Keeps trading offline
Connections fail. Sales do not stop. Invoices queue locally and transmit themselves once the link is back, with nothing to re-key.
What we build
A product, and the plumbing behind it.
Some businesses want a point of sale that handles compliance for them. Others want the system they already run to start filing correctly. We do both, and we wrote all of it ourselves.
Our product
Sell, print, file. One action.
INJONGE is our own point-of-sale and electronic billing system. The cashier rings up a sale; the receipt prints with the authority's signature block already on it; the invoice is filed. There is no second system to reconcile against at the end of the day.
INJONGE
Built for many branches
Tills, branches and warehouses report into one back office. Pricing and stock are set centrally and pushed out.
Stock and purchasing included
Items, batches, expiry, suppliers, purchase orders and stock counts, because an invoice is only as good as the item file behind it.
Reporting that reconciles
Z-reports, shift reports and tax summaries that agree with what the authority has actually received.
Runs on your hardware
Terminals, tablets and desktop tills. If you already have hardware we will usually work with it; if not, we supply it.
Languages that fit the market
Deployed in English and French across the countries we serve.
Integration services
Keep the system you have. Make it file correctly.
This is the larger half of our work. You have an ERP, a POS, an accounting package or something written for you years ago, and it has to start talking to the revenue authority. We build that connection.
ERP and accounting systems
We connect established ERP and accounting estates to the authority without asking you to change how your finance team works.
Third-party and legacy POS
Tills that were never designed for fiscalisation, brought into compliance through our middleware rather than replaced.
In-house and bespoke software
Systems written specifically for your business. We work against whatever interface they can offer — database, file drop, or API.
Multi-country estates
One business trading across several of our markets, integrated once, with the per-country differences handled inside the middleware.
API & middleware
What actually sits between you and the authority.
The connector is the part nobody sees and everybody depends on. Here is what ours is responsible for.
-
Mapping
Your data is not shaped the way the authority wants it. The middleware translates items, tax classes, customers and totals into the required format.
-
Signing and transmission
Each invoice is signed and sent, and the authority's response is captured and written back so the receipt can carry it.
-
Queuing and retry
Timeouts, dropped connections and authority downtime are handled by queuing and retrying rather than failing the sale.
-
Reconciliation
Everything sent is logged against what was acknowledged, so a gap is something you can see rather than something you discover at audit.
Beyond fiscalisation
The rest of what we build.
Rhenium was an integration and payments engineering firm before it was a fiscalisation one. That work continues, and it is where the discipline came from.
- Custom software development. Financial services, transaction processing, terminal-based systems and mobile applications, designed and built in house.
- Gateways and ISO bridges. Interfacing systems to remote hosts — multiplexing connections, handling timeouts and reconnection so messages are not lost.
- Terminal-based solutions. Payment and distribution applications on POS terminal hardware, through long-standing hardware partnerships.
- Bulk payments. Mass payment and collection runs over mobile money channels, with reconciliation and alerting built in.
Support
Going live is the start, not the finish.
Specifications get revised, authorities add requirements, and businesses open new branches. An integration that is not maintained quietly stops being compliant.
- We track specification changes and update your integration
- Support in your time zone, in the language you work in
- Help with the authority's onboarding and testing process
- Training for the people who actually use the system daily
- New branches and new tills added without a fresh project
What to send us
To give you a straight answer quickly, it helps to know:
- Which country or countries you trade in
- What system you run today, if any
- Roughly how many invoices you issue a month
- How many branches and tills
- Whether you have started with the authority already

A demo with your items, your tax classes and your invoice shapes tells you far more than a slide deck does.
