Features
thesheet tools.
That change how you work.
thesheet is built specifically for interior design specs — not a generic tool adapted to fit the work. Save hours, not minutes — on every single project.
The argument
New client. Same chaos.
Sounds familiar?
We built thesheet because great designers were spending their best hours fighting with spreadsheets. Not because Excel is bad — it's a brilliant tool. Just not for this.
This is a thesheet spec sheet
Simple on purpose.
Serious about the work.
thesheet starts just as simply as opening Excel.
What you get out of it is a different story.

Client approvals & feedback
Share a project your clients can actually review
Clean, mobile-friendly project link instead of another PDF or Excel. Clients can comment and approve without downloading anything or even logging in.
You stay in control of what is ready to share and what should stay inside the studio.
No formulas. No surpises.
The budget that updates every time a product does
Add a product, change a quantity, swap an alternative — the total updates. No formula to break, no rebuilding the calculation when something changes.
Add your supplier discounts and client markup and thesheet handles the rest. No separate Excel to find out where you stand.

Good questions
Answers to common questions about getting started and using thesheet day to day.
What is a spec sheet in interior design?
A spec sheet is the document that holds everything together on a project — every product selected, with its dimensions, finish, supplier, price, and status. It's what designers share with clients for approvals and with contractors for installation. In most studios, it's still built in Excel. thesheet is software built specifically to replace that.
Is thesheet really free?
Yes. The Solo plan is free with no time limit — run up to three active projects, use the Web Clipper, share with clients, and build your product library without paying anything. When you need more projects or want Studio features like custom branding and advanced sharing controls, the Studio plan starts at €35 a month.
I already have projects in Excel. Can I bring them in?
Yes — thesheet supports direct XLSX import, so you can bring your existing spreadsheets in without starting from scratch. If you also have saved product links in browser bookmarks or Google Docs lists, you can import those URLs straight into your library too. Most designers set up their first project in about three minutes. The Web Clipper also makes adding new products fast enough that many designers find it easier to start fresh than migrate old files.
How does client sharing and approval work?
You share a link. Your client opens it on any device — no account needed, no app to download — and sees a clean, visual version of your spec. They can browse products, leave comments on individual items, and approve or reject with one tap. Works just as well on mobile as desktop, which matters since most clients will open it on their phone. On Studio, create separate links for different recipients, each showing only what's relevant to them.
How is this different from managing projects in a spreadsheet?
A spreadsheet is a blank grid you spend hours formatting before you've added a single product. thesheet handles product images, dimensions, pricing, supplier details, statuses, and client communication out of the box — no setup, no formatting. The output looks like something a professional studio produced, not something built in Excel on a Sunday afternoon.
