A reliable long-term partner for our tech needs

Thijs Bakker / Founder & CEO | Oct 12, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They shared working builds regularly, so we could test early and give feedback before things were locked in. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

Since launch, everything has been stable and our team has adapted to it quickly.

Overall, a team we trust and plan to keep working with.

Project summary

Our company worked with SellerSupport to develop a field-staff app with offline mode that syncs back to our main system. The project was split into milestones, with a working build shared at the end of each one. The engagement ran for about 2 months.

Great Experience With SellerSupport on Our Mobile App Development Project

Hui Min Goh / Chief Digital Officer | Aug 29, 2026

We were very happy with how this project went. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

The Mobile App Development work has already made a noticeable difference — tasks that used to take hours now take minutes. We would definitely work with them again.

Project summary

SellerSupport was brought in to build iOS and Android apps for our customers, including booking, payments and push notifications. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 4 months from kickoff to launch.

Delivered on time and stayed involved after launch

Sara Saleh / Program Manager | Aug 21, 2026

SellerSupport did good work for us, and we would use them again. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They shared working builds regularly, so we could test early and give feedback before things were locked in. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

We launched on schedule and have not had any major issues since. Their team changed one developer midway, which slowed things down for a couple of weeks.

We are already discussing the next phase with them.

Project summary

Our company worked with SellerSupport to build a demand forecasting model on top of our sales data. They worked alongside our in-house team, which mostly handled business requirements and testing. We worked together for around 2 months.

Honest advice and solid execution

Sarah Leblanc / Director | Aug 17, 2026

We were happy with the final result. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

It has made a real difference to how our team works day to day. Their team changed one developer midway, which slowed things down for a couple of weeks. We are already discussing the next phase with them.
