Seventy-four days. That's how long architecture firms wait on average between sending an invoice and seeing cash hit the bank, according to recent industry data on payment wait times. During that month-and-a-half stretch, you're still cutting payroll, paying consultants, and fronting project expenses; often without knowing whether every billable hour or reimbursable cost even made it onto the invoice.
Those leaks add up fast. Late invoices, forgotten change orders, and error-ridden spreadsheets quietly drain profit from otherwise healthy projects.
The fix is mostly procedural, not philosophical. Firms that replace manual billing with industry-specific software typically capture work more accurately and bill it faster. Workshop/APD saw 50% efficiency gains within their first year. Faster billing cycles improve cash flow, but the bigger win is clarity: when every hour and expense is tracked in real time, you finally see which phases, teams, and clients are worth the effort.
Each tool here tackles the pain points you and I face daily: time tracking that feeds directly into invoices, expense capture that doesn't require detective work, automated reminders so you stop playing collections agent, and project-based billing that mirrors how architects actually work.
Best Overall: Monograph
If you're tired of juggling spreadsheets, invoices, and consultant bills across a half-dozen apps, Monograph replaces the entire coordination nightmare with one integrated platform. Built specifically for A&E workflows, it connects timesheet management with invoicing in one effortless workflow, turns budget tracking into real-time profitability insights, and handles everything from consultant coordination to payment processing.
Time entries in Monograph automatically become invoice line items. Phase percentages, consultant costs, and reimbursable expenses flow straight into branded invoices without manual entry.Several firms reported adding 21% more revenue on average in their first year by eliminating billing delays and capturing work that previously fell through spreadsheet cracks.
The platform's key advantages for A&E firms make daily operations more efficient:
- Phase-based project structure that mirrors actual architectural workflows from schematic design through construction administration
- Multi-rate billing that handles staff wearing different hats across project phases
- Integrated Stripe payment processing that reduces payment cycles
- Real-time project profitability alerts when budgets hit critical thresholds
Day to day, you'll see the benefit in Monograph's MoneyGantt™ views that overlay budget versus cash received, giving you structural clarity on project health before things crack. Real-time dashboards flag when a phase is burning hot so you can adjust staffing or fees before surprises reach the client.
Monograph uses per-user monthly pricing with a five-seat minimum. It's not the cheapest invoicing option, but the payoff is a single, integrated workflow built for A&E realities: you get practice management that executes complete business operations while providing the clarity teams need for intelligent decision-making.
Best Stand-Alone Accounting Companion: QuickBooks Desktop
Most A&E firms assume they need to move everything to the cloud, but if compliance requirements or internet reliability make cloud solutions risky, QuickBooks Desktop still makes sense. Your database sits on your server, so you control who accesses project data, when backups happen, and how client information is encrypted. That control matters when you're dealing with confidential government projects or can't afford billing delays during internet outages.
The desktop version handles complex job-cost reporting without browser lag. Project profitability reports run instantly because everything processes locally. Need to reconcile consultant payments during a site visit? The offline access means you're not hunting for Wi-Fi to complete month-end billing.
However, desktop solutions require more hands-on management:
- You'll handle your own updates, server maintenance, and software installs
- Online payment options are limited compared to cloud versions
- Integrations with specialized project tools require more manual data exports
These trade-offs are manageable for firms prioritizing data control and offline access over automation convenience.
Intuit prices QuickBooks Desktop as an annual subscription rather than stacking monthly fees. For firms planning a gradual cloud transition, keep accounting local now, migrate project management later. This approach provides the reporting depth and data control you need without forcing immediate system changes across your entire practice.
Best Cloud-First Alternative: Xero
If your firm works across job sites, home offices, and time zones, you need accounting software you can access anywhere. Xero delivers that freedom with a clean interface, real-time data, and over 1,000 add-ons that let you build the exact tech stack your practice needs.
Xero handles global work naturally. Multi-currency support means you can bill an overseas client this afternoon and see the exchange rate impact immediately in your dashboard. The open API connects to time-tracking, payroll, and project-management apps without wrestling with CSV imports, no more copying data between systems.
For architects, Xero's project tracking and time billing work the way you think. Log hours by phase, attach reimbursable expenses, and push everything straight into an invoice with your logo and payment link. You can group invoices by project stage so clients understand exactly what they're paying for at each phase.
Because Xero is cloud-first, updates and security patches happen automatically. You pay monthly rather than a lump-sum license, which lowers upfront costs and scales as your studio grows. The main limitation: payroll features are limited to specific regions, so U.S. teams usually add a third-party payroll app through the marketplace.
For firms that need mobility, collaborative access, and seamless integrations, Xero offers a balanced, budget-friendly way to keep your billing moving and cash flowing.
Best for Integrated Project Management: Deltek Ajera
If you're juggling spreadsheets, time sheets, and project tracking across three different systems, Deltek Ajera puts everything on one canvas. Built specifically for A&E workflows, it tracks every hour and expense by project phase. When you move from schematic design to construction documents, the system automatically applies the right bill rates, completion percentages, and consultant costs to your next invoice. That phase-based logic means fewer missed billables and less explaining to clients why the numbers changed.
