Overview

GadgetOS is the retail-management system a Bangladeshi phone, laptop and electronics shop runs on — point of sale, stock by IMEI and serial number, a warranty and repair desk, suppliers, and VAT-compliant receipts. This connector gives the owner and staff of one shop a plain-language way into their own live records. Ask what sold this month and get the real figure. Ask what is running out and get the items below their reorder level with a suggested quantity. Ask about one IMEI and get that exact handset: in stock or sold, its cost and its price, when it arrived and when it left, and the warranty left on it. Ask what is on the repair desk and get every claim with its status, customer, device, days open and estimate. Ask whether a customer's phone is still under warranty and get the determination from the sale date — or, where no warranty period was ever recorded, that fact stated plainly instead of a guess. With the owner's opt-in it also writes: ring up a sale — a real invoice with a receipt number that takes the payment and moves stock (the assistant confirms the devices and the amount with the owner first; voiding or refunding a sale stays in the app, behind a manager PIN); open or close a branch's cash drawer against the cash counted; create a device, change a price, a rack location or a reorder level; add a product photo through a single-use upload link, or arrange and remove product photos; receive stock or one serialized unit; log an expense; add a supplier; raise a draft purchase order; record a customer's payment against what they already owe; book a device in for repair; and move a claim along to inspecting, estimate pending, approved, repairing, ready or delivered. Only two actions can reach anyone outside the shop, and only if the shop has switched SMS on (it is off by default): a sale that names a customer can send that customer one receipt SMS, and a claim moved to ready or delivered can send the claim's customer one SMS. No tool accepts a phone number or message text from the chat. It searches a shared reference catalog of phones, laptops and accessories, so adding a product inherits the right brand, category, specifications and official image rather than starting from a blank row. Everything is scoped to the single shop the signed-in user belongs to. There is no parameter on any tool that could reach another business's data. Rejecting or refunding a warranty claim needs a manager PIN, and there is no tool for it — that stays in the app on purpose. Amounts are in Bangladeshi Taka, held as integer paisa. Dates are Asia/Dhaka. Bangla and English both work.

Tools

advance_warranty_claim

ChatGPT
Moves an existing warranty claim to a later status, with the technician's diagnosis or a repair estimate. delivered closes it for good; ready and delivered text the customer when warranty SMS is on. rejected and refunded need a manager PIN in the app.

close_shift

ChatGPT
Ends a branch's open cash-drawer session against the cash counted out and records the variance. A closed drawer cannot be reopened, and a count off by more than Tk 1 is refused — that close needs a manager.

create_product

ChatGPT
Writes one new product row in the business's own catalog. Prices are in paisa (minor units).

create_product_image_upload

ChatGPT
Mints one single-use browser link, valid 30 minutes, that attaches a single image of up to 5 MB as a product’s main photo. An earlier photo from this same flow is deleted; one the owner added in the app moves to position 2 and is kept. Nothing is written until that file arrives.

create_purchase_order

ChatGPT
Writes a DRAFT purchase order and its lines. It is never transmitted to the supplier and commits no money; sending stays behind maker-checker approval.

create_sale

ChatGPT
Writes one sale: invoice and receipt number, stock decrement, payment; the business resolves lot and price. May SMS the customer a receipt (if on); on khata, alerts the owner's linked Telegram (default on) and SMSes the customer (if on). Voidable 24 h via void_sale; no refunds.

create_supplier

ChatGPT
Writes one new supplier record, including payment terms and any opening balance.

get_cash_position

ChatGPT
Money actually received over a date range, split by payment method — the daily-close figure.

get_cashier_performance

ChatGPT
Per-cashier sale count, revenue, discount given and voids over a date range.

get_customer_dues

ChatGPT
The receivables board: customers who owe the shop, biggest first, with the exact shop-wide total owed. With q, the matching customers and what each owes.

get_dead_stock

ChatGPT
Products with no sales in the lookback window, and the capital tied up in each one.

get_expense_summary

ChatGPT
Operating spend over a date range, totalled and broken down by expense category.

get_inventory_valuation

ChatGPT
Current stock value at cost and at retail, with per-category subtotals and a shop-wide total.

get_inventory_velocity

ChatGPT
Sell-through rate per product: units sold per day, and estimated days of stock remaining at that rate.

get_low_stock_items

ChatGPT
Products at or below their reorder level, with current stock on hand and the reorder point.

get_product_image_upload

ChatGPT
The most recent photo-upload link’s state for one product — awaiting_upload, uploaded, failed (sent but not stored, so nothing changed), expired or never_requested — plus the shop’s own photos in order with their photo_id, and whether it shows a shared-catalog picture instead.

get_profit_summary

ChatGPT
Gross profit (revenue minus cost of goods sold) over a date range. With a group_by dimension it returns the same figures broken down by that dimension instead of a single total.

get_reorder_suggestions

ChatGPT
Suggested purchase quantities per product, derived from recent sales velocity, current stock and reorder level.

get_sale

ChatGPT
One invoice in full: header totals, payment method and every line item on it.

get_sales_summary

ChatGPT
Completed-sale count and revenue totals (subtotal, discount, VAT, total) for a date range, for the signed-in business's own data only. Voided, refunded and pending sales are excluded.

