Thinking about switching?
If you are currently on Submittable, Fluxx, Foundant, or SmartSimple and weighing up a move to Submit.com, here is what you need to know.
Switching from Submittable
The most common reasons are UK or Irish compliance requirements (Cyber Essentials, G-Cloud), scaling per-user costs, and the need for stronger post-award management. Migration typically takes 4 to 6 weeks with full historical data transfer.
Talk to us about switching →Switching from Fluxx
Organisations switching from Fluxx typically do so because of cost. Submit.com delivers comparable workflow depth at a significantly lower price point, with faster implementation and no per-user fees as your team scales.
See a side-by-side demo →Switching from SmartSimple
SmartSimple's high total cost of ownership — implementation, configuration, and ongoing support — leads many organisations to seek alternatives at renewal. Submit.com offers public sector compliance credentials without the enterprise cost and technical dependency.
Request a migration assessment →Switching from spreadsheets
Many organisations still manage grant applications through email and spreadsheets — creating bottlenecks, version control issues, and compliance risks. Submit.com replaces these processes quickly, with most organisations going live within 4 to 8 weeks.
