About the project

Core is a business management system I am designing and building on my own. It brings finance, sales, stock, tax documents, projects and people into one product, so a small or mid-sized company can run its day without jumping between spreadsheets and disconnected tools.

What it is

A system for running a company from end to end: money coming in and going out, sales, purchases, stock, production, tax documents, projects, the sales pipeline and the team. Everything shares the same data, so a sale updates the stock, the invoice and the cash flow without anyone typing it twice.

Accounting overview with cash, receivables, payables and the result for the year
Bank reconciliation with statements and matched entries

The idea

Management systems are powerful and tiring. Screens are crowded, every task hides behind menus and new people take weeks to feel at home. The idea behind Core is the opposite: keep the depth a company needs and make each screen answer one question clearly, such as what is due today, what is waiting for my approval or how the month is going.

The accounting reports: balance sheet, income statement, cash flow and ageing
The sales pipeline as a board, with deals moving from stage to stage
Stock overview with balances, movements and items to replenish

The proposal

One product for every area, with the same patterns everywhere. Someone who learns to register a sale already knows how to register a purchase, a task or an employee. It also follows how companies work in Brazil, with tax documents, tax calculation and the reports accountants ask for, and it lets each company adapt forms, reports and colours to its own way of working without calling a developer.

The tax area with invoices, tax calculation and the official tax file
A project schedule with dependencies, the critical path and conflicts to solve
The point of sale screen with products, the cart and payment
The people area with employees, time off and payroll summaries
The approvals inbox: each request with its amount, requester and history
The report builder, choosing columns, filters and groups

The goal

Give smaller companies the control large ones have, without the cost and the learning curve that usually come with it. Core is still in development: the screens here come from the working product, filled with fictional data, and each area is being refined with real routines before launch.
