What it costs
The cost is one tidy list. If your customers live in a notebook, you type them in once.
What owners do today
Your customer list lives in a spreadsheet, a notebook or your phone contacts, not in field service software.

- Save the sheet as CSV.

Not ready to export yet? Try the preview with a sample file. No file of yours is needed.
The preview reads your file in your browser, on this page. The page does not upload it or send it anywhere. To check, open your browser's developer tools, go to the Network tab, and drop the file: you should see no request carrying it. We ran that check with an automated browser on the build of November 10, 2026. We have not run it on the live site, or with browser extensions you may have added.
CSV only, up to 5 MB. The first row should name the columns.
The preview is a look at your file, not the import. When you import in CONSTRUKTR, you check the preview there, and nothing is saved until you confirm.
CONSTRUKTR does not connect to your old software and pull your customers across. You export a file, then drop it in.
