Oto
Oto runs invoicing, proposals, contracts, time tracking, expenses, and client payments for solo freelancers in one web dashboard.
If you are a one-person business tired of paying for three separate subscriptions to invoice, propose, and contract, Oto's free tier is hard to argue with — unlimited invoices, proposals, contracts, time tracking, and expenses for $0, capped only at 1 client and 250 AI credits. Upgrade to Starter at $6/mo billed yearly for a second client and custom branding, or Pro at $24/mo billed yearly for unlimited clients and the no-login client portal. The catch is honesty about maturity: the pricing page still marks online timesheets, live timesheets, and time insights as 'Soon', there is no mobile app, no multi-user support, and Oto's feature set is narrower than Bonsai or FreshBooks on the

Skip Oto if more than one person needs to log in to run your billing, since there is no multi-user support and your whole team would share one account.
Oto sits at the cheap end of freelance back-office tools. Free covers unlimited invoices, proposals, contracts, and time tracking for 1 client. Starter at $6/mo billed yearly adds custom branding and a second client. Pro at $24/mo billed yearly removes client, email, storage, and AI credit limits and adds the client portal. For comparison, Bonsai and FreshBooks both charge more per month for comparable billing and document features, so Oto's paid tiers suit cost-sensitive solopreneurs rather

- +AI proposal generation speeds up the most time-consuming part of freelance work.
- +Automatic payment reminders have cut down on chasing late invoices.

- −Recent updates have confused users; controls are harder to find after redesigns.
- −Free tier is quite limited — effectively a trial.
- −No built-in project management, so it won't replace tools like Asana or Trello.

About Oto
Oto is a web-based back-office platform for freelancers. The core loop is straightforward: log your hours, turn them into an invoice in one click, and let clients pay through a Stripe or PayPal payment link in one of 135+ supported currencies. Alongside billing, Oto covers AI-generated proposals, legally vetted digital contracts with e-signature, expense tracking with receipt uploads, and a light client CRM that stores contact details, project history, and a document log. Automation is the selling point — payment reminders and overdue notices go out on their own, partial payments and deposits let you collect before work starts, recurring invoices handle retainer clients, and Oto auto-generates the email copy that goes out with invoices, proposals, contracts, and receipts. Pricing is freemium with a genuinely usable free tier: unlimited invoices, proposals, contracts, time tracking, and expense tracking, plus 250 oto AI credits and 1 client. Starter runs $6/mo billed yearly and adds custom branding, custom contracts, 1,500 AI credits, and 2 clients. Pro runs $24/mo billed yearly and lifts client, email, file storage, and AI credit limits entirely while adding a no-login client portal where clients can view live timesheets, invoices, proposals, and contracts. Oto is built for solo service providers — designers, writers, videographers, consultants — not for agencies. It has no multi-user support, and several time-tracking features the marketing pages advertise (online timesheets, live timesheets, time insights) are still flagged 'Soon' on the pricing page.
Behind the Verdict
Oto's pitch is consolidation, and on the billing-and-documents axis it delivers. The workflow it's built around — track hours, invoice those hours in a click, send a payment link — is the daily reality of hourly freelancing, and doing it inside one dashboard instead of across a timer app, an invoicing app, and a contract tool is a real time saving. The AI layer is used where it's cheap to be useful: generating a draft proposal from a short prompt, describing your services, and writing the email copy that accompanies invoices and reminders. The proposal-to-invoice conversion is a one-click step, so the document chain stays intact from pitch to payment. Contracts are pre-written and legally vetted with e-signature built in, which removes the separate DocuSign-style subscription for most freelancers. The payment side is sensibly unambitious: Oto charges 0% its own fees and you pay only whatever Stripe or PayPal charges for card processing. Clients can approve proposals online, pay deposits or partial amounts as work progresses, and pay in 135+ currencies, which matters if you bill internationally. Automatic reminders and overdue alerts mean you stop chasing invoices manually. The honest weaknesses are three. First, maturity: several features the homepage advertises — online timesheets, live timesheets (both time-tracking views), time insights, late fees, auto responses, expense reports, expense insights, invoice templates, subscriptions, and payment links — carry a 'Soon' label on the pricing page, so what you read on the marketing site is not all shippable today. Second, scope: Oto is explicitly single-user. There is no multi-user support, and the client limits (1 on Free, 2 on Starter, unlimited on Pro) are the real constraint on growth, not the invoice or proposal limits. Third, ecosystem: it is not an accounting system, so you will still need something else for tax, ledgers, and reporting, and the deep accounting integrations freelancers ask for are not part of the picture here. Where Oto fits best: a solo consultant or creative billing 3-10 clients a month, invoicing hourly or per project, who wants one login and one card on file. Where it does not: agencies with more than one person touching the books, anyone who needs project management (no Kanban or task boards — only time tracking), and anyone whose accountant requires ledger-level integration.

