    is our delivery cycle: every two weeks you get working software, not a percentage

    ZenSavvy, our standard

Nobody buys software because they want software.

They buy it because someone has spent months doing by hand what a computer does in one second.

How many hours a month does your team spend copying and pasting?

What is custom software? a system built around your operation, instead of forcing you to change it

  1. Today: the process lives in someone’s head

    The order arrives by text, gets written on a pad, moves to a spreadsheet and then someone types it again into the billing system. Every hop is a chance to get it wrong, and all of it depends on one person showing up. Custom software exists so that process stops being fragile.

  2. The system: entered once, in one place

    We build the application around the process you already run: the same steps, the same names, the same rules, executed by the system instead of by hand. Data is captured once and travels on its own. It can be a web app, a mobile app, or both talking to the same server.

  3. What you keep: hours back and a clear trail

    Your team stops typing and starts deciding, and you can see where anything stands without asking anyone. And the system is genuinely yours: the code, the database and the accounts are in your name, not rented from a platform that can raise its price.

The cost of not doing it

A manual process is not free. It is just a cost nobody invoices

Someone spending two hours a day moving data from one place to another burns about 500 hours a year. You are already paying for that time, it just shows up as payroll instead of as a line item for software. And unlike the system, that expense repeats every year and grows as the business grows.

We start with the scope, not with the code before a single line gets written, we put in writing what gets built

The first deliverable is not software. It is a scope document listing the modules, what each one does, the order they get built in and what each block costs. With that you decide whether you want all of it, part of it or none of it, and you know exactly what you are buying before you sign anything.

What we will tell you even when it costs us the job

If an off-the-shelf product already solves your problem for a monthly subscription, we say so and help you set it up. Custom software is worth it when your process is your competitive advantage, not when it looks like everyone else’s.

Scope document

Free credited against the project if you move forward

The modules and sprints shown are an example. Your document comes from your real operation.

How we build it four stages, and at every one you can see where you stand

  1. Week 1

    Understand the operation

    We sit with the people who do the work today, not only with the people who manage it. That is where the real process map comes from, exceptions and shortcuts included, and it almost never matches the manual.

  2. Week 2

    Scope and prototype

    You get the scope document and clickable screens. You can walk the system and ask for changes while changing is still free, before a single line of code exists.

  3. Every 2 weeks

    Build in increments

    Every two weeks we ship a working module to a staging environment you have access to. No percentage-complete reports: either the module runs or it does not.

  4. At handoff

    Delivery and handover

    You get the code, the database, the documentation and the service accounts in your name, plus training for your team. Keeping us on for maintenance is your call, not a condition.

98% of our projects ship on time, and we answer any request in under 24 hours.

Why custom instead of off-the-shelf the right question is not what it costs, but what it saves

  • It fits you

    A generic system makes you change your process to fit inside it. Custom software does the opposite: it takes your process as it is and automates it, including the exceptions no product catalog accounts for.

  • You own the code

    We hand over the repository, the database and the accounts in your name. You can continue with us, with an in-house team or with another vendor. There is no technical hostage.

  • It grows with you

    It is built in modules, so adding a new area does not mean rebuilding what is already there. And because you own the code, the cost of growing does not depend on anyone’s price list.

  • Genuinely fast

    We write lean code and treat performance as part of the deliverable. An internal system that takes five seconds to open a screen is a system your team will route around.

What we weigh when we decide how to build it our prioritization criteria, with the weight we give each one

  • It has to hit the real bottleneck

    Before any technical decision comes knowing which step stops everything today. If the system does not attack that step, it will look great and go unused.

    30%
  • Your people have to want to use it

    A system the team routes around is money burned. We design screens around the task, with as few clicks as possible and the words your company already uses.

    22%
  • Speed and uptime

    We measure response times and treat them as a requirement, not a bonus. A slow internal system gets abandoned exactly like a slow website.

    18%
  • It has to talk to what you already run

    Billing, accounting, messaging, payment gateways. Integrating what already works is cheaper than replacing it and makes adoption far less painful.

    14%
  • It has to be maintainable

    Readable, documented, tested code. The big bill on a system is not building it: it is changing it two years later, when whoever wrote it is gone.

    9%
  • Security and backups

    Role-based access, encryption in transit and automatic backups. Your operational data is the most expensive asset in the system and gets treated that way from day one.

