How do you handle optional client upsells & MSA contracts on B2B scopes?

Hey Product Hunt! 👋 We're launching ScopeForge Studio tonight at midnight PT (https://scopeforge-studio.scopef...) and wanted to kick off an early discussion with fellow agency owners, consultants, and indie builders.

Every time I scoped a client project in the past, I hated having to maintain 4 separate documents (a Google Doc proposal, a spreadsheet quote, a PDF contract, and a Stripe/QuickBooks invoice) — or paying $49–$79/mo for heavyweight proposal SaaS just to send a few scopes a month.

So we built ScopeForge Studio to run 100% client-side in the browser:

1. One structured scope form generates 4 live-synchronized documents (Executive Proposal, Interactive Quote, Plain-English Master Services Agreement, and Tax Invoice) in 60 seconds.

2. Interactive Good / Better / Best client upsell checkboxes let your prospect toggle optional add-on phases directly on the quote and watch the total + deposit recalculate in <0.2ms.

3. Built-in dual-party HTML5 e-signature pad + SHA-256 tamper-evident audit hash + 200+ pre-built industry templates.

You can test the full studio right now with zero signup required: https://scopeforge-studio.scopef... (and we also built 50+ free interactive B2B pricing calculators at https://scopeforge-studio.scopef...).

Curious for the freelancers, consultants, and agency founders here: do you currently bundle your Proposal, Quote, and MSA into a single link for clients, or send them in separate stages? (Use code LAUNCH30 for 30% off Lifetime Pro if you want to white-label it for your studio!)
