At a glance

Custom business software replaces a critical Excel file or ill-fitting SaaS product when no standard solution can support the workflow. TMG Conseil defines the real need, designs a simple and maintainable application and connects it to your data. We build only what creates genuine leverage, never for the sake of writing code.

Key points

For whomSMEs constrained by Excel or rigid SaaS products.

WhenSpecific workflow and scattered data.

DeliverablesBusiness application and data migration.

TimelineDepends on scope.

Custom software is not always the right answer.

TMG Conseil recommends custom business software only when the operating model is specific, strategic or cannot be supported properly by a reasonable SaaS product. The work therefore begins with a simple question: should we genuinely build, or choose and configure an existing solution more effectively?

functional scoping and role mapping;
useful prototype before full development;
authentication, permissions, audit trail, exports and documentation;
possible handover to an internal team or third-party provider.

Typical cases

Critical Excel fileOne file runs an entire process and creates a risk of error.

PortalCustomers, suppliers or employees need to submit, track or approve items.

Workflow designThe stages are too specific for a generic SaaS product.

DataSeveral sources need to be consolidated into one reliable system of record.

Before building

The right tool begins with clear scoping.

Code comes after the target operating model.

Custom software or an off-the-shelf product?

Choose the market first when a product exists and supports your rules. Choose custom software when the critical workflow fits nowhere without compromise.

Is depending on custom software risky?

Not if the code and data remain yours, documented and maintainable. This requirement is set from the scoping stage.

How long does a first version take?

A focused scope can be delivered in a few weeks. We release a useful version quickly, then extend it based on real usage.
