About this app
Invoice Simple is an invoicing app for sole traders and small businesses who bill customers on the spot: a landscaper finishing a job, a side-gig seller handing over a receipt. It covers invoices, estimates and receipts, and it's built so a document can be written up while standing next to the client rather than back at a desk. Each document can carry a logo, business and banking details, tax and discounts, product photos and a signature. Client details can be pulled in from the phone's contacts. Finished invoices go out by email, text or WhatsApp, or save as a PDF, and the app sends a notification when one is opened, paid or overdue. Switching on Invoice Simple Payments lets customers pay by card, with the processing fee optionally added to the invoice itself. The free tier is a trial. Paid plans start with Essentials, which caps usage at three invoices a month.
Invoice Maker ▸ Invoice Simple: the full guide
What the app is
Picture a landscaper writing up the bill while the client is still admiring the lawn. That is the scene Invoice Simple is designed for: invoices, estimates and receipts produced in the moment, standing up, on a phone, rather than later at a desk.
Documents can carry a logo, business and bank details, tax, discounts, product photos and a signature, with client details pulled from Contacts. Delivery is by email, text or WhatsApp, or as a saved PDF, and notifications report when an invoice is opened, paid or overdue. Turning on Invoice Simple Payments lets the customer pay by card, with the option of passing the processing fee onto the invoice.
How it works day to day
Done with the job, you open the app, pick the client, add the lines, snap a photo of the work if that helps, and sign. It goes out over WhatsApp because that's where the client already is. Two hours later a notification says it's been opened; a day later, another says it's paid by card. Estimates ahead of a job follow the same steps. Receipts for cash jobs are a tap. The app rarely gets more than a minute at a time, which is the point: billing that doesn't wait for the evening.
Why people look for it
Side-gig sellers and trades who've lost track of who owes what search for a way to bill on the spot and know when the money lands. The name promises simplicity, and the 4.9 average across more than a hundred thousand ratings tells browsers that plenty of others found it delivered. WhatsApp delivery is a specific draw in markets where that's how business is done.
Look and feel
Five screenshots here most likely cover a finished invoice, the editing form, the client list and the payments toggle. Invoice apps favour paper-like document previews on a neutral background, with status badges for opened, paid and overdue. The name suggests restraint in the interface, and the on-the-spot use case demands large tap targets, though the listing doesn't describe the design directly.
