Invoice Simple Alternative (2026–27): Free Unlimited Invoice & Receipt Maker vs $6.99–$19.99/Mo Plans

Short answer: Choosing an Invoice Simple alternative lets contractors, tradies, and self-employed freelancers send unlimited PDF invoices and estimates without hitting Invoice Simple’s 2-to-3 invoice trial wall or paying $6.99 to $19.99 every single month. By switching to Keel—a totally free invoice app ($0/month on iPhone, iPad, and iCloud Web Studio) that combines unlimited invoicing, job estimates, thermal receipt OCR, and statutory mileage logs—solo operators keep 100% of their margin.

Across DataForSEO backlink benchmarks (2,175 backlinks across 848 referring domains), Invoice Simple is one of the most widely cited mobile invoice apps on the web. Yet thousands of solo contractors, handymen, electricians, plumbers, and sole traders search for an invoice simple alternative every month after discovering two recurring bottlenecks: strict monthly document caps on starter tiers and repeated subscription price increases that turn a simple PDF generator into a $160 to $240+/year recurring bill.

Why do contractors and sole traders switch away from Invoice Simple?

1. The “3-Document Monthly Cap” Starter Plan Trap

A working plumber, HVAC technician, landscaper, or freelance consultant rarely sends only three bills in a 30-day cycle. Even a solo operator completing two small service calls a week issues 8 to 12 invoices and 10+ estimates every month. When an app’s entry-level plan caps you at a 3-document monthly limit, you are immediately forced onto the $13.99/month (10-document cap) or $19.99/month ($239.88/year) tier just to send PDF bills to your own customers.

2. Missing the Other Half of Job Profit: Receipts, Mileage & Tax Set-Asides

Sending an invoice is only Step 1 of running a profitable trade business. If you bill a client $2,400 for a deck repair or switchboard upgrade, your real taxable profit depends on:

• Job materials & supply house receipts: Home Depot, Lowe’s, Bunnings Trade, Mitre 10, PlaceMakers, or Screwfix dockets attached to that job;
• Work vehicle mileage: Driving to the quote, picking up supplies, and returning to the job site;
• Tax & GST/HST/VAT reserve: Knowing exactly how much belongs to the IRS, ATO, IRD, CRA, or HMRC before you spend the gross deposit.

Because Invoice Simple does not include a statutory mileage logbook or country-specific tax pack (Schedule C, Simpler BAS, IR3, T2125, SA103), contractors end up paying a second subscription for a mileage app and a third subscription for bookkeeping.

How does a 3-year cost comparison look across invoicing apps?

Pricing Tier / Scenario	Invoice Simple Plus ($13.99/mo)	Invoice Simple Premium ($19.99/mo)	Cloud Accounting + Mileage Stack (~$45/mo)	Keel On-Device Ledger ($0/mo Core)
1-Year Total Cost	$167.88	$239.88	$540.00	$0 / yr (optional one-time pack)
3-Year Total Cost	$503.64	$719.64	$1,620.00	$0 / yr (optional one-time pack)
What happens if you pause your subscription?	Cannot create new invoices or edit templates once trial/plan expires	Cannot create new invoices once plan expires	Read-only lockout or export deadline	Your data lives on your iPhone & iCloud forever — never locked behind a monthly bill

How do you migrate from Invoice Simple in 10 seconds without retyping your client list?

Contractors often delay switching away from a monthly subscription because they worry about losing their existing invoice numbering, logo layout, or repeat customer addresses. You can migrate in under a minute using two built-in pathways via the Switch & Import CSV/ZIP App Store Edition (?ppid=0dfe27bd-90b3-47f2-92df-72fbf06311a9):

1. Method A — Snap Any Existing Invoice PDF or Screenshot (On-Device OCR):
   • Open your most recent Invoice Simple PDF (or take a screenshot of an old invoice on your phone) and scan it in Keel.
   • On-device Apple Vision OCR automatically extracts your business name, tax ID (EIN, ABN, NZBN, GST/HST, UTR), next sequential invoice number, client details, and common line-item rates.
2. Method B — Import Your Client & Invoice CSV:
   • Export your invoice and client list as a CSV (or download our Blank CSV Template using the 🔗 Embed / CSV Template button in the workspace bar above) and import it directly into your local ledger.

