but often lagged in the initial data capture phase. Nuntiq differentiates itself by operating as a specialized layer that sits in front of existing ERP systems rather than attempting to replace them. By focusing exclusively on the intake step, the company aims to provide a clean data feed for the broader finance stack, leveraging modern cloud infrastructure and swappable AI components to maintain technical relevance as the underlying LLM landscape evolves.

What this means

The launch of AP Receiving highlights a shift in the fintech sector away from monolithic ERP modules toward specialized "best-of-breed" intake layers. As AI-driven extraction becomes commoditized, the value proposition for finance teams is moving from the extraction itself to the orchestration and validation of data. Legacy OCR providers that rely on rigid, supplier-specific templates are under increasing pressure from this more flexible, model-agnostic approach. However, a significant question remains for the sector: as major ERP vendors integrate their own native AI capture tools, can standalone intake platforms maintain enough of a performance lead to justify their place in a company's software stack?
