Pitch it, sign it, bill it, and know where you stand.
Most invoicing tools assume a steady drumbeat of monthly billing, and quietly punish you when you go quiet for a quarter. RunwayDue is built for the opposite: lumpy projects, long sales cycles, and the stretch between a signed contract and the first payment.
- No card to start
- GST and US sales tax built in
- Your records are yours on any plan
Tax worked out, chased on its own
Most US professional services are not taxable, so nothing is added here. Turn sales tax on and you set the rate — we do not look it up by address, and we do not check where you have nexus.
The idea
Four layers of revenue, never added into one number
A business with lumpy revenue cannot answer “how am I doing?” from an invoice list. So every number is built from one of four layers, in descending order of certainty, and shown side by side rather than summed.
Payments that have actually landed. This is the only number that is genuinely yours, and it is the only one most tools show you.
Where it comes from: Recorded against an invoice, with the reference from your bank.
Revenue outlook
Six months, with collected picked out
The layers are never added into one headline number. That is how people talk themselves into revenue that does not exist.
The loop
From a pitch to a set of books, without retyping anything
Each step feeds the next. A win moves from hope to signed to committed to money owed to money in, and what it cost you lands beside it. Click through, or leave it running.
Step 1 of 6 · Propose
Write it here, or upload the one you already wrote
Build the proposal in the editor, or drop in the PDF you spent all week on. Either way it is a proposal: it counts toward your pipeline, weighted by how likely you are to win it.

Signing
Do not take our word for it. Sign this one.
Every tool describes its e-signature and almost none of them let you try one. Draw or type below and watch it land on the agreement, with the trail filling in as it happens. Nothing leaves your browser.

Audit trail
Everything that happens to a document is recorded here, and bound into the finished PDF as a certificate of completion.
Sign here
Take as many strokes as you need — lifting the pen does not end it. Nothing is uploaded and nothing is stored: this runs entirely in your browser.
These are electronic signatures with a full audit trail, which is what almost every commercial agreement needs. They are not certificate-based digital signatures, and some instruments cannot be signed electronically at all. The app says which, before you send.
Your books
Same month. Two answers. Both correct.
Now that costs live here too, the app can tell you what you actually earned rather than only what you invoiced. Which is a different number depending on the question, so it answers both. Flip the switch.
October, one business
Five things happened. How many count depends on which question you asked.

Accrual is the honest picture of a month's trading: work you did counts even if nobody has paid, and costs you incurred count even if you have not settled them. It is what a statutory profit and loss uses.
Profit and loss
On either basis, with cost of sales split from overheads.
Cash flow and balance sheet
What moved each month, and what the business owns and owes.
Ageing and tax
Who owes you and how late, who you owe, and what you have collected in tax.
What else
The unglamorous things, done properly
Signing that holds up
Named signers, fields dragged onto the page, and a signature drawn, typed or photographed. The finished PDF carries a certificate listing who signed, when, from where, and the fingerprint of the original.
Bring your own documents
Already have the proposal, or an MSA your lawyer drafted? Upload the PDF and it behaves like anything else here: it counts toward pipeline, it converts, it schedules the billing, it raises the invoices.
Tax that knows where you bill from
In India, your state against your client's decides CGST and SGST or IGST, GSTINs are checksum-validated, and the editor says why in plain English. In the US, one sales-tax rate a line, which you set. Anywhere else, a rate you set yourself rather than tax rules we have not written.
Chasing that firms up in stages
A heads-up before it is due, a note on the day, then follow-ups that go from understanding to direct. Never threatening, always asking for one specific thing. Unsigned documents get chased too.
Retainers that bill themselves
Weekly, monthly, quarterly or yearly, raised as a draft you check or issued without asking. Two brakes, so a schedule everyone has forgotten cannot bill a client forever.
Answers you cannot get elsewhere
Average days to get paid. Months of runway already secured. How much of your revenue rests on one client. What you owe suppliers, and how late you are.
Any currency, one set of books
Bill in dollars, euros or rupees. Every report converts at the rate saved on each document, so a report never silently re-rates history at today's number.
Roles, including one for your accountant
Owner, admin, member and a read-only viewer. Enforced on the server for every action, not just hidden in the interface. Your accountant reads everything and changes nothing.
Reports that agree with each other
The bank line on the balance sheet has to equal the closing balance on the cash flow. There is a command that checks it. A report that balances is not the same as a report that is right.
Nothing you make here is ever deleted for not paying
Stop paying and the workspace drops to the free plan. Every invoice, proposal, contract and signed PDF stays exactly where it is, and you can still open it, send it, chase it and record payment against it. What a plan limits is what you can *start* next. Export is a Pro feature — but your right to your own data is not conditional on a subscription, so if you are on Free and want the lot as files, write to us and we will send it. If you would rather it were gone than dormant, ask and we will delete it instead.
Try Pro free for 14 days
Every Pro feature, no card. When the 14 days are up you drop to the free plan rather than to a paywall — nothing is locked, nothing is deleted, and everything you made in the trial is still yours.
- No card to start
- Drops to Free, never to a wall
