B2B platforms and marketplaces

Software for the work between businesses.

We help B2B teams build and improve catalogs, company accounts, document sharing and buyer/supplier workflows. Bring an existing platform or one operational flow that needs to work better.

Where we help

Connect the catalog, accounts and daily operations.

Help buyers and suppliers manage products, share documents and keep conversations connected to their business accounts. We build the application features and scheduled tasks behind that work.

01

Catalogs and imports

Build product records and import handling with validation that explains which rows need correction.

02

Organization workflows

Define company accounts, access and the records each user can work with.

03

Conversations and documents

Connect buyer/supplier conversations, shared documents and the context needed for follow-up.

04

Background operations

Handle reminders, scheduled notifications and reporting outside the immediate user interaction.

A practical starting point

Start with a catalog import, account feature or reminder.

We can improve one task first, including its screens, data checks and scheduled actions, before taking on a wider part of the platform.

Why Stax3

Data validation experience

Our import work handles inconsistent input and reports specific problems before records are accepted.

Connected backend work

We work across application records, APIs and background jobs, including checks that a scheduled action is still relevant.

Engineering decisions

Build around one business task.

01

Review the flow

Map the organizations, records and handoffs involved in one business task.

02

Implement the first improvement

Build the interface, validation and backend behavior needed for that task.

03

Check and hand over

Test expected and invalid inputs, review permissions and document background behavior and release steps.

Relevant experience

Marketplace engineering in practice.

Our marketplace work includes CSV normalization, row-specific errors, organization accounts, document sharing and messaging. Elixir/Phoenix LiveView, PostgreSQL and Oban supported the connected application and background jobs.

Useful answers

Before we start.

Can you improve an existing platform?

Yes. We review the code, data and priorities, then agree on a focused feature or continued engineering scope.

Do we need a complete rebuild?

We first assess whether the existing application can support the requested change. The scope follows the code and business task.

Start with the context

Which business workflow needs attention?

Share the platform, the users and what happens today. We will discuss a useful first change.
