Why doesn't any software company give a single price for custom systems?

Because a system's cost doesn't come from what type of system it is. It comes from dozens of independent variables. The software engineering reference model, COCOMO II, developed by Barry Boehm at the Center for Software Engineering of the University of Southern California, defines 17 effort multipliers and 5 scale factors grouped into four categories: product, platform, personnel, and project. One example of the scale involved: requiring high reliability adds 10% to the estimated effort, and very high reliability adds 26%—a quarter of the project for a single variable. On top of that, functional size scales exponentially, not linearly: doubling the scope raises the cost by more than double, because coordination, testing, and interdependencies all grow with it. When someone tells you a given type of system costs X, they're leaving out the 17 variables that set the real price of yours.

What factors make custom software more or less expensive?

Four main factors explain the biggest differences between two quotes. First: contractual scope—does the vendor only code and test, or also gather requirements, manage the project, and deploy to production? Second: product requirements—how much documentation and what artifacts must be delivered beyond working software. Third: required technology—programming languages, frameworks, and tools. Fourth: management model—dedicated team versus on-demand factory. This classification comes from Brazilian consulting firm FATTO's analysis of 57 federal-agency bids awarded between 2014 and 2017, combined with Gartner IT Key Metrics data: price per function point ranged from US$255 to US$1,000, averaging US$488, while Gartner placed the range at US$200 to US$600. The same unit of functionality, measured by the same standard, with prices that vary by nearly 4x. This is public-sector data from Brazil from several years ago, so it's not directly transferable as a Paraguay figure, but the structural finding is universal: delivering identical functionality requires different cost levels depending on what the contract covers.

Is it cheaper to buy off-the-shelf software than develop custom?

Data from the most-studied case of enterprise off-the-shelf software, ERP implementation, doesn't support that notion. According to the 2025 ERP Report from Panorama Consulting, the average cost of an ERP implementation is US$450,000 and the average project duration is 9 months, down from 15 months in the prior report. Over half of companies exceed their budget, and the reasons they cite are identical to custom development: underestimating project staffing (38%), scope expansion beyond initial specification (35%), and technical or data issues (34%). Panorama has published this report for over fifteen years and doesn't sell any particular ERP, which reduces—though doesn't eliminate—conflicts of interest. The honest conclusion isn't that custom is cheaper. It's that the costs sit closer together than people assume, and that the real comparison isn't price against price but who keeps the competitive advantage and control of the system once the project ends.

What questions should I ask when requesting custom software quotes?

Six questions separate a useful quote from just a number. First: What activities does the price include—requirements gathering, design, development, testing, data migration, production deployment, training? This is the number-one factor in price variation. Second: What integrations are included? Each connection to an existing system, whether billing, accounting, or payment processing, is additional scope and should be itemized. Third: What level of reliability and security is assumed? COCOMO II is clear that this requirement alone can add a quarter of the effort. Fourth: How is maintenance handled after delivery? It's the majority of lifecycle cost; if it's not quoted, it's not solved. Fifth: What assumptions is the quote built on, and what happens if they change? A quote with no declared assumptions has nothing underneath it. Sixth: Who owns the code and data at the end? It doesn't change the price today, but it determines what you're actually buying.

Can I use LATAM's hourly rate as a pricing reference for Paraguay?

It serves as an order of magnitude, not as a Paraguay price. The only source with declared methodology is Accelerance's annual guide, a US outsourcing consultancy: their 2026 guide places LATAM hourly rates at US$33-45 for junior profiles and US$60-75 for seniors; the 2025 guide gave a general range of US$23-90 per hour, with mid-level profiles at US$50-60. The 2026 guide is based on a survey of 60 software development partners worldwide, and the 2025 guide on data from over 100 firms. Three warnings come with the number: it's aggregated LATAM and none of these sources break out Paraguay; Accelerance isn't a neutral source, since it makes money connecting buyers with outsourcing vendors; and LATAM rates fell 7.1% year-over-year in 2025, the steepest decline among surveyed regions, so rate data ages quickly. Olivier Poulard of Accelerance himself warns that hourly rates are a poor measure of real software development cost: a team at US$40 per hour needing three times the hours is more expensive than one at US$70.

