Questions, answered.
The things people usually ask before starting a project with us. Don't see yours? Ask us directly.
What does Williams Systems LLC do?
Williams Systems LLC is a full-service software company. We design and build websites, web applications, SaaS platforms, and mobile apps, and we set up and run the cloud infrastructure behind them. One team handles design, front end, back end, and hosting, so nothing gets lost between vendors.
How much does a website or app cost?
It depends on the job. Every project starts with a free discovery call, and afterwards you get a written scope with the timeline and the price before any work begins. Some jobs are a one-time price, others suit a monthly plan; we agree which before we start, so there are no surprises.
How long does a project take?
It depends on the size of the project. The timeline is written into your scope before any work begins, we move fast, and you get progress updates while it’s being built.
Do I own the code and the accounts?
It depends on the plan. On a one-time project, the code, the domain, and the accounts are yours. On a monthly plan, we host and manage it for you. Either way, it’s written into your scope before we start.
What technologies do you use?
Mostly React, Next.js, and JavaScript on the front end, Node.js and Python on the back end, and Supabase and PostgreSQL for data and sign-in. We pick what fits your project.
Can you work on an existing website or app?
Yes. We can review an existing codebase, fix problems, add features, and improve performance and security, as well as build new products from scratch.
Do you offer support after launch?
Yes, two ways: a monthly support plan that covers fixes, updates, and new features, or pay per job whenever you need something. Monthly plans have a 3-month minimum, then continue month to month.
Where are you based, and who do you work with?
We work remotely with businesses anywhere in the world.
Who will I talk to?
You talk directly to Landon Williams, the founder, who is the person building your project.
Do you require a deposit?
Payment terms, including any deposit, are written into your scope before work begins.
How many revisions do I get?
We revise the design with you until it’s right, within the agreed scope.
How do I get started?
Schedule a free discovery call or email us about your project. We will ask about your goals and users, then send back a scope, timeline, and price.
