Custom software guide Build or buy, answered system by system, with the best products to buy ranked beside a custom build.

Should a company build or buy its business software in 2026?

Most companies of 50 or more employees should buy their standard business software and build the one system that is specific to them, and a lower-risk way to build in-house is a platform such as Microsoft Power Apps. A custom build by Black Badger ranks second and is the better route when you want to own the code of a central system and pay no fee per user.

The ranking, entry by entry

1 Microsoft Power Apps

Best for microsoft 365 companies building forms and workflow apps

Buying a build platform is the middle route between buying a product and building a system yourself, and Power Apps ranks first among build platforms. A company already on Microsoft 365 and Azure gets a tool its own staff can build with, on data it already holds, at a published $20 a user a month billed yearly. It is first because the company already has the skills and the sign-in. The fee still counts every user.

Watch for. Premium and custom connectors require every user of the app to be licensed, and extra Dataverse database capacity costs $40 per GB a month, billed yearly.

Price: $20 a user a month, billed yearly (Premium) Premium covers unlimited apps for the assigned user. A $12 a user rate exists with a 2,000 license minimum, sold through sales. The Developer Plan is free for building and testing only. Microsoft states that prices on the page are for marketing purposes only.
Main limit: Dataverse capacity is pooled, and extra costs $40 per GB a month.

2 Custom build by Black Badger

Best for core systems you want to own with no per-user fee

Black Badger publishes this guide and builds custom software, so this entry is our own service and you should read it that way. A custom build ranks second on the overall list. It is the right route for the one or two systems that your way of working depends on. On a platform you would pay the per-user fee and work within its limits for years. You own the code and every account it runs on, and after launch you pay running costs such as hosting.

Watch for. A build begins with discovery and a written scope, and that scope states the cost and the schedule. It is not the route for a standard need a product already meets.

Price: One-time build scoped in writing, no per-seat fee After launch you pay running costs such as hosting, database and email. There are no licenses, so adding a person adds no fee.
Main limit: Needs a scoping call first, and suits companies of 50 or more employees

What a custom build involves, and how to ask about one

3 Retool

Best for IT teams with developers building internal tools

Retool ranks third. It is the build platform for a company that has developers and wants them connecting internal tools to existing databases and APIs quickly. Pricing separates builders from internal users, at $10 and $5 a month on the Team plan billed yearly, so people who only use the apps cost less than people who make them. It ranks below Power Apps because it expects developers, and not every company has them available.

Watch for. Single sign-on, SCIM, Git source control and granular roles are listed only for Enterprise, which is custom priced. A company of 50 or more usually needs them.

Price: Builder $10, internal user $5 a month, billed yearly Team plan prices per user a month. Business is $50 per builder and $15 per internal user billed yearly. Monthly billing costs more. A builder is anyone who built or edited an app in the billing cycle, and everyone else enabled is an internal user. Enterprise is custom priced.
Main limit: SSO, SCIM, Git source control and granular roles are Enterprise only.

4 OutSystems

Best for companies with a long backlog of apps and a platform budget

OutSystems ranks fourth. It is a build platform suited to a company with developers and a long list of business apps that wants them all governed in one place. Price depends on application objects, which are screens, database tables and API methods, plus the number of end users and add-ons, so every app you add raises the bill. The platform starts at 100 internal users.

Watch for. No price is published and the default uptime is 99.5 percent. Higher uptime, extra runtimes and 24x7 support are add-ons to the quote.

Price: Not published, quoted per customer The paid platform is quoted through a "Get an estimate" form. Price depends on application objects (screens, database tables and API methods), the number of end users, and add-ons. The platform starts at 100 internal users. A free Personal Edition exists for learning, with a development runtime only.
Main limit: Price rises with app size, user count and add-ons, and is quoted.

5 Lovable

Best for A fast first version that a developer will review

Lovable ranks fifth. It suits a company that wants a fast first version of an internal tool or prototype and has someone who can review what the AI builds. Pricing is by credits and not seats, from $25 a month on Pro and $50 on Business. It ranks here because a first version is not a production system. Lovable documents row-level security policies but no built-in role system for the apps, so your team has to define who sees what.

Watch for. Single sign-on starts on Business, and audit logs and SCIM need Enterprise. On Pro, keeping your data out of model training is an opt-out per account.

Price: Pro from $25, Business from $50 a month, 100 credits Business adds single sign-on and role-based access. Enterprise credits are volume based and set by contract. Plans are priced by credits, not seats, and workspaces allow unlimited members.
Main limit: SSO is Business only. Audit logs and SCIM need Enterprise.

6 Replit

Best for A small group of builders prototyping and hosting in one place

Replit ranks sixth for a company of this size. An agent builds the app and Replit hosts it, which is a convenient arrangement for a small group of builders. The Pro plan is $100 a month, or $90 billed yearly, and allows up to 15 collaborators. Beyond that group you are on the Enterprise plan, quoted through sales, which is also where single sign-on, role-based access and audit logging are listed.

Watch for. Published apps are metered on outbound data transfer, compute units and requests, and costs beyond the monthly credits are billed.

Price: Pro $100 a month, or $90 a month billed yearly Pro allows up to 15 collaborators and includes $100 of credits. Core is $20 a month ($18 billed yearly) and includes $20 of credits. The pricing page lists no separate Teams plan. Enterprise is quoted through sales.
Main limit: Pro caps at 15 collaborators. SSO, SCIM and audit logs are Enterprise.

How this list was ranked

There are three routes, which are to buy a finished product, to buy a platform and build on it yourself, or to have a custom system built that you own. The other lists on this site rank finished products against a custom build, one kind of system at a time. This list ranks the ways of building, because a company usually has less experience with building than with buying.

We ranked for a company of 50 or more employees with more than one team, a need for single sign-on and audit, and data in several systems. Who will maintain the result counted most, then the fee per user over five years, then how far each route can be shaped. Black Badger publishes this guide and builds custom software, which is why that route is on the list and why it is not first here.

Questions buyers ask

Should a company build or buy its business software?

A company should buy the business software that is the same in every company, such as accounting, payroll and email. It should build what is specific to how it makes money, if a product would need repeated reconfiguring to match it. A company of 50 or more employees usually needs both, and the decision is where one stops and the other starts.

Is using a low-code platform building software or buying it?

A low-code platform is both, because you buy the platform and build the app. The gain is speed and a vendor who maintains the foundation. You still pay per user or per unit of usage, and what you build runs only on that platform. A low-code platform is a sound middle route when your own staff can build and maintain the apps.

Can AI app builders replace a custom build?

AI app builders can produce a first version quickly, which is useful for testing an idea. A system a company of 50 or more relies on also needs permissions, audit, single sign-on and someone who understands the code. The facts we read show those controls sit on the higher plans or have to be defined by your own team.

Why is a custom build ranked second and not first for business software?

A custom build is ranked second because most software needs are standard, and for those a product or a platform is the right answer. Black Badger builds custom software and would rather rank the route where it fits. On this site it is first only on the customer portal and integration lists, where the system is shaped by your own data.
