SaaS vs Custom Software for Architecture Firms

Three jobs, not one

When a principal says "we need better software", they usually mean one of three different jobs, and lumping them together is how studios end up either overspending or under-tooled.

The first job is running the practice: fees split by phase, timesheets, staffing, invoices and the numbers that tell you whether a project is making money. The second is design collaboration: shared models, drawing sets, markups and coordination with consultants. The third is the client experience: how a client sees progress, approves a design option, picks finishes, signs off a stage and finds the right document six months later.

Mature products exist for the first two jobs, built by companies with far more engineers than any studio will ever hire. The third job is where generic tools fit worst, because every studio's client process is a little different and it is part of what clients are paying for.

What off-the-shelf tools cost

These are published prices, checked on 13 October 2026. Several A&E vendors only quote on request, which makes comparison harder than it should be.

When SaaS is enough

For a 12-person studio, Factor at $30 a seat comes to $360 a month. Add BIM Collaborate Pro for four Revit users and that is another $3,700 a year. Those are real numbers, but they are small next to one senior salary, and the products come with support, updates and security work you would otherwise pay for yourself.

Stay with off-the-shelf tools if your projects follow a similar shape, your clients are comfortable with email updates and PDF issue sheets, and the main complaint is that people don't fill in their timesheets. That last one matters. If the problem is habit, custom software will not fix it. It will just give people a new place not to log their hours.

A generic tool like Asana or ClickUp can also be enough for task tracking, but neither understands fees by phase. If you are tracking design fees against stages, an architecture-specific tool usually saves more admin time than it costs.

When a custom portal or tool pays off

The signals are usually practical and easy to spot. The same project information is retyped into three places every week. Clients ask "where are we?" often enough that someone spends hours writing status emails. Design options and finish selections go back and forth as PDF attachments, and nobody is sure which version was approved. A developer client or a repeat commercial client wants a branded place to see all their projects. Or you sell a repeatable service, such as interior fit-outs, with a defined set of options that a guided online flow could handle.

In those cases a small custom tool can carry real weight: a client portal with logins, a clear record of every approval with who approved it and when, selections tied to the drawing revision they belong to, and a project timeline your team updates in one place instead of in emails. None of that requires replacing the tools you already pay for.

Picture a 20-person interiors practice running eight fit-outs at once. Each client gets a finishes schedule as a spreadsheet, comments come back by email, and a junior designer spends Friday afternoons merging them into the next revision. The practice tool tracks the fees perfectly well. It just doesn't see any of this. That gap, not the fee tracking, is the thing worth building for.

To be clear about our own position: Clydara builds custom portals, dashboards and CRM-style business tools, but we don't have a published architecture-firm case study. The examples in this post are typical studio situations, not client stories.

Build thin, on top of what you already pay for

The mistake to avoid is rebuilding practice management or document control from scratch. Keep your practice tool as the record for fees and time, and your BIM platform as the record for models. Build only the layer that is missing, and connect it through whatever exports or APIs your tools provide. Check that before anyone writes a line of code, because it decides how much of the portal can update itself.

Running costs for a small portal like this are modest. A React front end with a managed Postgres database, authentication and transactional email sits in the first-customers column of our SaaS infrastructure cost breakdown, around $110 to $140 a month on list prices. The build is the larger cost, and our custom SaaS development process explains how to keep the first version small. Whatever you build, keep the code, hosting and domain in the studio's name.

A quick test before you spend anything

For two weeks, have the team note every time they copy information from one system to another or write a status update by hand. Multiply the hours by an internal cost rate and you have a rough monthly figure for the problem. If that number is smaller than the running cost plus a sensible share of the build cost, stay with your current tools and tidy up the process instead.

Then try the cheapest workaround for a month: a shared approvals folder with a naming rule, or a form that logs sign-offs. If the workaround holds, you have saved real money. If it collapses under real projects, you now know exactly what the custom tool needs to do, which is the best brief a developer can get. Our broader custom software vs SaaS guide has a worksheet for the full cost comparison.

Frequently asked questions

Where we land

Buy the tools that run the practice and the tools that handle the models. Consider custom software only for the part of your process clients actually see, or for the copying and chasing your bought tools leave behind, and only after a cheap workaround has failed.
