The Timesheet Template That Rolls Up Hours and Flags Over-Budget Projects on a Schedule

Lead: Every professional services firm tracks time. Almost none of them know a project is over budget until the invoice goes out. The timesheet tells you hours were logged. It does not tell you that Project Atlas has burned 142% of its budgeted hours with two deliverables still outstanding — because that requires a rollup formula comparing logged hours to budget, and most timesheet templates are flat grids that do not know what a project budget is.

We analyzed the time tracking templates and tools from Harvest, Toggl, and Airtable. Each one handles time entry well. None of them ship the three features that turn a timesheet into a profitability tool: project-budget rollups, formula-driven over-budget flags, and a weekly digest that tells managers which projects are bleeding before the month-end report.

We built all three into a Baserow template. Free, open source, self-hosted, zero per-seat pricing.

Why most timesheet templates measure effort but not profitability

Time tracking and time management are different problems. Tracking answers "how many hours did we log?" Management answers "are we making money on this project?"

No project budget linkage. The timesheet knows hours. It does not know the budget those hours are burning against. When a consultant logs 8 hours on Monday, the timesheet records 8 hours. It does not record that the project is now at 85% of its budget with 40% of the work remaining.

No over-budget detection. A project crosses its hour budget. Nobody knows until the project manager manually adds up the timesheets, compares them to the contract, and does math that a formula should have done. By then, the damage is done — scope is delivered, hours are spent, and the margin is negative.

No team-level visibility. Most timesheet templates show one person's time entries. Managers need to see total hours across the team, per project, per week. Building that view from individual timesheets requires exporting to Excel and pivoting — every week.

No proactive reporting. The data exists to identify over-budget projects on Tuesday. But nobody sees it until the monthly report, because the timesheet is a logging tool, not a reporting tool. The weekly digest that a project manager needs does not exist.

What the competitors actually give you

Harvest: the right billing integration

Harvest is the standard for time-tracking-to-invoicing. Log time, generate an invoice, send it to the client. The workflow is clean, and the project budget feature is real — you can set an hour or dollar budget per project and see a progress bar. For firms that need time-to-invoice in one tool, Harvest earns its place.

What it costs: $10.80/seat/month. A twenty-person agency pays $216/month. The budget alerts exist but are basic — you get a notification when a project hits a percentage threshold. There is no weekly digest of all projects with their budget status. And the alert is per-project, not per-portfolio — if you manage thirty projects, you manage thirty individual alert settings.

Toggl: the right time entry UX

Toggl has the best time entry experience in the category. One-click timers, browser extensions, mobile apps, and a "track from anywhere" philosophy that minimizes the friction of logging time. For teams where the main problem is getting people to log time at all, Toggl's UX is the right answer.

What it costs: Toggl Track starts at $9/user/month for the Starter plan. Project time estimates exist, but over-budget flagging — the feature that matters for profitability — is in the Premium plan ($18/user/month). A twenty-person team on Premium pays $360/month. And Toggl's reports, while good, are pull-based — you log in and run them. There is no scheduled digest that pushes the answer to your inbox.

Airtable: the right data model

Airtable's timesheet templates separate Time Entries, Projects, and Team Members into linked tables. Rollup fields can sum hours per project, and the structure supports the views a manager needs — hours by person, by project, by week.

What it does not do: connect to budgets or alert anyone. There is no Budget field on the project. There is no formula comparing logged hours to budgeted hours. There are no notifications. The template gives you a place to log time and a correct relational structure. The profitability math is your problem.

The rebuild: timesheets that protect your margins

The Timesheet & Time Tracking template runs on Baserow and connects time entries to project budgets with formula-driven exception detection.

Time entry with project linkage. Every time entry links to a project and a team member. Fields include Date, Hours, Task Description, and Billable (yes/no). The structure is relational — one project has many time entries, one team member has many time entries, and the rollups work in both directions.

Project-budget rollups. Each project has a Budgeted_Hours field. A rollup field sums all time entries linked to that project into Total_Logged_Hours. A formula field calculates Budget_Used_Percent as Total_Logged_Hours / Budgeted_Hours * 100. You see the burn rate on the project row without adding anything up.

Over-budget flag. A formula field evaluates Budget_Used_Percent. When it exceeds your threshold — 80% is the default warning, 100% is the critical flag — the project is marked as over-budget. The flag is a formula that fires the instant the condition is true. No one has to notice. No one has to run a report.

Event-triggered over-budget alert. When a project crosses the over-budget threshold, the project manager gets an email. The alert includes the project name, budgeted hours, logged hours, and the percentage consumed. It fires once per threshold crossing and re-arms automatically — if the budget is increased and the project crosses again later, a new alert fires.

Weekly project digest. A scheduled email goes to managers every Monday morning: all active projects with their budget status, projects in the warning zone (80-100%), projects over budget, and total team utilization for the prior week. This is the weekly profitability review, delivered without logging in.

Working sample data. The template ships with five projects, three team members, and sixty time entries across two weeks. Two projects are deliberately over budget. One is in the warning zone. The formulas and flags demonstrate themselves immediately.

Who this is for

Professional services firms. Consulting, accounting, architecture, engineering — any firm where time is the product. You need to know which projects are profitable before the invoice goes out, not after.

Agency managers. You are juggling client projects with fixed budgets and variable effort. A project that goes 30% over budget erases the margin on two other projects. You need the flag at 80%, not at 130%.

Freelancers and small consultancies. You track time in a spreadsheet because Harvest and Toggl cost $10-18/seat/month and you are one seat. You need project budgets and over-budget alerts, and you need them free.

Any team where time tracking exists but budget visibility does not. If your team logs time religiously and your project managers still get surprised by budget overruns, the problem is not time entry — it is the missing rollup-to-budget connection.

What open source buys you here

Timesheet data is operational data — who worked on what, for how long, and how much it cost. For consulting firms, this data feeds client invoices and internal profitability analysis. It is sensitive, and it is yours.

Self-hosted Baserow means your time data lives on your infrastructure. No SaaS vendor can analyze your utilization patterns or your billing rates. No pricing increase forces a migration. And the over-budget formula is inspectable — your project managers can read the calculation, verify the threshold, and adjust it for projects with different risk tolerances.

Evaluation checklist for any timesheet template

1. Do time entries link to projects with budgets, or is the timesheet a standalone log?
2. Is there a formula that compares logged hours to budgeted hours automatically?
3. When a project crosses its budget, does the project manager get notified or do they find out at month-end?
4. Can you get a weekly summary of all project budget statuses without running a report?
5. What does it cost per seat, and does that price make sense for everyone who should be logging time?
