Infinity Systems vs a software agency, compared by criterion
Criterion	A software agency	Infinity Systems
Price model	Hourly, $50 to $150, teams of 2 to 10	Fixed price, $10,000 to $100,000
Date	An estimate, revised as work goes on	On the quote
Who you talk to	An account or project manager	The founder, who designs and reviews the code
Who writes the code	A team that can change during the project	AI coding agents, with every change reviewed by the founder
Discovery	Often a paid phase of several weeks	A 30-minute call and a one-page brief; five days for platforms
Ownership	Often transferred at final payment	Repository and accounts in your name from day one
Leaving early	Notice period and a handover project	After week one, pay the deposit and keep everything
Capacity	Many people at once	At most three engagements at once

Choose us when

You need a price and a date in writing before you commit.
The build fits in 2 to 12 weeks and $10,000 to $100,000.
You want the person on the call to be the person reviewing the code.

Choose someone else when

You need many people working in parallel for a year or more.
You need on-site staff, or a vendor with a large bench for many projects at once.

What each one sells

An agency sells capacity: a team, a project manager and a method, billed by the hour. You buy time and hope the time adds up to the outcome. We sell the outcome. The scope, the price and the date are written down before work starts, and the work is done by AI coding agents under the review of one senior engineer.

Where the difference shows

It shows in the quote. An agency quote is a rate times an estimate, and the total is known at the end. Ours is one number. It shows again in who you talk to: in an agency you rarely talk to the people writing the code; with us you talk to the person who reviews every change.

Agency rates are from the Clutch software development pricing guide, 2026.

When not to pick us

If your programme needs many people for a long time, an agency is the right shape. If you cannot write the scope down yet, buy a few hours of advisory first, ours or anyone’s.

Follow-up questions.

Why is a fixed price safer than an agency estimate?

Because the builder carries the estimation risk. If an hourly project takes longer, you pay for the extra hours. If our fixed-price build takes longer, we absorb it. Scope you add later is quoted separately, in writing.

Can a small team handle a platform-sized build?

Up to 8 to 12 weeks and $100,000, yes. That is the Platform Sprint. Contractors join on demand for specialist work. Beyond that size, an agency or an in-house team is the better shape, and we say so on the first call.
