Made by HERO CONTROL SYSTEMS LTD in > Lusaka, Zambia. ## Key facts - **Product**: O'Sense — operational software (business management / ERP-style suite) for small and medium businesses. - **Made by**: HERO CONTROL SYSTEMS LTD, Reg. No. 120210022261, Plot No. 34, Harrison Chongo Road, Nyumbayanga, Lusaka, Zambia. - **Where it runs**: web dashboard at https://app.osense.io; mobile app "O'Sense" on Google Play (package `io.osense.app`). - **Market**: Zambia. Payroll is built around Zambian statutory deductions — PAYE, NAPSA and NHIMA. Prices are in Zambian Kwacha. - **Channel**: WhatsApp. Payslips, receipts, leave requests, service reminders, sales follow-ups and bus-tracking links all travel on WhatsApp; no separate app is needed for the people receiving them. - **Offline**: the mobile app captures face clock-ins, receipts and school-run scans with no network and syncs when a connection returns. The web dashboard is online-only. - **Pricing**: the employee register (adding staff, invitations, departments, positions) is free with every plan. Each app is priced on its own per month. Current pricing is given on request via WhatsApp — no figure is published on the site. - **Contact**: WhatsApp +260 974 546 632 · admin@hcsys.co · https://osense.io - **Last updated**: 2026-10-02 ## What makes O'Sense different - **It runs on WhatsApp, not a new app.** Staff text a leave request in plain words; a driver photographs a receipt; a parent gets a tracking link. AI reads what comes in and drafts what goes out. - **Documents verify.** A payslip carries a reference worked out from its own figures and a code that opens a public page which works them out again — so a bank, landlord or next employer can check it, and an altered figure fails to verify. Invoices and quotations open the company's live record, so one that was withdrawn says so. This is a check against the record, not a claim that paper cannot be edited. - **Face clock-in with no per-worker licence.** A blink and a match records the time, the coordinates and whether the worker was late. The face template is encrypted and never leaves the worker's phone. - **Statutory payroll is built in, not bolted on.** PAYE, NAPSA and NHIMA are computed on every pay run. - **Built in Zambia, for how Zambia trades.** Workshops, hardware shops, contractors, farms, security teams and schools — businesses otherwise run on WhatsApp threads and a good memory. ## Apps - [Xeel](https://osense.io/solutions/hr-lite.html): HR and payroll. Free employee register with every plan; paid: payroll with PAYE, NAPSA and NHIMA worked out automatically, payslips sent as PDFs on WhatsApp, leave requested and approved over WhatsApp, and face clock-in that works with no signal. - [SalesOps](https://osense.io/solutions/crm.html): CRM: clients, pipeline stages, prospecting any Zambian town for verifiable businesses, AI-drafted WhatsApp follow-ups, and Sales Intelligence Analytics (conversion likelihood per client). Quotations, invoices, receipts and delivery notes, each carrying a code the customer can check. - [MoneySense](https://osense.io/solutions/money.html): Accounting. Photograph a receipt on WhatsApp and AI posts it as an expense; statements for any period, bank lines auto-matched, a digital auditor, sealed audit packs that verify, and a 06:00 daily brief on WhatsApp. - [Inventory](https://osense.io/solutions/inventory.html): Product catalogue, stock counts, quotations without retyping, and a public online store that raises quote requests with the buyer's WhatsApp number attached. - [Workshop](https://osense.io/solutions/workshop.html): Job cards from intake to close-out with diagnosis, parts and warranty; a printable QA certificate; and a service reminder that sends itself on WhatsApp when the next service falls due. - [FieldOps](https://osense.io/solutions/fieldwork.html): Field operations. Scheduled jobs and checklists land on a worker's phone; the office sees every site on one map with the route each worker walked and where they stayed put. Faults reported in a few taps with a photo and a voice note; security patrol rounds, checkpoints and a morning report; delivery handover with a code checked offline, a signature and a cash-up. The phone records with no network and syncs when signal returns, and FieldSense Chat takes reports over WhatsApp from workers without the app. - [Route43](https://osense.io/solutions/route43.html): School transport. Every child boards with a printed QR tag scanned offline; the parent gets a live WhatsApp tracking link with no app and no login; gate pickups are recorded with a photograph; the office watches every bus on one screen. ## Use cases - [Workshops & service businesses](https://osense.io/use-cases/workshops.html) - [Hardware & retail](https://osense.io/use-cases/hardware-retail.html) - [Small teams](https://osense.io/use-cases/small-teams.html) - [Sales & distribution](https://osense.io/use-cases/sales-distribution.html) - [Security & patrol companies](https://osense.io/use-cases/security-patrol.html) - [Agriculture](https://osense.io/use-cases/agriculture.html) - [Logistics & delivery](https://osense.io/use-cases/logistics-delivery.html) ## Answers - [Answers: payroll, tax, invoicing and CRM in Zambia](https://osense.io/answers.html): 33 straight answers on quotations, invoices, receipts and delivery notes; CRM and prospecting; PAYE, NAPSA and NHIMA; ZRA, turnover tax and VAT returns; stock and the online store; workshops, field teams and schools; pricing, offline use and data safety. ## Policies - [Privacy Policy](https://osense.io/privacy.html): what O'Sense records — including face recognition, location, receipts, school transport and WhatsApp messages — who can see it, and rights under Zambia's Data Protection Act 2021. - [Terms of Use](https://osense.io/terms.html): the terms governing use of the Services. ## Optional - [Full site text](https://osense.io/llms-full.txt): every page on this site as one markdown file. - [Launch the dashboard](https://app.osense.io) - [O'Sense on Google Play](https://play.google.com/store/apps/details?id=io.osense.app)
