Frequently Asked Questions

01.01

What is a fixed price and scope development model?

A fixed price and scope model is a software contract where the exact project features, total budget, and delivery timelines are finalized and locked in before any coding begins. It is a highly secure approach for businesses that want a guaranteed launch date with absolutely zero budget increases.

02.02

What if my project scope isn't fully defined yet?

That is completely fine. If you only have a rough idea or a high-level feature list, we start with our Product Discovery Call. Our senior software architects will work with you to map out your user journeys, write your technical specifications, and build a detailed product backlog. Once that blueprint is complete, we can lock in a secure firm fixed price to build your software.

03.03

Is a fixed price agreement right for my software project?

This model is perfect if you have a well-defined project scope, clear software feature requirements, and an established budget. It works exceptionally well for building Minimum Viable Products (MVPs), straightforward business applications and software migrations where the end goals are firmly set from day one.

04.04

What happens if I want to change or add features mid-project?

If you need to adjust your requirements during development, we use a clear and simple change-management process. We look over your new feature request, calculate its impact on the timeline and budget, and present a separate mini-quote so your main development pipeline keeps moving forward smoothly.

05.05

How do you estimate the fixed cost of a software project?

We analyze your technical requirements during our initial discovery workshops. Our senior software architects break down the application architecture, coding hours, design assets, and QA workflows required. We then provide a transparent total cost estimate backed by a clear breakdown of each phase.

06.06

Who manages the daily development workflow in a fixed price project?

InvoZone handles 100% of the internal project management. We assign a dedicated Scrum Project Manager to your project who tracks daily developer tasks, coordinates sprint reviews, and handles resource planning, meaning your leadership team stays completely free from daily micromanagement.

07.07

How are payments structured in a fixed price contract?

Payments are tied directly to clear, measurable project milestones rather than hourly bills. You pay a standard initial deposit to kick off the architecture phase, and the remaining balances are split and released only after you review and approve specific working deliverables at each phase.

08.08

What happens if the project takes longer than expected to complete?

Because the contract is fixed-scope and fixed-price, InvoZone absorbs all internal financial risks. If our engineering team runs into unexpected software development blockages that cause internal delays, your final price stays exactly the same. You never pay extra for timeline overruns.

09.09

Who retains the intellectual property rights for the completed code?

Yes. We offer both DeFi app development and cryptocurrency wallet development. We routinely build tools for decentralized lending platforms, token staking setups, crypto payment gateways, and custom digital wallets that feature multi-chain support, easy asset management, and safe recovery options.

1010

Can you modernize an old legacy application under a fixed price model?

Yes. We build private and permissioned blockchain networks for companies that need total data privacy and controlled user access. This is highly useful for corporate supply chains, internal business records, and secure data sharing where only approved employees or partners are allowed to view sensitive information.
