The on-site workflow

From the driveway to done in under a minute.

Walk up to the job. Receiva pulls the nearest client by GPS, then you pile up the services you performed — line items, parts, taxes, notes. Stamp it with your crew and hit send.

If you're off-grid, it doesn't matter. The receipt is saved and queued on the spot — open the app when you're back in range and it sends.

Key features

Everything a tech needs. Nothing they don't.

No subscription servers holding your data hostage. Just a fast, reliable tool that does the receipt and gets out of your way.

Works offline

Everything runs in your browser and stores locally. Receipts queue when you're off-grid and send the moment you open the app with signal.

Email from your own Gmail

Receipts go out from your address, straight to the customer — nothing routed through a middleman server you don't control.

GPS client lookup

Tap once to pull up the nearest client by your current location. The right job is always at the top of the list.

Your data, your device

Catalog, templates, and history live in an on-device database. Optional one-tap backup to your own Google Drive — nowhere else.

Customizable receipts

A layout you arrange yourself: your logo, business info, line items, totals, VAT, and free-text notes — ordered exactly how you want.

Queues offline, sends on open

No signal? Receipts save and queue locally. Open the app when you're back in range and they go out — one tap, no re-entry.
