Product guide

Every module, explained — so you know what you’re buying.

The homepage shows the big picture. This page is the operator’s manual: how the till works, how tax is calculated, how stock stays honest, and how your team stays accountable.

Built for real counters

Different shops. Same backbone.

Provisions & mini-marts

Fast barcode checkout, MoMo, low-stock alerts on rice oil soap — stop “missing” crates before month-end.

Pharmacies & wholesalers

Quotes and invoices with PDF share, customer phones on WhatsApp, wholesale prices when you need them.

Multi-branch retail

Branch assignment, role permissions, shared catalog rules, and day-end numbers owners can trust.

Modules

Under the hood of your shop OS.

Point of sale

A keyboard-first web terminal built for speed. Scan barcodes, hold carts during a rush, settle with cash or MoMo, and preview the GRA tax breakdown before you print.

  • Barcode search with hotkeys
  • Hold / recall carts
  • Cash denomination & change calculator
  • Receipt preview + print / WhatsApp / email

Tax engine

Local tax presets per market. Ghana shops can run Standard statutory levies or VAT Flat Rate — with transparent line-level tax on every invoice and sale.

  • GRA standard (NHIL + GETFund on base, then VAT)
  • Configurable flat-rate schemes
  • Tax-exempt staples
  • Monthly tax-style reports

Inventory & catalog

Products, categories, batches, and reorder hints. Configure oversell rules, whether cost shows on POS, and default alert quantities — then import catalogs from Excel.

  • Low-stock dashboard alerts
  • Per-tenant stock policies
  • Bulk Excel import
  • Branch-aware catalog

Invoices & quotes

Create professional quotes, convert to invoices, record payments, and share a PDF link by email or WhatsApp — not only thermal print.

  • Quote → invoice conversion
  • Email with PDF link
  • WhatsApp share with totals
  • Payment history on the document

Printers & scanners

Hardware settings live in System Settings. Pair thermal printers, set paper width, auto-print after payment, and tune barcode wedge or camera scanning.

  • 58mm / 80mm thermal
  • Auto-print & drawer kick
  • Prefix/suffix strip for wedges
  • Beep on successful scan

Team & permissions

Invite cashiers, managers, and admins. Customize the permission matrix so only the right people touch tax, settings, or inventory adjustments.

  • Admin / Manager / Cashier
  • Tenant permission matrix
  • Branch assignment
  • PIN unlock for the till

Mobile apps

Flutter apps for Android and iOS share the same API as the web terminal — ideal for roaming attendants, market stalls, and pop-up counters.

  • Camera barcode scanning
  • Bluetooth thermal printing
  • Offline sell & sync
  • Shared tax & MoMo rules

Analytics & exports

Live revenue, COGS, tax collected, and top products. Export PDF or Excel for your accountant — without rebuilding the books at month-end.

  • Live KPI dashboard
  • PDF & Excel exports
  • Top products & tax collected
  • Shift-friendly day summaries
