Custom Software & App Development
Off-the-shelf software fits most of what a business does and none of what makes it different. Allwyn Mac Services builds custom software, web and mobile applications and integrations for companies across the Philadelphia region: the quoting tool, portal, dashboard or automation that your industry's software does not offer, built to fit how you actually work and supported after launch.
Custom software
Internal tools, dashboards and line-of-business applications designed around your process, replacing the spreadsheets and manual steps that everyone works around.
App development
Web and mobile apps for customers and staff — booking, ordering, field service, customer portals — built for iPhone, Android and the browser from one codebase.
Integrations & automation
Systems connected so data is entered once: accounting, CRM, e-commerce, scheduling, email and the APIs of the tools you already pay for. Repetitive work automated.
Application maintenance & support
Existing applications kept running, secured and updated — including software built by someone no longer around. Bug fixes, hosting, monitoring and improvements on a monthly plan.

Frequently Asked Questions
How much does custom software cost?
It depends entirely on scope, so we start with a short discovery session and give you a fixed quote in phases, so you can start small.
Can you take over an app someone else built?
Yes. We review the code, secure and stabilise it, document it and then improve it. This is a large part of our maintenance work.
Do you build mobile apps for both iPhone and Android?
Yes, usually from one codebase so both stay in step and cost less to maintain.
Will we be locked in?
No. You own the code and the accounts, and everything is documented so another developer could pick it up.
