How to compare software development companies
Custom software can run a core part of a business for years, so a developer's engineering habits, contracts and data handling matter as much as the first release. This page covers what to check by market and how we assess developers.

What software developers do
Software development spans bespoke business systems, mobile and web applications, integrations between existing tools, and engineering teams supplied to work under the client's direction. Projects tend to run longer and less predictably than website builds, and the cost of a poor choice often shows up after launch, in defects, security gaps or code nobody else can maintain. A capable supplier can show how it works: version control, code review, automated testing, documented architecture and a defined process for fixing vulnerabilities once the software is in use.
The commercial model matters as much as the technical one. On a fixed-scope project the supplier carries more of the delivery risk; with a dedicated team or time-and-materials arrangement the client directs the work and carries more of it. Whichever model you choose, three contract terms deserve early attention: who owns the source code and related intellectual property, how personal data is processed and secured, and how you can take the code and documentation elsewhere if the relationship ends.
Systems built around a company's own processes, such as scheduling, quoting, inventory or case management, where packaged software does not fit.
Native or cross-platform apps for iOS and Android, including app store submission, notifications and connection to back-end services.
Browser-based software-as-a-service products with user accounts, subscriptions and separated customer data, often built for a client to sell on.
Connecting accounting, customer relationship management and payment tools through application programming interfaces (APIs) and scheduled data exchange.
Engineers supplied full-time to work under the client's direction, billed monthly per person, with the supplier handling employment and equipment.
Rewriting or restructuring ageing systems, migrating their data and moving workloads to cloud hosting while the business keeps running.
Bug fixes, security patches, dependency updates and small enhancements under agreed response times once the software is live.
What to check in your market
Rules differ by country. Choose a market to see the licences, registers and complaint routes that apply there.
United States
Ownership of custom code is the first US question. The person who creates a work is ordinarily its author, and commissioned work only becomes a work made for hire in nine listed categories with a signed agreement, so outsourced code needs a written assignment. The Federal Trade Commission (FTC) advises businesses to vet a provider's security, write requirements into the contract and verify compliance. California's privacy law places separate duties on service providers, and its regulations on automated decision-making, risk assessments and cybersecurity audits took effect on 1 January 2026.
Include a clause assigning copyright in all source code and documentation to you, since computer programs are not among the nine categories listed for commissioned works made for hire.
copyright.govAsk how the supplier protects your data, set those requirements in the contract and require it to report security incidents, as FTC guidance recommends.
ftc.govIf your business falls under the California Consumer Privacy Act (CCPA), confirm the developer accepts the obligations the law places on service providers and contractors.
cppa.ca.govIf you are commissioning an app as an individual, note your state consumer protection office before signing in case the supplier stops responding.
usa.gov
Where a business commissions software, the contract's dispute resolution clause, governing law and limitation of liability decide the route, so agree a stepped process of negotiation, mediation and then arbitration or court. Individuals who commission an app for personal use can also contact their state consumer protection office, which helps with complaints against businesses.
United Kingdom
UK GDPR requires a written contract every time a controller uses a processor, which applies whenever a developer handles personal data on your behalf. The Information Commission (ICO) notes its controller and processor guidance is under review after the Data (Use and Access) Act. Cyber Essentials, developed by the National Cyber Security Centre (NCSC), is the government-recommended minimum standard of cyber security for organisations of all sizes. When an individual contractor works through their own company, the off-payroll working rules (IR35) decide who determines their employment status.
Sign a written processing contract before the developer touches personal data, setting out your instructions, security measures, any sub-processors and what happens to the data at the end.
ico.org.ukAsk whether the supplier holds Cyber Essentials or Cyber Essentials Plus, and confirm the certificate through the search linked from the NCSC page.
ncsc.gov.ukIf a contractor works through their own limited company and you are a medium or large client, produce a status determination statement giving your reasons.
gov.uk
A late or failed software project is a contract matter. Set out your complaint to the supplier in writing, propose mediation, and if neither works, use the county court money claim process covering England and Wales. Claims that rest on detailed technical evidence may need specialist legal advice before you issue them.
