#SuccessStories - When Growth Outpaced Process: How Sia Put AI Agents into An Post's Finance Operations
1. Context
Parcel volumes have grown enormously with e-commerce, and finance processes built for a much smaller business can quickly become a bottleneck. AI agents can take on repetitive checks and drafting, provided they are grounded in real operational pain points and people keep control of decisions.
An Post's parcel volumes rose by 1,430% between 2015 and 2025, from 5 million to 86 million, with EUR 300 million of billings running on a process built for around 30 million parcels.
2. Client Challenge
An Post's business was under strain from its own growth:
- 40% of the finance team's day was absorbed by overcharge queries.
- Revenue was lost to manual interventions, sustained overtime and system limits on growth.
3. What Sia Did ?
Sia ran a rapid discovery, then put agents into production:
- Rapid discovery: an 80/20 diagnostic of where AI removes manual work and recovers revenue, scoped on remittances, Special Price Agreement setup and query handling.
- First agent: an agent for customer query handling that checked the agreed rate, calculated the variance and drafted the reply for the team to approve.
- Process first: one contained agent live first, then scale, with benefits set up front and measured each sprint against a 3x return target; every agent grounded in a real operational pain point.
4. Results & Outlook
The An Post team kept every decision and got time back for customers, with benefits measured each sprint against a 3x return target as the agents scaled.
By starting from the process and defining value before the build, Sia helps operators turn AI agents into measurable finance gains.
