Development · stores, ERP, standalone modules
We write what your systems lack.
ERP covers nine processes out of ten. The tenth lives in Excel, in email and in one employee's memory. We turn it into software: inside your ERP, beside it, or as an app for the store.
We publish software ourselves.
Twelve apps in the Shopify App Store passed review and remain in the catalogue. Writing the code is half the job; the other half is updating it and answering users.
Specification first, code second.
One page for the manager, a specification for the builders, a fixed price. A demo every week on your data.
The code is yours.
The repository and the accounts are yours; we work inside them.
Three areas
Online stores.
Stores on Shopify, WooCommerce and OpenCart, apps for them, and AEO so that ChatGPT and Gemini name your product.
ERP systems.
Customisations of Dynamics 365 and 1C, reports, exchanges with the warehouse, the bank, the EDI provider and the tax gateway. So that entering an operation correctly is easier than working around it.
Standalone modules and protection.
Accounting, warehouse, document flow, when the process fits no ready-made system. And software that notices losses before the accountants do: reconciliations, access logs, alerts on suspicious orders.

How a project goes
A conversation about the task.
45 minutes. You describe the process; we say what a program can do with it and what it cannot.
Functional specification.
One page for management and a detailed specification for the builders. Scope and price are fixed here.
Development in plain view.
A weekly demo on your data.
Launch and one control figure.
Deployment, code handover and one number you read every morning.
What we do not do
We do not implement ERP from scratch and do not sell licences. We come where the system is already in place and extend it.
Where to start
Show us the Excel file your department cannot work without. That is usually where the program waiting to be written is hiding.
Questions from the first call
What does Master Development develop?
Master Development writes apps for online stores on Shopify, WooCommerce and OpenCart, customisations of Dynamics 365 and 1C, standalone accounting and warehouse modules, and software that protects a business. The studio's own apps are in the Shopify App Store.
How is the development price set?
The first conversation is 45 minutes and free. The functional specification costs a fixed sum, development runs at the fixed price from the specification, and support is billed monthly.
Who owns the code?
The client. The repository, the code and the accounts stay with the client; Master Development works inside them.
Does Master Development implement ERP from scratch?
No. Master Development extends Dynamics 365 and 1C where the system is already in place, and does not sell licences.
How does the client see progress?
A weekly demo on the client's data. Scope and price are fixed in the specification; additions are priced separately and in the open.
Show us the Excel your department cannot live without.
In 45 minutes we will say which program is hiding in it and how big the job is.
