The verdict in three sentences
For a firm invoicing 300 business clients, the problem is not accepting a payment but shortening days sales outstanding and the time spent on reconciliation. The right setup combines a payment link on every invoice (ACH and card through a processor), wire transfer for large amounts and automatic reconciliation in the invoicing tool. Done well, it cuts average payment time by 15 to 25 days and frees a significant amount of working capital.
The B2B payment landscape in New York in 2026
In New York, many corporate clients still pay by check or by wire after several reminders, while accounts payable teams increasingly prefer ACH and virtual cards. Payment processors let you accept ACH and cards with a single integration, and AR automation platforms add reminders and a customer portal. For the vendor, the key is steering each invoice to the cheapest method the client will actually use.
| Payment method (2026 market estimate) | Vendor fees | Time to funds | Practical limit | Reconciliation |
|---|---|---|---|---|
| ACH via processor | 0.5 to 1%, often capped at USD 5 to 10 | 2 to 4 business days | high | automatic by invoice reference |
| Same-day ACH | USD 1 to 5 extra per payment | same day | per-payment limits apply | automatic |
| Credit or debit card | 2.9 to 3.5% | 2 days | card limits | automatic |
| Wire transfer | USD 15 to 35 incoming | same day | none | manual without structured reference |
| Paper check | USD 0 (plus lockbox fees if used) | 5 to 10 days after mailing | none | manual |
The practical rule in 2026: offer card payment for invoices under USD 2,000, push ACH as the default for everything else, and keep wire with a structured invoice reference for very large amounts, so you do not pay 3% on big tickets.
Implementation options
| Option | Setup cost | Recurring cost | Lead time | Main limit |
|---|---|---|---|---|
| Manual payment links from the processor dashboard | USD 0 | transaction fees | 1 week | no link to invoicing, manual reconciliation |
| Online invoicing or AR automation software | USD 0 to 2,000 | USD 50 to 500 per month | 2 to 4 weeks | rigid with complex invoices and custom workflows |
| Payment portal integrated with invoicing (custom) | 2,500,000-4,000,000 FCFA (Kolonell grid, EUR 3,810-6,100) | maintenance 35,000 to 120,000 FCFA per month | 6 to 10 weeks | upfront investment |
The custom portal, in Kolonell's simple application band (2,500,000-4,000,000 FCFA, i.e. EUR 3,810-6,100), includes: a unique link per invoice, a branded payment page, a choice of method (ACH, card, wire instructions), confirmation webhooks, automatic matching, email reminders at D-3, D+7 and D+15, and a receivables dashboard per client.
Why automatic reconciliation matters so much
Without a reliable reference, an accountant spends hours matching a transfer from 'ACME LLC' to one of its 12 open invoices. With one link per invoice, each payment arrives with the invoice ID: matching happens on its own and reminders stop automatically. That is also what makes reminders credible, because you no longer chase a client who has already paid.
Mini case study
Daniel, CFO of a 45-person IT services firm in New York, issues 3,600 invoices a year to 300 clients, averaging USD 4,000, i.e. USD 14.4 million invoiced. Average DSO is 55 days. With the portal and automated reminders, the target is 35 days: 20 days saved free about USD 790,000 of working capital. At an 8% credit line cost, that is USD 63,000 a year. If 30% of invoiced value goes through the link, mostly by ACH at an average effective 0.4%, fees are about USD 17,000, and automatic reconciliation saves around 34 accounting hours a month. Net gain of roughly USD 50,000 a year for an investment of 3,000,000 FCFA (about EUR 4,570) plus 75,000 FCFA of monthly maintenance: payback within a few months. Illustrative scenario to recalculate with your own figures.

FAQ
Can we pass card fees on to the client?
Surcharging is allowed in New York under strict disclosure rules, but in B2B it creates friction. Common 2026 practice is to absorb fees on small invoices and steer amounts over USD 2,000 to ACH.
Is ACH suitable for every client?
Yes for most US businesses: their AP teams already pay suppliers that way. Some large accounts insist on their own supplier portal, in which case you upload the invoice there and keep the link as a fallback.
How long to connect my invoicing software?
Allow 6 to 10 weeks for a full portal if your software exposes an API or an export. Without an API, a daily invoice import is enough and adds 1 to 2 weeks.
Are payments secure?
Processors handle card data under PCI DSS; your portal never stores a card number. Every confirmation goes through a signed webhook, verified before the invoice is marked paid.
What adoption rate can we expect?
2026 benchmark: 25 to 40% of invoices under USD 5,000 paid by link within the first 6 months, especially when the link appears on the PDF invoice, in the email and in the reminder.
