Client Data Protected

Client names, engagement details, and billing information encrypted with keys only you control.

Precision Billing

Track time in tenths of an hour (6-minute increments). The standard for professional services billing.

Professional Exports

PDF invoices, Excel reports, CSV for practice management. Export to QuickBooks, Xero, or any system.

The Problem

Your Time Entries Reveal Sensitive Information

Every entry in your timesheet contains client intelligence:

Client names — Who is preparing for audit, facing tax issues, seeking valuation
Project descriptions — "IRS audit defense," "M&A due diligence," "estate planning"
Time patterns — Heavy billing suggests complex situations
Billing rates — Reveals engagement scope and client tier

"A breach of your time tracking system is a breach of client confidentiality. Names of clients receiving tax audit defense, M&A advisory, or estate planning services are highly sensitive. Tenths encrypts this data with keys only you control."

The Solution

Meeting Your Ethical Obligations

AICPA Code of Professional Conduct requires CPAs to maintain confidentiality of client information. Many state boards have similar requirements.

Most cloud-based time tracking stores your data in plaintext on their servers. They promise confidentiality through policies. But policies can be changed, servers can be breached, and employees can access data.

The Tenths Approach: End-to-end encryption means we cannot access your data — it's encrypted before leaving your device. This isn't a policy; it's mathematics.

How Accountants Use Tenths

Solo Practitioner — Tax Practice

"I have 200+ tax clients and need to track time for the few that are hourly. I can't afford enterprise software, but I need client data protected."

Solution: Create hourly clients in Tenths. Track their time during tax season. Export PDF invoices monthly. Your entire client list stays encrypted — even Tenths can't see who you work for.

Small Firm — Multiple Partners

"Our 5-person firm needs individual time tracking but wants to keep client information confidential across personal devices."

Solution: Each team member uses Tenths on their own device with their own encryption keys. Export time to your practice management system for firm-wide billing.

Financial Advisor — Hourly Planning

"I charge hourly for financial planning work. My clients include high-net-worth individuals who expect discretion."

Solution: Track planning session time in Tenths. Client names are encrypted — even "HNW Planning Client" entries are protected. Export professional invoices that maintain client dignity.

Frequently Asked Questions

Can I import existing client data?

Tenths doesn't have CSV import because that would require us to process your unencrypted data. Start fresh with new clients, or manually add your hourly clients.

What about firm-wide reporting?

Each person exports their time. Aggregate in your practice management system. We don't have multi-user features because that would require us to access your data.

Is this compliant with professional standards?

Tenths' E2EE architecture supports confidentiality requirements. Data is encrypted with keys only you control. We recommend consulting with your state board for specific requirements.

Can I track non-billable time?

Yes. Create a "Firm Administration" client for non-billable work. Track professional development, marketing, admin time — all encrypted like client work.

What happens during an audit of my practice?

You control your data. Export any records you need to provide. Auditors would access your exports, not your live Tenths data.