Real-world workflow fit
Concrete scenarios for the personas Oto actually fits — and what changes day-one when you adopt it.
Logs hours through the week against each client, then at month end uses Oto to turn tracked time into invoices, applying the recurring invoice setting for the two clients on fixed retainers.
Outcome: Invoices go out without a manual rebuild, automatic reminders chase the overdue ones, and payment links let clients pay by card in their own currency.
Writes a short prompt in Oto to generate a draft proposal, edits the scope and pricing, sends it for online approval, then uses the pre-written contract with e-signature once the proposal is accepted.
Outcome: Proposal and contract go out the same day, the deposit is collected through a payment link, and the accepted proposal converts to an invoice in one click when the work is done.
Tracks billable and non-billable hours separately, uploads equipment receipts as expenses, and sends payment links in the client's local currency.
Outcome: One dashboard holds the invoice history, expense record, and client document log, replacing a separate timer, invoicing, and receipt-tracking app.
Use Cases
- Automate monthly invoicing for retainer clients using recurring invoices.
- Create an AI-generated proposal and let the client approve it online.
- Track hours and send clients a link to your logged time.
- Collect a deposit or partial payment before starting a project.
- Keep client contacts, documents, and payment history in one record.
- Upload receipts and categorize spending for expense reimbursement.
- Invoice internationally by accepting payment in 135+ currencies.
- Send, sign, and track a pre-written contract without a separate e-sign tool.
Limitations
- Oto is single-user: there is no multi-user or team support, and client limits are the binding constraint across tiers (1 client on Free, 2 on Starter, unlimited on Pro).
- The pricing page still flags a set of advertised features as 'Soon', including online timesheets, live timesheets, time insights, late fees, auto responses, expense reports, expense insights, invoice templates, subscriptions, and payment links — so not everything on the marketing site ships today.
- Oto is a billing and document tool, not accounting software: it does not handle tax filing, ledgers, or financial reporting, and the docs and developer pages were not available to review this run, so nothing can be said about API or developer tooling either way.
- No specific underlying AI model is named anywhere in Oto's public pages.

Setup time & first value
How long it actually takes to get something useful out of Oto — broken out by persona, not the marketing-page minute.
A solo freelancer can create an account, connect Stripe or PayPal, and send a first invoice or payment link in under an hour, with no credit card required to start on the free tier. Adding your logo, brand color, and custom contract templates on Starter takes another short session. Getting a proposal drafted with AI is a single prompt away.
Switching to or from Oto
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a generic invoice template: recreate your line items in Oto, set recurring invoices for retainer clients, and switch payment collection to a Stripe or PayPal payment link.
- →From a standalone e-signature tool: move your standard agreement into Oto as a custom contract on Starter and send it from the same place you invoice.
- →From a spreadsheet timesheet: re-enter current open projects as clients in Oto, then track hours there and invoice straight from the log.
- →From a separate receipt-tracking app: upload outstanding receipts as expenses so reimbursement history sits beside the invoice it belongs to.
- ↗To Bonsai: if you need multi-user support or deeper contract and project workflows, export your client list and documents and rebuild the pipeline there.
- ↗To FreshBooks: if you need stronger accounting and reporting, export invoice and expense data as PDFs and re-enter opening balances there.
- ↗To a dedicated accounting package: take your Oto invoice PDFs and expense records as the source documents for a bookkeeper to set up your ledgers.
