Engineering consultancies run on a mix of work that doesn’t fit neatly into one timesheet line: billable hours for a client, internal review time, site visits, drawing revisions, and the odd fire drill when a deadline moves up. Tracking all of that by memory or in a spreadsheet works for a while, until a client asks why an invoice looks different from what was quoted, or a project that felt busy turns out to have barely broken even.
The fix is the same one most professional services firms land on: dedicated software that tracks time, ties it to project cost and billing, and gives you a clear picture of where a project actually stands. That fix falls under the broader umbrella of engineering project management software, but a consultancy’s version of the problem is more specific: client billing, project profitability per engagement, and juggling several clients’ work at once, on top of whatever technical workflow the engineering side already runs. Below, we cover the tools built for exactly that: time tracking and billing software for client-facing consulting work, and the project management and PSA platforms engineering consultancies use to run it.
Why engineering consultancies need dedicated tools
Engineering consulting has a specific shape that generic business software doesn’t always account for: work is billed to clients, often across several concurrent projects, and the technical side of the job (drawings, calculations, site visits, revisions) doesn’t always map cleanly onto a simple task list. A few problems show up often enough to be worth naming directly:
- Billable time goes untracked. A quick call with a client or a site visit that runs long rarely gets logged if logging time means opening a spreadsheet after the fact. That’s revenue that quietly disappears.
- Project profitability is a guess until the project ends. Without time and cost data in one place, you find out a project ran over budget when it’s already over, not while there’s still time to adjust scope or staffing.
- Client billing takes longer than the work itself. Reconstructing hours from memory or scattered notes just to handle client billing and invoicing is its own project, and it’s one that doesn’t bill any hours back.
- Revisions and change orders get lost in email. Engineering work involves more back and forth than a fixed deliverable; without a system tracking scope changes, it’s easy to do unbilled work that was never part of the original agreement.
Dedicated time tracking, billing, and project management tools close these gaps, which is why most engineering consultancies end up running at least one of them alongside whatever technical software their discipline requires.
Time tracking and billing tools
These tools focus on the core of consulting work: capturing billable hours accurately and turning them into invoices without a manual reconciliation step at the end of the month. If you want the day-to-day process rather than a tool comparison, our guide to consultant time tracking covers that on its own.
1. actiTIME
Key features:
- Online timesheet
- Task management
- Billing & invoicing
- Cost of work reports
- Mobile apps
Why it works: actiTIME tracks billable and non-billable time by client and project, then turns tracked hours and billing rates directly into a PDF invoice, so there’s no separate step to reconcile before the invoice goes out. Cost of work reports show what each engagement actually cost in staff time, next to what it billed, which is what turns “felt busy” into an actual profitability number.
Best for: Engineering consultancies of any size that want time, cost, and billing data in one place instead of stitching a timesheet, a spreadsheet, and an invoicing tool together.
Pricing: Free for up to 3 users; $6/user/month for 1–40 users, $5/user/month for 41–200 users (billed annually); self-hosted from $120/user as a one-time purchase.
Free trial: 30 days, no credit card required.
Rating: Capterra 4.6 (111 reviews).
Pros:
- Free version has no expiration date for small consultancies, unlike a typical time-limited trial
- Invoices generate directly from tracked billable time, no re-entering hours into separate billing software
- Available as both cloud and self-hosted, useful if client data can’t leave your own infrastructure
Cons:
- Invoicing covers generating a PDF from tracked hours and rates; it doesn’t handle online payment collection the way a dedicated billing suite does
Now we can better predict future project requirements
Our company needed a simple way of tracking time used on multiple projects, and actiTIME fit the need. Its interface is simple and easy to maintain. We use the application for time management, task estimation, and also to communicate deadline information to our team members. Now having actiTIME we can better predict future project requirements!
2. Journyx
Key features:
- Project cost accounting
- Multi-level approvals
- Resource capacity planning
- ERP & payroll integrations
Why it works: Journyx is built for organizations that need project accounting depth, not just a timer, with approval workflows and data validation rules that catch incomplete or miscoded entries before they reach billing. Integrations with Microsoft Dynamics, NetSuite, QuickBooks, and ADP mean tracked time can flow straight into whatever accounting system your firm already runs.
Best for: Engineering consultancies with more complex compliance or approval requirements, especially those already using an ERP or payroll system Journyx integrates with.
Pricing: Project Time Tracking from $13/user/month (list price); Time & Attendance from $5/user/month; onboarding and additional modules add to the cost.
Free trial: Not publicly listed; Journyx offers a price estimate tool and demo instead.
