Two ways to sell

Built around how you actually sell.

Rotonda adapts to your business model. Pick the path that sounds like you — the app shapes itself to fit.

Path A

Products & Inventory

This is you if… you sell the same products over and over and need to track stock.
  • Product catalog & barcodes — scan to find, sell and restock.
  • Live stock tracking — quantities update with every sale.
  • Purchase & sales invoices — in and out, on one ledger.
  • Inventory count sessions — reconcile without the headache.
Path B

Unique & Serialized Items

This is you if… every item is one-of-a-kind — electronics, jewelry, used goods, rentals.
  • Track each item individually — with your own custom fields.
  • Serial numbers — every unit identified and searchable.
  • Full status history — in stock, sold, returned, rented.
  • Serialized invoice entry — sell the exact unit, not just a SKU.
The signature feature

From zero to invoice in seconds.

The fastest mobile invoice creation on the market. One screen: a collapsible camera up top, a live item list below, and a running total that never leaves your sight. No modals. No page-hopping. Four ways to add an item — each in a single tap.

Inventory, handled

Inventory counts that actually get done.

Counting stock is miserable in most apps. Rotonda turns it into a fast, structured workflow you can finish in one sitting — and it posts the results to your books automatically.

Full or partial counts

Count everything, or just selected products. Filter by All / Never Counted / Counted — you never lose your place.

Tap, type, next

Tap a product, punch the quantity on the number pad, move on. Built for speed on a phone.

Live discrepancy detection

Mismatches highlight in red the moment they appear — no surprises at the end.

Finalize → posts to accounting

Discrepancies auto-post as equity adjustments. Your ledger stays correct without extra work.

The offline promise

Your business shouldn't stop when the Wi-Fi does.

Rotonda is offline-first by design — not a cloud app with an offline mode bolted on. Everything lives in a database on your phone.

No internet, no outages

Ring up a sale in a basement, a market stall, or a dead zone. The app never waits on a connection.

No cloud, no risk

No data-breach exposure, no vendor lock-in. Nobody else holds your numbers.

Your database, your backup

Your SQLite file lives on your device — back it up to Google Drive whenever you like.

Rotonda POS

Your business, finally on your terms.

Everything stays on your phone. No cloud. No lock-in.