get_sales_trend

ChatGPT
Revenue and sale count bucketed over time (by day, week or month) across a date range.

get_shift_status

ChatGPT
Whether a cash drawer (POS shift) is open at a branch, how long, who opened it, and the cash the close-out would expect in it: float + cash sales + khata + deposits − approved cash drops − expenses paid from the till. A drawer open for days was abandoned, not worked.

get_shop_profile

ChatGPT
The signed-in business's own storefront details: name, address, working hours, contact channels, BIN/TIN, storefront URL, theme and plan.

get_suppliers

ChatGPT
The supplier directory, and — for owner, admin, regional-manager and pharmacist callers — accounts payable per supplier, shop-wide totals and aging buckets; other roles receive the directory alone. Also the source of a supplier_id for a purchase order.

get_top_products

ChatGPT
Best-selling items over a date range, ranked by quantity sold or by revenue, capped at 50 rows.

get_warranty_claims

ChatGPT
Warranty and RMA claims: the claim board, one claim's detail with its audited event timeline, view=summary for desk-health aggregates, or view=unit for a serial/IMEI coverage check.

get_wastage

ChatGPT
Stock written off over the last N days (max 366), in units: totals by kind (damaged, and other wastage such as stolen or lost), entry counts, and the most-wasted products. No money value. Items written off by weight add entries but no units.

hand_over_warranty_claim

ChatGPT
Records that the customer collected the device and closes the warranty claim for good: no reopen, advance or note after it.

list_products

ChatGPT
Products in the business's own catalog, optionally narrowed by free-text q, barcode or sku, with the matching total count.

list_sales

ChatGPT
Recent sales newest-first, header rows only, cursor-paginated, with voided ones flagged. get_sale with a sale_id gives one sale line by line.

log_expense

ChatGPT
Writes one operating-expense row: amount in paisa, category, date and an optional note.

logout

ChatGPT
Revokes EVERY assistant connection the signed-in operator holds to this business, not only the calling one: any other ChatGPT, Claude or connected app they signed in from stops too, on every brand. Other operators and counter devices are unaffected.

lookup_customer

ChatGPT
One customer's profile, khata (on-account) balance, loyalty position, lifetime spend, recent invoices and usual items.

open_shift

ChatGPT
Starts a branch's cash-drawer session with the cash counted into it; every later variance is measured against that float. One drawer per branch: a branch with one already open is refused.

open_warranty_claim

ChatGPT
Books a device in as a NEW warranty claim by serial or IMEI, with the fault in the customer's words, adding the customer by phone if new. A device with a claim already open is refused. Returns the new claim number.

receive_stock

ChatGPT
Writes a new pooled stock batch: quantity, unit cost, and optional batch number and expiry date. The stock becomes sellable immediately.

receive_unit

ChatGPT
Writes one serialized unit into stock, identified by its IMEI or serial number.

receive_warranty_repaired

ChatGPT
Records that the supplier repaired the customer's OWN device and returned it with the same serial or IMEI; a different device is refused. A new unit in its place is receive_warranty_replacement instead.

receive_warranty_replacement

ChatGPT
Records the DIFFERENT unit a supplier sent in place of a claimed device, by its serial or IMEI, and whether its warranty continues or starts fresh. The same device, repaired, is receive_warranty_repaired instead.

receive_warranty_supplier_restock

ChatGPT
Puts the supplier's unit for a warranty claim onto the shop's shelf as sellable stock — the tail of a claim already settled from the shop's own stock — identified by serial or IMEI.

record_customer_payment

ChatGPT
Records money a customer handed over, against their khata (on-account) balance, and reduces what they owe. It moves no money at any payment gateway. Paying past zero is refused unless allow_advance is set. Only cash completes; other tenders need a reference it cannot take.

remove_product_photo

ChatGPT
Removes one photo from a MODEL's gallery and permanently deletes its file, addressed by photo_id — never an individual serialized unit's photo.

reorder_product_photos

ChatGPT
Rewrites the order of a MODEL's photos, main photo first, listing every current photo_id once — never an individual serialized unit's photos. A gallery edited elsewhere is reported, not overwritten.

search_catalog

ChatGPT
Searches the SHARED reference catalog, which is not the business's own stock, so a new product can be linked to a canonical entry.

search_help

ChatGPT
The published in-app user manual for this business's vertical — how the app works and how to do things in it. Product documentation only: no sales, stock, customer or staff data. A slug returns one article in full, in English and Bangla; otherwise matching titles.

send_warranty_claim_to_supplier

ChatGPT
Records that a warranty claim's device went to a supplier for repair or replacement: the supplier, its RMA number, and when the device is due back.

set_primary_product_photo

ChatGPT
Makes one of a MODEL's existing photos the main one, addressed by the photo_id the status tool lists — never an individual serialized unit's photo. No file is uploaded or deleted.

update_product

ChatGPT
Overwrites fields of an EXISTING product (name, prices, missing cost, location, reorder level, status, listing, barcode, category, MRP, description, key features, FAQ, specifications). Listed products and prices are public: storefront, marketplace if joined, linked Meta catalog.

void_sale

ChatGPT
Cancels one sale within 24 hours of it being rung up: the stock returns to its branch, the payments are reversed and any amount on a khata is credited back. The invoice number is kept. Older sales need a refund, which is not on this server.
