"I sent the money. He says he never got it. I have an M-Pesa screenshot. He says it was for something else."

M-Pesa screenshots are not proof. They can be faked. They don't say what the payment was for.

WhatsApp agreements are not binding. Screenshots can be cropped. Context disappears.

Verbal deals leave no record. Memory fades. Stories change. Nobody can prove what was agreed.

How it works

Five steps.
One permanent record.

Create

Tell Nana what the deal is on WhatsApp.

Send

Nana sends the document link to your counterparty.

Confirm

Both parties enter a one-time PIN to confirm they agree.

Lock

The document is cryptographically sealed. Forever.

Verify

Anyone can scan the QR code to verify the document is real.

Beyond the document

Proof that follows you.

A locked document proves one deal. Do enough of them, and something bigger builds: a track record. Every agreement you honour becomes part of a history other people can see and trust — and every broken promise is on record too.

Nana can't force anyone to pay or deliver. What it can do is make sure the people who decide — buyers, sellers, even a lender — can see the truth before they act.

Strong track record — safe to proceed

Free dispute filing on every plan. Your history is yours — share it, and it opens doors.

KRA-ready

Your invoices & receipts,
eTIMS compliant.

Kenyan traders have tax obligations on every sale. Nana calculates the applicable taxes automatically and shows them clearly on your invoices, receipts, and other documents — so the record you lock is also a record that reflects what's owed. You always know where you stand, without a separate system or an extra step.

eTIMS-ready — you know your obligation on every deal

Nana calculates and displays applicable taxes to help you meet your obligations. It does not file or report anything to KRA on your behalf, and is not affiliated with KRA or the Government of Kenya.