How Much Does Custom Software Development Cost in Paraguay

August 13, 2026

SummaryNo public source publishes custom software development rates in Paraguay—not CISOFT, not MITIC, not the Ministry of Industry and Commerce. A project's price depends on four variables: the functional size of the system, technical requirements, what activities the contract includes, and maintenance costs, which according to IEEE account for 60-80% of the total software lifecycle cost.

If you searched “how much does custom software development cost in Paraguay” and found an article giving you a price range in guaraníes or dollars, that number didn’t come from anywhere verifiable. There is no published market price for custom software in Paraguay; what exists instead is a set of measurable variables that determine each specific project’s cost.

Before writing this, we looked for the information in sources that should have it. The Paraguayan Chamber of the Software Industry (CISOFT) doesn’t publish rates or sector figures. MITIC doesn’t. The Ministry of Industry and Commerce doesn’t. The only public and auditable source of software prices actually paid in Paraguay is competitive bidding from the Public Contracting Directorate, but unit prices are inside the bid documents, not in an aggregated report you can cite as “market price.”

So: there is no market price for custom software in Paraguay. What does exist is a set of measurable variables that determine how much your specific project will cost. They follow.

Why Is There No Single Price for Custom Software?

Four decades of software engineering research have landed on a conclusion that frustrates anyone looking for a quick number: a system’s cost isn’t a function of “what type of system it is,” but of dozens of independent variables.

The reference model is COCOMO II, developed by Barry Boehm at the Center for Software Engineering of the University of Southern California. It has public documentation and decades of validation behind it. No one invented it to sell hours. COCOMO II defines 17 effort multipliers (cost drivers) and 5 scale factors, grouped into four categories:

Product — how reliable, complex, and documented the software needs to be.
Platform — constraints of the infrastructure where it will run.
Personnel — the team’s experience and capability.
Project — tools, team distribution, schedule pressure.

To put that in perspective: if your system requires high reliability, that alone adds 10% to the estimated effort. If it requires very high reliability—think of a system where a failure means losing money or critical data—it adds 26%. A quarter of the project from a single variable, before writing one line of code.

And functional size scales exponentially, not linearly. Doubling the scope doesn’t double the cost; it raises it by more than that, because coordination, testing, and interdependencies all grow with it.

That’s why, when someone tells you “a billing system costs X,” they’re leaving out the 17 variables that set the real price of your billing system.

Why Do Two Quotes for the Same System Show Different Prices?

Brazilian consulting firm FATTO, specialized in software metrics, analyzed 57 federal-agency bids awarded between 2014 and 2017 and cross-referenced them with Gartner IT Key Metrics data. The price per function point (a standardized unit of functional size) ranged from US$255 to US$1,000, averaging US$488. Gartner, meanwhile, placed the range at US$200 to US$600, averaging US$476. This is the single biggest reason two quotes for the same system come out different, and it’s almost never discussed.

Same unit of functionality, same measurement standard, prices that vary by nearly 4x. The analysis attributes this variation to:

Contractual scope — does the vendor only code and test, or also gather requirements, manage the project, and deploy to production?
Product requirements — how much documentation and what artifacts must be delivered beyond working software.
Technology — required programming languages, frameworks, and tools.
Management model — dedicated team versus on-demand factory.

This data is from Brazil, the public sector, and from several years ago, so it’s not directly transferable as a figure for Paraguay today. But the structural finding is universal: delivering identical functionality requires different cost levels depending on what the contract covers. When comparing two quotes, start there. The total comes after.

The same applies here: MITIC publishes a Software Standard that defines requirements for Paraguay’s state systems. Every vendor working in the public sector must meet it. That level of documentation and technical rigor is a real cost driver, not an arbitrary preference.

