Our philosophy
Managing every client lifecycle is fragmented. It should be connected.
The tools around a client were built separately for relationships, projects, contracts, payments, and communication. Hintflow brings them together in one connected layer, where everything shares context, speaks to everything else, and moves forward as one.
Scattered
Client conversations, files, projects and updates are fragmented across different places. Hintflow brings them into one connected layer, organized around the client.
Repetitive
The same details get typed four times, once per tool. In Hintflow, proposals, contracts, projects and invoices share the same client, so every detail is entered once.
Disconnected
Every stage starts from a blank page, so context gets lost between handoffs. In Hintflow, proposals, projects and invoices stay connected to the same client and carry the work forward.
Invisible
Clients shouldn't have to chase you for updates. In Hintflow, they have one place to see progress, updates, files, notes and what's needed from them.
Built for you, and your clients.
Keep the work, contract, and client in one place.
Everything around a project lives on the same client record, from the first scope to the final invoice.
Start with a clear scope
Send the contract, collect a signature, and get the project moving without the usual back and forth.
Keep every revision together
Give clients one place to see the latest work, leave feedback, and keep the project moving.
Invoice when the work is ready
Create the invoice from the project itself, so nothing gets lost between delivery and payment.
Everything you’re probably wondering
You start with a free 7-day trial, then Pro is $29/month or $299/year. Paying annually saves you about two months compared with paying monthly.
Yes. You get 7 days free, with no card required. You can send real contracts and invoices during the trial.
No. Your clients don't need to create an account or install anything. They open their link to view the project, updates, contracts, and invoices. When they need to take an action, they verify their email with a 6-digit code.
Hintflow records the signing process, including the signature, timestamp, verified email, IP address, and document fingerprint. Completed contracts also include a certificate page with the signing record.
Whether an electronic signature is legally binding depends on the applicable law and circumstances. If you need advice about a specific contract or jurisdiction, speak with a qualified lawyer.
Hintflow can prepare contracts, draft invoices, and turn a project into an invoice for you.
