Software that has to hold on the busiest day of the year
Retail software is judged in November. The rest of the year you can work around a slow integration or a manual step, and then one weekend arrives where every one of them costs real money.
FusionHit builds commerce and store systems with senior engineers across Latin America who have been through a peak season and know what breaks first. They work US Central and Eastern hours, so load testing, a freeze decision or an incident during your trading day happens with the team that wrote the code.
\ Retail systems we build
The systems our clients bring us most often, each one built around the channels, the store and the stock behind them.
Ecommerce and storefronts
Custom storefronts and the work around a commerce platform: checkout, promotions and the parts your team keeps having to work around.
Order management
One view of an order across web, store and marketplace, with the sourcing, split and return logic that makes it true.
Inventory and merchandising
Stock accuracy across locations, allocation and replenishment, and the product data everything else reads from.
Point of sale and store operations
Store applications, tasks and clienteling, built for the hardware on the counter and for staff turnover.
Customer apps and loyalty
Apps, loyalty and the account experience that has to look the same in store and online.
Integrations across the stack
Commerce platform, ERP, POS, payments, tax, shipping and marketplaces, connected so numbers match everywhere.
Retail analytics
Margin, sell-through and stock position reported on data your systems already produce.
Replatforming and modernization
Moving off a platform or a custom system that has stopped keeping up, without losing a trading day.
The retailers we build software for
Different formats, different failure modes. These are the ones our engineers already know how to work with.
Multi-store retailers
Stock, pricing and tasks across locations that each behave a little differently.
Direct to consumer brands
A storefront, a subscription or a launch model that a platform alone will not support.
Grocery and convenience
Perishables, substitutions and fulfilment windows, where inventory accuracy is the whole job.
Specialty retail
Complex products, configuration or fitting, where the sale needs more than a cart.
Wholesale and distribution
B2B ordering, pricing by customer and the ERP behind it.
Marketplace sellers
Listings, stock and orders across channels that each want their own format.
How we work around the season your year depends on
Every vendor promises scalability. None of them tells you what they do in the eight weeks that actually matter. This is what we agree before the calendar gets close.
We set the code freeze date with you, usually several weeks before your peak, and what still ships during it: security fixes, configuration and content, nothing else.
Tested against your own traffic and order peaks from last year plus the growth you are planning for, not a generic benchmark. The results are shared before the freeze, while there is still time to fix something.
Our engineers work US Central and Eastern time. For peak weekends we agree extended coverage and an escalation path in writing, so you are not waiting for a team that starts its day when yours is ending.
Anything that ships close to peak has a tested way back. Feature flags where it makes sense, so a change can be turned off without a deploy.
We design checkout so card data stays with your payment provider through tokenization or hosted fields, and we tell you when a requirement puts something back into PCI scope.
Last year's traffic and order data, a named decision maker during the freeze window, and access to the monitoring you already run.
A freeze calendar agreed in advance
Load testing against your real numbers
Coverage during your trading hours
A rollback plan for every release
Payments kept out of scope where possible
What we need from your side
How a retail build runs
What it takes to build, by system
Vendors answer this with 'it depends'. Here is what it depends on, by the kind of system, so you arrive at the first call knowing what to expect.
2-4 months
Number of systems, how clean the product and customer data is, and whether the platforms expose what you need.
3-5 months
Catalogue size, promotions and pricing rules, payment and tax providers, and how much of the design is new.
5-8 months
Channels and locations, sourcing and split rules, returns, and how much of the current process is undocumented.
4-8 months
Hardware you run, offline behaviour, number of store workflows, and the training the rollout needs.
4-6 months
Loyalty rules, the systems it reads from, payments, and how the account has to behave in store.
6-12 months
Catalogue and customer migration, integrations to rebuild, and how much can run in parallel before cutover.
Integration layer across your stack
Custom storefront or checkout work
Order management
Store or point of sale application
Customer app and loyalty
Replatforming

Three ways to work with us
Pick the model that fits how your team runs. Plenty of clients start with one and move to another as the roadmap grows.
Staff augmentation
Senior engineers added to your existing team, under your direction. Best when you have a technical lead and need capacity or a specific skill.
Dedicated development teams
A stable team that works only on your product, with a lead on our side. Best when you want a whole workstream owned without hiring a manager for it.
Software development outsourcing
A defined scope delivered end to end under our management, for a fixed price and date. Best when the scope is clear and you want one number and one date.
