If you need a system built.
Zyntlow is a software development company. We build operational software for people and organisations — tills, ledgers, storefronts, the whole stack. Maintenance of something already running is available; it is not the default. If the system does not exist yet, that is the conversation this page is for.

What to include
- Who you are — a person, a shop, an institution — and what the business actually does.
- What you need built, even if nothing exists today.
- If there is existing code, say so; if you are starting from nothing, say that too.
- Rough timeline and whatever budget shape you have.
Engagements
Build a system
A product that does not exist yet — schema, API, client, packaging and deploy. People and organisations come here to have the thing built, not to hire a caretaker for someone else’s code.
Architecture review
A platform that works but is getting harder to change. Offline strategy, multi-tenancy, data model, sync correctness.
Operational interfaces
Dense internal tools people use all day: keyboard-first flows, tables that hold up at scale, design systems that survive sixty screens.
Strongest ground
Named problems, with something live you can open. That is the difference between a pitch and work already in production.
A till that keeps selling when the network drops
Inventory, point of sale, credit and purchasing for shops and wholesalers. Offline is the default, not a feature flag.
tallyhubgh.comBooks that balance for a savings-and-loans
Double-entry ledger, cash desk, loan book and the returns a supervisor asks for. The Bank of Ghana transition closes 31 December 2026.
kernvo.comA shop that takes mobile money
Catalogue, honest delivery pricing, Paystack MoMo, and an admin the owner runs. For retailers still losing orders in a WhatsApp thread.
tresoriabeauties.comCustomers on feature phones
USSD session flows and mobile money collection that treats payment as asynchronous — pending, signature-verified, then stock or balance moves.
USSD and mobile moneyOut of spreadsheets, or off a vendor who stopped answering
Extraction, reconciliation and a batch import that can be rolled back. History intact, plus a report of what did not survive.
Data rescue and migrationThe engineering underneath
AWS, Google Cloud, Azure — the same clouds those companies sell, plus the data, payments and product surfaces we ship on them.

Call or write
WhatsApp is usually the fastest. Calls during Ghana working hours. The form writes the message down before it tries to send it, so a provider having a bad day does not lose it.
