Odoo vs Monograph for architecture firms: cost and fit

In the Odoo vs Monograph choice, keep Monograph if your practice bills by design phase, needs phase-fee planning and visual project health, and is content to keep accounting in QuickBooks Online. Move to Odoo if you also need consultant purchasing, resource planning across projects, proposals in a CRM and one ledger for several offices. Both tools track phase fees, but they divide the work differently: Monograph sits beside your ledger, while Odoo keeps projects, time, purchasing and accounting in one database. This guide compares them on phase billing, cost and fit for a studio of 20 to 100 people, with a worked example you can rebuild with your own numbers.

Flectic implements Odoo for architecture and planning practices that bill by design phase, with a package proposed at 10 to 12 weeks for Core. It also implements Microsoft Dynamics 365 and earns no vendor quota on either platform, so staying on Monograph is a recommendation it will make when your phases fit.

The choice depends less on features than on where your records live. A studio that bills phases in Monograph and posts invoices to QuickBooks runs two systems with a sync between them. A studio on Odoo runs one database, where the consultant bill, the timesheet and the client invoice sit on the same project record.

What Monograph covers for a phase-billing practice

Monograph is a firm-management platform for architecture and engineering firms. Its pricing page says the plan includes "unlimited access to every core Monograph feature", along with onboarding support, on-demand training, a learning center, unlimited projects, unlimited reports and project accounting (Monograph pricing, October 2026). Pipeline is not in that plan. The same page says it is offered separately as an add-on.

For phase work, Monograph's own material describes phase budgets that are "easy to monitor and forecast", billing that follows phase completion, and integrated platforms that track consultant costs and generate client invoices with pass-through charges (Monograph, AI billing for A&E firms, accessed October 2026). That covers the core of a phase practice: budget by phase, bill against progress, and carry consultant costs to the client invoice.

The accounting stays outside Monograph. Monograph's QuickBooks Online article says invoices, consultant bills, expenses, clients and consultants can be kept in sync with QuickBooks, and it describes QuickBooks as the place for "general ledger, tax preparation, and standard invoicing" (Monograph, QuickBooks Online integration, accessed October 2026). The article does not describe timesheet entries moving into QuickBooks, so check that step with the vendor before you rely on it. In practice, your principals see phase health in Monograph, and your finance team closes the books in QuickBooks.

What Monograph costs

Monograph's pricing page shows a range of USD 45 to USD 490 a month. It does not name plans, state a per-user price or give a seat minimum (Monograph pricing, October 2026). A third-party review updated in July 2026 reports Track at USD 25 per member a month on annual billing and USD 30 monthly, and Grow at USD 45 per member a month on annual billing and USD 55 monthly (Cloudwards, Monograph review, July 2026). Treat the review as a reviewer's figure and get a written quote for your seat count.

What Odoo covers for the same practice

Odoo prices licenses per user, and the plan you choose changes what you get. Odoo Standard includes all apps on Odoo Online. Odoo Custom adds multi-company support, Odoo Studio and external API access (Odoo pricing, October 2026). Odoo's prices vary by currency, billing period and country, so read the figure for your country on that page before you budget.

Odoo's project profitability view is the part that matters for phase work. The Odoo 19.0 documentation says the profitability dashboard shows records linked to the project and its analytic account, split into revenues and costs. Its Expected column holds "the amounts expected based on existing sales or purchase orders", and the Costs list includes the total cost of purchase orders linked to the project (Odoo 19.0 documentation, project profitability, October 2026). A record only appears there when it is linked to the project and its analytic account, so a consultant purchase order has to be raised against the project. Once it is, a principal can see the fee next to the consultant cost already committed, in the same view.

