How to Build a Timesheet App With Bubble

Tracking billable hours across spreadsheets creates billing errors and delays that cost real revenue. Bubble's no-code platform lets you build a custom timesheet app with project allocation, manager approval workflows, and billing exports all running in one connected system without writing backend code.

Bubble replaces disconnected spreadsheets with a structured tool your team actually uses. Employees log time against projects, managers approve submissions, and finance exports billing-ready reports in minutes rather than days.

Key Takeaways

• Project-based logging: Employees allocate hours to specific projects and tasks with notes, keeping billing data organized by client.
• Draft and submit: Time entries save as drafts during the week and submit as a complete timesheet for manager review.
• Approval workflow: Managers review, approve, or reject weekly timesheets with comments; approved records lock automatically.
• Billable split: Reports separate billable and non-billable hours per project and client for accurate invoice generation.
• CSV export: Billing and payroll teams export approved timesheet data in one click without manual data extraction.
• Role-based access: Employees see their own timesheets; managers see their team; finance accesses all approved records.

What Data Architecture Does a Bubble Timesheet App Need?

A Bubble timesheet app requires six data types: Employee, TimesheetEntry, Project, Task, ApprovalRecord, and BillingRecord.

Modeling these types correctly before building any page ensures approval workflows, reporting queries, and billing exports run without requiring complex workarounds later.

• Employee type: Stores role, department, manager reference, hourly rate, and billable flag for reporting calculations.
• TimesheetEntry type: References Employee, Project, and Task; stores date, hours, notes, billable flag, and status field.
• Project type: Holds project name, client reference, budget hours, billing rate, active status, and assigned team members.
• Task type: References Project, stores task name, estimated hours, task type, and billable flag for entry filtering.
• ApprovalRecord type: Links to a weekly timesheet group, stores approver, decision, timestamp, and rejection comment field.
• BillingRecord type: Aggregates approved TimesheetEntry records by project and period for invoice and payroll export use.

How Do You Build Time Entry and Project Allocation in Bubble?

Employees use a daily or weekly time entry form to select a project and task, enter hours and notes, and save as a draft before submitting the full week.

A clean entry interface reduces friction and increases submission compliance. Bubble's form elements and conditional states handle draft, editing, and submitted views without extra logic.

• Entry form: Employee selects Project from a filtered dropdown, picks Task, enters hours, adds notes, and saves the entry.
• Draft status: New entries save with a Draft status so employees can edit any entry freely before weekly submission occurs.
• Daily grid view: A repeating group shows Monday through Friday as rows with project entries and hour totals per day.
• Weekly total: Bubble's sum function aggregates all entry hours for the week and displays it next to the submit button.
• Project filter: The Project dropdown only shows active projects the logged-in employee is assigned to, reducing wrong allocations.
• Billable toggle: Each entry has a billable checkbox, defaulting based on the selected Project's billing setting automatically.

Employees receive a reminder notification mid-week if they have fewer than a minimum number of hours logged for the period.

How Do You Build Timesheet Approval Workflows in Bubble?

Submitting a timesheet triggers a backend workflow that creates an ApprovalRecord, notifies the manager, and locks all entries for the period against further editing.

Bubble's access control and privacy rules ensure managers can only view and act on timesheets from their direct reports, not the whole organization.

• Submit trigger: Clicking submit changes all Draft entries for the week to Submitted status and creates one ApprovalRecord.
• Manager notification: The workflow reads the Employee's manager and sends an email or in-app alert with the timesheet link.
• Manager review view: A dedicated page shows the manager each entry grouped by project with hours and notes displayed clearly.
• Approve action: Approval updates the ApprovalRecord status to Approved and locks all linked TimesheetEntry records immediately.
• Reject action: Rejection updates the ApprovalRecord with a comment and returns entries to Draft status for employee correction.
• Locked indicator: Approved timesheets display a locked badge; no edits are possible unless an admin explicitly unlocks the record.

Multi-step approval, such as manager then finance review, is configurable by adding a second ApprovalRecord stage to the same workflow.

How Do You Build Timesheet Reporting and Billing Export in Bubble?

Reporting pages query approved TimesheetEntry records filtered by project, client, or period, displaying billable and non-billable hour splits with one-click CSV export.

Finance teams need period-bound, project-level data. Bubble's repeating groups and aggregate functions produce accurate summaries without external reporting tools.

• Project summary report: Groups approved entries by project, showing total hours, billable hours, and billing amount for the period.
• Client summary report: Rolls project totals up to client level, giving a single billable amount per client per billing period.
• Billable vs non-billable: Each report row shows the split clearly so invoice amounts and internal cost allocations are separated.
• Employee utilization: A separate view shows hours logged per employee against their expected hours for performance visibility.
• CSV export: A workflow converts the filtered report data to CSV and downloads it for upload into billing or payroll systems.

Saved filter presets let finance and billing teams run consistent reports each period without reconfiguring project and date selections.

How Much Does It Cost to Build a Timesheet App on Bubble?

A Bubble timesheet app costs between $14k and $40k depending on scope, with MVP builds covering time entry, basic approval, and CSV export.

Bubble's plan pricing adds a recurring platform cost of $32 to $349 per month depending on the plan tier your team requires.

• MVP scope: Covers time entry form, project and task selection, single-step approval, and a basic weekly summary export.
• Full build scope: Adds billable vs non-billable reporting, client summary views, utilization dashboard, and multi-step approvals.
• Bubble plan cost: A professional services firm using this daily will typically need the Growth plan at $119 per month minimum.
• Maintenance budget: Set aside 10 to 15 percent of build cost per year for new project types, rate changes, and integrations.

Build cost is typically recovered within the first year through reduced billing errors and faster invoice turnaround after approval.

What Are the Limitations of Building a Timesheet App on Bubble?

Bubble handles structured timesheet workflows well, but automatic time capture from calendars or IDEs, real-time billing system push, and complex overtime engines have genuine constraints.

Identifying these limits before scoping ensures you build what Bubble handles well and plan integrations or workarounds for the edge cases.

• Automatic time capture: Pulling time data automatically from Google Calendar, Jira, or IDEs requires third-party integrations with added cost.
• Real-time billing push: Pushing approved hours directly to billing platforms like QuickBooks in real time needs API plugins that add fragility.
• Overtime rule engines: Jurisdiction-specific overtime calculations with multiple thresholds and exemptions push Bubble's workflow logic to its limits.
• Large dataset queries: Reporting across years of entry records with many projects can slow repeating group loads at scale.

Review Bubble's native capabilities and limitations and how Bubble scales under load before scoping reporting requirements. For firms needing direct accounting system integration from launch, other platforms worth considering may reduce integration complexity.

Bubble covers the full timesheet workflow reliably for project-based businesses. Time entry, project allocation, manager approval, and billing exports are all buildable without custom code at a fraction of enterprise timesheet software costs.

Getting the data model right before writing any workflows is the single most important step. A well-structured Bubble timesheet app scales with your client base and adapts quickly when billing rules or project structures change.
