Offline invoicing and thermal printing for field reps

A rep standing in a shop with no signal should not have to write on paper and type it in later. FieldSales keeps customers, products and prices on the phone, so the rep issues the invoice, prints it on a Bluetooth thermal printer and hands it to the customer without internet. The document uploads automatically when the connection returns.

Data on the phone before the signal drops

On the first connection, the app downloads customers, products, prices and company settings to the phone. When the network goes down, everything needed to issue an invoice is already there, with no empty lists or loading screens. Documents are saved in the phone’s storage, so they survive if the app is closed or the phone restarts.

Print at the customer’s door

Invoices and receipts print on a Bluetooth thermal printer paired with the phone. Printing happens on the device, so it works with or without internet. Amounts print in the company’s currency with the right number of decimal places. Receipt vouchers print the same way, at the moment the payment is collected.

Sync once, never twice

Every document gets a unique key on the phone when it is created, and the server refuses duplicates. If the upload fails and retries several times, you still get one invoice. Invoices upload before the receipts that refer to them, and older documents before newer ones, so links between them stay intact.

Nothing hidden from the rep

A counter shows how many documents are still waiting to upload. If the server rejects a document for a business reason, the rep sees it marked as rejected. Saudi companies with e-invoicing integration enabled need a connection when invoices and returns are issued; receipts and visits still work offline.

Can reps print invoices without internet?

Yes. Printing happens on the phone, so an invoice issued offline is printed offline and uploaded later. Saudi companies with e-invoicing integration enabled need a connection at the moment invoices and returns are issued, then print from the phone as usual.

What printer do reps need?

A portable Bluetooth thermal printer that pairs with the rep’s phone. FieldSales does not sell printers or require a specific brand. Receipts print on the same printer as invoices, at the moment the payment is collected.
