Free invoicing software built for agencies
Most invoicing tools were built for selling products, not billing client projects. Tillage runs your whole quote-to-cash workflow — AI quotes with profit protection, contracts, recurring invoices, and payments — free at $0/month, with platform fees you can pass to clients so you keep 100% of every invoice.
Why generic invoicing tools fail agencies
Agencies don't just send invoices. They scope projects, protect margins across a dozen clients, and bill on milestones and retainers. Off-the-shelf tools weren't built for that.
You undercharge and find out too late
You quote a redesign from memory, win it, and discover three weeks in that the scope grew but the price didn't. Generic invoicing tools show revenue, never margin — so you only learn a project lost money after it's delivered, when it's too late to fix.
Quotes, contracts, and invoices live in four tools
A proposal in one app, a contract in DocuSign, an invoice in a billing tool, and a spreadsheet tracking who paid. Every handoff means re-keying client details and line items, and every re-key is a chance to send the wrong number to the wrong client.
Payment fees quietly eat your margin
On a $12,000 project, a 3% card fee is $360 straight off your profit. Multiply that across every client every month and processing fees become one of your largest line items — yet most invoicing tools give you no way to pass them to the client.
How Tillage helps agencies
Everything from the first quote to the final payment in one workflow, priced to protect your margin.
AI quotes with profit built in
Describe the project in plain English and Tillage drafts a line-itemed quote with market-rate pricing, variance buffers, and a target profit margin already applied — so the number you send is a number you can actually deliver profitably.
See margin before you send
Every quote shows live profit and margin as you build it, and flags when a line item dips below your threshold. You catch the underpriced project on screen, not in the post-mortem.
Quote to contract to invoice, automatically
An accepted quote becomes a contract with eSignatures, and the signed contract seeds the invoice schedule — deposits, milestones, or recurring — with no re-keying. One source of truth from pitch to paid.
Keep 100% with fee pass-through
Accept cards and ACH through Stripe, and turn on fee pass-through so the client covers Stripe's processing fee and Tillage's 1% platform fee at checkout. You receive the full invoice amount.
Tillage vs. generic free invoicing tools
Free tools like Wave and Zoho Invoice are great at sending a basic invoice. Here's where an agency workflow needs more.
| Capability | Tillage | Generic free tools |
|---|---|---|
| Free plan ($0/month) | Yes | Yes |
| AI quoting with margin guardrails | Yes | No |
| Quote → contract → invoice flow | Yes, automated | No |
| Per-project profitability | Yes | No |
| Pass platform + processing fees to clients | Yes | Rarely |
| Full bookkeeping & tax filing | No — pairs with your accountant | Wave: yes |
Honest take: Where the incumbents win: if you need full double-entry bookkeeping, tax filing, or a decade-long brand track record, a dedicated accounting platform still beats us — Tillage owns the quote-to-cash workflow, not your general ledger. Many agencies run Tillage for client billing and keep an accountant for the books.
Built around agency reality
Tillage is shaped by how agencies actually bill — multi-client, milestone-based, margin-sensitive.
Multi-client by default
Client branding profiles, multiple contacts per client, and a billing dashboard that shows who owes what across every account at a glance.
Retainers that bill themselves
Set a monthly retainer once and Tillage generates and sends the recurring invoice on schedule, so predictable revenue stays predictable.
