Track Billable Time, Send Clean Invoices
Log billable hours by client and project, see what is still uninvoiced, and turn it into an auto-numbered PDF invoice — kept apart from the clock hours your timesheets and payroll use.
See Worklog In Action
Track billable hours against clients and projects with rates applied automatically, then turn uninvoiced entries into an auto-numbered PDF invoice and email it to the client.
What Worklog Helps You Do
Log Billable Hours
Log hours, or a start and end time, for the day you worked. Tag each entry with a client and project, mark it billable or non-billable, and describe the work.
Organize By Project
Projects group the hours for a single engagement and roll up their own hours and earnings. Give a project its own default rate, and keep it private or share it with the team.
Manage Clients
Client records hold contact and billing details, roll up hours and earnings, and show what is still uninvoiced. Filter entries by client to see the engagement.
Fill In The Rate
A billable entry takes the client's default rate, then the project's, then the company default — or the rate you type on the entry.
Generate Invoices
Turn a client's uninvoiced entries into an auto-numbered invoice with a Net-30 due date and your company details. Download the PDF or email it to the client.
See Your Hours
Hours, billable hours, and amounts by period, with entries filtered by project, client, billable status, and date range — and a CSV export.
Built For Services Teams Inside A Bigger Workspace
From Time Entry To Invoice In One App
Worklog covers the full loop — time entry, project rollup, client billing, and invoice generation. Uninvoiced hours become a clean PDF invoice, with project and client context preserved.
- Hours or start and end — log time the way the day worked, not the tool.
- Project and client tagging — every entry organized for billing and reporting.
- Invoice lifecycle — draft, sent, paid, or cancelled, with a reminder when one goes overdue.
- Email or PDF — send invoices from the app, or export and route through finance.
Billing Hours Kept Apart From Pay Hours
What a client is billed for is not what payroll pays. Worklog keeps billable client time on its own, so an invoice never changes a timesheet and a timesheet correction never changes an invoice.
- Billable vs. non-billable — only billable entries reach an invoice.
- Weekly summary — an optional Monday email of last week's hours, billed amount, and top projects.
- Missing-day reminders — an optional nudge when a workday has no time logged.
- Admin rules — require a project, client, or description, and cap the hours one entry may carry.
Worklog In Practice
A practical scope check: what the app covers, which controls matter, and the workflows teams usually run first.
Core workflow
Log billable and non-billable time entries with project and client assignment.
Controls that matter
Reporting & Export includes Dashboard stats: hours, billable hours, amounts by period and Filter entries by project, client, billable status, date range.
Scope and specs
Useful specs: Max hours per single entry: 24 (admin-configurable); Invoice number format: INV-YYYY-#### (auto-generated); Supported export formats: CSV, PDF (invoices).
Daily time logging
Log time entries at the end of each day with work date, hours, project, client, and a description of work performed.
Client billing
Track billable hours at specific hourly rates, then generate an invoice that rolls up a client's uninvoiced time entries.
Project cost tracking
Assign time entries to projects to see your hours and earnings per project, and give chosen admins a read-only view of everyone's entries.
Connected To The Rest Of MangoApps
→ Timesheets
Timesheets hold the clock hours payroll pays; Worklog holds the client hours you bill. Run both in one platform, under one sign-on, without mixing the two.
→ Tasks
Plan deliverables and assignments in Tasks, and log the client time spent on them in Worklog — both in the same platform.
→ Time & Attendance
Attendance records when people clock in and out; Worklog records which clients and projects their billable time went to.
→ Workspaces
Run each engagement's discussions, files, and decisions in a workspace, beside the Worklog project that tracks its billable time.
→ Mobile
Log, edit, and review time entries, projects, and invoices from the MangoApps mobile app team members already use.
REPLACES POINT TOOLS
One billable-hours tracker instead of a separate tool the partners hate
Services teams typically run a separate Toggl, Harvest, or Clockify that nobody fills in until invoicing day. Worklog tracks billable time inside the same platform the team already lives in — with an optional reminder for days left empty, so logging is not a Friday-afternoon archaeology project.
Toggl Track
Time tracker for project teams
- Time entries sit in the platform the team already signs in to — not a parallel Toggl account
- One per-employee Frontline Operations suite license covers Worklog plus Timesheets, Time & Attendance, Tasks, and Shifts & Scheduling
- Replaces a vendor with a feature inside the employee platform you already run
Harvest
Time tracking and invoicing for services
- Client, project, and company default rates fill in each billable entry — no rate typed twice
- One identity perimeter across billable hours, payroll hours, and the rest of the workforce
- Mobile capture on the branded app team members already open for chat — not a separate Harvest mobile app
RescueTime
Automatic time tracking and productivity analytics
- Captures billable time against client work, not just generic categories — output that ties to invoicing, not a wellness score
- Worklog AI reports hours, billable breakdowns, and uninvoiced work on request — not just app-category breakdowns
- One sign-on — no separate productivity-tool data residency review
Clockify
Free time tracker for teams
- Comes with client and project rollups and invoicing — not just a timer to fill out twice a week
- Per-employee suite license covers it inside the same Frontline Operations bundle as Timesheets, Time & Attendance, and Tasks
- Billable client time and payroll hours in one platform — not Clockify plus a spreadsheet plus your HRIS
PLATFORM ADVANTAGE
Worklog inherits everything else MangoApps already does
A standalone time tracker has to build, buy, or integrate each of these. Worklog gets them for free because the platform already runs them.
