Quotes you can compare. Offers they can accept.
Send a quote request or publish a priced offer — either way, the other side answers from an email link, with no account to create. Every quote, offer and purchase order lives in one file you own.
30 days of the Solo tier. No charge. No commitment.
Suppliers answer by email link
Invite them from your contacts. They price the lines and submit — nothing to sign up for.
Compare quotes line by line
Normalized totals make the differences visible. Award the purchase order without leaving the file.
Sell the same way you buy
Publish a priced offer. Your customer opens a link and accepts — and their order lands back in the same file.
How it works
One yearly price covers your whole business. The other side always answers for free — and payment for the goods stays between you. kanpo is the deal file, not the bank.
When you buy
Ask for quotes
Describe what you need; send each supplier a request by link.
They answer, no account
Suppliers price your lines and submit from the link you sent.
Compare and award
Answers line up side by side; the winner becomes a purchase order.
- Change a live request and earlier answers are marked out of date until the supplier replies again.
- Log the call or email that arrived anyway, so the file shows the whole market.
When you sell
Publish an offer
Turn your price list into a dated offer, terms and validity included.
They accept from the link
Your customer opens it, checks it, accepts. No account, no password.
Pro forma, on record
Issue the pro forma from the same file; the order stays recorded.
- Clarify the specification on the document itself — a question-and-answer thread, not a lost email chain.
- Answer a buyer's request once and the offer is saved in your own book.
Both directions end in the same place: one purchase order, its documents attached, in a file that stays yours.
Pricing
A flat yearly price for the whole business. The people answering you never pay, and the documents you send are never metered.

How ordering works
You place a purchase order from your Billing page; OVERBRING Labs invoices once for the year. No card details, no automatic charges.
After the first 30 days
Nothing locks. Your history, what other people sent you and the portals stay open — creating or sending new documents is what waits until you pick a plan.
