Best CRM for Engineering Firms in 2026: Phase Billing Fit

What a CRM for engineering firms is (and what it is not)

A CRM for engineering firms is the business layer around each commission: who the client is, the fee proposal they approved, which disciplines are in scope, hours against budget and what is unpaid. It is not engineering design software, and none of the tools here replace your calculation, drafting or review tools. Technical sign-off stays where it is.

The harder question is billing. Civil, structural and MEP firms often invoice by phase, by hours or by percent complete, and track profitability per project. Tools built for AEC firms handle that with project accounting. General client-work tools handle proposals and invoices but not the accounting depth. This guide is for firms of roughly 2 to 25 people. Landscape architects have a similar workflow; see the landscape architects guide.

How we compared these tools

We compared each tool on the same five points, using only the vendor's own pages:

1. Entry price, as listed on October 21, 2026, with the billing view stated. Where a page lists no price, it says See site.
2. Phase and project billing: phased billing, billing schedules or project accounting named on the page.
3. Proposals and pipeline: fee proposals, CRM or pipeline features named on the page.
4. Time and profitability: time tracking, budgets and profitability reporting.
5. Trial terms: length and card requirement, only where the page states them.

We did not test accounting accuracy, import of existing project data, support quality or security controls, and we used no third-party ratings. Order reflects fit for a small engineering firm that bills by phase or percent complete.

The best CRM for engineering firms in 2026

1. BQE Core, best for phase billing and project accounting

BQE Core is built for architecture and engineering firms. Its pricing page lists phased billing and reporting into cost and schedule by phase, flexible billing schedules, recurring invoicing, time and expense tracking, budgets and fee schedules, Gantt charts and profitability dashboards. Accounting, CRM, HR and payroll are separate modules. The page asks you to request a custom quote and shows no price, so the price is See site. It states no trial terms, and its pages mention an iOS and Android mobile app plus open API integrations, which help when project managers log time from site visits.

Limitations: no published price, so you cannot budget from this guide, and extra modules are quoted separately. Expect a sales process rather than a self-serve signup.

Best for: firms that bill by phase and want project management, billing and accounting in one AEC-specific system.

2. Deltek Ajera, best for small firms that want project-based accounting

Deltek Ajera combines project management and project-based accounting for small architecture and engineering firms. Its page lists billing and invoicing from project data with approval routing, a schedule manager for resource planning, project dashboards and forecasting, and an Ajera Payments add-on with a client portal for online invoice payment. Deltek Vantagepoint, the larger sibling, adds a CRM and pipeline module. Neither page lists a price or a trial; both ask for a demo, so the price is See site. Ajera also lists AI help for invoice approval and timesheet entry, which matters mainly when month-end close is the bottleneck.

Limitations: no published price, and a full accounting system is more than a firm that only needs proposals and invoices may want to learn.

Best for: small firms that want accounting and project management in one A&E-focused application.

3. Monograph, best for pipeline and profitability in one A&E tool

Monograph is a platform for architecture and engineering firms with a proposal builder, project planning, staffing, time tracking, invoicing and profit reporting, plus a QuickBooks link. The pricing page lists no named plans; its calculator shows $60 to $75 per seat a month, billed annually, with a 5-seat minimum ($600 to $750 a month at 10 employees). Pipeline management is an add-on, not part of the base plan. There is no self-serve trial: subscribing starts with a demo that the vendor offers to select firms.

Limitations: the page shows only an unlabeled range, not a plan price, and pipeline costs extra.

Best for: firms that want profitability and staffing views and are happy to start with a demo.

4. Productive, best for budgets, hours and resource planning

Productive has Essential, Professional and custom-priced Ultimate plans. Its per-user figures differ between sections of the page on October 21, 2026, so the price is See site. Essential includes budgeting, resource planning, project and task management, time tracking, expense management and reporting. Professional adds invoicing integrations, recurring budgets, rate cards and billable time and expense approvals. Ultimate adds overhead calculation, multiple subsidiaries, revenue forecasting and webhooks. The page states a free 14-day trial with no credit card required.

Limitations: it is a project and resource tool, not an engineering-specific one, and its pricing page names no e-signature, no client portal and no percent-complete billing. Overhead and multiple subsidiaries sit on the custom Ultimate plan.

Best for: firms that care most about budgets, utilization and planning hours across a team.

5. Workspace369, best for fee proposals, hours and invoices on one record

Workspace369 puts the client record, Proposals that clients approve online with a deposit, a client portal, files, tasks, time tracking and invoices in one place. Cadet is $29 a month ($23.25 billed yearly) for one seat and 5 active projects; Voyager is $74 with two seats; Specialist is $149 with ten seats and adds project profitability. Time tracking, timesheets and billable time are on every plan. The screenshot below is a demo record, not a customer result.

Limitations: it has no percent-complete billing by phase, no AIA-style invoices and no multi-entity accounting, so it does not replace BQE Core or Deltek Ajera for a firm that bills that way. Productive covers budgeting and resource planning, and Harvest hours. Online booking, expenses and payment plans start at Specialist. The 14-day trial needs a card.

Best for: a firm of 2 to 10 that sells by fee proposal, bills by hours or agreed payment schedules and wants client records and invoices together, with accounting kept elsewhere.

6. Harvest, best for simple hours and invoicing

Harvest lists a Free plan with 1 seat and 2 projects, Teams at $9 per seat per month billed annually ($11 billed monthly), and Enterprise at $14 billed annually ($17.50 monthly). Teams adds unlimited seats, team reporting and accounting integrations; Enterprise adds profitability reporting and timesheet approvals. The trial is 30 days with no credit card. The page says extra invoices, projects, clients and tasks are billed by usage. Its Free plan is limited to one seat and two projects, so a firm with several concurrent commissions would move to a paid plan quickly.

Limitations: it tracks time and invoices but has no fee proposals, client portal or phase billing on its pricing page, and usage charges can raise the bill.

Best for: a small firm whose main need is clean hourly time capture and invoices. If you are weighing it against Workspace369, see the Workspace369 vs Harvest comparison.

Side-by-side comparison

Which tool fits your firm?

Run a discipline-change test during the trial

Use one fictional project with demo data in each tool you shortlist:

1. Record a civil commission with an approved fee and a deposit.
2. Add a structural discipline after approval and write the change down.
3. Send a separate fee proposal for the added scope and have the client approve it.
4. Create five tasks for the new discipline and log hours against them.
5. Invoice the added scope and trace the invoice back to its proposal.
6. Export the project records and check what comes out.

The best tool keeps the proposal, hours and invoice on one project record. If you must retype an amount between screens, that is the leak this test finds.

Set up the handoff in Workspace369

Use the engineering firms product overview to find the agreement, the responsible person, related work and the invoice. Client custom fields capture the brief, and file versioning is included on every plan. Track hours with time tracking and keep follow-up in communications.

Workflow Automations create tasks, send email or SMS, issue reminders and notify the right people, with a simulated test run and execution log before you switch a workflow on. Webhooks and the API start at Specialist. Compare plans on the pricing page; SMS and calls start at Voyager, and Cadet through Commander start with a 14-day free trial that needs a card.

When to keep it simple

If you run a handful of commissions a year, a proposal template, a time sheet and an invoice template can carry you. Move to a client-work tool when you re-key the same fee into three places, or when you cannot say which proposal an invoice belongs to. Move to an AEC accounting tool when phase and percent-complete billing starts to take real time each month.

Before moving real projects, run one full cycle on demo data and check that your records can be exported.