The Odoo Architecture and Planning package from Flectic adds the architecture-specific layer. Core records each design phase with its fee, hours and consultants, and configures four reports, including fee used by phase and unbilled time. Consultant appointments are raised in Purchase against the project's analytic account. Growth adds studio staff records, a client request desk and principal dashboards (Flectic, Odoo Architecture and Planning package). Flectic's proposed timelines are 10 to 12 weeks for Core and 12 to 16 weeks for Growth. Those timelines depend on scope, data readiness and timely client decisions. The page prices licenses, hosting, taxes and paid connectors separately, so the Odoo license line sits on top of the implementation fee.

A worked example: phase fee, consultant cost and forecast margin

The example below shows the arithmetic a principal should see on one phase. It assumes:

• A schematic design phase with a fixed fee of USD 60,000.
• A budget of 300 hours at a blended cost of USD 120 an hour, plus a consultant allowance of USD 12,000 for structural and MEP work. Budgeted cost is USD 48,000, so budgeted margin is USD 12,000, or 20% of the fee.
• At 75% complete, the team has logged 255 hours and consultants have invoiced USD 9,000.
• Scope is unchanged, and the consultant spend that remains stays at the allowance.
• Fee earned to date (Calculation: 75% of USD 60,000 · Result: USD 45,000)
• Cost to date (Calculation: 255 hours at USD 120, plus USD 9,000 consultants · Result: USD 39,600)
• Hours used (Calculation: 255 of 300 budgeted hours · Result: 85% of hours with 75% of the phase done)
• Forecast hours at completion (Calculation: 255 divided by 0.75 · Result: 340 hours)
• Forecast cost at completion (Calculation: 340 hours at USD 120, plus USD 12,000 consultants · Result: USD 52,800)
• Forecast margin (Calculation: USD 60,000 less USD 52,800 · Result: USD 7,200, or 12% of the fee)

The phase still clears, but the forecast margin falls from 20% to 12%. The 40 hours over budget cost USD 4,800, which is the gap between the planned USD 12,000 margin and the forecast USD 7,200. At 75% complete, USD 15,000 of fee is left, and USD 13,200 of cost is still to come, so the last quarter of the phase has a thin margin unless someone changes the plan.

A principal who sees this at 75% can reduce scope, move hours to a cheaper role or raise an additional-service request for the extra work, and that request can be billed as its own fee line. If the same drift shows up only on the month-end invoice, the phase is already closed and the margin is already lost.

What the license gap is worth

Assume a 25-user studio in the US. Monograph Grow at USD 45 per member a month on annual billing comes to USD 1,125 a month, or USD 13,500 a year. Odoo Standard lists at USD 24.90 per user a month on yearly billing in year one, then USD 31.10, as shown in Flectic's Odoo pricing calculator. For 25 users that is USD 7,470 in year one and USD 9,330 a year after that. Prices differ outside the US, so use the figure for your country.

The license gap is USD 6,030 in year one and USD 4,170 a year after that, or USD 14,370 over three years. That gap is before implementation. It is also before QuickBooks, which Odoo could replace as the ledger, and before any Monograph add-on such as pipeline. If you keep QuickBooks and still pay for Monograph, the gap is not a saving. It is the cost of running two systems. For Odoo to pay back, its implementation cost and internal time have to be recovered from that gap and from any QuickBooks subscription you retire.

Fair comparison on the needs that decide the choice

• Phase budgets and billing (Monograph: Phase budgets that are easy to monitor and forecast, with billing that follows phase completion (vendor material) · Odoo: Phase records with fee fields and fee used by phase in the Flectic Core scope)
• Consultant costs (Monograph: Consultant costs tracked and carried to client invoices as pass-through charges (vendor material) · Odoo: Consultant purchase orders tagged to the project's analytic account, costs visible in the profitability view (Odoo documentation))
• Timesheets (Monograph: Time tracking and draft invoices from approved timesheets (vendor article) · Odoo: Timesheets against the project, with revenue and cost on the same dashboard)
• General ledger (Monograph: Stays in QuickBooks Online, with invoices, bills, expenses, clients and consultants synced · Odoo: Odoo holds the ledger, so there is no second system to sync)
• Proposals and pipeline (Monograph: Pipeline is a paid add-on (Monograph pricing) · Odoo: Proposals and projects live in one database)
• Setup (Monograph: Hosted product with onboarding support and training in the plan (Monograph pricing) · Odoo: A phased project. Flectic proposes 10 to 12 weeks for Core and 12 to 16 weeks for Growth)
• Licenses (Monograph: USD 25 to USD 55 per member a month in a third-party review, range USD 45 to USD 490 a month on the vendor page · Odoo: Per user, varies by currency and country, with Standard and Custom plans (Odoo pricing))

