Frequently asked questions about Obrarum

Obrarum is construction estimating software for contractors, architects and engineers who work on their own or in small teams. You build the estimate with chapters, items and cost components, check it with Obrarum AI and send your client a link to approve and sign the quote.

Yes. Obrarum has a Free plan that never expires and needs no card. It includes Obrarum AI and client e-signature, so you can try it on a real job. The pricing page shows what Pro and Business add.

Yes. With Obrarum you build, check and send the estimate in one place: you reuse your items, Obrarum AI checks it before you send it, and there's a record of what your client approved. Your spreadsheet doesn't warn you when you get something wrong; Obrarum does. You can export the full breakdown to Excel too.

Obrarum focuses on estimating fast and closing the job with your client, not on running the whole company. With other estimating software it's common to take a course before you start; with Obrarum, contractors, architects and engineers get going without long training and estimate more jobs in less time. There's nothing to install, because it runs in the browser, Mac included. You start on the free plan, and paid plans add more AI features.

No. Obrarum runs in your browser, with nothing to install. Describe the job in your own words, Obrarum AI drafts the estimate and you adjust whatever you need.

Obrarum works for all three. It's made for whoever estimates jobs often and answers to the client for the price: the contractor who builds, the architect who designs or the engineer who runs the job, on their own or with a small team.

Yes. Obrarum works in the browser of any phone or tablet, with nothing to install, so you can build, check and share an estimate from the job site. For long estimates, it works best on a computer.

No. Obrarum AI never sets a price: it proposes items from your library and the Obrarum library, and you decide what goes into the estimate. Obrarum library items are templates with materials, labor and quantities; the costs and margins are yours.

No. The costs, prices and margins in your estimate never reach Obrarum AI. It reads what you write about the job and the names of your chapters and items.

A unit price analysis is the breakdown of what it costs to build one unit of work, like a square foot of wall: its materials, labor, equipment and quantities. In Obrarum, every item in your library and in the Obrarum library carries that breakdown.

Yes. Save an item from the Obrarum library to your library and edit it however you like, with your own prices. Then use it to build your estimates faster.

No. Your client opens the link in their browser, with no account. To approve the quote, Obrarum asks for their full name, ID number and signature. You get a certificate of the approval.

No. Your client only sees the final prices, on the link and on the PDF. Your internal prices and margins are for your eyes only. You choose what else the PDF shows, like quantities or chapter subtotals.

In Obrarum you create a new version of the estimate with everything from the last one, change only what your client asked for and share it with them. The version you already sent stays locked as it was, so you know which quote your client has and which one they approved.

Your client's signature is kept as a record in a certificate you download with the PDF: their name, ID number, signature, the date and the device. That way you know who accepted what and when. What it's worth in a dispute depends on the laws of your country.

Yes. Copy the estimate link and paste it into your client's chat like any other message. Your client opens the quote on their phone, approves and signs it right there, and the approval is recorded in Obrarum.

Per company. You pay one subscription and your whole team shares it. Free includes 1 user, Pro 3 and Business 8, and you can add more on Pro and Business. Every member counts, including view-only ones. To invite your team, create your company's organization in Obrarum.

No. Your client opens the link, approves and signs without an account, so they never take up a user on your plan.

You pay in your local currency if you're in the US, Mexico, Peru, Colombia, Chile, Canada or a European country that uses the euro. Everywhere else, you pay in US dollars. The site shows you the price in the currency you'll pay in, based on the country you're visiting from.

Yes. Every payment comes with a PDF invoice you can download from the Subscription section in Obrarum, with your company name, tax ID and address.

No. Everything you've created stays available. The limit only stops you from adding anything new, like a second project on Free. Move to Pro to keep adding.

Yes. Upgrade, downgrade or cancel whenever you want from the Subscription section in Obrarum. If you cancel, you keep your plan until the end of the period you've paid for. Then your personal workspace moves to Free and your estimates stay as they are, but locked for editing. A team workspace keeps all its data, read-only until it subscribes again.

Obrarum works in any country, in English or Spanish. You choose metric or imperial units for each project, and the Obrarum library converts to them, so you work in the units used where the job is.

Yes. In Obrarum, each tax is an adjustment to the whole estimate: you give it the name used in your country and choose a percentage or a fixed amount. You decide whether your client sees it itemized on the PDF.
