Custom software vs SaaS, a guide for Belizean businesses

Most weeks someone asks me a version of the same question. Should we pay a monthly subscription for something that already exists, or should we have something built for us. The custom software vs SaaS choice (SaaS means software as a service, a hosted product you rent by the month instead of owning) is not a matter of taste. It depends on how standard your process is, how soon you need to start, and whether the rules you work under are Belizean rules.

I build both. From my own Linux servers in Belize I run several hosted products that organisations subscribe to, and I also build bespoke systems for one client at a time. So I have no reason to push you in either direction. What follows is how I would reason it through if you were sitting across the table from me.

What you are actually choosing between

There are three real options, not two.

1. Keep doing it by hand. Spreadsheets, WhatsApp, paper files, a shared folder. This is cheaper than people admit in the first year and more expensive than people admit in the third.
2. Rent a hosted product. You sign up, you configure a few settings, you start this month. You pay as you go and you do not own the code.
3. Commission a custom system. It is built around your process, you keep the source code (the human-readable instructions that make the software work), and you decide what changes next.

There is also a fourth option that sits between two and three, and in Belize it is often the right one. I will come back to it.

When is off-the-shelf SaaS the right choice?

Choose a hosted product when your process is genuinely standard and you want to be working inside a system within weeks rather than months.

If you are a small agency that needs listings on a website, a shared contact list and a record of who spoke to which buyer, that is a solved problem. There is no competitive advantage in a bespoke version of it. The same applies to a school that needs enrolment, marks and report cards, or a small employer that needs to run a fortnightly payroll correctly.

Signs a hosted product fits:

• Your process looks like everyone else's in your industry, and you are content with that.
• You need to start now, with a predictable monthly cost rather than a project budget.
• You do not have anyone internally who will own a software project.
• The volume of data is modest and the rules are simple.

The honest trade-off is that you adapt to the product. If the product does not do something, you wait, or you work around it in a spreadsheet.

When should a Belizean business choose custom software?

I would argue for custom in three situations.

The process is your advantage. If the way you price, schedule, underwrite or dispatch is the reason customers choose you, do not flatten it to fit someone else's form. A loan servicing book with unusual terms, a rental operation with its own deposit and damage rules, a survey programme with a particular sampling design. These are worth modelling properly.

Regulation or data residency matters. Data residency means where your records physically live and whose laws apply to them. A public body, a lender or a school holding minors' records may need to know that the server is here, or at least that it is under a contract you control. I run systems on hardware I manage, and I can tell a client exactly where their database sits.

Foreign SaaS does not model Belizean rules. This is the one that catches people. Social security and income tax deductions, BZD and USD on the same invoice, GST handling, filing to the Belize Tax Service. Most foreign products were never built for any of it. I have written a bridge that takes QuickBooks Desktop data to the web and handles e-invoicing filing precisely because the gap is real.

Is custom software more expensive than SaaS?

Up front, almost always yes. Over five years, often no, and sometimes the comparison is not about money at all.

A subscription is small each month and continues forever, for every user, with price rises you do not control. A custom build is a project cost, then a smaller ongoing cost for hosting, backups and changes. Somewhere between year two and year four the lines usually cross, and they cross sooner when the hosted product forces staff into double entry or manual reconciliation.

The cost nobody puts in the spreadsheet is the work-around. An hour a day of someone retyping figures from one system into another is a real salary line, and it never appears on the invoice from the vendor.

The middle path, a product built for Belize

The fourth option is a multi-tenant product designed for local rules. Multi-tenant means one piece of software serving many organisations, each with its own data, branding and settings, kept strictly separate. You get the speed and price of a subscription, but the product already understands the things a foreign vendor never modelled.

That is how I have built most of what I run. One codebase, many clients, configured per organisation, which I have written about in more detail in how multi-tenant architecture works in practice. Propzy powers several agency websites and their shared CRM, a system for tracking contacts and deals. EasiMan handles HR and payroll with Belizean deductions built in rather than bolted on. Scholar runs a school, Direct Belize runs hotel sites with direct booking and channel sync, Mortgage Base handles loan servicing.

When a client on one of these needs something specific, I can often add it as a configurable option rather than a bespoke fork. That is the compromise working as intended.

Four questions to ask any vendor, including me

Before you sign anything, ask these and write the answers down.

1. Who owns the data? The answer should be you, in writing.
2. What happens if the vendor disappears? If I were hit by a bus, could your IT person or your next developer pick this up. With source code, documentation and in-app help handed over, the answer is yes. Without them it is no.
3. Can you export everything, today, without asking? Not a PDF report. A full export of your records in a format another system can read.
4. Who pays for changes, and how fast do they happen? On a hosted product you are in a queue with everyone else. On a custom system you are the queue, and you are also paying for it.

A short comparison

| Question | Hosted product | Custom build | | --- | --- | --- | | Time to start | This month | A few weeks to a few months | | Cost shape | Monthly, forever | Project, then smaller upkeep | | Fit to your process | You adapt | It adapts | | Belizean payroll, tax, BZD/USD | Only if built here | Yes, by design | | Source code and ownership | Vendor keeps it | You keep it | | Who decides what changes next | The vendor | You |

Where to start

Four practical steps, in order.

1. Write down the process you want to fix, in plain language, as the steps a person takes today. One page is enough.
2. Count the manual handling. How many times is the same figure typed twice, and by whom.
3. Try a hosted product first, where one exists that understands Belizean rules. If it fits, you have saved yourself a project.
4. If it does not fit, note exactly where it broke. That list is the specification for a custom build, and it will save you money when you commission one.
