Time Tracking and Invoicing Without the Bloat

Built for solo consultants and small firms who bill by the hour. No dashboards you'll never use, no integrations you didn't ask for. Just clean time entry, honest invoices, and clear reports.

Category 1

Time Tracking

  • Day and Week Time Entry

    Enter billable hours by day or week. Week view shows tasks as rows with day columns for fast data entry across an entire week.

  • Bulk Month Fill

    One click fills a set number of hours for every weekday in a month for a given task. Perfect for retainer engagements.

  • Project-Task Association

    All time entries link to a project and task. Hours roll up automatically for invoicing and reporting.

Category 2

Expense Management

  • Expense Tracking

    Record expenses by date, project, category, and amount. Attach scanned receipts as PDF files.

  • Expense Categories

    Preconfigured categories (Entertainment, Meals, Lodging, Mileage, Transportation, Other) with custom category support. Archive or delete unused categories.

  • Receipt Attachments

    Attach PDF files to expenses as scanned receipt documentation. Files stored and linked to the expense record.

Category 3

Projects & Clients

  • Client Management

    Full client records with name, address, currency preference, and configurable invoice terms (Net 15/30/45/60 or custom).

  • Contact Management

    Multiple contacts per client with name, email, title, phone, mobile, and fax. Contacts receive invoices directly.

  • Project Management

    Projects grouped by client with All/Active/Archived filtering. Edit, duplicate, archive, or delete projects (guarded — no deletion if time recorded).

  • Task Management

    Tasks belong to projects with individual billable rates. Archive tasks to hide from time entry. Delete only when no time recorded.

  • Client-Based Organization

    Everything flows from clients: projects, tasks, time, expenses, invoices, contacts. One clean hierarchy.

Category 4

Invoicing

  • Invoice Creation Wizard

    Step-by-step: select client, choose projects, pick time period (all uninvoiced, current month, last month, custom range), include expenses, enter invoice details.

  • Weekly Line Items

    Invoices break down billable time by week with hours, rate, and line total. Expenses appear as separate line items. Running total at bottom.

  • Invoice Lifecycle

    Track invoices through draft, sent, paid, and written-off statuses. Full history log of every state change.

  • Invoice Filtering

    Filter invoice list by client, date range, and status. Sort by any column. Quick view of outstanding vs paid.

  • PDF Invoice Generation

    Generate formatted PDF invoices for download or email. Invoice layout mirrors the on-screen detail view.

  • Invoice Email Delivery

    Send PDF invoices directly to client contacts via email. Invoice history tracks sent status and dates.

Reporting

  • Accounts Receivable Report

    Standard AR report showing all outstanding invoices with aging. Know exactly what's owed at a glance.

From Time Entry to Payment

  1. Step 1: Track

  3. Step 3: Send

    Generate PDF and email directly to client contacts. Invoice history tracks delivery and payment status.

  4. Step 4: Report

    Run AR and invoice reports. Export to CSV. Know what's owed and what's been paid.

Development

100% Built by Claude

Every tool in the Renkara fleet was built by Claude (Anthropic) working alongside a single human supervisor. Every line of code, every test, every deployment: AI-authored with human direction. The leverage factor across the fleet runs in the 20x–50x range, with individual sessions regularly exceeding 100x.