UAE & GCC
The UAE's federal data protection law, Federal Decree-Law No. 45 of 2021, has been in force since 2 January 2022 and prohibits processing personal data without the owner's consent, subject to exceptions. The Dubai International Financial Centre (DIFC) has its own Data Protection Law, DIFC Law No. 5 of 2020, so check which regime covers your company and the developer. Software, smart device applications and databases are protected under the UAE's 2021 copyright law, and the Ministry of Economy and Tourism registers intellectual works.
Search the supplier's trade licence on the federal National Economic Register, or on the Abu Dhabi or Dubai enquiry service, and confirm it is current.
u.aeAgree in writing how the developer will process personal data, covering consent, security and deletion, in line with Federal Decree-Law No. 45 of 2021.
u.aeIf either party is based in the DIFC, confirm whether the DIFC Data Protection Law applies to the project's personal data.
u.aeState in the contract that copyright in the code and databases passes to you, and consider registering key software with the Ministry of Economy and Tourism.
u.ae
Individuals who buy an app or software service can use the Ministry of Economy and Tourism's consumer complaints channel or the economic department in their emirate. For company buyers, redress follows the contract, so specify the governing law and whether disputes go to court or arbitration, and in which emirate or free zone.
International
Outsourcing development to another country raises three practical questions: which law governs the contract, how personal data may lawfully leave your jurisdiction, and whether a judgment or award could be enforced where the supplier is based. For personal data leaving the EU, the European Commission's standard contractual clauses provide one recognised safeguard. Arbitration awards benefit from the New York Convention, under which courts recognise and enforce foreign awards much as they do domestic ones. Agree overlapping working hours and named escalation contacts across time zones as well.
If the team will access personal data from the EU or European Economic Area, attach the European Commission's standard contractual clauses to the contract.
commission.europa.euAsk where every engineer and subcontractor is located, since each location can change which data transfer safeguards the contract needs.
commission.europa.euBefore choosing arbitration, check that the supplier's home country is a party to the New York Convention, so an award can be enforced where its assets are.
uncitral.un.org
Redress abroad depends on the forum named in the contract. Under the New York Convention, courts in member countries must honour a valid arbitration agreement and generally enforce the resulting award. Milestone payments, source code escrow and a repository under your control limit what is at stake before any dispute begins.
How we assess software developers
These are the editorial criteria behind every software developer we rank, with the weight each carries in the editorial score. The editorial score makes up 60% of a ranking and adjusted customer ratings the other 40%, as set out in how we rank.
| Criterion | Weight | What we look at | Evidence we accept |
|---|---|---|---|
| Engineering practice | 25% | Version control, code review, automated testing, documentation and release processes, judged on how the developer actually works rather than how it describes itself. | Anonymised code samples, test coverage reports, architecture documents, release notes and a walkthrough of the team's build pipeline. |
| Security and data handling | 20% | Secure development practice, vulnerability handling and protection of client personal data. Weighted highly because custom code often processes personal or commercially sensitive data. | Checkable security certificates, alignment with a recognised secure development framework, data processing terms and a route for reporting vulnerabilities. |
| Contracts, IP and pricing | 20% | Whether estimates, rate cards, change control and ownership of code and data are set out in writing before work starts. | Master services agreement, statement of work template, intellectual property assignment clause, exit and handover terms, and sample invoices. |
| Delivery and continuity | 15% | A record of shipping on agreed timelines and keeping teams stable, plus plans for handover if key staff or the supplier change. | Client references contacted directly, staff turnover disclosures, planned against actual delivery dates, and a documented handover process. |
| Communication and governance | 10% | Reporting rhythm, access to the people doing the work, overlap of working hours and a clear escalation path when problems arise. | Sample status reports, meeting schedules, named account and technical leads, and a written escalation route. |
| Entity and certifications | 10% | A registered, traceable business with verifiable certifications. Weighted lower because registration shows who is accountable, not whether the engineering is sound. | Company register or trade licence entry, certificate numbers that can be checked, and named directors or owners. |
Before you hire
Questions to ask
- Will we own the source code and documentation as they are produced, or only after final payment?
