The problem

Most online stores lose sales every day.

Many entrepreneurs launch an online store without truly understanding what makes it sell. It looks decent, the products are there - but visitors don't buy, carts get abandoned and the processes behind the scenes are managed manually.

The most common issues we find on existing stores:

Conversion rate is low

The traffic is there, but the sales aren't. Most of the time the problem isn't the product - it's the buying experience. A complicated checkout flow, slow pages or a design that doesn't inspire trust are enough to make a visitor leave without buying.

Integrations are missing or done manually

Without working connections to payment systems, couriers and invoicing, every order becomes manual work. Copying data between systems, generating invoices separately, updating stock by hand - time lost that grows in direct proportion to order volume.

The platform is holding you back

What worked at 50 products doesn't work at 500. The platform chosen at the start becomes a constraint: it doesn't support the integrations you need, behaves unpredictably under high traffic or maintenance costs keep rising without performance following.

Every change goes through the agency

If adding a new product or updating a price requires technical help, something was built wrong. A well-built online store should be manageable by your team - without calling the agency for every small change.

Our solution

An online store built to sell.

The first step isn't choosing a platform - it's understanding your business. We start with a real analysis: what you sell, how you plan to scale, what integrations you need and what the ideal buying experience looks like for your customer. Only then we decide which technology best serves your goals.

We don't recommend the same solution for every project. Shopify is the right fit for businesses that want to launch fast, with an intuitive interface anyone on the team can use without technical training. WooCommerce offers greater flexibility and full control over infrastructure. A custom solution is the answer when neither standard platform covers what you need.

Our approach
At GMG we believe a good online store doesn't end at launch - it's built continuously, based on real data about how your visitors buy.

Every store we build is fully integrated - payments, shipping, automatic invoicing, stock synchronisation. We don't deliver a store your team manages with anxiety - we deliver a platform they understand and can use independently from day one.

At the end you get more than a functional store. You get complete documentation, full access to all accounts and platforms, and an architecture built to grow with your business - without depending on us for every small change.

What you get

A fully built online store. From strategy to launch.

Every e-commerce project delivered by GMG includes everything an online store needs to function, sell and be managed independently - from architecture and design to integrations, performance and full documentation.

Conversion-focused design

When someone lands in your store, they have already made part of the decision. The design has one job: not to get in their way. We build clear, fast interfaces with optimized checkout flows and product pages designed to support the buying decision - so visitors buy, instead of dropping off before they complete the order.

Seamless integrations

An online store without reliable integrations creates unnecessary work with every order. We connect your platform to payment gateways, shipping providers, automated invoicing, and any other tools in your operational workflow. Everything works together. Inventory updates automatically, invoices are generated instantly, and orders move forward without you having to manage every step manually.

Intuitive admin interface

You should be able to add a new product, change a price, or update inventory without calling your agency or knowing what a CMS is. We deliver an admin interface your team can start using from day one - and we document everything you need so you can stay independent after launch.

E-commerce migration

If you already have an online store and want to move to a better platform, we handle the transition without losing your data, orders, history, or the SEO authority you have built over time. We assess your current setup, plan the migration carefully, and execute it in a controlled way - with no downtime and no unpleasant surprises.

Performance & security

A slow store loses customers before the first image even loads. We optimize for real-world speed - Core Web Vitals, fast response times, and consistent performance across all devices. Security is built in from the start: SSL, automated backups, protection against unauthorized access, and continuous monitoring.

Tracking & analytics

You know how many visitors you get. But do you know how many abandoned their cart at step three of checkout? Or which traffic source is driving actual orders, not just clicks? We implement advanced e-commerce tracking - including sales monitoring, conversions, cart abandonment, and purchase behavior - so your business decisions are based on real data, not assumptions.

Frequently asked questions

Everything you need to know about online stores and e-commerce.

We answer the most common questions about our process, the right platform, integrations, migration, maintenance, and what you receive at the end. If you cannot find what you are looking for here, we are just a message away.

