OpenCart Module Development

Custom OpenCart modules and extensions, scoped and priced before we start. OCMOD and event-system only, so your customization survives the next update.

What's included

Base scope of work β€” applies to all tiers. See the tier comparison below for hours and SLA specifics.

Written spec

What the module does, how it is configured, and where it lives in your store, agreed before we write code so the price is a real number.

The module code

OCMOD or event-system code on OpenCart 3 or 4, installed in your store, owned by you with no license strings.

Staging test

Built and validated on a staging copy of your store before anything touches production.

Documentation

A short plain doc on what the module does and how it is set up, so the next developer is not doing archaeology.

How we work

Transparent process β€” you always know what stage we're at and what comes next.

1

Check the marketplace

Before quoting custom, we look for an existing OpenCart extension that does the job. If one does, we say so.

2

Spec and quote

A short call to pin down what the module must do and what it talks to, then a fixed price.

3

Build on staging

OCMOD or event-system code, written upgrade-safe, built and tested on a staging copy.

4

Deploy and hand over

Install on production, confirm it works, hand over the code and a short doc.

Pricing tiers

Pick the level that fits your size and required response time. You can switch tiers between months.

FAQ

How much does custom OpenCart module development cost?

Our brackets run from about $900 for a single focused module to $2,500 for an integration with an outside system, and $6,000 and up for a multi-module build. We quote a fixed price after a short spec call so you are not signing a blank check.

Will the module survive OpenCart updates?

Yes. We use OCMOD modifications or, on OpenCart 4, the event system, and never edit core files. That is the whole point: your customization stays intact when you update.

Do you work with OpenCart 3 and OpenCart 4?

Both. The approach differs (OCMOD on 3, the event system on 4), but we build upgrade-safe on either, and we can advise if you are weighing a move from OC3 to OC4.

What if an existing extension already does what I need?

We will tell you to buy it. Before we quote custom work we check the OpenCart marketplace, and if a cheap extension covers most of your need we will configure it instead of charging you to rebuild it.

Do I own the code?

Yes, outright. The module lives in your store with no license strings and no monthly fee on your own feature.

Can you fix or finish a module another developer started?

Often, yes. We will audit what is there first and tell you honestly whether finishing it or rebuilding it cleanly is the better spend.

Search “OpenCart module development” and you get tutorials. The OpenCart forum, a few YouTube walkthroughs, a 2013 Packt book on how to write a module yourself. All useful if you have a developer with a spare month. Not useful if you run a store and need a feature shipped this quarter without breaking your next OpenCart update.

That is the job we do. We build OpenCart modules and extensions to spec, on a fixed quote, written so the next person who touches your store does not curse our names. OpenCart 3 and OpenCart 4, OCMOD or the event system, no core-file hacks.

Marketplace first, custom second

Before we quote a build, we check whether something on the OpenCart marketplace already does the job. If a $40 extension covers 90% of what you need, we will tell you to buy it and we will configure it, instead of charging you four figures to reinvent it. We only build custom when the marketplace genuinely falls short, which keeps your spend honest and your store lighter.

Upgrade-safe by default

The fastest way to wreck an OpenCart store is editing core files. When the next version lands, your changes vanish or the update fails. Everything we build uses OCMOD modifications or, on OpenCart 4, the event system, so your customization survives upgrades. This is the single biggest difference between a module from us and the cheap freelancer fix that works until the day you update.

What you get

Every module ships with the code in your store, a short configuration doc, and a built-and-tested install on staging before it ever touches production. You own the code outright, no license strings, no monthly rent on your own feature.

Common builds

Payment and shipping integrations for gateways the marketplace ignores. Admin tools that automate a manual task your team does daily. Product-feed and marketplace sync. Custom checkout logic, customer-group pricing rules, and the kind of small workflow fixes that save hours a week. If it is OpenCart and it is reasonable, we have probably built something close.

Many SEO fixes are theme and config work. Start with our OpenCart SEO guide, then bring us the rest.
