Custom e-commerce and payments
Custom e-commerce that follows your rules, not the platform's defaults.
Most platforms stop where your business starts: split payments, wholesale pricing, carriers and ERP stock. I build custom e-commerce with checkout, orders and inventory that follow your rules, integrated with the payment providers and systems you already use. The result is a store you can operate, not work around.
What the store includes
Checkout and payments
Stripe, Mercado Pago and PayPal connected to the order flow, including installments and local payment methods where needed.
Product and inventory management
A catalog with variants, stock, prices and promotions, kept in sync with what you already sell elsewhere.
Order operations
Order statuses, shipping data, invoices and customer notifications handled in one place instead of your inbox.
External integrations
ERP, logistics and WhatsApp notifications connected through APIs, so stock and delivery status stay accurate.
Performance and reliability
Fast product and search pages on Next.js, with PostgreSQL behind the catalog and monitoring after launch.
Where platforms get in your way
You pay for a plugin for every rule your business already has.
Stock in the store and stock in the ERP never match.
Checkout fails on the payment method your customers actually prefer.
Every new promotion needs a developer or an awkward workaround.
Answers to common questions about working together.
Yes. I work with Stripe, Mercado Pago and PayPal, and I can add another provider through its API. During scoping I check fees, settlement times and what the provider supports in your country.
Not necessarily. Sometimes extending Shopify is the cheaper answer and custom software is not worth it. I compare both on effort and control, then recommend the option I would choose in your position.
It depends on how many products, payment methods and integrations are involved. A first version can often go live before every feature is finished, and I send a scope-based timeline after a short call.