    7%

How long does it take? A mid-sized operations system usually lands between 8 and 16 weeks, split into two-week deliveries. A simple mobile app can ship in 6. The scope document gives you the number for your project before it starts.

When it is worth it and when it is not not every business needs its own software, and saying so is part of the job

Custom software pays off when the way you operate is different from your competitors, or when your volume no longer fits in a spreadsheet. If your process is standard and low-volume, there is almost always a subscription tool that works out better.

Clearly worth it

Businesses with a process of their own, several people entering the same data, or volume that already broke the spreadsheet.

  • Distributors and wholesalers with multi-location inventory
  • Logistics and transportation companies
  • Manufacturing with production or maintenance control
  • Clinics and practices with scheduling and records
  • Professional services billing by project or by hour
  • Any business that today depends on one critical Excel file

Something else is usually better

When the process is identical to everyone else’s in the industry, a product already solves it for a fraction of the cost.

  • A one-person business with no team to coordinate
  • You only need invoicing or bookkeeping
  • You only need appointment scheduling
  • You only need to sell standard products online
  • Low, stable volume with no growth on the horizon

If your case sits on the right, we tell you and help you pick the tool that actually fits. We would rather not sell you a project than sell you one you were never going to use.

Pricing

What an application costs a clear floor, and why

There are no tiers because no two systems are alike. There is a floor, and the detail of what it is based on.

From $4,650 USD

six weeks of dedicated development, the minimum for a project

Month of dedicated development
$3,100 USD
Project minimum, six weeks
$4,650 USD

What the cost is based on

The cost is the time of a team working only on your project, plus the infrastructure and tooling that work requires. A month of dedicated development costs $3,100 USD. The minimum phases of a project add up to six weeks, and that is where the $4,650 USD starting point comes from. What raises the number is the number of modules and how tangled the process being automated is.

Before we start

  • Definition of the business and its services, same as on a website
  • Definition of scope in writing, which is what sets the price

The phases, once we start

  1. Requirements and open questions Subject to a meeting with you. 2 days
  2. Wireframes Subject to a meeting with you. 3 days
  3. Client review and adjustments 1 week
  4. UI and UX development Defined by the scope. Minimum 1 week
  5. Backend development Defined by the scope. Minimum 1 week
  6. Testing and quality control 1 week
  7. Final review with you 1 week

Six weeks is the floor, not the average. A mid sized operations system usually lands between 8 and 16 weeks.

FAQ

What people always ask us

How much does custom software development cost?

It depends on the number of modules and how tangled the process is, not on the size of the company. A mid-sized operations system usually falls between 8 and 16 weeks of work, and a simple mobile app can land in 6. At ZenSavvy the price is set in the scope document, in writing and broken into blocks, so you can see exactly what you are paying for and remove anything you do not need.

How long does a custom software project take?

We work in two-week deliveries: every fortnight there is a working module in a staging environment you can access. A mid-sized operations system usually lands between 8 and 16 weeks. We never report progress as a percentage, because 70% of a system cannot be used.

Do I own the code?

Yes. At handoff we transfer the repository, the database, the documentation and the service accounts into your name. You can continue with us, with an in-house team or with another vendor without asking our permission or paying a ransom.

Do you build mobile apps as well as web systems?

Yes. We build mobile apps for Android and iOS, and most often the app and the web system share the same server and the same database, so what a driver enters in the field shows up instantly on the office dashboard.

Can it connect to the systems we already use?

Yes, and it usually should. We integrate with billing, accounting, messaging, payment gateways and anything that exposes an API. Integrating what already works is cheaper than replacing it and gets your team onto the new system far faster.

What happens if the project grows halfway through?

The scope is written and split into blocks, so a new module is quoted as a new block instead of renegotiating the whole project. That is the reason to build in modules: adding an area does not force a rebuild of what came before.

Do you maintain the software after delivery?

Yes, and it is deliberately optional. We offer maintenance, support and ongoing development if you want it, but because the code and the accounts are in your name you are never obliged to stay with us for your system to keep running.

Do you work with clients across the United States?

Yes. The entire process is remote and works the same wherever your business is. Discovery sessions, fortnightly reviews and training happen over video, and the staging environment is online so you can open it whenever you want.