Where the Cost of Custom Software Development in Paraguay Comes From

The main input for custom software is skilled people’s time. On top of a developer’s salary you stack payroll taxes, bonuses, infrastructure, licenses, project management, warranty, and profit margin. On the first component, there is actual Paraguay data with backing.

The Cost of Skilled People’s Time

WageIndicator is a Dutch foundation historically linked to the University of Amsterdam, surveying salaries in 208 countries with public methodology. According to their survey, net monthly salary for a software developer in Paraguay in 2026 ranges from Gs. 4,550,772 to Gs. 13,352,006. Starting in the role, between Gs. 4,550,772 and Gs. 8,676,970. With five years’ experience, between Gs. 6,138,690 and Gs. 12,468,233, with a 48-hour weekly schedule.

Essential clarification: that’s an employee salary, not a software company’s selling rate, and it’s not “the software cost.” Between that salary and the price of a project sit payroll taxes (16.5% employer IPS contribution plus 9% employee), bonuses, infrastructure, licenses, project management, warranty, and profit margin. Presenting a salary as if it were the cost of a project would be flatly misleading. We include it for what it is: evidence that pricing builds upward from people’s time, and that a project needing senior people costs more, structurally.

As context, the legally mandated minimum wage effective July 1, 2026, is Gs. 3,044,000 monthly, following the 5% adjustment from Decree No. 6,225 of June 17, 2026, implemented by MTESS Resolution No. 670/2026. A developer sits well above that floor.

Skilled people’s time is the input. Everything else stacks on top.

Two things are also moving local prices.

A Small Local Market

Paraguay’s outsourced services market is small. According to IDB and Frost & Sullivan data cited by ABC Color, it moves about US$39.5-40 million annually and grows 15-18% per year. The breakdown: BPO and contact centers 48.65%, ITO and software 21.62%, KPO 18.92%. For perspective: Uruguay exported US$3.016 billion in global services in 2023. A small market means few vendors operating at real scale, and that shows up in team availability more than in rates.

The Maquila Regime Now Includes Services

Law No. 7547/25 of the Maquila Regime, effective September 9, 2025, and implemented by Decree No. 5714/2026, for the first time incorporated the services sector (explicitly software development, BPO, and cross-border consulting) as a beneficiary of the regime, with access to VAT credit refunds. The Ministry of Industry and Commerce notes that the services sector in maquila generated 4,000 jobs in 2024. The medium-term effect is more international demand competing for the same local talent.

The Regional Reference: Useful, But Not a Paraguay Price

If you want an order of magnitude, the only source with declared methodology is Accelerance’s annual guide, a US outsourcing consultancy publishing its survey for over a decade.

In its 2026 guide, Accelerance places LATAM hourly rates at US$33-45 for junior profiles and US$60-75 for seniors. Its 2025 guide gave a general range of US$23-90 per hour, with mid-level profiles at US$50-60. The 2026 guide is based on a survey of 60 software development partners worldwide; the 2025 guide on data from over 100 firms.

Before using that number, three things:

It’s aggregated LATAM. None of these sources breaks out Paraguay. It’s not a Paraguay market price or our quote.
Accelerance isn’t a neutral source: it makes money connecting buyers with outsourcing vendors. It’s the best available source with declared methodology, not an independent one.
LATAM rates fell 7.1% year-over-year in 2025, the steepest decline among surveyed regions, driven by competition, automation, and a developer pool that AI has helped expand. Rate data ages quickly.

Olivier Poulard of Accelerance himself warns: “hourly rates are a poor measure of real software development cost.” His argument is that project maturity, AI integration, and delivery processes weigh more on final cost than nominal rates. A team at US$40 per hour needing three times the hours is more expensive than one at US$70.

How Much Does It Cost to Maintain Software After Development?

According to the IEEE Computer Society, maintenance accounts for 60-80% of a software’s total lifecycle cost. Boehm documented in 1981 a typical distribution of roughly 30% development and 70% maintenance. It’s the most important part of the budget and the least discussed.

