Every purchase has a witness.
Shahidi Box keeps your signed eTIMS receipts the moment the till issues them. Nothing to scan, photograph or lose.
What we are here to do, and where we are heading.
To make sure everyone who pays for something in Kenya keeps a private, unchanged and lasting copy of the signed receipt, without scanning, typing or losing anything.
We do it by sending each signed eTIMS receipt to its owner as soon as the till issues it, sealed with a key that only the owner holds.
A Kenya where every purchase has a witness.
Every signed receipt reaches its owner by itself. Every shop, large or small, can send one. And what people buy stays their business, because only they hold the key.
The receipt finds you. You do nothing.
Four stages, from the till to your box. Choose a stage to see what happens, what you do and what happens behind the scenes.
The till issues a signed receipt, as it always does.
Nothing changes at the counter. The shop’s POS creates the eTIMS receipt, signed through KRA, and gives it to you as it does today. That receipt stays the official record.
- It carries the KRA control unit details, the invoice number and the QR code
- The shop does not change how it sells, signs or reports to KRA
- The POS adds one request to its sale, to send a copy to Shahidi Box
- Nothing for the buyer to install, scan or fill in
Shop and pay as you always do. Give your phone number, email address or KRA PIN, or show your Box code, if you want the receipt to find you without a code.
The POS issues the signed receipt and prepares one request to Shahidi Box.
The receipt finds its owner.
Right after the sale, the POS sends a signed copy to Shahidi Box. We match it to its owner without keeping their phone number, email address or KRA PIN in the clear.
- The request is signed by the POS, so only that shop’s till can post for that shop
- Every request carries a unique key, so a retry after a weak connection never makes a duplicate
- A match is made by KRA PIN, phone number, email address or Box code, or by a short claim code on the receipt
- If nobody matches, the receipt waits privately, sealed, and is deleted after 90 days
Nothing, if you gave your number or PIN. If not, type the claim code into the app.
We compare one-way fingerprints and match the receipt to its owner.
It is sealed with a key that belongs to you.
Before anything is stored, the receipt is encrypted with your key. What we keep is the sealed copy, and nothing else.
- You set up your key, and a recovery key, when you open your box
- Receipters staff cannot read your receipts, and a copy taken from our storage cannot be read without your key
- Every connection uses TLS, and stored data is encrypted on disk as well, on top of your own key
- A one-way fingerprint of the original shows if a stored receipt is ever changed
Once, when you open your box: set up your key and a recovery key, and keep the recovery key safe.
We encrypt the receipt with your key and store only the sealed copy.

Only you can open it
What you bought, where and for how much, and your tags and notes, are readable by you alone. Receipters staff cannot read them, and they are never shown to advertisers or to other members.
Locked before it is stored
Each receipt is locked with your own key before it is stored, and every connection to Shahidi Box uses TLS. Stored data is also encrypted on disk, on top of your key. We keep a sealed copy, not a readable one.
Hidden where it matters
Card numbers are never stored in full, and a phone number shown on a receipt is masked. The details we use to match a receipt, such as your phone number, email address and KRA PIN, are kept only as one-way fingerprints that cannot be turned back.
Your receipts say a lot about you. We cannot read them.
Shahidi Box is built so your data is encrypted and masked, and the keys are yours. Receipters keeps the box. You keep the key.
Sealed on arrival
Each receipt is encrypted with a key that belongs to you the moment it arrives. We store only the sealed copy.
Masked by design
Phone numbers, email addresses and KRA PINs used for matching are kept as one-way fingerprints. Card numbers are never stored in full.
You are in control
Share one receipt with a link that expires. Export everything. Delete a receipt, or your whole box, at any time.
Never sold
No advertising, no profiling, no sale of data. A receipt nobody claims is held sealed, then deleted after 90 days.

Straight answers
What is Shahidi Box?
Shahidi Box is a private vault for signed eTIMS receipts. When a till issues a receipt, the POS sends a copy to Shahidi Box, which seals it with the owner’s key and keeps it in the owner’s box. Shahidi is Swahili for witness.
Does Shahidi Box replace the KRA receipt?
No. The receipt the till issues is still the official one. Shahidi Box keeps a faithful copy, with the signature and QR code from the original, so you always have it.
Is Shahidi Box approved by the Kenya Revenue Authority?
No. Shahidi Box is an independent product of Receipters Technologies Limited. It is not affiliated with, or endorsed by, the Kenya Revenue Authority. eTIMS is a KRA system, and Shahidi Box builds on the receipts it produces.
Is it open to the public yet?
Not yet. We are building the product and inviting people from the early-access list, in stages, before we open to everyone.
How do I open my box?
When we invite you, we email you at the address you gave. You set up your key and a recovery key, and your signed receipts begin to arrive.
How does a receipt find me?
The shop can send it with your KRA PIN, phone number or email address, or scan your Box code. If none of these is known, the receipt carries a short claim code you can enter in the app. Receipts we cannot match wait privately and are deleted after 90 days.
Does it work for cash, M-Pesa and card?
Yes. Any sale that gets a signed eTIMS receipt can be kept, whatever the payment method. The method is recorded with the receipt.
What is kept with each receipt?
The receipt exactly as the till issued it, plus a Shahidi Box ID and a fingerprint that shows if the original ever changes. Your own tags and notes sit beside it and never alter it. The full list is in the section “What is kept” above.
Who can see my receipts?
You, and anyone you choose to share a receipt with. Receipts are sealed with a key that belongs to you, so Receipters staff cannot read them.
What can Receipters see?
That a receipt arrived and when, so we can deliver it. We cannot see what you bought, where, or for how much. The name and email you give us when you create an account are visible to us, because we need them to reach you.
What if I lose my phone or my keys?
You set up a recovery key when you open your box, and it opens your receipts on a new phone. Because we cannot read your receipts, we cannot restore them without it, so keep the recovery key safe.
Can I delete everything?
Yes, at any time. Delete one receipt or your whole box, and it is removed from our systems within 30 days, including backups. To be removed from the early-access list, write to receipters@receipters.com.
What will it cost?
Joining the early-access list is free and never asks for payment details. We will publish pricing before Shahidi Box opens, so you can see it before you decide.
My shop uses a different POS. Can I still use it?
We are starting with pilots on DukaPOS and ChomaPOS. Any POS can connect, so ask your shop to write to receipters@receipters.com.
How does a POS connect?
With one request after each sale, signed by the POS. Every request carries a unique key, so a retry never creates a duplicate, and a refund attaches to the sale it reverses. Write to us and we will send the integration details.
Where are the privacy notice and the terms?
Read the privacy notice, the terms and conditions, how we protect receipts and legal and compliance.
How do I contact you?
