The problem

Your business is scattered across tools that don't talk to each other.

One app for invoicing, another for stock, the website on its own and everything else in spreadsheets and chat. You lose hours moving data between them and never get a clear picture of how the business is doing.

  • The same data typed three times into three different places
  • Nobody knows which version of the spreadsheet is the real one
  • Working out how the month went means adding it up by hand

What's included

Your whole business on one screen.

/01

Sales, orders and expenses

Quotes, orders, sales and expenses in one flow, with the status of everything always in view.

/02

Customers and suppliers

The full record, history and contacts in one place — no digging through a thousand emails.

/03

Stock and inventory

Stock that updates itself with every sale and purchase, with low-stock alerts.

/04

Built-in invoicing

Invoices generated straight from your sales, with nothing to retype.

/05

Payments, receivables and bank

Track what you are owed and what you owe, and reconcile bank movements without doing it by hand.

/06

Clear reports

How the business is doing at a glance: sales, expenses, margins and whatever you need, in real time.

/07

Access per person

Your team only sees what is theirs, with per-user permissions and a record of who did what.

/08

Anything else: made to measure

We adapt to your needs: we can build any custom module for your business.

How it works

From zero to your system, without the drama.

01

We learn how you work

We look at your day-to-day and what you use now, to understand what the system has to do.

02

We design it around you

We build the system around your processes, not the other way round. You see it and we adjust.

03

We migrate your data

We bring across what you already have in spreadsheets and other apps, losing nothing on the way.

04

We train you and go live

Your team learns to use it and we stay with you, adding whatever's needed.
