Professional E-commerce Development Team, Smooth Delivery From Start to Finish

Isla Harris / Chief Digital Officer | Oct 13, 2026

We were very happy with how this project went. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

We are already seeing better numbers than before the project. Overall, a team we trust and plan to keep working with.

Project summary

Altar.io was brought in to build a Shopify store with custom features for our product range. They also took care of integrations with a couple of third-party tools we already used. We worked together for around 6 months.

Great Experience With Altar.io on Our Software Development Project

Kavya Iyer / Director of IT | Sep 03, 2026

We were happy with the final result. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline.

The Software Development work has already made a noticeable difference — tasks that used to take hours now take minutes. Their team changed one developer midway, which slowed things down for a couple of weeks. Happy to recommend them.

Project summary

We engaged Altar.io to build a custom operations platform to replace the spreadsheets and email threads we were running the business on. The work covered requirements, design, development, testing and launch support. Overall it was a 9-month engagement.
