The agency OS that closes deals,
runs projects, and impresses clients.
Draft the proposal with AI. Give every client a portal login. Run projects, meetings and GST invoices with pay links from one workspace.
Works with the tools you already use
A day with sync.d
Less admin. More time for the people you work with.
From the first call to the last invoice, the busywork runs in the background.
Illustrative photos of the kind of work sync.d is for, not sync.d customers.

Win deals faster.

Chat with the client. Turn their emails into tasks.
Every project has one message thread for your team and the client: markdown, @mentions with email alerts, threaded replies, reactions and typing indicators. Each project can also get its own forwarding address. Forward a client email there and it becomes a task on that project, tidied up by AI when you have added an OpenAI key.
- Mention any teammate or client by typing @
- Per-project
tasks+token@forwarding address - Unread counts on every project thread
One click. PayPal, Polar or Wise. The client picks how they pay.
"Send to client" mints a per-invoice checkout link on the gateway you choose, with the exact total and the client's email pre-filled. Bank details always ride along on the PDF so non-Wise / non-PayPal clients can still wire directly. GST-compliant for Indian agencies, multi-currency for everyone else.
- Per-client checkout via Polar or Wise, or your PayPal.me link
- UPI ID printed on the invoice
- Recurring invoices go out on a set day, monthly or quarterly

Pitch
AI drafts the proposal from a short brief. The client answers your questionnaire and signs online.
Kickoff
The client books the kickoff from their portal. Round-robin picks which designer takes the call.
Delivery
Milestones, tasks and one message thread per project. The Workload page shows who has what due.
Billing

Team, $89 a month: up to 10 users with Owner, Admin, Manager and Member roles.
Example setupFree or Pro

Start
The Free plan has every feature: 3 proposals and 5 invoices a month, and 2 active projects at a time.
Calls

Notes
Record the call with the browser extension. AI writes the minutes and files the action items as tasks.
Invoice

Free to start. Pro, $39 a month, removes the monthly limits.
Example setupAny plan
A dev shop billing in USD and INR
Clients in India and abroad, and a CA who wants clean numbers.
INR
Each INR invoice works out IGST, or CGST and SGST, from your GSTIN state and the place of supply.
USD
Invoices in USD or another currency go out as export of services, with no GST lines.
TDS
Private billing notes remind you which clients deduct TDS, and at what rate.
Month end
Export one CSV with separate IGST, CGST and SGST columns for your CA.
Any plan. GST and multi-currency invoicing are on Free too.
Why we built sync.d
We built it for our own client work first.
sync.d started as the tool we built to run client work at Digithink Technologies in India. We wanted proposals, GST invoices, client calls and project updates in one place, with one record per client and a login where each client could see their own projects.
In 2026 we opened it to other agencies and freelancers.
It is early, so there are no customer reviews on this page yet. Book a demo or start on the Free plan, and judge the product for yourself.

FAQ
Questions, answered.
sync.d is one workspace for agencies and freelancers. It covers AI proposal drafting, GST invoices with PayPal, Polar and Wise pay links, a client portal with client logins, Google Calendar meeting booking, project messages and AI meeting minutes from call recordings. It can stand in for separate tools like Notion, Calendly, FreshBooks and Slack. There is a free plan, Pro is $39 a month for one person, and Team is $89 a month for up to 10 users.
You invite a client contact, they set a password from the invite email, and they sign in to a portal under your company name. A one-time email link works as a fallback. They see their own projects, milestones, meetings, tasks, progress reports and messages. The main contact can invite colleagues and choose which projects each one sees, and invoices stay hidden from client staff until financial access is granted.
Yes. Each teammate connects their Google Calendar. sync.d reads free/busy so clients only see open slots, creates the event with a Google Meet link, and emails the client a reminder within a day of the call. When a meeting is moved or cancelled in sync.d, the calendar event is updated too.
Yes. Clients book from the project in their portal. They pick a slot, get an email with the Google Meet link, and can reschedule or cancel from the portal or that email. Round robin can share the bookings across your team, and workspace holidays block booking on those dates.
Record a Google Meet, Zoom or Teams call with the sync.d browser extension for Chrome, Firefox or Safari. The audio is transcribed and AI writes the minutes: a summary, decisions and action items, with the action items filed as tasks on the project. You can also paste your own notes instead. The minutes go to your team first, and you choose when to send them to the client or turn on automatic sharing.
Yes. Every project has one message thread for your team and the client, with markdown, @mentions that send an email, threaded replies, reactions and typing indicators. New messages show up while the page is open, and each project shows an unread count.
Yes. Add your OpenAI API key in Settings and the AI drafts the scope of work, deliverables, website structure and terms from a short brief. Without a key you get a template draft to fill in. Everything stays editable before you send it. Clients open the proposal from a share link in any browser and can sign it without an account.
Yes. Every invoice can carry your PayPal.me link, and Polar, Wise, UPI and bank transfer are supported too. You mark the invoice paid when the payment lands.
Yes. You set your logo, brand colour and signature image, plus your company, bank and GST details. They appear on your proposals, invoices and PDFs, and the client portal shows your company name. Client emails go out under your company name. Connect Gmail or your own Resend domain to send from your own address; otherwise they come from our address as Your Company via sync.d. A custom domain for the client portal is not available yet.
sync.d runs on Cloudflare, with data in Cloudflare D1. Sessions use HttpOnly, Secure cookies. Sign-in links work once and expire. All traffic is over HTTPS, and sign-in and other sensitive endpoints are rate limited.
