Repeatwise changes the prices on all the repeating invoices in your Xero organisation at once. It shows every line before and after, saves a copy of every original, and lets you undo the whole job for 30 days. The scan, the preview and the CSV export are free, as are the first 5 templates you change in each organisation. You sign in on Xero's own page, so Repeatwise never sees your Xero password.
