In short
Multi-location retail software from Athyrium Studio combines a POS that keeps selling offline, consolidated real-time inventory, store-to-store transfers, shift-based register closings, per-store dashboards and franchise royalty reporting. It connects to your accounting, payment processor and online store, and it handles e-invoicing rules in Colombia, Mexico and Spain when you sell there.
What breaks when you add locations
- 01
When the internet drops at one store, checkout stops and the line goes out the door.
- 02
One location runs out of a product while another has too much, and nobody sees it in time.
- 03
Register closings do not balance, and we find the gap days later.
- 04
Franchisees send sales in different spreadsheets, so royalty reports are always late.
What we build for retail chains
Consolidated inventory and transfers
Stock for every store and warehouse in one view, transfers with receiving confirmation, low-stock alerts and cycle counts.
Shift-based register closing
Opening and closing by cashier, counts by payment method and every variance logged with who, when and which store.
Per-store dashboards
Sales, margins, best sellers and turnover by store, comparable side by side with the same cutoff hours.
Franchise management
Sales by franchisee, royalty and marketing fund calculations, and a catalog and promotions controlled from headquarters.
Online and delivery orders
Orders from your online store and delivery apps land in the right store's queue and draw from the same inventory.

Invoicing and payment rules we plan for
Each store issues receipts and keeps customer data under different rules depending on the country, and we design the POS around these rules from the architecture up.
- PCI DSS v4.0.1International
Security standard for card payments at your registers and in your online store.
- Resolución 000165 de 2023Colombia
DIAN rule for the electronic POS receipt (documento equivalente electrónico tiquete POS) issued by stores in Colombia.
- CFDI 4.0Mexico
Current version of Mexico's SAT electronic invoice, including the global invoice for sales to the general public.
- VERI*FACTUSpain
Royal Decree 1007/2023 requirements for invoicing systems in Spain, mandatory for companies from January 1, 2027 under RDL 15/2025.
- Ley 1581 de 2012Colombia
Colombia's personal data law for customer and loyalty program records captured at checkout.
Questions retail operators ask
Does the POS keep working when a store goes offline?
Yes. Each register stores sales locally and keeps checking customers out, then syncs sales and inventory with headquarters once the connection returns, without creating duplicate receipts. Where e-invoicing applies, documents are sent following the local contingency rules, and the dashboard shows which stores still have pending syncs.
Can you work with the payment terminals and processor we already have?
In most cases, yes. We integrate with processors and terminals that offer an API or SDK, such as Stripe Terminal or Square, and with local acquirers in Latin America. Keeping card data inside the terminal and the processor also keeps most of your POS out of PCI DSS scope.
Can it handle franchise royalties and marketing fund contributions?
Yes. Sales from each franchisee flow into the same system, royalties and marketing fund contributions are calculated with the rules in your franchise agreements, and each franchisee gets a statement they can check against their own sales. Headquarters controls the catalog and promotions, while franchisees run the daily operation.
Do you support stores in Mexico, Colombia and Spain?
Yes. We work remotely with chains in the US, Mexico, Colombia and Spain. The POS uses one inventory and reporting core with a document module per country: electronic POS receipts with the DIAN in Colombia, CFDI 4.0 through a PAC in Mexico and VERI*FACTU-ready invoicing in Spain.
How long does it take to roll out to all our locations?
It depends on scope and the number of stores, so we start with a phased plan after the first meeting. Usually one pilot store goes live first, your team adjusts the workflow with real customers, and then the remaining locations follow in waves, each with its own opening inventory count.
Tell us how many locations you run
We will walk through how you sell, move stock and close registers at each location. We sign an NDA before you share sales data, inventory or franchise agreements.
