We build both Shopify stores and custom e-commerce platforms. That means when a Trinidad business owner asks us "Shopify or custom?", we actually have no incentive to lie, we make money either way. So here's the answer we'd give a friend.
The one-line verdict
Shopify if you're under TT$50,000/month in revenue, selling standard products, and you don't need anything unusual. Custom if you're above that, or your business has any one of three specific traits we'll cover below.
That's it. That's the answer. The rest of this is the reasoning.
Where Shopify genuinely wins
Shopify's pitch is that they've solved e-commerce so you don't have to. Payment gateways, inventory, shipping labels, tax handling, emails, all done. You pick a theme, add products, flip a switch, you're selling.
For a starting Trini business, this is legitimately the right answer. If you're selling t-shirts out of your spare room and doing 20 orders a week, do not hire us to build you a custom store. Shopify gets you selling in 3 days for TT$250/month. Spending TT$30,000 on a custom build at that stage is foolish.
Where Shopify quietly costs you
Once your store grows, Shopify starts charging you in ways that aren't on the price sticker.
- Transaction fees. If you don't use Shopify Payments, they take an extra 0.5-2% on every sale. Shopify Payments doesn't process TT currency properly, so Caribbean merchants pay the penalty. On TT$500,000 in yearly sales, that's TT$2,500-10,000/year in fees just for existing.
- App stack. The base Shopify doesn't do much. Real stores run 8-15 paid apps for things like subscriptions, upsells, product filtering, custom shipping. TT$800-2,400/month in app fees is normal.
- Theme upgrade treadmill. Every 12-18 months Shopify updates themes and old ones break. You pay a developer to fix it or buy a new theme. We've seen Trini merchants spend TT$8,000 on "just a quick fix" to theme breakage.
- Platform lock-in. Your URLs, your SEO, your customer data, your historical orders, all shaped by Shopify's structure. Leaving means rebuilding.
When custom pays off: the three triggers
We recommend custom when at least one of these is true:
1. Your business has an unusual flow
Shopify assumes customers browse products, add to cart, pay, wait for shipping. If your actual flow is different, pickup windows, custom orders, subscription boxes with skip-a-month logic, B2B pricing tiers, delivery zones with dynamic fees, Shopify either can't do it or does it through 4 apps held together with tape.
Certified Scoop is a good example. They sell ice cream that has to be picked up or delivered same-day in specific windows. Shopify could do the sale, but couldn't do the "this flavour is only available at South Park Mall between 3pm and 8pm today" logic without hacks. Custom was cheaper long-term.
2. You're spending more than TT$2,500/month on apps
If your Shopify app stack is over TT$2,500/month, you're paying TT$30,000/year for stuff that could be built once into a custom platform and stop renting forever. The math flips.
3. SEO / speed is your primary growth channel
Shopify is.. fine on SEO. Not great. Themes are often bloated (see: that 8-second load time problem). Custom lets us build a site that's genuinely fast, genuinely structured the way Google likes, with the exact schema and URL patterns that match how your customers search. For a Trini business ranking for local terms, custom gives you a real edge.
The middle path nobody talks about
One thing we often recommend: Shopify as the back-end, custom as the front-end. Use Shopify's API for inventory, payments, and orders, but build your actual public site custom. You get Shopify's back-end reliability with a front-end that's actually fast and brand-appropriate.
This is how big DTC brands run. It's what we build when a client wants the best of both. Costs more than pure Shopify, less than pure custom, and the result outranks both.
The straight cost comparison (Trinidad numbers, 2026)
To keep honest, here's what each typically costs a Trini business:
- Shopify off-the-shelf: TT$0 build, TT$250-500/month subscription, TT$500-2,500/month apps. Total year 1: ~TT$15,000-36,000.
- Shopify with premium theme + custom tweaks: TT$5,000-15,000 build, same monthly costs. Year 1: ~TT$20,000-50,000.
- Full custom e-commerce: TT$35,000-90,000 build, TT$500-1,500/month hosting & retainer. Year 1: ~TT$45,000-110,000. Year 2+: only the retainer, no app stack.
- Shopify back-end + custom front-end: TT$25,000-55,000 build, TT$750-2,000/month. Year 1: ~TT$35,000-80,000.
The custom build is more expensive in year 1 and often cheaper by year 3, because you're not renting apps forever. Break-even is usually month 20-30.
What to do next
If you're starting out: Shopify. No debate.
If you're already on Shopify and paying apps: audit your app bill. If it's past TT$2,500/month, consider custom.
If you're planning something with unusual flow (pickup, subscriptions, tiered pricing, delivery zones): talk to someone about custom before you commit to Shopify and fight it for a year.
