Free proposal, invoice and contract tools for freelancers
Most freelance income is lost in the paperwork gaps — a quote with no scope, a draft handed over before payment, an invoice chased with five identical reminders. Solo OS is 11 document generators covering the whole engagement, from the proposal that wins the work to the legal notice that recovers the fee.

The engagement
Five stages where freelance projects lose money
Every stage below has a document that closes it. Skipping one rarely costs you anything immediately — it costs you at the next stage, when you have no paper to point at.
Win the work
Pitch a number, not a conversation
A quote sent as a chat message has no scope, no validity date and no pricing tiers. It gets negotiated down, or compared against someone who sent a document.
Set the terms
Agree the boundary before the first file moves
Scope creep is not a personality problem, it is a documentation gap. Without a written deliverable list, revision count and payment schedule, every extra request looks reasonable.
Scope of Work Generator
Define deliverables, timelines, and payment terms before starting any freelance project.
Open toolUPI Invoice Generator with QR Code
Professional invoices with embedded UPI payment QR codes and GST compliance for Indian freelancers.
Open toolMutual NDA Generator
Balanced Non-Disclosure Agreement that protects both parties and preserves your portfolio rights.
Open toolProtect the drafts
Share previews without shipping the asset
A clean, full-resolution draft sent over email is a finished deliverable the client already has. Leverage disappears the moment you hand over the source file.
Get paid
Escalate on a schedule, not on emotion
Most freelancers send three versions of the same polite reminder. A real escalation ladder changes tone, cites the contract, and ends somewhere the client would rather not go.
Close and compound
End the project on paper so it stops costing you
Projects that are never formally closed keep generating "quick changes" months later — and you still cannot show the work in your portfolio without written permission.

The rules that decide whether you actually get paid
Indian freelancers work under a specific set of thresholds and deadlines. Most people learn them the expensive way, one dispute at a time. Every figure here links to its source.
- When do I have to register for GST?₹20 lakh aggregate turnover
- The threshold drops to ₹10 lakh in special category states. Registration is required from the first rupee if you import services, regardless of turnover.TaxAdda — GST on freelancersBuild a GST-ready invoice →
- Do I charge GST to a foreign client?Zero-rated, if you file an LUT
- Export of services is zero-rated. File a Letter of Undertaking and you invoice without charging IGST; skip it and you pay IGST first and claim a refund later.TaxAdda — GST on freelancers
- Can I skip maintaining full books?Section 44ADA — declare 50% as profit
- Professionals within the prescribed gross-receipts limit can presume 50% of receipts as taxable income. The limit is higher when cash receipts stay at or below 5% of the total.ClearTax — Section 44ADA
- Why did the client pay less than the invoice?TDS under Section 194J
- Professional fees are typically deducted at 10% and technical services at 2%. It is withheld tax, not a discount — it appears in your Form 26AS and you claim it back when you file.ClearTax — Section 194JWork out the deduction →
- How long can a client legally take to pay?45 days from acceptance
- Under Section 16 of the MSMED Act, 2006, a buyer who pays a registered micro or small enterprise later than 45 days after accepting the work owes compound interest with monthly rests at three times the RBI bank rate.MSME Samadhaan (Ministry of MSME)Calculate what you are owed →
- Does that protection apply to me automatically?Only with Udyam registration
- The delayed-payment machinery is open to micro and small enterprises holding a valid Udyam registration. Unregistered freelancers meet the size criteria but cannot file — registration is free and is the highest-leverage hour of admin on this list.MSME Samadhaan (Ministry of MSME)
- Where do I actually file a complaint?The MSME ODR portal
- Samadhaan now routes new delayed-payment applications to the online dispute resolution portal. The case goes to your state Facilitation Council, which must dispose of it within 90 days.MSME ODR portalSend a legal notice first →
On the interest figure. Under Section 16, MSMED Act, 2006 a late-paying buyer owes 3 × RBI bank rate, compounded with monthly rests. We state the formula rather than a percentage on purpose — the RBI bank rate moves, and a hardcoded number would be quietly wrong within a quarter.

How it works
“No uploads” is an architecture, not a promise
Plenty of free tools say your data is safe and then post your file to a server to process it. The distinction matters most in the exact situation freelancers are in: you are handling someone else’s confidential brief under an NDA you signed.
If the file never leaves the tab, third-party disclosure is not a question you have to answer.
The document never becomes a request
Filling in a proposal updates state in your tab. There is no autosave endpoint, no draft sync, and no telemetry carrying field contents. Open your browser network panel while you type and nothing leaves.
PDFs are generated on your machine
Export runs a JavaScript PDF library in the tab and hands the resulting file to your downloads folder. Client names, rates and invoice amounts are never assembled on a server.
Saved work lives in browser storage
Drafts and your saved freelancer and client profiles persist in browser storage, scoped to this device. Nobody at Solo OS can read them, reset them, or hand them to anyone who asks.
The tradeoff you should know about
Local-first means local-only. Clear your browser data, switch machines or use a different browser and your saved drafts are gone — there is no account to restore them from. Download the PDF for anything you need to keep.
Micro tools
The small jobs between the documents
18 single-purpose utilities for the tasks that interrupt a delivery — a PDF to split, a client logo to convert, a late fee to work out. Same rule as everything else: the file stays on your machine.

Saved profiles
Fill your details in once
Your business details and your regular clients are stored in this browser and offered as a one-click fill on every document, so you are not retyping a GSTIN into the eleventh invoice of the month.
Where it applies
Every document tool
Proposals, invoices, scopes of work, NDAs and legal notices all read from the same saved profile.
Is Solo OS actually free, or free until an export?
Free through the export. Every generator lets you fill in the document, preview it and download the finished PDF without an account, a trial, or a watermark on the output. There is no paywall between you and the file.
Do I need to create an account?
No. There is no signup, no email capture and no login wall. Because your work is stored on your own device rather than in an account, there is nothing to log in to.
Where is my data stored?
In your browser, on your device. Documents are drafted in memory and saved to IndexedDB and local storage; PDFs are generated by JavaScript running in your tab. Client names, invoice amounts and uploaded files are never transmitted to a Solo OS server.
Can I use these documents with an NDA-bound client?
That is the reason the tools are built this way. A confidential brief pasted into a cloud tool has left your control; the same text pasted into Solo OS has not left the tab. Check your specific NDA, but local-only processing removes the third-party disclosure question entirely.
Are the contracts and legal notices enforceable?
They are professionally structured starting points, not a substitute for a lawyer. A well-drafted scope of work and a formal legal notice carry real weight in a payment dispute, and both are far stronger than a WhatsApp thread. For a high-value contract or an escalation you intend to litigate, have counsel review the final document.
Do the invoices handle GST and UPI?
Yes. The invoice generator produces GST-ready invoices for Indian freelancers and embeds a UPI QR code directly in the PDF, so a client can scan and pay from the document instead of asking for your bank details.
What happens to my drafts if I clear my browser data?
They are deleted permanently. Local-first storage is a privacy guarantee, not a backup service — there is no account to restore from. Download the PDF for anything you need to keep, and treat the saved draft as a convenience rather than an archive.
Does it work offline?
Once the page has loaded, the document tools run without a network connection, because generation happens in your browser rather than on a server.
