1 Overview
I look after new conversations at InterioApp, the quoting software and online store team for curtain, blind and shutter retailers. The owners I work with usually have a showroom, a small team and quotes done by hand in the evening. I help them see what we can build together: quoting software for the showroom and home visits, a price calculator on their website, or a complete online store set up from their product list and supplier price lists. InterioApp started as a calculator for our founder Darius Baltunis's own curtain shop. He has been in the trade since 2011 and often joins my calls.

This season I am helping curtain and blind retailers get an online store ready for Christmas and the January sales, built as a business with a price calculator on every made to measure product. I also write here about how independent shops get found by Google and AI.

7 Q & A
- What happens when I book a call with InterioApp?You speak with me, Jemma, for 30 minutes on a video call, at a time that suits you in the UK or the US. Darius Baltunis, our founder, often joins us. We talk about how you quote and sell today and what would help most: quoting software, a price calculator on your website or a complete online store. There is nothing to prepare.
- Who does InterioApp work with?Curtain, blind and shutter retailers, from independent shops with a showroom and a small team to larger chains. Our clients are in the UK, Ireland, Europe, the United States, Australia and New Zealand.
- What does InterioApp cost?The quoting software is £99 per user per month, with a one-off setup of £1,800. A price calculator on the store you already have is £1,800 to set up and then £79 a month. A complete online store is a different game, because we build the whole business with you, and it comes as a one-off package: Store Launch £10,000, Omnichannel £19,500 or Market Leader £35,000.
- Does it actually make a difference to a shop?Our own curtain shop, ADmaja in Lithuania, has used it since 2017. In Window Fashion VISION in 2020, Evelina Baltune of ADmaja said the shop had saved almost 5 percent of its annual revenue in two years, just by removing mistakes from calculations done by hand.
- Can AI not just do our quotes?AI is good at explaining, drawing and writing, and we use it every day. On its own it does not know your supplier price grids, your rules or your margins. A quote is a promise with a number on it, and that number has to come from your price lists, through logic that is tested.