Monograph wins on time to first use. Its plan includes onboarding support and training, so a small team can start without an implementation project. Odoo wins when the work crosses systems: consultant purchasing, cross-project resource planning, proposals and one ledger for several offices. Neither tool removes the need to set phase rules, fee structures and approval steps before you go live.

Where Monograph fits better

Monograph is the better choice in four situations:

• A small studio that mostly needs phase-based fee planning and visual project health.
• A practice that keeps QuickBooks Online as its ledger and has no need to report across offices in one database.
• A firm that wants a hosted tool with onboarding support and training, without an implementation project.
• A practice with little consultant purchasing to manage, where consultant costs are passed through to the client and nothing more.

If your practice is in one of these groups, keep Monograph and fix the process before you buy anything else.

When Odoo fits better

Odoo earns its cost when the work spans more than the phase record. Look at these five signs:

1. You buy consultant and subconsultant services through purchase orders, and you need to see committed cost against each phase before the invoice arrives.
2. You plan people across projects, so one designer's hours on three phases in a month are visible in one view.
3. You quote in a CRM and want the proposal and the project to live in the same database.
4. You report across several offices and need one ledger behind the numbers.
5. You are already moving off QuickBooks, or you expect to within two years.

If two or more of these describe your practice, price both options against your own seat count before you decide. Flectic implements the Odoo Architecture and Planning package for practices in this position, and the first 30-minute call is free. Our professional services ERP page covers the wider flow from proposal to cash for other firms. For the broader professional services picture, see Odoo for professional services firms and ERP options for professional services firms.

Where Flectic fits

Monograph is a hosted tool you start using with its own onboarding. Flectic is the consultancy that implements Odoo for an architecture or planning practice of 20 to 100 people that bills by design phase and wants consultant purchasing, studio scheduling and the ledger beside the phase fees. Flectic implements both Odoo and Microsoft Dynamics 365, earns no vendor quota on either and holds no certification from either vendor.

Choose Flectic if

• You buy consultant services through purchase orders and want committed cost against each phase before the invoice arrives.
• Proposals, projects and the ledger should live in one database, possibly across offices.
• You are moving off QuickBooks, or expect to within two years.

Look elsewhere if

• A small studio mainly needs phase-fee planning and keeps QuickBooks as the ledger. Monograph is faster.
• You want a hosted tool with training and no implementation project.
• You need a vendor-certified partner.

The scope is on the Odoo Architecture and Planning package page.

How to decide without rebuilding your phase history

Work through these steps before you request a demo or a proposal:

1. List every place a phase fee, a timesheet, a consultant invoice and a client invoice is recorded today. Count the manual handoffs between them each month.
2. Ask your project leads which phase overran last year and when anyone noticed. The answer tells you whether the problem is visibility or process.
3. Price both options for your actual seat count. Use the vendor pages for the list price, and get written quotes for the seats you need.
4. Ask each vendor what the first phase includes, which data it migrates and who signs off on the phase rules. Ask for the same answers in writing.
5. Decide on the ledger first. If QuickBooks stays, a specialist tool with a clean sync may be enough. If it goes, plan the cut-over date before you choose the implementation partner.

Keep the open-project history on the day of cut-over. A phase that started in one tool and closes in another needs its fee, hours and consultant commitments carried across, or the margin figures will restart at zero.
