Time Tracking for Architects: Software vs Spreadsheets

Architecture practices thrive on creative precision, but when it comes to operational management, tracking time often falls into a grey area. Whether designing a boutique residential space or managing a multi-phase commercial development, how your practice logs hours directly impacts billable accuracy, project margins, and business growth.

Firms generally track time using one of four main approaches: paper timesheets, Excel spreadsheets, generic SaaS time trackers, and architect-focused software. Each method carries specific trade-offs across billing recovery, reporting, and workflow integration.

1. Paper Timesheets

  • The Pitch: Zero technical barrier to entry.
  • The Reality: Significant unbilled time and high administrative friction.

Paper logs rely entirely on end-of-week memory recall. Architects frequently lose track of hours spent on quick design revisions, site visits, or unexpected client calls.

  • Accuracy & Billing: Un-captured hours lead to “leakage” time spent working that never makes it onto an invoice.
  • Reporting & Integrations: Manual data entry requires administrators to rekey handwritten numbers into spreadsheets or accounting tools, wasting hours and introducing human error.

2. Excel Spreadsheets

  • The Pitch: Low initial cost, highly customizable, familiar to everyone.
  • The Reality: Multi-file management creates broken formulas and zero real-time visibility.

Spreadsheets are the default choice for early-stage practices. However, as team sizes grow, managing dozens of individual files becomes unsustainable.

  • Accuracy: Version control issues mean project managers frequently work off outdated files.
  • Reporting: Aggregating data across multiple projects or staff members to evaluate profitability requires complex macros and hours of manual labor.
  • Integrations: Spreadsheets operate in a silo. Linking time logged in Excel to accounting tools like Xero or QuickBooks requires ongoing manual imports.

3. Time Tracking Software

  • The Pitch: Easy cloud-based entry, mobile apps, basic reporting.
  • The Reality: Lacks the structural depth needed for complex architectural workflows.

Generic SaaS time trackers work well for simple agency setups, but struggle with the phased, long-term nature of architectural projects.

  • Accuracy: These tools typically track simple time blocks without accounting for sub-tasks, variation requests, or speculative work.
  • Reporting: Generic tools cannot natively break down performance against industry-standard frameworks like RIBA work stages (from Stage 0 Strategic Definition to Stage 7 In Use).
  • Integrations: Basic invoicing links exist, but they often lack the detailed line-item breakdown required for complex fee proposals.

4. Architect-Focused Time Tracking Software

  • The Pitch: Purpose-built workflows designed around project phases, fee forecasting, and industry compliance.
  • The Reality: Accurate billing recovery and automated financial control.

Dedicated software for architects structures time tracking around actual practice workflows rather than generic task lists.

  • Accuracy: Allows teams to log time directly against specific project phases, tasks, and variations, ensuring every design iteration is accounted for.
  • Reporting: Delivers real-time Work in Progress (WIP) visibility and budget-versus-actual tracking. Practices can identify profit margins per phase before a project goes over budget.
  • Integrations: Connects timesheet data directly to accounting engines (like Sage and Xero) and business intelligence tools (like Power BI) to automate invoicing.

The Verdict: Upgrading Your Practice Workflow

While spreadsheets and generic tools might suffice for small, quick-turnaround jobs, growing practices need a system that supports long-term project delivery and protects profitability.

Specialist Software like Coretime bridges the gap between daily time entry and practice performance. Built specifically for time-based professions, Coretime enables architectural practices to log hours against distinct project phases (such as RIBA stages), monitor WIP in real time, and link timesheet data straight to invoicing and accounting tools eliminating double entry and ensuring every billable hour is captured.
