Why Small Businesses Should Bundle Invoices for Better Cash Flow
The $0.30 flat fee is killing your margins on small invoices. Bundling them into one is the easiest fix you'll ever make.
How the Flat Fee Scales (Stripe 2.9% + $0.30)
$25 invoice
1.2% of total
just the flat fee
$100 invoice
0.3% of total
just the flat fee
$1,000 invoice
0.03% of total
just the flat fee
The flat fee becomes negligible as invoice size grows — that's the argument for bundling.
If you're running a service business where clients pay for small deliverables throughout the month — hourly work, revision rounds, small add-ons — you may be unknowingly inflating your effective processing rate by sending too many small invoices.
The Math That Makes This Obvious
Imagine you invoice a client four times in a month for $150 each — one per project phase:
❌ Four Separate $150 Invoices
✅ One Bundled $600 Invoice
You saved $0.90 on one client this month. Multiply that by 20 clients and 12 months and it's $216/year saved just by changing when you send invoices — with zero other changes to your business.
How to Implement Monthly Bundling
Set a Billing Date
Pick the 1st or 15th of each month as your invoice day for recurring clients.
Track Work Weekly
Log deliverables in a simple spreadsheet or note — then roll them into one invoice.
Invoice Once, Get Paid Once
One invoice, one flat fee, one payment — and better cash flow for your client too.
