What is Mini POS

Mini POS adds a retail register to Business Central. It keeps its own lightweight POS catalog (POS Items, POS Customers, POS Sales) that you can optionally map to your standard BC Items and Customers, so a store can start selling in minutes and still post real Sales Invoices. The main pieces:

• The POS Register — a full-screen, touch-first register with item tiles, barcode scanning, a cart, a native tender screen with split payments, and a status bar for shifts, parked sales, sales history, lock, and printing. See The POS Register.
• Payments — a configurable tender-method catalog (cash, card, on account, vouchers…), split tender and change handling, integrated card payments (Stripe Terminal, Datacap NETePay, QR/wallet pay), and dual pricing / surcharge support. See Tenders & Payments and Card Payments & EFT.
• Cash discipline — shifts with opening float and blind close, pay in/out and safe drops, No Sale audit, X/Z reports, and optional per-store/currency cash rounding. See Shifts & Cash Management.
• Real accounting — end-of-day consolidation posts genuine BC Sales Invoices (or Orders) through Sales-Post, with per-tender settlement into your G/L and bank accounts. An explicit, company-time-zone-aware Business Central Job Queue schedule can run the same canonical posting body automatically. See End of Day & Posting.
• Receipts without a hardware station — five print transports (WebUSB/WebSerial, LAN ePOS, PrintNode, BC Printer, browser), drawer kick, gift receipts. See Receipts & Printing.
• Weighed sales and kitchen output — weighted/price-embedded barcodes remain immediate scan paths; live scales use server-authoritative Web Serial capture. Category/item kitchen policies route independent ESC/POS, ZPL, or RDLC label copies after sale commit. See The POS Register and Kitchen labels.
• Governed loyalty foundation — company-scoped programs, rules, memberships, guarded lifecycle tables, administration pages, deterministic evaluators, durable Voucher reservation, atomic completion, frozen normal-receipt facts, and first-completion issue/Voucher accounting for Points, Visit/Stamps Value, Cashback, and Tiers. Exact-source multi-card refund authority and exact partial/repeated/final Points, Visit/Stamp, Cashback, and Tier returns are implemented, including signed return debt and immediate re-expiry of restored expired value. Task 13C also provides append-only reopen reversal and recompletion, open-sale reservation release, the internal completed-cancellation reversal boundary, EOD retry idempotency, and protected Item Rewards with exact stock/posting/return/cost identity. Durable accrual, redemption, restoration, reversal, adjustment, opening-liability, breakage, and reconciliation accounting, scheduled expiry, cashier UX, reports, and demo templates are implemented. Final release acceptance remains pending. See Customer 360 & Loyalty.

Everything behavioral ships as a Setup toggle or a per-store/per-terminal override — the full field reference is in Administration & Setup Reference. A back-office analytics hub, rebuilt role centers, and an operational report family (daily reconciliation, sales & tender detail, tax/VAT summary, returns, kitchen print audit) round out the picture.

Quick start

The install-to-first-sale path, in order (each step is detailed in Getting Started):

1. Install the app. Deployment adds the application and emits database-scoped telemetry; it creates no company operational data.
2. Run the wizard — Assisted Setup → "Set up Mini POS": company setup, store, terminal, number series, cash customer, tenders, barcode defaults, and optional demo data.
3. Load demo data (optional, recommended for evaluation) — a DEMO-prefixed store with terminals, categories, items with barcodes and variants, customers, PIN users, and sample sales.
4. Assign permission sets — BAA POS - User for cashiers, BAA POS - Admin for managers (both on top of a base BC license role).
5. Ring your first sale — open the POS Register, tap an item or scan a barcode, tap Tender, take cash, print the receipt.
6. Close the day — close the shift (count the drawer, X/Z report), then run End of Day to post consolidated invoices.
