Custom software development

Turn repeated manual workinto a system you can keep using.

Booking and order handling, copying data between systems, recurring reports, or connecting Shopify to the rest of the operation. I start with the work people repeat today, then define the useful scope for a web app, internal tool, or integration.

Start with the work

You do not need a finished feature listto explain the problem.

Before deciding on an app, I map who receives the information, where they enter it, what must be checked, and who needs it next.

  1. 01

    Taking bookings and checking availability

    What happens today
    Requests arrive by form, email, or phone and are copied into a calendar by hand.
    A possible software direction
    A booking web tool that brings requests, availability, confirmations, and progress into one flow.
  2. 02

    Re-entering each order elsewhere

    What happens today
    The same order details are typed again, with extra work to find missing or duplicate entries.
    A possible software direction
    An internal tool that reshapes order data for review and moves it into the next agreed step.
  3. 03

    Combining spreadsheets for every report

    What happens today
    Files are collected and copied into the same weekly or monthly calculations.
    A possible software direction
    A shared input and reporting flow that keeps the numbers people need in one place.
  4. 04

    Shopify is separate from the surrounding work

    What happens today
    Product, order, or inventory data is moved by hand into another way of working.
    A possible software direction
    A tailored integration after checking the Shopify API, CSV, or other connection available for the job.

What I build

Choose the right shape for the work.

The starting point is the people using it, the information that must be kept, and how they recover from exceptions — rather than a large system by default.

01Web apps
Purpose-built browser screens and processing for entering, reviewing, and updating work.For example: booking, order management, approval and review flows
02Internal tools and automation
Bring spreadsheet and re-entry work into one flow that remains easy to inspect.For example: data entry, reports, documents, and notifications
03Shopify and tailored integrations
Review the APIs or CSVs available and design a safe handoff between existing services.For example: connecting product, order, or inventory data to internal work

Before building

If an existing product fits,I will show you that first.

When a Mumu Labo product fits

Check the existing product

When one of my products already covers the problem, I point you there before proposing custom work. The product page distinguishes what is live from what is still in development or preparing for launch.

When existing products do not fit

Discuss the specific workflow

I review the process, roles, stored information, and external services involved, then define the custom-development scope.

How it works

Define the scope from the real workflow.

I use your enquiry to identify the questions and assumptions needed for a quote. The final scope, price, and way of working are confirmed before work starts.

  1. 01

    Share the difficult work

    Describe the current steps, services in use, and where the work becomes difficult.

  2. 02

    Map the flow and boundaries

    Define inputs, review, storage, connected systems, and what this project should cover.

  3. 03

    Receive a project quote

    I prepare the scope and price from the required features and open questions.

  4. 04

    Design, build, and check

    Build the agreed scope and check it against the actual workflow.

Start with the work you repeat by hand.

You do not need to name the feature first. Use the English contact form to share the current steps, services in use, and the result you want.