What regional tax fields must your invoice generator support across US, AU, NZ, CA, and UK?

A generic invoice template often fails local tax audits if it omits statutory tax identifiers. Make sure every invoice you issue includes the mandatory fields for your jurisdiction:

• United States (IRS Schedule C & 1099-NEC): Business name, EIN or SSN (for W-9/1099-NEC reconciliation), itemised labor vs materials (crucial for state sales tax exemptions), and clear payment terms. See our what to include on an invoice guide.
• Australia (ATO GSTR 2013/1): The words “Tax Invoice” (if GST-registered), your 11-digit ABN, issue date, 10% GST amount (1/11th of GST-inclusive price), and buyer identity/ABN on invoices of A$1,000 or more incl. GST. See our Australian tax invoice template.
• New Zealand (IRD Taxable Supply Information): Your NZBN, GST number (if registered over NZ$60,000), 15% GST breakdown (3/23 of GST-inclusive total), and buyer details over NZ$200 incl. GST. See our NZ invoice template.
• Canada (CRA GST/HST & Revenu Québec QST): Your 9-digit Business Number (BN) + RT0001, exact provincial tax rate (5% GST, 13% ON HST, 14% NS HST, 15% Atlantic HST, or 5% GST + 9.975% QST in Québec). See our Canadian invoice template.
• United Kingdom (HMRC VAT & CIS): Sequential invoice number, 20% VAT or CIS Domestic Reverse Charge notice, and separate CIS labour (20% deduction) vs materials (0% deduction) lines. See our UK sole trader invoice requirements.

Is there a free version of Invoice Simple, or is there a totally free invoice app?

No — Invoice Simple does not offer a permanent free version. It only provides a brief free trial capped at 2 to 3 lifetime invoices, after which it requires a paid subscription (~$6.99/month for up to 3 invoices/month, $13.99/month for up to 10 invoices/month, or $19.99/month for unlimited invoices).

If you are looking for a totally free invoice app with zero monthly invoice cap, Keel (Keel: Invoice Generator) lets you create and send unlimited daily estimates, contractor work orders, and PDF invoices for $0/month on iPhone, iPad, and the iCloud Web Workspace—plus on-device receipt scanning and a tax mileage logbook with no bank connection required.

Frequently asked questions

Is there a free version of Invoice Simple, and what is the best totally free invoice app?

Invoice Simple does not have a permanent free plan; its free trial stops after your first 2 to 3 invoices and then charges $6.99 to $19.99/month. Keel (Keel: Invoice Generator) is the best totally free invoice app ($0/month) because you can generate unlimited PDF invoices, estimates, work orders, receipt scans, and mileage logs on iPhone, iPad, and the iCloud Web Workspace without a 3-invoice paywall or bank link.

Why did Invoice Simple start charging a monthly fee after my first few invoices?

Invoice Simple operates on a freemium trial model that allows new users to test the interface on a small number of documents (typically 2 to 3 invoices) before requiring a monthly or annual subscription tiered by how many documents you send each month ($6.99/mo for a 3-document monthly cap, $13.99/mo for a 10-document cap, or $19.99/mo for unlimited).

Can I bring my existing invoice numbers and clients over from Invoice Simple?

Yes. You do not need to start back at Invoice #001. You can set your starting invoice number to match your next sequential number (for example, INV-1048), import your customer and invoice history via CSV, or photograph a single past PDF invoice so on-device OCR populates your business header and line items automatically.

Does an offline-first invoice app work on job sites with no cell reception?

Yes. Unlike cloud-only web wrappers that fail to load templates or customer lists when you are in a basement mechanical room or a rural job site, an on-device iOS ledger stores your clients, price book, estimates, and invoices locally on your iPhone and syncs privately through your own Apple iCloud when you return to coverage.

Can I track my receipts and work mileage in the same app as my invoices?

Yes. Instead of paying $19.99/month for an invoice app plus another $15–$25/month for a receipt scanner and mileage tracker, Keel links your job estimate, final invoice, photographed supply house receipts, and statutory business mileage trips under the same client and job record.
