Products
Ready to use today
One account and one balance for all five products. Use one or all of them — a payment can trigger an SMS receipt without extra code.
HashBack
Hash decodingM-Pesa C2B callbacks arrive with the payer's number hashed. HashBack turns the hash back into a phone number so you can match the payment and send a receipt.
- Fast enough to use inside a live payment flow
- Pay as you go — failed decodes are not charged
- Kenyan numbers (Safaricom and Airtel)
HashSMS
Bulk SMSSend to one number or a hundred thousand, under your own sender ID once it is approved.
- Templates and contact groups
- Delivery report for every message
- REST API for sending from your system
B2C payouts & disbursements
PayoutsPay staff, suppliers and riders straight to M-Pesa from one balance — one person at a time or a whole payroll at once.
- Upload a payroll file and run it
- Bulk B2C payments with float management
- Every payout reconciled, with its own receipt
WhatsApp Business API
MessagingOTPs, payment receipts, delivery updates and support replies on the app your customers already use.
- OTPs and transaction notifications
- Same API shape as SMS — switching channel is a small change
- Built on the WhatsApp Cloud API
B2B & card payments
Coming soonPay other businesses from your wallet — till, paybill and bank — and accept Visa and Mastercard on the same checkout as M-Pesa.
- B2B transfers from your wallet
- Card and M-Pesa on one checkout
Your dashboard
Every payment and message in one place
While your customers and staff see an M-Pesa prompt or a text, you see it land: STK payments, payouts, wallet top-ups and bulk SMS delivery, on whichever device you have to hand.

Solutions
Systems for specific industries
These are built around your operation rather than signed up for online. They run on the same payments, messaging and wallet services as our products.
POS & Retail
Shops, supermarkets, restaurants
Cash and M-Pesa get recorded in different places, stock counts drift, and closing the till takes too long. Our POS takes M-Pesa at the counter, tracks stock as you sell, sends or prints receipts, and closes the day with a report that matches the money received.
Transport & Fleet
Matatu operators, logistics firms, delivery fleets
Daily collections come in from many vehicles and drivers, and it is hard to see who has paid what. We put vehicles, drivers, routes and collections in one system, with driver payouts and SMS alerts handled by the same platform.
Rentals & Property
Landlords, agents, property managers
Rent reminders, arrears and landlord payouts are usually tracked by hand. We build listing platforms for finding a house, and management systems for running one — tenants, units, rent collection with automatic reminders, and payouts.

Why HashBack
We run what we build
HashBack Solutions is a Kenyan software company. We operate our own payments and messaging services in production, and the custom systems we build for clients use the same code.
Projects follow a fixed process — discovery call, written proposal, design, development in short sprints, testing and launch.
How we work- Built for Kenya
- M-Pesa callbacks, USSD flows, patchy connectivity and local rules are things we deal with every day.
- Security by default
- HTTPS everywhere, encrypted data at rest, CSRF protection and careful API key handling.
- Clear delivery
- Agreed milestones, regular demos, a staging environment and version-controlled code you own.
- Support after launch
- Maintenance, monitoring and new features on a retainer, from the people who built it.

We outsourced Hasback Solutions. to develop a system for managing our parcels, fare collections, luggage expenses, and user management, and they did an excellent job.
