The things people most often ask before starting an app or plugin project. Can't find your answer? Ask us directly.
demfilz is a software studio that builds three things: custom applications (web and SaaS), WordPress and WooCommerce plugins, and Shopify apps. We focus on these areas so the code we ship meets each platform's standards and is genuinely maintainable.
Yes. We build custom WordPress and WooCommerce plugins from scratch, add features to existing plugins, and fix or harden ones that are misbehaving. Everything is written to the WordPress Coding Standards and can be prepared for the WordPress.org plugin directory.
Yes. We build custom and public Shopify apps, checkout and theme app extensions, and integrations between Shopify and other systems. Apps are built to Shopify's requirements so they can pass app review.
Yes. Alongside plugins we build complete web and SaaS applications, dashboards, APIs and automations. If you are not sure whether your idea is best as a plugin, an app or a standalone product, we will help you decide.
Yes, completely. Every project is handed over with full source code, and intellectual property is transferred to you on final payment. There is no proprietary lock-in and no requirement to stay on a retainer to keep your software working.
It depends on scope, but most plugin and small-app projects fall between roughly AUD $1,000 and $15,000, and larger products go beyond that. We quote a fixed price up front after a short scoping conversation, so there are no surprise hourly bills.
A focused plugin or Shopify app is often a few weeks; larger applications take longer. After scoping we give you a realistic timeline and build in visible increments so you can see progress along the way.
Yes. We prepare submissions to meet the platform's guidelines. For WordPress that includes running the Plugin Check tool and fixing what it flags; for Shopify it means meeting the app review requirements. We then guide the listing through approval.
Yes, but it is optional. Because you own the code, you are free to maintain it yourself or use any developer. If you would rather we handle updates, compatibility and small changes, we offer support on a simple, no-lock-in basis.
demfilz is based in Australia and works with clients worldwide. We work asynchronously by default and are comfortable across timezones, so location is rarely an issue.
Yes. We ship clear setup documentation with every plugin and app we build. For example, our Demfilz Shipping Rates for Australia Post plugin has a full step-by-step setup guide covering installation, API credentials, services and troubleshooting.
Send the details through the Request an app form, or use the contact form. We will reply with a few questions, then a plan, timeline and fixed quote. If it is a fit, we begin; if not, you have lost nothing.
