1. First-time setup

Do this once per business, not every session.

• Click ⬇ Load Items & Customers — fetches every inventory item, non-inventory item, customer, and bank/cash account, and calculates current stock from your transaction history.
• Open ⚙ Setup. If no customer with code 999 or named "POS" exists, click Create Default "POS" Customer. Walk-in sales post against this customer; the person's name/phone (if typed) is saved in the invoice description. The Setup screen also explains how the POS tells cash from bank accounts.
• Toggle 🌙/☀️ for light/dark mode.

2. Making a sale

Add items three ways: scan/type a barcode or code and press Enter; type to search and pick from the dropdown; or tap a tile in the Quick Add panel (Inventory / Non-Inventory tabs). An unrecognized code prompts you to create the item on the spot.

Edit the cart: change Qty, Price (this sale only), or type a line Total to back-calculate Qty. Remove a line with ×, or Clear the cart.

Pick a customer (or leave it on the walk-in default), choose a payment method (cash accounts listed first), optionally type a walk-in name/phone, then click Complete Sale. A reference (POS-YYMMDD-HHMMSS) is generated automatically.

3. The receipt screen

• 🖨 Print — 80mm thermal layout.
• 📄 Save as PDF — a real PDF file, generated in-browser.
• 💳 Apply Credit — apply a customer's existing credit balance toward this invoice.
• 💰 Record Payment — a multi-line form: type Tendered and Amount + Change compute automatically (Amount capped at what's due). Add lines to split across methods. Set the Receipt Date if it isn't today. Each line posts as its own real Receipt. When cash is tendered, TENDERED PAYMENT and CHANGE are printed under the TOTAL on the receipt, and the tendered/change figures are saved into the Receipt's Description in Manager so the record persists.

4. Day Register

Click 🗄 Register. A live, read-only view of one day — every figure is computed from real Manager transactions each time you open or refresh it.

• Sales Invoiced, Cash Collected, Returns, and (if any) Bank Receipts and Cash Refunds Paid Out.
• Net Cash Movement = cash collected − cash refunds for the day. Figures are selected by each Receipt's own date and count only cash accounts; bank receipts are shown separately and excluded from the drawer figure. A later instalment against an older invoice therefore appears on the day the receipt was posted.
• A card per Sales Invoice (Total / Received / Due, Items drill-down, Receipts breakdown, and Receipt / ✎ Edit / ↩ Return / 💳 Adjust actions). The Receipt form has an editable date.
• Receipts Posted This Day and Payments / Refunds Posted This Day — itemized lists (ref, customer, account with a cash/bank tag, amount) so every cash figure is traceable.

Change the date with the picker, ↻ Refresh to re-pull, or 🖨 Print Day Summary — which uses the exact same calculation as the on-screen register.

5. Sales History

Click 🕘 History to search across all invoices by date range and/or ref/customer text (press Enter or click Filter). Same cards and actions as the Register. If more than 500 match, narrow the range. ↻ Refresh re-fetches from Manager.

6. Sales Analysis

Click 📈 Analysis, pick a range, and get invoice count, quantity sold, average sale value, total revenue, top 10 items by revenue and by quantity, and a day-by-day breakdown — all computed in your browser.

7. Returns and credit balances

To return goods: use ↩ Returns search, or the ↩ Return button on any invoice card. Enter the quantity per line (can't exceed what's un-returned), confirm date/reference, and post — this creates a real Credit Note.

When Receipts + Returns exceed what was owed, the invoice shows a Credit balance. Click 💳 Adjust to either Refund to Customer (a real Payment from a chosen account) or Apply to Another Invoice (a balanced Journal Entry).

8. Editing an invoice

Click ✎ next to any invoice reference to change its Reference, Issue Date, existing line Qty/Price, remove lines, or add a brand-new line. Click Save Changes to write back. Note: editing a paid invoice's total does not adjust Receipts already recorded — check those separately.

9. Before you rely on this in production

• Accounts Receivable resolution. The extension resolves the AR control account (customer's own → existing receipts → the flagged AR account). There is no hardcoded fallback: if it can't be resolved, the transaction is stopped with an error rather than posting to a guessed account. To fix that, post one transaction manually in Manager.io first — open a Sales Invoice and use its Copy to → New Receipt button — which records the correct Accounts Receivable account; the extension then reuses that account for subsequent transactions.
• Return-quantity tracking assumes Credit Notes made outside this extension also set the invoice reference; if not, "already returned" may undercount for those.
• Credit/Due nets Receipts, Credit Notes, Journal Entries, and refund Payments read live from Manager; money moved some other way won't show.
• Stock quantities are computed from transaction history — a strong indicator, not a guaranteed audit figure.
• Non-Latin names in PDF receipts — Urdu/Arabic (and other non-Latin) names may not render in the generated PDF and can come out blank or as isolated, unjoined characters. Treat this as a known limitation and check such names on the printed/thermal receipt instead.
