A balance needs a clear record behind it.

Business records can span several projects, branches, or teams. Cashflow addresses this product problem through separate cashbooks inside a business workspace, so the interface has a clear place for each set of entries and its members.

Follow the workflow.

A closer look at the interface and the sequence it supports.

  2. 02

The thinking in the build.

Each choice connects a product constraint to an implementation detail.

01

Make the cashbook the organizing unit.

Challenge
A single headline balance does not explain which project or team a record belongs to.
Implementation
The current workspace starts with a searchable cashbook list. Each row exposes a book’s name, members, recent activity, and balance; desktop adds sorting and an overview, while mobile prioritizes the list.
Why it matters
The structure lets a visitor understand where records live before navigating into individual entries.
02

Put financial safeguards behind the interface.

Challenge
Roles, duplicate submissions, and closed periods cannot depend on the appearance of the UI.
Implementation
Server-side book access combines business membership and book permissions. The transaction route checks entry policies, closed dates, duplicate protection, and idempotency keys.
Why it matters
Access and entry rules stay enforceable beyond the interface, at the point where financial records are written.
03

Adapt the workflow for a smaller screen.

Challenge
Desktop search, sorting, and workspace controls need a different hierarchy on a phone.
Implementation
Mobile uses a workspace selector, a list-first book view, search/filter controls, a floating add-book action, and Cashbooks / Help / Settings navigation. The Android project uses Capacitor to host the web experience with device integrations.
Why it matters
The mobile layout retains the cashbook model while changing navigation and action placement. The Capacitor-based Android app is available on Google Play as Cashflow: Business Cashbook.
04 / THE RESULT

A clear route from business workspace to financial entry.

Cashflow brings cashbooks, entries, member access, and financial policies into a responsive product used by real users. Its Android app is available on Google Play as Cashflow: Business Cashbook, published by DelighTech. The desktop and mobile previews show how the workflow is presented at different screen sizes.

  • Separate cashbooks with balances and member context
  • Permission-scoped access to books and entry operations
  • Entry-policy checks and an Android Capacitor project
