Magento Extensions

When the off-the-shelf module almost-but-not-quite does it, we build the one that does.

The Magento Marketplace is full of modules. For 80% of what most stores need, you can find an off-the-shelf extension that does the job. For the other 20% — the bits that make your business actually different — you usually end up either compromising your process to fit the module, or chaining three modules together and praying nothing breaks.

We build the custom modules that solve the 20%. Cleanly, upgrade-safely, and following Adobe’s coding standards so any competent Magento dev can pick them up later.

Custom modules we’ve built

  • Quote workflows — for B2B stores where customers add to cart then request a formal quote, often with rep approval and custom pricing rules.
  • Custom shipping calculators — bespoke courier logic that the standard carriers and marketplace modules can’t cover (e.g. dimensional weight calculations, multi-warehouse routing, hazmat surcharges).
  • Rep allocation — automatically assigning customers to internal sales reps based on territory, account size or product mix.
  • Repeat order & subscription — for stores selling consumables where customers want a one-click reorder of their last basket.
  • Punchout integrations — for B2B selling into corporate procurement systems (Coupa, Ariba, Oracle).
  • Bespoke loyalty & rewards — point systems, tiered benefits, referral mechanics built around your customer model rather than a generic plug-in.

How we build them

Every module is built as a self-contained Magento composer package, follows Adobe’s module standards, and ships with documentation. We use dependency injection, event observers and plugins rather than rewriting core files — so updating Magento doesn’t break our work.

Where there’s admin functionality, we build proper admin UIs using Magento’s native UI components (grids, forms, system config) — not janky standalone admin pages.
