Why Don’t Employees Log Time Consistently at Interior Design Firms?

TL;DR: Employees skip or split time logging because they’re forced to enter hours in two different systems, one for client billing and one for payroll. That extra step creates friction, and firms that grow up on disconnected tools like Harvest, Excel, ADP, and QuickBooks tend to stick with them out of habit even after adopting project management software. Studio Designer solves this by making time entry a single action that feeds both billing and payroll, with cloning to duplicate entries instead of retyping them. 

Key Takeaways 

• The main cause of inconsistent time logging is duplicate entry across separate billing and payroll platforms. 
• Firms often keep legacy tools like Harvest, Excel, ADP, or QuickBooks even after adopting project management software, simply because teams are comfortable with them. 
• Consistent time logging directly affects client billing accuracy, profit margin visibility, and staffing decisions. 
• Studio Designer combines billing and payroll time entry into one action, and lets employees clone entries instead of re-entering them. 
• Unbillable hours matter too. Hourly employees still need to log those hours to get paid, even when they’re not tied to a client invoice. 

What Stops Employees From Logging Time Consistently? 

The most common reason is that employees are asked to log time twice, once in a platform that tracks client billing and once in a system that handles payroll. A designer might log hours in Harvest so a client gets billed correctly, then log the same hours again in ADP or QuickBooks so payroll runs correctly. Nobody wants to do the same task twice, so entries get delayed, shortened, or skipped altogether. 

This split usually isn’t a deliberate choice. It’s a byproduct of how design firms grow. Most start out with whatever tools are on hand: a spreadsheet for hours, a separate app for invoicing, a payroll processor that doesn’t talk to either one. As the firm scales and adds a proper project management platform, the old habits don’t disappear. Teams are comfortable in Harvest or Excel and switching feels like extra work even when the new system can handle everything. The result is a firm running on disconnected systems long after it’s outgrown them, which makes it harder to see where productivity is actually coming from. 

How Does Studio Designer Fix Duplicate Time Entry? 

Studio Designer treats time tracking as a single entry that serves both purposes at once. When an employee logs hours in Studio Designer, that entry powers client billing and payroll from the same record, so there’s no second system to update and no reason to skip it. 

Studio Designer also supports cloning and duplication of time entries. If someone works similar tasks across multiple days or projects, they can duplicate a prior entry instead of typing it in from scratch. This removes one of the biggest complaints about time tracking: the redundant, repetitive data entry that makes people put it off. 

Hourly employees benefit from this setup even when their work isn’t billable. Non-billable hours still need to be logged so those employees get paid correctly, and a single-entry system captures both billable and non-billable time without requiring a separate payroll tool. 

Why Does Consistent Time Logging Actually Matter? 

Inconsistent time logging isn’t just an administrative annoyance. It affects three things a design firm needs to run profitably. 

Accurate client billing. If time isn’t logged, it doesn’t get billed. A firm that under-logs hours is effectively working for free on that portion of the project. 

Profit margin visibility. Time logs show how much of a project’s work was billable versus non-billable. Without that data, a firm can’t tell whether a project was actually profitable or just looked busy. 

Staffing and growth decisions. Principals and accountants rely on time data to decide whether to hire, restructure teams, or change project scope. If a firm only billed for half the hours actually worked on a project, that’s a signal worth investigating, but only if the data exists to surface it in the first place. 

Without consistent logging, none of these decisions have a reliable foundation. A principal asking “why did we only bill 50% of the time spent on this project?” needs accurate time data to even ask the question, let alone answer it. 

Studio Designer vs. Harvest, ADP, and QuickBooks for Time Tracking 

Harvest, ADP, and QuickBooks are built to do one job well: Harvest for time and invoicing, ADP for payroll, QuickBooks for accounting. None of them are built specifically for interior design workflows, and none of them connect billing and payroll in a single entry. Studio Designer is built for design firms specifically, which is why it can combine both functions where general-purpose tools can’t. 

Frequently Asked Questions 

Why do employees log time in two different apps?

Employees typically log time twice because their firm uses one platform for client billing (like Harvest) and a separate platform for payroll (like ADP or QuickBooks). Each system requires its own entry, so the same hours get typed in twice.

What is the biggest reason design firms keep disconnected time tracking systems?

Comfort and inertia. Teams that started on tools like Excel or Harvest often keep using them even after the firm adopts project management software, because switching feels like extra work in the short term.

Does Studio Designer replace Harvest, ADP, or QuickBooks for time tracking?

Studio Designer replaces the need to log time in a separate billing and payroll tool by handling both from a single time entry, built specifically for interior design firms.

Do hourly employees need to log unbillable time?

Yes. Hourly employees need to log all hours worked, including non-billable time, so they’re paid correctly. A single-entry system captures both billable and non-billable hours without requiring a second tool. 

How does inconsistent time logging affect profit margins?

It hides the true ratio of billable to non-billable work on a project. Without accurate logs, a firm can’t tell whether a project was actually profitable or where time was lost.
