Interior design software: tools that run projects, purchasing and billing

What should interior design software do?

The best tools join the creative side and the business side. Look for these features.

• Product clipper: You save a product from any vendor website with one click, including the image, price and size.
• Specs and schedules: Each room has a list of items with finishes, quantities and lead times.
• Client approvals: Clients see selections in a portal and approve or reject each one online.
• Proposals and purchase orders: One approved item turns into a client proposal and a vendor order without retyping.
• Markup tracking: The system knows your cost, your markup and the price the client pays.
• Deliveries: You track orders, shipments and receiving so nothing sits lost at a warehouse.
• Time billing: Designers log hours against each project, and the hours flow into invoices.
• Payments: Clients pay deposits and invoices by card or bank transfer.

Which interior design software do firms use, and what does it cost?

These prices come from each vendor's own pricing page in October 2026. Vendors often change plans, so check the page again before you sign up.

Houzz Pro

Houzz Pro lists three plans on monthly prices. Design costs $99 a month for one user. It includes 3D floor plans, selections, the product clipper, mood boards, a CRM, proposals, invoices and online payments. Pro costs $199 a month and adds budgets, contracts, change orders, schedules and daily logs. Teams starts at $399 a month with unlimited users and adds AI note-taking, email marketing and a custom website. Houzz offers a 30-day free trial and labels all three plans as enhanced with Houzz AI.

Studio Designer

Studio Designer joins project management, product sourcing and full accounting in one system. It prices per user. Essentials costs $69 per user a month billed yearly, or $79 billed monthly. Professional costs $79 billed yearly, or $89 monthly. Premier costs $109 billed yearly, or $119 monthly. Every plan includes general ledger accounting, purchase orders and its StudioPay payments. Professional and Premier add advanced proposals, a custom document editor and fuller time billing. Studio Designer says its payroll runs through Gusto.

Programa

Programa sells one Pro plan with every feature and unlimited projects. Its pricing page shows $71 a month for one seat, plus $31 a month for each extra seat. The page does not name the currency, so check what you will pay at checkout. Features include a web clipper, schedules, procurement, quoting, invoices, time tracking and a client dashboard. There is a 7-day free trial with no card needed.

Gather

Gather focuses on specifications and purchasing. Core costs $228 a month billed yearly and includes 5 seats, with extra seats at $31 a month. It covers the clipper, specs, schedules and client approvals. Core Plus costs $276 a month billed yearly and adds budgets, budget vs actuals, purchase orders and delivery tracking.

What should a design firm check before buying?

A good demo shows a pretty board. Your real test is what happens after the client says yes. Run one past project through each trial.

• Your markup rules: Enter a real item with your cost, markup, freight and sales tax. Check the client price comes out right.
• Vendor orders: Turn approved items into purchase orders. See if the tool groups items by vendor for you.
• Accounting fit: Decide if you want accounting inside the tool, as Studio Designer offers, or in your current books.
• Client view: Open the client portal as a client would. It should be clear and easy on a phone.
• Team cost: Work out the yearly price at your real head count. Per-user and per-seat plans add up in different ways.
• Getting data out: Ask how you export specs, orders and client history if you switch later.

If a client portal is the main gap, my guide to client portals covers your options.

Which AI features help interior designers?

AI helps designers most with the slow admin around each item. These uses save real hours.

Product details from a photo or link

A designer pastes a link or a photo of a chair. AI pulls the name, size, finish, price and lead time into the spec sheet. The designer checks the details and saves. This cuts the typing that eats a junior designer's week.

Meeting notes into tasks

After a client meeting, AI turns the recording into a short summary and a task list. "Client wants a darker oak" becomes a task on the right room. Houzz Pro Teams already includes AI note-taking.

Order and delivery chasing

AI reads vendor emails about ship dates and backorders. It updates the order status and flags any item that will miss the install date. The designer then calls the client before the problem becomes a surprise.

When does custom interior design software make sense?

Most studios should buy. The tools above are made for designers, and a small firm can be running on one in a week. Start with a trial of two products and pick the one your team uses without help.

A design firm should consider custom software in these cases.

• Unusual pricing: You mix flat fees, hourly billing, cost plus and retail pricing, and no tool handles your mix.
• Trade or showroom work: You also sell to the trade, run a showroom or make your own furniture, so you need inventory and wholesale pricing.
• Too many tools: Your specs, orders, accounting and client updates sit in four systems, and staff copy data between them.
• Your own client experience: You want a branded portal or quote tool that matches how you present work.
• Seat costs: A growing team on per-user plans pays more each year for the same software.

A mixed approach often works well. Keep a product for specs and add a custom piece, such as an AI order tracker or a link to your accounting system. My guide on whether to build or buy software walks through that choice.

How would Blur Studio approach a design firm's software?

I start with two finished projects. I trace every product from the first idea to the final install and the last invoice. I look for retyped data, lost markups and orders that slipped. If a product fixes those gaps, I name the one to trial and stop there. If the gap is real, I build the missing part myself. That could be an AI agent that tracks vendor emails, a client portal or a full system for a firm that also sells furniture. Your studio keeps the code and every account in its own name, and I keep the tool working after launch.
