Easy and orginized

This is the first app I've ever bought. That's how awesome it is. Typically I don't buy apps since they are difficult or I can't see myself getting my money's worth out of it. That all changed with this app. Being a consultant and small business owner I do a lot of invoicing and billing to clients. They are typically very confused and can't understand the costs. However, with this, it is easy to read, well laid out, and sooo easy to prepare. The ability to text it or email is a life saver for those who have smartphones now. All I can say is if you write invoices periodically, you need to get this! Only down side is you can't shuffle or move the new items around once you've typed them in. They need to be in order as you type them. If there is ever an update I would love to see that feature just in case I got something out of order so I don't have to erase things. Other than that, it is perfect and a must have!!

Ivy Patch Produce

Perfect Simple Invoice App

I recently sold my tiny organic produce store and have just started a market garden. I plan to sell a few things to the store this season, only basil and sugar snap peas next week. Next year I should be really starting to crank out the veggies. Rather than fiddling with paper receipts, I decided to download an invoice app. This app is so elegant, you would think that someone read my mind and added everything necessary and no fiddly useless stuff. I love that I can create an estimate that later can be updated to an invoice. It saves a library of items, so I don’t have to re-enter each product with each new invoice. Client information is saved so that it can automatically be entered into the document. There is a place to put your logo and there are a number of different layout options from simple to professional. It allows you to send the invoice directly from the app. Perfect!


Great App for Invoicing

Initially downloaded this app just to play around and see how easy or difficult to use it would be, what features I would be able to use if any, and how professional it would look as a small business owner. I mist say I ended up purchasing this app. Its very easy to use, gives you a very professional look, and has some pretty neat features. I can upload my business logo to add to the top of the invoice, add individual items into the app itself so I can easily have description and priced stored for quicker invoices, Record payments and multiple ones at that. In my sweets business I always require a deposit 3 weeks in advance and balance due 1 week before pick up/delivery and being able to record multiple payments are a great way to keep track of everything. The customers find it very easy to read and understand the invoice. LOVE LOVE LOVE this app.