And “maintenance” doesn’t mean fixing bugs. The foundational Lientz and Swanson study (UCLA) of 487 companies found that roughly 60% of maintenance effort is perfective (improvements, better documentation, more efficient code), and three-quarters of total maintenance is perfective or adaptive. That is: not fixing, but evolving the system as the business changes.

The practical consequence is direct: asking “how much does it cost to develop” is asking about 20-40% of real cost. A quote that says nothing about maintenance, evolution, and ongoing support isn’t leaving out a detail. It’s leaving out most of the cost. So when you ask for a quote, ask directly about the post-delivery maintenance model. If the vendor has no clear answer, that tells you plenty on its own.

“Buying off-the-shelf is cheaper” — the Numbers Say Otherwise

US$450,000 and 9 months: that’s the average cost and duration of an ERP implementation according to Panorama Consulting’s annual report (2025 edition), the most-studied case of enterprise off-the-shelf software. The usual counterargument, that buying ready-made is cheaper, finds no support there.

That’s down from 15 months in the prior report. And over half of companies exceed their budget. Reasons they cite:

Underestimating project staffing: 38%
Initial scope expansion: 35%
Technical or data issues: 34%

These are exactly the same cost-overrun causes you see in custom development. Panorama has published this report for over fifteen years and doesn’t sell any particular ERP, which reduces—without eliminating—the conflict of interest.

None of this means custom is cheaper. The costs sit closer together than people assume, and the comparison worth making is a different one: who keeps the competitive advantage and control of the system once the project ends.

Why Distrust a Fixed Price Without Prior Assessment?

Bent Flyvbjerg from the Saïd Business School at Oxford University and Alexander Budzier studied 1,471 IT projects. Average cost overrun was 27%. But the average hides what matters: one in six projects turned out to be what the authors call a “black swan,” with average overruns of 200% and schedule slippage of nearly 70%.

The work was published in Harvard Business Review and academic journals with large declared samples—far more solid than figures circulating in industry blogs.

Translated to your situation as a buyer: a vendor who hands you a fixed number without assessing your operations is gambling. There are only two ways that bet works in their favor: they’ve inflated the price enough to absorb the error, or they’ll later cut scope to hit the number. Neither benefits you.

A serious quote starts from a needs assessment, declares its assumptions, defines what is in and out of scope, and includes an explicit contingency. There is no other honest way to put a price on something that doesn’t exist yet.

What to Ask When Requesting Custom Software Quotes

If you’re evaluating vendors, these questions separate a useful quote from just a number:

What activities does the price include? Requirements gathering, design, development, testing, data migration, production deployment, training? This is the number-one factor in price variation.
What integrations are covered? Each connection to an existing system (billing, accounting, payment processing) is additional scope and should be itemized.
What level of reliability and security is assumed? COCOMO II is clear: this requirement alone can add a quarter of the effort.
How is maintenance handled after delivery? It’s the majority of lifecycle cost. If it’s not quoted, it’s not solved.
What assumptions is the quote built on, and what happens if they change? A quote with no declared assumptions has nothing underneath it.
Who owns the code and data at the end? It doesn’t change the price today, but it determines what you’re actually buying.

A Real Number Only Comes from Your Specific Case

How much does custom software development cost in Paraguay? There’s no public figure answering that: no official Paraguayan source publishes sector prices. What can be worked out is the cost of a specific project, based on its functional size, integrations, reliability requirements, contract scope, and maintenance horizon, which accounts for 60-80% of total cost.

So the honest answer is that the question has no public answer. Your project does.

At Flexora we assess that before giving a number, precisely for the reasons we laid out above. If you’re pricing out a custom system, take a look at how we approach custom software development and request a quote built on your actual operations, with the scope documented and the assumptions spelled out.

