Klartab is two opinionated tools built around one idea: do the obvious thing well, then stop.

Klartab Time is a timesheet tool for freelancers who bill by the hour. There's no live timer, no activity tracking, no bloat - just a clean monthly calendar where you log hours per project, export a PDF, and get paid. It handles multiple clients, currencies, and rates without any conversion surprises. Hour caps per work order nudge you before you accidentally over-bill a retainer. Once a month is invoiced, you lock it - server-side, no edits, no surprises.

Klartab Agency is the companion app for staffing agencies and boutique placement shops. Define work orders centrally, invite your contractors, and every submitted timesheet lands in one filtered inbox - defaulted to what's pending. Review with a full time-entry breakdown and a comment thread, approve to lock the period, or reject with a reason so the freelancer can resubmit in place. No invoicing, no payouts - deliberately out of scope.

The two tools work together but don't depend on each other. Use either one in isolation. Connect both, and any freelancer placed through your agency gets Klartab Time at no extra cost.

Both products are EU-hosted (Belgium), GDPR-ready, and built without behavioural advertising. Your data stays yours - and deleting your account is a one-click cascade.

Questions & Answers

As answered by people managing Codility and Klartab.

Why should a person choose your product over its competitors?

Klartab's answer:

Choose Klartab if you want tools that respect your time and your data, without the noise.

  • Radical simplicity โ€” most time-trackers try to do everything: live timers, activity screenshots, integrations, AI insights. Klartab Time does one thing: log hours per project, export a clean report, get paid. No hidden complexity.
  • Privacy-first โ€” EU-hosted (Belgium), GDPR-ready, no behavioural advertising. Your data is never monetised.
  • Fair, transparent pricing โ€” one flat price with no tiers or per-feature upsells. Freelancers placed through a Klartab Agency agency get Klartab Time included at no extra cost.
  • Purpose-built agency workflow โ€” Klartab Agency replaces the spreadsheet-and-email approval loop with a proper submissions inbox, comment threads, approve/reject workflow, and period locking. Competitors either ignore agencies or bundle too much.
  • No lock-in โ€” month-to-month, cancel any time, data stays accessible read-only for 60 days after cancellation.

What makes your product unique?

Klartab's answer:

Klartab is built around a single philosophy: do the obvious thing well, then stop. Unlike bloated all-in-one tools, Klartab offers two deliberately focused products โ€” Klartab Time for freelancers and Klartab Agency for staffing agencies โ€” each solving one problem without scope creep.

  • No live timer, no activity tracking โ€” Klartab Time records totals over an interval, keeping things simple and respectful of your privacy.
  • EU-hosted and GDPR-ready โ€” all data lives in europe-west1 (Belgium); no behavioural advertising, and your data stays yours.
  • Tight integration between the two tools โ€” freelancers placed through a Klartab Agency get Klartab Time at no extra cost, with a clean submission and approval workflow.
  • One flat price per tool, no tiers, no upsells โ€” โ‚ฌ10/month for Klartab Time; โ‚ฌ100/month + โ‚ฌ5/active seat for Klartab Agency.

How would you describe the primary audience of your product?

Klartab's answer:

Klartab serves two distinct audiences that often work together:

Freelancers (Klartab Time) Independent contractors who bill multiple clients at different rates and currencies. Specifically: - Mixed-client freelancers who need clean per-project PDF reports at month-end without manual spreadsheet work. - Retainer-heavy contractors on fixed-hour engagements who need cap tracking to avoid over-billing. - Freelancers placed through staffing agencies who need a simple way to submit timesheets for approval.

Staffing & Placement Agencies (Klartab Agency) Boutique agencies (typically 5โ€“30 contractors) that place freelancers with end clients and need to manage the time-approval workflow centrally. This includes working agency owners who both manage their teamโ€™s submissions and log their own hours as a placed freelancer.

What's the story behind your product?

Klartab's answer:

Klartab was built out of a frustration with tools that do too much. The founding philosophy is simple: identify the one obvious thing a tool should do, do it well, and stop there.

Klartab Time started as a timesheet tool for freelancers who were tired of live timers, activity tracking, and surveillance-style software. The goal was a clean, manual log โ€” hours per project, your rate, a PDF for the client โ€” without any of the noise.

Klartab Agency followed as the natural companion for the agencies that place those freelancers. Instead of chasing submissions over email and reconciling spreadsheets, agencies get a purpose-built inbox with approve/reject workflows, comment threads, and period locking.

Both products share the same values: EU-hosted, GDPR-ready, no behavioural advertising, transparent flat pricing, and a deliberate refusal to expand scope beyond whatโ€™s needed. The Klartab suite is built for people who want software that gets out of the way.

Which are the primary technologies used for building your product?

Klartab's answer:

Klartab is built on Google Cloud infrastructure:

  • Cloud Run โ€” for serverless container hosting
  • Cloud SQL โ€” for the relational database (PostgreSQL), hosted in europe-west1 (Belgium)
  • Firebase Authentication โ€” for user auth
  • Stripe โ€” for billing and payments (with Stripe Tax for EU VAT handling)

The web app is fully responsive and works well on mobile browsers. Native iOS and Android apps are on the roadmap.

Who are some of the biggest customers of your product?

Klartab's answer:

Klartab is an early-stage product and does not publicly list named customers. The typical customers are:

  • Independent freelancers billing multiple clients across different currencies
  • Retainer-heavy contractors managing fixed-hour engagements
  • Boutique staffing and placement agencies (typically 5โ€“30 contractors) that need a structured approval workflow for timesheet submissions
