Pricing ❌ Managing complex pricing tables manually is a hassle. ✅ Super easy to set up flexible and interactive pricing that fits your structure.
Brand consistency ❌ Poorly designed proposals that don’t impress clients. ✅ Stunning on-brand proposals delivered quickly make clients trust you.
Integrations ❌ Updating information manually between systems will lead to inconsistencies and data silos. ✅ Data is synced with CRMs and your favorite tools.
Tracking & analytics ❌ You don’t know anything about what your leads do with proposals. ✅ You know exactly when the proposal is opened, read, signed, etc.
Security & compliance ❌ Sending documents back and forth with emails is a sure way to make errors and leaking data. ✅ Legally binding e-signatures, GDPR, and security is handled in all in one tool.
