01 / Identify the problem first
What would this payment option improve?
A customer can use funds they already hold.
Bitcoin acceptance may serve customers who prefer to spend Bitcoin. That is a reason to investigate demand, not evidence that adding a logo will increase revenue. Ask customers whether they would actually use the option and for which purchases. Separate requests from completed sales when you assess the result.
A different route may suit a particular transaction.
Bitcoin can move across borders, and Lightning can support retail payments. Neither feature guarantees that a particular customer, wallet or merchant service is eligible. Check the countries, transaction limits, currencies and payment routes involved in your own sale.
The cost structure may differ.
Compare the complete cost of collecting usable proceeds. Include processing, conversion, network charges, withdrawals, equipment, staff time and bookkeeping. A headline processing rate does not capture the cost of handling a failed payment or a refund. Obtain the current provider quote and terms.
There is no automatic sales or margin gain. For a business whose customers never ask for crypto, the extra operational work may outweigh the benefit. For a business with repeated, specific requests, a limited pilot can provide better evidence than an industry adoption forecast.
