## Choosing an e-commerce platform

| Platform | Best for | Watch out for |
| --- | --- | --- |
| Shopify | Fast, reliable D2C stores with standard checkout | Monthly plan and app fees; transaction fees unless you use Shopify Payments |
| WooCommerce | Content-rich stores already on WordPress | Hosting, security updates and plugin conflicts are your responsibility |
| Adobe Commerce / Magento | Large catalogues and complex B2B rules | Higher build and hosting effort |
| Custom (Laravel) | Marketplaces, unusual pricing or deep ERP integration | More build effort; you own every feature |
| Headless | Very fast front-ends and multiple storefronts | Two systems to maintain |

## Costs people forget

- Product data: photos, descriptions and variant setup for every SKU.
- Payment gateway fees per transaction and settlement delays.
- Shipping integrations, returns flow and delivery-area rules.
- Taxes such as GST, VAT and invoices in the required format.
- Monthly platform, theme and app subscriptions.
- Ongoing SEO and marketing to bring the first customers.

## Migrating without losing sales

1. Export products, customers and order history from the old platform.
2. Map every old product and category URL to its new address with 301 redirects.
3. Recreate discount codes, gift cards and customer accounts.
4. Test checkout, taxes and shipping with real orders before switching DNS.
5. Watch Search Console and conversion rate closely for the first weeks.

## FAQ

### How much does an e-commerce website cost?

It depends on the platform, catalogue size, design, payment and shipping rules and integrations. Pick your options on this page and Infikey replies with an estimate for your store.

### Is Shopify or WooCommerce better?

Shopify is quicker to launch and needs less maintenance; WooCommerce gives more control and suits stores that are also content-heavy WordPress sites. The right choice depends on catalogue, budget and who will run the store.

### How much does a multi-vendor marketplace cost compared with a normal store?

More, because sellers need their own dashboards, commissions, payouts and approval flows. Choose "Multi-vendor marketplace" to scope one.

### What monthly costs does an online store have?

Platform or hosting fees, paid apps or plugins, payment gateway fees per order, shipping integrations, and maintenance. These are listed separately in your estimate.

### Can you connect my store to my ERP or Tally?

Yes. Inventory, orders and invoices can sync with most ERP and accounting systems through their APIs or connectors. Tick the integrations you need.
