Usage-cost estimates
Translate prospective usage into a cost estimate that pre-sales teams can use in client discussions.
Back to work
XACT cost calculator
Built a calculator to help pre-sales teams estimate high-volume usage costs for the XACT banking platform and onboard clients.
My roleDeveloper
Overview
Pre-sales teams needed a way to estimate usage costs for prospective banking-platform clients, especially at high volumes.
Project statusPre-sales tool
Scope
A calculator for estimating high-volume usage costs during banking-platform pre-sales and onboarding. My contribution is the calculator, rather than ownership of the entire platform.
Main features
High-volume scenarios
Support estimation for clients whose expected platform usage makes manual costing harder to compare.
Onboarding support
Give the commercial team a concrete tool to support early client planning and onboarding conversations.
Technology
React & TypeScript
The supporting administrative web platform.
TanStack Query & Router
Data fetching and navigation in the host interface.
Tailwind CSS
Styling and interface composition in the host frontend.
Python & AWS CDK
Infrastructure in the supporting backend.
Stack shown is the supporting platform identified in the project source, not a claim that every component powers the calculator itself.
Engineering approach
Make the estimate useful in a sales conversation
The aim was a repeatable costing aid for prospective usage, giving pre-sales a concrete basis for discussing volume and expected cost.
Keep estimation claims bounded
The reported 80–90% accuracy is an approximate project estimate. A formal benchmark definition and evaluation period are not available for this public case study.
What I worked on
- Built the cost calculator for the XACT banking platform.
- Supported high-volume usage estimates and the client-onboarding process.
Results & scope
80–90%
approximate cost-estimation accuracy
- Approximately 80–90% cost-estimation accuracy.
- Gave the pre-sales team a tool for estimating platform usage costs when onboarding clients.
The accuracy figure is an approximate project estimate.
