Interior design software pricing in 2026: every published price, verified and dated

What Planify, Houzz Pro, Studio Designer, Design Manager, DesignFiles, Programa, Gather and NYA cost — taken from each vendor's own pricing page on 2026-08-03, with the seat maths worked out.

By Idan Mann, founder of NYA

All competitor prices on this page were taken from the vendor's own pricing page on August 3, 2026 and are linked at the bottom. Prices change — tell us if you spot one that has.

Almost every comparison of interior design software quotes prices without saying when they were checked, and several of the most-linked pages are simply wrong. Everything below came from the vendor's own pricing page on the date at the top of this article.

Entry price, side by side

The four billing models, and why they matter

Every price disagreement in this category comes down to which of four billing models a vendor chose. Once you know the model, you can predict your bill at any headcount.

• Flat per studio or firm. Planify is $24.49/mo on annual billing for unlimited team members. NYA uses flat team-size tiers at $49, $129 or $299 a month. Neither adds a fee for each person you hire, though NYA steps up when a firm crosses a plan boundary.
• Base plus per-seat. A first-seat price, then a smaller fee per additional person: DesignFiles (+$30), Programa (+$31), Gather (+$39), Houzz Pro (+$60). Cheap solo, compounding with every hire.
• Per user, every user. Everyone pays the full rate: Studio Designer at $69–$109/user and Mydoma at $58/user. The bill scales linearly with your team, whether or not each person lives in the software.
• Published base plus a quote-gated advanced tier. Houzz Pro lists Pro at $249/mo plus $60 for extra users, while Custom still requires a demo. Budget from the public Pro rate unless the advanced feature set is required.

What each product actually costs

Planify — $24.49 flat with annual billing

Two published rates, and most write-ups only quote one: $29.99/mo flat month-to-month, stated in Planify's own pricing FAQ, or $24.49/mo billed annually at $293.88. Both include unlimited active projects and unlimited studio team members, so it is the lowest verified flat price in this comparison either way. The trial is 21 days with no card. Its published scope is where the limit sits — FF&E, client approvals, proposals, documents, budgets and schedules after a client is engaged — and its site describes no CRM, accounting or invoicing features. Planify also states that data is hosted exclusively on EU servers, which matters if that is a procurement requirement for you.

NYA — $49 to $299 flat per firm

We build NYA, so read this entry with that in mind. Three plans, all flat: $49/mo solo, $129/mo for up to five people, $299/mo unlimited. No per-seat fees at any tier, client access always included, no minimum term, 7-day trial, cancel anytime. The trade-offs are stated in our comparisons: no lead marketplace, and books export to QuickBooks or Xero rather than living in-app.

DesignFiles — $55 or $75, plus $30 a user

Two tiers, both published: e-Design at $55/mo and Full Service at $75/mo, each +$30/mo per additional user. The e-Design tier is the lowest published entry point in the category after NYA. Five people on Full Service: $195/mo.

Mydoma — $58 a user, plus an onboarding fee

A single plan at $58/user/mo on annual billing, with a $300 mandatory onboarding fee on top — the only vendor here that charges to start. Mydoma has been part of Studio Designer since July 2024; it still sells standalone, but its pricing page steers accounting-minded buyers to its per-user parent.

Studio Designer — $69 to $119 per user

Per-user tiers at $69/$79/$109 on annual billing ($79/$89/$119 month-to-month). What you get for the model is real double-entry accounting inside the project tool — the genuine differentiator no flat-priced product replaces. What you pay for it: $207/mo for three Essentials seats, $345/mo for five.

Programa — $71 plus $31 a seat, currency unstated

Pro at $71/mo first seat + $31/mo per extra seat on annual billing; month-to-month is $89 + $39. Two footnotes worth knowing: the advertised rate is the annual one, and the pricing page shows a bare dollar sign without stating the currency — AUD, GBP and EUR rates differ.

Design Manager — $79 a user, with no tiers at all

One rate for everyone: $79/mo per user, and its FAQ confirms every user costs $79, with teams above ten directed to sales. Accounting, purchasing, specifications, time billing and online payments are all inside that price, which makes it the simplest bill in the category to forecast — five people is $395/mo. Two things sit outside it: the showroom and data collection modules carry an unpublished extra fee, and the FAQ states the product is optimized for US-based firms. Our full breakdown works through the seat maths and trial terms.

Gather — $99 or $199, plus $39 a seat

Spec Lite at $99/mo and Spec Pro at $199/mo, +$39/mo per extra seat. Specification-first software: strongest for FF&E schedules and procurement rather than proposals and client portals. Because the seat rate is identical on both plans, the gap between them stays $100/mo at any team size — see the full Gather pricing breakdown.

Houzz Pro — $249 plus $60 per extra user

Houzz Pro publishes Pro at $249/mo after a 30-day trial, with one seat included and additional users at $60/mo. Five people total $489/mo before advertising, which starts at $499/mo. Custom remains quote-only, and the trial page states a 12-month minimum contract. Our full breakdown keeps the current first-party figures separate from older aggregator prices.

The number that actually matters is cost at your team size

Entry price is a poor guide because the billing models diverge as a team grows. Planify stays at one flat annual-billing rate, NYA stays flat inside each team-size tier, and the remaining published-price products bill again for each person you add.

What that means over a year

• Solo: Planify $293.88/yr, NYA $588/yr, DesignFiles e-Design $660/yr, Mydoma $696/yr + $300 onboarding, Studio Designer Essentials $828/yr, Programa $852/yr.
• Three people: Planify remains $293.88/yr, NYA $1,548/yr (Studio plan), Programa $1,596/yr, DesignFiles Full Service $1,620/yr, Studio Designer Essentials $2,484/yr.
• Five people: Planify remains $293.88/yr, NYA remains $1,548/yr, DesignFiles $2,340/yr, Programa $2,340/yr, Studio Designer Essentials $4,140/yr — and $6,540/yr on Premier.
• All twelve-month figures are the monthly rates above × 12; Mydoma's onboarding fee is one-time. None include payment-processing costs or Houzz Pro advertising.

Watch for the costs that are not on the pricing page

• Contract length. Houzz Pro's free-trial page states a 12-month minimum term.
• Onboarding and migration fees. Mydoma charges a $300 mandatory onboarding fee; ask every vendor what setup actually costs before you sign.
• Payment processing margin. Some platforms mark up card and ACH fees above cost — worth checking if you collect client payments in-app.
• Advertising, which is a different product from software. Houzz Pro lists advertising starting at $499/mo.
• Billing-cycle gaps. Several vendors advertise the annual rate: Programa is $71 + $31 annual but $89 + $39 month-to-month, and Studio Designer's tiers rise $10 each on monthly billing.
