The Operations Divide

Spreadsheet, drive, e-sign app and email, or one workspace

What a month of client work looks like for a freelancer or agency, before and after Cosmos.

Traditional Disconnected Stack

Multiple standalone tools and manual handoffs

Cosmos Client Operating System

One connected ledger from proposal to payout

Manual Multi-Tax Calculations

Checking whether each client is domestic, an EU business or overseas, then working out the tax by hand.

Dynamic Jurisdiction Routing

The tax treatment is picked from where you and the client are.

Currency Conversion Guesswork

Converting currencies in spreadsheets and losing money on unpredictable bank exchange spreads.

Paid in the client's currency

Invoices go out in the client's currency and settle straight to your own Stripe or Razorpay account.

Fragmented Sign-Offs by Email

Chasing sign-off by email before you can send the invoice.

Integrated Deliverable Approvals

Clients approve milestones in the portal, and the invoice follows.

Tool Sprawl & Scattered Records

Contracts in drive folders, signatures on standalone SaaS, and invoicing in separate accounting software.

Single Unified Client Ledger

Contract, sign-off, invoice and payment link sit behind one client portal link.

Tax handled first, everything else built around it

Tax handling comes first, wherever you and your clients are. Payments, contracts and the client portal are built around it, not bolted on.

View plans
Automatic tax routing by client location

Tax worked out on every invoice, wherever your client is

Cosmos applies the right treatment for each client: domestic VAT or GST, EU reverse charge, or a zero-rated export in the client's currency. Switch the tabs to see one job billed three ways.

Dynamic Jurisdiction Engine

Rates and rules come from your workspace's tax jurisdiction, not hardcoded tables

Automated Reverse Charge

EU B2B reverse charge with the customer's VAT ID and the required wording

Billed in the client's currency

Exports billed in the client's own currency at 0%

Frozen once issued

The tax breakdown and client details stay as they were when you issued the invoice.

Paid straight to your bank

Clients pay by card, bank transfer or local methods like UPI from the invoice link. Stripe Connect and Razorpay Route settle to your own account; Cosmos never holds the money.

A client portal with no login

Clients open one magic link to see invoices, sign contracts and approve work. No account to create, no password to forget.

Sign-off before you bill

Send a contract from a template, then have the client approve each milestone before it's invoiced. Signed copies are sealed with a SHA-256 hash.

Lead, quote, invoice

Track a lead to an accepted quote, then turn the quote into an invoice without retyping a single line item.

From Signed Contract to Paid Invoice

Contract & E-sign

Send a contract from your template. The client signs from the portal link and the signed copy is hash-sealed.

Project Setup

Kick off the project with scope, milestones, and deliverables.

Invoice & Payment

An approved milestone becomes a tax invoice. The client pays online, and the money settles straight to your bank.

Reports & Follow-up

Overdue invoices get reminders on your schedule, and the ledger shows what's billed, collected and still owed.

Billed, collected and outstanding, in one report

Export the billing ledger, with every invoice, its settlement date and what's still owed, as a PDF for your accountant or your client.

Trust built into the workflow

Client contracts, tax invoices, and payment records require reliable record-keeping.

Cosmos keeps client-facing access separate from internal workspaces, limits operational access by role, and keeps business records exportable.

Payments run through Stripe or Razorpay

Card and bank details are entered with the payment provider, and the money settles to your own account. Cosmos never holds it.

Where your data lives

Records are stored in Postgres on Neon, and uploaded files in Cloudflare R2.

Access scoped by role

Team permissions follow workspace roles. Clients get a private portal link, not a login to your dashboard.

Records you can take with you

Invoice, contract and payment history stays exportable if you leave.

Cosmos is in beta. If something looks wrong, email support@cosmos.io.
