The real question isn't build vs buy
The question is: is the way you run this part of the company standard, or is it part of why customers pick you?
Payroll, email, file storage and accounting ledgers are standard. Everybody does them roughly the same way, the rules are set by law or convention, and a SaaS vendor with thousands of customers will do them better than any one-off build. Buy those.
How you schedule crews, price jobs, manage a multi-branch sales team or connect a tenant request to a repair invoice is usually not standard. It's shaped by your market, your history and your people. That's where SaaS starts to bend you out of shape.
Where SaaS wins
- Speed to start: sign up today, use it tomorrow.
- Low upfront cost: monthly fee instead of a project budget.
- Commodity processes: anything regulated or universal, like payroll calculation, bookkeeping or email.
- Small teams: under a handful of users, the maths almost always favours SaaS.
- Proven vendors: security, uptime and compliance handled by a company that does nothing else.
Where custom wins
- Your process is your edge, and forcing it into a generic tool makes you slower or worse at it.
- You run five to fifteen tools that don't talk, and people spend hours copying data between them.
- Per-seat pricing has grown past what a system would cost to own.
- You need permissions SaaS can't model: branches, franchises, subcontractors, clients seeing only their own data.
- You want one place to ask a question about the whole company, not twelve dashboards.
- You need to own the data and the code, with no vendor able to change prices or kill features.
The hidden cost of SaaS sprawl
No single SaaS tool is expensive. The problem is the stack. A typical company of 50 people ends up with a CRM, a project tool, a scheduling app, a forms tool, a document tool, an HR app and a pile of spreadsheets holding it all together.
Each tool has its own login, its own version of the customer, and its own export. The real cost isn't the subscriptions. It's the person who spends every Friday reconciling them, the invoice that never went out because the job was marked done in the wrong app, and the owner who can't answer a simple question without asking three people.
On the homepage we call it Excel files named final_v7, WhatsApp groups, paper job sheets, and 12 tools that don't talk. If that list feels familiar, you're paying for integration whether you bought it or not.
A simple scoring test
Score each area of your company from 0 to 2 on four questions. Is this process specific to us? Do people work around the current tool? Does data from here get retyped somewhere else? Would a mistake here cost real money?
Areas scoring 6 to 8 are candidates for custom. Areas scoring 0 to 3 should stay on SaaS. The middle is where a custom system that connects to your SaaS tools usually makes most sense: keep the accounting package, keep email, and build the operational core that ties them together.
Total cost over five years, not one
Most build-vs-buy comparisons go wrong because they compare year one. SaaS looks cheap in year one because the price is spread out. Custom looks expensive because the price is upfront.
Do the comparison over five years instead. On the SaaS side, add every subscription the area needs, multiply by realistic seat growth, include price rises and add-ons, and add the hours spent moving data between tools. On the custom side, add the build, hosting, and ongoing changes after the included support period.
You'll often find the numbers are closer than they looked, and then the decision comes down to fit and ownership. When the fit is poor and the stack is sprawling, custom usually wins. When the fit is good and the team is small, SaaS usually wins, and you should keep it.
The hybrid most companies end up with
The best setup for most 20–300 person companies isn't pure custom or pure SaaS. It's a custom core that runs the operation, with SaaS kept where it's genuinely better. Accounting stays in the accounting package, but orders and invoices flow into it automatically. Email stays in Google or Microsoft, but the system logs and drafts from it. Payroll stays with the payroll provider, but attendance and shifts are prepared for it.
That's the shape we build at Company Maxxing: one system for the work that makes your company yours, connected to the tools that still earn their place. The rest you can switch off.
Questions to ask before you sign anything
Whichever way you lean, ask the same questions of a SaaS vendor and a custom builder: who owns the data, how do we get it out, what happens to the price as we grow, and what happens if you disappear. The answers tell you more than any feature list.
Risks of going custom, and how to reduce them
Custom has real risks: projects that drag, builders who disappear, and systems nobody but the original developer can maintain.
You reduce them with a fixed price, milestone payments tied to working software, full source code and documentation handed over, and hosting in your own account. You also reduce them by seeing something real early. Our first working version lands within 24 hours of kickoff, running on a sample of your data, and the deposit comes after you've seen it. If you're weighing custom against another SaaS subscription, apply and we'll tell you honestly which side you're on.