- Which parts of the system reuse your own libraries, and what licence do we receive for them?
- How do you test code before release, and can we see a recent test report?
- Where will our personal data be stored and accessed, and by which subcontractors?
- Who are the named engineers on our project, and how much notice do we get before they change?
- How are scope changes estimated, approved and billed during the project?
- What happens to our code, credentials and documentation if either side ends the contract?
- How do you handle security vulnerabilities found after the software goes live?
Red flags
- Code kept in the supplier's private repository, with access promised only after final payment.
- A fixed price for a complex system quoted before any discovery or requirements work.
- Refusal to name the engineers, or a team that changes without notice after the sales stage.
- No data processing terms, even though the software will hold customers' or staff members' personal data.
- Ownership terms that leave the supplier holding the copyright and grant you only a licence.
- Work subcontracted to other firms or countries without telling you or seeking consent.
- Open-ended hourly estimates with no cap, progress reporting or approval step for overruns.
How pricing works
Software is usually priced on time and materials, as a fixed price for a defined scope, or as a monthly fee per dedicated engineer. Rates vary with location, seniority and technology, so compare suppliers on the whole estimate rather than the hourly figure. A lower rate tells you nothing about how many hours the work will take, how much rework it will need, or how easily another team could maintain the result.
Ask for estimates broken down by feature and phase, with assumptions stated. A paid discovery phase that produces requirements, an outline architecture and a revised estimate reduces the risk of a fixed price built on guesswork. After launch, budget separately for hosting, third-party services, monitoring and a support agreement with defined response times, as these costs continue for as long as the software runs.
- Time and materials
- Hours or days billed at agreed rates; flexible when requirements will change, but needs budget caps and regular reporting.
- Fixed-price project
- One price for a specified scope and timeline; the supplier carries delivery risk, and changes go through formal change requests.
- Dedicated team
- A monthly fee per engineer working under your direction; you set priorities and carry more of the delivery risk.
- Paid discovery phase
- A short, separately priced stage producing requirements, architecture and a firmer estimate before the main build.
- Support agreement
- A recurring fee for maintenance, security patches and fixes within agreed response and resolution times.

Questions about software developers
Who owns the code a software company writes for me?
It depends on the contract and the law that governs it. In the US, computer programs are not among the categories of commissioned work that can be made for hire, so a written assignment is the reliable route to ownership. In the UAE, the 2021 copyright law protects software, applications and databases, and the contract should say who holds those rights. In any market, ask for an express assignment and a list of pre-existing components that remain licensed.
Is a dedicated team cheaper than a fixed-price project?
Not necessarily. A dedicated team bills for time whether or not features ship, so the cost depends on how well you set priorities and manage the work. A fixed price moves delivery risk to the supplier, who will price that risk in and control change requests closely. Starting with a paid discovery phase, then choosing a model once the scope is clearer, keeps the decision grounded in evidence.
Do I need a data processing agreement with my developer?
If the developer will host, access, test with or support systems holding personal data for you, UK GDPR requires a written contract every time a controller uses a processor. In the US, the FTC advises writing security expectations into provider contracts and checking them, and California's privacy law places separate duties on service providers. In the UAE, Federal Decree-Law No. 45 of 2021 applies, and the DIFC has its own data protection law.
How does Top8Reviews assess software developers?
Engineering practice carries the largest weight at 25%, followed by security and data handling and by contract, intellectual property and pricing clarity at 20% each. Delivery and continuity counts for 15%, with communication and registration at 10% each. We ask for evidence such as code samples, test reports and client references, and customer reviews stay separate from the editorial score. No rankings publish until businesses have been assessed.
Can an offshore development team work safely?
It can, when the contract and working arrangements make up for the distance. Find out where staff and subcontractors are based, put data transfer safeguards in place, choose a dispute forum whose decisions can be enforced in the supplier's country, and keep the code in a repository you own. Agree overlapping hours and a named escalation contact so problems surface early rather than at the final milestone.
