Small businesses, freelancers and contractors who need to get an invoice out quickly from a phone are the target for Invoice Fly. The flow is four steps: tap create, pick a client from contacts, add items and prices, then save and send. Estimates follow the same path and convert to invoices with a tap. Invoices can carry payment information, taxes and withholding, due dates, extra images, discounts (per item or on the total), notes and a signature, and there are several templates to customise. A notification arrives when the client receives and opens the invoice, which takes some of the guesswork out of chasing. Invoices can be shared or printed from the phone, data syncs across devices on one account, and simple reports track income. Support is available around the clock, according to the developer.
Four taps to an invoice is the promise. Create, choose a client from your contacts, enter the items and prices, send. Invoice Fly is built for small businesses and contractors who need the bill out of the door while the job is still fresh, and estimates follow the identical route before converting with a single tap.
Each document can hold payment details, tax and withholding, a due date, photos, discounts, notes and a signature, with several templates to tweak. The feature that separates it from a PDF generator is the read receipt: you get a notification when the client opens the invoice. Income reports and cross-device sync sit alongside.
Picture the end of a job. You tap create, pick the client, list what you did, add a photo of the finished work and sign. It's sent before you reach the car. Later your phone tells you the client has opened it, which turns the awkward follow-up call into an informed one. Estimates earlier in the week went out the same way and converted when accepted. The reports screen gets a glance at month end to see what came in. On a second device, everything is already there.
Speed is the search intent here: people want an invoice done on the phone in under a minute and don't want to learn accounting software to do it. The open notification is the detail that gets repeated in conversations, because knowing the client has seen the bill changes how you chase it. The 100K-plus rating count adds reassurance.
A four-step flow suggests a wizard-like interface, and the five stills probably walk through it: client, items, preview, sent. Templates will appear as a gallery. Apps in this niche favour white forms with a single accent colour and a document preview that looks like paper. Nothing in the listing points to anything more elaborate.
Version 2.47.0 means dozens of releases within the second major version, which usually reflects steady work, although there's no date in the data. More than a hundred thousand ratings at 4.8 is a large and positive sample for a utility app. Labhouse Mobile SL has only the App Store listing linked here; the SL suffix points to a Spanish company.
Sub-minute invoicing
Create, client, items, send: the four-step flow is built for speed over configuration.
Read-receipt billing
Knowing the moment a client opens the invoice takes the guesswork out of following up.
Multi-device sole traders
One account keeps every device in step, so the iPad at home matches the phone on site.
Free to download and rated 4+. The listing we have is silent on pricing beyond that, so whether there's a subscription or a document cap is unknown and worth checking first. An account is implied by the cross-device sync.
Contacts permission is needed to pull clients in, and a connection is needed for sending and for the read notifications. Round-the-clock support is claimed by the developer. Regions, ads and storage aren't addressed.
Our take
A sensible choice for anyone whose invoicing is simple and frequent and who values speed over depth; the read receipt is a small feature with outsized usefulness. Businesses needing recurring billing, stock or purchase orders will outgrow it. And check the pricing before you build your client list in it, since the listing doesn't tell you.