An online store build includes everything you need to start selling, not just a website that looks good. It covers the store structure, design, product and category pages, checkout, integrations with payments, shipping and invoicing, plus the admin side behind it. In short, you do not just get an interface. You get a complete system, ready to run and ready for your team to use from day one.
An online store that sells makes buying easy. Products are easy to find, key information is clear, pages load fast, and checkout takes as few steps as possible. The difference shows in practical details: strong product descriptions, useful filters, clearly displayed payment and delivery options, a simple checkout, and a buying process that feels trustworthy.
You build a new online store when you are starting a new business or when your current store has core issues that are no longer worth fixing. That usually means a platform that is holding you back, missing integrations, poor performance, or a system that is difficult to manage. In those cases, a new build is more efficient than continuing to patch a weak foundation. You improve an existing store when the core setup still works, but certain areas need a fix. That can mean a design refresh, better page structure, a smoother checkout, faster load times, clearer information, or easier day-to-day management. The goal is to improve performance without rebuilding the whole store from scratch.
Because traffic does not guarantee orders. If the store is slow, products are hard to find, information is unclear, or the buying process feels complicated, many visitors leave without completing a purchase. Trust issues matter just as much: clear delivery and return policies, enough payment options, transparent costs, and a simple checkout. If people do not quickly understand what they are paying, how delivery works, or how returns are handled, abandonment goes up fast.
The process starts with an analysis phase where we understand your business, what you sell, how you deliver, what integrations you need, what your goals are, and what the real project budget looks like. Only after that do we decide on the right solution: Shopify, WooCommerce, or a custom build. We do not recommend technology that makes no sense for the stage your business is in. Once the direction is clear, we move into structure, design, development, and integrations - payments, shipping, invoicing, stock management, or any other systems your store depends on. At the end, we test everything, launch the store, and hand it over in full, with access, documentation, and a system your team can use without relying on us for every small change.
The timeline depends on the complexity of the project. A simple online store with a small product range and no special requirements can be ready in as little as 2 weeks. A more complex project can take up to 10 weeks, especially if it includes a large catalogue, multiple integrations, custom functionality, or more advanced user flows. For a custom online store, the timeline can be longer depending on what needs to be built. We set the exact timeframe after the analysis phase, once we know what you need, which integrations are involved, and how complex the right solution is for your business.
We need a clear understanding of your business: what you sell, who you sell to, how many products you have, how you deliver, which payment methods you want to offer, what integrations you need, and what you want the store to achieve. It also helps to know from the start whether you already have product images, descriptions, and product structure in place, or whether you need support with that as well. If you are at an early stage and you do not yet have a clear position in the market, a visual direction, or a clear way to present your products, we can include a branding package too. That way, the store is not just functional - it also starts with a clear foundation for brand and communication.
Yes. An existing online store can be migrated without losing products, orders, or Google rankings, as long as the process is handled properly. Migration involves more than just moving products. In practice, it can include database transfer, moving products, orders, and customer accounts, keeping or rebuilding important URLs, and setting up the right redirects so old pages do not disappear or affect your visibility in Google. As part of the migration process, we also make sure the new store takes over the essential data correctly and works as it should after launch. When done properly, migration lets you move to a better solution without losing the history and value you have already built.
At the end of the project, you receive everything that was built for your online store: the live store, the source code, access to the accounts and platforms used, and all materials created as part of the project. If we created the copy or graphic assets, you also receive the rights to use them. In short, nothing stays locked on our side. You get full control over the store, the accounts, and the assets created for your business.
You own everything built for your business: the store, the accounts, the graphic assets, and the copy created as part of the project. If we create the design, the copy, or any other materials, the usage rights are transferred to you at the end of the project. The only exception is the platform itself. For example, if the store is built on Shopify, you own the store, the account, and its content, but the platform itself remains Shopify's and runs on a subscription model. The same applies to third-party apps or licensed services: you keep access and control over your accounts, but their use depends on each provider's terms and subscription plans.
Yes. At the end of the project, we show you how to use the store and handle the essential admin tasks: adding products, updating prices, managing orders, updating stock, or any other actions that matter for your team. On top of that, you receive written or video documentation, depending on the project and what is most useful in practice. The goal is for your team to be able to use the store correctly and independently after launch.
Yes. A properly built online store should be manageable by your team without technical help for day-to-day tasks: adding products, changing prices, updating stock, editing content, or managing promotions. If you prefer, we can also handle the updates and changes related to the store, so your team does not have to spend time on that side of the work. The only part that stays with you is order processing, because that is directly tied to your business operations and internal workflow.
After launch, maintenance can include technical updates, monitoring, backups, security checks, bug fixes, and any work needed to keep the store running properly. If the store runs on a platform such as WordPress / WooCommerce, this also includes plugin, theme, and platform updates, handled carefully so they do not break what is already working. Depending on what you need, maintenance can also include content updates, changes to pages, products, banners, or other adjustments inside the store. The goal is to keep the platform stable, secure, and easy to use over time.
The right choice depends on what you need now, how complex the store is, and what budget you have available. Shopify is a good fit when you want to launch faster and have a platform that is easy to manage. WooCommerce offers more flexibility and is a strong option if you want more control. A custom build makes sense when you have specific requirements, complex integrations, or a business model that standard platforms do not handle well. There is no single right option for everyone. The right solution is the one that fits your stage of growth, the actual needs of the store, and the budget available.
Yes. An online store can be integrated with the systems it needs to run properly: online payments, shipping providers, invoicing, notifications, or any other tools used in your workflow. The goal is to make the process as simple and automated as possible, both for your customers and for your team. We choose and implement the integrations based on the store platform and what makes sense for your business.
Yes, in many cases an online store can be integrated with marketplaces. That can include syncing products, stock, prices, or orders, depending on the marketplace and how the integration is supported. Whether the integration is possible depends on two things: the platform your store is built on and the marketplace you want to connect to. That is why, before implementation, we check clearly what each side supports and choose the option that makes sense for your business.
Checkout is optimised by making the ordering process as simple as possible: fewer steps, shorter forms, fast pages, and clear information. It also helps to offer enough payment options, show costs clearly, and make the order flow easy to understand from the start. Cart abandonment usually happens when there is friction: unexpected costs, unclear delivery details, forced account creation, a complicated checkout, or a lack of trust. To reduce abandonment, checkout needs to be simple, fast, and clear, and the customer should immediately understand how much they are paying, how delivery works, and what their return options are.
Yes, but it depends a lot on the platform you choose and how the store is built from the start. Some platforms handle growth well, while others start to become limiting when the number of products, orders, integrations, or more advanced functionality increases. That is why, from the start, we look not only at what you need now, but also at how your business is expected to grow. If the store eventually outgrows the current platform, the solution is a controlled migration to a better fit, without losing what you have already built.
