Ledger
How Flat18 shaped a simple money-tracking app for informal loans, project budgets, shared costs, receipts, and read-only records people can trust.
Ledger
A lightweight record for money lent, spent, repaid, and shared without accounting jargon or spreadsheet maintenance.
Delivered for confidence
Ledger keeps the balance, receipt evidence, private context, corrections, and public sharing controls in one understandable workflow.
Many money situations are too important for scattered notes, but too small for full accounting software. Ledger gives each person, project, trip, or shared expense a dedicated record with plain labels, receipts, reports, and controlled public links.
Problem found
Informal balances get split across messages, banking apps, receipts, screenshots, and memory, which makes sensitive money conversations harder.
Flat18 diagnosis
Users needed a shared factual record, not accounting concepts. The product had to feel as quick as a note and more trustworthy than a spreadsheet.
Solution shipped
We designed ledgers with type-specific labels, fast entries, optional receipt detail, preserved edit history, small reports, and read-only sharing.
Customer value
People can explain what happened, when it happened, what evidence supports it, and what the balance is now without exposing private notes.
