The problem

Common minimarket problems MATE solves directly

These are real problems MATE solves for minimarkets with one or multiple branches

Inconsistent cash closes

Every cashier closes differently, and by the end of the day nobody knows where the shortfall went

With MATE: every register logs openings, transactions, and a cash count per shift. When the shift closes you see the overage or shortfall, and the audit log shows who performed each operation.
Uncoordinated branches

You have several branches and each one handles stock, prices, and users differently

With MATE: manage your branches from a single panel, with stock per branch and warehouse, and each user only accesses the branches assigned to them.
Outdated stock

You sell a product at the register but stock doesn't reflect it until hours later

With MATE: inventory updates with every sale, adjustment, and goods receipt, and a filter instantly shows which products are running low.
Complex invoicing

Issuing tax receipts and staying compliant with ARCA eats up your operating time

With MATE: integrate ARCA to issue receipts right inside the sales flow without leaving the system.
Receipts never sent

Customers ask for a ticket or invoice on WhatsApp and your team sends it late or never

With MATE: send the receipt via WhatsApp or email from the sale itself, without chasing the customer later.
Guesswork purchasing

You order from suppliers without really knowing what you're short on or overstocked with

With MATE: the system suggests what to restock, grouped by supplier; you build the purchase order and log the goods receipt, which adds to stock.
How it helps you

What you'll be able to do with MATE from day one

This isn't a technical checklist — these are everyday bottlenecks at a minimarket

Multi-register with per-shift cash counts

Manage multiple registers in parallel, with openings, closes, and cash counts per cashier. Everything is logged with an auditable history.

Example: at closing time you spot a discrepancy on Register 2: you open that session's detail to see its transactions and who ran each one.

Multiple branches, one panel

Control each branch with its own users, registers, and stock, and as the administrator you see all of them from the same panel.

Example: check the stock at each branch and warehouse to decide where to restock, without waiting for someone to send you a spreadsheet.

Receipts via WhatsApp

Send tickets and receipts to the customer via WhatsApp straight from the sale, cutting down on counter waits and repeat questions.

Example: the customer pays, walks out, and already has their receipt on their phone with the exact time, detail, and amount.

ARCA integration

Electronic invoicing built into the point of sale to stay compliant, with no duplicate work between the register and external systems.

Example: from the confirmed sale you issue the invoice (A, B, C, or M) and it stays linked to that register transaction.

Purchasing and restocking

MATE suggests what to restock based on low-stock products, grouped by supplier. You build the purchase order and log the goods receipt.

Example: on Monday you review the suggestions, generate the order for the distributor, and when the truck arrives you check what was received and stock updates.

Stock and product management

Catalog products with barcodes, categories, and prices; control inflows, outflows, and adjustments, and filter low-stock products to avoid empty shelves.

Example: before opening you filter the low-stock products and already know what to restock.

User and permission management

Define roles by position: cashier, manager, or administrator. Each user sees and operates only what applies to them.

Example: the cashier can sell and close their shift, while the administrator handles stock adjustments, users, and reports.

Business reports

Sales, product, inventory, purchasing, and register reports, with comparison against the previous period and a breakdown by payment method.

Example: at month's end you see how much you sold versus the previous month, which products sold most, and which barely moved.

Audit log and backup

Sales, stock adjustments, and changes to users and branches are recorded in an audit log with user and date. And you can download a backup of your data in Excel whenever you want.

Example: a stock adjustment shows up that nobody remembers: you look it up in the audit log and see who made it and when.
Use cases

This is how MATE changes your business's week

Three everyday situations at a counter-service store

Monday 8:30 AM

You open the store already knowing what to restock, what arrived, and what's critical

Before, you started the day guessing shortages between notebooks and spreadsheets. Now you open MATE and see the low-stock products, the purchase orders waiting to be received, and the best sellers.

  • List of low-stock products
  • Summary of the previous day's register sessions
  • Overage or shortfall of each close at a glance
  • Restocking suggestions grouped by supplier
Opening · Monday 8:30 AM
Cream cheese 4kg Low stock
French bread 18u Low stock
Register 2 · Diff. $2,450 Review
Centro Branch Open
Terminal Branch Open
Tuesday 3:00 PM

You sell at the counter and the receipt goes out via ARCA and WhatsApp in the same step

Before, you'd make the sale one way, the invoice another, and then track down the customer to send the ticket. With MATE it all happens in the same register flow, with no double entry or delays.

  • Sale logged per register with payment method
  • Tax receipt issued in ARCA right from the transaction
  • Automatic stock deduction per item sold
  • Ticket sent via WhatsApp from the same screen
Sale · Register 1

Friday 5:30 PM

You close the week knowing how much you sold, what's moving, and what isn't

Before, the weekly close depended on loose spreadsheets and manual tallies. Today you open the reports and see sales versus the previous week, cash discrepancies, best sellers, and slow movers.

  • Period sales and comparison with the previous one
  • Cash discrepancies by session and cashier
  • Best sellers and slow movers
  • Low-stock products to restock

Retail scenarios

MATE adapts to every minimarket format

MATE's core combines multi-register, multi-branch, stock, users, and integrated invoicing for different minimarket formats. Here's where it delivers the most value:

Minimarkets and convenience stores

Daily operations with one or several registers, shelf control, restocking, and per-shift closes with no parallel spreadsheets.

Example: a neighborhood minimarket controls opening/closing per cashier, stock by branch, and sends receipts via WhatsApp from the register.

Small supermarkets

Lots of products, several payment methods, and shortage control so you don't lose sales at peak hours.

Example: a small supermarket with two registers monitors sales per shift, spots discrepancies at closing, and plans restocking with real data.

Delis

Fast-moving products that can't run out and a busy register. Ideal for keeping checkout and restocking in order day to day.

Example: a deli tracks sales per register, checks which products sell most, and restocks fast movers on time.

Bakeries

Busy counter sales at peak hours and one register per shift.

Example: a bakery opens a register per shift, checks the overage or shortfall at closing, and sees which products sold most that week.

Poultry shops

Fast counter sales with traceability by register and by operator.

Example: a poultry shop loads its combos as products, sells fast at the counter, and at closing knows what each cashier sold.

Butcher shops

Track sales per product, turnover, and supplier purchases so you don't overstock fresh products.

Example: a butcher shop checks which cuts sell most, spots slow movers, and adjusts orders to the supplier.

Corner stores and kiosks

Neighborhood businesses with high turnover and small tickets that need fine-grained control of registers, prices, and stock.

Example: a neighborhood kiosk logs sales per register, checks low-stock products, and restocks key items before running out.
