ZRA Smart Invoice integration

Fiscalised sales from the same transaction used by finance.

We run this in production every day. Invoices are signed and transmitted to the VSDC, the fiscal code and QR come back and are stored against the document, credit notes and voids are handled to spec, and anything that fails queues and retries instead of disappearing.

Who it is for

Businesses that must fiscalise but do not want to replace the software they invoice from.

  1. 1Transmission with the fiscal code and QR stored on the invoice
  2. 2Credit notes, voids and corrections handled properly
  3. 3Retry queue with a screen showing anything stuck
  4. 4VAT schedules that reconcile to what was actually transmitted

Kora Website Builder

A website built from a conversation, then edited by message.

Kora interviews you on WhatsApp or the web, writes a design language for your brand instead of filling in a template, produces the copy and the catalogue, runs its own visual checks and deploys. Afterwards you change it by sending a message.

Who it is for

Businesses that need a real website this week and will never log into a dashboard to maintain it.

  • Conversational briefing on WhatsApp or the web
  • A design language generated for your brand
  • Copy, pages and product catalogue written for you
  • Live edits by message, version history and rollback

WhatsApp Insurance Agent

Quote, take payment and issue cover, inside the chat.

The agent gathers the risk details, rates the cover with the statutory levy, takes mobile money, issues the certificate and files it, for motor, home, travel, medical, business and liability. It hands over to a person the moment its confidence drops.

Who it is for

Brokers and insurers whose customers already message rather than call.

  • Rating for your products, with levies and fees computed
  • Mobile money collection and receipting
  • Certificate and policy documents issued automatically
  • Human handover, transcripts and an audit trail

AI agents & automation

Agents that do a job end to end, not chatbots that answer questions.

We scope one job and automate it completely: matching transactions against bank feeds, reading invoices and delivery notes into your system, resolving support tickets, or moving work between systems that do not talk. Built against your data, with explicit rules for when a person takes over.

Who it is for

Teams losing days to reconciliation, re-keying, document handling or first-line support.

  • One job scoped, built and measured
  • Escalation rules so nothing is guessed at
  • Operator console with transcripts and overrides
  • Accuracy measured against a labelled sample before go-live

Custom software development

Systems built for your operation when nothing off the shelf fits.

Full-stack engineering: internal platforms, customer portals, marketplaces and multi-tenant products. We start from how the work actually happens: who does what, what gets approved, what must never be lost. Then we build around it.

Who it is for

Businesses whose process is the advantage and should not be bent to fit a product.

  • Working software in staging from the second week
  • Roles, permissions and audit trail from day one
  • Payment, SMS, WhatsApp and API integrations
  • Handover documentation and admin tooling

Mobile app development

Native iOS and Android apps, designed, built and shipped to the stores.

We take a mobile product from idea to the App Store and Play Store: interface design, the app itself, the APIs behind it, payments, notifications and analytics. Built to feel native on both platforms, tested on real devices, and shipped with the release pipeline and monitoring already in place.

Who it is for

Businesses that need an app their customers or staff actually use, not a wrapped website.

  • Product design and interface prototyping
  • iOS and Android from one codebase
  • APIs, payments and push notifications
  • App Store and Play Store submission
  • Offline handling and background sync
  • Crash reporting, analytics and updates

Hosting, support & maintenance

The people who built it keep it running.

Hosting, monitoring, backups that are actually restored on a schedule, security updates, and a support queue you can see. Monthly reporting on what changed, what broke and what it cost, with a standing budget for improvements.

Who it is for

Every client we ship for, and systems built by someone who has since disappeared.

  2. 2Agreed response and resolution targets

How it runs

Four stages.Each one ends in something you can use.

Discovery

We sit with the people doing the work and map what happens today, every form, approval and spreadsheet in between. Priced separately, and the map is yours whether or not we build.

Build

Delivered in increments, each one ending in something you can actually use rather than a status update. Priorities can change between increments, not inside them.

Launch

History migrated and reconciled, staff trained on their own data, and the cutover rehearsed before the day it happens.

Run

We host it, watch it and keep improving it, with a regular report on what changed and what it cost.

Tell us what is not working.We will tell you what it takes.

If an existing module already does it, we will say so. That is cheaper for you and faster for us than building it again.
