Architecture
One Core, Every Application
One Core Runs the Whole Post
Counter, delivery and recognition on a single architecture and one data model, deployed as SaaS, sovereign cloud or on-premise, and proven in national estates above 45,000 branches.
The "Integration Tax"
Most operators run the counter on one system, delivery on another and sorting on a third, then spend years and millions wiring them together. Every new service means another integration, another vendor and another point of failure.
When every system keeps its own version of the truth, the parcel accepted at the counter never quite matches the one the driver delivers or the one finance reconciles. Errors hide in the gaps.
One Core, One Model
Every channel and application shares the same core, so the parcel accepted at the counter is the parcel the driver delivers and the parcel finance reconciles. Add, replace or retire individual components, with no lock-in to our hardware, hosting or modules.
Five Layers, One Data Model
Engagement channels, business applications, platform services, integration and data run on a shared core, so counter, delivery and recognition work from one operational record, not synchronised copies.
Transaction Integrity at the Core
A journaled engine writes every event to an immutable record and replicates it across the estate, so branches keep trading through outages and transactions can be reconstructed years later.
Configuration, Not Code
Products, tariffs, surcharges and regulatory variants live in configuration, so you set up the Post you run today without bespoke development and change it without waiting on a release.
Escher’s platform runs more than half of the world’s top 20 Posts, including national estates above 45,000 branches and networks connecting 1.5 billion consumers. The same core has run on the Riposte platform since 1993, extended rather than replaced.
IT & Procurement Confidence
Deployment: Cloud-native SaaS, sovereign cloud or on-premise, from one codebase with the same upgrade path.
Availability: 99.95%+ targets measured monthly and backed by service credits, with offline counter operation when the network degrades.
Scale: Peak-proven throughput sized for your busiest hour, across estates above 45,000 branches on a single national deployment.