As both ERP and project management tool, Ajera's accounting goes deeper than basic invoicing. Real-time work-in-progress dashboards show whether a project is burning through fee before you notice. Resource planning highlights staff utilization and forecasts when you'll need outside consultants, keeping budgets and schedules aligned. Everything feeds the same general ledger, so you can pull firm-wide profitability reports without exporting anything.
The reality? Power means complexity. Users report steeper learning curves and quote-based pricing above lightweight tools. But if you manage multiple projects, phases, and consultants, Ajera's unified environment replaces the app juggling act and pays for itself through recovered time and cleaner cash flow.
Best All-in-One for Mid-Size Firms: BQE Core
When your 30-person studio is stuck juggling spreadsheets, time sheets, and emailed expense receipts, BQE Core feels like switching on the lights. The platform pulls every financial thread (hours, expenses, budgets) into a single dashboard so you always know where projects stand and what cash is coming next. Its project-level work-in-progress and accounts receivable tracking come from the same data that feeds your billing, eliminating the "copy-paste and hope" routine many of us learned the hard way.
Because the tool was built around professional-services workflows, timesheet entries flow straight into draft invoices with the correct phase codes and mark-ups already applied. Add reimbursable expenses captured through the mobile app, hit "send," and clients receive a branded, itemized invoice that supports online payment, all without leaving the Core ecosystem. Firms using this automation report faster payment cycles and fewer billing errors, a pattern highlighted in BQE's own guidance on accurate billing and timely payments.
For mid-size practices, that breadth is the point: Core replaces a half-dozen disconnected apps with one platform, cutting both software spend and data re-entry. Just be honest about the lift, the initial configuration can feel heavy for very small teams accustomed to lighter tools, a trade-off for the depth you gain once everything is mapped out.
BQE sells Core on a per-user, subscription basis, and its architecture bundle adds project accounting features tailored to design workflows. If your firm is big enough to need unified dashboards but not so large that you require an enterprise ERP, Core lands squarely in the Goldilocks zone: comprehensive without being lumbering.
Best Free Option: Wave
If you run a solo studio or a two-person shop, every dollar counts. That's where Wave earns its spot on this list. This web-based platform lets you send unlimited, branded invoices without a subscription, so you're not paying for features you'll never touch. You only pay standard payment-processing fees when a client pays online: a trade-off most small practices accept for the speed and convenience of digital payments. Since Wave runs entirely in your browser, you can check outstanding invoices from a job site or a café, avoiding the up-front hardware costs that desktop systems still demand.
Wave covers the basics well: customizable templates, automatic payment reminders, and a client dashboard that shows when an invoice has been viewed. Those touches keep cash moving without the follow-up emails that eat into design time. You also get simple income-expense reports that make tax season manageable.
Wave's limitations become apparent as your practice grows:
- No design phase tracking or consultant mark-ups
- Reporting stops at high-level profit and loss
- No built-in project management capabilities
- Limited multi-consultant coordination features
If you need phase-based billing for schematic design through construction administration, or if you're coordinating multiple consultants with different billing rates, you'll outgrow Wave quickly.
I recommend Wave primarily for solo architects and very small firms who need to bill cleanly, get paid quickly, and keep overhead at zero until the project pipeline justifies investing in practice management software.
Best for Large, Multi-Disciplinary Practices: Deltek VantagePoint
When you're coordinating architecture, interiors, planning, and engineering across multiple offices, spreadsheets and disconnected systems break down fast. Deltek VantagePoint handles that complexity by connecting project accounting, resource planning, and billing so your structural team in Denver and your interiors group in Austin work from the same financial data.
Track budgets by discipline and project phase, then turn that data into invoices without copying numbers between systems. Multi-company and multi-currency features help when you're managing an international practice or joint ventures with engineering firms. Real-time dashboards show utilization and work-in-progress before problems compound, critical when you're juggling dozens of active projects across different markets.
The complexity comes with significant trade-offs:
- Implementation takes months, not weeks
- Dedicated staff needed for cost codes, approval workflows, and user permissions
- Steep learning curve for teams accustomed to simple cloud apps
- Quote-based pricing with bundled per-user fees and optional modules
If you're managing hundreds of active projects across multiple disciplines and offices, VantagePoint's integrated approach beats trying to coordinate separate systems for each team. The question is whether you're ready for the implementation commitment that enterprise-level functionality requires.
Best for Government & Compliance-Focused Firms: Unanet
If your firm routinely tackles federal, state, or municipal work, you know the paperwork can feel heavier than the drawings. You're juggling cost codes, labor categories, indirect rate calculations, and the ever-present threat of a Defense Contract Audit Agency (DCAA) review. Unanet was built for exactly this environment.
