How much does custom Magento extension development cost?

Pricing is a fixed written quote for your scope. Send the details on WhatsApp and I reply within one working day.

Three fixed-price tiers, no per-hour surprises:

• Spec Audit: 1-2 days, just the spec, you can take it to any developer
• Standard Extension: -3-6 weeks, single-purpose extension with Hyvä + Luma support, MFTF tests, docs, GitHub repo
• Marketplace-Ready: -6-10 weeks, includes Adobe Marketplace submission package, EQP compliance, listing copy, screenshots, demo video, customer-support runbook

If your extension is unusually complex (multi-store ERP integration, custom payment gateway, headless GraphQL surface), we’ll quote per spec. No surprise invoices.