Pros:
- Multi-level approval workflows and validation rules suit firms with stricter billing sign-off processes
- Deep integrations with major ERP and payroll systems reduce duplicate data entry for firms already on one
Cons:
- List pricing doesn’t include onboarding or additional modules, so the real cost can run higher than the headline number
3. ClickTime
Key features:
- Timesheets & approvals
- Project budgeting
- Resource management
- 70+ reports
Why it works: ClickTime layers project budgeting and resource management on top of standard time tracking, so a project manager can see who’s overbooked and which projects are burning through budget before either becomes a client-facing problem.
Best for: Engineering consultancies that want project budget tracking and resource management alongside time tracking, without moving to a full PSA platform.
Pricing: Starter $15/user/month (up to 25 users); Team $19/user/month (up to 200 users, adds approval workflows and advanced billing rates); Premier $31/user/month (adds project budgeting and resource management); Enterprise custom. Annual billing brings each tier down (Starter $12, Team $15, Premier $27 per user/month).
Free trial: Not publicly listed on the pricing page.
Pros:
- 70+ built-in reports cover most reporting needs without custom report-building
- Annual billing discounts are meaningful, 13–20% off depending on tier
Cons:
- Project budgeting and resource management, arguably the most useful features for a consultancy, only unlock on the top Premier tier
Project management and PSA tools for engineering firms
Once a firm is running several engagements across multiple clients, a professional services automation (PSA) platform, one that bundles project management with project accounting and resource planning, often replaces a stack of separate tools. All three are made for architecture and engineering (A&E) or broader professional services firms, rather than adapted from generic project management software. If your team’s main gap is closer to project management for engineers in general than the consulting and billing side, that guide covers the process itself in more depth.
1. Deltek Ajera
Key features:
- Project-based accounting
- Schedule Manager
- Automated invoicing
- Role-based dashboards
Why it works: Ajera merges project management and project-based accounting into a single application built specifically for small A&E firms, rather than a generic PM tool with billing bolted on. Automated invoice generation and approval routing are built around how engineering firms actually bill, phase by phase and client by client.
Best for: Small architecture and engineering firms that want project management and project accounting to come from the same system instead of two that need to be kept in sync manually.
Pricing: Not published; Deltek directs prospects to request a demo for pricing.
Free trial: Not publicly listed; demo-based.
Pros:
- Built specifically for A&E firms rather than adapted from a general-purpose PM tool
- Approval routing and invoice templates already match how engineering firms bill phase by phase, so there’s no setup work reshaping a generic workflow
Cons:
- No published pricing means you can’t gauge cost fit without going through a sales conversation first
2. BQE Core
Key features:
- Time & expense tracking
- Project profitability
- Resource planning
- Billing & ePayments
Why it works: BQE Core is an all-in-one platform for architecture, engineering, and consulting firms, with a modular structure: start with the Foundations module (time, expense, billing, project management, reporting) and add accounting, CRM, HR, or payroll only if you need them.
Best for: Engineering consultancies that want project management, billing, and financial reporting in one system, and would rather add modules as they grow than pay for a full suite upfront.
Pricing: Per-user, modular pricing; a custom quote is required based on firm size and which modules you need.
Free trial: Not publicly listed; BQE offers a custom quote and demo instead.
Pros:
- Modular pricing means you’re not paying for accounting, CRM, HR, and payroll modules you don’t need yet
- Reports over 3,000 A&E firms as customers, a real base of firms with the same billing and project structure as yours
Cons:
- No published pricing or free trial, so evaluating cost fit means going through a sales conversation
3. Accelo
Key features:
- Project & resource management
- Time & billing
- Client work tracking
- Retainer management
Why it works: Accelo is a PSA platform that explicitly targets engineering and architecture firms alongside consulting, accounting, and agency businesses, covering the full client work lifecycle from quote to project to invoice in one place. That end-to-end scope is what Accelo points to when it claims typical customers recover 3–7% of revenue that otherwise leaks out through untracked scope creep and unbilled work.
Best for: Engineering consultancies juggling multiple client engagements that want quoting, project delivery, and billing connected end to end rather than tracked in separate tools.
Pricing: Custom, based on team size and growth goals; request a quote directly from Accelo.
Free trial: Not publicly listed; onboarding and setup support are included with a paid plan.
Pros:
- Covers the full client lifecycle, quoting through billing, rather than just the project execution middle
- Built-in onboarding support helps offset the setup work a full PSA platform usually requires
Cons:
- No self-serve pricing or trial, so you can’t test-drive it before a sales conversation
How to choose the right tool for your firm
- Start with what’s actually broken. If untracked billable hours are the pain point, a full PSA platform is more than you need right now; if you’re already tracking time well but invoicing and project accounting are the bottleneck, that’s where the extra complexity of a PSA tool starts paying off.