Its project accounting engine lets you tag every hour and expense to granular cost codes, then locks those records behind an audit trail that shows who touched what, when, and why. When an auditor shows up, you hand them a clean chain of evidence without breaking a sweat.
Unanet's compliance-focused features include:
- Contract ceiling and funding limit tracking with real-time overrun alerts
- Labor category defaults preventing incorrect rate assignments
- Approval workflows mirroring your internal controls
- Comprehensive audit trails for government review requirements
The trade-off is cost and complexity compared to general business tools, but if you're living in the world of FAR clauses and DCAA audits, that investment keeps your team focused on design instead of deciphering cost pools.
Best Enterprise-Grade Financial Suite: Sage Intacct
When your firm spans multiple studios, disciplines, or countries, basic accounting software won't cut it: you need enterprise-grade financial management. Sage Intacct delivers that foundation as a cloud-based suite that provides rapid deployment, anywhere access, and scalable growth without managing servers or maintaining VPN connections.
Intacct's API-driven architecture connects project data, payroll, and design platforms through direct integrations, eliminating the manual data entry that consumes hours at large A&E practices. When your systems communicate automatically, firm-wide financials become real-time insights rather than month-end mysteries. Dashboards display income statements, cash-flow trends, and project profitability as they happen: the enterprise reporting finance leaders need to make informed decisions.
The investment considerations are substantial:
- Quote-based licensing with certified implementation partners
- Higher upfront costs than mid-market alternatives
- Steeper learning curve for user permissions and multi-entity consolidation
- Enterprise-grade complexity requiring dedicated IT resources
For firms ready to invest, Intacct provides capabilities that smaller platforms can't match: high transaction volumes, global currencies, and comprehensive audit trails that scale with ambitious growth plans.
Best Simple Billing for Small Practices: FreshBooks
If you're running a two- or three-person studio, every hour spent chasing invoices is time stolen from design work. Manual billing processes can cause significant payment delays after you send the invoice: cash you need for payroll and software licenses. FreshBooks cuts that delay by letting you create a branded invoice the moment a project phase wraps, pull in tracked hours automatically, and send it from the same screen. Since it's fully cloud-based, setup takes minutes, no servers to maintain, no VPN to configure, just log in from the construction trailer or your home office.
Time and expense tracking live inside the billing workflow, so those late-night site visits and client meeting miles don't vanish into spreadsheet limbo: one of the biggest ways small firms lose money. You can add online payment links, and FreshBooks sends automated follow-up reminders while you sleep. This alone prevents the follow-up gap that leaves invoices aging past 30 days.
The trade-off for simplicity is capacity. Lower-tier plans limit active clients and team members, and advanced reporting requires higher-priced plans: manageable for a boutique practice, restrictive once you grow. Still, with pricing that costs less than your daily coffee and zero IT maintenance, FreshBooks gives small architecture firms exactly what they need: straightforward billing that keeps cash flowing without drowning you in administrative work.

Streamline Your Invoicing Workflow Today
The best software for you isn't the one with the longest feature list: it's the one that fits how your firm actually works. A five-person studio chasing reimbursable expenses needs something completely different from a 200-person practice juggling multi-disciplinary teams and government audits. Start by mapping your firm size, project complexity, and the systems you already use. If your team lives in QuickBooks, choose a tool that syncs natively. If you're spread across offices or time zones, pick a cloud platform that anyone can open from a jobsite trailer.
We've seen firms double their billing speed simply by adding a practice-management system like Monograph's on top of their accounting setup. When time entries, phase percentages, and consultant costs flow straight into invoices, you eliminate the spreadsheet work that drags payments past the typical 34-day industry average.
Automated reminders and online payment links shorten that cycle further, and comprehensive financial systems can lead to significant efficiency gains and profitability improvements within the first year of implementation.
The best invoicing software is the one that fits your firm's actual workflow and grows with your practice. Get started with Monograph.
Frequently Asked Questions
What's the difference between invoicing software and practice management software?
Invoicing software handles billing and payment collection, while practice management software integrates billing with project tracking, time management, and financial reporting. Architecture firms benefit most from integrated platforms that connect project data directly to invoices, eliminating manual data entry and ensuring nothing falls through the cracks.
How much should I expect to pay for invoicing software?
Pricing ranges from free (Wave) to $45+ per user/month for comprehensive platforms like Monograph. Most architecture firms find the sweet spot around $25-40 per user/month for solutions that integrate invoicing with project management and accounting systems.
Can invoicing software integrate with QuickBooks?
Yes, most professional invoicing platforms sync with QuickBooks Online and Desktop. Monograph, Xero, and BQE Core all offer native QuickBooks integration, automatically posting invoice data to your general ledger without duplicate data entry.
Do I need separate time tracking software?
Not with an integrated platform. Tools like Monograph include time tracking that flows directly into invoicing, while standalone billing software may require separate time tracking apps. For architecture firms managing phase-based projects, integrated time tracking eliminates gaps and ensures accurate billing.
