Five key facts about accounting software for architects, one pattern: the market is split between general-purpose tools that everyone knows and specialized platforms that are built for project-based billing.

Metric Value
Number of architecture firms in US 27,000+
Average firm size (employees) 10
Most popular accounting software overall QuickBooks (40% share)
Fastest growing accounting software for architects Xero
Percentage of firms using cloud accounting 60%

The pattern: QuickBooks still dominates by sheer volume, but the fastest-growing segment is cloud-native, project-focused tools.

What is the best accounting software for architects?

There’s no single “best” — the right choice depends on firm size, billing complexity, and whether you need integrated project management. Here are the top contenders, each with a distinct sweet spot.

Top accounting software for architecture firms

Three options, one trade-off: depth of integration versus simplicity of setup.

Feature Xero Deltek Ajera NetSuite
Starting price (monthly) $25 (Early tier) Not publicly available (quote required) Custom quote (typically $999+)
Project-based billing Yes Yes (core feature) Yes (via SuiteProjects)
Time tracking Third-party integrations Built-in Built-in
Multi-currency Yes Yes Yes
Best for firm size 1-50 employees 20-500 employees 100+ employees

The trade-off: Xero wins on price and ease of use; Deltek wins on depth; NetSuite is for enterprises that need a full ERP.

User reviews and community recommendations

On Reddit, solo architects often recommend Xero for its clean interface and bank reconciliation, while larger firms point to Deltek for comprehensive project accounting (Reddit r/Architects community discussion).

The upshot

For a 10-person firm, Xero’s $55/month Growing plan covers project tracking and invoicing with minimal setup. Deltek Ajera delivers more but requires consultant-led implementation, which can be a barrier for small teams (Factor App architecture business blog).

Bottom line: The implication: The best choice matches your billing workflow, not your marketing brochure. Xero gives fast start; Deltek gives control; NetSuite gives scale — but only if needed.

What software do most architects use?

Architects rely on a stack of tools, not just one. The design side is dominated by a few industry standards, while the business side is more fragmented.

General software categories architects rely on

Design software vs. business management tools

Design software like Revit and AutoCAD are non-negotiable for production. But the business side — accounting, billing, payroll — is often handled with separate tools that don’t talk to each other. The trend is toward integration: cloud-based platforms that connect project hours to invoices automatically.

Industry preferences and trends

Cloud-based solutions are now adopted by over 60% of firms, up from roughly 40% five years ago (Business Accounting UK resource). For firms in New Zealand, managing finances also involves understanding start up business loans and IRD bank account number requirements — both of which are easier to track when accounting software is project-aware.

The pattern: The line between design and business tools is blurring. Firms that adopt a unified platform save hours of manual data entry each month.

What Software Do Architects Use?

This question usually comes from someone outside the profession who sees the finished building but not the stack of software behind it. The answer is a layered toolkit.

Design and drafting software

Accounting and project management platforms

On the financial side, QuickBooks holds the broadest user base, but Xero is growing fastest among architects. Deltek Ajera is the established choice for medium-to-large firms that need integrated project accounting (Deltek enterprise software for project-based firms).

Collaboration and rendering tools

Collaboration platforms like BIM 360, Bluebeam, and rendering tools like V-Ray and Enscape round out the stack. The key takeaway: accounting software is just one piece of a larger puzzle — but it’s the piece that keeps the firm solvent.

Why this matters

A firm using Revit for design but QuickBooks for accounting will spend extra hours reconciling project budgets. The firms that adopt a platform connecting design hours to billing — like Deltek Ajera — reduce that overhead by an estimated 30% (Factor App architecture business blog).

The implication: The software stack is a chain. If the accounting link is weak, the whole firm feels it.

What is the best software for construction accounting?

Construction accounting adds layers: job costing, change orders, subcontractor payments, and prevailing wage compliance. The tools that serve architects don’t always cover construction’s needs.

Construction-specific accounting needs

  • Job costing – track costs by project down to the line item.
  • Change order management – handle scope changes without breaking the budget.
  • Subcontractor payments – manage 1099s and lien waivers.
  • Prevailing wage compliance – required for public projects.

Top contenders: Sage, Procore, and QuickBooks

Three options, one trade-off: breadth versus depth.

Platform Best for Pricing Construction-specific features
Sage 100 Contractor Small to mid-size contractors Starts around $150/month Job costing, lien waivers, certified payroll
Procore Mid-size to large contractors Custom quote (typically $500+/month) Full project management, RFIs, submittals, financials
QuickBooks Enterprise Small contractors $1,340/year (plus payroll add-on) Job costing add-on, third-party apps

The catch: Procore is more than accounting — it’s a full construction management platform. QuickBooks works for small contractors but lacks native change order management.

Integration with project management

Many architecture firms that also do construction management need a tool that bridges design and build. Deltek Ajera and Xero both offer integrations with Procore and Sage, but the setup requires careful mapping of cost codes (Software Advice software comparison platform).

The pattern: For a design-build firm, accounting software needs to talk to construction management. Sage and Procore do that out of the box; QuickBooks requires middleware.

What are people replacing QuickBooks with?

QuickBooks has been the default for decades, but dissatisfaction is growing. Users cite complex pricing, feature bloat, and poor customer support as reasons for leaving (Reddit r/Architects community discussion).

Reasons for switching from QuickBooks

  • Pricing complexity – multiple tiers, add-ons, and payroll costs that escalate quickly.
  • Feature bloat – many features that a small architecture firm never uses.
  • Customer support – long wait times and limited help for niche issues like project-based billing.

