For independent consultants and advisory firms

Invoicing software for consultants who bill scope, time and retainers

Invoice Crowd takes a consultant from a signed proposal to project time, expenses tagged to the client, retainers and the client invoice in one account.

  • Proposal approval and signature
  • Project and hourly billing
  • Retainers and expenses
Invoice Crowd Proposals screen for a consulting firm with diagnostic, market-entry and retainer proposals and their status, a signed engagement notification, unbilled project hours ready to invoice and a quarterly advisory recurring invoice schedule

The workflow

Make every consulting charge traceable to the engagement

Fixed diagnostics, hourly advisory work and monthly retainers are billed in different ways. Invoice Crowd keeps the scope, the hours, the costs and the invoices for an engagement in one place.

Agree the engagement

Scope and price before delivery starts

The Consulting Agreement proposal template in Invoice Crowd filled in for an operations diagnostic, with its phases and fees, and the engagement signed in the browser with the approval record

Put deliverables, fees and terms into a proposal

Create a proposal that explains the engagement, phases, price and terms, then let the client approve and sign it in the browser. When it is approved, convert the proposal into the first invoice.

  • Clear phases and commercial terms
  • Browser approval and signature
  • An approved proposal converts to an invoice
Build proposals

Support the variable fee

Project time stays attached to the work

Invoice Crowd timesheet for a consulting firm with advisory hours per project and task and their billing status, a running timer and the invoice preferences used to turn unbilled time into an invoice

Record time against the consulting project

Log time against the client's project and task, then bill the unbilled hours straight from that record. Clients can approve or question each week's hours in the customer portal before you invoice; they see hours, never rates. Each project's Profitability tab then sets the hours at your cost rate, and the expenses, against what you billed.

  • Time logged to a project and task
  • Weekly hours approved by the client
  • Profit and margin for each project

Separate fees from costs

Travel and research remain distinct records

Invoice Crowd expenses list for a consulting firm with travel, research, survey and workshop costs by category, and an expense tagged to a client and project with its receipt

Keep reimbursable expenses visible

Record travel, research and other business costs with the vendor, category, amount, tax and receipt. When your terms allow it, expenses tagged to a project can be re-billed on the next time invoice, with an optional markup.

  • Vendor and category detail
  • The receipt kept on the entry
  • Costs do not disappear into a fee total

Why it fits

Why consultants bill from here

Scope, hours, retainers and costs end up on the same invoice, so an engagement never has to be pieced together from four tools.

  • Hours, approvals and invoices in one record

    Time is logged, approved by the client and billed from the same project, so every hourly line has the entries behind it.

  • Retainers that count hours

    A retainer counts the hours you log against the monthly allowance, carries unused hours over or lets them expire, and bills extra hours on the next invoice. Paid plans.

  • Paid from the invoice

    Connect Stripe (including US bank payments), PayPal, GoCardless or ten others, and the client pays from the invoice.

  • Clients in other countries

    Invoice a client abroad in their currency while your reports total in yours, with the exchange rate stored on each invoice.

Also included

The rest of a consulting practice

These sit in the same account as your proposals, hours and invoices.

  • Client hour approvals

    Clients approve or question each week's billable hours on their project in the customer portal. They see hours, never rates.

  • Timesheet approvals

    Associates submit their week and you or a timesheet manager approve it, and a project can require approved time before it is billed. Paid plans.

  • Reminders and late fees

    Reminders go out before and after the due date. Set a flat or percentage late fee when you send the invoice, and it is added automatically if the invoice is still unpaid after the due date.

  • Retainers paid up front

    A retainer paid in advance is held as an advance with its own receipt, then applied to the invoices it covers.

  • Lock Transactions

    Lock a finished period so its numbers can't change once the books are closed. Only the owner can lock or unlock, and every change is logged. Paid plans.

  • AI Assistant

    Type “log 2h on the Northwind strategy review yesterday” and the assistant drafts the time entry for you to confirm. Paid plans, with AI credits.

  • Connect your other tools

    Send invoices, customers and expenses to your other tools through webhooks or Pabbly Connect.

  • TDS for clients in India

    Billing from India? When a client deducts TDS, record it with the payment and it is booked to TDS receivable.

  • Compare like with like

    When you compare tools, test each one on the same job: a fixed diagnostic, two hourly entries and a retainer.

Questions

Consultants invoicing, answered

Can consultants create and sign proposals in Invoice Crowd?

Yes. A proposal sets out scope, pricing and terms, and the client approves and signs it in the browser, by typing or drawing a signature.

Can I bill consulting work by the hour?

Yes. Log time to a project and task, then the invoice wizard bills the unbilled hours up to a date you pick, rounded to 6, 15 or 30 minutes if you want. Review the entries before you send the invoice.

Can I schedule a consulting retainer?

Yes. A recurring invoice handles a flat monthly fee. If the retainer covers a set number of hours, a retainer counts the time you log against that allowance, carries unused hours over or lets them expire, and bills extra hours on the next invoice without billing that time twice. Retainers need a paid plan.

How does Invoice Crowd fit with consulting CRM or resource planning?

Use Invoice Crowd for proposals, time, retainers, expenses, invoices, payments and the books, alongside the CRM or planning tool your firm already uses. There is no built-in CRM sync, but webhooks and Pabbly Connect can send invoices, customers and expenses across.

Can I record consulting travel and research costs?

Yes. Record each cost with its vendor, category, amount, tax and receipt. Tag it to the client's project and it can be re-billed on the next invoice, with a markup if your agreement allows.

Can consulting clients pay online?

Yes. Connect any of 15 gateways, such as Stripe (including US bank payments), PayPal or GoCardless, and the client pays from the invoice. The provider's own fees apply.
