Lytning glossary (plain language)
Use this page when you come across a Lyt-ning term you don't recognise — and you want the plain-language meaning without leaving the Wiki.
Goal
You need to find what a Lyt-ning term means in plain language, without reading engineering documents.
Where this happens
This glossary applies across every Lyt-ning app — till apps, Core App (back office), and Lytning Analytics.
- At the till: the same terms appear on till screens (for example End User Shift, Refund, GRV).
- In the back office (Core App): the same terms appear in the sidebar (for example Cashups, Specials, Stock Templates).
- In Lytning Analytics: report names (for example Cash Flow Statement, Income Statement) live in the analytics app.
Prerequisites
None — use this as a reference whenever you see a term you don't recognise.
Steps — alphabetical, plain-language entries
B
BAPI — SAP's standard application interface. Lyt-ning uses it to post totals to your SAP ledger. Configured under Add-ons & Integrations — SAP appears there when the add-on is enabled for your franchise.
Back office — The Core App. The web app supervisors and franchise admins use. Same thing.
Batch / batch code — A group of items that share an expiry or batch number. Pharmacy and fresh-food stock use this. The till screen asks for it when needed; ask your supervisor if you are unsure which items need it.
C
Cash-up / cashup — End-of-day reconciliation of cash, card and other payments against the day's sales. Done in the Core App's Till Management → Store Cashups.
Closing the shift — Same as End User Shift — the cashier closes their till at end of shift.
Core App — The Lytning back office. Sign in at https://lytning-core.pages.dev/ (or your store URL).
Credit note — A fiscal reversal of a Smart Invoice — used when a sale is refunded in ZRA-mode. Issued by the Smart Invoice integration automatically.
CRV — Cash Received Voucher — a record of cash received into the store. Your franchise may use a different name for the same document; ask your supervisor.
D
Daily operations — The Core App's main sidebar group for routine day-to-day tasks: sales, stock, customers, finance, suppliers, specials, loyalty, reports.
Demo store — A pre-populated store used for training and demos. Don't enter real customer data here.
DPV — Deposit Voucher — a record of cash deposited at the bank. Your franchise may use a different name for the same document; ask your supervisor.
E
Edit Float — The opening cash in the till drawer before the shift starts. Recorded in the Core App at Till Management → Edit Float.
End User Shift — The till's "close shift" button. Used at end of shift on the till home screen.
Expenses — Out-of-pocket spending recorded in the Core App. Your franchise admin will show you the exact Expenses screen path on your store's Core App — it is not documented as a single named screen in the Wiki.
F
Franchise — The business entity that owns one or more stores. You sign in to a franchise once, then pick a store from your assigned list.
Float — Same as Edit Float — the opening cash in the till.
G
GRV — Goods Received Voucher — the record of stock received from a supplier. Recorded in the Core App or the till.
I
Invoice — A fiscal receipt printed after a sale, used in ZRA Smart Invoice.
L
Loyalty — The till-app's points program (separate from the Lyt-ning Loyalty Setup add-on).
Lytning Analytics — The reports app at analytics.pos.co.zm. Opens from the Core App via single-sign-on — you don't open it directly.
P
PIN — A numeric password used at the till. Different from the Core App username/password. Set per employee under Finance & Admin → HR Management → Employee Security.
Procurement / Purchase order — An order sent to a supplier for stock. In the Lytning Core App, view via Stock Management.
R
Refund — A reversal of a sale. Done on the till (Refund screen) and recorded in the back office. In ZRA-mode, Smart Invoice issues a credit note automatically.
S
SAGE / SAGE 300 / SAP — Accounting systems Lyt-ning can post to. Each is configured in the Core App under Add-ons & Integrations (SAGE / SAGE 300 / SAP sit there).
Safe — A physical cash box at the store. Your franchise admin will show you how to view the safe in the Core App — the Wiki does not name a single screen.
Shift — One cashier's working period, from open to close.
Smart Invoice — The ZRA Smart Invoice integration. Auto-submits fiscal receipts to ZRA. Configured under System & Settings → Till & Payments → Smart Invoicing.
Specials — Discounts / multi-buy / combo rules. Set up in Sales Management → Active Specials (top-level sidebar group).
Store — One physical store. Each store has its own database and TPIN.
Subscription — The active license for the franchise. Expired subscriptions block new logins. Renew at System & Settings → Billing → Subscription & Accounts.
Supplier — A vendor that provides stock to the store. Created in Supplier Management (top-level sidebar group).
Support ticket — A request sent to the Lyt-ning support team. Created in the Support drawer (till) or Support & Documentation (back office).
T
TPIN — Tax Payer Identification Number. The store's unique tax ID.
Till — The counter device — tablet or terminal. Runs the POS app.
Tilly app — Same as till app — the counter app.
U
User — A person authorised to use Lyt-ning. Created in Finance & Admin → HR Management → Create Employee; permissions are set in Employee Security.
V
Void — A cancellation of a transaction. Different from a refund (no cash moves, just the record disappears). Done on the till.
Expected result
You can read any Lyt-ning term without leaving the Wiki.
Edge cases
- A term here is wrong or missing — let Support know via the Support drawer (till) or Support & Documentation (back office).
- You need a deep-technical definition — that's the engineering side and is not part of this Wiki.
- The same word means something different in your industry (for example "shift" in a restaurant context) — the definition here is the Lyt-ning meaning.
