Setup Best Practices
Before You Start:
- • Gather business documentation
- • Set up business banking account
- • Determine your transaction volume
- • Plan integration with existing systems

- • Test with small transactions first
- • Configure fraud protection settings

Cost Optimization Strategies
Negotiate Volume Discounts
If processing over $10,000/month, contact providers directly for custom rates. Even 0.1% savings equals $120/year on $10k monthly volume.
Encourage Lower-Cost Payment Methods
ACH transfers cost 0.8% vs 2.9% for cards. Offer small discounts for ACH payments to improve your margins on larger transactions.
Monitor and Analyze Transaction Data
Track fees monthly and identify patterns. High international transaction volumes might justify switching to a provider with better international rates.
Frequently Asked Questions
What's the best payment processor for small businesses?
It depends on your business type and volume. Square is excellent for in-person retail, Stripe for online businesses with developer resources, and PayPal for quick setup and buyer trust. Consider your monthly volume, transaction types, and technical requirements.
How much should I expect to pay in processing fees?
Most processors charge 2.6-2.9% + $0.30 per transaction for credit cards. Debit cards are typically cheaper at 1.5-2.5%. High-volume businesses can often negotiate better rates, especially for transactions over $1,000.
Do I need a separate merchant account?
Payment aggregators like Stripe, Square, and PayPal don't require separate merchant accounts - they're included. Traditional processors may require dedicated merchant accounts, which offer more control but involve longer setup times.
How do international payments affect processing costs?
International transactions typically cost 1-2% more than domestic ones. Currency conversion adds another 1-4%. If you serve international customers regularly, choose a processor with competitive international rates like Stripe or PayPal.