Top alternatives: Xero, FreshBooks, and Zoho Books

Xero is the most common replacement due to stronger project tracking and multi-currency support. FreshBooks and Zoho Books appeal to freelancers and very small firms (1-5 people) with simpler needs (Business Accounting UK resource).

Industry-specific solutions gaining traction

Deltek Ajera and BQE Core are growing in architecture-specific segments. These platforms manage the full project lifecycle from proposal to closeout, which is why firms with 20+ employees are increasingly adopting them (Factor App architecture business blog).

The catch

Switching from QuickBooks to Xero or Deltek is not a weekend project. Data migration, chart of accounts mapping, and staff training can take 2-4 weeks. But firms that do it report a 20-30% reduction in month-end close time (Software Connect industry software roundup).

The trade-off: The pain of switching is real, but the long-term gain in efficiency is substantial for firms that outgrow QuickBooks.

Do architects still use CAD?

Yes — but the role of CAD has changed. AutoCAD remains essential for 2D drafting, especially for renovations, small projects, and legacy workflows. However, BIM (Revit) has overtaken CAD in many large firms for new construction (Software Advice software comparison platform).

Current state of CAD in architecture

  • AutoCAD – still widely used for 2D drafting, details, and documentation.
  • Revit – dominant for BIM, especially in projects over 10,000 sq ft.
  • Rhino + Grasshopper – used for complex geometry and parametric design.

Shift toward BIM and 3D modeling

BIM is now standard in commercial architecture. The shift is driven by client demand for clash detection, quantity takeoffs, and lifecycle management. Accounting software that integrates with BIM tools — like Deltek Ajera’s API — allows cost data to flow directly from the model (Deltek enterprise software for project-based firms).

Is CAD still taught in schools?

Architecture schools still teach AutoCAD, but the curriculum increasingly focuses on Revit and Rhino. Graduates are expected to know BIM workflows. The implication for accounting software: if your firm uses Revit, look for a platform that can import project data from the model.

The pattern: CAD is not dead — it’s one tool in a larger ecosystem. The firms that survive integrate design data with financial data.

What features should architects look for in accounting software?

Not all features are equally important. For architecture firms, the top five are:

  1. Project-based billing – ability to bill by phase, by task, or by percent complete.
  2. Time tracking integrated with billing – so hours log directly into invoices.
  3. Multi-currency support – for firms working internationally.
  4. Job costing – track actual costs vs. budget per project.
  5. Integration with design tools – at least export/import of project data.

Xero covers all five for small to mid-size firms. Deltek Ajera adds deeper cost forecasting and resource management. QuickBooks Online with the Projects add-on covers the basics but lacks the seamless integration that a dedicated architecture platform offers (Business Accounting UK resource).

What to watch

If your firm has more than 20 employees and manages multiple projects simultaneously, the lack of built-in resource scheduling in QuickBooks becomes a bottleneck. That’s when Deltek Ajera starts to pay for itself.

The implication: The feature you think you need today (e.g., pretty invoices) may not be the one you need tomorrow (e.g., job cost variance reports). Choose a platform that scales with your project complexity.

Frequently asked questions

What features should I look for in accounting software for my architecture firm?

Look for project-based billing, integrated time tracking, job costing, multi-currency, and integration with design tools. Xero and Deltek Ajera both offer these, but Deltek is more comprehensive for larger firms.

Is QuickBooks enough for an architecture firm?

For a solo practitioner or very small firm, QuickBooks Online with the Projects add-on can work. But as you grow past 5-10 employees, the lack of built-in project accounting becomes a limitation. Many firms switch to Xero or Deltek at that point.

How much does Xero cost for architects?

Xero’s US pricing starts at $25/month for the Early plan, $55/month for Growing, and $90/month for Established. The Growing plan ($55/month) is the most common for small architecture firms because it includes project tracking and invoicing (Xero pricing page).

Can I use free accounting software like Wave for my firm?

Wave is free for basic accounting, but it lacks project-based billing, time tracking, and multi-currency support. It may work for a sole practitioner with very simple needs, but most growing firms find it insufficient.

What is the difference between project management and accounting software?

Project management software (e.g., Asana, Monograph) tracks tasks, deadlines, and deliverables. Accounting software tracks money. Some platforms like Deltek Ajera and Xero combine both, but most firms use separate tools and integrate them via API.

Do I need separate software for project billing and accounting?

Not necessarily. Xero and Deltek Ajera both offer project billing within the accounting platform. However, if you use a specialized project management tool like Monograph, you may need to export data and import it into your accounting software each month.

How do I migrate from QuickBooks to Xero?

Xero offers a guided migration tool that imports your chart of accounts, customers, vendors, and historical transactions. The process typically takes 1-2 weeks, including data mapping and testing. Many firms hire a Xero-certified accountant to assist.

For architects in New Zealand, managing finances also involves understanding start up business loans and IRD bank account number requirements — both of which are easier to track when accounting software is project-aware.

The bottom line: Accounting software for architects is no longer a choice between QuickBooks and nothing. The market now offers specialized tools that match the way architects actually work — by project, by phase, by the hour. For small firms, Xero provides the fastest path to clean, project-based books. For mid-size firms, Deltek Ajera delivers the depth needed to manage multiple projects profitably. The cost of sticking with a generic tool is hidden in unbilled hours and inaccurate job costs. For the 10-person firm billing $1.2 million a year, that hidden cost can easily exceed $10,000 annually. The choice is clear: pick a platform that treats your projects as the financial unit they are, or keep piecing together a solution that doesn’t.
