01 — Custom software & CRMs

Software built around your business, not the reverse.

Off-the-shelf tools force you to bend your process to their screens. I design and build the system your team actually needs: your pipeline, your jobs, your invoices, your reporting — in one place, with the automations that remove the repetitive work.

The short answer

Agency Zero builds custom software, CRMs and business apps for small businesses in York, PA and across Pennsylvania. Luke Knight designs and builds each system himself, so you deal with one person from first call to launch.

How it works

  1. 01

    Map the workflow

    I sit with how work really moves through your business and find the friction.

  2. 02

    Design the system

    Screens, data and automations designed together and agreed before building.

  3. 03

    Build in slices

    Working software every few weeks, so you use it and shape it as it grows.

  4. 04

    Launch & support

    Migration, training and ongoing improvement as the business changes.

Questions

Often you should. Off-the-shelf tools are cheaper and faster when your process is ordinary. Custom software starts to make sense when your process is genuinely different, when you are stitching several tools together with spreadsheets, or when the cost of bending your work to someone else's screens keeps growing. I will tell you honestly which side of that line you are on after a short discovery conversation.

  • Good reasons to go custom: unusual workflow, several tools that do not talk to each other, or a CRM your team avoids using
  • Good reasons not to: a standard sales pipeline and a team happy with a mainstream tool

Ownership and hand-over are agreed in writing before work starts. The aim is that you are never locked in to me: the code is documented, the data stays in an account you control, and another developer could pick it up. If you want me to host and maintain it, that is a separate, clearly priced option rather than a hidden dependency.

A focused first version, such as one pipeline, the key screens and the main automations, can be usable in a few weeks. Larger systems are delivered in stages so value arrives early and you can change direction as you learn. I give a fixed scope and price for each stage after discovery, so you know what you are paying for before anything is built.

Usually yes. Common connections include accounting, email, calendars, payments such as Stripe, forms and spreadsheets. I list every integration during discovery and flag any that depend on a third party's limits, so there are no surprises midway through.

  • Typical examples: Stripe, Google Workspace, accounting software, email and SMS, website forms

That is the point of building it around you. Because the system is yours, stages, fields and automations can be adjusted without waiting for a vendor roadmap. Small changes after launch are quick, and larger ones are scoped like any other stage.

Access is limited to the people you choose, data is stored in a private database, and backups are part of the setup. I design permissions from the first release rather than adding them later, and I will explain plainly where your data lives and who can see it.

Agency Zero does. Luke Knight designs and builds custom software, CRMs and internal tools for small businesses in York, PA and across Pennsylvania, working directly with the owner rather than through a sales team. Meetings can be on a video call, or in person around York where that helps.

Yes. Contractors, trades and local service businesses are a good fit because their work is repeatable but rarely matches off-the-shelf software: quotes, jobs, schedules, follow-ups and invoices. A first version covering one workflow can usually be live in a few weeks, then grows in stages.

It depends on scope, so I price it after a short discovery call. Each stage has a fixed scope and price agreed before building starts, which means you know the cost of a stage before it begins. A small, focused first version costs far less than a full system, and you decide how far to go.
