Why billing is hard for consultantsMost invoicing tools weren’t built for how you work.
Paperwork that undercuts your rate
You charge premium fees, then send a proposal pieced together in a doc and an invoice that looks like everyone else’s. The mismatch undercuts the expertise you’re selling.
Retainers tracked by hand
Monthly advisory retainers should be the predictable part, but you’re recreating the same invoice every month and reconciling who paid in a spreadsheet.
Scope creep with no paper trail
An engagement expands over a few calls, but the agreement never changes. You either absorb the extra work or have an awkward conversation with a client you’re paid to advise.
How Tillage helps consultantsQuote, contract and get paid in one free tool.
Proposals worthy of your rate
Clean, line-itemed quotes with smart variables like
{clientName}, sent as a link your client approves online.app.tillage.ai
Contracts that tie scope to fee
Generate the contract from the approved quote, so the scope, price and terms you agreed are on paper and signed.

Retainers on autopilot
Set up a monthly retainer once. Tillage issues each invoice on schedule and tracks payment, and retainers roll into your MRR.

“I tried Bonsai for a few months and went back to Harvest. I needed written proposals and SOWs, and Harvest has never let me quote a range of time, hours or cost. Tillage is the first tool built around how I actually scope work.”
