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 Personal plan is free with no time limit — run one project, use the Web Clipper (limited to 5 a day), share with family members without paying anything. When you need more projects or want Studio features like 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.
