Deposits and progress billing
Roofers take deposits for materials and bill progress payments. Written contracts and invoices that reference them protect against disputes.
Storm season
After a storm, volume can jump overnight. Providers watch for spikes, so agree a higher limit in advance and explain your seasonality.
Insurance-funded jobs
Homeowners paying with insurance proceeds often pay by cheque or ACH; offering ACH avoids card fees on the largest payments.
Pricing
On large tickets the percentage dominates. Interchange-plus and ACH options matter more than fixed fees.
