Invoicing software for consultants and advisory work
Consulting is sold on trust and billed on value — your paperwork should reflect that. Tillage gives consultants polished proposals, retainer and milestone invoicing, and integrated payments in one free workflow, with margin protection so your rate reflects the value you deliver.
The consultant's billing problem
You sell expertise, but you still have to package it, contract it, and collect on it — usually across disconnected tools that make a premium service feel clumsy.
Proposals that don't match your fees
You charge premium rates, then send a proposal cobbled together in a doc and an invoice from a basic tool that looks like everyone else's. The mismatch undercuts the very expertise you're asking the client to pay a premium for.
Retainers tracked by hand
Monthly advisory retainers should be the easy, predictable part — but you're manually recreating the same invoice every month, remembering due dates, and reconciling who's paid in a spreadsheet that's always slightly out of date.
Value pricing with no margin visibility
You price on outcomes, not hours, which is right — but without a clear view of your cost to deliver, you can't tell whether a fixed-fee engagement is actually profitable until the engagement is over and the hours are spent.
Scope creep with no paper trail
An advisory engagement quietly expands over a few calls, but the agreement never changes. Without a contract that ties scope to fee — and a record of what was agreed — you either absorb the extra work or have an awkward conversation that strains the relationship you're paid to protect.
How Tillage helps consultants
Package, contract, and bill advisory work in a way that matches the quality of your advice.
Proposals worthy of your rate
Generate clean, professional, line-itemed proposals in minutes, with smart variables that personalize each one to the client — so the paperwork signals the same quality as the work.
Retainers on autopilot
Set up a monthly advisory retainer once and Tillage generates and sends the recurring invoice on schedule, then tracks payment automatically — no manual rebuilding, no missed months.
Protect the margin on fixed fees
Enter your cost to deliver and Tillage shows the margin on every fixed-fee engagement, flagging the ones priced too thin before you commit to them.
Get paid in full, faster
Collect by card or ACH through Stripe, pass the processing and platform fees to the client, and let automatic reminders handle the awkward follow-ups.
Tillage vs. generic invoicing tools
Basic tools can send an invoice. Advisory work needs proposals, retainers, and margin visibility too.
| Capability | Tillage | Generic invoicing tools |
|---|---|---|
| Free plan ($0/month) | Yes | Yes |
| Professional proposals | Yes | Basic |

Honest take: Where the incumbents win: full bookkeeping, tax filing, and long brand track records. Tillage runs the client-facing side — proposals, retainers, invoicing, payments — and leaves the general ledger to your accountant.
Fits how advisors actually work
Built around engagements and retainers, not product catalogs.
Engagements, not SKUs
Package advisory work as proposals and statements of work with clear scope, so the fee is anchored to outcomes and the agreement is on record.
Predictable revenue
Recurring retainers bill and reconcile themselves each month, smoothing the feast-or-famine cycle that comes with project-only work.
