Choosing the Right Accounting Solution for your Practice
When selecting an accounting solution for your architecture firm, points to consider include:
- The size of your practice: Freelancers vs larger multi-staff firms
- Billing model: Hourly, fixed-fee, or hybrid
- Complexity of projects: Are you managing multiple projects, phases or entities?
- Integration needs: Do you use time-tracking, project management or design tools?
- Growth plans: Will your accounting needs scale as your firm grows?
