*Socket extra fees: Socket charges extra for advanced functionality. ‘Pro Features’ and ‘Socket Engage’ is included in this example.
*GoProposal assumptions: We estimate required plans based on around 0.1 proposals per client per month (e.g. 100 clients ≈ 10 proposals, so Basic). Pricing also assumes an extra £40 per user above the users included in each plan (Solo: 1 user, Basic: 1, Standard: 2, Premium: 10).
*BrightManager assumptions: BrightManager pricing includes an estimated BrightPropose add-on based on the same proposal volume assumption of around 0.1 proposals per client per month. We map this to BrightPropose’s Basic (5 proposals, £50), Essentials (20, £100) or Advanced (35, £150) package and add that cost on top of the standard BrightManager per-user fee.
*Other assumptions: All pricing is based on publicly available information as of the 29th of November 2025.
