Ledger Fiti builds automated Excel & Google Sheets systems, financial dashboards, and AI‑powered workflows — so freelancers and SMEs can focus on growth, not grunt work.
Tools I work with
What I Build
From complex financial models to end-to-end automation pipelines — every system is built for your exact workflow.
Custom VBA-powered workbooks — payroll systems, inventory trackers, fixed asset registers, financial models. Built for real workflows, not demos.
Apps Script automations, Google Form pipelines, connected multi-sheet systems that update in real time without manual input.
Interactive Power BI and Looker Studio dashboards that turn raw data into clear decisions. Connected to live data sources.
End-to-end pipelines using N8N, Zapier, and Make that connect your apps, eliminate copy-paste, and run 24/7 without you.
Claude and GPT-powered agents that classify documents, generate reports, respond to emails, and process data automatically.
Supplier reconciliation, withholding tax filing prep, invoice management workflows, and donor reporting — for lean finance teams.
The Process
No long onboarding. No IT department. Just a clear process and a system that works.
We map your current workflow and pinpoint exactly what's eating time and causing errors.
I deliver a custom system tailored to your exact process — not a template. You're involved at every stage.
Full walkthrough, documentation, and 30-day support. You own everything and are never left stuck.
Your team reclaims hours every week. Errors drop. Decisions get faster. You grow.

About
I'm Jason Gitonga — CPA and founder of Ledger Fiti. My background sits at the intersection of finance, data, and technology.
I started Ledger Fiti because I kept watching businesses spend hours on work that a well-built system could handle in seconds. Manual reconciliations, copy-pasted reports, approval emails going in circles — that inefficiency has a real cost: time, money, and stress.
Whether you're a freelancer who needs a cleaner way to track clients, or an SME whose finance team is buried in spreadsheets, I build systems that fit your exact workflow — not the other way around.
Social Proof
"Jason built an automated reporting tool that cut our monthly close from 3 days to half a day. Genuinely transformative for our team."
"The Excel payroll system was exactly what we needed. Clean, fast, and easy for any accountant to pick up and use."

"I didn't know a spreadsheet could do that. Now I can't imagine going back to how we worked before."
