Invoice Simple does what its name says: fast, simple invoices and estimates for almost any kind of small business. Plenty of tradespeople start there.
ForgeBill is built around how a trade job actually runs, from quote to approval to the job itself to payment. If you have outgrown "make an invoice and email it," this comparison is for you.
Choose Invoice Simple if
- You only send a few invoices and never need a job record between quote and invoice.
- You are not in a trade and want a general-purpose invoice app.
- You want the lowest possible monthly cost for basic invoicing.
Choose ForgeBill if
- You want customers to approve quotes online and have a record of what they approved.
- You want job photos, notes, and sign-off attached to the work before you invoice it.
- You want unpaid invoices followed up automatically, without capped invoice counts.

Where Invoice Simple is stronger
It is quick to learn and works for any business type. If your work is one visit and one invoice, and you rarely need to show a customer what they approved, a simple invoice app may be all you need.
Where ForgeBill fits better
Trade jobs have a middle: the customer approves a price, you do the work, things change, and then you bill. ForgeBill keeps that middle on record. The approved quote becomes a work order with photos and sign-off, and the finished work becomes the invoice, so line items do not get retyped or forgotten.

What ForgeBill does
ForgeBill covers one job from first price to final payment: a quote with an online approval page, a work order with photos and customer sign-off, then an invoice with an optional Stripe payment link for card, Apple Pay, Google Pay, and supported bank payments. Automatic email reminders follow up on unpaid invoices, and reports show what is quoted, invoiced, collected, and outstanding.
It runs on iPhone, Android, and the web, and the mobile app keeps working offline for supported records. Pro is $19.99/month or $199.99/year, and you can start with the free plan: 3 sent invoices or quotes a month, no credit card.
Frequently asked questions
Is ForgeBill harder to use than Invoice Simple?
You can create a direct invoice in ForgeBill without starting from a quote or work order, so basic invoicing works the same way. The extra steps are there when you want them.
Can I keep my invoice numbering when I switch?
Check ForgeBill's invoice settings to continue from your last number, and keep your old app until open invoices are paid.
Do both apps take card payments?
Yes. ForgeBill uses Stripe for card, Apple Pay, Google Pay, and supported bank payments. Invoice Simple works with Stripe and PayPal, and those processors set the fees. Check both before deciding.
