Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

Hi, I am Lei, the developer of Renpavo. It is a free change-order worksheet that runs in your browser. You can price added and removed work separately, choose the markup base, then export PDF, Word, Excel or CSV.
The public CO-003 example is fictional: $5,149 in additions minus $1,648 in credits gives $3,501 net cost. At 12% markup on net cost and $112.14 optional tax, the change is $4,033.26. Tax and markup treatment must follow your own contract and jurisdiction.
It provides printable signature lines, not electronic approvals, delivery tracking or a cloud project-management system. Drafts are local, so export a copy for your records.
For contractors reviewing it: are additions, credits and the markup base easy to audit? Which field or export would make it more useful in your workflow?
