The verdict in three sentences
In B2B, bank transfers kill cash flow: manual bank-detail entry, forgotten payments, painful matching. Replacing bank details with a clickable Wave or Paystack payment link cuts payment delay by about 40 % and drops DSO from 45 to 18 days. The link adds a 1-2.9 % fee, largely offset by the cash freed and automated reconciliation.
Payment link vs classic transfer
The link turns a passive invoice into a one-click action. The difference shows mainly in delay and in the hidden cost of manual matching.
| Criterion | Transfer / bank details | Payment link |
|---|---|---|
| Average payment delay | 30-45 days | 12-18 days |
| Typical DSO | 45 days | 18 days |
| Open rate | — | ~65 % |
| Fees | ~0 % (but slow) | 1-2.9 % |
| Reconciliation | Manual | Auto by reference |
| Reminders | Manual | Automatic |
A DSO going from 45 to 18 days means 27 days of cash recovered on each invoice: on a tight order book, that is often the difference between paying suppliers on time or not.
Fees, limits and reconciliation
Fees and limits vary by provider and amount. Build them into your price or absorb them depending on your margin.
| Provider | Indicative fees | Limit per link (order of magnitude) | Reconciliation |
|---|---|---|---|
| Wave Business | 1-1.5 % | High, account-based | By invoice reference |
| Paystack | 1.5-2.9 % | KYC-based | Webhook + reference |
| Orange Money B2B | 1-2 % | Account-limit based | By reference |
| Bank transfer | ~0 % | Unlimited | Manual |
The operational key: encode the invoice reference in the link. The payment then reconciles itself in your software, no re-entry, and triggers archiving and automatic follow-up if unpaid.

Mini case study
Aminata runs an events agency in Dakar billing 30 B2B clients per month, average ticket 450,000 FCFA, i.e. 13,500,000 FCFA of monthly billing. With transfers, her DSO is 45 days: at any moment, 20,250,000 FCFA sit in receivables. Switching to Wave links (1.2 % fee), DSO drops to 18 days: outstanding falls to 8,100,000 FCFA. She frees 12,150,000 FCFA of cash, at a cost of 162,000 FCFA in monthly fees. Auto-reconciliation also saves her 2 days of admin work per month.
FAQ
How much does a link cut payment delay? About 40 % in B2B, moving DSO from 45 to 18 days. The client pays in one click from their phone instead of entering bank details at the bank.
What fees should I expect? Between 1 and 2.9 % by provider (Wave around 1-1.5 %, Paystack 1.5-2.9 %). Many B2B firms pass them on or absorb them given the cash gained.
How does reconciliation work? By encoding the invoice reference in the link: the payment matches automatically, no re-entry, and marks the invoice "paid" in your software.
Does the link fully replace transfers? For mid-range amounts, yes. For very large amounts exceeding mobile money limits, transfers remain an option, often alongside a tracking link.
Does Kolonell set this up? Yes: automatic Wave/Paystack link generation at invoice issue, encoded reference, automatic follow-up and a DSO dashboard.
