What's inside

Everything you need to bill, collect, and close the books.

Built around the day-to-day of field service work — not generic accounting software bolted onto invoicing.

Invoices that look the part

Clean, branded invoices that go out in under a minute. Line items, taxes, and terms — all auto-filled from past jobs.

Payments on autopilot

ACH, card, and Apple Pay built in. We chase late payers with polite reminders so you don't have to play collections.

Cash flow you can see

Know what's owed, what's overdue, and what's coming in this week. One dashboard, zero spreadsheets.

Clients, not contacts

Full history per client — every job, every invoice, every payment — without digging through email threads or file folders.

Tools to get you paid

Pay links, Quick Pay, and recurring subscriptions — however your customers want to pay, you're covered.

Books-ready exports

One-click exports to CSV or PDF. Clean, organized, and ready for your accountant the moment they ask.

By the numbers

The difference is measurable.

Operators moving from spreadsheets and Word docs to Invoice Fuel see it in their first month.

How it works

Three steps from job done to money in the bank.

01

Draft in seconds

Pick a client, add line items from your saved catalog, and taxes fill themselves in. Or duplicate last month's invoice with one click.

02

Send, then forget

Your client gets a clean email with a pay link. We track opens, reads, and follow up on overdue — automatically.

03

Cash hits your account

Payments land via ACH or card, synced to your books same day. You see what's paid and what's pending at a glance.

We categorize cards as Standard (typical bank-issued credit cards) and Premium (rewards or signature cards like Chase Sapphire or Amex Platinum).
Card payments settle in 2 business days (e.g., Monday transactions settle Wednesday). ACH standard funding settles in 4 business days; fast funding settles in 2 business days. Payout schedules are subject to change based on merchant underwriting, risk, and transaction limits.
Our ACH transactions have a maximum fee of $10.30 or $13.00 depending on your funding schedule. This means transactions over $1,000 will not incur a fee higher than that cap.
Surcharging allows you to add a fee (up to 3.00%) to credit card transactions to cover processing costs. It's only applicable to credit cards — not debit or ACH — and the maximum fee may change based on card network rules.
