Step-by-Step Switching Process

1 Review Your Current Contract

Before starting, understand your current situation:

✓ Things to Check:
⚠️ Warning: Some providers have auto-renewal clauses that can lock you in for another 12-36 months if you don't give notice in time. Check your contract NOW.
2 Research & Get Quotes

Gather 3-5 quotes from different providers:

✓ Information to Provide:
💡 Pro Tip: Use a comparison service like MerchantSwitch to get multiple quotes quickly. This saves time and ensures you're getting competitive rates.
3 Choose Your New Provider

Make your decision based on:

Factor What to Look For
Total Cost Not just transaction rate - include all monthly fees
Contract Terms Prefer rolling monthly or max 12 months
Settlement Speed 1-2 days is standard; same-day costs extra
Support UK-based, 24/7 availability for issues
Equipment Modern terminals with contactless & mobile wallet support
4 Submit Application
✓ Documents You'll Need:

Timeline: Application takes 15-30 minutes. Approval typically takes 2-5 business days.

5 Underwriting & Approval

The new provider will review your application and may:

Timeline: 3-7 business days for most businesses. High-risk industries may take longer.

💡 Tip: Respond quickly to any requests for information. Delays in providing documents are the #1 reason switching takes longer than expected.
6 Equipment Delivery & Setup

Once approved, your new terminals will be delivered:

✓ What You'll Receive:

Timeline: 2-3 business days for delivery after approval.

Installation Options:

7 Training Your Staff

Ensure your team knows how to:

✓ Essential Training Items:

Timeline: 30-60 minutes for basic training. Schedule before your go-live date.

💡 Tip: Record a quick video of the training session for future staff reference. Most providers also offer online training videos.
8 Testing Phase (Critical!)

This is the most important step to avoid downtime:

✓ Testing Checklist:

Timeline: Allow 2-3 days for thorough testing, including settlement verification.

⚠️ Critical: Never go live without testing first. A 30-minute testing session can prevent hours of downtime and lost sales.
9 Parallel Running (Optional but Recommended)

For 3-7 days, run both old and new systems simultaneously:

Benefits: Zero risk of downtime. If anything goes wrong with the new provider, you can immediately fall back to the old system.

💡 Best Practice: For busy businesses (restaurants, retail stores), start parallel running on a quiet day (Monday/Tuesday) rather than Friday/Saturday.
10 Go Live!

When you're confident everything works:

✓ First Day Checklist:
11 Cancel Old Provider

Important timing: Only cancel your old provider AFTER successfully processing with the new provider for at least 3-5 days.

Frequently Asked Questions

Q: How long does switching take?

A: Typically 2-4 weeks from application to go-live. Can be faster (1 week) for simple setups or longer (4-6 weeks) for complex integrations.

Q: Will I have downtime?

A: No, if you follow the parallel running approach. You'll have both systems available during the transition.

Q: What if my old contract isn't up yet?

A: Check your early termination fees. Sometimes the savings from switching still make it worthwhile. Calculate: (Monthly savings × Months remaining) vs Early termination fee.

Q: Can I keep my merchant ID?

A: Sometimes yes, sometimes no. Ask your new provider. Keeping it maintains transaction history but isn't always possible.

Q: What happens to pending settlements?

A: The old provider will still settle any transactions processed on their system, even after you switch. This can take 3-7 days.

Q: Do I need to tell customers?

A: No. The switching process is invisible to customers - they just tap/insert their card as normal.