- Match the tool to your firm’s size and structure. A solo consultant or a two-person practice rarely needs the resource planning and approval chains built into an enterprise PSA platform; straightforward small business time tracking usually covers it instead. A 30-person multi-discipline firm usually outgrows a standalone time tracker fairly quickly.
- Check what it costs to bill the way you already bill. Engineering work often mixes hourly, fixed-fee, and phase-based billing on the same project. Confirm the tool can represent your actual billing structure, not just a simplified version of it.
- Weigh published pricing against demo-only pricing. Tools with clear, public pricing (like actiTIME, Journyx, or ClickTime) let you compare costs before you invest time in a sales process. Demo-only tools (like Deltek Ajera, BQE Core, or Accelo) usually mean deeper features, but also a longer evaluation cycle.
- Use the free trial or demo on a real project. A tool that looks clean with sample data can behave very differently once your actual clients, tasks, and billing rates are in it.
Common mistakes to avoid
- Buying PSA-level complexity before you need it. A small consultancy paying for resource planning and multi-level approval chains built for 50-person firms is paying for overhead it doesn’t use yet. Upgrade when the problem becomes real, not before.
- Letting billing categories stay undefined. If it’s unclear upfront what counts as billable versus internal time, entries end up inconsistent, and that inconsistency shows up as disputed invoices later. A documented timesheet management process heads this off before it starts.
- Migrating every client and project at once. Moving your full client list and project history into a new system in one go is how data gets lost and the team gets confused mid-transition. Run one active project through the new tool end to end first.
- Ignoring what happens to your data if you leave. Before committing, particularly to a demo-only tool without published pricing, confirm you can export your time, project, and client data in a usable format.
How to roll out new software on your team
Choosing the right tool is only half the job. Whether your team actually uses it, and trusts the data it produces, depends on how it gets rolled out.
- Explain the benefit to the person logging time, not just to management. Accurate billing protects the hours someone actually worked, and a five-minute invoice beats an afternoon of reconstructing a timesheet from memory. That’s a better pitch than “so we can see what you’re doing.”
- Define billing categories before day one. Decide upfront how site visits, revisions, and internal review time get categorized, and write it down somewhere the whole team can check.
- Pilot on one project first. Run a real, current engagement through the new tool end to end, from time entry to invoice, before switching your whole firm over.
- Review the first billing cycle closely. The first invoice run out of a new system is where you catch missing setup steps, before they repeat across a full quarter of projects.
The right tool turns tracked time into a clearer picture of the business
Every tool on this list solves some version of the same problem: getting engineering consulting work, and what it actually costs to deliver, out of memory and spreadsheets and into a system you can trust. Some, like actiTIME, are built to start simple and scale with a growing firm. Others, like Deltek Ajera, BQE Core, and Accelo, are built specifically around the accounting and billing complexity that comes with running a multi-discipline engineering consultancy.
Whichever direction fits your firm, the real payoff isn’t the software itself, it’s knowing which projects were actually profitable instead of guessing after the fact.
FAQ
Is a standalone time tracker enough, or does a small engineering consultancy need a full PSA platform?
For a solo consultant or a small team billing a handful of clients, a standalone time tracker with basic invoicing, like actiTIME, usually covers it. A full PSA platform like Deltek Ajera, BQE Core, or Accelo earns its extra cost and complexity once a firm has several consultants, overlapping projects across disciplines, and needs project accounting, resource planning, and billing approvals to live in one system instead of a tracker plus a spreadsheet plus separate accounting software.
When does a small engineering consultancy actually outgrow spreadsheets for time tracking and billing?
Usually the moment reconstructing an invoice from memory or scattered notes starts taking real time each month, or a client questions an invoice and there’s no detailed record to back it up. A spreadsheet can hold hours for a one- or two-person practice for a while, but it doesn’t flag overbudget projects while there’s still time to act on it, and it doesn’t scale once more than one person needs to log time against the same client’s projects.
Is it worth switching from a general task tracker like Asana or Trello to a billing-focused tool?
Depends on what’s actually missing. A general task tracker is fine for organizing work itself, assigning tasks, tracking status, but most weren’t built to turn tracked hours into a client invoice or show project profitability. If billing and cost visibility are the actual gap, a dedicated time tracking or PSA tool closes it directly; if task organization is the only pain point, switching tools won’t fix a billing problem you don’t have yet.
