Description
TallySeller | Third-Party eBay-Compatible Profit Tracker and Analytics SaaS | Laravel and Flutter
TallySeller | Third-Party eBay-Compatible Profit Tracker and Analytics SaaS | Laravel and Flutter is a production-ready eBay profit tracker and sales analytics platform that connects to a live eBay seller account in read-only mode and does the one thing generic spreadsheets can’t: it pulls every order from the eBay Fulfillment API and every real eBay fee and refund from the eBay Finances API, then matches each sale to your inventory cost to calculate genuine net profit and margin per sale.
TallySeller — Key Features
At A Glance
- Real eBay data, read-only — orders from the eBay Fulfillment API and every fee and refund from the eBay Finances API, synced automatically every 15 minutes plus on-demand “Sync now”
- True profit per sale — sale price − inventory cost − real eBay fees − shipping − refunds, with both average and FIFO COGS frozen at sale time
- Two costing methods side by side — Average (moving average pool) and FIFO (lot-based) with a switch that recomputes profit everywhere, on web and mobile
- Native Flutter app included — Android & iOS with full source code, English & Arabic (RTL), secure Sanctum token auth
- Multi-tenant SaaS engine — workspaces, 4 seeded plans, free trials, monthly/yearly billing, coupons, taxes, currencies and usage quotas
- 6 online payment gateways + offline — Stripe & PayPal with recurring subscriptions, Razorpay, Paystack, Flutterwave, MercadoPago and bank transfer with admin approval
- Team management — invite by email with Manager (write) and Viewer (read-only) roles and plan seat limits
- Multiple eBay accounts per workspace with activate / label / disconnect management, capped by plan
- Exports — orders CSV (both cost views) and shipping XLSX for label workflows
- Web installer + demo data seeder, branded transactional emails, license validator, and full source code for everything
Seller Dashboard & Analytics (Web)
- KPI cards for revenue, units sold, cost, net profit, margin and refunds — switchable between Average and FIFO cost views
- Daily net-profit chart for the week, recent sales and refunds at a glance, and whole-page filtering by SKU
- Reports — total profit, units sold, matched SKUs, average profit per day, best day, profit-over-time chart and a best-sellers ranking
- Quota-aware syncing with a usage banner when a workspace nears its plan limit
- Backfills — re-import missed orders for 1/2/7 days from the UI, or up to 90 days via CLI
Inventory & Costing
- Add stock by SKU with quantity and total cost paid — duplicate SKU automatically becomes a restock
- Average costing — every restock blends into a moving average cost per unit
- FIFO lots — each restock is a lot; sales consume the oldest lot first, with a full lot browser per item
- Frozen costs — cost per unit is snapshotted at sale time, so later restocks never rewrite profit history
- Item detail page — remaining quantity, stock value, FIFO lots, full restock history and monthly restock table
- Low-stock badges when remaining quantity falls to or below a configurable threshold
- SKU lookup API for quick barcode / scanner integrations
Orders, Fees & Refunds
- Automatic order sync every 15 minutes via the eBay Fulfillment API, with multi-line orders grouped by base order ID
- Real eBay fees per order from the Finances API — including automatic signed-request handling for UK/EU sellers
- Finance breakdown per order — sale price, fee lines, shipping, refunds, COGS (average + FIFO) and net profit in both views
- Refund handling that updates order status (paid → partial → refunded) and reverses stock correctly
- Manual unit-cost override per order and a per-order finance refresh button
- Filters — status (paid / refunded / partial / unmatched), search, date range, eBay account and cost view; export the filtered list to CSV
Shipping
- Packing-friendly shipping list — product, quantity, buyer and address, with eBay reference tokens stripped
- XLSX export of the filtered list for label workflows
- Copy-ready buyer addresses also available in the mobile app
Flutter Mobile App (Android & iOS)
- Five-tab shell — Overview, Orders, Inventory, Reports and Settings, with pull-to-refresh and a polished light theme
- Overview — KPI grid, profit line chart, recent sales, low-stock items, plan usage card, Sync now with 1 / 2 / 7-day re-import
- Orders — search, status chips, Average / FIFO toggle and full finance breakdown per order
- Inventory — search, add stock & restock with live cost-per-unit, FIFO lots, duplicate SKU = automatic restock
- Reports — total profit, revenue, margin, daily bar chart and best-sellers ranking
- Settings — one-tap eBay connection (read-only OAuth handoff in the system browser), plan & billing with hosted checkout, team management, shipping addresses with one-tap copy, English / العربية switch
- Server URL field on the login screen — buyers point the app at their own domain in seconds; per-device Sanctum tokens in the secure keystore/keychain, logout revokes only that device
