Custom business applications

Business applications built around how your teams work.

When a spreadsheet has become a process and a report cannot change anything, we build the application: role-based, mobile-first, with hosting and handover terms set in the contract.

What we have built.

Tools that people open every morning, each tied to a real process.

CRM and job management

Buyer matching for real estate, project pipelines for building finishes, a client registry for corporate services.

Quote and pricing engines

Group quotations qualified against capacity, quotes that clients sign online, discount approval workflows.

Operations and stock

Stock by product and shade, a seven-step project workflow, stop-sales grids with a full audit trail.

Ordering and booking

Restaurant ordering and table reservations from a mobile menu, with WhatsApp contact from the order screen.

What you receive.

A custom application should not become a rental.

Code and documentation

Code written for your project, its configuration and its documentation are handed over as the contract provides. Digital Bonsaï keeps its own tools, generic components, frameworks and methods; where one is built into your system, your right to use it is set out in the contract.

Hosting and handover

Who holds the Supabase or Railway account, how it is handed over and how it is run are defined for each project and set out in the contract. Provider fees are often around 50 USD a month.

A stack that follows the problem

Next.js, Supabase and Railway when they fit, Microsoft tools when they fit better.

A way out

You can run it yourselves after training, or ask us to run it.

Systems we have built

Real systems, in production or in delivery. Client names are withheld.

Projects and stock platform

Every site followed from signed quote to final payment, with materials reserved from the quote and stock that stays right.

Constraint. No ERP behind it: the platform is the system of record for projects and stock.

Quotes that sign themselves

Each quote becomes an online proposal the client can sign. The team sees who really read it, and the CRM updates on its own.

Constraint. Quotes were sent as attachments, so nobody knew whether they had been read.

Buyer matching CRM

Each new listing is matched to the right buyers the day it comes in, with a score that explains itself and a daily follow-up list.

Constraint. The agency's transaction software has to stay the source of properties, mandates and buyers.
