The Thesis
The payment method a merchant offers is not neutral. It shapes who can buy, what they pay, how the merchant is perceived, and - critically - who owns the customer relationship after the transaction. Most comparisons focus narrowly on conversion rates or merchant fees. That framing misses the structural differences that determine long-term profitability.
But before we compare, a note on intellectual honesty that we think is worth stating upfront: no single payment model is universally superior. SNBL has real limitations - customers wait for the product, not everyone completes their plan, and the model requires education. Any comparison that tells you otherwise is selling you something. What follows is our honest attempt to map where each model works, where it breaks down, and what the data actually says.
The Four Models: An Honest Assessment
BNPL (Buy Now Pay Later)
BNPL providers - Klarna, Afterpay (Block), Zip, Scalapay - split purchases into short-term instalments (typically 3–4 payments over 6–8 weeks). The customer gets the product immediately; the provider assumes the credit risk.
The appeal is real: BNPL demonstrably increases checkout conversion for mid-ticket impulse purchases. Klarna's own data suggests conversion uplifts of 20–30% in certain categories. For fashion, electronics accessories, and beauty - products under €500 - BNPL works.
The problems emerge at scale and at high ticket values:
- Merchant fees of 5–8% are well-documented. Afterpay's investor disclosures show merchant fees averaging 5.5–6.5% of transaction value. For a €5,000 purchase, that is €275–€325 per sale.
- Transaction limits typically cap at €1,000–€1,500 for new users (based on published terms from Klarna, Afterpay, and Scalapay), making BNPL structurally unsuitable for high-ticket retail.
- The customer relationship transfers. Post-purchase, the customer interacts with the BNPL provider's app for payment reminders, not the merchant's.
- Regulatory pressure is mounting. The EU's revised Consumer Credit Directive (2023) brings BNPL under formal lending regulation.
EMI (Equated Monthly Instalments)
EMIs split purchases into fixed monthly payments through a bank or credit card provider. Interest is typically charged (though "0% EMI" promotions exist, subsidised by the merchant or issuing bank).
- Credit checks are mandatory, excluding customers with thin credit files or no credit history.
- The relationship sits with the bank. The instalment plan is between the customer and their financial institution.
- True cost is obscured. Even at "0% interest," someone pays - usually the merchant through subsidised rates or the customer through higher product pricing.
Traditional Credit / Loans
Store finance, personal loans, and revolving credit lines remain relevant for very large purchases (automotive, property), but for the €1,000–€20,000 range, the friction is disproportionate:
- Application processes deter customers. The FCA Financial Lives Survey (2020) found that a significant proportion of UK adults who could obtain credit chose not to apply because they found the process stressful or uncertain.
- Interest costs compound. Average personal loan rates in the EU range from 5–12% APR (ECB data).
- Once the loan is disbursed, the merchant is out of the picture.
SNBL (Save Now Buy Later)
SNBL enables customers to save toward a specific product over time. No lending, no credit, no debt. The trade-offs are real: the customer waits for the product, plan completion is not guaranteed, and customer education is required. But for merchants selling planned, aspirational purchases above €1,000, the structural advantages - full customer ownership, sub-1% fees, zero credit risk, and an extended engagement window - are significant.
The Comparison
The table below summarises the key differences. Where we cite specific numbers, sources are noted. Where data is based on typical market ranges, we say so.
| SNBL | BNPL | EMI | Credit / Loan | |
|---|---|---|---|---|
| Creates debt | No, it's saving | Yes | Yes | Yes |
| Interest charged | Never | Sometimes | Yes | Yes |
| Credit check | Never | Often | Yes | Yes |
| Merchant cost | ~1% | 5–8% ¹ | Varies | Varies |
| High-ticket suitable | Designed for it | Rarely | Limited | Limited |
| Customer ownership | Merchant | BNPL provider | Bank | Bank |
| Merchant control | Full | None | None | None |
| Engagement touchpoints | Throughout plan | Transaction only | Transaction only | Transaction only |
| Cross-sell opportunity | During plan | No | No | No |
| Requires regulation | No | Increasingly ² | Yes | Yes |
| Responsible spending | Built-in | Encourages debt | Debt-based | Debt-based |

What the Table Does Not Show
Comparison tables are useful, but they flatten nuance. Three things the table above cannot capture:
1. The Margin Impact Is Not Linear
The BNPL Fee at Scale
Sources: Afterpay investor reports, Klarna merchant disclosures
A 5–8% BNPL fee on a €50 purchase is €2.50–€4.00 - negligible. The same fee on a €5,000 purchase is €250–€400. At high ticket values, the merchant fee becomes a strategic cost, not a transaction cost.
2. Customer Ownership Compounds
When a BNPL provider owns the post-purchase relationship, the merchant loses more than data - they lose the ability to influence repeat behaviour. Over a customer's lifetime, this compounding loss of relationship is often more costly than the transaction fee itself.
3. Regulatory Risk Is Asymmetric
BNPL and EMI are lending products subject to consumer credit regulation, which is tightening across Europe. SNBL operates outside the consumer credit regulatory framework because it does not involve lending. As regulation increases compliance costs for lending-based models, this gap widens.
When Each Model Wins
No single payment model is optimal in all contexts:
Higher Urgency · Lower Ticket
BNPL
Fashion, beauty, accessories. Impulse-driven, checkout conversion matters most.
Higher Urgency · Higher Ticket
Credit / Loans
Automotive, property, major renovations. Large capital required immediately.
Lower Urgency · Lower Ticket
EMI
Electronics, appliances. Established customers, bank partnerships, moderate planning.
Lower Urgency · Higher Ticket
SNBL
Jewellery, furniture, travel, cosmetic procedures. Planned, aspirational purchases where the merchant values ownership and engagement.
This matrix is directional, not definitive. Overlap exists between categories, and individual merchant context matters more than any generic framework.
The Intellectual Honesty Test
SNBL has limitations: customers wait for the product, not everyone completes their plan, and the model requires customer education. These are real trade-offs, and merchants should evaluate them honestly against their specific business context.
But for merchants selling products above €1,000 - where margins matter, where the customer relationship matters, and where the purchase is planned rather than impulsive - the structural advantages of SNBL over lending-based alternatives are significant. The merchant pays less, retains more, and builds a relationship that extends beyond a single transaction.
The cost of a payment method is not just what you pay per transaction. It is what you give up - in margin, in data, in customer relationship, and in strategic flexibility.
