Common savings range up to 0.50% of volume. At $50,000 a month in sales, that's up to $3,000 per year recovered. At $100,000 a month, the number becomes material. At $5,000,000, it's a new car. Most merchants never look.
How payment optimization works
Optimization starts with your processing statement. Most merchants receive a statement every month and never analyze it in detail. CambridgeCommerce does. We look at your effective rate, your pricing model, your interchange qualification rates, and the fees that appear in the fine print.
From there, we identify where you're paying more than you should, what structural changes would reduce your cost, and whether your current processor is the right long-term fit. This is not a sales exercise. If what you have is competitive, we tell you. If it isn't, we tell you what a better structure looks like and what it would take to get there.
Where merchants lose the most
- Flat-rate or tiered pricing that hides the actual interchange cost; often adding 0.30% to 0.60% above what interchange-plus would cost at the same volume
- Non-qualified downgrade surcharges triggered by card type or ansaction data that could be controlled with proper setup
- Missing Level 2 and Level 3 data on B2B card transactions; leaving interchange credits unclaimed on corporate and purchasing cards
- Gateway fees, monthly minimums, and batch fees that accumulate and are rarely reviewed against the market
- Processor markup above interchange that was negotiated years ago and never renegotiated as volume grew
- Surcharging programs implemented incorrectly; creating compliance exposure without delivering the intended cost offset
What we review and what we can change
Pricing model review
Flat-rate, tiered, and interchange-plus each work differently at different volumes. We identify which structure fits your transaction profile and what the actual cost difference is before recommending any change.
Interchange qualification
Transactions downgrade to higher interchange categories when required data fields are missing or authorization timing is off. We identify the specific downgrades in your statement and what's causing them.
Level 2 and Level 3 data
B2B merchants processing corporate, purchasing, or government cards can reduce interchange by 0.50% to 1.00% per qualifying transaction by passing enhanced transaction data. Most B2B merchants are not doing this.
Surcharging and cash discount
Properly implemented surcharging and cash discount programs can offset processing costs legally. Improperly implemented programs create card brand compliance violations. We review your program or help you build one correctly.
Statement audit
We review three months of statements to establish your effective rate, identify fee anomalies, and build a clear picture of what you're actually paying versus what you should be paying at your volume and transaction profile.
Rate negotiation
Processor markup above interchange is negotiable. Volume growth, low chargeback ratios, and long account tenure all create leverage. We handle the negotiation conversation on your behalf when the data supports it.
What "non-qualified" actually meaning: When a transaction downgrades to a non-qualified tier, it means your processor is charging you a surcharge on top of the base interchange rate. This often happens when rewards cards, corporate cards, or keyed transactions hit your account without the required data fields. The surcharge can range from 0.20% to 1.50% per transaction, applied silently, and it shows up on your statement in a category most merchants never look at.
