How Much Does Interior Design Project Management Software Cost in 2026?

Software pricing pages in this category are hard to compare: some charge per seat, some per plan, some ask you to book a demo before showing a number. This guide puts the 2026 prices side by side, by studio size, so you can see what a 1, 3 or 5-person studio actually pays.

How much does interior design project management software cost per month?

Most interior design project management platforms cost between $30 and $120 per user per month in 2026. Per-seat tools such as Studio Designer ($79-119 per user), Mydoma Studio ($64 per user) and Programa ($71 plus $31 per extra seat) grow with team size. Planify charges a flat $29.99 per month for the whole studio, or $24.99 per month billed annually.

The headline price rarely tells the whole story. What matters is the price at your team size, and whether the features you need sit in the base plan or behind an upgrade. If you are still choosing a platform, our overview of project management software for interior designers covers features in detail.

What do the main platforms cost at different studio sizes?

For a solo designer, the main platforms cost between $29.99 and $79 per month. At three people the range widens to $29.99-237 per month, and at five people to $29.99-395 per month, because most tools charge per seat while Planify charges one flat studio price.

Prices are monthly billing in USD, verified on vendor pricing pages and Capterra on 15 October 2026. Annual billing lowers most of them: Planify drops to $24.99 per month, Studio Designer Essentials to $69 per user, and Mydoma Studio to $691 per user per year. Houzz Pro shows designer plans on request.

What does Planify cost?

Planify costs $29.99 per month billed monthly, or $24.99 per month billed annually (EUR 24.99 and EUR 20.99). The price covers the whole studio, not each user, and includes the client portal, FF&E tracking, AI product import, proposals, budget tracking and scheduling. There is a 21-day free trial with no credit card.

There are no feature tiers. A solo designer and a five-person studio use the same product at the same price, so adding a junior designer or an assistant does not change your bill.

Why does per-seat pricing matter so much for small studios?

Per-seat pricing turns every hire into a software cost. A studio that grows from one to three people on a $64-per-user tool goes from $64 to $192 a month, while the work itself has not changed. Flat studio pricing keeps the software cost fixed as the team grows.

This is the main reason small studios end up running a spreadsheet next to their software: the extra seat is too expensive for the part-time assistant who only updates the product list. We looked at this in more detail in the best interior design software for small studios.

What should be included in the base price?

For interior designers, the base price should cover the full project flow: FF&E specification, client approvals, proposals, budget tracking and a client portal. If any of these sit behind an upgrade or an add-on, the real monthly cost is higher than the advertised starting price.

When you compare pricing pages, check three things: whether the client portal is included, whether clients need their own login (and seat) to approve items, and whether proposals are generated from your product list or rebuilt by hand.

How does integrated budget tracking affect the real cost?

Integrated budget tracking removes the second tool most studios pay for in time: the spreadsheet. When the budget is linked to the product list, every price change, approval or deletion updates the totals automatically, so nobody has to reconcile two files before sending a client update.

In Planify, items in the materials and labour list feed the budget tracker directly, and the same items build the client proposal. That link between specification, budget and proposal is where most of the time savings come from.

How do I calculate the return on interior design software?

Compare the monthly fee with the hours the tool removes. If AI product import, live budget tracking and proposal generation save a designer three hours a month, and that time is billed at $75 per hour, the tool returns $225 a month. At $29.99 per month, Planify pays for itself if it saves roughly 25 minutes a month.

A practical way to measure this is to time one real task before and after: building the product list for one room, or turning that list into a client proposal. Designers who previously copied product details by hand into Excel usually see the biggest difference.

Are the expensive platforms worth it for larger firms?

Enterprise platforms such as Studio Designer make sense for larger firms that need deep accounting integration and purchase-order workflows across many staff. For studios of one to ten people, the extra cost per seat usually pays for accounting depth they do not use.

How can I test a platform before committing?

Run one real project through the trial instead of a demo project. Add the products for one room, send the client portal link, collect an approval and generate a proposal. If that full loop works with a real client, the platform will work for the rest of your projects.
