Custom Software Development Services
Custom software development services for growing businesses that need software built around how they work. Scoping is free, the quote is in writing before any work begins, and the code belongs to the client.
01
Who Custom Software Development Services Are For
Custom software is worth building when the alternative is bending the business to fit a tool.
Businesses that have outgrown spreadsheets.
Work that now needs several people, an audit trail and rules a spreadsheet cannot enforce.
Businesses with systems that do not connect.
Orders, enquiries or customer records typed from one system into another by hand.
Businesses with software a previous developer left behind.
An application that still runs the business, with nobody left who can change it safely.
02
The Custom Software Yeevu Builds
Four kinds of work make up most projects.
Custom Web Applications and Internal Tools
Portals, dashboards, booking systems and back-office tools built for one business. The people who will use the tool are involved from the first stage, so what is built matches how the work is actually done.
API Development and System Integrations
APIs and integrations that move data between the systems a business already uses, such as a website, a CRM, an accounts package and a payment provider, so nothing is typed twice.
E-commerce and Payment Code
Checkout, payment and order-handling code for the cases an off-the-shelf store does not cover: unusual pricing, subscriptions, or orders that have to reach another system.
Taking Over an Existing Codebase
Reading, stabilising and extending software that another developer or agency wrote, so the business can keep changing it.
03
How a Custom Software Development Project Runs
Every project follows the same five steps. Most take between three weeks and three months from start to launch.
- Free scoping — a conversation about the problem, the people who will use the software and what it has to connect to. Scoping is free.
- Written quote — the price and the pricing model, in writing, before any work begins.
- Build in stages — the software is built in stages, and each stage is shown working before the next begins.
- Launch — the software goes live with the people who will use it.
- Support — the engineers who built the software stay available to maintain and extend it.
04
Custom Software Development Pricing: Fixed Price or Time and Materials
Yeevu works on either of two pricing models. The written quote says which one applies and why.
Fixed price. For a defined scope: one price, agreed in writing before work begins.
Time and materials. For work whose scope is expected to change: the time worked is billed as the project goes.
Scoping is free under both models.
05
Who Owns the Custom Software When the Project Ends
The client does. The code written for a project belongs to the client.