Identity & SSO
SAML/OIDC SSO, MFA, and SCIM provisioning already cover every consultant and engineer logging time. No separate Worklog identity to maintain.
Default rates
Set a default rate on each client and project, and a company default behind them — every billable entry fills in the right one.
Tasks & Workspaces
Deliverables live in Tasks and decisions in Workspaces, in the same platform where Worklog tracks the billable time.
Private or shared
Each project and client is private to its owner or shared with the team, and exports include rates only when an admin says so.
Mobile app
Team members log and edit time, and check projects and invoices, from the branded mobile app they already open for chat.
Reminders & summaries
Optional reminders for days with no time logged, a weekly summary email of each person's hours, and an automatic reminder when an invoice goes overdue.
INDUSTRY FIT
Built for services and project businesses where every hour is revenue
Worklog matters where unrecorded time is unrecognized revenue and write-offs eat margin one missing entry at a time.
Professional Services
Consultants and engineers log billable time against each client and project — hours and earnings roll up as they go.
Legal
Matter-level billable hours captured against each client, with private projects for confidential matters and invoices numbered automatically.
Accounting
Client and engagement-level time captured per partner and staff, with uninvoiced work visible on each client before month end.
Marketing & Creative Agencies
Account, project, and retainer time tracked per client — hours per project show over-servicing before it eats into margin.
Technology Consulting
Engineer time tagged to client projects, billable or not, with each project's hours and earnings rolling up in one place.
Architecture & Engineering
Project time captured per client and project, with per-project rates and numbered invoices to match billing and contract reviews.
WHY MANGOAPPS WINS
One platform beats a stack of point solutions on every axis
The argument finance, security, ops, and partners all share — and the one a time-tracker point tool structurally cannot answer.
Cheaper than the stack
One per-employee suite license replaces Toggl or Harvest plus the timesheet, time-clock, and task tools layered around them.
More secure
One identity perimeter and one set of roles and permissions across every time entry and invoice. Nothing for security or clients to re-certify.
Easier to deploy
Already deployed if you have MangoApps. Add your clients and projects, set their default rates, and book your first billable hours the same day.
Easier to use
Capture time in the same app the team uses for chat and tasks — on the phone or the desktop, instead of a Friday data-entry session.
Easier to manage
Admins set the default rate, currency, required fields, invoice company details, and export options from one settings page.
Easier to extend
Import entries from CSV, export them back out, and turn on reminders for empty days; you are reminded automatically when an invoice goes overdue.
AI is actually better
Worklog AI reports hours, billable breakdowns, and uninvoiced work against the live entries, and drafts invoices you review — governed by the same permission model that protects every other client and workforce record.
Ask Questions With Worklog AI
Worklog has a paired AI agent for the questions you'd otherwise pull a spreadsheet to answer. It uses the same records and respects the same permissions as the app.
Worklog AI
Report hours for today, this week, last month, or any dates — with billable breakdown, invoice status, and uninvoiced work surfaced for review. It can also log, edit, or delete an entry, draft an invoice, and mark one sent, paid, or cancelled, each after you confirm.

Our frontline employees determine whether or not a customer is going to come back to the store. In order to provide a great customer experience, you’ve got to provide a great experience to your team members. If you’re not engaging with them, it’s less likely that they’re going to deliver on this, simply because they haven’t been enabled and supported to do it.

Frequently Asked Questions
Worklog focuses on billable-time tracking and invoicing — projects, clients, hours, rates, and invoices. For deliverables, deadlines, and assignments, pair it with Tasks; time entries are tagged by client and project, not to individual tasks.
Each client and project can carry a default rate, behind a company-wide default. A billable entry takes the rate typed on it, else the client's, then the project's, then the company default.
No, on purpose. Worklog is billable client time; Timesheets hold the clock hours payroll pays. Keeping them apart means an invoice never changes anyone's pay.
A client's uninvoiced billable entries roll up into an auto-numbered invoice — line items, totals, a Net-30 due date, and your company details. Download it as a PDF or email it to the client from Worklog, then mark it sent or paid.
Yes. Time entries flag as billable or non-billable. Non-billable time still counts in your hours and exports but is excluded from invoice generation — useful for tracking internal project effort.
The agent reports hours for today, this week, last month, or any dates with a billable breakdown; surfaces invoices and uninvoiced work; and can log, edit, or delete time entries, draft an invoice, and mark an invoice sent, paid, or cancelled — each only after you confirm. It never emails a client. See the agent page for the full capability list.