Frequently asked questions

How much does custom software development cost in Paraguay?: There is no published market price for custom software development in Paraguay. We checked the sources that should have it: the Paraguayan Chamber of the Software Industry (CISOFT) doesn't publish rates or sector figures, MITIC doesn't, and the Ministry of Industry and Commerce doesn't either. The only public and auditable source of actual software prices paid in the country is competitive bidding from the Public Contracting Directorate, but unit prices are embedded in bidding documents, not in an aggregated report citable as a market price. Any closed price range in guaraníes or dollars you find published didn't come from a verifiable source. What can be worked out is the cost of your specific project, based on its functional size, integrations, technical requirements, and how far it needs to evolve.
Why doesn't any software company give a single price for custom systems?: Because a system's cost doesn't come from what type of system it is. It comes from dozens of independent variables. The software engineering reference model, COCOMO II, developed by Barry Boehm at the Center for Software Engineering of the University of Southern California, defines 17 effort multipliers and 5 scale factors grouped into four categories: product, platform, personnel, and project. One example of the scale involved: requiring high reliability adds 10% to the estimated effort, and very high reliability adds 26%—a quarter of the project for a single variable. On top of that, functional size scales exponentially, not linearly: doubling the scope raises the cost by more than double, because coordination, testing, and interdependencies all grow with it. When someone tells you a given type of system costs X, they're leaving out the 17 variables that set the real price of yours.
What factors make custom software more or less expensive?: Four main factors explain the biggest differences between two quotes. First: contractual scope—does the vendor only code and test, or also gather requirements, manage the project, and deploy to production? Second: product requirements—how much documentation and what artifacts must be delivered beyond working software. Third: required technology—programming languages, frameworks, and tools. Fourth: management model—dedicated team versus on-demand factory. This classification comes from Brazilian consulting firm FATTO's analysis of 57 federal-agency bids awarded between 2014 and 2017, combined with Gartner IT Key Metrics data: price per function point ranged from US$255 to US$1,000, averaging US$488, while Gartner placed the range at US$200 to US$600. The same unit of functionality, measured by the same standard, with prices that vary by nearly 4x. This is public-sector data from Brazil from several years ago, so it's not directly transferable as a Paraguay figure, but the structural finding is universal: delivering identical functionality requires different cost levels depending on what the contract covers.
Is it cheaper to buy off-the-shelf software than develop custom?: Data from the most-studied case of enterprise off-the-shelf software, ERP implementation, doesn't support that notion.

The honest conclusion isn't that custom is cheaper. It's that the costs sit closer together than people assume, and that the real comparison isn't price against price but who keeps the competitive advantage and control of the system once the project ends.
How much does maintenance influence total software cost?: It's the majority of the cost, and it almost never appears in budget comparisons. According to the IEEE Computer Society, maintenance accounts for 60-80% of a software's total lifecycle cost; Boehm documented in 1981 a typical distribution of roughly 30% development and 70% maintenance. And maintenance doesn't just mean fixing bugs: the foundational Lientz and Swanson study (UCLA) of 487 companies found that roughly 60% of maintenance effort is perfective (improvements, better documentation, more efficient code) and three-quarters of total maintenance is perfective or adaptive—that is, evolving the system as the business changes.

The only source with declared methodology is Accelerance's annual guide, a US outsourcing consultancy: their 2026 guide places LATAM hourly rates at US$33-45 for junior profiles and US$60-75 for seniors; the 2025 guide gave a general range of US$23-90 per hour, with mid-level profiles at US$50-60. The 2026 guide is based on a survey of 60 software development partners worldwide, and the 2025 guide on data from over 100 firms. Three warnings come with the number: it's aggregated LATAM and none of these sources break out Paraguay; Accelerance isn't a neutral source, since it makes money connecting buyers with outsourcing vendors; and LATAM rates fell 7.1% year-over-year in 2025, the steepest decline among surveyed regions, so rate data ages quickly. Olivier Poulard of Accelerance himself warns that hourly rates are a poor measure of real software development cost: a team at US$40 per hour needing three times the hours is more expensive than one at US$70.
